The present invention relates to a photosensitive material storage magazine in a photographic processing machine, which has a configuration in which one of the grooves is selected and a locking projection is provided to abut on an inner wall of the groove.

[0002]

2. Description of the Related Art In a photosensitive material storage magazine of this type of photographic processor, a plurality of photosensitive materials having different widths are adjusted by changing the position of a positioning member in a direction corresponding to the width direction of the photosensitive material via the position changing mechanism. Of the photosensitive material.

Conventionally, the position changing mechanism is, for example, shown in FIG.
(A), as shown in FIG. 10 (B), a plurality of grooves 26A, 26B along the direction corresponding to the longitudinal direction of the photosensitive material are provided on the left half and the right half of the guide base 15 as the positioning action body support. , 26C, and a pair of left and right width regulating guides 1 as positioning members.
3 is formed by selecting one of the grooves 26A, 26B, and 26C and providing a locking projection 27 that is in contact with the inner wall of the groove 26A, 26B, 26C. The position was adjusted.

[When the photosensitive material having a width a is positioned by the width regulating guide 13] As shown in FIG. 10A, one surface f1 of the locking projection 27 of the width regulating guide 13 (of both surfaces) The surface near the photosensitive material) with the outer first groove 26
A is brought into contact with one inner wall F1 (the inner wall closer to the photosensitive material of the two inner walls), and the distance between the photosensitive material receiving surfaces of the pair of width regulating guides 13 is set to A corresponding to the a.

[When the photosensitive material of width b is positioned by the width regulating guide 13] As shown in FIG. 10 (b), the other surface f2 of the locking projection 27 of the width regulating guide 13 is connected to the first groove portion.

Set to the corresponding B.

[0006]

Generally, among the plurality of photosensitive materials, there is one or more pairs of a pair of photosensitive materials having a small difference in width, and the difference between the two photosensitive materials is small. May be only about 3 mm. In this case, the difference A−B between the distances A and B in the two positioning states described above.
B is also about 3 mm.

By the way, in the above-mentioned conventional structure, the first groove 26 is formed.
If the width of the protrusion 31 between A and the second groove 26B is K, and the width of the locking protrusion 27 is L, AB = 2 (K + L),
If AB is 3 mm as described above, one of the dimensions K and L becomes 1 mm or less. However, in this type of locking structure, the width L of the locking convex portion 27 or both When the width K of the protrusion 31 between the grooves 26 becomes 1 mm or less, the locking protrusion 27
Alternatively, there is a problem that the strength of the convex portion 31 becomes weak.

In order to cope with the positioning of a pair of photosensitive materials having a small difference between the widths, conventionally, a plurality of sets of guide bases 15 are prepared so as to correspond to one photosensitive material and to correspond to the other photosensitive material. In this case, a different guide base 15 is used.

For this reason, the conventional configuration has a problem that not only the number of the guide bases 15 is increased and the manufacturing cost is increased, but also the work of replacing them is troublesome.

[0010] The present invention has been made in view of the above circumstances, and has as its object to reduce the manufacturing cost and to reduce the labor of the operator.

[0011]

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

[Structure] In the photosensitive material accommodating magazine for a photographic processor, at least one of the two inner walls of the predetermined groove in the position changing mechanism is formed in an irregular shape, and the locking convex portion is provided. On the side, a convex portion receiving space for receiving the convex portion on the inner wall side of the groove portion is formed, and the locking convex portion is brought into contact with the convex surface of the inner wall of the groove portion, and the locking state is determined from this positioning state. The projection is shifted in a direction corresponding to the longitudinal direction of the photosensitive material so that the projection on the inner wall side of the groove can be switched to a positioning state in which the projection is received in the projection receiving space.

[Operation] According to the above configuration, for example, a pair of positioning members provided on the positioning member support portion can be changed and adjusted in the following manner.

[When the photosensitive material having the width a is positioned by the positioning member] For example, as shown in FIGS.
The locking projection 27 on the positioning action body 13 side (or the positioning action body support section side) is brought into contact with the convex surface of the inner wall of one of the grooves 26 on the positioning action body support section 15 side (or the positioning action body side). The positioning element 13 is positioned, and in this positioning state, the photosensitive material having the width a is positioned in the width direction by the positioning element 13.

[Positioning of a photosensitive material having a width b by a positioning member] For example, as shown in FIGS.
The locking projection 27 on the positioning action body 13 side (or the positioning action body support section side) is displaced from the positioning state in the direction corresponding to the longitudinal direction of the photosensitive material, and the projection on the inner wall side of the groove 26 is shifted. The portion 31 is received in the projection receiving space 28 for positioning. In this positioning state, the photosensitive material having the width b is positioned in the width direction by the positioning action body 13.

In the above case, even if the height of the convex portion 31 on the inner wall side of the groove 26 is set small, there is no problem such as a decrease in the strength of the groove 26. Therefore, the height is set small. By doing so, it is possible to cope with position change adjustment when the difference between the widths a and b is small.

As a result, there is no need to prepare a plurality of sets of the positioning member support portions 15 as in the prior art.

[Effect] Therefore, the number of positioning action support members can be reduced as compared with the prior art, and the manufacturing cost can be reduced. The work of replacing the working body support portion is not required, and the labor of the operator can be reduced.

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

[Structure] In the structure according to the first aspect of the present invention, the side surface of the concave and convex portion of the inner wall of the predetermined groove is formed in a step shape, and the locking projection is formed in the longitudinal direction of the photosensitive material from the both positioning states. , And can be switched to a positioning state in which the locking projection is brought into contact with an intermediate step on the side surface of the uneven portion.

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

That is, when the photosensitive material having a width c having a length between the widths a and b is positioned by the positioning member,
The locking projection on the positioning action body side or the positioning action body support section 15 side is displaced in the direction corresponding to the longitudinal direction of the photosensitive material from the two positioning states, and the locking projection is positioned on the positioning action body support section. The positioning member is positioned by abutting on the intermediate step of the inner wall of the groove on the side or the positioning member side, and in this positioning state, the photosensitive material having the width c is positioned in the width direction by the positioning member.

In this case, even if the height from the convex surface of the protrusion on the inner wall side of the groove to the intermediate step is set small, there is no problem such as a decrease in the strength of the groove. Is set small, it is possible to cope with the position change adjustment when the difference between the widths a and c or the difference between b and c is small.

[Effect] Therefore, the same effect as the effect of the first aspect can be more easily obtained.
