Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a holding structure in which a film cartridge used in an “advanced photo system” recently proposed can be easily attached and detached.
[0002]
[Prior art]
In the conventional 35 mm film photographic processing system, the negative film developed from the cartridge and processed is cut at an appropriate number of frames, stored in a negative sheet made of translucent film, and returned to the customer. The The customer stored the negative sheet separately using an empty box or the like, or stored it in an album together with a mount on which a negative was mounted and a photo was attached.
[0003]
By the way, the “advanced photo system” recently proposed is to shoot using a new standard film and a camera adapted to it instead of the conventional 35 mm film. Everything from the loading of the film into the camera to the development process after shooting is performed with the film stored in the cartridge.
[0004]
That is, the negative film after development is not stored in a negative sheet and returned in a flat state as in the prior art, but is returned to the customer in a state in which the negative film is stored in a long length in a film cartridge again. At this time, since the customer cannot directly check the contents of the negative film, each film cartridge is given a unique ID number, and all images appearing on the negative film and this ID number are printed on photographic paper. The “index print” is to be attached to this cartridge.
[0005]
The film cartridge will be further described. As shown in FIG. 2, the cross section protrudes in the diameter direction of the circle, and the columnar body has a rounded rhombus shape, and a part of one side protrudes as a film outlet 3a. The longest diagonal width (L1) is 30 millimeters, the high or shortest width (L2) is 21 millimeters, and the length (W) is 39 millimeters. Further, a unique ID number 3b is attached to the upper surface of the film outlet 3a, and a mark 3c indicating the use state of the film is attached to the side surface.
In the following description, as shown in FIG. 2, the upper and lower positional relationship is expressed with reference to the state where the ID number is located on the upper surface.
[0006]
[Problems to be solved by the invention]
As described above, in the new photo processing system, the negative film is not a flat negative sheet but is stored in a three-dimensional film cartridge and returned to the customer. There is a new need for a retaining structure to be applied.
[0007]
In general, as a means for storing and holding a three-dimensional object, for example, a storage recess that is slightly smaller than the size of the object is formed in a synthetic resin plate such as urethane so that the object is directly elastically fitted and sandwiched. Such a structure is employed, or a structure in which an object is dropped into a deep storage recess and a locking piece protrudes from the inside of the opening to prevent the object from being accidentally popped out.
[0008]
In these cases, since the object is held or locked by the elasticity of the material, the object must be pulled out by a force against the elastic force. For example, a fingertip enters one side of the storage recess as a means for taking out the object. It is necessary to provide a cutout of a size of a certain size or to provide a strip for each recessed portion of the storage, and the processing takes a lot of labor and cost. Also, when storing a large number of objects, it is necessary to secure a wide space between the storage recesses so that the objects do not interfere with each other and are easily picked up individually. There was a limit to the number of items that could be stored.
[0009]
The present invention pays attention to the shape of the film cartridge, and makes it possible to attach and detach the film cartridge very simply and reliably by the storage recess and the locking means corresponding to the shape, and when the storage board is provided with a plurality of storage recesses. Accordingly, the present invention intends to propose a holding structure that can accommodate a larger number of film cartridges by shortening the distance between them.
[0010]
[Means for Solving the Problems]
In view of the above circumstances, the present invention is such that the lower half of the film cartridge is fitted to the base plate made of synthetic resin in the same shape as the lower half of the film cartridge used in the advanced photo system, and the film cartridge is The storage recess is shaped so that an elastic force acts in the direction of pushing out, and a locking plate is erected in parallel with the storage recess with the protruding width of the film outlet of the film cartridge. The upper end of the plate facing the storage recess is provided with a locking protrusion that engages with the upper end corner of the film outlet of the film cartridge, and the film cartridge is formed by the locking protrusion and the opposite corner of the storage recess. The above-mentioned problem is solved by adopting a means of elastically holding the frame .
[0011]
Further, a means is adopted in which the length of the locking plate is made shorter than the length of the storage recess so that a part of the film outlet of the film cartridge to be fitted is exposed.
[0012]
The film cartridge holding structure having the above configuration is such that the film cartridge is fitted into the storage recess, and the film cartridge is elastically held between the locking protrusion provided on the locking plate and the opposite corner of the storage recess. is there.
Further, the engagement of the locking protrusion is released by pressing the locking plate or the film outlet exposed to the side of the locking plate, so that the film cartridge jumps out of the storage recess and is easily taken out.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the film cartridge holding structure according to the present invention will be described in more detail based on the embodiments shown in the drawings.
