当る衝撃で移動することがない。 After the above operations are completed, when the copy button is pressed, the image is copied onto recording paper fed from the primary paper feeding means 2 in the copying section 4 in synchronization with scanning of the original. and,
The recording paper 3 that has been copied on one side is fixed, passes through the movable guide plate 10, and passes through the transport path 13 to the secondary paper feeding means 1.
7 will be transported. As a result, the recording paper is sandwiched between the friction wheel 19 and the double-feed prevention roller 20, which can rotate freely when the friction wheel 19 is rotating in the direction of arrow b', and the stacker 26
contained within. The stored recording sheets are correctly aligned by the width regulating member and the leading end regulating member, which are moved to positions that match the size of the recording paper, as described above. In this case, since the gear 54 meshed with the gear 53 fixed coaxially with the driving pulley 31 is locked by the locking means 57 when the tip regulating member 25 is not driven, the tip regulating member 25 cannot be moved by the impact of the recording paper hitting it. There is no.

moves upward to press the uppermost layer of the recording paper 3 against the friction wheel 19, so that the recording paper is sequentially fed out starting from the uppermost layer.

As explained above, the double-sided copying apparatus according to the present invention includes a movable leading edge regulating member for regulating the leading edge of the recording paper, and a movable width regulating member for guiding both sides of the recording paper from both sides. In the provided sheet stacking device, a driving source that drives the leading edge regulating member and the width regulating member, respectively, a first actuating means that drives the leading edge regulating member from the driving source, and a driving source that drives the width regulating member from the driving source. a switching means for selectively connecting the first actuating means and the second actuating means to the drive source; and a switching means for selectively connecting the first actuating means and the second actuating means to the drive source, and when the operation of the tip regulating member is completed. A locking means for locking the first actuating means, and a structure such that when the locking means locks the first actuating means, the second actuating means and the driving source are connected. As a result, the recording paper leading end abutting member provided on the floor of the stacker does not move due to the impact of the recording paper, and therefore the recording paper can always be correctly aligned in the stacker, making it easy to refeed. It has the excellent effect of making paper easier to handle.
