Paper delivery device and printer

Abstract

The invention provides a paper delivery device and a printer. The paper delivery device is arranged on a paper outlet of a paper feeding channel of the printer; and an inlet part of the paper deliverydevice is connected with the paper outlet of the paper feeding channel of the printer. The paper delivery device comprises a paper feeding rubber roller, a paper feeding rubber roller motor and a first sensor, wherein the paper feeding rubber roller is arranged on an inlet position of the paper delivery device and is connected with a central processing unit (CPU) of the printer; an output shaft of the paper feeding rubber roller motor is in drive connection with the paper feeding rubber roller and is used for driving the paper feeding rubber roller to rotate so as to output printing paper sheets; and the first sensor is connected with the CPU of the printer, is arranged on an outlet part of the paper delivery device, and is used for detecting paper sheet state information of the outlet part of the paper delivery device, generating a feedback signal according to the paper sheet state information, sending the feedback signal to the CPU of the printer so as to enable the CPU of the printer to trigger the paper feeding rubber roller motor to reverse according to the feedback signal to recover the paper sheets on the outlet part of the paper delivery device. The printer is prevented from getting stuck by paper, and the user information is protected, so that the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a paper output device and a printer. Background technique [0002] With the continuous growth of self-service equipment such as high-speed rail and finance, how to ensure the operation of self-service equipment more efficiently and reduce maintenance costs has become the main requirement of users. The printer in the self-service equipment is easy to be forcibly pulled by the user during the process of outputting the printed paper after printing, resulting in deformation, loss of printed content, and error reporting by the printer. In addition, if the user does not take the printed receipt in time, it is easy to Errors that cause paper jams in printers and user information leakage. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a paper output device and a printer, which can prevent the printed paper from being forcibly pu...
