PURPOSE:To prevent erroneous operations by detecting automatically the end of film to indicate the next film rewinding operation with a motor driving device. CONSTITUTION:When the number of frames which is count contents of a BCD down-counter 10 becomes zero, outputs of an inverter N116 and an inverter N134 becomes high-level together in a decoder, and therefore, the output of a NAND gate A130 becomes low-level, and the output of a NAND gate A101 becomes low-level. If a set camera is an adapted type, a type detecting switch S15 is turned on as it is, and the signal inputted to a NAND gate A102 is in the high level, therefore, the output of a NAND gate A104 attains to high-level, and picture and characters which instruct the user to set a camera rewinding member are displayed on a liquid crystal display device. When a clutch R of the camera rewinding member is set, a switch S17 of the clutch R is turned on, and the output of an inverter N106 becomes high-level, and picture and charac ters which instruct the user to set a motor driving device rewinding member are displayed. |
