Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film-integrated camera.

[0002]

2. Description of the Related Art A film-integrated camera (trade name "Sharing Run" etc.) which is widely sold by the applicant of the present invention has an unexposed film preloaded in a unit body incorporating a simple photographing mechanism and a winding mechanism. It is sold in the state of being sold, and after use, the entire unit body is collected at the developing station. After disassembling the main unit of the unit at the photo lab, the exposed film is taken out for development and printing, but the main unit itself is not returned to the user. From such a background, the film built into the film-integrated camera is
A dedicated film can be used.

By the way, the film which is conventionally built in the film-integrated camera is the one defined by the international standard.
It is a 35-type color negative film. This color negative film is provided for various sensitivities so that it can be mounted on any camera and according to the photographer's application. The general-purpose color negative film has a structure in which each photosensitive layer sensitive to blue, green, and red photosensitive areas is a blue-sensitive layer, a green-sensitive layer, and a red-sensitive layer in that order from the exposed surface. The spectral sensitivity characteristics are different from each other. The silver halide used as a constituent material of these photosensitive layers is generally a silver iodide emulsion, which has high sensitivity to blue light. Therefore, the sensitizing dye is added during the production of the emulsion, and a yellow filter layer that absorbs blue light is provided below the blue layer to keep the sensitivity balance of each photosensitive layer constant. Therefore, the cost of the color negative film is high due to the processing for keeping the sensitivity balance of each photosensitive layer constant, and the cost is reflected in the price of the film-integrated camera. It is strongly desired to make a low-cost film in a film-integrated camera, because it is not necessary to load a dedicated color negative film to keep the balance of the sensitivity of the built-in film constant.

As a support for the film incorporated in the above-mentioned film-integrated camera, it is required to use a support which is transparent and has excellent film strength. Cellulose-based nitrocellulose and triacetylcellulose have been conventionally used as materials satisfying those requirements, and in recent years, polyethylene terephthalate has been rapidly introduced.
Particularly, polyethylene terephthalate is useful from the viewpoint of dimensional stability and thinning, because it is excellent in water resistance and film strength.

However, polyethylene terephthalate has a drawback that its winding habit is very likely to occur when it is wound in a roll form for a long time or exposed to a high temperature (for example, in a car on a midsummer day). For this reason,
In JP 51174, the improvement is achieved by exposing a roll made of polyethylene terephthalate to an atmosphere kept at a temperature higher by 15 to 35 ° C. than the winding temperature on a slit roll for 24 hours or more. In addition, JP-A-5
In Japanese Patent Laid-Open No. 0-95374, the planarity is improved by heat aging the polyester film (polyethylene terephthalate) heat-fixed after biaxial stretching in the temperature range of 40 ° C to 130 ° C. However, even if it is attempted to remove the curl by these heat treatments, if it is left in the above-mentioned high temperature (80 ° C. or higher) state for a long time, it has no effect and is a problem in practice. That is, normal 35m
The color negative film having polyethylene terephthalate as a support, which had been heat-treated under the above conditions, was wound into an m-film patrone, and the film was left at 80 ° C for 2 hours and then taken out from the cartridge. It has not been demonstrated at all. As a result, transport problems occur in the automatic processor,
In addition, a bad effect that the flatness of the color negative film is poor at the time of printing is exhibited. Therefore, it is still desired to improve the curl habit of the support of the film incorporated in the film-integrated camera.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and the first object of the present invention is to:
It is to provide a film-integrated camera with a built-in low-cost negative film, and to provide a film-integrated camera at low cost. A second object is to provide a film-integrated camera having a built-in negative film that is hard to be rolled. A third object is to provide a film-integrated camera having a built-in negative film that excels in passing through a minilab and facilitates tongue tip extraction work.

[0007]

An object of the present invention is to wrap an unexposed film drawn from a patrone into a supply chamber, load an empty patrone into the winding chamber, and take the unexposed film for each photographing. In the film-integrated camera configured to be pulled out from the supply room and rolled up in the cartridge, the plastic lens contains at least one kind of ultraviolet absorber, and the support of the unexposed film is polyethylene naphthalate or its derivative. Achieved by a film-integrated camera, which is characterized by: The unexposed film is loaded in the film-integrated camera in a state where the central portion is empty or is wound on a spool.

