Description

Printer device capable of correcting paper

The present invention relates to a printer device, and more particularly to a printer device capable of correcting paper.

Offices usually have printers with functions such as printing, photocopying or scanning, allowing employees to bring paper from external manual gates or internal paper trays into the machine for printing, photocopying or scanning. Wait for the word processing job, and finally send out the paper through the output tray.

However, when the above-mentioned printers are used, the paper is prone to skew or offset during transmission, causing skewed images in printing, photocopying, or scanning, or paper jams. Therefore, how to avoid paper skew or offset in order to achieve high-quality printing, photocopying or scanning images is the focus of the industry in improving printers.

In view of this, the inventor of the present invention focused on the above-mentioned prior art, and made great efforts to solve the above-mentioned problems, which became the goal of the present inventor's improvement.

The present invention provides a printer device capable of calibrating paper, which utilizes the paper to be inserted and restricted between two full paper stop arms, so that the printer device has the effect of calibrating paper.

After the processor 4 receives the paper size signal, it first drives the motor 321 to drive the drive gear plate 3211 to rotate to engage and drive the two transverse racks 322 to move outwards until the original point sensor 33 returns to the original point and outputs the return signal After the processor 4 receives the home signal, it controls the drive chain 3211 to engage and drive the two transverse racks 322 to move inward until the two entire paper stop arms 31 are retracted to the preset interval s, so the paper 100 is not fed. In the paper passage 12, the two entire paper stop arms 31 have been spaced to the preset interval s.

Finally, the paper 100 is conveyed from the paper feeding tray 11 to the paper feeding channel 12. When the paper 100 enters the paper feeding channel 12 through the paper input end 121, the two inclined guide pieces 311 are arranged on the left and right outer sides of the paper 100 and guide the paper 100. Gradually entering between the two paper stop arms 31, the two paper stop arms 31 are close to the width w of the paper 100 and attached to the left and right sides of the paper 100, so that the paper feeding channel 12 continues to transport the paper 100. The guide position of the second paper stop arm 31 is to prevent the paper 100 from skewing or offset, so that the printer device 10 can automatically determine the size of the paper 100, correct the position of the paper 100, have a simple structure, and improve printing, photocopying or scanning. The quality stability and other advantages.

In addition, the preset spacing s is between 1.01 to 1.015 times the width w of the paper 100. For example, the following is an example. If the width w of the paper 100 is 210mm, the preset spacing s is 212.1 (210*1.01) mm to 213.15 (210* Between 1.015) mm, the two paper stop arms 31 can accurately guide the position of the paper 100, and prevent the paper 100 from being excessively clamped, thereby increasing the service life of the printer device 10.

Furthermore, when the paper 100 is placed in the paper input tray 11, after the processor 4 receives the paper size signal, before the paper 100 enters the paper feeding channel 12, it can quickly control the interval between the two entire paper stop arms 31 to the preset interval s. The process of calibrating the paper 100 has the advantage of not affecting the printing, copying or scanning speed, and the two inclined guides 311 guide the paper 100 gradually into the two full paper stop arms 31, which can prevent the paper 100 from being impacted and causing scars to achieve The printer device 10 has the feature of supporting high-speed printing, photocopying or scanning.
