Problems solved by technology

However, the current situation is that photo processing devices using scanning exposure methods cannot change the intensity of the laser light output stably from the laser light emitting device, and can only respond to printing paper with specific color formation characteristics.
For this reason, when using a printing paper having a coloring characteristic different from the specific coloring, the quality of the image formed on the printing paper will be greatly deteriorated

Embodiment Construction

[0017] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

[0018] FIG. 1 is a diagram showing a schematic configuration of a photograph processing apparatus of this embodiment. The photo processing device 10 shown in FIG. 1 is a photo processing device using a digital scanning exposure method by laser, and includes a scanning unit 20 , a printing unit 30 , a processing unit 40 and a finishing processing unit 50 . The long-size printing paper 11 contained in the paper cassettes 31 and 32 described later is conveyed to a cutter 34 described later along a path 18 indicated by a dot-and-dash line in FIG. 1 . Then, the printing paper 11 is cut to a predetermined length by the cutter 34 in the width direction, and is transported from the printing unit 30 to the finishing unit 50 along the path 18 through the processing unit 40 .

[0019] The scanning unit 20 mainly performs various processes such as reading processi...

Abstract

A photographic processing apparatus according to the present invention exposes photographic papers using a laser beam modulated based on image data and includes laser beam emitting device and changeover means for changing over the intensity of the laser beam outputted from the laser beam emitting device in a plurality of levels (for example, three levels consisting of a high level, a middle level and a low level).

Description

technical field [0001] The present invention relates to a photo processing apparatus for exposing printing paper by modulating laser light according to image data. Background technique [0002] In recent years, photograph processing apparatuses employing a so-called digital exposure method have been widely used. Regarding the digital exposure method, the printing paper is exposed by modulating light according to the digital image data. By adopting the digital exposure method, various image processing such as color correction, density correction, and sharpening processing can be performed with a high degree of freedom, and rapid printing and development processing can be performed, thereby achieving reproducibility and analysis in color and density. Good quality prints with good compatibility. [0003] As one of the above-mentioned digital exposure methods, a scanning exposure method in which a printing paper is exposed by scanning modulated laser light using a polygon mirr...
