Image forming device

Abstract

A photographic paper storage part 50 used for accommodating photographic paper P temporarily is arranged on the downstream side of an exposure device used for scanning and exposing on photographic paper P. Said photographic paper storage part 50 consists of a plurality of tubular elements 51, connection elements 52 used for connecting said tubular elements, an electromotor used for rotating said connection elements 52, and the like. Exposed photographic paper P is received temporarily in cylinder shape in said tubular elements 51 and transferred to a feeding unit 12 in the downstream side. Then a buffer part necessary for the exposed photographic paper P is ensured without maximization of the whole equipment. Furthermore, the processing speed is capable of being improved because the exposal process of the next photographic paper is capable of being performed alone whether the tubular elements 51 storing photographic paper is transferred to the next process by storing a plurality of exposed photographic paper at one time through a plurality of tubular elements 51.

Description

technical field [0001] The present invention relates to an image forming apparatus, and more particularly to an image forming apparatus including an image forming unit that forms an image on an image forming surface while conveying an image forming medium by a conveyance mechanism. Background technique [0002] As the image forming apparatus used for film development is known, there is an apparatus that performs image exposure on photographic paper (for example, photosensitive paper or the like, which corresponds to an imaging medium) using laser light. Figure 12 shows an example of such a device. The device is set to read the frame image data formed on the developed film or the image data stored in various storage media, and perform image developing and exposure on the latex side of the photographic paper according to the image data. [0003] As shown in FIG. 12 , the photo paper cassette 100 accommodates a cylindrically wound photo paper. The photo paper extracted from t...

Problems solved by technology

However, when printing on photo paper with a long print size, it is necessary to provide a pre-exposure buffer or a post-exposure buffer corresponding to the print size, so that the transport path becomes longer or the storage space 107 becomes larger accordingly. This leads to an increase in the overall size of the image forming apparatus

[0007] In this regard, for example, it is conceivable to wind a long strip of photographic paper into a cylindrical shape and store it temporarily, but in the structure of winding and storing the above-mentioned photographic paper, it cannot be processed until the stored photographic paper enters the next process. The processing of the next photo paper, so the processing of the photo paper will stagnate in the storage section, thereby reducing the overall processing capacity of the device
