Description

Technical Field

[0001] The present invention relates to the technical field of printers, and in particular to a consumable material carrying component and a printer. Background Art

[0002] At present, various industries often need to use various types of labels in production and operation, such as labels on shopping malls, transaction receipts, etc. These labels are generally small and are usually printed by printers such as thermal transfer technology. Usually, the printing parameters of such thermal printers are fixed, and parameters such as printing speed and temperature cannot be changed according to different paper rolls. For paper rolls that do not meet the printing parameters, the best printing effect cannot be achieved, and the paper rolls may be damaged, resulting in unnecessary waste.

[0003] Thermal printers in the prior art usually use radio frequency identification technology to obtain relevant information of paper rolls and perform anti-counterfeiting. The technical mechanism is usually to set RFID on the label roll or label paper, and to perform contactless identification through an antenna set on the printer housing. This method has strict requirements on paper roll manufacturing, resulting in high production costs.

[0004] In addition, during the use of the printer, paper jams often occur due to the spread of consumable paper. To address this problem, the printer in the prior art protects the consumables by providing a single independent support shaft and a surrounding structure provided on the support shaft. The support shaft is assembled on the printer to support the consumables and the surrounding structure is used to limit the consumables on the support shaft to prevent the consumable paper from spreading. However, this structure makes it difficult for users to replace consumables. The operation of replacing consumables is relatively complicated, time-consuming and labor-intensive, affecting the user experience. Summary of the invention

[0008] Alternatively, the printer body is provided with a housing portion, the housing portion is configured as a capacitor, and the consumable material carrying member is placed in the housing portion.

[0009] In the above technical solution, the above two methods are convenient for distinguishing different printing consumables, and can reduce manufacturing costs compared to using RFID technology for identification. Specifically, when a conductive part is provided on the consumable bearing member and an electrical contact part is provided on the printer body, after the consumable bearing member contacts or is electrically connected with the electrical contact part to form a conductive loop, the circuit of the printer is connected and the circuit state changes; when the accommodating part of the printer is set as a capacitor, after the consumable bearing member is placed in it, the consumable bearing member is equivalent to the medium of the capacitor, and when different consumable bearing members are placed, the capacity of the capacitor will change.
