PURPOSE:To detect replacement of a master without requiring a power source even at a power-off time by providing an arm part, which is shifted between two positions, on a shaft rotated at the master replacement time. CONSTITUTION:Arm parts 10 and 11 which are shifted from the initial position to a specific position by rotation of a shaft 8 are provided on the shaft 8 which is rotated by a lever 9 operated at the master replacement time, and a switch 12 is arranged in this specific position. The switch 12 is turned on when arms parts 10 and 11 reach the specific position by rotation of the shaft 8, and the switch 12 is turned off when arm parts 10 and 11 are returned to the initial position by rotation of drums 5 and 6. Switching information of this switch 12 is displayed on a display part of a copying machine body to report master replacement to the external. |
