PURPOSE:To perform the operation accurately and easily by changing the speed of a motor in accordance with the resistance value outputted from an operating member whose resistance value is changed in accordance with the strength of a depressing force. CONSTITUTION:When a feeding top key 15R is depressed strongly, the resistance value outputted from a pressure-sensitive sensor 17R is reduced, and a high power is supplied from a control circuit 16 to a motor MR, and the feeding motor MR is rotated in a high speed. When the key 15R is depressed weakly, the resistance value is increased, and a low power is supplied from the control circuit 16 to the motor MR, and the rotative speed is reduced. When a rewinding top key 15L is depressed strongly, the resistance value outputted from a pressure-sensitive sensor 17L is reduced, and a high power is supplied from the control circuit 16 to a motor ML, and the rewinding motor ML is rotated in a high speed. When the key 15L is depressed weakly, the resistance value is increased, and the rotative speed of the rewinding motor ML is reduced. Thus, rotative speeds of the feeding motor MR and the rewinding motor ML are changed by the control circuit 16 to make a fine adjustment within a low-speed range possible, and a large quantity of film is fed in a short time. |
