[Summary of Invention]
[Technical Problem]
[0005]
In recent years, various liquid ejecting apparatuses have been
used, and also a liquid ejecting apparatus with long lifespan,
and which is based on the premise of being used while exchanging
an ejecting unit has been used. However, in such a liquid
ejecting apparatus, when an ejecting unit, a driving substrate,
and a control substrate which controls driving of the entire
liquid ejecting apparatus are accommodated in one
accommodating body, workability deteriorates when exchanging
the ejecting unit, since the driving substrate or the control
substrate becomes a nuisance. Meanwhile, even when a
configuration in which the ejecting unit, and the driving
2
substrate or the control substrate are accommodated in a
separate accommodating unit is adopted, workability when
exchanging the ejecting unit also deteriorates depending on the
configuration.
[0006]
Therefore, an object of the invention is to improve workability
when exchanging an ejecting unit.
[Solution to Problem]
[0007]
A liquid ejecting apparatus according to a first aspect of the
invention for solving the above described problem is a liquid
ejecting apparatus which ejects liquid onto a medium, the
apparatus including a carriage which includes a control
substrate which configures at least a part of a control unit
which controls driving of the entire liquid ejecting apparatus,
a plurality of ejecting units which eject the liquid, a
plurality of driving substrates which are connected to the
control substrate, connected to the plurality of ejecting units
in one-to-one correspondence, and drives the ejecting unit, an
ejecting unit-driving substrate accommodating unit which
accommodates the ejecting unit and the driving substrate, and
a control substrate accommodating unit which accommodates the
control substrate, in which the plurality of driving substrates
are connected to the control substrate.
[0008]
According to the aspect, the carriage which includes the
ejecting unit-driving substrate accommodating unit which
accommodates the ejecting unit and the driving substrate, and
a control substrate accommodating unit which accommodates the
control substrate, and in which the plurality of driving
substrates are connected to the control substrate is
provided. For this reason, when exchanging the ejecting unit,
for example, it is possible to exchange the ejecting unit by
collectively detaching the control substrate from the
plurality of driving substrates, and individually detaching a
driving substrate corresponding to an ejecting unit which will
3
be exchanged, from the ejecting unit, after making
room. Accordingly, it is possible to improve workability when
exchanging the ejecting unit.
[0009]
In the liquid ejecting apparatus according to a second aspect
of the invention, in the first aspect, the control substrate
may be collectively connected to all of the driving substrates.
[0010]
According to the aspect, the control substrate is collectively
connected to all of the driving substrates. For this reason,
it is possible to effectively improve workability,
particularly, when exchanging the ejecting unit.
[0011]
In the liquid ejecting apparatus according to a third aspect
of the invention, in the first aspect, the plurality of ejecting
units may be able to eject the liquid of a different type in
each group, and the control substrate may be collectively
connected to the driving substrate, in each group.
[0012J
According to the aspect, the plurality of ejecting units are
able to eject liquid of different types in each group, and the
control substrate is collectively connected to the driving
substrate in each group. In the configuration in which liquid
of different types can be ejected in each group, since the
ejecting unit is exchanged in each group, in general, it is
possible to improve workability when exchanging the ejecting
unit, in the configuration in which liquid of different types
can be ejected in each group. In addition, since it is possible
to reduce the number of times of disconnecting the control
substrate from the driving substrate (without detaching
driving substrate in group which is not exchanged from control
substrate), it is possible to suppress a damage of a connecting
unit which is caused when disconnecting the control substrate
from the driving substrate.
[0013]
4
In the liquid ejecting apparatus according to a fourth aspect
of the invention, in any one of the first to third aspects, the
ejecting unit-driving substrate accommodating unit and the
control substrate accommodating unit may be connected by a
connector terminal.
[0014]
According to the aspect, the ejecting unit-driving substrate
accommodating unit and the control substrate accommodating
unit are connected by the connector terminal. For this reason,
it is possible to improve workability when connecting and
disconnecting the ejecting unit-driving substrate
accommodating unit and the control substrate accommodating
unit.

