Paper storing device with a swingable engaging member and an engaging/detaching mechanism

摘要

In a paper feeding device, a paper feeding deck which moves back and forth is provided with a guide bar which extends in the direction in which the paper feeding deck moves and which has grooves formed in required portions corresponding to the sizes of recording paper sheets. A width aligning guide supporting member guided by the guide bar is fixed to a width aligning guide. The width aligning guide supporting member is provided with an engaging member detachably engagable with a groove of the guide bar. In addition, an engaging and detaching mechanism is provided for the width aligning guide supporting member. The engaging member is detachable from a groove of the guide bar by the engaging and detaching mechanism and then, the width aligning guide, along with the width aligning guide supporting member, can be moved to a position corresponding to the size of the recording paper sheets. The engaging member then is engaged with another groove of the guide bar by the engaging and detaching mechanism. Consequently, the width aligning guide is stably supported on the guide bar in a predetermined position.
