The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 to 3, the embodiment provides a printer casing, which includes a thermal tape holder 11, a printing holder 21 and a deformation component 3, wherein the thermal tape holder 11 is used to support a thermal tape unwinding assembly and a thermal tape winding-unwinding assembly, the thermal tape unwinding assembly includes a thermal tape unwinding shaft 131 capable of rotating relative to the thermal tape holder 11 to unwind a thermal tape, and the thermal tape winding-unwinding assembly includes a thermal tape winding-unwinding shaft 123 capable of rotating relative to the thermal tape holder 11 to wind a thermal tape. The print carriage 21 is used to support a printhead assembly configured to press the ribbon against a print medium to perform a printing action. The deforming member 3 is disposed between the print holder 21 and the carbon ribbon holder 11. The carbon tape holder 11 is detachably and fixedly mounted on the print holder 21, and the deformation member 3 is configured to be elastically deformed when the carbon tape holder 11 is mounted on the print holder 21. When the printer works, the carbon tape reeling-out or reeling-in speed needs a fixed linear speed v matched with the printing speed, and in the working process, the diameter d of the carbon tape changes in real time, so that the angular speed n ═ v/pi d in the running process of the carbon tape also needs to change in real time, therefore, the driving frequency of the motor 51 for driving the carbon tape reeling-out or reeling-in is also adjusted in real time, when the driving frequency is close to the resonance frequency of the motor 51, a vibration trend can be output from the end of the motor 51, the vibration trend can be transmitted to the connecting part 53 through the transmission system, and then is transmitted to the carbon tape support 11 through the connecting part 53. In order to ensure that the thermal transfer ribbon support 11 can be smoothly mounted on the printing support 21, a certain gap exists between the thermal transfer ribbon support 11 and the printing support 21. The tendency of the vibrations transmitted from the connecting member 53 to the carbon tape holder 11 causes the carbon tape holder 11 to vibrate with respect to the printing holder 21. In order to alleviate the problem, a deformation component 3 is arranged between the printing support 21 and the carbon ribbon support 11, and the deformation component 3 can absorb the relative vibration energy between the printing support 21 and the carbon ribbon support 11, so that the problem that the printing effect of the printer is influenced by the vibration of the carbon ribbon cartridge, and even the printer cannot be normally used can be avoided.

The motor 51 transmits power to the connecting part 53 through the transmission assembly 52 to drive the carbon tape take-up shaft 123 to rotate so as to take up the carbon tape. In other embodiments, the tape winding/unwinding shaft 123 and the tape winding/unwinding shaft 131 are driven by different motors 51 to wind and unwind the tape.
For the driving speed of the motor 51, the motor 51 drives at least one of the tape unwinding assembly and the tape winding assembly to rotate in a manner varying between the first driving speed and the second driving speed; the second driving speed is greater than the first driving speed, and the resonant speed of the motor 51 is between the first driving speed and the second driving speed. In this embodiment, since the resonant speed of the motor 51 is between the first driving speed and the second driving speed, when the motor 51 is at or near the resonant speed, the motor 51 may generate a violent vibration and transmit the vibration to the carbon ribbon holder 11 through the carbon ribbon take-up shaft 123 and/or the carbon ribbon pay-off shaft 131, so that the carbon ribbon holder 11 may vibrate therewith. And then the carbon ribbon between the carbon ribbon reeling and unreeling assembly and the carbon ribbon reeling and unreeling assembly is driven to asynchronously vibrate relative to the printing head. Thus affecting the print quality of the printer. In other embodiments, the driving source 5 may be disposed on the ribbon holder 11.
