PURPOSE:To automatically cut off a power source after feeding of prescribed film length despite turning off of a power switch when the execution of photographing operation is stored in a storage means which stores whether the photographing operation was executed or not after turning on of the power switch by providing said means. CONSTITUTION:A flip-flop F1 which stores the operation state of a loop detecting switch 234 and a flip-flop F2 which stores the operation state of a shutter switch S8 are provided to an automatic stop controlling mechanism. When a power switch S1 turns off upon ending of photographing, the flip-flop F2 is held reset, an AND gate G4 is held closed, and a relay RL2 remains on, thus the power source is kept supplied to the entire device. The power supply is automatically cut off after at least the film part of the final tail is developed after the detection of the minimum of the film loop by the loop detecting swtich 234 and measurement of prescribed film feed length by a counter 410. |
