Description
Technical Field
The invention relates to the technical field of printers, in particular to a printer.
Background
In a transfer printer, it is a common practice to transfer ink on a carbon ribbon to a printing medium to form a pattern.

As shown in fig. 1 to 3, the present embodiment provides a printer, which includes a thermal transfer ribbon unit 1, a printing unit 2, a driving source 5 and a deformation component 3, wherein the thermal transfer ribbon unit 1 includes a thermal transfer ribbon support 11, a thermal transfer ribbon unwinding assembly and a thermal transfer ribbon winding assembly, and the thermal transfer ribbon unwinding assembly and the thermal transfer ribbon winding assembly are respectively and rotatably supported on the thermal transfer ribbon support 11; the printing unit 2 comprises a printing support 21 and a printhead assembly; the printing head assembly is arranged on the printing support 21 and is configured to press the carbon ribbon between the carbon ribbon reeling and unreeling assembly and the carbon ribbon reeling and unreeling assembly against a printing medium so as to record information to be printed on the printing medium; the driving source 5 is arranged on the printing support 21; a deformation member 3 disposed between the print holder 21 and the thermal tape holder 11; the carbon tape support 11 is detachably and fixedly mounted on the printing support 21, and the driving source 5 is configured to engage at least one of the carbon tape unwinding assembly and the carbon tape winding assembly when the carbon tape support 11 is mounted on the printing support 21; the deformation member 3 is configured to be elastically deformed when the thermal tape holder 11 is mounted to the print holder 21, so as to absorb shock transmitted from the driving source 5 to the print holder 21 via the thermal tape holder 11 when the driving source 5 drives at least one of the thermal tape unwinding and winding assemblies to rotate. 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 carbon tape holder 11 can be smoothly mounted on the printing holder 21, a certain gap exists between the carbon tape holder 11 and the printing holder 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, the printer is provided with the deformation part 3 between the printing support 21 and the carbon ribbon support 11, the deformation part 3 can absorb the vibration energy of the carbon ribbon support 11 relative to the printing support 21, and then the problem that the printer cannot be used normally due to the influence of the vibration of the carbon ribbon box on the printing effect of the printer can be greatly reduced.
With respect to the arrangement of the drive source 5, the drive source 5 is disposed on the print carriage 21, and the drive source 5 is configured to engage at least one of the tape pay-off and take-up assemblies when the tape cartridge 11 is mounted to the print carriage 21.

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; wherein 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 further drives the carbon ribbon between the carbon ribbon reeling and unreeling component and the carbon ribbon reeling and unreeling component 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.
