Embodiment 1

[0033] refer to Figure 1 to Figure 4 As shown, the carbon ribbon cassette 100 includes a supply reel 20 , a take-up reel 30 and a casing 10 , the carbon ribbon is wound on the supply reel 20 , and the take-up reel 30 takes up the carbon ribbon output from the supply reel 20 . The supply reel 20 and the take-up shaft 30 are rotatably disposed in the housing 10 , and are substantially parallel to each other. Rotation limiting portions are respectively provided on the supply reel 20 and the take-up reel 30 . Preferably, the rotation limiting part is located at the end of the supply reel 20 or the take-up reel 30 .

[0034] The housing 10 includes an upper case 11 , a first lower case 12 and a second lower case 13 . The first lower casing 12 defines a first storage space 121 for the reel 20 , and a first bearing portion 122 is disposed in the first storage space 121 , and the first bearing portion 122 rotatably supports the reel 20 . Both ends of the first lower case 12 are re...

Embodiment 2

[0044] The printing device (not shown in the figure) includes a main body of the printer and a ribbon cassette 100 , and the ribbon cassette 100 can be installed or removed from the main body of the printer. The side of the main body of the printer is provided with an insertion opening through which the ribbon cassette 100 can be inserted and installed on the main body of the printer. The ribbon cassette 100 is designed to be detachable relative to the main body of the printer, which is convenient for maintenance and replacement of the ribbon cassette 100 . In the embodiment, the carbon ribbon cassette 100 is installed or disassembled along the direction of the rotation axis of the supply reel 20 or the take-up shaft 30 , and the insertion opening is reduced so that a structure capable of stably supporting the carbon ribbon cassette 100 is designed in the housing 10 .

[0045] The main body of the printer is provided with a contact surface in contact with the contact portion 4...

Abstract

The invention provides a carbon belt box. The carbon belt box comprises a scroll supplying shaft, the carbon belt winds around the scroll supplying shaft; a scroll receiving shaft, the scroll receiving shaft is used for receiving the carbon belt outputted by the scroll supplying shaft, rotation limiting parts are respectively arranged on the scroll supplying shaft and the scroll receiving shaft; an outer housing, the scroll supplying shaft and the scroll receiving shaft are rotatably arranged in the outer housing; an elastic joint component, the elastic joint component is jointed with or separated from the rotation limiting part of the scroll supplying shaft and the rotation limiting part of the scroll receiving shaft; the elastic joint component can be elastically deformed in the axis direction of the scroll supplying shaft and in the axis direction of the scroll receiving shaft; the elastic joint component comprises a contact part, the contact part is matched with a printer main body; the contact part bends in the direction of the jointing with the rotation limiting parts. The contact part of the elastic joint component bends in the direction of the jointing limiting with the scroll supplying shaft or the scroll receiving shaft, the problem that the elastic joint component deforms in the direction of breaking away from rotation limiting under pressure can be solved.

Description

technical field [0001] The present invention relates to the technical field of printers, in particular to a carbon ribbon box and its printing equipment. Background technique [0002] At present, in order to facilitate the replacement of the ribbon cassette when the ribbon is exhausted or printing errors occur, the ribbon cassette and the main body of the printer are usually detachable structures. A cylindrical take-up reel and supply reel are accommodated in the carbon ribbon cassette, and the thermal head is pressed against the roller to form a printed image when the carbon ribbon overlaps with the recording paper. [0003] Before the ribbon cassette is installed on the main body of the printer for use, the ribbon cassette is in the process of being transported, causing external vibrations to exert force on the ribbon cassette. The force applied to the ribbon cassette may cause the ribbon wound on the supply spool or take-up spool to loosen and be pulled out of the ribbon...
