FILM PRESSING SYSTEM OF A CAPTION PRINTER

摘要

Disclosed is a film pressing system of a caption printer, in which a pressing plate (23) operated by a driving force of a motor (50) presses a film (70) onto a copperplate (80) having a caption embossed thereon, so that the caption is automatically and uniformly imprinted on the film. In the film pressing system, a roll ring (24) and an eccentric cam (31) are mounted on a side of the actuator (20), and a rotation shaft (32) is integrated with the eccentric cam. The roll ring (24) and the eccentric cam (31) are in rolling contact with each other at their circumferences, and the rotation shaft (32) is rotated by the motor (50) so that the eccentric cam is rotated about the rotation shaft. The actuator (20) is descended when a peripheral portion of the eccentric cam (31) more distanced from a center of the eccentric cam is in contact with the roll ring (24) to push the roll ring.
