ABSTRACT:
In a collecting tray (1) having a lateral limiting member (6) and an end-side abutment (3), a driven aligning wheel (16) is arranged on a pivotally mounted, spring-biased tube (9 and 10 respectively). The abutment (3) is pivotally mounted on an arm (3a) and connected with a lever (4) which includes a pin (4a) adapted to support tube (9). When abutment (3) is pivoted to its opening position, aligning wheel (16) is lifted off sheet stack (24) so that the stack can be removed unimpededly. The aligning wheel (16) is conically shaped and pivotable from a position in which it is spring-biased towards the lateral limiting member (6) to a position directed at the front abutment (3) such that when a sheet has been laterally aligned, aligning wheel (16) is caused by the increasing friction to pivot in opposition to its spring bias to the position direction at the front abutment (3). The peripheral surface (16a) of the conical aligning wheel (16) is disposed such that an incoming sheet (7) first contacts the smaller diameter thereof and, sliding along the surface, is guided below aligning wheel (16).
