Abstract

PURPOSE:To reduce the driving resistance at the time of sending out a film after development processing by setting the coefficients of static friction of both surfaces of the silver halide photosensitive material after development processing to less than a specific value. CONSTITUTION:A film sending-out function is provided in the cartridge 1 and the coefficients of static friction of both the surfaces of the photosensitive film 3 after development processing are set to <=0.25. Thus, the coefficients of static friction are decreased to reduce the friction between the emulsion surface and back surface of the film, a cartridge inside surface and the film, and further the film and a cartridge exit part when the film is send out of the cartridge by spool rotation, and consequently the driving torque is reduced to prevent the film from flawing. A lubricant is preferably incorporated in the emulsion layer and back layer of the film and specially in the outermost layers on both the surfaces so as to set the coefficients of static friction of the photographic film after development processing to <=0.25.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a developed silver halide photographic material (hereinafter referred to as photographic film, photographic material or film) which is wound into a roll on a spool and stored. ) concerning a photographic film cartridge with

(Conventional technology) After conventional photographic film is photographed, it is developed in a developing laboratory, and in the case of negative film, the negative sheet is cut into pieces every few frames and stored in a sheet called a negative sheet, which is then returned to the customer. .This method has long been considered common sense in the photography industry.

Indeed, this method has been used for many years and has been used to organize photographic film.

However, when these negative sheets are printed simultaneously during development processing, they are rarely used again, and customers often discard them because they are cumbersome to store. Furthermore, the information of negative photosensitive materials stored in the form of negative sheets is rarely used in other video equipment, and even if they are, they are stored in a very special form (for example, once digitally transferred to a floppy disk, it can be used on a TV screen). (shown above).

For these conventional negative sheet storage formats, patent application No. 1-
A method has been proposed in which a storage container (patrone) described in No. 21862 is used to store a developed photosensitive material in the cartridge.

This method not only allows the developed film to be rolled up from inside the cartridge, but also to be sent out.Thereby, the developed film can be stored, and the sent out video information can be taken out as needed. In this way, the cartridge that can store developed film makes it easier and shorter to store developed film, and by making negative film cartridge and developed film cartridge into the same cartridge, cartridges that were previously discarded can be saved. environmental conservation and cost reduction.

(Problem to be Solved by the Invention) However, by using the cartridge described in Japanese Patent Application No. 1-21862, there is no need to load film into the film feed mechanism when shooting with a camera, and developed film This not only makes it easier for the customer to organize and store the film (it also makes processing such as reprinting easier later on, but it also makes it easier to output the developed film to video equipment such as a TV). When feeding the leading end of the film out of the cartridge, the drive energy required to rotate the spool increases, causing the battery to run out quickly, or the film may bend inside the cartridge. Because they are pressed together so strongly, scratches tend to stick to the surface, resulting in scars on the image, which poses a problem.

(Object of the Invention) A first object of the present invention is to provide a cartridge incorporating a film with reduced driving resistance when rotating the spool to feed out the developed film.

A second object of the present invention is to provide a cartridge containing a developed film that does not cause scratches when the film is fed out by rotating the spool.

(Means for Solving the Problems) These objects of the present invention are such that, by rotating a spool rotatably provided in the cartridge main body in the film feeding direction, a developed halogenated film wound around the spool is removed. In a developed silver halide photographic material cartridge in which the tip of the silver photographic material is sent out from the film outlet of the cartridge body, the coefficient of static friction on both sides of the silver halide photographic material after processing is 0.2.
This was achieved by a cartridge for silver halide photographic light-sensitive materials, which is characterized in that it has a value of 5 or less.

The present invention will be described in detail below.

First, the film cartridge used in the present invention will be described. The cartridge used in the present invention is mainly composed of synthetic plastic.

In molding the plastics of the present invention, a plasticizer is mixed with the plastics as necessary. Examples of the plasticizer include trioctyl phosphate, tributyl phosphate, dibutyl phthalate, diethyl sebacate, methyl amyl ketone, nitrobenzene, γ-valerolactone,
Representative examples include di-n-octyl succinate, bromonaphthalene, and butyl palmitate.

