PURPOSE: To attain reduction in the cost of a camera and the simplification of constitution by providing a pulse generating means generating a pulse signal indicating the moving amount of a film accompanying with a roller member arranged at the perforation passing position of the film.

CONSTITUTION: The roller member 8 is arranged at the position where the perforation 9b of the film 9 passes in a state pressurized contact with the surface of the film 9. On the other hand, the pulse generating means 8a generates the pulse signal N indicating the moving amount of the film accompanying with the rotation of the roller member 8. When the film is fed, the output of the pulse generating means 8a when the roller member 8 is located on the surface of the film 9 is supplied as the recording instruction signal of information, and the output of the pulse generating means 8a when the roller member 8 is located on the perforation 9b of the film 9 is supplied as the positioning signal of a frame 9a. Thus, the camera is reduced in cost and the constitution is simplified.
