Abstract

PROBLEM TO BE SOLVED: To obtain a positive film frame holding frame which makes positive film frame numbers immediately identifiable. SOLUTION: The positive film frame holding frame 10 is formed of a pedestal 12 in opaque color and a cap 14 in transparent color by two-color molding. The positive film frame number is therefore visible through the cap 14. Then, when the positive film frame 22 is printed, the rear and front of the positive film frame 22 are discriminatable by the positive film frame number and the erroneous printing of the positive film frame 22 reverse in the front and the rear does not occur. Since the rear and front of the positive film frame 22 are made easily identifiable by the positive film frame number, workability is good. Even when the positive film frame 22 is projected, the pedestal 12 is molded in the opaque color and therefore the light is shielded by the pedestal 12 and the segments exclusive of an image part 26 are prevented from being projected.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a positive film frame holding frame in which a positive film frame number can be easily identified.

[0008]

According to the first aspect of the present invention, a positive film frame is mounted on the pedestal. A lid is engaged with the pedestal by an engaging means, and the pedestal and the lid hold the positive film frame. At this time, the image portion is exposed from the window. Here, at least one of the pedestal and the lid has a transmittance such that the number assigned to the positive film frame can be determined.

As described above, since the positive film frame number can be determined, the front and back of the positive film frame can be immediately identified by the positive film frame number. For this reason, there is no possibility that the positive film frame is printed upside down.

In addition, the work of judging the front and back of a positive film frame by looking at the image portion requires the skill of an operator. However, the work of judging the front and back of a positive film frame by looking at the positive film frame number is required. The skill of the worker is not required.

For this reason, there is no variation due to the operator.
Anyone can easily judge the front and back of a positive film frame, so workability at a photo lab is good. Further, since the positive film frame number can be determined through the pedestal or the lid, it is not necessary to take out the positive film frame from the positive film frame holding frame for the determination.

Here, for example, the lid is molded in a transparent color.
Thereby, the positive film frame number can be seen through the lid. Also, in this case, by molding the pedestal in an opaque color, even when projecting a positive film frame with a slide projector or the like, portions other than the image portion are shielded from light by the pedestal, so portions other than the image portion are projected. Never.

According to the second aspect of the present invention, the lid and the pedestal are connected by a hinge, and the pedestal and the lid are rotatably supported. As described above, since the lid and the base are integrated by the hinge portion, the number of parts is small,
Also, since there is no displacement between the lid and the pedestal, workability is good.

According to the third aspect of the present invention, the engaged portion is formed on at least one of the base and the lid. On the other hand, the light-blocking member provided with the window for exposing the image portion has an engaging portion that can be engaged with the engaged portion.

As described above, since the light-blocking member can be engaged with at least one of the pedestal and the lid, the pedestal and the lid can be molded in a transparent color. Manufacturing costs are reduced.

[0016]

1 and 2 show a holding frame 10 for a positive film frame according to the present embodiment.

The holding frame 10 for a positive film frame has a thin, substantially square shape, and includes a pedestal 12 and a lid 14. The pedestal 12 and the lid 14 are connected to the thin hinge 1
The lid 14 is rotatable with respect to the pedestal 12 around the hinge 16.

As described above, since the lid 14 and the pedestal 12 are integrated by the hinge portion 16, the number of components is small, and when the lid 14 is rotated, there is no displacement with the pedestal 12. Good workability.

The holding frame 10 for positive film frames is
The base 12 is made opaque and the lid 14 is made transparent by color molding. Openings 18 and 20 are formed in the center of the pedestal 12 and the lid 14, respectively, with the same size.
When the pedestal 12 and the lid 14 are overlapped, they are arranged at the same position.

Here, a plurality of perforations 24 are formed at regular intervals at the widthwise end of the positive film frame 22, and an image portion 26 on which an image is recorded at a position determined by these perforations 24. Is formed, and at the extreme end in the width direction of the positive film frame 22,
The positive film frame number (here, the thirteenth number) serially assigned to the positive film frame 22 is described.

On the other hand, the size of the openings 18 and 20 is slightly smaller than that of the image section 26, and a recess 30 is formed around the opening 18 along the opening 18. The outer periphery of the recessed portion 30 is
The positive film frame 22 is slightly larger than the outer circumference of the positive film frame 22, and the positive film frame 22 is positioned in accordance with the recess 30. The positive film frame 22 thus positioned is placed in the image section 2.
6 is located in the opening 18, and the positive film frame number is located in the depression 30.