The ultraviolet absorber contained in the plastic lens used in the film-integrated camera of the present invention will be described below. However, the ultraviolet absorber is not particularly limited as long as it has an absorption peak in the ultraviolet region (200 to 400 nm).

However, among them, the polyethylene naphthalate of the present invention has an absorption wavelength of up to 380 nm, so that an ultraviolet absorber having sufficient absorption up to a long wavelength region (300 to 400 nm) is preferable. Particularly preferred UV absorbers are represented by the following general formulas [I] to [VI]

PBB-8: PEN / PET / PAr (50/25 / 25) Tg = 108 ° C

Further, one of the properties which are problematic when using polyethylene naphthalate and its derivatives as a support for photographic light-sensitive materials is the problem of fogging caused by the high refractive index of the support. . The refractive index of polyethylene naphthalate and its derivatives is 1.6 to 1.
7 is high, the refractive index of gelatin which is the main component of the photosensitive layer coated thereon is 1.50 to 1.55, which is smaller than this value. Therefore, when light enters from the film edge, it is easily reflected at the interface between the base and the emulsion layer. Therefore, the polyester film causes a so-called light piping phenomenon (fogging). As a method of avoiding such a light piping phenomenon, a method of incorporating inert inorganic particles and the like into a film, a method of adding a dye, and the like are known. The preferred method for preventing light piping in the present invention is a method by adding a dye that does not significantly increase film haze. The dye used for film dyeing is not particularly limited, but the color tone is preferably gray dyeing due to the general property of the light-sensitive material, and the dye is excellent in heat resistance in the film forming temperature range of polyester film, and polyester Those having excellent compatibility with are preferable. From the above viewpoints, as the dye, it is possible to achieve the object by mixing commercially available dyes for polyester such as Diaresin manufactured by Mitsubishi Kasei and Kayaset manufactured by Nippon Kayaku. Regarding the dyeing density, the color density in the visible light region was measured with a color density meter manufactured by Macbeth Co.
It is necessary to be above. More preferably 0.03
That is all.

The polyester film according to the present invention can be imparted with slipperiness depending on the application, and the slipperiness imparting means is not particularly limited.
The kneading of an inert inorganic compound or the coating of a surfactant is used as a general method. Such inert inorganic particles include SiO ₂ , TiO ₂ , BaSO ₄ , CaC.
Examples are O ₃ , talc, kaolin and the like. Further, in addition to the slipperiness imparted by an external particle system in which inert particles are added to the polyester synthesis reaction system described above, a slipperiness imparting method by an internal particle system in which a catalyst or the like added during the polyester polymerization reaction is precipitated can also be adopted. Is. These slipperiness imparting means are not particularly limited, but transparency is an important requirement for a support for a photographic light-sensitive material. Therefore, in the slipperiness imparting method means, a polyester film is used as an external particle system. It is desirable to select SiO ₂ having a refractive index relatively close to that, or an internal particle system capable of relatively reducing the precipitated particle size. Further, in the case of imparting slipperiness by kneading, a method of laminating a layer imparted with a function in order to obtain more transparency of the film is also preferable. Specific examples of this means include a co-extrusion method using a plurality of extruders and feed blocks, or a multi-manifold die.

Furthermore, the polyethylene naphthalate and the derivative thereof of the present invention may contain an ultraviolet absorber of the general formulas [I] to [VI], and a method for preparing the same will be described below. The polyethylene naphthalate and its derivative of the present invention can be uniaxially or biaxially stretched after film formation according to a conventional method to obtain the support of the present invention having a target thickness. The preferable thickness of the support of the present invention is 50 μm to 90 μm. If it is 50 μm or less, it cannot withstand the shrinkage stress of the photosensitive layer generated during drying, while if it is 90 μm or more, it contradicts the purpose of reducing the thickness for compactness.

