Abstract

The invention relates to an improvement of a structure of an opening device of a printer cover. The invention provides an opening device which facilitates opening and closing the cover, and is long in service life and not easy to damage. The device comprises a machine body. A buckling cover is arranged above the machine body. The device is characterized in that one end, located on the front side surface of the machine body, of the buckling cover is articulated with a first rod; a curve hole is formed on one side, farther away from the front side surface of the machine body, of the buckling cover and internally provided with a sliding shaft; the sliding shaft is connected with a second rod; a straight hole is formed in the first rod and internally provided with a sliding rod; the sliding rod is arranged and fixed on the machine body; a lower cover is arranged on the surface of the machine body; and the end part of the second rod is fixed on the lower cover.

Description

technical field [0001] The invention relates to an improvement of the structure of a printer cover opening device. Background technique [0002] A printer (Printer) is one of the output devices of a computer, which is used to print the results of computer processing on related media. There are three indicators to measure the quality of a printer: printing resolution, printing speed and noise. There are many types of printers. According to whether the printing element hits the paper, it can be divided into impact printers and non-impact printers. According to the structure of printing characters, it can be divided into full-size character printers and dot-matrix character printers. According to the way a line of characters is formed on paper, it can be divided into serial printers and line printers. According to the technology adopted, it is divided into printers such as cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, and light-emitting diode. [...
