Abstract

The invention relates to a cam-and-swing link combining control type micro-printer, which effectively solves the problem that the prior button-type opening mechanism is provided with a paper bin door which is difficult to open, and comprises a panel with a paper bin door, a casing body and a printing unit and a bracket of the printing unit assembled in the casing body, and a paper bin door opening device. The printer is technically characterized in that the cap of the button of the paper bin door opening device is exposed to the panel, the locking axle of the button pushes a sliding support which performs reciprocating motion along a slide way on the side wall of the bracket, to drive the toothed cam meshed with toothed bars on the sliding support to rotate, the cam part of the toothed cam is propped against the inner side of the large crank turn wall of a swing link, the outer sides of a larger crank turn wall and a small large crank turn wall which are assembled at both ends on the inner side of the paper bin door of the panel are positioned in an identical plane, contact the inner surface of the paper bin door of the panel. The micro-printer has the advantages that the transmission structural design is compact, the integrated control action is stable, the paper bin door can be flexibly and conveniently opened and closed, arbitrary position changing of the casing body can prevent the driving members from loosing and falling off, and the service performance and the service life of the printer are obviously improved.

Description

technical field [0001] The present invention relates to a kind of micro-printer suitable for various instruments and meters suitable for paper-tape data printing, especially a cam-swing-rod joint-control type with compact transmission structure design, stable joint control action, flexible opening of the paper bin door, and light weight. Micro printer. Background technique [0002] At present, various instruments and micro-printers of instruments and their printing units, ribbons, control circuit boards, and paper rolls for paper-tape data printing on the market have been standardized and generalized. The present inventor has been aiming at some defects existing in the existing micro-printers, and constantly improves them, and successively designs some brand-new micro-printers suitable for various places, such as "capacity-expanding micro-printers" with inclined supports (patent Notification No. CN2555156Y), an "expandable micro-printer" with an elastic connecting panel on ...