The polyethylene naphthalate and its derivative of the present invention, when used for photographic use, are used in combination with an emulsion layer (mainly gelatin type binder) and a back layer (gelatin type, cellulose type, polyester type or vinyl polymer type binder). Various surface treatments and undercoating treatments are performed to improve adhesion. For example, chemical treatment, mechanical treatment, corona discharge treatment, flame treatment, ultraviolet treatment, high frequency treatment, glow discharge treatment, active plasma treatment, laser treatment, mixed acid treatment, ozone oxidation treatment, etc. A photographic emulsion may be applied to obtain an adhesive force, or an undercoat layer may be provided and a photographic emulsion layer may be applied thereon after the surface treatment of these materials or without surface treatment. The undercoating liquid may contain various additives as required. For example, surfactants, antistatic agents, antihalation agents, coloring dyes, pigments, coating aids, antifoggants and the like. When the undercoating liquid of the present invention is used, an etching agent such as resorcin, chloral hydrate, chlorophenol and the like can be contained in the undercoating liquid. The undercoat layer of the present invention may contain inorganic fine particles such as SiO ₂ and TiO ₂ or polymethylmethacrylate copolymer fine particles (1 to 10 μm) as a matting agent.

The undercoating liquid according to the present invention is a well-known coating method such as dip coating method, air knife coating method, curtain coating method, roller coating method, wire bar coating method, gravure coating method, or US Pat. It can be applied by the extrusion coating method using the hopper described in the specification of 2,681,294. If desired, US Pat. No. 2,761,791

Two or more layers can be simultaneously coated by the method described in “Coating Engineering”, page 253 (1973, published by Asakura Shoten). After the film formation, the support coated with the undercoat liquid may be biaxially stretched (for example, the length and width are each 3
It is also possible to apply an undercoat liquid on a uniaxially stretched support and then further stretch the coating biaxially to provide an undercoat layer on the support of the present invention having a target thickness.

Preferred undercoating binders are nitrocellulose, gelatin, vinylidene chloride and ethylenically unsaturated ester in an amount of 35 to 96% by weight and 3.
Examples thereof include polymers or latices containing 5 to 64.5% by weight and 0.5 to 25% by weight of an acid component (for example, itaconic acid, itaconic acid half ester, acrylic acid, methacrylic acid).

The present invention will be described in detail below with reference to examples, but the present invention is not limited thereto.

(Embodiment 1) In FIG. 2 showing the external appearance of a film unit with a lens, a unit main body 1 light-tightly closes a main body base 2 made of plastic and an opening on the back side of the main body base 2. It consists of a case back 3.
The main body base 2 is provided with a taking lens 4, a finder window 5, a release button 6, and a film winding dial 8 which are molded from the plastic containing the ultraviolet absorbent according to the present invention, and as shown in FIG. A shooting mechanism such as a shutter mechanism 11 interlocking with the operation of the release button 6 and a film winding mechanism (not shown) interlocking with the operation of the film winding dial 8 is incorporated. The case back 3
Is fixed to the back side of the main body base 2, and a film 12 with a cartridge is light-tightly housed between them, as shown in FIG.

In the film 12 with a cartridge, a cartridge 13 for preliminarily storing the film 14 having a width of 35 mils in a light-shielded state at the time of assembling, and a roll-shaped film 14 pulled out from the cartridge 13 are attached to the main body base 2. The film roll chamber 15 with the exposure frame 17 provided therebetween,
And the cartridge chamber 16 respectively. The film 12 with a patrone used here is a 135 type color negative film defined by the international standard.

As shown in FIG. 3, the film 14 includes a blue-sensitive layer 20, a green-sensitive layer 21, and a red-sensitive layer 2 having different spectral sensitivity characteristics.

1 and 22, the specific sensitivity of the blue sensitive layer 20 is the other photosensitive layer 21,
It is a film dedicated to the film unit with a lens different from 22. This is because each photosensitive layer 20,
This is a low-cost type film produced without performing a process for making the sensitivity balance of 21 and 22 constant, and the blue sensitive layer 20 has a higher sensitivity than the other photosensitive layers 21 and 22. In addition, the specific sensitivity of the blue sensitive layer 20 is set to the other photosensitive layer 2
It is preferable to manufacture the film 14 in a state of being higher than 1 and 22 because the blue sensitive layer 20 is applied to the most exposed surface of the film 14 because it is relatively easy to process.

