Claims

[Scope of utility model registration request]

(1) Each small plane of the mirror that makes up the polygon mirror is
A polygon mirror, characterized in that the mirrors are arranged equally on the maximum circumscribed circle of the polygon mirror without touching each other, but with convex curved surfaces in contact with the maximum circumscribed circle interposed therebetween.

(2) A polygon mirror in which the convex curved surface in contact with the maximum circumscribed circle in claim 1 of the utility model registration claim is a convex spherical surface.

(3) A polygon mirror in which the convex curved surface in contact with the maximum circumscribed circle in claim 1 of the utility model registration is a convex cylindrical surface.
