螺旋面になっている。FIG. 2 shows the print head 2, adjustment member 8, and
The details of the holding member 7 and the reference roller 6 are shown. The adjusting member 8 has a hole 8d provided near one end thereof, and a pin above the holding member 7 for holding the reference roller 6 is provided.
The pin 7b is fitted to the pin 7b and is rotatable about the pin 7b in a horizontal plane. In addition, the hole 8d of the adjusting member 8
A gear 8c that meshes with the adjusting worm gear 11 provided on the upper portion of the holding member 7 is cut at the end opposite to
Further, the upper surface 8b of the adjusting member 8 is provided with the adjusting member 8 on the pin 7b.
So that when the holding member 7 is mounted on the print head 2 in a state of being held via the support member, the lower surface 8a of the adjusting member 8 is located above the holding member 7. It is configured so as to be in contact with and supported by the supporting surface 7a. The lower surface 8a of the adjusting member 8 and the upper supporting surface 7a of the holding member 7 are spiral surfaces centering on the pin 7b.
