OPTICAL HEAD DEVICE OF A SELF-PROPELLED TYPE
First Claim
1. An optical head device for recording an image, in which an optical head for emitting a printing light is moved in a first direction being parallel with a surface of a photosensitive recording medium, comprising:
- a head module having said optical head built therein;
a reduction mechanism provided in said head module, said reduction mechanism including a pair of drive gears;
a chassis for movably supporting said head module;
a pair of rack gears formed on said chassis, the pair of said rack gears respectively meshing with the pair of said drive gears of said reduction mechanism; and
a motor provided in said head module and connected to said reduction mechanism, said motor moving said optical head in said first direction together with said head module by rotating said drive gear on said rack gear.

Abstract
A head module contains a head motor, a reduction mechanism, and an optical head. The optical head is disposed behind an opening through which printing light is emitted toward an instant film. Both sides of the head module are provided with pinion gears rotated by the head motor via the reduction mechanism. A chassis is provided with rack gears respectively meshing with the pinion gears. The head module is reciprocated in a sub-scanning direction by the head motor. During the reciprocation of the head module, the printing light is emitted from the opening in accordance with image data to expose the instant film. A driving mechanism for the head module does not exist outside a movement range of the head module so that it is possible to downsize an instant printer using this head module.