[Description of Embodiments]
[0016]
Hereinafter, a recording apparatus according to an embodiment
of the invention, as a liquid ejecting apparatus, will be
described with reference to accompanying drawings.
[First Embodiment] (Figs. 1 to 9)
[0017]
First, an outline of a recording apparatus 1 according to a
first embodiment of the invention will be described.
[0018]
Fig. 1 is a schematic perspective view of the recording
apparatus 1 in the embodiment. Fig. 2 is a schematic plan view
which illustrates the recording apparatus 1 according to the
embodiment. Fig. 3 is a schematic front view of the recording
apparatus 1 according to the embodiment. Fig. 4 is a schematic
side view of the recording apparatus 1 according to the
embodiment. In addition, Fig. 5 is a schematic rear view of
the recording apparatus 1 according to the embodiment. In
addition, Figs. 1 to 5 illustrate a state in which a part of
constituent members is detached from the recording apparatus
1 of the embodiment, and for example, a state in which a
sub-carriage 5 (refer to Fig. 6) is detached from the carriage
6.
[0019]
The recording apparatus 1 according to the embodiment is
provided with a transport mechanism 3 which transports a medium
for recording in a transport direction A using an adhesive belt
2 (endless belt) which supports the medium for recording
(medium) on a supporting face to which an adhesive is
7
attached. In addition, a feeding unit (not illustrated) in
which a roll-shaped medium for recording can be set, and it is
possible to send out the medium for recording to the transport
mechanism 3 is provided. In addition, a recording mechanism
4 which performs recording by causing a carriage 6 including
a recording head 7 as the ejecting unit to perform reciprocating
scanning in a reciprocating direction B which intersects the
transport direction A of the medium for recording is provide
in a transport region of the medium for recording using the
transport mechanism 3. A winding mechanism (not illustrated)
which can wind up the medium for recording, on which recording
is performed in the recording mechanism 4, is further provided.
[0020]
The transport mechanism 3 in the embodiment is provided with
the adhesive belt 2 which transports the medium for recording
sent out from the feeding unit, by mounting thereof, a driving
roller 8 which moves the adhesive belt 2, and a driven roller
9. The medium for recording is mounted on a support face of
the adhesive belt 2 by being attached thereto.
[0021]
However, the endless belt as the transport belt is not limited
to the adhesive belt. For example, an electrostatic
attraction-type endless belt may be used.
[0022]
In addition, the recording apparatus 1 according to the
embodiment is provided with the transport mechanism 3 with such
a configuration; however, it is not limited to the transport
mechanism with such a configuration, and it may be a
configuration in which the medium for recording is transported
by being supported by a mobile support tray, or the like, a
configuration in which the medium for recording is transported
using a pair of rollers, or the like. In addition, the
recording apparatus may be a so-called flat bed-type recording
apparatus in which recording is performed by fixing the medium
for recording to the support unit, and moving the recording head
7 with respect to the fixed medium for recording.
8
[0023]
The recording mechanism 4 includes a carriage motor 30 (refer
to Fig. 9) which causes the carriage 6 provided with the
recording head 7 which can eject ink (liquid) to reciprocate
in the reciprocating direction B.
[0024]
The recording apparatus 1 according to the embodiment performs
recording by causing the carriage 6 including the recording
head 7 to perform reciprocating scanning, when performing
recording; however, the transport mechanism 3 stops
transporting of the medium for recording in the middle of
recording scanning (in the middle of moving of carriage 6) In
other words, reciprocating scanning of the carriage 6, and
transporting of the medium for recording are alternately
performed, when performing recording. That is, when
performing recording, the transport mechanism 3 is
intermittently transported (intermittent moving of adhesive
belt 2) corresponding to reciprocating scanning of the carriage
6.
[0025]
The recording apparatus 1 according to the embodiment includes
the recording head 7 which performs recording while
reciprocating; however, the recording apparatus may be a
recording apparatus which includes a so-called line head in
which a plurality of nozzles which eject ink are provided in
an intersecting direction which intersects the transport
direction A.
