ABSTRACT:
A housing (1) includes an upper tray (7) for receiving sheets which are not to be stapled, a lower tray (8) for receiving sheet stacks (35) which are stapled and an inclined tray (29) arranged in between and adapted for collecting and stapling sheets. The collecting tray (29) is arranged in a relatively steeply inclined position with respect to a stapling station (39) located at its lower end so that sheets entering the collecting tray (29) slide under the sole action of gravity automatically down to a movable blocking member (33) which limits the collecting tray (29). The collecting tray (29) is part of an assembly unit (13) which comprises all transport and guiding elements for feeding the sheets which enter an entrance area (5) either to the upper tray (7) or the collecting tray (29). Moreover, the assembly unit (13) supports all means required for producing sheet stacks and feeding out the finished sheet stacks. The assembly unit (13) is mounted on the housing (1) by means of lower stationary housing pins (59) and is fixed precisely in position by locking means (63, 64).
