[Problems to be solved by the invention]
Recently, environmental data of products throughout the entire life cycle, from resource collection to manufacturing, logistics, use, and recycling of waste, has been obtained using LCA (life cycle assessment) methods, and quantitative environmental information on products has been disclosed in many ways. A new type of environmental label “Eco Leaf (ECO / LEAF)” is being displayed. The display of the Eco Leaf environmental label is actively implemented by companies that work on environmentally conscious products, thereby encouraging users to consider the environment when selecting and using products. In other words, communication regarding environmental information between the product provider and the user is promoted, and a trust relationship between the two is fostered, thereby contributing to the formation of a recycling-oriented society.
[0007]
In consideration of such operations, it is necessary to predict and evaluate in advance the content and extent of the impact on the environment when the product is disposed of, and environmental conservation measures, and to examine measures necessary for conservation.
[0008]
Both of the instant film packs (hereinafter referred to as film packs) described in the above-mentioned publications are instructed to be collected and recycled after use. However, since the photograph can be enjoyed on the spot, the instant film unit (hereinafter referred to as the film pack) Cases that remain after the film unit) is used up seem to be discarded as they are, and the recovery rate is low. Considering the impact of disposal on the environment, especially the soil, it was found that film covers and film unit pressing plates are made of plastic materials, which can have adverse effects, and environmental conservation measures were required. .
[0009]
Further, if the camera is left in a state where the pack is loaded in a closed car, the plastic member is deformed. For this reason, there is a possibility that inconveniences such as the film unit not being discharged in subsequent use may occur.
[0010]
An object of the present invention is to provide an instant film pack that is devised to use a material that does not deform even when placed in a high temperature environment and that is excellent in environmental conservation. And
[0011]
[Means for Solving the Problems]
In order to solve the above problems, the film pack of the present invention has a structure in which a film cover, a plurality of instant film units, and a film unit pressing plate are stored in a case, and the film cover or the film unit pressing plate is used as a paper. Made of made sheet. In consideration of environmental conservation, it is preferable to make the film cover and the film unit pressing plate with a paper sheet. In addition, the remaining cases other than the film unit are made of paper, making it a complete environmental conservation measure.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1 showing the structure of a film pack according to the present invention, a film pack 10 includes a case 11 having a vertically long rectangular parallelepiped shape, a film cover 12, a plurality of film units 13, and a film unit pressing plate 14. The case 11 includes a case main body 15 in which a plurality of film units 13 are stored in an overlapping manner, and a back cover 16 that covers the back surface thereof.
[0013]
The case main body 15 is formed of a material such as a thermoplastic resin or a paper resin obtained by mixing cellulose in a thermoplastic resin, and an exposure opening 17 for exposing the film unit 13 is formed on the front surface. The exposure opening 17 is provided with a notch 18 into which a known claw member provided in the camera enters. A slit-like discharge port 20 for discharging the exposed film unit 13 is formed on the upper surface of the case body 15. From the discharge port 20, the film unit 13 and the film cover 12 are discharged one by one.
[0014]
The discharge port 20 is closed from the outside with a soft light-shielding seal 21. Only one edge of the long side of the discharge port 20 is affixed to the light shielding seal 21 so as not to disturb the discharge of the film cover 12 and the film unit 13. The film cover 12 is overlaid on the film unit 13 that is initially set in the exposure opening 17 and closes the exposure opening 17.
[0015]
The film unit 13 has a thin, vertically long rectangular sheet shape, and is a self-development processing type in which a developer pod 13a, an exposure unit 13b, and a trap unit 13c are provided in this order from the longitudinal direction (discharge direction). It is a film. The exposure unit 13b includes a cover sheet, a photosensitive layer serving as an exposure surface, a white diffuse reflection layer, and an image receiving layer serving as a back surface. The developing solution pod 13a contains a developing solution. When the developing solution is spread between the photosensitive layer and the cover sheet, the latent image recorded on the photosensitive layer is transferred to the image receiving layer as a positive image through the diffuse reflection layer. The image transferred to the image receiving layer is observed as a positive image from the surface opposite to the exposure portion 13b. The trap part 13c develops between the photosensitive layer and the cover sheet from the developer pod 13a to capture and cure the remaining developing solution. The thickness of the exposure part 13b is thinner than the developer pod 13a and the trap part 13c. The film unit 13 is a mono-sheet type that can be handled as one sheet until the end.
