4, and an abutment surface 35 that can abut against the vertical surface 15. The locking body 33 is always urged to move toward the printing head 8 side by the spring force of the coiled spring 29 acting on the arm portion 30.
When the print head 8 is installed, the print head 8 is prevented from coming off upward by the bonding surface 34 and the locking surface 14, and the locking body 33
and the inclined surface 21 of the carriage 3. Also, the second and third
As shown in the figure, a through hole 36 that is narrow at the center and wide at both ends is formed in the vertically intermediate portion of the locking body 33, and the arm portion 30 of the coiled spring 29 is inserted into this through hole 36. As a result, the locking body 33 is swingably supported by the arm portion 30. Through this swinging action, the joint surface 34 and contact surface 35 of the locking body 33 are applied to the locking surface 14 and the vertical surface 15 of the print head 8 attached, regardless of the tilting position of the arm portion 30. It is becoming possible to get closer. Further, the through hole 36 is opened at the lower surface of the locking body 33 so that the arm portion 30 can be inserted therein, and the opening 37 is opened at the bottom surface of the locking body 33.
By being formed obliquely with respect to the longitudinal direction, downward bending of the arm portion 30 when operating the operating portion 31 is restricted.

に組付保持する。 By the way, when the print head 8 is attached to the carriage 3 in the print head support device of this embodiment configured as described above, first the spring force of the coiled spring 29 is applied as shown by the chain line in FIG. The locking body 33 is operated by opposing the operation part 31 toward the outside.
After moving the print head 8 to the lower side of the upper wall plate 25, the engaging surface 13 of the print head 8 is engaged with the inclined surface 21 of the carriage 3, and the print head 8 is placed on the bottom plate 17. At this time, the locking body 33 is moved toward the printing head 8 according to the spring force of the coiled spring 29. Then, as shown by the solid line in the figure, the locking body 33
The joint surface 34 and contact surface 35 of the printing head 8 are joined to the locking surface 14 and the vertical surface 15 of the printing head 8, respectively, and the printing head 8 is pressed toward the left by the spring force of the coiled spring 29 to prevent the engagement. Surface 13 is carriage 3
is brought into close contact with the inclined surface 21 of. Therefore, in this state, the print head 8 is prevented from coming off upward, and the wobbling of the print head 8 can be eliminated. In this case, since the locking body 33 is swingably supported by the arm portion 30 of the coiled spring 29, the locking body 33 relative to the print head 8
can enhance the close effect of Further, the carriage 3, the print head 8, and the locking body 33 are each made of a metal material, and the print head 8
Both sides of the base 12 are connected to the carriage 3 and the locking body 33.
Since the print head 8 is closely held between the print head 8 and the print head 8, the heat generated in the print head 8 during the printing operation is efficiently conducted to the carriage 3 side, and the cooling effect of the print head 8 can also be enhanced. After the print head 8 is attached, the stopper 39 is fitted to the front projection 40 of the carriage 3 to assemble and hold the lead wire 38 on the carriage 3.
