For example, the guidance set 5 includes the cylinder axis being located on printer pedestal 200 and can moved along the cylinder axis linear
Bearing, the fixed support 4 are fixed on the linear bearing.Guide rail structure and linear bearing structure in embodiment, are real
Stable be oriented to and with optimization can be played in the utility model with what its working experience and professional knowledge were found with new people
Two groups of guidance sets 5 of print quality.
Preferably, the connecting bracket 2 includes main part 22, and is respectively arranged on the first of the both ends of main part 22 and connects
Socket part 23 and second connecting portion 21, and the first connecting portion 23 is located at the main part 22 respectively with the second connecting portion 21
Both sides；First actuator 1 is connected with the first connecting portion 23, second actuator 3 and the second connecting portion
21 connections.By the first output shaft 11, the second output shaft 31 respectively with being connected between being connected, compared to by the cylinder body of actuator and connection
Support 2, the structure of connecting bracket 2 can be simplified so that printer it is compact-sized.Preferably, the first connecting portion 23,
Two connecting portions 21 are mutually perpendicular to the main part 22 respectively.So that the first output shaft 11 and the second output shaft 31 are in vertical direction
It is upper flexible.
Embodiment 2：
Referring to shown in Fig. 1 to Fig. 5, a kind of thermal printer, using the drive device 100 in embodiment 1, printer also wraps
Printer pedestal 200, printhead 6 and rubber roll 300 are included, the drive device 100 is located on the printer pedestal 200, record
Medium 500 is between printhead 6 and rubber roll 300 by the way that the printhead 6 is located in institute's drive device 100, the printhead 6
Carbon ribbon 400 is pressed in the recording medium 500.
The printhead 6 moves to position to be printed by first actuator 1, and passes through second actuator 3
Move to print position, the relatively described moving direction of printhead 6 of the rubber roll 300 is vertical, the printhead 6 in rubber roll 300 just
The square and linear contact lay of rubber roll 300.Printhead 6 contacts with the rubber roll 300 i.e. on the bus of the top of rubber roll 300, avoids
