DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a print head positioning device in a printer. [Prior Art] This type of printer has a print head disposed on the substrate side of the main body, a platen roller on the swing force bar side, and the swing force bar swings in a direction to close the top of the print head. The platen roller is pressed against the print head, and the recording paper is fed between the print head and the platen roller, and the print head generates heat according to the recorded image to perform recording. [Problems to be Solved by the Invention] The print head and the platen roller are aligned with high precision during assembly. Therefore, high precision is required during assembly to position the print head and platen roller, making assembly work difficult. If the rocking force bar is rocked in the opening/closing direction for a long time, the positional relationship between the platen roller and the printing roller is shifted, resulting in an error, which causes uneven printing. The present invention aims to eliminate the above-mentioned defects.

When setting the cassette 60 on the board 2, with the cover 6 raised, insert the guide frame 68 of the cassette 60 along the cassette insertion guide to a predetermined far end position, and then are fitted into the positioning holes 76 and 78. In this state, the ink ribbon 64 is located on the top surface of the thermal print head 48. When the cover 6 is lowered around the rotating shaft 4, the position adjustment guides 20, 2
The second fitting recess fits into the engagement means 54 on the print head 48 side, and by this fitting, the position of the print head 48 with respect to the platen roller 16 is forcibly adjusted. This position adjustment is performed by sliding the print head rotation shaft 44 along the elongated hole 38 by the regulating force of the position adjustment guide 20.22. The cover 6 is further lowered and locked at a predetermined lowered position.At this time, the platen roller 16 comes into pressure contact with the print head 48 from above the ink ribbon 64, and the print head 48 is moved by the spring 46 due to the pressure from the platen roller 16. The print portion 48a is lowered due to compressive deformation, and the entire area of the print portion 48a is brought into close contact with the surface of the platen roller 16 in parallel with the surface of the platen roller 16 under a predetermined pressure due to the tilting movement about the seesaw shaft 50.
