a magazine unit (3) having a magazine (30) in which a staple bundle (11) consisting of staples connected to each other is loaded, and supported on the other end portion-side (20b) of the clincher unit (2) to be rotatable about a fulcrum shaft portion (22) as a fulcrum with respect to the clincher unit (2);
a driver unit (4) having a driver (42) configured to strike out a staple from the magazine (30) and provided on one end portion-side, the other end portion-side of the driver unit (4) being supported to be rotatable about the fulcrum shaft portion (22) as a fulcrum with respect to the clincher unit (2); and
a handle unit (5) connected to the driver unit (4) by a transmission shaft portion (6) provided between the fulcrum shaft portion (22) and the driver (42), and configured to move the driver unit (4) toward the clincher unit (2) for opening and closing;
wherein the magazine unit (3) has:
a pusher (31) provided to be movable along a length direction of the magazine,
a pusher spring (33) for pressing the pusher (31) toward a magazine (30) front wall part of the magazine (30), and
a pusher band (34) having one end portion attached to the pusher (31) and the other end portion attached to the driver unit (4), and configured to connect the pusher (31) and the driver unit (4), and
wherein in a state where the pusher (31) is retreated by the pusher band (34) and is moved to a most retreat position in an operation of opening the handle unit (5) and the driver unit (4) with respect to the clincher unit (2) and the magazine unit (3),
characterized in that a length between an inner surface-side of the magazine front wall part (30b) and the pusher (31) is 75mm or longer,
a length of the magazine (30) is 90mm or longer and 100mm or shorter,
a length of the pusher band (34) is 51mm or longer and 61mm or shorter,
a length from the fulcrum shaft portion (22) to an attachment position of the pusher band (34) to the driver unit (4) is 41mm or longer and 50mm or shorter, and
an entire length of the stapler (1A) is 105mm or longer and 125mm or shorter.

2. The stapler (1A) as claimed in Claim 1, comprising:
a camshaft portion (23) provided to any one of the clincher unit (2) and the handle unit (5); and
a cam groove portion (50d) provided to the other of the clincher unit (2) and the handle unit (4), configured to permit the camshaft portion (23) to enter, and having one open end portion in a direction, in which the clincher unit (2) and the handle unit (5) separate from each other, to enable the camshaft portion to be inserted/pulled out.

3. The stapler as claimed in Claim 1 or 2, wherein a ratio of the length of the magazine (30) and the length of the pusher band (34) is 10:5.7 to 6.1, and
wherein a ratio of the length of the magazine (30) and the length from the fulcrum shaft portion (22) to the attachment position of the pusher band (34) to the driver unit (4) is 10:4.6 to 5.0.
