Abstract
The present invention is related to a camera having a film wind spool with an insertion slot for receiving a film leader, a counter roller at a film supply side of the film wind spool, and a film winding device having a plate-shaped guide member between the film wind spool and the counter roller for guiding the film leader from the film supply side to the insertion slot of the film wind spool when the guide member is in a first position. The guide member further includes two end pieces, each of the two end pieces are pivotally connected to a different axial end of the counter roller. A rear cover is provided on the camera that opens to expose the film winding device and has an interior projection. The film winding device further includes a flange protruding from the film winding device in a position corresponding to the interior projection when the rear cover is closed. This flange is connected to one of the end pieces for moving the guide member from the first position to a second position which allows winding of the film onto the film wind spool when the rear cover of the camera is closed.
