Printing device and electronic equipment

Abstract

The invention provides a printing device and electronic equipment. The printing device comprises a support, a sensing structure, a stop structure and a controller. The sensing structure is arranged on the support and used for detecting the specification of a paper roll. The stop structure is transversely and adjustably mounted on the support. The controller is electrically connected with the sensing structure and the stop structure and used for controlling the stop structure to move in the transverse direction according to the detection result of the sensing structure.

Description

technical field [0001] Embodiments of the present invention relate to electronic product technology, and in particular to a printing device and electronic equipment. Background technique [0002] With the development of science and technology, the popularization of mobile payment, etc., smart terminal products such as POS machines are widely used, and the requirements for printers are also getting higher and higher. [0003] In the prior art, paper roll slide rails and front shells are used to adapt paper rolls of different specifications. When paper rolls of different specifications are put in, first move the paper roll slide rails to the corresponding indicated position by hand, and then put the paper rolls into the , the limit of the paper roll slide rail is limited by the cooperation of the bottom rib of the paper roll slide rail and the limit groove of the front shell, which is inconvenient to operate. Contents of the invention [0004] The purpose of the embodiments...