[0026]
Here, the "line head'' is a recording head in which a region of
nozzles which are formed in the intersecting direction which
intersects the transport direction A of the medium for
recording is provided so as to cover the entire intersecting
direction of the medium for recording, and which is used in a
recording apparatus which form an image by relatively moving
a recording head or a medium for recording. In addition, a
region of the nozzles in the intersecting direction of the line
9
head may not cover the entire intersecting direction of all of
mediums for recording to which the recording apparatus
corresponds.
[0027]
In addition, the ''carriage" in the invention means a carriage
which includes an ejecting unit, and is used by having a
configuration in which a medium and an ejecting unit can be
relatively moved. For this reason, the line head (or
accommodating unit which accommodates line head) is also
included in the carriage in the invention.
[0028]
A rail lOa which extends in the reciprocating direction B is
formed in a pipe lla which configures a skeleton portion of the
recording apparatus 1 of the embodiment, and a rail lOb which
extends in the reciprocating direction B is formed in a pipe
llb which configures the skeleton portion of the recording
apparatus 1 of the embodiment. In addition, a movement in the
reciprocating direction B of the carriage 6 in the embodiment
is guided by the rail lOa and rail lOb, when a bearing (not
illustrated) is received in the rail lOa and rail lOb.
[0029]
An air blowing unit 12 which extends in the reciprocating
direction B, and sends air in a direction opposite to the
transport direction A from a plurality of blasting ports (not
illustrated) is further provided at a position in the lower part
of the pipe llb. In addition, a mist collecting unit 13 which
extends in the reciprocating direction B, and can collect mist
of ink ejected from the recording head 7 is provided in the lower
part of the pipe lla. A collecting port 16 which extends in
the reciprocating direction B is provided in the lower part of
the pipe lla, in the mist collecting unit 13.
[0030]
In addition, as illustrated in Fig. 3, a plurality of (three)
air blowing fans 14 which generate a blasting force using the
air blowing unit 12 are provided on the downstream side in the
transport direction A of the recording apparatus 1 of the
10
embodiment. Due to the blasting force which is generated by
the air blowing fan 14, the air blowing unit 12 can send air
toward the collecting port 16 from the outside (position on
downstream side in transport direction A) of the collecting
unit 13. In addition, as illustrated in Fig. 5, a plurality
of (three) suctioning fans 15 as a suctioning unit which
generate an air current from the collecting port 16 toward the
inside of the collecting unit 13, and from the inside of the
collecting unit 13 toward the outside of the recording
apparatus 1 are provided on the upstream side in the transport
direction A of the recording apparatus 1 in the embodiment.
[0031]
Subsequently, the carriage 6, and a sub-carriage 5 mounted on
the carriage 6 which are main portions of the recording
apparatus 1 of the embodiment will be described.
[0032]
Here, Fig. 6 is a schematic front view of the carriage 6. Fig.
7 is a front perspective view which schematically illustrates
the sub-carriage 5. In addition, Fig. 8 is a side perspective
view which schematically illustrates the sub-carriage 5.
[0033]
As illustrated in Fig. 6, the carriage 6 in the embodiment is
configured so that it is possible to perform reciprocating
scanning in the reciprocating direction B by mounting the
plurality of sub-carriages 5.
[0034]
As illustrated in Figs. 7 and 8, the sub-carriage 5 includes
a control substrate accommodating unit 19 which accommodates
a control substrate 41 configuring a part of a control unit 23
(refer to Fig. 9) which controls driving of the entire recording
apparatus 1, and an ejecting unit-driving substrate
accommodating unit 20 which accommodates the recording head 7,
and a driving substrate 40 which drives the recording head
7. In addition, the control substrate accommodating unit 19
and the ejecting unit-driving substrate accommodating unit 2 0
are connected using a connecting portion 38 (connector
11
terminal) on the control substrate accommodating unit 19 side,
and a connecting portion 39 (connector terminal) on the
ejecting unit-driving substrate accommodating unit 20
side. In addition, the driving substrate 40 and the recording
head 7 are connected through a load absorbing unit 42.
