Abstract
PURPOSE:To manually operate pressure contacting boards freely, by releasing the clutch within a prescribed period when the manuscript pressure contacting member is at locations where the pressure contacting is performed or not performed and when the member is rotated from a location where the pressure contacting is not performed to a location where the pressure contacting is performed. CONSTITUTION:When a motor 14 starts its working by a copy signal from the main body 1, a clutch 21 also starts to move simultaneously and starts to close a frame member 9 and a pressure contacting board 3. When opened, the pressure contacting borad 3 is self-standing by means of a spring action, but, when it is closed, the borad tends to drop from a point due to the self-weight. However, when the driving power of the motor 14 is cut and a braking power is applied throught a means, such as DC impression, to the board at the point from where the board starts to drop, the closing speed of the pressure contacting board becomes slow and the board will stop easily when it touches a manuscript table 2 or a manuscript. When the pressure contacting board is to be opened, the motor 14 is reversely rotated when the rear end of the copy signal is detected and the clutch is moved, and the pressure contacting board is opened. When the board reaches its self-standing position, the clutch is released.
