Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a photosensitive material storage magazine in a photographic processing machine in which a positioning operation body 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. .
[0002]
[Prior art]
Conventionally, in the photosensitive material storage magazine (hereinafter abbreviated as “magazine”) in the above photographic processor, the bottom of the positioning body is attached to the bottom of the magazine body in order to fix the positioning body to the magazine body. It was only there.
[0003]
[Problems to be solved by the invention]
In this type of magazine, the positioning operation body is usually formed in a plate shape, and in the structure in which the bottom portion of the positioning operation body is simply attached to the bottom portion of the magazine body as in the conventional technique, The positioning action body in the standing state is not rigid enough to bend in the direction corresponding to the width direction of the photosensitive material, and it is difficult to accurately position the photosensitive material in the width direction.
[0004]
Although it is conceivable to increase the rigidity of the positioning effector by increasing the thickness of the positioning effector, in order to increase the rigidity of the positioning effector by simply attaching the bottom of the positioning effector to the bottom of the magazine body, The overall wall thickness must be considerably increased, which causes problems such as increasing the weight and size of the magazine.
[0005]
The present invention has been made in view of the above circumstances, and its object is to increase the weight and size of a photosensitive material storage magazine in a photographic processor capable of accurately positioning a photosensitive material in the width direction by a positioning operation body. It is in providing it without inviting such defects.
[0006]
[Means for Solving the Problems]
The structure, operation, and effect of the invention according to claim 1 are as follows.
[0007]
[Configuration] In the photosensitive material storage magazine in the photographic processing machine described at the beginning, the positioning operation body is configured to be adjustable in position in a direction corresponding to the width direction of the photosensitive material, and the bottom of the positioning operation body is A predetermined positioning action portion that is attached to the bottom of the magazine body and is separated from the bottom of the positioning action body in the rising direction of the positioning action body is supported by the magazine body.
[0008]
[Action]
The bottom of the positioning body is attached to the bottom of the magazine body, and a predetermined positioning body portion separated from the bottom of the positioning body in the rising direction of the positioning body is supported by the magazine body. Even if the thickness of the body is not made thicker than before, it is possible to suppress the positioning action body from bending in the direction corresponding to the width direction of the photosensitive material.
[0009]
[effect]
Accordingly, it has been possible to provide a photosensitive material storage magazine in a photographic processor capable of accurately positioning a photosensitive material in the width direction by a positioning member without incurring problems such as an increase in weight and size.
[0010]
The structure, operation, and effect of the invention according to claim 2 are as follows.
[0011]
[Configuration] In the configuration of the invention according to claim 1, the photosensitive material guide member for guiding the photosensitive material to the photographic processing machine main body through the photosensitive material discharge port is attached to the magazine main body near the photosensitive material discharge port. The predetermined positioning action portion is supported by the magazine body via the photosensitive material guide member.
[0012]
[Action]
In addition to the effects similar to the effects of the configuration of the first aspect, the following effects can be achieved.
[0013]
Since the photosensitive material guide member is one of the components that are accurately positioned with respect to the photosensitive material conveyance path among the many components of the magazine, the predetermined material is passed through the photosensitive material guide member. By supporting the positioning body portion on the magazine body, the positioning body can be more accurately positioned with respect to the photosensitive material conveyance path.
[0014]
[effect]
Therefore, in addition to the effects similar to those of the structure of the first aspect, the photosensitive material can be positioned more accurately in the width direction by the positioning operation body.
[0015]
The structure, operation, and effect of the invention according to claim 3 are as follows.
[0016]
[Constitution]
In the configuration of the invention according to claim 2, the support connection structure of the photosensitive material guide member and the predetermined positioning action part is formed on the engaged portion formed on the photosensitive material guide member, and the predetermined positioning action part is provided. The formed engaging portion is configured as an engaging connection structure that can be engaged.
[0017]
[Action]
In addition to having the same effect as that of the structure according to claim 2, the support connection structure of the photosensitive material guide member and the predetermined positioning action part is engaged with the photosensitive material guide member. Since the engagement connecting structure that can be engaged with the engaging portion formed on the predetermined positioning acting portion is formed on the portion, the support connecting structure can be prevented from becoming complicated, and for example, the position of the positioning acting body It is possible to easily perform change adjustment and attachment / detachment of the positioning body to / from the magazine body.
[0018]
[effect]
Therefore, in addition to achieving the same effect as the effect of the configuration of claim 2, the structure can be simplified, and the position changing operation of the positioning action body and the attachment and removal work of the positioning action body with respect to the magazine main body can be performed. We were able to improve work efficiency.
[0019]
The structure, operation, and effect of the invention according to claim 4 are as follows.
[0020]
[Constitution]
In the configuration of the invention according to claim 3, the positioning member is lifted and rotated around a predetermined axis on the bottom side in a state where the bottom portion of the positioning member is attached to the bottom portion of the magazine body. The engaged portion and the engaging portion are formed so as to be prevented by the engagement between the joint portion and the engaging portion.
[0021]
[Action]
In addition to being able to achieve the same operation as the operation according to the configuration of claim 3, in the state where the bottom portion of the positioning operation body is attached to the bottom portion of the magazine body, the positioning operation body is around a predetermined axis on the bottom side. It is possible to prevent the member from being lifted and rotated by the engagement between the engaged portion and the engaging portion.
[0022]
[effect]
Therefore, in addition to the effects similar to those of the structure of the third aspect, the photosensitive material can be accurately positioned in the width direction by the positioning operation body.
[0023]
