Automatic device for matching document take-up speed to document feed-out speed in printer or copier
摘要
The device includes a sensor which detects the curvature of the document. The sensor provides an analogue and constant output signal, which is connected to a voltage controlled oscillator. The latter produces a constant variation of the drive frequency of the motor of the document feed-out device, based on the operation of the sensor's activation member.
