One-way loading paper printer case

Abstract

The invention relates to a unidirectional paper feeding type printer protective shell. The unidirectional paper feeding type printer protective shell comprises an integrated shell body; the lower portion of the shell body is provided with a load bearing frame used for placing a printer; a paper receiving plate is installed on the rear portion of the upper end surface of the load bearing frame in a hinged mode; a compressed spring is arranged between the lower end surface of the paper receiving plate and the load bearing frame; the middle of the rear end surface of the shell body is provided with a paper placing opening; vertical slide ways are arranged in the positions, located below the paper placing opening, of the inner side surface of the shell body; a slide strip is arranged in the vertical slide ways in a matched mode; a suspension arm fixed to the inner wall of the shell body is arranged below the vertical slide ways; a V-shaped bridge plate is installed at the inner end of the suspension arm in a hinged mode; and one end of the V-shaped bridge plate is located under the slide strip, and the other end of the V-shaped bridge plate is located under the rear portion of the paper receiving plate. According to the unidirectional paper feeding type printer protective shell, the paper receiving plate capable of automatically going up and down is used as a tool for storing paper and can flexibly drive the V-shaped bridge plate according to the paper storage amount, and the V-shaped bridge plate is used as a middle driving piece to control closing and opening of the paper placing opening, so that physical closed-loop adjusting of a paper feeding system and the unidirectionality of the paper feeding mode are achieved.

Description

technical field [0001] The invention relates to the technical field of printer equipment, in particular to a protective shell of a unidirectional paper-loading type printer. Background technique [0002] Printers are common office equipment, and cloud printers are a new type of Internet printing system that emerged under the requirements of modern office, that is, with the cooperation of the cloud system, the terminal printers and supporting computers or processors are used to selectively print documents. Out, the terminal's printer and other equipment need to be protected by a protective shell to prevent the terminal's printer from being illegally damaged. [0003] Since the printer is enclosed and installed in the protective shell, adding paper to the printer needs to open the protective shell frequently, which is inefficient and complicated to operate. However, the open paper feeding method can quickly add paper to the printer in the protective shell through the paper fee...

Problems solved by technology

[0003] Since the printer is sealed and installed in the protective case, the protective case needs to be opened frequently to add paper to the printer, which is inefficient and complicated to operate. However, the open paper loading method can quickly add paper to the printer in the protective case through the paper filling port. Add paper everywhere, but it also exposes the paper, which is not only easy to encounter illegal theft, but also easy to pollute the paper
