Embodiment Construction

[0022] attached Figure 8 An implementation example of the present invention-a double guide post cover opening mechanism is described.

[0023] The structure of the implementation example of the present invention is composed of a button 1, a main body 2, a spring 3, a screw 4, a gasket 5 and the like.

[0024] The structure of the present invention is assembled like this: when the button is pressed down, the two ends of the button move down along the two guide posts through the guide bushing, and the locking mechanism is driven by the protruding part structure in the middle of the button to open the machine cover. The reset of the button is returned by two spring forces, and the fastening screw and the gasket are used to fix the spring.

[0025] The mechanism of the present invention works like this: the double cylinders on the main body guide the up and down movement of the key, and the double cylinders cooperate with the holes at the two ends of the key. The middle hole of...

Abstract

A cover opening mechanism for bill printer is composed of a main body with two longitudinal guide rods, spring sleeving on both guide rods respectively, and a key with two holes matched with said guide rods for allowing the key to move along them and a boss for triggering the lock unit to open the cover of printer.

Description

technical field [0001] The invention relates to a cover opening mechanism of a receipt printer. Background technique [0002] In the receipt printer, the printing paper is installed in the machine, and the cover needs to be opened when the printing paper is loaded and replaced. Therefore, it is necessary to design a cover opening mechanism. The disadvantages of component composition are: complex mechanism, high manufacturing cost, and large space occupation. [0003] The invention has simple structure and convenient manufacture. Installed on the receipt printer, it can ensure the smooth opening of the cover of the receipt printer. It forms an ingenious cover opening mechanism with the standard print head assembly. It is suitable for use on the receipt printer with a large space for the print head assembly. It is easy to use the plastic parts cleverly. The characteristics of manufacturing the guide post structure can reduce the manufacturing cost under the premise of ensuri...
