あった。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, at the transfer reference position of the driving body, a gear is attached to the drive shaft of the pulse motor so that the pulse motor is at a specific phase (a specific rotation stop position), 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, conventionally, the installation and position adjustment of gears on this type of pulse motor is difficult.
The drive shaft of the pulse motor, which has stopped rotating at a specific phase, is held rotatably with a chuck or the like, and the drive gear attached to this drive shaft is held in a state where it is meshed with the driven gear (such as the carriage). Rotate the drive body so that it comes to the reference position,
However, because the rear drive gear was fixed to the drive shaft with a set screw,
In addition to being relatively troublesome to install and adjust the position, the teeth of the drive gear are held between jigs for rotational positioning, which makes the jigs easy to slip and may damage the teeth. .
