The stack loader (9) has a movable receiving member (31) with two slide compartments (35 and 36), wherein the receiving member serves as a movable intermediate tray whose slide compartments can be selectively aligned with the opening of the chute (37) and can be selectively loaded and unloaded again with an end slide (21, 24) of the stack of slides in one of the storage chambers (17 or 19) by a series of friction wheels (47, 49, 61, 63).
