備えたものが一般的である。The rotary encoders are roughly classified into an incremental encoder and an absolute encoder. The incremental encoder is used to distinguish between an A-phase signal and a B-phase signal having a phase difference of 90 degrees from each other so that the rotation direction can be determined.
Generally, it is provided with a reference Z signal of one rotation and commutation signals U, V, and W phases for switching the energized phase of the AC servomotor.

のロボット用サーボモータなどに普及している。An absolute encoder is an encoder capable of recognizing an absolute position within one rotation immediately after the power is turned on. The absolute encoder performs a positioning operation between a machine position and a controller immediately after the power is turned on, which is required in a control system using an incremental encoder. Since a certain origin return operation is not required, it is widely used in servomotors for large robots such as articulated robots.

た。However, in the above-mentioned conventional structure, the excess amount of the adhesive applied to the bonding surface of the boss is unevenly spread due to air or the like accumulated between the bosses. In this case, a non-uniform adhesive layer is formed, and the rotational runout of the rotary slit plate becomes large, so that the output signal of the rotary encoder is not correctly output.

The plate mounting surface is provided with one or more grooves and two or more through holes in the grooves, and the rotary slit plate and the boss are fixed to the rotary body of a rotary encoder, and the rotary slit plate mounting of the boss is provided. Since the groove is provided on the surface, the adhesive spreads along the groove, and since the through-hole is provided, the adhesive layer can be made uniform without unevenness of the adhesive due to accumulation of air.