In FIG. 1, reference numeral 1 denotes a storage recess formed in a base plate P made of a synthetic resin plate. The shape of the storage recess is a lower half of the film cartridge 3 (a portion below the lower surface of the film outlet 3 a protruding in the horizontal direction). The opening width (d1) is slightly shorter than the shortest width (L2) of the film cartridge 3 so that the lower half of the film cartridge is completely fitted. . That is, the storage recess 1 does not hold the film cartridge 3 by itself, but rather the portion immediately below the film outlet 3a is rounded. As shown, the elastic force of the constituent material acts in such a direction that the film cartridge 3 is pushed out and the film outlet 3a faces upward.
[0014]
Reference numeral 2 denotes a locking plate which is erected in parallel with the longitudinal direction of the storage recess 1 with an interval of the protruding width of the film outlet 3a. A locking protrusion 2a is provided in the lateral direction on the storage recess side of the upper end. The upper end corner of the film outlet 3a is locked to restrict the film cartridge from popping out. That is, the distance (d2) between the locking protrusion 2a and the opposite corner 1a of the storage recess 1 is slightly shorter than the length of the corresponding portion of the film cartridge 3 to be fitted, and the ID number 3b is set higher. In this state, the film cartridge 3 is elastically sandwiched between the locking protrusion 2a and the opposite corner 1a of the storage recess.
[0015]
Further, the locking plate 2 may be the same length as the storage recess 1, but if a part of the film outlet 3 a is exposed as almost half the length of the storage recess 1, As will be described later, the engagement of the locking protrusions can be released by pressing the film outlet 3a.
[0016]
First, when the film cartridge 3 is accommodated, the holding structure having the above-described structure is such that the surface on which the ID number 3b is described is faced up as shown in FIG. 3A, and the film outlet 3a faces the locking plate 2. In this way, it is pushed into the housing recess 1. When the ID number portion is pressed as it is, the lower half of the film cartridge 3 is fitted into the storage recess, and the upper edge corner of the film drawing port 3a is engaged with the locking protrusion 2a of the locking plate 2, thereby The film cartridge 3 is held between the protrusion 2a and the corner 1a opposite to the housing recess 1 (see FIGS. 3B and 3C). In this case, the film cartridge can be easily identified because the ID number is on the top.
[0017]
When the film cartridge 3 is taken out, if the locking plate 2 is pressed with the fingertip in the direction opposite to the film cartridge (see FIGS. 4A and 4B), the engagement between the locking ridge 2a and the film outlet 3a. The film cartridge 3 pops out with the film outlet 3a up (see FIGS. 3C and 3D) by the elastic force of the storage recess 1 and can be easily taken out by pinching the outlet 3a. it can.
Further, even if the film outlet 3a exposed to the side of the locking plate 2 is slightly pressed with a fingertip to release the engagement with the locking protrusion 2a, it can be easily taken out by holding the outlet. it can.
[0018]
FIG. 5 shows an example in which the film cartridge holding structure is applied to a storage case with a lid. In the figure, 4 is a base box of the storage case, and 5 is a lid plate that is closed by a fastener 6. It is what I did. Reference numeral 7 denotes a storage board provided in the base box 4, in which storage portions 8 having the above-described holding structure are arranged in rows and columns (16 in the figure). As described above, according to the holding structure according to the present invention, since the film cartridge 3 is held with the ID number as the upper surface, the individual ID numbers 3b can be listed even in the housed state. Easy to search. In addition, since the film cartridge can be attached and detached very easily, even if the storage portions 8 are provided close to each other, only the desired film cartridge can be immediately removed without interfering with the adjacent film cartridge. It will be.
[0019]
The above holding structure is not limited to the above-described storage case. For example, as shown in FIG. 6, the storage board 9 with this holding structure is used as a mount shape together with a mount 10 for attaching a photograph. It is also possible to form a box album as a storage case 13 together with a plurality of pocket albums 12 as shown in FIGS.
[0020]
【The invention's effect】
As described above, the film cartridge holding structure according to the present invention can securely store and hold the film cartridge by a simple operation of pushing the film cartridge into the storage recess and pressing the film outlet from above, and using a fingertip. Since the film cartridge can be easily picked up simply by pushing the locking plate or the film pulling outlet to release the mutual engagement, the film cartridge can be easily attached and detached. Is.
[0021]
In addition, the film cartridge in the clamped state is not picked up directly, but is picked up in a free state in which the engagement is released with the fingertips. Even if the distance to the recess is short, the target cartridge can be reliably picked up without interfering with each other, and a large number of film cartridges can be stored and held in a limited space.
[0022]
Thus, since it has a very simple structure, it can be applied to an independent film cartridge storage case, and a storage board is provided on the mount and bound together with an album, or as a so-called box album together with a plurality of pocket albums. It is an excellent invention that can be expected to be applied in many ways.
