傷付ける恐れのあるものであつた。 Pulse motors are often used to transport the carriages of serial printers, X-Y plotters, etc., and to rotate the type wheels of printers, and the pulse motor and the driven body are connected via gear trains, wires, etc. . Then, a gear is attached to the drive shaft of the pulse motor so that the pulse motor is in a specific phase (specific rotation stop position) at the transfer reference position of the driving body, and the reference position of the driven body and the specific phase of the pulse motor are The pulse motor is driven and controlled based on this specific phase. However, in the conventional method of attaching and adjusting the position of gears to this type of pulse motor, the drive shaft of the pulse motor, which has stopped rotating at a particular phase, is held rotatably with a chuck, etc., and the drive shaft attached to this drive shaft is gears,
Rotate the driven body (such as the carriage) so that it comes to the reference position while meshing with the driven gear,
However, since the rear drive gear was fixed to the drive shaft with a set screw, the installation and position adjustment work was relatively troublesome, and the teeth of the drive gear were held between jigs for rotational positioning, so the jig was difficult. The tool was slippery and could damage the teeth.
