Claims

[Scope of utility model registration request]

A holder for attaching a light emitter or a light receiver to a board and having an adjustable function for aligning the optical axes of the light emitter and light receiver, a two-point adjustable screw having a flat surface that overlaps with the board. A first adjustment means that allows the fixed table to swing in a radial direction parallel to the substrate within the range of a horizontally long hole provided on the other side using a hole provided on one side as a rotation fulcrum, and the adjustable fixed table. It has an upright plate integrally extending in the right angle direction and a holder that overlaps the upright plate and holds the emitter or receiver, and is equipped with a pin that locks into a small hole in a pothole provided on the board side of the upright plate. A tightening screw hole is formed in the plate corresponding to the horizontally long hole provided on the opposite side of this pin, and the optical axis of the emitting or receiving device is connected to the board through the holder within the horizontally long hole using the pin as a rotation fulcrum. and a second adjusting means that can be oscillated in a radial direction perpendicular to the light source, and a two-point tightening bolt of the adjustable fixing base is disposed outside the blind spot of the light receiver. Axis adjustment mechanism.
