ABSTRACT:
A film transport indicator for a camera with a motor drive includes a film transport signal generator for generating a film transport signal in response to a film being wound by the motor drive, a quasi-signal generator for generating a signal analogous to the film transport signal, and a switching circuit for passing said film transport signal when it is generated by said film transport signal generator and for passing the signal from said quasi-signal generator for a prescribed period of time when said film transport signal is ceased. The feeding of the film is indicated on an indicator unit in response to the signals having passed through the switching circuit.
