Since it is determined by the amount of movement S 1 of the drive base 1
The amount of movement of head 6 unless the amount of movement S 1 is adjusted.
Adjustment of S2 is difficult, and is impossible unless the operating arm 4 is changed in a device in which the drive base 1 is operated directly by a cam. Also, head 6
The positional accuracy at P 1 and P 2 is determined by the groove of the drive plate 1a, the drive roller 4a held by this, and the driven plate 5.
A highly accurate position cannot be provided due to the fitting gap between the groove and the driven roller 4b held by the groove.
