PURPOSE:To enable the angle adjustment of a motor shaft highly precisely and rapidly by a method wherein screw holes to be provided in the flange part to equip a motor to a pedestal are formed in a circular arc form, the motor is rotated at a necessitated angle with an adjusting knob and is fixed with screws. CONSTITUTION:When a transferring block 16 is to be driven by a stepping motor 11 using a pulley 13 and a belt 15, a cylindrical faucet part 11a is formed making a rotating shaft 11c as center in a flange 11b for the equipment of the motor 11 to a pedestal 10, and penetrated screw holes 111-114 are formed respectively in a circular arc form at the circumference of the faucet part 11a. A long hole A confronting with a small hole B in the pedestal 10 is provided in the flange, and a rotatable adjusting knob 17 having a small diametrical tip part 171 and a large diametrical eccentrical part 172 is inserted in the holes. By rotating the adjusting knob, the motor 11 is rotated at a necessitated angle, and the flange 11 is fixed to the pedestal 10 with screws 12. |
