Abstract

The invention discloses a printer. A paper feeding channel is formed in a printer main body; the PCB is arranged on the printer main body and is provided with a paper jam detection circuit; the middle part is arranged on the printer main body and is electrically connected with the detection circuit; the trigger component is electrically connected with the detection circuit, and the trigger component further comprises a movable part located in the paper feeding channel; the movable part is configured to be capable of being pushed by paper and making contact with the middle part when the paper is clamped in the paper feeding channel so as to conduct the detection circuit. The CB board is provided with a paper jam detection circuit, when paper jam occurs in the paper feeding channel, the movable part of the trigger component can be pushed by paper and makes contact with the middle component so as to conduct the detection circuit, the PCB main board judges that paper jam occurs after obtaining a paper jam signal and carries out follow-up actions, the structure and the principle are both simple, the concept is novel, the number of elements is small, and cost is low. In addition, the requirement for placement of the spatial position is low.

Description

technical field [0001] The present invention relates to a printer. Background technique [0002] At present, the commonly used printers are mainly led from the printing roll paper to the paper outlet by the printing roll paper winding roller. Still continue to work, unable to stop by itself, waste paper, or even damage the printer. [0003] Or, for example, the Chinese utility model patent application number is 201921966613.5, and the patent name is a patent for a thermal printer with the function of detecting paper jams, which includes a base, a paper cover, and a panel. There is a fixed plate at the bottom, and a paper jam detection plate is installed at the end of the panel close to the paper outlet. They are respectively stuck on the bottom of the fixed plate and the side wall of the paper jam detection plate close to the fixed plate, so that the paper jam detection plate will be pressed to the fixed plate when it is subjected to a torsion force greater than the torsio...
