機本体から排出されるようになっている。In the figure, 1 is a large-capacity paper feed stacker that stores 1,000 to 3,000 sheets of paper, and 2 is an upper paper feeder that stores 200 to 500 sheets of paper. The paper is sent out from either the upper or lower paper feed section by the paper feed roller 3A or 3B, is pressed against and clamped by the synchronous roller 4 which has stopped rotating, and is pressed and rotated in synchronization with the rotation of the photoreceptor drum 5. Thereafter, the toner image is transferred to the paper by electrophotographic transfer, and then the paper is sent to the fixing device 7. Here, the toner on the paper is heated and fused and fixed onto the paper. Thereafter, the paper is selectively transferred to a tray 9, a sorter 10, or a double-sided copying device (not shown) by a conveyor belt 8, and then discharged from the main body of the copying machine.

位に達し停止する。When replenishing paper P in the paper replenishing section 20 or replacing it with another paper, first move the paper storage section 20 placed on the moving section of the loading table 4° to the stop position on the right side of the copying machine. Pull it out. Next, when the lowering button is pressed, the motor M1 of the elevating member 50 is driven and rotated, and the elevating table 57 is lowered to the lowest position. Therefore, the receiving plates 22 and 30 in the paper storage section 20, which are placed on the lifting table 57 by their own weight, simultaneously descend to the lowest position and stop.

げ部２２Ａ。Next, open the lid 26 of the paper storage section 20, and then open the movable side plate 26.
4.25 swings upward together with the lid 26, leaving most of the sides of the sheet stack open. In this state, place the paper stack to be replenished on the pedestal 31, and place the side edge of the paper stack on the fixed side plate 2.
2. The part 22A is inserted along the inner wall surface of 23 to regulate the position in the paper width direction, and further bends the leading end (paper feeding direction side) of the paper bundle.

端に接して用紙束を正確に位置決めする。When the paper replenishment is completed, the lid body 26 is closed. At this time, the movable side plates 24.25, one end of which is fixed to the support member 28 that is slidably attached to the lid body 26, swing around the rotation axis at the top of the fixed side plates 22.23, and have an inclination angle. The guide surfaces 240, 25G regulate and align both ends of the paper stack, and the paper side edge regulating surfaces 24B and 250 contact both ends of the paper stack to accurately position the paper stack.

が給紙される間は繰返し続けられる。As the paper is consumed, the upper roller 61 in contact with the paper descends, and when it is detected that it has reached a predetermined height, this detection signal causes the motor M1 to rotate again. As a result, the lifting platform 51 and the receiving plate 31 rise. When a predetermined height is reached, the motor M1 stops rotating. This operation continues to be repeated while the paper is being fed.

。During the rising process of the receiving plate 30, the rear surface regulating member 32 is held against the receiving plate 30 by the holding force of the permanent magnet 36.
and rise at the same time (No. 61 ◎→■). After the upper end corner portion 32A contacts the inner wall surface of the lid body 26 in the fixed position, the upper end corner portion 32A moves horizontally along the inner wall surface of the lid body 26 as the receiving plate 32 rises. The rear regulating member 32 slides and moves to the right, and while being held by the magnetic force of the permanent magnet 36, it tilts clockwise around the rotational shaft 34 (Fig. 6 ■→■→■→■→ ■Uh.

。Or, if you want to use one paper tray for various sizes of paper, use the above method! In addition to making it possible to move and set the llI temporary 22, 23, 24° 25, various receiving plate units 30 are prepared for each paper size, and when storing the necessary paper, a dedicated receiving plate unit is placed inside the outer box. It is also possible to carry out replacement loading. In this case, the receiving plates of the various receiving plate units have substantially the same shape as each paper size, and a rear surface regulating member having substantially the same shape as described above is rotatably attached to this receiving plate.
また、前記側板２２．２３も固定式とせず、後面規制部
材と同様の可動型構造としてもよい。Further, the side plates 22 and 23 may also be of a movable structure similar to the rear surface regulating member instead of being fixed.

皆無となる効果がある。[Effects of the Invention] As described above, the paper feeding device according to the present invention allows the paper storage section to be removed from the elevating member, and further lifts and lowers the receiving plate on which a large number of sheets of paper are placed to be stored in the paper storage section. The configuration allows the member to move up and down freely, and the rear surface regulating member that regulates the rear end of the paper bundle on the receiving plate is swingable relative to the receiving plate, so that the process of raising or lowering the receiving plate by the elevating member In this case, the position of the rear end of the sheet bundle is regulated by a rear surface regulating member. Therefore, the paper bundle does not collapse. In particular, there is an effect that there is no accident in which the upper layer of the paper bundle is shifted by the paper feeding member or the like, or it is turned up and the trailing edge of the paper goes over the rear surface regulating member, causing paper feeding failure.
