Abstract: A red image light signal emitting array, a green image light signal emitting array and a blue image light signal emitting array are driven by separate drivers in accordance with one-line image data at a time. The light signals emitted from the arrays are processed by a light signal combining lens and then are incident to a scanning mirror. The scanning mirror vibrates within a specified range of scan angles at a specified frequency, and while the scanning mirror reciprocates once, one frame of two-dimensional image is formed on a projection surface. The scan angle of the scanning mirror is detected by a detector, and the detector sends a detection signal to a timing signal generating circuit. The timing signal generating circuit is stored with values specified for the respective drivers, and when the detector detects that the scan angle becomes one of the values, the timing signal generating circuit sends a timing signal to the corresponding driver.

Abstract: An image reading apparatus is provided with a photoelectric conversion element to be irradiated with the projected light of an original image photographed on a film and is adapted to read out the image. The component lines of the image information in the direction of main scanning are halved by a half mirror and the corresponding halved portions of the image information are simultaneously read out by a first line sensor and a second line sensor. These line sensors are disposed in mutually equivalent positions relative to the half mirror. The direction of motion of the film perpendicular to the direction of main scanning relative to the line sensors is selected between a first direction of motion and a second direction of motion opposite to the first direction of motion. From these line sensors, the image information is produced in the order in which the image information was read out, no matter whichever of the two directions may be selected.
