It is very crucial, the problem of control is forbidden pressure word and null occurs.Control paper driving unit motion can not occur step-out or
Person's leapfrog, in case there is the phenomenon of pressure word or null in the content for occurring printing.The problem of if there is step-out, then print
Paper out has the phenomenon of pressure word, that is, scattered multiple points can be beaten together, if there is leapfrog, i.e., wishes originally
Hope what is made a move, but actually motor has walked two steps or multistep, occurs in the middle of the content printed under such circumstances
Null.
Impact printer is the printer that domestic printing increment tax reciept is specified, if there is print quality it is poor the problem of, meeting
The influence of very severe is produced to user.
Utility model content

Two capable transmission rubber roll components.
It is further used as being provided with the improvement of technical solutions of the utility model, print enclosure body and is located at two transmission rubber roll components
The release handle of top, one end of release handle is operating side, and the other end of release handle is provided with a pinch roller for compressing paper, and pinch roller is eccentric
In a rotary shaft, print paper is adjusted by rotating the gap between the adjustable pinch roller of release handle and transmission rubber roll component
The number of plies.
The improvement of technical solutions of the utility model is further used as, an indicator, print enclosure are coaxially additionally provided with pinch roller
Body is provided with the dial for indicating paper sheet thickness or the number of plies.
The beneficial effects of the utility model：This impact printer drives pinion unit to act by paper driving unit so that
The transmission rubber roll component that is engaged with pinion unit rotates to carry out paper feeding, while by the code-disc that is rotated with paper driving unit to walking
The paper feed step number that altar reaches is counted, and when step number is inconsistent in being instructed by the paper feed contrasted with initially setting, drives paper feed
Motor compensates action, the problem of step-out or leapfrog can be effectively solved in paper driving unit real work, so as to reach higher
Printing precision.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the utility model embodiment overall structure schematic internal view；
Fig. 2 is the utility model embodiment overall structure front view；
Fig. 3 is the utility model embodiment overall structure top view.
Embodiment
1~Fig. 3 of reference picture, the utility model is a kind of impact printer structure, including printer housing 1 and installed in beating
The transmission rubber roll component 2 driven in print casing body 1 by pinion unit, is additionally provided with the paper feed for driving pinion unit 20 to act
Motor 3, paper driving unit 3 is provided with the code-disc rotated with paper driving unit 3 for counting, and paper driving unit 3 is stepper motor, printer
The top of housing 1 is provided with word car 4 and word vehicle and horse up to 5, and the both sides of printer housing 1 are provided with drive and are wrapped between two drives
Synchronous belt 51, drive and word vehicle and horse are up to being meshed transmission gear between 5.
Engaged between two drives and synchronous belt 51 by gear, the inner circumferential of synchronous belt 51 is provided around synchronization
The stepped tooth that the inner circumferential of transmission belt 51 is set.
This impact printer drives pinion unit 20 to act by paper driving unit 3 so that engaged with pinion unit 20
