It rotates counterclockwise (in FIG. 6) around 3 as a fulcrum. With this rotation, the clamp members 51 and 52 close, and the sandwiching plate 105 starts to bend.

On the other hand, the slider 34 returns to the original position. When the slider 34 returns to the original position, the pusher 103 of the cartridge 100
Of the holding room 101 in the storage chamber 101 is sent forward by one sheet. At this time, the cartridge body 1
Since the protruding portions 123 are provided inside the side wall 102A of 02, the holding plate 105 is sent out in front of the storage room 101 in a stable state without tilting.

When the clamp rotating members 53 and 54 further rotate counterclockwise with the rotation of the driving gear 85, the clamping plate 105 is further bent, and the sheet placed on the table 160 is further folded. The end of the bundle S is clamped.

Further, as the drive gear 85 rotates,
The clamp rotating members 53 and 54 rotate clockwise about the shaft 63, and the clamp members 51 and 52 rotate in the opening direction opposite to the above. And the driving gear 85
When the drive cam 90 makes one rotation, the clamp member 5
1, 52 return to the original position (see FIG. 6), and the operation of the drive mechanism stops.

In the above embodiment, the cartridge 100
Although the opening 107A is formed in the front wall 107, the opening 107A may not be formed. In this case, the slider 34 may be formed in a plate shape, and the plate-shaped slider may be directly inserted into the concave portion 108 of the cartridge 100.

The side plates 35 of the slider 34 are provided with protrusions 35A, 35B, and the protrusions 35A, 35B are provided with ridges 41, 41.
1 may be provided. Even in this case, even if the holding plate 105 is slightly deformed, only one sheet can be reliably pulled out from the cartridge 100.
