Claims

[Claims for Utility Model Registration] [1] A printing device comprising a platen 12, a carriage 20 that reciprocates along the platen 12, and a printing head 14 mounted on the carriage 20, wherein the printing head 14 is Hold the print head 1
a head holder 16 that is rotatably supported on the carriage 20 so as to allow the head holder 16 to approach and move the head holder 16 toward and away from the platen 12; Part 3
4, the print head 14 is connected to the platen 12.
The lever member 26 is fixed to a rotatably supported drive shaft 28, and is in contact with a driven piece 26a provided on a part of the lever member 26, so that the elastic member 34 Print head 1
4. A pressure contact force adjustment mechanism for a printing head, comprising: a cam means 30 for changing the pressure contact force in stages; [2] The drive shaft 28 includes the cam means 30.
A holder standby cam 32 is coaxially fixed adjacent to the head holder 16, and the holder standby cam 32 removably engages with the engagement protrusion 16a formed on the head holder 16, thereby moving the head holder 16 to the standby position. A press contact force adjustment mechanism for a print head according to claim 1, which is adapted to be able to maintain a print head.
