ABSTRACT:
The present invention provides a camera enabling effective use of parts retrieved from a used lens-mounted film. Members retrieved from a lens-mounted film and responsible for film feed and release operation; such as, a sprocket, a sprocket axis with a charge cam attached, a drive lever, and a locking lever are mounted in a camera as they are. A release mechanism is included to release a frame stop state set for frame-by-frame film feed and a state in which the turn of a film wind knob is disabled, whereby film rewind is enabled. A strobe circuit board containing a strobe flashing unit and a control circuit is recycled for a camera permitting film rewind. In this case, a flashing capacitor mounted on the retrieved strobe circuit board is angled at lead wires so that the flashing capacitor can be placed in any state different from the one in a lens-mounted film. Moreover, electric connections for the retrieved strobe circuit board are made readily by adding coupling means having contacts and connecting the strobe circuit board to a battery via the coupling means.
