ABSTRACT:
An apparatus for facilitating depositing copy sheets in a collecting bin (6, 15) which, in the sheet entry direction, is arranged in a downwardly inclined position and is provided with a stop member (14) associated with the leading portion of the sheets. The trailing portion of the sheets is associated with guide element (19, 30) directing the incoming sheets onto the top of the sheet stack already deposited. Above the sheet stack (23, 23a) rollers (22, 26) are arranged which are driven in sheet entry direction and associated with the trailing portion of the sheet and whose surface area facing the sheet stack (23, 23a) lines beneath the entry plane of the sheets defined by the guide elements (19, 30) to the extent that also in the case of curled sheets it confines the top of the sheet stack (23, 23a) in a position beneath the sheet entry plane keeping the feed path open. The rollers include stationary rollers (22) associated with a first guide element (19) and rollers (26), pivoted parallel to rollers (22), associated with a second guide element (30) and in the pivotal path of the first guide element (19). The guide elements (19, 30) can be selectively moved to a position in which they extend upward beyond the sheet stack (23, 23a) so as to form a ramp.
