Pressure roller actuating mechanism for a printer

A printer includes a stationary paper chute (10) extending along the outer peripheral surface of a platen (1) over a limited angular extend thereof so as to define therebetween a paper feed passage. The paper chute (10) has an opening through which a pinch roller (11) is movable into and out of the...

Zusammenfassung:A printer includes a stationary paper chute (10) extending along the outer peripheral surface of a platen (1) over a limited angular extend thereof so as to define therebetween a paper feed passage. The paper chute (10) has an opening through which a pinch roller (11) is movable into and out of the paper feed passage for releasably locking paper onto the platen (1). The printer further has a pinch roller actuating mechanism which includes a pressure spring (12) disposed adjacent to the paper chute (10) for pressing the pinch roller (11) against the plate (1). The pressure spring (12) is composed of a cantilevered resilient strip having a free end on which the pinch roller (11) is rotatably supported, and a release camshaft (13) rotatably disposed between the paper chute (10) and the pressure spring (12) and angularly movable to resiliently displace the pressure spring (12) in a direction to move the pinch roller (11) away from the platen (11).
