<p>PURPOSE:To constantly effect stable registration independently of the friction, conveying speed, etc. of paper, by detecting the conveying speed of the paper to keep the deflection of the paper constant. CONSTITUTION:The outputs of a Hall integrated circuit HIC1 and a photosensor PS1 for detecting the paper are processed through inverters IN1, IN2. The outputs of Hall integrated circuits HIC2, HIC3 and photosensors PS2-PS4 are received. An interface unit 11 supplies output signals to a conveying solenoid SOL1 and an electromagnetic clutch MC through driving transistors Tr1, Tr2 and also supplies output signals to another conveying solenoid SOL2 and paper feed solenoids SOL3, SOL4.</p> |
