Abstract
A light irradiating device provided with line light sources is located in association with an image recording medium. The line light sources are located in parallel and at approximately identical pitches with respect to a scanning direction. A slit array plate having slits is located between the image recording medium and the light irradiating device. Each of the slits is located at a position corresponding to the position of one of the line light sources. The light irradiating device is controlled such that line light beams are radiated out one after another with different timing from the line light sources.
Claims32
A read-out scanning exposure method, in which an image recording medium carrying image information recorded thereon is scanned with line light beams having been radiated out from line light sources, the scanning being performed in a scanning direction intersecting with a longitudinal direction of each of the line light sources, in order for the recorded image information to be read out from the image recording medium, the method comprising the steps of:
- i) locating light irradiating means in association with the image recording medium, the light irradiating means being provided with a plurality of the line light sources, each of which radiates out a line light beam toward the image recording medium, the plurality of the line light sources being located at approximately identical pitches with respect to the scanning direction and in parallel with the longitudinal direction of each of the line light sources,
- ii) locating a slit array plate between the image recording medium and the light irradiating means, the slit array plate having a plurality of slits, each of which is located at a position corresponding to the position of one of the line light sources, and
- iii) controlling the light irradiating means such that the line light beams are radiated out one after another with different timing from the line light sources.
A read-out scanning exposure apparatus, in which an image recording medium carrying image information recorded thereon is scanned with line light beams having been radiated out from line light sources, the scanning being performed in a scanning direction intersecting with a longitudinal direction of each of the line light sources, in order for the recorded image information to be read out from the image recording medium, the apparatus comprising:
- i) light irradiating means provided with a plurality of the line light sources, each of which radiates out a line light beam toward the image recording medium, the plurality of the line light sources being located at approximately identical pitches with respect to the scanning direction and in parallel with the longitudinal direction of each of the line light sources,
- ii) a slit array plate, which is located between the image recording medium and the light irradiating means, the slit array plate having a plurality of slits, each of which is located at a position corresponding to the position of one of the line light sources, and
- iii) scanning exposure control means for controlling the light irradiating means such that the line light beams are radiated out one after another with different timing from the line light sources.
