Claims

[Scope of utility model registration request]

At least one pair of positioning rods are erected on a write head that outputs an image signal according to input information toward the surface of a rotatably supported image carrier;
A positioning portion made of a circumferential surface or a spherical surface is formed on at least the distal end portion of the rod, and at least two A tapered recess having a slope formed thereon is provided, and the image carrier is constantly rotated in a state in which the rod is accommodated and rotatably supported by abutting the tip positioning portion of the rod against the slope at the end of the recess. A positioning mechanism for a write head in a recording device, characterized in that the center of curvature of the positioning portion is located on a center line.
