When the delivery plate 100 faces the negative sheet hanging plate 184 of the discharge section 28, it is moved in the direction of arrow B by the drive of the air cylinder 86. As a result of this movement, the pins 109 and 107 of the delivery plate 100 come into contact with the pins 194 and 196 provided on the negative sheet hanging plate 184, and are pressed in the direction B against the biasing force of the compression coil spring 204. At this time, the pins 198 and 200 are inserted into the through holes 16A and 16B provided in the negative sheet 12. From this state, the air cylinders 214 and 212 are driven, and the negative sheet pressing member 218 is moved downward into the groove 218B.
The hanging portion 12B is housed inside. This negative sheet pressing member 218 prevents the negative sheet 12 from moving in the direction of arrow C. Next, the supply of negative pressure to the suction cup 274 is stopped, and the negative sheet 12 is transferred to the delivery plate 100.
The held state is released. Further, when the delivery plate 100 is moved in the direction of arrow C by the drive of the air cylinder 86, the pins 109, l07 and the openings 18A, 1

Here, one side of the engagement pins 320 and 322 in the width direction (the side surface on the discharge part 28 side) comes into contact with the inner circumferential wall of the through hole 312 and 314, so that their rotational movement is restricted, and the rotational movement of the engagement pins 320 and 322 is restricted.
196 is prevented from rotating further from the state where it hangs down in the direction along the direction away from the support pins 308 and 310 (in the direction of arrow B in FIG. 23).
The engaging pins 320, 322 engage the negative sheet 12 which is about to move together with the pins 194, 196, and prevent the negative sheet 12 from moving together with the pins 194, 196 in the direction of arrow B in FIG.

Therefore, the negative sheet 12 is supported with the support pins 308 and 310 inserted into the through holes 16A and 16B, and the pins 194 and 196 are automatically pulled out from the through holes 18A and 18B of the negative sheet 12. The delivery is completed.

Thereafter, the above-described process is repeated, and the negative sheets 1°2 that have been moved to the discharge section 28 are automatically stacked on the original sheet stacking device 300.

After a plurality of negative sheets 12 are stacked on the original sheet stacking device 300, the rotary lenoid 326 is operated so that the engagement pins 320 and 322 are always aligned with the support pins 308 and 31.
The state can be set apart from 0. That is, when the rotating arm 328 rotates, it presses the upper end of the engagement pin 320, thereby pushing the engagement pin 32 in the direction of arrow C in FIG.
0.322 rotates and becomes separated from the support pins 308 and 310. In this case, when the engagement pin 320 rotates, its intermediate portion presses and operates the microswitch 330, thereby restricting the operation of the rotary lenoid 326.

When the engagement pins 320 and 322 are separated from the support pins 308 and 310, the plurality of negative sheets supported by the support pins 308 and 310 of the document sheet accumulating device 300
2 can be removed at once without any restrictions.

In addition, the pin 60.62.66.68.107 of the above example
