Embodiment 1

[0031] refer to Figure 1 to Figure 9 As shown, the printing device 100 includes a base 1, a driving device 2 and a printing unit 3. The base 1 is used to carry the driving device 2 and the printing unit 3, etc., and the driving device 2 transmits driving force to the printing unit 3, so that the printing unit 3 Complete the corresponding functional actions. Of course, the driving device 2 can also transmit driving force to other structures or devices. The base 1 includes the shell of the printing device 100 and the support provided in the cavity of the shell, etc., for containing, covering, bearing, and fixing other structures or devices of the printing device 100. Of course, the above structures or devices can also be fixed, Detachable, movable connection and other modes are arranged on the bracket. The printing unit 3 can leave marks on the recording medium X passing therethrough, and the recording medium X refers to a substance on which printing marks can be left by the ...

Embodiment 2

[0045] The printing system, using the printing apparatus 100 in Embodiment 1, further includes a supply cassette 200 . The supply box 200 is detachably connected to the printing device 100 , and the supply box 200 includes a tray 204 on which several recording media X are stacked. The recording medium X is output from the supply box 200 and delivered to the printing unit 3 for printing.

[0046] The supply box 200 includes a carrier 201, a tray 204, a first cover 202 and a second cover 203, the carrier 201 has a cavity for placing the recording medium X, the first cover 202 and the second cover 203 The trays 204 are disposed on the carrier body 201 so as to be openable and closable, respectively. The carrier 201 refers to a structure capable of carrying, placing and containing the recording medium X, for example, a shell structure including an opening at the bottom.

Abstract

The present invention provides a structure for accurately locating a thermal printing head. The structure includes a thermal printing head assembly and a base, wherein the thermal printing head assembly can leave traces on a recording medium; the thermal printing head assembly includes a first support carrying an elongated thermal printing head, and a second support which is driven by a driving force to rotate around an axis; when rotating, the second bracket drives the first bracket to rotate synchronously; the first bracket is stressed so as to move; the first bracket is provided with a first limiting portion; the base is provided with a second limiting portion; and in a printing state, the first limiting portion and the second limiting portion cooperate so as to limit the first bracketto make the first bracket located at a printing reference position. According to the structure of the invention, the first bracket is provided with the first limiting portion, and the base is providedwith the second limiting portion; and in the printing state, the first limiting portion and the second limiting portion cooperate so as to limit the first bracket to make the first bracket located atthe printing reference position; and therefore, the influence on a printing effect caused by too large deviation between a heating position and the tangent line of the thermal printing head assemblyon a paper pressing roller which is further caused by the movement of the thermal printing head assembly under the action of the traction force of the recording medium can be avoided.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a structure for accurately positioning a thermal printing head, a printing device and a printing system. Background technique [0002] Most printers are used in offices or homes. There are many types of printers, including inkjet, thermal, thermal transfer, electrostatic and other printers according to the technology used. Usually, the printing module includes a rubber roller and a thermal print head unit, and the two have a variety of cooperative relationships to adapt to different working conditions. It is often necessary to design the thermal print head unit to be able to be lifted relative to the rubber roller or pressed against the rubber roller . When the thermal print head is pressed against the rubber roller, an elastic member is required to exert a certain elastic force, so the thermal print head has a certain movable space relative to the fixed bracket. However, due ...
