Abstract

PURPOSE:To obtain pressure contacting boards which easily and automatically opens and closes, by stopping the driving of the power supplying means at an intermediate time point and changing the driving into braking actions, when the manuscript pressure contacting member is rotated from a location where the pressure contacting is not performed to another location where the pressure contacting is performed. CONSTITUTION:When a motor 14 starts its working through a copy signal delivered from the main body 1, a clutch 21 also starts working simultaneously and starts to close a frame member 9 and a pressure contacting board 3. When opened, the pressure contacting board 3 is self-standing by means of a spring action, but, when it is closed, the board 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 through 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.
