Copying machine for preventing copying paper from being contaminated by ink

Abstract

The invention discloses a copying machine for preventing copying paper from being contaminated by ink and relates to the field of electronic recording processes with charge patterns. The copying machine comprises an upper cover, a platen, a paper outlet, a first rotating shaft, a second rotating shaft, a third rotating shaft, a first connecting rod, a second connecting rod, a brush rod, chain poles, a chain, gears, a pedal and a chute, wherein the platen comprises an upper surface and a vertical surface; the paper outlet is horizontally formed in the vertical surface of the platen; the first rotating shaft is arranged at the boundary of the upper surface and the vertical surface of the platen; the vertical surface on which one end of the rotating shaft is located is the vertical surface ofthe paper outlet; the upper cover is also connected with the first rotating shaft; and the upper cover can completely cover the platen. By adopting the technical scheme of the invention, the requirement that the surface of copied paper has no excessive ink is met, the purpose that the copied paper is prevented from being contaminated by ink is achieved, and the copying machine is applicable to paper copying.

Description

technical field [0001] The invention relates to the field of electrical recording process equipment using electric charge patterns, in particular to a copier for preventing copy paper from being stained with ink. Background technique [0002] Most copiers use electrostatic methods to copy, so they are also called electrostatic copiers. It is a device that uses electrostatic technology to copy documents. Copiers are capable of making equal, enlarged, or reduced copies of written, drawn, or printed originals. The copying speed of the copier is fast and the operation is simple. The main difference from traditional type printing, stencil printing, offset printing, etc. is that it can directly obtain copies from the original manuscript without going through other intermediate means such as plate making. It is economical when the number of copies is small. [0003] When using a copier, it is necessary to place the copied original face down on the platen glass. The image of the o...