[0016]
The back cover 16 is also formed of a material such as a thermoplastic resin or a paper resin in which cellulose is mixed with a thermoplastic resin. The back cover 16 is provided with a pair of openings 16a and 16b, a pair of unit support protrusions 16c and 16d, a pair of caulking pins 16e and 16f, and a support piece 16g, and a case so as to face the exposure opening 17. It is attached to the main body 15. The two openings 16a and 16b are provided on the upper and lower sides of the back cover 16 so as to be separated from each other by a predetermined distance, and serve as entrances when a push-up member provided in the camera enters when the camera is loaded. The pair of caulking pins 16e and 16f are for attaching the film unit pressing plate 14. The support piece 16g supports the central portion of the film unit 13 that is finally stacked, from behind, and prevents the film unit 13 from being bent in a direction in which the central portion curves toward the back cover 16.
[0017]
The unit support protrusions 16 c and 16 d are respectively provided vertically at both end portions of the back cover 16, and have a circular arc shape whose central portion protrudes toward the exposure opening 17. These unit support protrusions 16c and 16d are in contact with the left and right ends of the rearmost (last row) film unit 13 and push up the film unit 13 in a circular arc shape with the central portion projecting toward the exposure opening 17. Thus, a gap is prevented from being generated between the film cover 12 and the exposure opening 17.
[0018]
The film unit pressing plate 14 and the back cover 16 are attached by caulking. A pair of holes 14b and 14c are formed in the central portion 14a of the film unit pressing plate 14, and a pair of crimping pins 16e and 16f provided on the back cover 16 are inserted into the pair of holes 14b and 14c. Further, a horizontally long rectangular opening 14d is formed in the central portion 14a. The opening 14d is for inserting the support piece 16g.
[0019]
The film unit pressing plate 14 is made of paper having a light shielding property in which fibers are dyed in black and is formed in a vertically long rectangular sheet shape. Incisions 14e and 14f are provided in a straight line in the lateral direction above and below the central portion 14a. The notches 14e and 14f are for bending the upper and lower ends 14g and 14h sandwiching the central portion 14a toward the exposure opening 17 by pushing up the push-up member of the camera, respectively.
[0020]
The film cover 12 is made of a paper material having a light-shielding property in which fibers are dyed in black. The film cover 12 is formed as a vertically long rectangular sheet that is thinner than the maximum thickness of the film unit 13. ) The exposure opening 17 is closed by being stacked in front of the film unit 13 and stored in the case 11, and is discharged from the discharge port 20 by a claw member scraping operation provided in the camera after being loaded into the camera.
[0021]
The film cover 12 has a front end light shielding flap 12a formed of a light shielding material attached to a front end portion facing the discharge port 20. This front end light shielding flap 12a is bent in an L shape in the direction of the back cover 16, and the bent portion closes a part of the discharge port 20 from the inside to ensure the light shielding, and by an impact such as dropping. The film cover 12 and the film unit 13 are prevented from jumping out from the discharge port 20. A skirt 12 b for closing the notch 18 into which the claw member enters from the case 11 is attached to the rear end portion of the film cover 12.
[0022]
As shown in FIG. 2, the notches 14e and 14f of the film unit pressing plate 14 are provided above and below the center portion 14a. On each of the cuts 14e and 14f, it is desirable to provide intermittently, for example, 0.5 to 5 mm apart from each other with a constant pitch so that, for example, the remaining portions without entering the cut line can be positioned at two places. Note that. Instead of the cuts 14e and 14f, a perforation, a half cut, or a muscle push may be used.
[0023]
As shown in FIGS. 3 to 6, a pair of dimple portions 12 d and 12 e and ribs 12 f and 12 g protrude from the back surface 12 c of the film cover 12 (the surface facing the back cover 16) by embossing molding. ing. Each of the dimple portions 12d and 12e is a hemispherical convex portion at a region that is not exposed from the exposure opening 17 and at both upper ends (tips in the discharge direction). The dimple portions 12d and 12e have a protruding amount that has substantially the same thickness as the developer pod 13a of the film unit 13 including the thickness of the film cover 12. By doing so, it is possible to prevent the inconvenience of taking out the film unit 13 in the next layer together when the film cover 12 is discharged.
