Abstract
PURPOSE:To make it easy to obtain an alarm signal for unphotographable parts by cooperating the resetting of a counter to a position S cooperatively with the removal of a patrone in a camera which prewinds a film and performs photographing by rewinding the film by each frame. CONSTITUTION:While a patrone 35 is not loaded, a counter reset lever 48 turns counterclockwise and a switch 47 and a counter driving gear 20 are held disengaged from a counter. A counter plate is held reset to the position S. When the patrone is loaded, said reset lever turns clockwise. When a rear cover is closed and a motor 1 winds a spool 13 fully after this, the counter indicates the number of photographing sheets, and subtracts the frames by each on at every rewinding of the film on account of photographing. When the remaining number of films decreases, a switch operating plate 22 operates the switch 47, thereby giving an alarm. In spite of the occurrence of an accident in which the rear cover opens on the way, the counter operates normally.
