ABSTRACT:
A device for separating sheets of a recording medium has a feed head (22) that, together with feed rollers (58), lies on the top sheet of a horizontally arranged stack of the recording medium. The feed rollers (58) push the top sheet against a rising incline, so that its leading edge is lifted up and separated from the stack. The feed head (22) is arranged on an arm (18) that is designed to swivel freely on a swiveling plane that is parallel to the plane of the incline. In the feed head (22), the feed rollers (58) can move away from the incline parallel to the plane of the stack against the spring force.
