Paper output mechanism, printer comprising same and terminal device

Abstract

The invention discloses a paper output mechanism, a printer comprising the same and a terminal device. The paper output mechanism comprises a machine frame, a rotating plate and a paper tearing knife, wherein the rotary plate is arranged on one side of a conveying channel of printing paper, one end of the rotary plate is connected with the machine frame through a pivot, the other end of the rotary plate is suspended, and the rotary plate is forced to rotate around the pivot in the first direction when the printing paper is pulled by external force. The paper tearing knife is fixedly arranged on the rotating path of the rotary plate which is provided with a notch, and when the rotary plate rotates in the first direction, the paper tearing knife stretches out of the notch and makes contact with the printing paper to tear the printing paper open. According to the paper output mechanism, the printing paper can be immediately torn open when the printing paper is pulled, and the problems that the printing effect is affected and paper is blocked due to the fact that the printing paper is deflected by pulling are solved.

Description

technical field [0001] The invention relates to the field of printers, in particular to a paper output mechanism, a printer and a terminal device with the paper output mechanism. Background technique [0002] Self-service terminal equipment has been widely used in various fields, such as automatic teller machines, telephone charge self-service inquiry machines, etc. The self-service terminal usually has a printing device, such as an automatic teller machine that can print transaction vouchers, and a call charge self-service inquiry machine that can print call charge details, etc. At present, the common problem of this kind of self-service terminal equipment with printing function is that if the user pulls the printing paper being printed during the printing process, it is easy to cause the printing paper to be skewed, thereby affecting the printing effect, causing paper jams, or due to continuous drawing out of the printing paper. The printing paper used causes the waste of...

Problems solved by technology

At present, the common problem of this kind of self-service terminal equipment with printing function is that if the user pulls the printing paper being printed during the printing process, it is easy to cause the printing paper to be skewed, thereby affecting the printing effect, causing paper jams, or due to continuous drawing out of the printing paper. Printing paper used, resulting in waste of printing paper

[0004] The problem with this solution is that if someone pulls the paper during the printing process, it will take a certain amount of time from when the sensor detects that someone pulls the paper and sends out a detection signal, to when the automatic cutter cuts off the printing paper, so the action of pulling the paper will last for a while. There is still a high possibility that the printing paper will be pulled off, and there may still be problems that affect the printing effect and cause paper jams
