PURPOSE:To grasp whether a camera is in a photographable state or not, and to remove malfunction, by providing a means for detecting that the first film has been fed out after mounting a film cassette to the camera, and a means for raising an alarm in accordance with said means. CONSTITUTION:A roller 22 in a camera body 10 is connected to a motor 24, and also, for instance, is connected to a film counter 26 by which a numeral is displayed through the window provided on the camera body 10. The film counter 26 is reset when an opening and closing cover 14 is opened, and whenever one sheet of film is fed out, a count value is increased by 1 each. A reset switch 28 is closed only when the film counter 26 has been reset, by a partial projection of the numeral panel of the film counter 26. A detection switch 30 is closed when a film cassette 16 is mounted and is pushed mechanically by a part of the casing. A sounding member can be used by changing to an alarming light emission diode 34 provided on the outside wall of the body 10. |
