Abstract
PURPOSE:To prevent an original placing stand from slipping down despite unevenness of an upper body by providing the original placing stand driven by a driving wheel freely reciprocatively to the upper body, and locking said stand by a stop lever engaging to or disengaging from a ratchet cam of the driving wheel. CONSTITUTION:A notch 84 is formed to one side corner part of an original placing stand 72, and the top part of a stop lever 85 energized upward at all times by a tension spring 85a is meshed with this notch 84 and locked. A solenoid 86 is connected to the bottom end of this stop lever 85, and a detaining pawl 75 extended laterally is provided. This pawl 75 is meshed at all times with the ratchet cam 88 provided coaxially to a driving wheel 75, and while the cam 88 is held stopped to the pawl 87 by the clutch provided between the cam 88 and the wheel 75, the wheel 75 does not revolve, and the wheel revolves when the cam 88 is freed.
