Abstract
An optical printer device which includes an exposure device which makes relative movements, in a predetermined direction, with respect to a photosensitive body. The optical printer also has a plurality of first, second and third light-emitting elements which emit lights of a first, second and third colors. These light-emitting elements are mounted on a first, second and third mounting substrates, independent of one another, which correspond to the first, second and third colors.
Claims18
An optical printer device comprising an exposure device which makes relative movements, in a predetermined direction, with respect to a photosensitive body, wherein said exposure device has:
- a frame;
- a first mounting substrate for mounting a plurality of first light-emitting elements which emit light of a first color, a second mounting substrate for mounting a plurality of second light-emitting elements which emit light of a second color, and a third mounting substrate for mounting a plurality of third light-emitting elements which emit light of a third color;
- and
- an optical shutter which controls the passage of the light from the first, second and third light-emitting elements to change the amount of irradiation onto the photosensitive body;
- and wherein
- the first, second and third mounting substrates are configured independent of one another, respectively, and are attached to said frame in a manner such that the mounting position of each of the mounting substrates to the frame can be changed independently so that the light emitted from the first, second and third light-emitting elements passes through designated regions of said optical shutter.
An optical printer device comprising an exposure device which makes relative movements, in a predetermined direction, with respect to a photosensitive body, wherein said exposure device has:
- a frame;
- a first light source emitting a first light, a second light source emitting a second light and a third light source emitting a third light;
- and
- an optical shutter which controls the passage of the light emitted from the first, second and third light sources;
- wherein
- said optical shutter has at least three pixel rows, and the first pixel row allows the passage of only a light from the first light source, the second pixel row allows the passage of only a light from the second light source, and the third pixel row allows the passage of only a light from the third light source;
- and
- the first, second and third light sources are attached to the frame in a manner such that mounting positions of the first, second and third light sources are adjustable so that the light emitted from the first, second and third light sources passes through their respective pixel rows.
An optical printer device comprising an exposure device which makes relative movements, in a predetermined direction, with respect to a photosensitive body, wherein said exposure device has:
- a frame;
- light sources, attached to the frame, which emit at least red, green and blue color;
- and
- a liquid-crystal optical shutter which controls the passage of the light emitted from said light sources;
- and wherein
- said light source has a red LED mounting substrate on which a plurality of red LEDs emitting a light of a red color are mounted, a green LED mounting substrate on which a plurality of green LEDs emitting a light of a green color are mounted, and a blue LED mounting substrate on which a plurality of blue LEDs emitting a light of a blue color are mounted;
- said liquid-crystal optical shutter is provided with at least three pixel rows aligned in the direction orthogonal to the direction of said relative movement, and these pixel rows include a red pixel row which controls the passage of light of only red color, a green pixel row which controls the passage of light of only green color and a blue pixel row which controls the passage of light of only blue color;
- and
- said red LED mounting substrate, said green LED mounting substrate and said blue LED mounting substrate are attached to the frame in a manner such that the attaching positions thereof are adjustable so as to be capable of changing the light irradiation angle so that the lights of respective colors are incident to the corresponding pixel rows, respectively.
