Description

DETAILED DESCRIPTION OF THE INVENTION [Ill Utilization Count] The present invention relates to a sheet-like photographic paper processing apparatus that distributes sheet-like photographic paper into a plurality of rows and conveys them.

[Prior Art] In a conventional photographic paper processing device that exposes an image to a strip of photographic paper and develops the exposed strip of photographic paper, frame positions are indicated at the boundaries of printing exposure order units of the strip of photographic paper. After making punch holes or exposing several types of marks, the strip-shaped photographic paper is cut by detecting the punch holes or marks after the development process.

In addition, in order to perform exposure and development processing quickly, a photographic paper processing method involves exposing an image to a sheet of photographic paper cut from a strip of photographic paper, and then distributing the exposed sheet of photographic paper into multiple rows and conveying them in parallel. In the equipment, the order unit for printing and exposure was determined by comparing the number of sheets ordered with data on the number of sheets of exposed photographic paper.

[Problem I that the invention seeks to solve] As mentioned above, in order to speed up the exposure and development process, it is desirable to convey exposed sheets of photographic paper in parallel, but since each image frame is separated, , punch holes or marks cannot be added to the boundaries of order units.

In addition, in the case of a management method based on the number of sheets ordered, if only one sheet of photographic paper that has been exposed and developed is jammed and is not ejected from the automatic processor, an error will occur in the classification of the order unit. Become. Also, with this management method, in order to check the number of sheets ordered and the number of exposed sheets of photographic paper,
Only after all the sheets of photographic paper being processed have been ejected.
It is not possible to determine whether there is a jam or not.

On the other hand, in an automatic developing machine that uses this parallel conveyance method for sheet-shaped photographic paper, the number of exposed photographic papers that are conveyed is larger than in the above-mentioned method that exposes and develops strips of photographic paper.
Detailed conveyance management is not possible unless jam detection is performed in as fine a manner as possible. One method for this detailed jam detection is to detect multiple sheets of photographic paper being conveyed at each processing step in an automatic processor. One possible method is to install a sensor to check whether there is a jam. However, this method requires waterproofing of the sensors installed at each processing step.
The cost increases because measures such as rust prevention are required.

In order to solve the above-mentioned drawbacks, the present invention provides a sheet-shaped photographic paper processing apparatus that is capable of reliably determining the printing exposure ordering unit by changing the conveyance pattern of the sheet-shaped photographic paper at the boundary between the printing exposure ordering units. is intended to provide.

In addition, jam detection can be performed quickly with inexpensive equipment.
