Problems solved by technology

The overturning path part coincides with the paper feed position, and the overturned paper will fall on the new paper. Since the printed paper itself is easier to roll up, the printed paper will be placed on the separation wall, and then when the paper is rubbed, it will be rolled up at the same time. Rubbed into the printing path, so it is prone to refeed problems

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as Figure 1 to Figure 5 As shown, the double-sided printer in this embodiment includes a body 1, a paper box 2, a paper return passage 3, a partition 4, a paper pickup mechanism and a driving mechanism.

[0032] Wherein the carton 2 is installed in the body 1, and the installation position of the carton 2 in the body 1 is specifically set according to needs, such as the carton 2 in this embodiment is installed at the bottom of the body 1, and the carton 2 is usually placed in a detachable Installed in the machine body 1 and can be pulled out relative to the machine body 1 to place paper.

[0033] One end of the paper box 2 is connected to the paper feeding channel in the machine body 1 as the paper feeding end. In order to realize double-sided printing, the machine body 1 in this embodiment also has a paper return channel 3, and ...

Abstract

The invention relates to a double-sided printer. The double-sided printer comprises a printer body, a paper box, a paper returning channel, a partition plate and a paper rubbing mechanism, wherein the paper box is installed in the printer body; the paper returning channel is arranged in the printer body; the partition plate is rotationally connected to the printer body, is located above the paper box and is connected with the paper outlet end of the paper returning channel; and a first paper rubbing wheel used for rubbing paper above the partition plate is arranged at the first end of the paper rubbing mechanism, a second paper rubbing wheel used for rubbing paper in the paper box is arranged at the second end of the paper rubbing mechanism, and the paper rubbing mechanism is in linkage fit with the partition plate so that one of the first paper rubbing wheel and the second paper rubbing wheel can work. According to the double-sided printer, the paper which is printed on one side and returned can be isolated from the paper in the paper box, and then the problem that the paper is sent again when the paper is printed on the second side is completely avoided.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a duplex printer. Background technique [0002] In the existing double-sided printing technology, the paper printed on the first side will be returned to the carton for printing on the second side. However, after the paper is printed once, the paper will be rolled up to a certain extent, so when it is returned to the paper box for the second side printing, it is easy to cause the paper to be re-fed. [0003] For example, the Chinese invention patent "Printer and its double-sided printing mode control method" with the authorized announcement number CN1892465B (application number 200610094186.7), in which the disclosed printer has a printing path inside it in order to realize double-sided printing, along the a printing path that supplies the printing medium to a printing unit so that an image is printed on the first side of the printing medium; media is ejected from the printer ...
