Abstract: A label printer with a paper-cutting mechanism includes a force-applying assembly operatively coupled to a paper-cutting assembly. The force-applying assembly receives an applied force and drives the paper-cutting assembly to move. The paper-cutting assembly includes a blade assembly and a paper-pressing assembly operatively coupled together, and an elastic member disposed between the blade assembly and the paper-pressing assembly. The blade assembly is supported by the force-applying assembly, while the paper-pressing assembly moves vertically relative to the blade assembly. The front-back and left-right movements of the paper-pressing assembly are restricted by the blade assembly. The paper-pressing assembly includes a paper-pressing plate and a first positioning pin, with one end of the elastic member connected to the first positioning pin. The blade assembly includes a blade and a blade holder with a second positioning pin. The other end of the elastic member is connected to the second positioning pin.

Abstract: The provided are a chip assembly and an imaging material box. The chip assembly is configured to be installed in the imaging material box. The imaging material box is detachably installed on an imaging device provided with a stylus. The chip assembly includes a chip and a conductor. The chip includes a substrate and a plurality of contact portions arranged on the substrate. The plurality of contact portions include a front contact portion arranged on one side of the substrate and a back contact portion arranged on the other side of the substrate. In this way, the risk of the chip being short-circuited can be effectively reduced.
