ABSTRACT:
In a position sensitive photoelectric sensor that calculates a distance to a target based on a triangular range finding using a light and outputs a result compared with a reference distance, first the reference distance Dref is set roughly by using a light receiving portion adjusting mechanism that changes an angle of a light receiving portion including a reception lens and a light receiving device. Then, the change adjustment of the reference distance is performed by teaching. In addition, the user performs a fine adjustment of the reference distance by a manual adjustment using an increase/decrease key if necessary.
