Abstract

PURPOSE:To prevent damage to a hook part, etc., by providing a prohibiting means for prohibiting grasping a handle for drawing a carrying unit when a guide is closed, and for allowing grasping the handle when the guide is opened, in a paper feeding device constituted so as to draw the carrying unit. CONSTITUTION:A copying machine has a double surface unit 2 as a carrying unit forming part of a sheet carrying path, and a handle 7 is concealed by a main body 1 when the double surface unit 2 is closed. Opening carrying part covers 4 and 5 at the time of jam treating releases a lock device being locking the double surface unit 2 to make it show on a front surface to make the handle 7 provided on the upper surface of the double surface unit 2 appear. The lock device is constituted so that a locking part 8 can be released by a plunger, etc., when the opening of the carrying part covers 4 and 5, wherein the inner side is adopted as a carrying guide, is detected by a sensor; and the double surface unit 2 is pushed out by a spring 10 when locking is released.

2. Description of the Related Art A conventional example is shown in FIG.
After the fixing of the first side, the sheets are stacked in the two-sided duplex unit, re-fed for copying the second side, and discharged. This double-sided unit can be pulled out to the front for easy jam handling. However, if the jammed paper straddles the unit and the transport unit, when the unit is pulled out, the paper may get caught in the unit and the transport unit like a guillotine, complicating the jam processing. In order to remove the paper, the duplex unit is locked so that the duplex unit cannot be closed unless the covers of the transport units 4 and 5 are opened.
