PURPOSE:To imprint characters at specific character intervals by detecting the feed position of a film and imprinting data corresponding to the feed speed. CONSTITUTION:A control circuit 10 generates a high-level signal MOTOR when a motor 11 is driven, and a transmitting means 13 transmits the power of the motor 11 to the winding device of the camera. Furtaer, detectors 13 and 14 for film movement generate a signal PCK when the film is moved. Then, the signals MOTOR and PCK are inputted to an imprinting timing generating means 15, which generates and inputs a signal TCK to an LED turning-on circuit 6. The circuit 6 turns on LEDs when the signal TCK rises and the terminal CLK of a shift register group 4 goes up to a high level every time the LEDs turn on once to shift data successively. |
