PURPOSE:To alarm the slight remaining of a film by engaging a switch with a counter member in a camera which prewinds the film and performs photographing by rewinding the film by each frame. CONSTITUTION:A counter dial 23 is formed in one body with a switch plate 22 and a gear 21, and is driven by a counter gear 20 provided to the gears in a film feed system. while a patrone 35 is not loaded, a counter reset lever turns counterclockwise and disengages the gear 20 and therefore the gear is held stopped in the position S. When the film is loaded, the counter gear and a switch 47 abut on the gear and a cam 22. The counter indicates the number of frames that can be photographed in accordance with the prewinding. In the photographing state, the counter subtracts the frames by each one, and when the remaining number of the frames decreases, the switch 47 is closed by the crest parts 22a, 22b of the switch operating cam, and temporary alarming by a lamp, etc. is accomplished. |
