Printer with improved pinch roller actuating mechanism
 A printer includes a stationary paper chute extending along the outer peripheral surface of a platen over a limited angular extent thereof so as to define therebetween a paper feed passage, the paper chute having an opening through which a pinch roller is movable into and out of the paper feed passage for releasably locking a paper on the platen. The printer further has a pinch roller actuating mechanism which includes a pressure spring disposed adjacent to the paper chute for biasing the pinch roller against the platen, the pressure spring being composed of a cantilevered resilient strip having a free end on which the pinch roller is rotatably supported, and a release camshaft rotatably disposed between the paper chute and the pressure spring and angularly movable to resiliently displace the pressure spring in a direction to move the pinch roller away from the platen.