ANSI (American Na)
regional Standards Institute
e, Inc. ) In the standard, the sensitivity of the film 14 is determined based on the specific sensitivity between the green-sensitive layer and the red-sensitive layer. Therefore, the relative sensitivity between the green-sensitive layer 21 and the red-sensitive layer 22 in the photosensitive layer is determined. Even in the film 14 in which the specific sensitivity of the blue sensitive layer 20 is set to be 1.6 to 4 times that of the other photosensitive layers 21 and 22 while being substantially the same, the specific sensitivity of the green sensitive layer 21 and the red sensitive layer 22 is the same. It can be displayed as a sensitivity of 14.

As shown in FIG. 1, a filter 24 is provided behind the taking lens 4, but the filter 24 may be omitted. The filter 24 has a spectral transmission characteristic of dimming in the wavelength range of the blue-sensitive layer 20, as shown in FIG. 4, in order to compensate for the different specific sensitivities of the blue-sensitive layer 20. The material of the filter 24 may be a gelatin filter, an interference filter, etc. in addition to the glass filter and the plastic filter.

Next, the operation of the film-integrated camera will be briefly described. When the release button 6 is operated, the shutter of the shutter mechanism 11 opens and closes, the subject light that has passed through the taking lens 4 passes through the filter 24, and the subject light that has passed through the filter 24 is located in the exposure frame 17
4 is incident and exposure is performed.

The subject light transmitted through the plastic taking lens 4 and the filter 24 is about 3 as shown in FIG.
The light is incident on the film 14 after being dimmed in the wavelength range of about 00 to 500 nm, and the spectral sensitivity characteristic of the film 14 is shown in FIG.
As shown in (4), the blue sensitive layer 20 which is sensitive to a wavelength range of about 300 to 500 nm has a higher specific sensitivity than the other photosensitive layers 21 and 22, and thus is appropriate in terms of color sensitivity. After that, when the winding knob 8 is rotated, the exposed film is wound into the cartridge 13. At the same time, the next film frame is supplied to the position of the exposure frame 17 and is fed one frame at a fixed length.

By repeating the photographing in this way, the exposed film is successively wound into the cartridge 13. And after completing the shooting,
It is submitted to the photo lab as it is. When the processing is performed in the developing place, the photographed patrone can be taken out in the same state as the conventional one, and thereafter, the film development and the print processing can be performed by the conventional processing.

It is known that when the blue color is strengthened with respect to red and green, the color of the finished printed photograph may have a margin, but in consideration of this, the spectral characteristics of the plastic lens 4 or the filter 24. Can also be adjusted.

A negative film having polyethylene terephthalate and polyethylene naphthalate as a support was used in the film-integrated camera of the present invention, and after processing, the results of color development processing are shown in Example 2.

Of the same length (corresponding to 36 frames taken), and further perforated and incorporated into the units described in JP-A-1-224750 and 4-40438. The former is a unit in which the center of the unexposed film is wound in the air (see FIGS. 5 and 6). The lens of the film-integrated camera of the present invention used for the evaluation is shown in Table 2. Injection molding was performed using a resin and an ultraviolet absorber, and then annealing was performed to form a plastic lens. Next, the film-integrated camera of the present invention was heated at 80 ° C. for 2 hours, and the film was wrapped around the film. This temperature condition is a condition assuming that the film was placed in the automobile during the daytime in summer. 3 Extraction of tongue and development processing After the film-integrated camera loaded with the film wrapped under the above conditions was allowed to cool overnight in a room at 25 ° C,
The tongue was pulled out by a jig, and this film was developed by an automatic processor (Minilab FP-550B: manufactured by Fuji Photo Film). The development processing conditions are as follows.

As described above, according to the film-integrated camera of the present invention, at least one of a plurality of photosensitive layers having different spectral sensitivity characteristics has a specific sensitivity different from that of the other photosensitive layers. Since the image is taken through a filter with a spectral transmission characteristic that supplements different specific sensitivities or a photographic lens, the cost of the film to be built in is not processed to make the sensitivity balance of each photosensitive layer constant during film production. A special type of film can be used. Therefore, the cost reduction of the lens-equipped film unit itself can be improved. Further, according to the present invention, it is possible to obtain a film-integrated camera which is hard to have a curling tendency at high temperature, is easy to pull out the tongue end of the film, has good minilab passing property, and has less fog.
