ABSTRACT:
An UP/DOWN dial is used with at least one of switches including a back cover switch detecting whether the cover switch of the camera is opened or closed, so as to also serve as a switch for driving a feed motor by the manual operation. As a result, the number of switches can be reduced. That is, the switch for driving the feed motor by the manual operation is used only when the film is set in the camera (only when the back cover opens). Therefore, if the cover switch detects that the back cover opens, the UP/DOWN dial is operated regardless of the currently-set mode, so that the feed motor can be driven.
