Paper delivery device and printer with same

Abstract

The invention provides a paper delivery device which comprises a shell and a paper guide plate arranged in the shell. The paper delivery device is provided with a paper inlet and a paper outlet and comprises a lower paper arching plate which is articulated with one end of a paper inlet of the paper guide plate and an area above the paper inlet and the paper outlet of the paper delivery device and the lower paper arching plate is a paper delivery channel. Compared with the prior art, the paper delivery device has the beneficial effects that printing paper is delivered in a curve and the lower paper arching plate is arranged; when the curved printing paper is pulled to be a straight line approximately by a person, and the printing paper which is pulled to be straight applies a force to the lower paper arching plate to press the lower paper arching plate to swing, a swing signal is detected by a first sensor so that the printing paper delivery operation that the printing paper is pulled is judged and a treatment measure is taken in time to prevent the waste of printing paper and the damage to the printer.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a paper output device and a printer thereof that prevent artificial pulling. Background technique [0002] In the existing printer, during the printing process, the print head runs at a certain printing speed, and the printing paper runs at a certain speed. Existing printing environments are diverse, often due to various human factors, the speed of the printing paper will be too fast, for example: artificially pulling the printing paper, resulting in an instantaneous increase in the speed of the printing paper, causing a large amount of printing paper Pulling out causes waste, and at the same time, failures such as paper jams, deformation of printed characters, and damage to the printer occur. Contents of the invention [0003] In order to solve the above-mentioned existing technical problems, the present invention provides a paper output device, which uses a curved line to ...
