Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a photographic paper printing apparatus that conveys a sheet of photographic paper obtained by cutting a strip of photographic paper to an image printing section and exposes it to light.

[Prior Art] Some photographic paper printing devices cut, for example, a strip of photographic paper into sheets of photographic paper, convey this sheet of photographic paper to an image printing section, and perform exposure processing in this image printing section. .

With this conventional photographic paper printing device, it was necessary to change the feeding direction of the negative film and the size of the strip of photographic paper to be cut, depending on the size of the negative film carried into the image printing section and the size of the sheet of photographic paper to be exposed. .

For example, the size of the negative film carried into the image printing department is 1.
35 full size to 135 half size, but if the size of the sheet of photographic paper to be exposed remained unchanged, it became necessary to rotate the feeding direction of the negative film by 90 degrees.

Also, even if the size of the negative film is the same, if the size of the sheet of photographic paper changes, for example from E size to 2E size, or L
When changing from size to 2L size, etc., do you change the feeding direction of the negative film and use the same strip of photographic paper, or do you change the size of the strip of photographic paper without changing the feeding direction of the negative film? , I had to use one of the methods.

[Problem to be Solved by the Invention] As mentioned above, in the conventional photographic paper printing apparatus, when there is a change in the size of the negative film or the size of the sheet-like photographic paper, the feed direction of the negative film must be changed. It was also necessary to change the size of the strip of photographic paper to be cut.

However, when it comes to transporting negative film both vertically and horizontally, the operator has to perform two types of negative transport operations, and the negative carrier that transports the negative film must be rotated 90 degrees, making the operation more complicated than transporting negative film in one direction. There was a drawback that it became. Furthermore, since it is necessary to take measures to prevent the occurrence of scratches on the negative film in both the vertical and horizontal transport directions, there is a drawback that the apparatus becomes expensive.

On the other hand, if you want to change the size of the strip of photographic paper midway through,
It is necessary to once rewind the photographic paper strip being conveyed, then replace the magazine that stores the photographic paper strip, and then transport the replaced photographic paper strip into the photographic paper printing apparatus again. For this reason, strips of photographic paper tend to be lost when replacing them, and strips of photographic paper must be prepared for each size of sheet-like photographic paper.
There was a flaw that made management complicated.

In addition, if negative film is to be conveyed both vertically and horizontally, the peripheral equipment connected to the photographic paper printing machine, such as a negative developing machine, scanner, cutter inserter, etc., must be transported in both vertical and horizontal directions as the negative film is automatically fed. Therefore, there was a drawback that the cost was high.

The purpose of this invention is to eliminate the above-mentioned drawbacks of conventional photographic paper printing devices.By rotating the sheet-shaped photographic paper by 90 degrees with respect to the direction in which it is fed, there is no need to rotate the negative film, and the operation is easy. The object of the present invention is to provide an inexpensive photographic paper printing device that can perform positioning with high precision.

Another object of the present invention is to provide a photographic paper printing apparatus which reduces the work of replacing the strip of photographic paper by rotating the sheet of photographic paper and eliminates the above-mentioned drawbacks associated with replacing the strip of photographic paper.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the photographic paper printing apparatus of the present invention conveys a sheet of photographic paper obtained by cutting a strip of photographic paper to an image printing section, and prints an image in the image printing section. In a photographic paper printing device that exposes a photographic paper to light, when the sheet-like photographic paper is carried into the image printing section, the sheet-like photographic paper is rotated by 90 degrees within the plane of the sheet-like photographic paper with respect to the direction in which the sheet-like photographic paper is conveyed. It is characterized by having a photographic paper direction changing section that can change the direction of the photographic paper.

[Function] The photographic paper printing apparatus of the present invention transports the sheet-like photographic paper obtained by cutting the strip-like photographic paper and transports the sheet-like photographic paper into the image printing section. The photographic paper is rotated by a direction converting section capable of rotating 90 degrees within the plane of the paper, or is transported to the image printing section without being rotated.
