ヤリツジ１１とを固定する。 Here, when fixing the head arm 20 and the carriage 11, it is necessary to perform CE adjustment. C.E.
Adjustment is performed by a CE adjustment device. The CE adjustment device generally includes an arm that tracks the head arm 20, an X, Y table for moving this arm in the X and Y directions, and an output device that outputs a CE waveform in accordance with the movement of the X, Y table. Become. In the CE adjustment work, the arm of the CE adjustment device is made to chuck the chucking portion 24 of the head holding portion 22 (from the direction of the arrow in FIG. 1). At this time, as shown in FIG. 1, the chucking portion 24 is formed with a taper that facilitates chucking in accordance with the structure of the arm of the CE adjustment device. When the head arm 20 is chucked by the CE adjustment device, the head arm 20 is adjusted to the carriage 1.
Perform CE adjustment with the unit set to 1. That is, CE
The positions of the head arm 20 and the carriage 11 are adjusted by slightly moving the head arm 20 while observing the CE waveform output from the adjustment device.
After adjusting the CE, insert the fixing screw 14 into the fixing screw hole 23.
By fitting the head arm 20 into the carriage 11, the head arm 20 and the carriage 11 are fixed.

CE adjustment work can be performed automatically by chucking the arm of the adjustment device.
Furthermore, by fixing the head arm 20 to the carriage 11 with the fixing screw 14 while the arm of the CE adjusting device is chucked after the CE adjustment, it is possible to significantly prevent the position adjustment value from changing when tightening the fixing screw 14. It becomes possible to do so. Further, since the conventional head holding member 12 as shown in FIG. 3 can be omitted, there is also the effect of reducing the number of parts.
