<p>PROBLEM TO BE SOLVED: To miniaturize an instant printer. SOLUTION: A head module 50 accommodates a head motor 55, a deceleration mechanism and an optical head in one body. The optical head is arranged to the depth of an opening 59a. Pinion gears 57 to be driven and rotated by the head motor 55 via the deceleration mechanism are set to both ends of the head module 50. Rack gears 53 to be engaged with the pinion gears 57 are formed to a chassis 48. The head module 50 irradiates a printing light corresponding to image data from the opening 59a while reciprocating in a direction of an arrow B, thereby exposing an instant film 31. Since no driving mechanism for the head module 50 is set outside a move range of the head module 50, the instant printer 25 can be made compact.</p> |
