In this surface light source device, light is incident from a plurality of point light sources arranged on a one side end surface of a light guide plate is reflected on a light reflecting surface on a rear surface of the light guide plate and is emitted from a front surface of the light guide plate The point light sources comprise white light emitting diode elements. Two white light emitting diode elements out of six of the white light emitting diode elements having chromaticity outermost from a center of an aimed chromaticity range in opposite hue directions are arranged in an approximately center of a group of the white diode elements.

Surface light source device and adjusting method of chromaticity thereof

A UV-fixable thermal recording apparatus uses UV-fixable color thermal recording paper, uniformity of light intensity distribution, high efficiency and miniaturization of a fixing lamp to prevent degradation of the print quality this apparatus has at least one fixing lamp, and a row of heating resistors in the form of a plurality of heating resistors arranged parallel to the direction of paper delivery. The width in the direction of paper delivery of an area of the paper exposed by the fixing lamp is made larger than the length of the row of heating. resistors. The fixing lamp and the row of heating resistors are so arranged that the position of an (end on the upstream side in the forward direction of paper delivery) of the exposed area of the fixing lamp is on the downstream side of the position of an end (on the upstream side in this direction) of the row of heating resistors.
