BACKGROUND OF THE INVENTION
In the present invention, a photosensitive material support portion for rotatably supporting a photosensitive material wound in a roll shape around a roll axis is provided in a magazine body, and the photosensitive material in a roll state or a photosensitive material in a fed state is provided in the width direction. A positioning action body that can be received from the outer side is provided on the positioning action body support portion on the magazine main body side so that the position change adjustment is possible in a direction corresponding to the width direction of the photosensitive material via a position change mechanism, and the position change is performed. The mechanism forms a predetermined number of grooves along a direction corresponding to the longitudinal direction of the photosensitive material on one side of the positioning action body support and the positioning action body, and on the other side, any groove This is related to a photosensitive material storage magazine in a photographic processor that is configured to have a locking projection that contacts the inner wall of the groove.
[0002]
[Prior art]
In a photosensitive material storage magazine in this type of photographic processor, positioning of a plurality of photosensitive materials having different widths is performed by adjusting the position of a positioning member in a direction corresponding to the width direction of the photosensitive material via the position changing mechanism. It corresponds to.
[0003]
Conventionally, as shown in FIGS. 10A and 10B, for example, the position changing mechanism is provided in the longitudinal direction of the photosensitive material on the left half and the right half of the guide base 15 as a positioning action member support portion. A groove group composed of a plurality of groove portions 26A, 26B, and 26C along the corresponding direction is formed, and any one of the groove portions 26A, 26B, and 26C is selected as a pair of left and right width restricting guides 13 as positioning members. Locking convex portions 27 that contact the inner walls of the groove portions 26A, 26B, and 26C are provided, and the position of the width regulating guide 13 is changed and adjusted as follows.
[0004]
[When a width a photosensitive material is positioned by the width regulation guide 13]
As shown in FIG. 10 (a), the surface f1 on one side of the locking convex portion 27 of the width regulating guide 13 (the surface on the side closer to the photosensitive material) is connected to one of the outer first groove portions 26A. The distance between the photosensitive material receiving surfaces of the pair of width regulating guides 13 is set to A corresponding to a.
[0005]
[When a width b photosensitive material is positioned by the width regulation guide 13]
As shown in FIG. 10 (b), the surface f2 on the other side of the locking convex portion 27 of the width regulating guide 13 is placed on one inner wall F1 of the second groove portion 26B adjacent to the first groove portion 26A. The distance between the photosensitive material receiving surfaces of the pair of width regulating guides 13 is set to B corresponding to b.
[0006]
[Problems to be solved by the invention]
Among the plurality of photosensitive materials, a pair of photosensitive materials having a small difference between the widths is usually one set or a plurality of sets, and the difference between the photosensitive materials may be only about 3 mm. In this case, the difference A−B between the distances A and B in the two positioning states is about 3 mm.
[0007]
By the way, when the width of the convex portion 31 between the first groove portion 26A and the second groove portion 26B is K and the width of the locking convex portion 27 is L in the conventional configuration, A−B = 2 (K + L). When AB is 3 mm as described above, one of the dimensions of K and L is 1 mm or less. However, with this type of locking structure, the width L of the locking projection 27 or both When the width K of the convex portion 31 between the groove portions 26 is 1 mm or less, there is a problem that the strength of the locking convex portion 27 or the convex portion 31 is weakened.
[0008]
Therefore, 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, corresponding to one photosensitive material, and corresponding to the other photosensitive material. Therefore, a means of using a different guide base 15 has been adopted.
[0009]
Therefore, in the conventional configuration, there is a problem that not only the number of guide bases 15 is increased and the manufacturing cost is increased, but also the replacement work is troublesome.
[0010]
The present invention has been made in view of the above circumstances, and an object thereof is to reduce the manufacturing cost and reduce the labor of the operator.
[0011]
[Means for Solving the Problems]
The structure, operation, and effect of the invention according to claim 1 are as follows.
[0012]
[Constitution]
In the photosensitive material accommodation magazine in the photographic processing machine described at the beginning, at least one of the inner walls of the predetermined groove portion in the position changing mechanism is formed in an uneven shape, and the groove portion A positioning state in which a convex portion receiving space for receiving a convex portion on the inner wall side 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 convex portion is moved from the positioning state to the photosensitive material. The convex portion on the inner wall side of the groove portion can be switched to a positioning state in which the convex portion is received in the convex portion receiving space.
[0013]
[Action]
According to said structure, a position change adjustment can be carried out as follows, for example of a pair of positioning action body provided with respect to the positioning action body support part.
[0014]
[When a photosensitive material having a width a is positioned by a positioning agent]
For example, as shown in FIGS. 6 and 7 (B), the locking projection 27 on the positioning action body 13 side (or positioning action body support section side) is connected to the positioning action body support section 15 side (or positioning action body side). The positioning effector 13 is positioned by contacting the convex surface of the inner wall of any one of the groove portions 26, and the photosensitive material having the width a is positioned in the width direction by the positioning effector 13 in this positioning state.
[0015]
[When locating photosensitive material of width b by positioning action body]
For example, as shown in FIGS. 6 and 7A, the locking projection 27 on the positioning action body 13 side (or the positioning action support section side) is moved in the direction corresponding to the longitudinal direction of the photosensitive material from the positioning state. And the convex portion 31 on the inner wall side of the groove portion 26 is received and positioned in the convex portion receiving space 28, and the photosensitive material having the width b is positioned in the width direction by the positioning operation body 13 in this positioning state. .
[0016]
In the above case, even if the height dimension of the convex part 31 on the inner wall side of the groove part 26 is set small, there is no problem such as a decrease in the strength of the groove part 26. Therefore, by setting the height dimension small, Further, it is possible to cope with the position change adjustment when the difference between the widths a and b is small.
[0017]
As a result, there is no need to prepare a plurality of sets of positioning operation body support portions 15 as in the prior art.
[0018]
[effect]
Therefore, the number of positioning action body support parts can be reduced as compared with the prior art, and the manufacturing cost can be reduced, and the positioning action body support part can be replaced with another positioning action body support part as in the past. The work to do is no longer necessary, and the labor of the operator can be reduced.
[0019]
The structure, operation, and effect of the invention according to claim 2 are as follows.
[0020]
[Constitution]
In the configuration of the invention according to claim 1, the side surface of the concave and convex portion of the inner wall of the predetermined groove portion is formed in a stepped shape, and the locking convex portion is positioned in a direction corresponding to the longitudinal direction of the photosensitive material from the both positioning states. It is configured to be able to switch to a positioning state in which the latching protrusion is brought into contact with the intermediate step on the side surface of the uneven portion by shifting.
[0021]
[Action]
In addition to the effects similar to the effects of the configuration of the first aspect, the following effects can be achieved.
[0022]
That is, when a photosensitive material having a width c that is an intermediate length between the width a and the width b is positioned by a positioning operation body, the locking projections on the positioning operation body side or the positioning operation body support portion 15 side are set to the both protrusions. The positioning working body is displaced from the positioning state in a direction corresponding to the longitudinal direction of the photosensitive material, and the locking convex portion is brought into contact with the intermediate step portion of the inner wall of the groove portion on the positioning body supporting portion side or the positioning body side. In this positioning state, the photosensitive material having the width c is positioned in the width direction by the positioning operation body.
[0023]
In this case, even if the height dimension from the convex surface of the convex part on the inner wall side of the groove part to the intermediate step part is set small, there is no problem such as a decrease in the strength of the groove part, so the height dimension is set small. By doing so, 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.
[0024]
[effect]
Therefore, it becomes easier to obtain the same effect as the effect of the structure of claim 1.
