The continuous paper 3 is moved in the width direction according to the width of the margin portion.

The burster unit 20 cuts the continuous sheet 3 into unit sheets at perforations formed in advance on the continuous sheet 3, and the front rubber roller unit 21, the burst roll unit 22, and the like along the transfer direction of the continuous sheet 3. The rear rubber roller portion 23 is sequentially arranged.

In the front rubber roller portion 21, an upper front rubber roller 21 a arranged so as to be movable up and down is in contact with the lower front rubber roller 21 b by its own weight, and the upper front rubber roller 21 a and the lower front rubber roller 21 b are the same as the pin tractor 24. Rotates at high speed. In the rear rubber roller portion 23, an upper rear rubber roller 23a disposed so as to be movable up and down is disposed with a small gap between the upper rear rubber roller 23a and the lower rear rubber roller 23b. It rotates at a faster peripheral speed than the front rubber roller portion 21.

When the sheet feed amount measured by the encoder reaches a predetermined feed amount set in advance according to the vertical dimension of the unit sheet, the perforation of the continuous sheet 3 corresponds to the burst roll unit 22. At this time, in the front rubber roller portion 21, the upper front rubber roller 21 a is pressed against the lower front rubber roller 21 b via the continuous paper 3 by pressing means (not shown), and in the rear rubber roller portion 23, the upper rear rubber roller 23 a It is pressed by the lower rear rubber roller 23b through the continuous paper 3, and the paper is nipped.

Then, the rear rubber roller portion 23 rotates at a faster peripheral speed than the front rubber roller portion 21, and as a result of the relative speed difference between them, the continuous paper 3 between the front rubber roller portion 21 and the rear rubber roller portion 23. When the burst roll unit 22 comes into contact with the perforations of the continuous paper 3, the continuous paper 3 is cut at the perforations.

Simultaneously with this cutting, the front rubber roller portion 21 and the rear rubber roller portion 23 move back to the initial state, and the cut unit paper is discharged by the rear rubber roller portion 23 to the intermediate transport portion 5 in the paper discharge storage device 1. The Further, the subsequent continuous paper 3 is transferred by the front rubber roller portion 21, and the above-described operation is repeated.

The configuration of the continuous paper processing device 2 in the present invention shown in FIG. 1 is different from the configuration of the conventional continuous paper processing device 60 shown in FIG. 4 in that the paper discharge roller 27 for discharging the cut paper from the device main body. The basic configuration of the other apparatus main body is the same. In the continuous paper processing apparatus 2, the intermediate transport unit 5 plays a role as discharge means for discharging the cut paper from the apparatus main body.

Can be dropped to the paper receiver 11 while maintaining a substantially horizontal posture without drooping. Therefore, the occurrence of jam can be prevented.

(Paper receptacle)
FIG. 2 shows a state in which the discharged paper P is stacked on the paper receiving portion 11, and a stopper 31 for abutting and aligning the paper is provided at the front end of the paper P in the paper discharge direction. The stopper 31 can be adjusted in installation position in the paper transport direction according to the size of the paper to be discharged.

The sheet discharged from the intermediate conveyance unit 5 while being curved in a U-shaped arc is dropped toward the paper receiving unit 11 provided downstream of the intermediate conveyance unit 5. The paper receiver 11 is inclined downward from the intermediate transport unit 5 in the paper discharge direction F. Thereby, the paper discharged from the intermediate conveyance unit 5 can be smoothly delivered to the paper receiving unit 11.

In addition, an interference member 18 that interferes with the discharged paper from above is provided in the course of the paper discharge path that is discharged from the intermediate transport section 5 to the paper receiving section 11. Thereby, it is possible to maintain a curved state in a U-shaped arc until the discharged paper is landed on the paper receiving portion 11. Further, as shown in FIG. 1, the thin plate-like elastic member 19 having one end fixed to the interference member 18 is arranged to be inclined in the paper discharge direction F, thereby maintaining the curved state in the U-shaped arc. The effect is further improved. A plurality of the thin plate-like elastic members 19 may be arranged on the interference member 18.

As shown in FIG. 2, one end on the upstream side in the transport direction of the interference member 18 is supported by one end on the downstream side in the transport direction of the arm member 14 of the intermediate transport unit 5. The other end of the interference member 18 on the downstream side in the transport direction is supported by a support portion 37 in the notch 39 of the support member 38.

As shown in FIG. 3, the paper P that has fallen on the paper receiving portion 11 in the paper receiving portion is curved in a V shape (U shape) along the cross-sectional V shape of the paper stacking portion 32, while the paper P The sheets are stacked on the loading unit 32 in an orderly manner. Accordingly, it is possible to increase the rigidity of the stacked paper P, and it is possible to prevent stacking defects such as wrinkles on the paper P during the stacking process.
