Novel seal printer

Abstract

The patent relates to a novel seal printer. A jet nozzle is driven to rotate and carry out print through a motor in a printer shell. The number of parts in the printer is reduced, the size of the printer is the same with that of a traditional seal, and the replacing of the traditional seal is realized. At the same time, a coaxial connecting device is arranged in the printer, the structure is simple, and a certain coaxiality difference tolerance is available. The printer is simple to mount and durable.

Description

technical field [0001] The invention relates to a portable printer, in particular to a novel stamp printer. Background technique [0002] The official seal is the seal for a legal person to handle internal and external affairs, and only documents with the official seal have legal validity. In order to improve the efficiency of stamping, etc., in recent years, a stamp printing system has been developed in the existing technology, that is, a printer is used to print the stamp, which has the advantages of fast printing speed, clear printing effect, labor cost saving, and can cooperate with the computer system to realize anti-counterfeiting Functions and other advantages, more and more widely used. [0003] However, there is currently no printer dedicated to printing seals, and current printers can only print files with electronic seals attached, that is, seals and files are printed together, and the printer can print any content. Restrictions; the printing effect is generally...

AI Technical Summary

Problems solved by technology

[0003] However, there is currently no printer dedicated to printing seals. Current printers can only print files with electronic seals attached, that is, seals and files are printed together, and the printer can print any content. There is no monitoring and control of the use of the printer and the control of printed content. Restrictions; the printing effect is generally ordinary printing ink, but not the effect of printing oil; therefore, the current printing can only be regarded as the audio and video output of the file, not the stamping of the file

[0004] In short, there is no special stamp printing equipment at present, so a dedicated stamp printer with small size, controllable process, and stamping effect is needed; however, most of the existing stamp printing equipment is made of traditional printers or slightly modified. The printing equipment of this prior art has the following problems in use:

[0005] 1. It takes up too much volume and needs to be connected to the power cord during use, which does not have the portability advantages of traditional seals at all;

[0006] 2. It needs to be used with the paper feeding mechanism, and the paper feeding mechanism needs to cooperate with the position of the printing nozzle, which makes it difficult to adjust the printing position of the stamp, and it is impossible to affix the stamp at different designated positions at any time like the traditional stamp;

[0007] 3. The traditional parallel printing method is often used, that is, the print head moves along two vertical coordinate axes or only in one direction in the plane. This printing method generally requires multiple back and forth strokes to complete, which is time-consuming and energy-consuming. Low efficiency; In addition, due to the structural design of traditional printers, traditional parallel printers have the problem that the outer edge of the printed circle is not round enough. When the print head travels horizontally on the paper surface, there will be visible errors at the seam between the current stroke and the next stroke. , that is, a ladder-like pattern;

[0008] 4. The irregular structure of the existing ink cartridge can affect the volume of the entire printer, making the structure of the entire printer bulky and clumsy
