Paper holding mechanism and printing apparatus with paper holding mechanism

Abstract

The invention discloses a paper holding mechanism and a printing apparatus with the paper holding mechanism. The paper holding mechanism comprises: a paper holding rubber roll, which is arranged in a printing paper transmission channel and includes a first roller and a second roller, wherein the first roller forms a paper holding opening with an end of a lower channel plate of the printing paper transmission channel which is located above the first roller; a turnover panel, which is pivoted with the first roller and forms a transmitted connection with the first roller, wherein the turnover panel possesses a connection state of connecting the paper holding opening and an open state of opening the paper holding opening. In the invention, the turnover panel forms a bridge connecting the lower channel plate and the paper holding rubber roll on the position of the paper holding opening; no matter whether printer paper is soft or crooked, the paper can smoothly entered into the paper holding rubber roll so that the printer paper is not stuck and plugged in the paper holding opening during a paper feeding process; contradiction between a paper holding opening arrangement size and the printer paper can be solved; reliability of the paper holding mechanism and adaptability to medium can be raised.

Description

technical field [0001] The invention relates to a paper holding mechanism used in an embedded printing device of self-service terminal equipment, and also relates to a printing device with the paper holding mechanism. Background technique [0002] Currently, self-service terminal devices with embedded printing devices are widely used in daily life. For example, in the telecommunications business hall, people use the self-service terminal equipment to inquire and print the call bill; at the bank self-service kiosk, people deposit and withdraw through the self-service terminal equipment and print transaction vouchers. [0003] In order to meet the special needs of self-service terminal equipment in public places, a paper storage mechanism is usually set between the paper outlet of the self-service terminal and the printing device to temporarily store the printing paper before the printing is completed, so as to avoid the user from pulling the printing paper during the printing...

AI Technical Summary

Problems solved by technology

[0006] In the printing device of the prior art, in order to ensure that the printing paper can be smoothly formed into a "U" shape and temporarily stored in the paper holding space C during the printing process, the size of the paper holding opening D should be large enough. The bending degree of the upper part is relatively large, and it cannot enter the paper-holding rubber roller 31 through the paper-holding opening D, but gets stuck between the paper-holding rubber roller 31 and the paper-holding lower channel plate 33, causing printing failure
