Embodiment 1

[0051] An embodiment of the present invention, such as figure 1 As shown, the present invention provides a paper jam detection system for a cash register printer, which includes a printing paper bin, an auxiliary roller 1 , a rotation detection module 2 and a processor 3 .

[0052] The auxiliary roller 1 is arranged in the printing paper compartment, and is used for assisting paper feeding during printing. Specifically, the auxiliary roller 1 can guide and support the movement of the paper, the rotation speed of the auxiliary roller 1 is equal to the moving speed of the paper, and the rotation speed of the auxiliary roller 1 is constant when the printer is printing.

[0053] The rotation detection module 2 is connected with the auxiliary roller 1, and is used for collecting the rotation data of the auxiliary roller 1 when the printer is printing.

[0054] The processor 3 is connected with the rotation detection module 2, and is used for judging whether the cash register print...

Embodiment 2

[0058] An embodiment of the present invention, such as figure 2 As shown, on the basis of Embodiment 1, the rotation detection module 2 includes a magnet and a magnetic sensor.

[0059] The magnet is arranged on the auxiliary roller 1, and the magnetic sensor is arranged on the printing paper bin opposite to the auxiliary roller 1, for when the auxiliary roller 1 rotates, the magnetic field generated by the cutting magnet triggers an electromagnetic response; or, the magnetic sensor is arranged On the auxiliary roller 1, the magnet is arranged on the printing paper compartment opposite to the auxiliary roller 1; when the auxiliary roller 1 drives the magnetic sensor to rotate, the magnetic field generated by the magnetic sensor cutting the magnet triggers an electromagnetic response.

[0060] The processor determines whether the cash register printer has jammed paper based on the electromagnetic response.

[0061] Preferably, the magnet is a non-circular magnet, and the magn...

Embodiment 3

[0067] An embodiment of the present invention, such as image 3 As shown, on the basis of Embodiment 1, the rotation detection module 2 includes an angular velocity sensor.

[0068] The angular velocity sensor is fixed in the auxiliary roller 1 for collecting the angular velocity data of the auxiliary roller 1 .

[0069] The processor 3 determines whether the cash register printer is jammed according to the angular velocity change rate of the auxiliary roller 1 during printing.

[0070] Specifically, in actual implementation, an angular velocity sensor can also be provided in the auxiliary roller 1, and the angular velocity sensor can collect the angular velocity data of the auxiliary roller 1, so that when the cash register printer prints, along with the rotation of the auxiliary roller 1, the angular velocity sensor It can also rotate accordingly, and because the speed of paper output is basically constant when the cashier printer is printing, the rotation speed of the auxi...

Abstract

The invention provides a cash register printer paper jam detection system and method and a cash register printer, and the system comprises a printing paper cabin, and also comprises an auxiliary roller which is arranged in the printing paper cabin and is used for assisting paper feeding during printing; the rotation detection module is connected with the auxiliary rolling shaft and used for collecting rotation data of the auxiliary rolling shaft when the cash register printer prints; and the processor is connected with the rotation detection module and is used for judging whether the cash register printer is jammed or not according to the rotation data of the auxiliary rolling shaft. According to the scheme, paper jam detection is more timely, paper jam can be found in time at the initial stage, and the cashier printer is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of cash register printers, in particular to a paper jam detection system and method for a cash register printer and a cash register printer. Background technique [0002] A printer is one of the output devices of a computer, which is used to print computer processing results on related media. There are three indicators to measure the quality of a printer: printing resolution, printing speed and noise. There are many types of printers. According to whether the printing element has an impact on the paper, it can be divided into impact printers and non-impact printers; according to the way a line of characters is formed on paper, it can be divided into serial printers and line printers; Advanced technology, sub-cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers. [0003] The cash register printer is a kind of printer, mainly used for paper printing...
