Claims

[Scope of utility model registration request]

(1) A mirror holder with a spherical holder that holds the mirror and has a concave spherical surface, an elastic support mechanism that elastically supports the mirror holder with a spherical holder against the main body so that it can move about a point as a fulcrum, and a spherical holder with a tip end. It is composed of a stick that is in contact with the concave spherical surface of the mirror holder, is supported at one point by the main body, and can be rotated around this point. In the laser beam scanning mechanism that converts the movement of the stick into the tilt of the mirror by setting different values, the above elastic support mechanism is a spherical sliding bearing installed between the mirror holder with a spherical bearing and the main body. and a compression coil spring.

(2) The laser beam scanning mechanism according to claim (1), which is a utility model and has a steel ball at the tip of the stick.

(3) The rotation support mechanism of the stick consists of a spherical sliding bearing and a compression coil spring.
) or (2).

(4) The rotation support mechanism of the stick uses a spherical sliding bearing and zero
A laser beam scanning mechanism according to claim 1 or 2 of the utility model registration claim, which comprises a ring.
