Count unit 61A
　coating removing apparatus 10 includes a count portion 61A that counts the number of coating removal (see FIG. 3). In this embodiment, the count unit 61A is configured by the control unit 61 may be configured with a mechanical counter.
[0054]
　Figure 6 is an explanatory view of the counting process of coating removal times of the first embodiment.
[0055]
　In the first embodiment, the count unit 61A determines whether or not to detect the closed state of the lid sensor 51 of the detection result based heating side lid 23 (S101). Counting unit 61A, unless by detecting the closed state of the heating-side lid 23 (NO in S101), and repeats the determination process in S101 to detect the closed state of the heating-side lid 23. Counting section 61A when it detects the closed state of the heating-side lid 23 (YES at S101), then detects the separated state of the heating unit 20 and the gripper 30 based on the detection result of the separation detecting section 52 and it determines whether or not (S102). Counting unit 61A, unless detects the separated state of the heating unit 20 and the gripper 30 based on the detection result of the separation detecting section 52 (NO in S102), the flow returns to the determination process of S101. Counting unit 61A is, (YES in S102) when detecting a separation state between the heating unit 20 and the grasping unit 30 on the basis of the detection result of the separation detecting section 52, one is added to the count value of the count coating removal (S103) .
[0056]
　That is, in the first embodiment, the count unit 61A detects the closed state of the heating-side lid 23 based on the detection result of the cover detection unit 51 (at S101 YES), and, on the detection result of the separation detecting section 52 when detecting a separated state of the heating portion 20 and the grip portion 30 on the basis of (YES at S102), 1 single adds the count value of the count coating removal (S103). Thus, as shown in FIG. 2C, in the state in which the operator closes the heating-side cover portion 23 and the grip-side lid 33, to move the gripper 30 to the rear side with respect to the heating unit 20, a heating unit 20 when allowed to separate the gripping portion 30 (when the coating end of the optical fiber has been removed), it is possible to a count value indicating the number of times the coating removal is incremented by one. In the present embodiment, the count unit 61A will be stored a count value in the storage device.
[0057]
　As the addition condition of the count value, not only to detect the separated state of the heating portion 20 and the grip portion 30 (S102), it attempts to locate the closed state of the heating-side lid 23 (S101) becomes a condition ing. Therefore, when the "open state" of a heating-side lid 23, also detects the separated state of the heating portion 20 and the grip portion 30, the count value is not added. This is because, as shown in FIG. 2C, when separating the heating portion 20 and a grip portion 30 for coating removal, in order to state the operator closes the heating-side cover portion 23 and the grip-side lid 33 is there. As in the present embodiment, by that detects the closed state of the heating-side lid 23 (S101) is added condition count value, that the count value is increased when not removing the coating can be suppressed, it is possible to improve the counting accuracy of the count coating removal (consistent accuracy between the coating removal times and the count value).
[0058]
　In this embodiment, the count unit 61A, after adding the count value one 1 (S103), (YES at S105) when detecting the open state of the heating-side lid 23, the count of the subsequent coating removal times (S101 allow ~ S103). That is, in the present embodiment, after the count value is incremented by 1 (S103), (YES at S105) unless after detecting the open state of the heating-side lid 23, the count of the subsequent coating removal times row not us. This, after removal of the covering from the end portion of the optical fiber as shown in FIG. 2C, in order to remove the covering of the end of the next optical fiber, the heating-side lid to take out the optical fiber obtained by removing the coating part 23 (and the grip-side lid 33) and there is a need to open. Further, after removing the covering from the end portion of the optical fiber as shown in Figure 2C, the heating-side lid 23 (and the grip-side lid 33) without opening and thus it counts again the number of times coating removal, coating there is a high possibility of detecting the removal count erroneous.
