Description

ABSTRACT:
The paper feeding mechanism in a printer has a paper feeding roller and a pressure roller cooperating with the paper feeding roller so as to feed a paper sandwiched therebetween for the printing operation of the paper, and the pressure roller is mounted on a resiliently energized swingable lever so that the pressure roller is releasably urged against the paper feeding roller for feeding the paper. The paper feeding mechanism further comprises a paper arresting member adapted to disengageably contact with and arrest the paper when actuated, an actuating lever coupled with swingable lever as well as the paper arresting member and a driving solenoid provided with a plunger actuated thereby and coupled with the actuating lever. The relative arrangement of the swingable lever and the paper arresting member with respect to the actuating lever is so determined that, when the latter is actuated by the solenoid through the plunger thereof, the swingable lever is urged so as to move the pressure roller apart from the paper feeding roller for inactivating the feeding of the paper while the paper arresting member is actuated so as to arrest the paper.
