Abstract
A laser light source has a plurality of semiconductor lasers arranged in a direction intersecting a primary scanning direction X. The semiconductor lasers are arranged in such a positional relationship that each semiconductor laser is located upstream, in the primary scanning direction X, of a different semiconductor laser located adjacent thereto and downstream thereof in a direction in which air is blown from an air blowoff pipe.
Claims4
An image recording apparatus comprising:
- a holder member for holding an image recording medium mounted on a surface thereof;
- an image recording device for emitting light beams modulated by image signals toward said image recording medium;
- a primary scanning device for causing said light beams to scan said image recording medium in a primary scanning direction by moving said light beams relative to said holder member;
- a secondary scanning device for moving said image recording device in a direction perpendicular to said primary scanning direction;
- and
- a gas blowing device for blowing out a first gas in a direction intersecting and inclined to said primary scanning direction on a surface along the image recording medium to blow away a second gas generated from said image recording medium irradiated with said light beams;
- wherein said image recording device has a plurality of light sources arranged in a direction intersecting and inclined to said primary scanning direction;
- said light sources being arranged in such a positional relationship that each light source is located upstream, in said primary scanning direction, of a different light source located adjacent thereto and downstream thereof in said gas blowing direction.
