ABSTRACT:
In an apparatus for the feeding of individual sheets (1) into office machines (2) in which the individual sheets (1) form a stack (3) of sheets atop which rotatively-driven fixed delivery rolls (4) rest and from which individual sheets (1) can be drawn over separating corners (5) of a paper-receiving frame (6), the stack (3) of sheets lies on a spring-action swing plate (8) between lateral paper-guide frames (7a, 7b). The invention provides for selectively alternative use, for supporting the sheet stack (3), of either the fixed paper-receiving frame (6) or of a separate and additional paper cassette (12) which is engageable with the machine (2) such that the spacing between the separating corners (30) on the cassette (12) and the circumference of the delivery rolls (4), when the cassette is mounted on the machine (2), is the same as the normal spacing between the separating corners (5) on the paper-receiving frame (6) and the circumference of the delivery rolls (4).
