Abstract
An image recording apparatus includes a recording head connected to a plurality of laser emitters provided in a line; a linear motor displacing the recording head in a secondary scanning direction; and an apparatus controller controlling the emission of laser light from the recording head and displacement of the recording head by the displacer. In response to rotation of a drum, one cycle of scanning by the recording head in a main scanning direction of a plate is completed. For each drum rotation, the apparatus controller displaces the recording head in the secondary scanning direction by displacement amount smaller than the recording width in the secondary scanning direction according to laser light emitted from the plurality of laser emitters.
Claims19
An image recording apparatus performing image recording by irradiating laser light onto a heat-reactive recording medium wrapped around a drum, comprising:
- a recording head coupled to a plurality of laser emitters provided in a line and emitting laser light;
- a displacer displacing the recording head in a secondary scanning direction intersecting with a main scanning direction in which the recording medium is wrapped around the drum;
- and
- a recording controller controlling the emission of laser light from the recording head and displacement of the recording head by the displacer, wherein
- in response to a rotation of the drum, one cycle of scanning by the recording head in the main scanning direction of the recording medium is completed and each time, the recording controller displaces the recording head in the secondary scanning direction with a displacement amount smaller than a recording width in the secondary scanning direction according to laser light emitted from the plurality of laser emitters,
- wherein the plurality of laser emitters are arranged in a plurality of lines inclined with respect to the secondary scanning direction.
An image recording apparatus performing image recording by irradiating laser light onto a heat-reactive recording medium wrapped around a drum, comprising:
- a recording head coupled to a plurality of laser emitters provided in a line and emitting laser light;
- a displacer displacing the recording head in a secondary scanning direction intersecting with a main scanning direction in which the recording medium is wrapped around the drum;
- and
- a recording controller controlling the emission of laser light from the recording head and displacement of the recording head by the displacer,
- wherein in response to a rotation of the drum, one cycle of scanning by the recording head in the main scanning direction of the recording medium is completed and each time, the recording controller displaces the recording head in the secondary scanning direction with a displacement amount smaller than a recording width in the secondary scanning direction according to laser light emitted from the plurality of laser emitters,
- wherein the recording controller performs image recording during one rotation of the drum and the recording controller performs displacement of the recording head in the secondary scanning direction during a next rotation of the drum.
An image recording apparatus performing image recording by irradiating laser light onto a heat-reactive recording medium wrapped around a drum, comprising:
- a recording head coupled to a plurality of laser emitters provided in a line and emitting laser light;
- a displacer displacing the recording head in a secondary scanning direction intersecting with a main scanning direction in which the recording medium is wrapped around the drum;
- and
- a recording controller controlling the emission of laser light from the recording head and displacement of the recording head by the displacer,
- wherein in response to a rotation of the drum, one cycle of scanning by the recording head in the main scanning direction of the recording medium is completed and each time, the recording controller displaces the recording head in the secondary scanning direction with a displacement amount smaller than a recording width in the secondary scanning direction according to laser light emitted from the plurality of laser emitters,
- wherein the drum has a non-recording region defined by a predetermined length in the circumferential direction,
- wherein, when a time during which the non-recording region is located at a recording position of the recording head is greater than a time for displacement of the recording head in the secondary scanning direction, image recording and recording head displacement are performed during each rotation of the drum, and when the time during which the non-recording region is located at the recording position of the recording head is less than the time for displacement of the recording head in the secondary scanning direction, image recording and recording head displacement are performed during alternate rotations of the drum.
