Abstract
An AOD is switched between a state capable of outputting 0th-order light and a state capable of outputting 1st-order light according to a switching signal, and a second delay signal which is produced by delaying the switching signal a given time is generated by a first delay unit and a second delay unit. 0th-order or 1st-order image data is supplied to a laser diode according to the second delay signal to record an image highly accurately on a recording film at a time selected in view of a response delay of the AOD.
Claims16
An exposure recording apparatus for recording a two-dimensional image on an image recording material by applying a light beam emitted from a light source to the image recording material to scan the image recording material relatively in a main scanning direction and in an auxiliary scanning direction, comprising:
- light beam deflecting means disposed in a light path of said light beam, for deflecting said light beam a small distance in a direction different from said main scanning direction, based on a switching signal;
- delay signal generating means for generating a delay signal delayed from said switching signal by a predetermined time, depending on the time required for said light beam deflecting means to deflect said light beam;
- light beam modulating means for modulating said light beam with image information according to said delay signal;
- and
- wherein the light beam is deflected the small distance in the direction different from said main scanning direction to generate a plurality of main scanning lines on the image recording material to record a two-dimensional image thereon by exposure of the image recording material to the light beam.

- a light beam deflector disposed in a light path of said light beam, which deflects said light beam a small distance in a direction different from said main scanning direction, based on a switching signal;
- a delay signal generator which generates a delay signal delayed from said switching signal by a predetermined time, depending on the time required for said light beam deflector to deflect said light beam;
- a light beam modulator which modulates said light beam with image information according to said delay signal;
- and
- wherein the light beam is deflected the small distance in the direction different from said main scanning direction to generate a plurality of main scanning lines on the image recording material to record a two-dimensional image thereon by exposure of the image recording material to the light beam.
