    摘要: The present invention is provided with a head pressing mechanism for pressing a thermal head against a platen, a paper feeding mechanism for feeding print paper between the thermal head and the platen in a secondary scanning direction, a ribbon transporting mechanism for transporting an ink ribbon between the thermal head and the platen in the secondary scanning direction, and a press releasing mechanism for causing the thermal head to move away from the platen against a pressing force of the head pressing mechanism. The press releasing mechanism slides a rod of a solenoid, elongated in the secondary scanning direction, at the position opposing to the rear surface of the thermal head in the secondary scanning direction. A lever link transforms this sliding action into the departing action of the thermal head from the platen. The solenoid and the thermal head are longitudinally aligned substantially in parallel to each other, and the area occupied by the thermal head and the solenoid is reduced, thereby resulting in a thermal printer which is compact as a whole.

    摘要: A can end double-seaming machine has a housing in which a shaft is rotatably supported. The shaft with a seaming cam lever mounted is pressed downwardly by a presser against the bias of a spring until the lower surface of the seaming cam lever is held against the upper surface of the housing. Then, an annular spacer is fitted over the lower end portion of the shaft underneath, with the tubular support held against a neck of the shaft. A seaming roll lever is then mounted on the lower end portion of the shaft. The presser is deactivated to release the shaft, which is lifted together with the seaming cam lever, the annular spacer, and the seaming roll lever under the bias of the spring until the marginal portion of the annular spacer abuts against the lower surface of the housing. The tubular support enters the housing by a distance corresponding to a predetermined clearance. The seaming cam lever and the housing are now spaced from each other by the predetermined clearance.

    摘要: A label printer for printing an image on a plurality of labels attached to a base sheet and issuing the labels on which the image has been printed. The label printer includes a platen roller, a pinch roller adapted to separably contact the platen roller through the base sheet, a slide frame for supporting the pinch roller so that the pinch roller is movable between a contact position and a separate position with respect to the platen roller, and a frame stopper for releasably holding the slide frame in the contact position where the pinch roller is in contact with the platen roller. When the frame stopper is released from the slide frame, the slide frame is slid to reach the separate position to widely separate the pinch roller from the platen roller. Accordingly, the base sheet can be easily inserted through the space defined between the platen roller and the pinch roller separated therefrom.
