Abstract
PURPOSE: To automatically select the speed of a film feed pawl driving motor at one of three defined speeds through combination of ON-OFF of two switches by providing two detecting switches which respond to the changes in the increase and decrease of film loop.
CONSTITUTION: A control circuit 19 which controls the speed of a film feed pawl driving motor M1 in photographing part consists of the speed defining circuits 19A, 19B, 19C which define the speeds respectively corresponding to the first speed 18 frames/second, second speed 20 frames/second, third speed 16 frames/second. These circuits automatically select the defined speed of the film feed pawl driving motor M1 from the three defferent defined speeds including one speed suited for silent photographing by the actuation of the first, second detecting switches SW1, SW2 which are started when the film loop formed between the photographing part and recording part becomes less or more than the specified loop amount range according to the change in the amount of said film loop as well as logic circuit 15.
