摘要
PURPOSE: To prevent a deviation in the position of a film, without increasing size and the cost by providing a means for feeding the film up to the position according to the perforation of the film, in a direction opposite to a fixed direction. ;CONSTITUTION: It is judged whether a main switch 2 is turned on or off. A lens barrel is extended from a collapsed position to a photographing possible position by a lens barrel driving circuit 8. Then, the film is unwound by 2 film driving circuit 11 and a first film position is detected by a perforation detecting circuit 7. Further, the second light signal of the perforation is detected during a fixed unwinding time, to stop the supply of power for unwinding the film. Then, the film driving circuit 11 is switched from the supply of the power for unwinding to that for winding, to wind the film and detect a second film position. The detection of the second film position is completed and the supply of the power for winding in the film driving circuit 11 is stopped. Thus, the deviation in the exposure position of the film is corrected.;COPYRIGHT: (C)1996,JPO
