Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a conveyance direction changing unit in a photographic material conveying apparatus that makes it possible to change the conveyance direction of a photographic light-sensitive material.

[Conventional technology]

Conventionally, photographic materials processed in a film processor and subjected to a drying process are taken out of the apparatus by a conveying device, but the conventional conveying device can only be conveyed in one direction. On the other hand, when trying to install a series of processing systems in a store, etc., due to the layout of those systems, if the photographic material is conveyed in only one direction in the film processor, it becomes difficult for the operator to operate the system. There was a problem with that.

[The problem that the idea aims to solve]

The present invention is a conveying direction conversion unit in a photographic material conveying device that can selectively change the conveying direction of a photographic photosensitive material that has undergone a drying process to any direction using a simple mechanism in a film processor. It is intended for the purpose of providing.

[Means to solve the problem]

In order to achieve the above object, the conveyance direction conversion unit in the photographic light-sensitive material conveying apparatus of the present invention constantly cooperates with the main roller for conveying the photographic light-sensitive material in the photographic light-sensitive material conveying apparatus. A guide plate supporting an auxiliary roller support shaft, on which an auxiliary roller is rotatably mounted, parallel to the main shaft on which the main roller is mounted, has a photosensitive shaft on the side of the auxiliary roller. On one side, which is the material delivery side, the side edge facing the auxiliary roller is along the circumferential surface of the auxiliary roller so that it can also be used for guiding the photosensitive material, and is intermediate between the auxiliary roller and the main roller. The end that extends to the first guide piece is opposite to the first guide piece with the auxiliary roller between the first guide piece support shaft to which the sharp first guide piece is fixed. On the side, the side edge facing the main roller has a second guide piece support shaft to which a second guide piece is fixed, which can also be used for guiding the leading edge of the photosensitive material being conveyed. The guide plate is fixed, and the guide plate is centered on the main shaft on which the main roller is mounted, and the auxiliary roller support shaft is arranged in a plane passing through the center of the main shaft parallel to the direction in which the photographic material is carried into the main roller. A stationary position that is on the same side as the loading side of the photographic light-sensitive material and opposite to the main axis with respect to the loading direction, and It is rotatable between the loading side of the photosensitive material and the fixed position on the opposite side, and the length of contact between the photosensitive material being conveyed and the main roller is short, and the photosensitive material hardly bends. The present invention is characterized in that only in this case, the photographic material can be guided by the side edge of the first guide member facing the auxiliary roller.

[Effect]

The conveying direction converting unit in the photographic photosensitive material conveying apparatus of the present invention has the above-described configuration, and the conveying direction converting unit, which is fixed at both ends of a predetermined rotation angle about the main shaft, is used to transfer the conveying direction converting unit to the photographic photosensitive material being conveyed. When the main roller is placed in a fixed position where the length of contact between the material and the main roller is long and causes a large bending tendency on the photosensitive material, and when the main roller is placed in a fixed position where the length of contact is short and causes almost no bending tendency on the photosensitive material. When the photosensitive material is fixed at the fixed position, the direction of conveyance of the photosensitive material is made different by utilizing the bending tendency of the photosensitive material itself.
