ABSTRACT:
A supply magazine (1) for a sheet stack (8) comprises a lower portion (2) which is open at the top and a cover (3) which covers the lower portion (2) at least in its sheet-removal area (roller 9) and can be opened. A pressure plate (4) pivotally mounted in the lower portion (2) is urged by springs (10) which spring-urge a sheet stack (8) arranged on the pressure plate (4) in the sheet-removal area against the inner side (3d) of the closed cover (3). As a result of the sheet stack (8) being pressed against the inner side of cover (3), it is so held by spring pressure that even if the supply magazine (1) is brought into an extremely inclined position during insertion into the copier or removal therefrom, the sheet stack (8) cannot be displaced and no sheets can drop out. With respect to the operative position of the supply magazine (1) in the copier, the distance of the pressure plate (4) from the inner side (3d) of the cover (3) is larger than the distance of the pressure plate from the operative area of the sheet-removal device (roller 9). As a result sheet stack (8) is lifted from the inner side (3d) of the cover (3) by an amount so that sheets can be separated without friction being exerted on them.
