Abstract:
An image exposure apparatus which controls emission of a light beam from a light source based on an image data signal to record an image on a photosensitive material by scanning the light beam, comprising:main scan means which moves the light source with respect to the photosensitive material in a predetermined main scanning direction;sub-scan means which moves relatively the light source and the photosensitive material in a direction perpendicular to the main scanning direction for each main scan effected by said main scan means;a detecting sensor which detects a start position of said main scan means;moving a mount detecting means which detects an amount by which the light source is moved in the main scanning direction; andmain scan exposure control means which controls an exposure start timing of a light beam in each of the second and subsequent main scan operations until the first main scan operation for scan recording starts, with reference to a detected value of an amount of movement detected by said moving amount detecting means when the start position of said main scan means is detected by said detecting sensor.
