摘要： The present invention uses LEDs as the light source in a optical printer employing a line scanning method in which an image is produced by relative motion of the light to a photosensitive medium. LEDs are arranged on a mounting substrate with LED pairs, each pair being of the same color, disposed symmetrically as to the center point of the line. Similarly, the power supply lead wires for the LEDs are also disposed symmetrically. In mounting the components on the mounting substrate, a light-intercepting material is used for intercepting light from the side faces of the LEDs.

摘要： The invention provides an exposure apparatus that outputs a stable photographic quality image unaffected by variations in ambient temperature, by suppressing the effects of the temperature variations and achieving accurate grayscale reproduction. In the exposure apparatus, input grayscale data P4 is converted into corrected grayscale data by using a conversion table for correcting for the nonlinearity of exposure density, and grayscale exposure is performed on a photosensitive material by controlling exposure conditions in an exposure head based on the corrected grayscale data; here, the conversion table actually comprises a plurality of conversion tables one for each designated temperature region, and a temperature detector is provided for detecting the ambient temperature, with provisions made to select an appropriate one of the conversion tables under the control of select data in accordance with the temperature data supplied from the temperature detector. The exposure apparatus can thus achieve accurate grayscale reproduction and output a stable photographic quality image even when the ambient temperature varies.
