Abstract
PURPOSE: To warn the user for erroneous use of the camera to prevent an accident, by controlling the alarm operation through a film detection switch, a back cover opening and closing detection switch, a rewinding button switch, a rewinding rotation switch, and so on.
CONSTITUTION: Film detection lever 4 brought into contact with small-diameter part 2 of spool 1 is rotated clockwise by the upper end part of the loaded film, and film detection switch 7 connects respective switches, which are connected in parallel, and alarm circuit 30 through interlocked lever 6. Consequently, when back cover 34 is opened with the film loaded, cover 34 is opened for closing and locking of cover 34. Back cover opening and closing detection switch 10 is closed before opening, and alarm tone is issued from speaker 33. Similarly, when the push button is operated through rewinding rotation switch 11 and rewinding button switch 21 to start the erroneous rewinding operation before prevention of inversion of the sprocket, alarm tone is issued. Thus, erroneous use is warned to prevent accidents.
