Printer paper feeding device based on light sensation control principle

Abstract

The invention relates to the technical field of computer auxiliary equipment, and discloses a printer paper feeding device based on a light sensation control principle. The printer paper feeding device comprises a shell, a lamp bead is fixedly connected in the shell, a photosensitive component is fixedly connected in the shell, a rotating shaft is fixedly connected in the shell, a first gear is movably connected outside the rotating shaft, an electromagnet is fixedly connected outside the first gear, a fixing shaft is movably connected outside the first gear, a clamping rod is movably connected to the fixing shaft, a ratchet wheel is movably connected outside a rotating shaft, and a gear is movably connected in the shell. Whether printing paper is located in a paper feeding groove or not can be sensed through the light sensing characteristic of a photoresistor, then whether the paper pushing function is triggered or not is determined, in this way, it is guaranteed to a great extent that the condition of printing content errors does not occur during printing, if paper jamming occurs, a printer can quit the printing paper immediately, and the device is more suitable for practical use.

Description

technical field [0001] The invention relates to the technical field of computer auxiliary equipment, in particular to a paper feeding device for a printer based on the principle of photosensitive control. Background technique [0002] There are many types of computer-aided equipment, including printers, scanners, mobile hard disk lights and some equipment, and the printer is one of the output devices of the computer, which is used to print the computer processing results on related media. There are three indicators to measure the quality of the printer. Items: print resolution, print 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. [0003] As a device that people use every day, printers are very effective in helpin...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a printer paper feeding device based on the principle of photosensitive control, which has the advantages of convenient paper feeding and automatic paper ejection, and solves the problems of printers during daily use.

[0007] Often due to the wrong position of the printing paper or the friction between the printing papers, the papers are dragged against each other, which may cause the printing paper to not be accurately aligned with the entrance of the printer, and paper jams may occur. Or the situation that the printing paper cannot be pulled out due to too much printing paper, which affects the use of the user
