An apparatus capable of using a film cartridge in a manner that a lead portion of a film contained in the cartridge is fed out therefrom by the film thrusting, wherein a controller judges that an initial loading is not executed normally when a perforation is not detected although a fed film amount on an initial loading reaches a first predetermined amount, and stops a detector from detecting a perforation until the fed film amount reaches a second predetermined amount which is less than the first. Thus, a detector does not wrongly detect a notch on a film's lead portion as a perforation, and a leading frame is fed normally with a reliable judgment on an initial loading.

Apparatus capable of using a film cartridge containing a lead portion of

An apparatus in use of a film having information recording section, wherein a magnetic head is held with a head guide member which is disposed on a pressure holder, so that the magnetic head could be movable and rotatable in a perpendicular direction to a film plane. When an magnetic recording or reading is executed during a film feeding operation, the magnetic head may keep touching closely with a film plane, thereby an accurate magnetic or recording can be executed.

Apparatus in use of a film having information recording section

A control device for feeding and positioning a film precisely, in a camera, a printing apparatus, etc., includes a photo interrupter with a light emitter, a light detector for detecting a light emitted from the light emitter, and a holding member for keeping both the light emitter and the light detector in position; a frame with a guiding member for guiding a film having a longitudinal edge with a plurality of perforations which travels between the light emitter and the light detector of the photo interrupter; a perforation detector for detecting a perforation based upon a signal outputted from the light detector, which outputs the signal each time a perforation of the film edge passes a location corresponding to an optical axis existing between the light emitter and the light detector; and a controller for controlling a film feeding operation in accordance with the detection of a perforation by the perforation detector.
