Various automatic paper feeding devices that employ vacuum suction methods have been proposed in the past, and one example is the Jikosho paper feeder.
An automatic paper feeder as seen in No. 43-19279 is known. This device consists of a suction cup device, a protruding piece as a separating claw, and a presser roller that prevents the rear end of the film from being lifted up.It can separate the film to a certain extent, and also If the film gets over the protrusion and is separated, it has the advantage of being able to be returned to its normal position by the presser roller, but since the presser roller is placed above the film, it may interfere with the film setting operation. However, the drawback was that it was inconvenient.

があつた。 In addition, a suction device and a separating claw are used in combination, and at least two pieces of photosensitive paper are suctioned and held by the suction device.
The present applicant has already filed an application for an automatic paper feeder (Japanese Patent Application Laid-Open No. 19243/1983) which rotates and moves up and down to feed paper. However, even in this type of device, the paper feed table is pushed up by a spring force and the paper feed side edge of the topmost photosensitive paper is pressed against the separation claw, so there is no difference between when there are many sheets of photosensitive paper and when there are few. There is a drawback that the force with which the photosensitive paper is pressed against the separating claw varies greatly, which affects the separating operation, and as a result, the number of sheets of photosensitive paper that can be set is limited. In addition, when the suction device is moved up and down at least twice, the photosensitive paper held under suction is lowered to its original position before suction and brought into contact with the second sheet of photosensitive paper, so that there is a vacuum between the two photosensitive papers. There was a drawback in that when the suction device returned to its normal state and began to move upward again, the second and subsequent sheets of photosensitive paper were sucked up. In addition, in the structure of the paper feed tray described above, the suction device may suck and hold the photosensitive paper in a undulating state to adversely affect the sorting operation, but in this case, wrinkles will occur when feeding the paper to the feed roller. There were many shortcomings.

The present invention has been developed in view of the above-mentioned points, and the separating claw is arranged above the maximum stacking height of photosensitive paper, and the suction element that holds the photosensitive paper by suction is placed above the maximum stacking height at least twice. With an extremely simple structure in which the photosensitive paper is shaken off in the vertical direction and the photosensitive paper is struck from below against the separating claw,
To provide an automatic paper feeding device for a copying machine that can reliably handle and separate photosensitive paper and prevent simultaneous feeding of a plurality of sheets of photosensitive paper.

い部位Ｐより離れた状態になる。 The suction element 23 is held at a predetermined height above the paper feed side end 2a of the photosensitive paper 2 (first
Fig. 4 (a). At this time, the roller 13 is pressed against the portion of the cam surface 16a of the paper feed cam 16 farthest from the shaft 17, and holds the suction element 23 at the uppermost position A in FIG. When the paper feeding operation is started in this state, the paper feeding cam 16 begins to rotate clockwise in FIG.
is rotated clockwise in FIG. 1 by the force of the spring 15. Therefore, the fulcrum shaft 12 and the arms 19, 20 also rotate integrally with the lever 14 to lower the adsorption element 23, and the roller 13 moves onto the cam surface 1.
When the position P closest to the axis 17 of 6a is reached, the suction element 23 contacts the uppermost photosensitive paper 2A and holds the photosensitive paper 2A by suction (state shown in FIG. 4B). Here, although the support shaft 22 is rotatable relative to the arms 19 and 20, since the roller 30 of the cam lever 31 rises along the cam surface 34 of the guide cam 33, it is rotated counterclockwise in FIG. , Accompanying this, the adsorption element 23 moves slightly backward. Further, the point at which the photosensitive paper 2 is attracted by the adsorption element 23 moves from point M to point N as the number of sheets of photosensitive paper 3 decreases, with the maximum stacking height being L (see FIG. 3). When there is a large amount of photosensitive paper 2, the suction element 23 is restricted by the photosensitive paper 2 during the time from point M to point O, and therefore stops at that position. At this time lever 14
The roller 13 is located further away from the portion P of the cam surface 16a that is closest to the shaft 17.

下の感光紙を確実に落下させることができる。 Adsorption element 2 sucking and holding the top photosensitive paper 2A
3, as the paper feed cam 16 rotates, the roller 13 rides over the two bumps A and B on the cam surface 16a, thereby moving vertically twice to shake off the photosensitive paper. This shaking-off action may occur if you accidentally lift multiple sheets of photosensitive paper by suction.
The second and subsequent sheets of photosensitive paper are separated from the top photosensitive paper 2A and dropped. During this shaking-off operation, the photosensitive paper that is being held under suction is lifted up to the position shown in Figure 4C and placed in the handling claw 8. It was hit from below and lowered to the position shown in Figure 4 D. Note that points Q and S in the third figure indicate that when the roller 13 rides on the tops of the bumps A and B, points R and T fall into the valleys P 1 and P 2 of the cam surface 16a (see figure 1). Indicates the hour position. As is clear from this cam diagram, the suction element 23 performs the swing-off operation twice above the maximum loading height L, so when it descends to points R and T, the photosensitive paper that is being suctioned and held is not fed. There is no contact with the photosensitive paper on the stand, so there is no vacuum state between the photosensitive papers, and the second and subsequent sheets of photosensitive paper are prevented from being sucked up when the suction element 23 rises again. Furthermore, even if multiple sheets of photosensitive paper are held up by suction and lifted, the photosensitive paper will be shaken off twice and hit against the claw 8, and at the same time the side edge of the photosensitive paper will be removed as shown in FIG. Separate the parts with claws 8
Since the photosensitive paper 2A is curved, a gap is created between the first photosensitive paper 2A and the second photosensitive paper 2B, forming an air layer. Therefore, the separating effect is large, and the second and subsequent sheets of photosensitive paper can be reliably dropped.

移動させることにより行なわれる。 When the photosensitive paper shake-off operation is completed, the suction element 23 is lifted to its original uppermost position as shown in FIG. This feeding operation is performed by the roller 3 as the arms 19 and 20 rotate upward.
0 rises along the cam surface 34 of the guide cam 33, the cam lever 31 rotates clockwise in FIG. 1, and the suction element 23 is moved in the direction of the paper feeding rollers 35 and 36.

ば何回でもよいことは勿論である。 In the above embodiment, the photosensitive paper shaking operation of the adsorption element 23 is performed twice, but the present invention is not limited to this, and it goes without saying that the shaking-off operation can be performed any number of times as long as it is performed twice or more. .

As set forth above, the automatic paper feeder for a copying machine according to the present invention moves the suction element, which holds the photosensitive paper under suction, in the vertical direction at least twice above the maximum loading height to place the photosensitive paper against the picking claw. Since it is configured to perform a sorting operation, the sorting effect is great,
The photosensitive paper on the paper feed stand is not sucked up during the shaking-off operation of the photosensitive paper, and the photosensitive paper can be separated and fed more reliably. Therefore, it is possible to prevent an accident in which multiple sheets of photosensitive paper are fed out one on top of the other, and since the structure is simple and no rollers are used for sorting, there is no risk of damaging the photosensitive paper. , its practical effects are very large.
