Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic processing apparatus in which a positioning member for receiving a roll-shaped photosensitive material in a magazine main body from the outer side in the width direction is provided on the magazine main body so as to rise from the bottom side thereof. The present invention relates to a magazine for storing photosensitive material in a machine.

[0002]

2. Description of the Related Art Conventionally, in a magazine for storing photosensitive material (hereinafter abbreviated as "magazine") in the above-described photographic processing machine, the bottom of the positioning member is fixed to the magazine body by fixing the bottom of the positioning member to the magazine body. It was only attached to the bottom of the body.

[0003]

In this type of magazine, the positioning member is usually formed in a plate shape, and the bottom of the positioning member is formed on the magazine body as in the prior art. In the structure just attached to the bottom,
The positioning action body in the rising state tends to bend in a direction corresponding to the width direction of the photosensitive material due to insufficient rigidity, and it has been difficult to accurately position the photosensitive material in the width direction.

It is conceivable to increase the rigidity by increasing the thickness of the positioning member, but to increase the rigidity of the positioning member with a structure in which the bottom of the positioning member is simply attached to the bottom of the magazine body, positioning is required. The entire thickness of the working body must be considerably thickened, which causes problems such as an increase in the weight and size of the magazine.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to increase the weight of a photosensitive material accommodating magazine in a photographic processor capable of accurately positioning a photosensitive material in its width direction by a positioning mechanism.・ The point is to provide the product without incurring problems such as enlargement.

[0006]

The constitution, operation and effect of the invention according to claim 1 are as follows.

[Structure] In the magazine for accommodating photosensitive material in the photographic processing machine described at the beginning, the bottom of the positioning member is attached to the bottom of the magazine body, and the bottom of the positioning member is aligned with the bottom of the positioning member in the rising direction of the positioning member. The magazine body supports a predetermined positioning action body portion that is separated.

[Operation] The bottom of the positioning member is attached to the bottom of the magazine body, and a predetermined positioning member portion separated from the bottom of the positioning member in the rising direction of the positioning member is supported by the magazine body. For this reason, it is possible to prevent the positioning member from sagging in a direction corresponding to the width direction of the photosensitive material, for example, without making the positioning member thicker than before.

[Effect] Accordingly, a photosensitive material accommodating magazine in a photographic processor capable of accurately positioning a photosensitive material in its width direction by a positioning action body is provided without causing problems such as weight and size increase. We were able to.

The construction, operation and effect of the invention according to claim 2 are as follows.

In the constitution according to the first aspect of the present invention, a photosensitive material guide member for guiding the photosensitive material to the main body of the photographic processing machine through the photosensitive material discharge port is mounted near the photosensitive material discharge port of the magazine body. In this state, the predetermined positioning member is supported by the magazine body via the photosensitive material guide member.

[Operation] In addition to the same operation as the operation according to the first aspect, the following operation can be obtained.

The photosensitive material guide member is one of the components that are accurately positioned with respect to the photosensitive material transport path among a number of components of the magazine. By supporting the predetermined positioning member in the magazine main body, the positioning member can be more easily positioned with respect to the conveying path of the photosensitive material.

[Effect] Accordingly, in addition to the same effect as the effect of the first aspect, the photosensitive material can be more accurately positioned in the width direction by the positioning member. .

The construction, operation and effect of the invention according to claim 3 are as follows.

In the construction according to the second aspect of the present invention, the support connection structure between the photosensitive material guide member and a predetermined positioning action body portion is provided on the engaged portion formed on the photosensitive material guide member with the predetermined position. The engaging portion formed in the positioning action body portion is configured as an engageable coupling structure.

[Operation] In addition to the same operation as the operation according to the second aspect of the present invention, the support connection structure between the photosensitive material guide member and a predetermined positioning action portion is provided by the photosensitive material guide member. Since the engaging portion formed in the predetermined positioning action body portion is configured to be able to engage with the engaged portion formed in the above, it is possible to avoid complication of the support connecting structure, For example, it is possible to easily adjust the position of the positioning member and change the position of the positioning member with respect to the magazine body.

[Effects] Therefore, in addition to the same effects as the effects of the second aspect, the structure can be simplified, the position changing operation of the positioning member can be adjusted, and the positioning member magazine can be used. The work efficiency of attaching and detaching work to the main body could be improved.

The structure, operation and effect of the invention according to claim 4 are as follows.

[Structure] In the structure according to the third aspect of the present invention, with the bottom of the positioning member attached to the bottom of the magazine main body, the positioning member lifts up and rotates around a predetermined axis on the bottom side thereof. The engaged portion and the engaging portion are formed so that the engagement between the engaged portion and the engaging portion can be prevented.

[Operation] In addition to the same operation as the operation according to the third aspect of the present invention, in addition to the above-mentioned operation, with the bottom of the positioning member attached to the bottom of the magazine body,
The positioning action body can be prevented from rising and rotating around a predetermined axis on the bottom side by the engagement between the engaged portion and the engagement portion.

[Effect] Therefore, in addition to the same effect as the effect of the third aspect, the photosensitive material can be more accurately positioned in the width direction by the positioning member. .