[0035]
As illustrated in Figs. 7 and 8, a fixing portion 21 which fixes
the driving substrate 40 which is connected to the carriage 6
is provided above the driving substrate 40 in the ejecting
unit-driving substrate accommodating unit 20 between the
control substrate accommodating unit 19 and the ejecting
unit-driving substrate accommodating unit 20. In other words,
the fixing portion 21 which fixes a position of the driving
substrate 40 with respect to the recording head 7 is provided
on the upper side (side opposite to recording head 7) of the
driving substrate 40, in the carriage 6 (sub-carriage 5).
[0036]
In addition, as illustrated in Figs. 7 and 8, the driving
substrate 40 according to the embodiment is provided along a
direction of the recording head 7 (direction which goes along
vertically upper direction C) with respect to the driving
substrate 40. In other words, the driving substrate 40
according to the embodiment is disposed so as not to face the
recording head 7. For this reason, it is possible to
efficiently prevent heat generated by the driving substrate 40
from being transmitted to the recording head 7.
[0037]
Subsequently, an electrical configuration in the recording
apparatus 1 in the embodiment will be described.
[0038]
Fig. 9 is a block diagram of the recording apparatus 1 according
to the embodiment.
[0039]
A CPU 24 which controls the entire recording apparatus 1 is
provided in the control unit 23 which controls driving of the
entire recording apparatus 1 in the embodiment. The CPU 24 is
12
connected to a ROM 26 which stores various control programs
which are executed by the CPU 24, and a RAM 27 which can
temporarily store data through the system bus 25.
[0040]
In addition, the CPU 24 is connected a head driving unit 28 for
driving the recording head 7 through a system bus 25.
[0041]
In addition, the CPU 24 is connected to a motor driving unit
29 which drives a carriage motor 30, a transport motor 31, a
feeding motor 32, a winding motor 33, an air blowing fan motor
17, and a suctioning fan motor 18 through the system bus 25.
[0042]
The carriage motor 30 is a motor for moving the carriage 6
including the recording head 7. In addition, the transport
motor 31 is a motor for driving the driving roller 8. In
addition, the feeding motor 32 is a driving motor of the feeding
unit which sends out a medium for recording which is set in the
feeding unit (not illustrated) to the transport mechanism
3. The winding motor 33 is a driving motor for driving a winding
mechanism (not illustrated) in order to wind a medium for
recording on which recording is performed. The air blowing fan
motor 17 is a motor for driving the air blowing fan 14. In
addition, the suctioning fan motor 18 is a motor for driving
the suctioning fan 15.
[0043]
In addition, the CPU 24 is connected to an input-output unit
34 through the system bus 25, and the input-output unit 34 is
connected to a PC 35 for performing transceiving of data such
as recording data, and signals.
[0044]
As described above, the recording apparatus 1 in the embodiment
is a recording apparatus which ejects ink onto a medium for
recording, and is provided with the carriage 6 including the
control substrate 41 which configures at least a part of the
control unit 23 which controls driving of the entire recording
apparatus 1, the recording head 7 which ejects ink, and the
13
driving substrate 40 which is connected to the control
substrate 41 and the recording head 7, and drives the recording
head 7.
[0045]
In addition, the carriage 6 is provided with the fixing portion
21 which fixes a position of the driving substrate 40 with
respect to a position of the recording head 7. For this reason,
a movement of the driving substrate 40 in a direction of
approaching, and a direction of separating from the recording
head 7, that is, pressing or pulling of the recording head 7
with respect to the driving substrate 40 is suppressed, and a
load which is applied to the recording head 7 from the driving
substrate 40 side is suppressed.