[0024]
The ribs 12f and 12g are formed to extend in a narrow band shape along the discharge direction. The planar strength of the film cover 12 is reinforced. When the film cover 12 is deformed in the thickness direction, gaps are formed at both ends of the exposure opening 17 to prevent outside light from entering the inside, and the film cover 12 is discharged. Sometimes the inconvenience of taking out the film unit 13 in the next layer together is prevented.
[0025]
The notch 18 provided in the case main body is formed across the exposure opening 17 from the bottom surface of the case main body 15 through the front surface, and is formed near one end in the width direction of the exposure opening 17. . The skirt 12b that closes this has a narrow strip shape elongated along the longitudinal direction of the film cover 12. The narrow band-like skirt 12 b is attached so that a part of the width direction protrudes along the end of the film cover 12 facing the notch 18 in the longitudinal direction, and the lower end also protrudes from the lower end of the film cover 12. . A cut line 12i (see FIG. 4) is formed at the lower end of the skirt 12b. When the skirt 12b is received in the case 11, the skirt 12b is bent in an L shape toward the back cover 16 to close the notch 18.
[0026]
As shown in FIG. 7, when the film cover 12 is housed in the case 11, a part of the skirt 12 b comes into contact with the inner wall of one side surface 15 a in the width direction inside the case main body 15, and the back cover 16. It is bent in an L shape toward As a result, the film cover 12 is moved toward the end opposite to the end where the skirt 12b is pasted by its own repulsive force (elastic force), and both the inner walls 15a, 15b of the case body 15 and both ends of the film cover 12 The gap is eliminated to prevent light from entering.
[0027]
Also, as shown in FIG. 8, the upper end 12j of the skirt 12b is attached from a position above the upper edge 17a of the exposure opening 17 when the case body 15 is viewed from the front. In this way, even if the film cover 12 is pushed from the exposure opening 17 and a gap is formed on the upper side between the exposure opening 17 and the inner wall 15a of the case body, the gap can be closed by the skirt 12b.
[0028]
As shown in FIG. 9, a dimple 12 h is formed at a lower portion of the film cover 12 at a portion facing the notch 18. The dimple 12h is formed so as to protrude in a semi-dome shape toward the exposure opening 17 so as to be easily caught by the claw member. As shown in FIG. 10, the claw member 40 moves straightly upward and scrapes the hooking portion 40 a from the exposure opening 17 toward the back cover 16. At this time, since the dimple 12h protrudes toward the exposure opening 17 from the film cover 12, the dimple 12h is easily caught by the hooking portion 40a, thereby reliably preventing the claw member 40 from being scraped off.
[0029]
Next, the operation of the above configuration will be described with reference to FIG. In the unused film pack 10, the exposure opening 17 is blocked by the film cover 12, the discharge port 20 is blocked by the light-shielding seal 21, and the openings 16 a and 16 b are blocked by the film unit pressing plate 14. Furthermore, the notch 18 is closed with the skirt 12b, so that the interior is completely shielded from light. Further, the unit support protrusions 16c and 16d are in contact with both ends of the back surface of the film unit 13 in the last row, and the entire film unit 13 is placed so that the unit support protrusions 16c and 16d push the exposure portion 13b against the exposure opening 17. Is pressed.
[0030]
When the back cover 46 provided on the camera 42 is opened and closed and the film pack 10 is loaded into the film loading chamber 43 of the camera 42, the push-up members 44 and 45 provided on the back cover 46 enter through the openings 16a and 16b to press the film unit. The plate 14 is pushed toward the exposure opening 17. As a result, the upper and lower ends 14g, 14h of the film unit pressing plate 14 are bent toward the exposure opening 17 from the cuts 14e, 14f, and the exposure unit 13b of the film unit 13 is further pushed up toward the exposure opening 17. Thereby, the flatness of the exposure part 13b of the frontmost film unit 13 and the adhesion to the exposure opening 17 are improved.
[0031]
After the film pack 10 is loaded into the film loading chamber of the camera and shutter release is performed to prepare for shooting, the claw member 40 enters the notch 18, the hooking portion 40a is caught by the dimple 12h, and the film cover 12 is placed at the discharge port 20. It is surely discharged toward. At this time, since the film cover 12 has the same thickness as the film unit 13 due to the dimple portions 12d and 12e provided at the left and right ends of the tip, the next-layer film unit 13 is not taken out together.
