Problems solved by technology

In addition, if the paper is squeezed between the fixed knife set 32 ​​and the movable knife set 34, or if there is a hard foreign object between the fixed knife set 32 ​​and the movable knife set 34, the paper cutting mechanism may also have a knife jamming probability.
At present, the previous technology can only eliminate the knife jam through complex mechanism design when the knife jam occurs, but cannot prevent the knife jam from happening.

Abstract

The invention provides a printer, which comprises a housing, a fixed knife group and a mobile knife group. The fixed knife group is arranged in the housing and is in a working position. The fixed knife group comprises a fixed blade and a first support, wherein the fixed blade is arranged on the first support, and the first support has a stop portion. The mobile knife group is arranged in the housing and is arranged oppositely to the fixed knife group. The mobile knife group comprises a mobile blade and a second support, wherein the mobile blade is moveably arranged on the second support, and the mobile blade has a protrusion portion. The vertical distance between the stop portion and the edge of the fixed blade is smaller than the vertical height of the mobile blade. Before the mobile blade makes a contact with the fixed blade, the horizontal distance between the stop portion and the mobile blade is smaller than or equal to the horizontal distance between the fixed blade and the mobile blade.

Description

technical field [0001] The present invention relates to a printer, especially a printer capable of preventing cutter jams. Background technique [0002] Most continuous-feed printers, such as thermal induction printers, provide automatic paper cutting after printing. Most of the paper cutting mechanisms install the movable knife set on the printer housing and the fixed knife set on the openable upper cover, so as to cut paper by cooperation of the movable knife set and the fixed knife set. However, if the fixed knife group deviates from the working position, the paper cutting mechanism may have a knife jamming probability. see figure 1 , figure 1 It is the internal schematic diagram of the printer 3 of the prior art. Such as figure 1 As shown, the printer 3 includes a fixed knife set 32 ​​and a movable knife set 34 . Because the fixed knife group 32 deviates from the working position, therefore, when the movable blade 340 of the movable knife group 34 moves toward the ...
