ABSTRACT:
A motor-driven camera of the prewind type arranged to perform a preliminary film winding action continuously from an automatic film loading onto a take-up spool before photographing and, thereafter, to rewind the film for every photographing shot includes an electric film counter arranged to count the number of frames of the film according to the transport of the film, a detecting device for detecting the movement of the film, and a detecting circuit which detects a cause for the immovable state of the film when the detecting device has detected the immovable state of the film. The detecting circuit is arranged to determine the preliminary film winding action to have been completed when a counted value of the electric film counter is greater than a predetermined value, or to determine the automatic film loading to have failed when the counted value is not greater than the predetermined value.
