Abstract
PURPOSE: To keep contact pressure constant and surely supply sheets of paper one by one, by feedbacking to an electromagnetic actuator the difference between a prescribed level and the contact pressure which is applied to a paper supply roller by the electromagnetic force of the electromagnetic actuator.
CONSTITUTION: Sheets of copying paper stacked on an internal plate 3 in a deck body 1 are supplied one by one by a paper supply roller 10 which comes into contact with the top of the paper. The pressure of the contact is measured by a strain gauge provided on the arm 12 of a paper supply roller shaft 11. The measured pressure is compared with a level prescribed depending on the kind of the paper. The difference between the compared quantities is feedbacked to the solenoid 16 of an electromagnetic actuator. The actuator causes constant torque depending on an electrical current level proportional to the difference, to apply upwardly turning torque to the rotary shaft 5 of the internal plate 3 through a gear train 13 and a coupler.
