A large force is applied to the leading end of the clincher guide 2
Since 10 is locked by the fixing plate 251, it is prevented from turning clockwise. Also, fixed plate 2
By making the angle of the inclined surface 253A of 51 small with respect to the horizontal, the clincher guide 210 can be reliably locked by the spring 260 having a small urging force.

By reducing the urging force of the spring 260, the size of the spring 260 can be reduced, and the leading end of the clincher guide 210 collides with the sheet bundle P when the spring 260 is released. The impact sound at the time of this collision can be reduced.

When the staple S1 is completely ejected from the ejection passage 601, the forming holder 110 is lowered by the rotation of the homing return cam 473 (time T9). When the forming holder 110 is lowered, the pushing of the bent portion 521 of the leaf spring 520 by the forming holder 110 is released. FIG. 2

When the clincher link 201 rotates counterclockwise to the position shown in FIGS. 64 and 65 with the lowering of the forming holder 110, the contact surface 202B of the clincher link 201 moves the shaft 33 further forward. Then, the first link plate 271 is moved to the position shown in FIG. 64 (time T14). The amount of forward movement of the first link plate 271 is determined by the distance L ₂ between the shaft hole 281 and the shaft hole 283.
There By is set to approximately twice the distance L ₃ between the shaft hole 281 and the shaft hole 282, it is about twice the amount of movement of the first link plate 271. For this reason, the first link plate 27
Even with a slight movement of 1, the fixing plate 251 can be largely moved, and the lock of the clincher guide 210 can be reliably released.

On the other hand, when the clincher link 201 rotates to the position shown in FIGS. 64 and 65, the support surface 203 A of the clincher link 201 pushes up the shaft 32, so that the clincher guide 210 moves the clincher arm 2.

Rotate clockwise around. Spring 26
Since the urging force of 0 may be small, the load on the motor M at this time is small.

When the driver 102 descends to a predetermined position as the driver folder 101 descends, the tip 512A of the anvil 512 enters the embossing passage 601 (time T14a).

Next, when the forming holder 110 is lowered to the home position (time T15), the driver holder 101 is also lowered to the position shown in FIG. 3, and the clincher link 201 is turned to the position shown in FIGS. . When the clincher link 201 comes to the position shown in FIGS. 52 and 53, the contact surface 20 of the clincher link 201
The shaft 33 comes off from 2B. Therefore, the shaft 33 moves rearward along the elongated hole 215 of the clincher guide 210 by the urging force of the spring 227. By the movement of the shaft 33, the clincher arm 220 rotates clockwise around the shaft 31 with respect to the clincher guide 210 and moves to the position shown in FIG.

The shaft 32 attached to the clincher guide 210 is engaged with the concave portion 254 of the fixed plate 251, and the shaft 33 is brought into contact with the contact surface 202 A of the clincher link 201 by the urging force of the spring 260. Then, the micro switch 29 detects the clincher link 201 which has reached the position shown in FIGS. 52 and 53, and the driving of the motor M is stopped.