In this state, when the lid 14 is engaged with the pedestal 12 (described later), the image section 26 is exposed, and
4 is molded in a transparent color, so that the positive film frame number can be seen through the cover 14. For this reason, when printing the positive film frame 22 in the developing laboratory, the front and back of the positive film frame 22 can be determined by the positive film frame number.

Therefore, there is no possibility that the positive film frame 22 is erroneously printed upside down. Further, since the positive film frame number can be seen through, there is no possibility that the customer mistakes the positive film frame 22 for which printing is desired.

Further, in the conventional operation of judging the front and back of the positive film frame 22 by looking at the image portion, the skill of the operator is required. The skill of the operator is not required for the work of judging the front and back.

Therefore, there is no variation due to the operator,
Since anyone can easily determine the front and back of the positive film frame 22, the workability in the developing laboratory is good. Furthermore, since the positive film frame number can be determined through the pedestal 12 or the lid 14, it is not necessary to take out the positive film frame 22 from the positive film frame holding frame 10 to make the determination.

When projecting the positive film frame 22 using a slide projector or the like, the pedestal 1
Since 2 is molded in an opaque color, it is shielded from light by the pedestal 12 and only the image section 26 transmits light, so that parts other than the image section 26 are not projected.

Here, the engagement means will be described. A plurality of bosses 34 are formed around the recess 30. On the other hand, on the lid 14 side, a plurality of small-diameter bosses 32 are formed at positions corresponding to the bosses 34 when the lid 14 is rotated. The outer diameter of the small-diameter boss 32 is substantially the same as the inner diameter of the boss 34, and the small-diameter boss 32 and the boss 34 are engaged when the lid 14 is rotated about 180 degrees.

As described above, by engaging the small diameter boss 32 with the boss 34, the positive film frame 22 located between the pedestal 12 and the lid 14 is held without displacement. Also,
A wall 12 </ b> A stands upright from an edge of the pedestal 12, and an inner peripheral wall of the wall 12 </ b> A is substantially the same as a peripheral wall of the lid 14.

For this reason, when the lid 14 is rotated, the lid 14 is stored along the inner peripheral wall of the wall 12A. The height of the wall 12A is substantially the same as the thickness of the lid 14, and when the lid 14 is closed, the distal end surface of the wall 12A is flush with the lid 14.

On the other hand, an engaging hole 3
The cover 14 is provided with an engagement projection 38 corresponding to the engagement hole 36 when the cover 14 is rotated. The engagement protrusion 38 is provided in the engagement hole 36.
The vertical direction of the positive film frame holding frame 10 can be determined by the engaging holes 36.

The pedestal 12 and the lid 14 are made of a soft synthetic resin, and the pedestal 12 and the lid 14 can be bent. For this reason, the height of the small diameter boss 32 is
When the pedestal 12 and the cover 14 are bent, the pedestal 12 and the lid 14 are separated from the boss 34 so that the positive film frame 22 can be removed from the positive film frame holding frame 10.

Here, the holding frame 10 for positive film frames is molded in two colors, and the pedestal 12 is made opaque and the lid 14 is made transparent. However, the present invention is not limited to this. The cover 14 may be made opaque, or the positive film frame holding frame 10 may be entirely molded in a transparent color.

As described above, the positive film frame holding frame 1
By molding all 0's in a transparent color, the molding time is reduced and the manufacturing cost is reduced. In this case, when projecting the positive film frame 22 with the slide projector, the optical path may be blocked by masking with a seal or the like.

In the present embodiment, the lid 14 is made transparent, but it is sufficient that the lid 14 has a degree of transparency capable of discriminating the positive film frame number.

Further, as shown in FIGS. 3A, 3B and 4, a light-blocking member 44 may be used to engage with the back surface of the pedestal 40. In this case, an opening 48 is formed at the center of the light shielding member 44 so as to face the opening 46, and a plurality of projections 52 that can engage with the boss 50 formed on the pedestal 46 are formed around the opening 48. Form.

On the other hand, the pedestal 40 penetrates the boss 50,
The small-diameter boss 54 formed on the lid 42 and the projection 52 formed on the light shielding member 44 can be engaged with the boss 50, respectively.
