Abstract

PURPOSE:To reduce the size of reversal exposing means so that said means can be installed in a developing tank by juxtaposing plural pieces of light emitting diodes having different emission wavelengths in the direction intersecting with the conveying direction of a photosensitive material in such a manner that the light emitting diodes respectively having the different emission wavelengths expose the entire transverse range of the photosensitive layer to which the photosensitive materials oppose. CONSTITUTION:The photosensitive material subjected already to a 1st development in a previous stage is delivered by pinching rolls 24, 26 and is immersed into a developing soln. 46. Before the photosensitive material 20 enters the developing soln. 46, the photosensitive material receives several kinds of the light rays of different emission wavelengths from an LED array 48 by which the reversal exposing is executed. The reversal exposing of the photosensitive material 20 takes place in this case when the entire transverse range of the photosensitive layer sensitive in accordance respectively with the light rays of the different emission wavelengths emitted from the light emitting diodes 50-54 is exposed by said light rays. The LED array 48 used as the light source for the reversal exposing is formed by arraying and integrating plural pieces of the light emitting diodes having the different emission wavelengths and, therefore, the array is prepd. into the relatively small size and can be installed in the developing tank 12.