[0046]
In addition, as described above, the carriage 6 is provided with
the load absorbing unit 42 which absorbs a physical load with
respect to the recording head 7 from the driving substrate
40. For this reason, even when the driving substrate 40 moves
in the direction of approaching, and the direction of
separating from the recording head 7, a pushing force and a
pulling force of the driving substrate 40 with respect to the
recording head 7 is reduced, and a load which is applied to the
recording head 7 from the driving substrate 40 side is
suppressed.
[0047]
As described above, the carriage 6 in the embodiment is provided
with the ejecting unit-driving substrate accommodating unit 20
which accommodates the recording head 7 and the driving
substrate 40, and the control substrate accommodating unit 19
which accommodates the control substrate 41. For this reason,
in the recording apparatus 1 according to the embodiment, it
is possible to express that an application of a load to the
recording head 7 from the driving substrate 40 side is
suppressed, in the carriage 6 which is provided with the
ejecting unit-driving substrate accommodating unit 2 0 and the
control substrate accommodating unit 19.
14
[0048]
As illustrated in Figs. 7 and 8, the fixing portion 21 in the
embodiment fixes the position of the driving substrate 40 with
respect to the position of the recording head 7 from above. In
this manner, the recording apparatus 1 in the embodiment can
effectively suppress falling (position shift) of the
vertically long accommodating unit (ejecting unit-driving
substrate accommodating unit 20) which accommodates the
driving substrate 40, particularly, by being fixed from above
(vertically upward direction C) using the fixing portion 21.
[0049]
In addition, the fixing portion 21 in the embodiment fixes the
position of the driving substrate 40 with respect to the
position of the recording head 7 in the vertically upward
direction C; however, it may be a configuration of fixing the
position from the upper side, and a direction slightly shifted
from the vertically upward direction, not in the vertically
upward direction C in a strict sense.
[0050]
As illustrated in Figs. 7 and 8, the recording apparatus 1 in
the embodiment is provided with the plurality of recording
heads 7, and the plurality of driving substrates 40 which are
connected to the control substrate 41, and to the plurality of
recording heads 7 in one-to-one correspondence, in the carriage
6. In addition, the plurality of driving substrates 40 are
connected to the control substrate 41. With such a
configuration, when exchanging the recording head 7, the
recording apparatus 1 according to the embodiment can
collectively detach the control substrate 41 from the plurality
of driving substrates 40 (that is, detaching control substrate
accommodating unit 19 from ejecting unit-driving substrate
accommodating unit 20), detach a driving substrate 40
corresponding to a recording head 7 to be exchanged from the
recording head 7 individually, after making a space, and switch
the recording head 7. Accordingly, it is possible to improve
workability when exchanging the recording head 7.
15
[0051]
More specifically, the carriage 6 according to the embodiment
is divided into a group in each one or a plurality of
sub-carriages 5 which correspond to ink of different types. In
addition, one control substrate 41 is collectively connected
to the plurality of driving substrates 40 in each sub-carriage
5 (refer to Figs. 6 to 8).
[0052]
In other words, the plurality of recording heads 7 are
configured so as to eject ink of a different type in each group,
and the control substrate 41 is collectively connected to the
driving substrate 40 in each group. In the configuration in
which ink of a different type can be ejected, in general, since
the recording head 7 is exchanged in each group, workability
when exchanging the recording head 7 is improved. In addition,
since it is a configuration in which it is possible to reduce
the number of times of releasing a connection between the
control substrate 41 and the driving substrate 40
(configuration in which it is not necessary to also detach
driving substrate 40 in group which is not exchanged with
respect to control substrate 41), it is possible to suppress
a damage of the connecting portions 38 and 39 which is
associated with releasing of the connection between the control
substrate 41 and the driving substrate 40.
[0053]
Meanwhile, the control substrate 41 may be collectively
connected to all of the driving substrates 4 0. The reason for
this is that it is possible to effectively improve workability
when exchanging the recording head 7, particularly, when
exchanging a lot of recording heads 7, for example, by adopting
such a configuration.
