Paper holding mechanism and printing device using the paper holding mechanism

Abstract

The invention discloses a paper-holding mechanism and a printing device using the paper-holding mechanism. The paper-holding mechanism includes a frame, a paper inlet located on the frame, and a paper-holding rubber roller arranged at intervals from the paper inlet, wherein , the paper-holding rubber roller includes a driving roller and a driven roller tangentially matched with the driving roller, wherein a paper-holding opening is formed between the driving roller and the paper inlet, and the paper-holding mechanism also includes: a paper pressing frame, and a frame The flexible connection has a paper pressing part, wherein the paper pressing frame has a switchable initial position and a working position, wherein, when the paper pressing frame is switched to the working position, the paper pressing part forces the paper to bend into the paper holding space through the paper holding opening. According to the paper holding mechanism of the present invention, the paper is bent into the paper holding space under the pressure of the paper pressing part during the paper holding, which avoids the problem that the printing paper blocks the paper inlet when holding the paper. Therefore, the paper holding mechanism provided by the present invention high reliability.

Description

technical field [0001] The invention relates to a paper holding mechanism and a printing device using 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 process. Documents cause equipment failure, or recycle the printing paper forgotten b...

Problems solved by technology

[0006] The inventors have found that when the use environment is humid, since the printing paper is easy to adhere to the paper-holding upper channel plate 32' or the paper-holding lower channel plate 33' of the paper-in path P, the paper-holding rubber roller 31' When the printing rubber roller 12' drives the printing paper R to continue moving along the paper-feeding direction after stopping the rotation, the printing paper R may not bend toward the paper-holding opening D, but accumulate at the paper-holding opening D, thus blocking the paper-feeding port

Further, since the printing paper is usually a roll paper with a certain degree of curvature, if the printing paper bends toward the paper-holding opening D, when the paper-holding rubber roller 31' drives the printing paper R to move along the unwinding direction, the printing paper will The paper tail of R may directly cross the opening D of the paper container due to bending, and enter between the upper channel plate 32' for the paper container and the lower channel plate 33' for the paper container, which will also block the paper inlet. Therefore, this paper container mechanism is reliable. Low sex