[0032]
The film cover 12 discharged from the film pack 10 comes into contact with the front end of the spread control member 48 and gently moves toward the developing roller pair 49 while the surface opposite to the exposure opening 17 is rubbed at the front end. Sent while curving. When the front end of the film cover 12 comes into contact with the outer peripheral surface of the developing roller pair 49, the film cover 12 is guided along the rotation direction of the developing roller pair 49 and is sent between the developing roller pair 49. 50 is discharged to the outside. As a result, the next film unit 13 is set in the exposure opening 17 and the preparation for photographing is completed.
[0033]
The film cover 12 is discharged while being deformed into an S shape by the spread control member 48, the developing roller pair 49, and the like. Further, the dimple portions 12d and 12e, the dimple 12h, and the ribs 12f and 12g are crushed by the developing roller pair 49. At this time, a load is applied to the motor for rotating the developing roller pair 49. However, since the film cover 12 is made of paper, it can be easily crushed, and therefore the load on the motor can be reduced.
[0034]
After the film cover 12 is discharged, the frontmost film unit 13 is set in the exposure opening 17. When the photographing range is confirmed with the finder and the shutter button is pressed, the shutter unit of the camera is activated and the exposure unit 13b of the film unit 13 is exposed. After the exposure is completed, the developing roller pair 49 starts to rotate almost simultaneously with the scraping operation of the claw member 40. When the film unit 13 exposed by the scraping of the claw member 40 is sent out from the discharge port 20, the surface opposite to the exposure surface is sent to the developing roller pair 49 while being squeezed by the spreading control member 48.
[0035]
The developing roller pair 49 cleaves the developer pod 13a of the film unit 13, and develops the developer flowing out from the developer pod 13a between the photosensitive layer and the cover sheet. Further, the spread control member 48 is in sliding contact with the film unit 13 being conveyed and spreads the developer uniformly. The film unit 13 in which the developing solution is developed by the developing roller pair 49 and the spreading control member 48 is discharged from the film outlet 50, and a positive image is formed on the positive image forming surface after a predetermined time. Excess developing solution is trapped in the trap portion 13c and hardened.
[0036]
If shooting is continued as described above, the remaining number of film units 13 stored in the case 11 decreases. At this time, the push-up members 44 and 45 of the camera 42 protrude by the thickness of the film unit 13 ejected by the bias of the spring and push the film unit pressing plate 14. As a result, even the last film unit 13 can be pushed up uniformly, and appropriate flatness can always be imparted to the film unit 13 set in the exposure opening 17.
[0037]
【Example】
The film unit 13 has a length of 85.6 × width 54 mm, the exposure portion 13 b has a size of 62.1 × width 46 mm, the developer pod 13 a has a thickness of 1.2 mm (maximum thickness), and the exposure portion 13 b has a thickness of 0. The thickness of the trap portion 13c is 33 mm. The dimensions of the case 11 are vertical 91 × horizontal 58.9 × thickness 19.6 mm (maximum thickness). The size of the exposure opening 17 is 66.3 × 48.9 mm.
[0038]
When the case 11 and the film unit 13 having the dimensions as described above are used, the film cover 12 has a thickness of 0.2 to 0.7 mm (basis weight 100 to 500 g / m) in consideration of elasticity, rigidity, light shielding property, and the like. ² ), preferably 0.3 to 0.5 mm (basis weight 300 to 400 g / m ² ).
[0039]
The height of the dimple portions 12d and 12e of the film cover 12 is preferably 0.5 to 1.5 mm including the thickness of the film cover 12. Further, the dimension of the dimple 12h is preferably a semi-dome shape having a width of 1 to 5 mm, and the height excluding the thickness of the film cover 12 is preferably 0.2 to 1 mm.
[0040]
The film unit pressing plate 14 has a thickness of 0.2 to 0.7 mm (basis weight 100 to 500 g / m ² ), preferably 0.3 to 0.5 mm (tsubo) in consideration of elasticity, rigidity, light shielding properties, and the like. The amount is preferably 300 to 400 g / m ² ).
[0041]
The material of the film cover 12 and the film unit pressing plate 14 may be made by applying a resin coating to paper so as to have elasticity, or by using resin-impregnated paper (impregnated paper). Other materials that can be used include PP-attached (polypropylene film-bonded paper) oil paper, wax-coated paper, and the like.
