PURPOSE:To reduce the occurrence of the error in the moving direction of a moving body due to deviation in a position between guide shafts and a lead screw, by a method wherein a pin is located at right angles with the guide shafts. CONSTITUTION:Guide shafts 10 and 11 are situated parallel to a lead screw 1. A moving body 9 is linearly guided with the aid of the guide shafts 10 and 11. A pin 4 is supported to the moving body 9, and the pin 4 is engaged with a groove in the lead screw 1. Further, the pin 4 is positioned at right angles with the guide shafts 10 and 11. This constitution enables reduction of the occurrence of the error in the moving direction of the moving body 9. |