[0054]
In addition, in the recording apparatus 1 according to the
embodiment, the ejecting unit-driving substrate accommodating
unit 20 and the control substrate accommodating unit 19 are
connected using the connecting portions 38 and 39 as the
16
connector terminal. For this reason, it becomes a
configuration in which workability when bonding the ejecting
unit-driving substrate accommodating unit 20 and the control
substrate accommodating unit 19, and detaching thereof is
improved.
[Second Embodiment] (Figs. 10 to 13)
[0055]
Subsequently, a recording apparatus according to a second
embodiment of the invention will be described.
[0056]
Fig. 10 is a front perspective view which schematically
illustrates a sub-carriage 5 in the embodiment, and corresponds
to Fig. 7 which illustrates the sub-carriage 5 according to the
first embodiment. Fig. 11 is a side perspective view which
schematically illustrates the sub-carriage 5 in the embodiment,
and corresponds to Fig. 8 which illustrates the sub-carriage
5 of the recording apparatus 1 according to the first
embodiment. In addition, Fig. 12 is a side perspective view
which schematically illustrates a carriage 6 which includes a
fixing portion 43 which can be adopted in a carriage 6 in the
embodiment. Fig. 13 is a schematic perspective view of a part
of the sub-carriage 5 in the embodiment.
[0057]
In addition, constituent elements which are common to those in
the first embodiment are denoted by the same reference numerals,
and detailed descriptions thereof are omitted.
[0058]
The recording apparatus 1 in the embodiment is different from
the recording apparatus 1 in the first embodiment only in a
configuration of the carriage 6.
[0059]
As described above, the carriage 6 (sub-carriage 5) according
to the first embodiment includes the ejecting unit-driving
substrate accommodating unit 20 which accommodates the
recording head 7 and the driving substrate 40, and the control
17
substrate accormnodating unit 19 which accormnodates the control
substrate 41.
[0060]
Meanwhile, as illustrated in Figs. 10 and 11, the carriage 6
(sub-carriage 5) according to the embodiment is provided with
an ejecting unit accommodating unit 37 which accormnodates the
recording head 7, and a driving substrate-control substrate
accormnodating unit 36 which accormnodates the driving substrate
40 and the control substrate 41. In addition, similarly to the
carriage 6 in the first embodiment, the fixing portion 21 and
the load absorbing unit 42 are provided. For this reason, in
the recording apparatus 1 according to the embodiment, it is
possible to suppress an application of a load to the recording
head 7 from the driving substrate 40 side, in the carriage 6
with a configuration of including the ejecting unit
accommodating unit 37, and the driving substrate-control
substrate accormnodating unit 36.
[0061]
As illustrated in Figs. 10 and 11, the driving substrate 40 and
the control substrate 41 in the embodiment are connected
through a flexible flat cable (FFC) 22, in the inside of the
driving substrate-control substrate accommodating unit 36. In
addition, the driving substrate-control substrate
accommodating unit 36 and the ejecting unit accormnodating unit
37 are connected, using a connecting portion 44 (connector
terminal) on the driving substrate-control substrate
accommodating unit 36 side, and a connecting portion 45
(connecter terminal) on the ejecting unit accommodating unit
37 side.
[ 0062 J
In addition, as illustrated in Fig. 10, the fixing portion 21
in the embodiment has a configuration of fixing a position of
the driving substrate 40 with respect to a position of the
recording head 7, by screwing the driving substrate-control
substrate accommodating unit 36 to the ejecting unit
accommodating unit 37. Meanwhile, as illustrated in Fig. 12,
18
a configuration may be adopted, in which a position of the
driving substrate 40 with respect to a position of the recording
head 7 is fixed, by fixing the driving substrate-control
substrate accommodating unit 36 to a position which is a part
of the carriage 6 other than the ejecting unit accommodating
unit 37, using the fixing portion 43, instead of a configuration
of using the fixing portion 21 in the embodiment.
[ 0 0 63]
In addition, as illustrated in Fig. 13, in the ejecting unit
accommodating unit 37 according to the embodiment, a hole
portion 48 is formed in the fixing portion 21. As illustrated
in Fig. 13, it is a configuration in which the recording head