[0042]
In particular, the film unit pressing plate 14 is bent by the lifting members 44 and 45, and the film cover 12 is bent when passing through a pair of developing rollers provided in the camera. Therefore, the members 12 and 14 need to have rigidity (hereinafter referred to as bending stiffness) that indicates how much the members 12 and 14 are not bent with respect to the force to be bent. Therefore, as a result of experimenting by measuring bending stiffness (Taber) by the method specified in JIS: P8125, when using the above-mentioned dimensions, the material is such that the bending stiffness (B) satisfies 170 to 370 gf · cm. I found it necessary to choose. This is because, for example, in the case of the film cover 12, if the bending stiffness (B) is smaller than the value in the above range, there is a possibility that it will be difficult to discharge by the developing roller pair, and in the case of the film unit pressing plate 14, There is a possibility that the unit 13 cannot be pushed.
[0043]
In addition, the paper eyes include vertical eyes and horizontal eyes. Generally, the vertical eye is better than the horizontal eye,
1) Tear strength is low ... easy to tear along the vertical direction, or “flow line”,
2) Small expansion and contraction with respect to humidity,
3) Stiffness (rigidity / waist) is high,
4) The tensile strength is strong.
5) Elongation due to tension is small,
6) Folding strength is weak,
Etc.
[0044]
When the film cover 12 and the film unit pressing plate 14 are made of paper, in order to avoid the occurrence of a gap between the inner walls 15a and 15b of the case body 15 due to expansion and contraction with respect to the humidity in the width direction as much as possible, It is desirable to form a vertical line (a horizontal line in the discharge direction).
[0045]
This is because when the width dimensions of the film cover 12 and the film unit pressing plate 14 are determined in anticipation of an increase in the length in the width direction at a high temperature, the length in the width direction when the room temperature is reached becomes vertical in the discharge direction. The width is wider than that formed along the line. In other words, the one formed so that the vertical lines are aligned in the width direction has a smaller shrinkage rate in the width direction when the temperature is changed from high temperature to room temperature, thereby preventing light leakage in the width direction in the case 11. Because.
[0046]
Further, the film unit pressing plate 14 needs to have a property that the upper and lower ends 14g, 14h can be easily bent from the cuts 14e, 14f by inserting the lifting members 44, 45. However, if it is bent too much, there will be a disadvantage that light will enter when the fingers are carelessly inserted from the openings 16a and 16b of the back cover 16, and conversely, it will be difficult to bend the push-up members 44 and 45. Since it does not bend even when it is pushed up, there arises a disadvantage that the frontmost film unit 13 is not discharged. Therefore, it is desirable that the bending moment (M) of the force required for bending be 50 to 300 gf · cm (where (M) bending moment> (B) bending stiffness).
[0047]
Conventionally, since the film unit pressing plate described in Patent Document 1 or Patent Document 2 is made of a plastic material, the film unit pressing plate has a two-sheet configuration of a fixing sheet and a pressing plate. This is because when a film unit pressing plate is made of a plastic material by injection molding with a single sheet, as described above, the bending moment is molded to satisfy the properties of 50 to 300 gf · cm (very small). This is because it is difficult or has a defect in molding.
[0048]
This is because, in order to satisfy the above-described properties, it is important that the upper and lower ends in the discharging direction are bent toward the film unit 13 by pressing the push-up member of the camera. However, when it is made of a single material and made of a plastic material, if the portion to be bent is made thin or narrow, the resin hardly flows and a short shot is likely to occur. In addition, if a cut is made later in the molded plastic plate, the number of processes increases and the cost increases. Furthermore, even if post-processing is performed by thin-wall injection molding or incision, cracks are likely to occur when bent, and there is a risk that they will break if they enter.
[0049]
For this reason, when it is made of paper, the cuts 14e and 14f can be easily made and, at the same time, the punching of the outer shape can be performed at the same time, so there is an advantage that the cost can be reduced. In addition, there is an advantage that the paper is less likely to be cut just by being bent.
[0050]
In the above embodiment, the transmissive film unit having a different exposure unit 13b and positive image forming surface has been described as an example. However, a reflection type film unit having the same exposure unit 13b and positive image forming surface is used. It can also be applied to a film pack to be stored. It can also be used in printers that use film packs.
[0051]
【The invention's effect】
As described above, the instant film pack of the present invention does not deform even when placed in a high temperature environment because the film cover or the film unit pressing plate is formed of a paper material. It is safe for the environment even if it is disposed of.
