Abstract

PURPOSE:To perform exposure and development by one set, and to reduce occupation area and eliminate the need to align and superpose negative paper and positive paper one over another, by mounting a developing device equipped with a dual-system transfer system, a developing tank, a squeezing roller, and a diffusion transfer chamber. CONSTITUTION:The limit switch 59 of a negative material transfer system 40 is normally off, and a clutch is connected in the ON state wherein an actuator 59a is pressed to drive a couple of roller shafts on the upstream side of the limit switch 73 of a positive material transfer system 60. Positive material inserted into the transfer system 60 precedently stops once the actuator 73a of the limit switch 73 is pressed and then enters a stand-by state. Then, the exposed negative material is inserted into the transfer system 40, and when the actuator 59a of the limit switch 59 is pressed, the tranfer of the positive material is restarted synchronously to insert those negative material and positive material into the developing tank 80 while aligning the slightly precedent negative material to the positive material.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an autoprocessor capable of performing exposure, paper printing, or halftone dot separation, which can be enlarged and reduced.

In the field of photoengraving, conventional methods have been to use an exposure device to enlarge or reduce the image of a material such as a manuscript, or to expose a negative material with the same dimensions and perform halftone dot separation, or to perform halftone dot separation on the exposed negative material. The two papers were stacked one on top of the other and placed in a developing device, and after passing through a developing tank, the two papers were brought into close contact with a squeezing roller and paper printing was performed by a diffusion transfer (DTR) reaction.

In other words, in the case of paper printing or halftone dot separation by photolithography, conventionally, two separate exposure devices and two developing devices are required, which requires a large area and has poor work efficiency. Furthermore, when printing paper, it is necessary to manually align and overlap the exposed negative waves with the exposed negative waves and then put them into the developing device. Both waves in the adhered state were removed for the entire time required for complete diffusion transfer, and the film was peeled off after the required time had elapsed.

The present invention has been made in view of the above-mentioned circumstances.The purpose of the present invention is to enable exposure and development to be carried out in one unit, to occupy a small area of the apparatus, and to combine negative and positive images during paper printing. An object of the present invention is to provide an autoprosensor which eliminates the manual work of aligning and superimposing the heads of the target and the target, and furthermore allows the time required for the diffusion transfer reaction to be maintained within the apparatus.
