Abstract

PURPOSE: To prevent external light from leaking into a camera by detecting electrically and displaying the winding and rewinding states of a film.
CONSTITUTION: When a film winding switch 20 is turned on, a winding drive part 30 operates to wind the film by specific length. Simultaneously, a pulse generator 40 generates a pulse signal A, which is inputted to a display control part 50. At this time, it is decided from the phase of the signal A whether the film is wound or rewound. The control part 50 when detecting the winding state outputs a display switching signal B to a display drive part 60, which operates to make a winding display 80. When this winding operation is completed, a calendar and timer circuit 70 sends information on a photography date, time, etc., to the drive part 60, which makes a calendar to time display 80. This operation is carried out every time the film is wound. When a rewinding switch 90 is turned off, a rewinding drive part 100 operates and the display control part 50 detects the phase of the signal A and the rewinding or winding state, so that the display device 80 display the rewinding state through the operation of the drive part 60.