Specific examples of plastic materials used in the present invention are listed below, but the invention is not limited thereto.

Specifically, polystyrene, polyethylene, polypropylene, polymonochlorotrifluoroethylene, vinylidene chloride resin, vinyl chloride resin, vinyl chloride-vinyl acetate copolymer resin, acrylonitrile-butadiene-styrene copolymer resin, methyl methacrylic resin, vinyl formal resin, Examples include vinyl butyral resin, polyethylene terephthalate, Teflon, nylon, phenol resin, and melamine resin.

Particularly preferred plastic materials for the present invention are polystyrene, polyethylene, polypropylene, and the like. Furthermore, the cartridge of the present invention may contain various antistatic agents. The antistatic agent is not particularly limited, but carbon black, metal oxide particles, nonionic, anionic, cationic, and betaine surfactants or polymers can be preferably used. These antistatic cartridges are described in JP-A-1-312537 and JP-A-1-312538. Especially, the resistance at 25℃ and 25%RH is 1
0.011Ω or less is preferable.

Usually, cartridges are made of plastic mixed with carbon black or pigments to provide light-blocking properties.

The size of the patrone can remain as it is now, or the current size is 25.
Setting the diameter of the cartridge in m/m to 22 m/m or less, preferably 20 m/m or less, and 14 m/m or more is effective for downsizing the camera.

The volume of the patrone case is 30co? It is preferably below 25ci, more preferably below 20cj. The weight of the plastic used for the patrone and patrone case is 1 g to 25 g, preferably 5 g to 15 g, and the ratio of the internal volume of the patrone case to the plastic used for the patrone and patrone case is 4 to 0.7, preferably 3. ~1.

In the case of a cartridge incorporating the preferable +35 color photosensitive material in the present invention, the total weight of the plastic used for the cartridge and cartridge case is usually 1 g or more and 25 g.
Hereinafter, preferably 5 g or more and 15 g or less. The cartridge of the present invention is not particularly limited in its form.

It is preferable to use the photosensitive material of the present invention in a new camera compatible with a cartridge containing a built-in cartridge.The specific cartridges are shown in FIG. 1, and the internal structure is shown in FIGS. 2 to 4.
The magnetic recording tracks of the film are listed in FIG. Furthermore, the cartridge used in the present invention, which feeds out the film by rotating the spool, will be described. An example of such a cartridge is the one described in Japanese Patent Application No. 1-21862.

FIGS. 6(a) and 6(b) show batrones used in the present invention. Photographic film cartridge 120 has spool 101
, a cartridge main body 103 and a photographic film 102 which is wound into a roll around the spool 101 with one end locked onto the spool 101.

The spool 101 is rotatably attached to the inside of the cassette main body 103 around an axis, and can be rotated from outside of the cassette main body 103. The cartridge main body 103 is provided with a photographic film drawer opening 104 for pulling out the photographic film 102, and a light blocking member 104a is attached to the inner surface of the photographic film drawer opening 104 to keep the inside of the cartridge main body 103 in a light-blocking state. .

In this photographic film cartridge 120, a pair of glue 1108 extends in the circumferential direction along the inner surface of the cartridge main body 103 and has a width of about 15 to 20% of the film width.
are provided at both ends of the film 102 in the width direction.

The rib 108 opens in the direction of the film outlet 104 so that the photographic film 102 can be pulled out from the film outlet 104. Also, film 10
The tip 106 of 2 is aligned with the tip 107 of the photographic film drawer 104.

The rib 108 contacts the outermost surface of the film 102 and presses the rolled film 102 from the outermost surface to maintain the film 102 tightly wound around the spool 101.

The outer diameter of the spool 101 is determined as follows.

As described above, it is difficult to tightly wind the film 102 around the spool 101 while keeping the innermost peripheral surface 102a of the film in contact with the outer periphery of the spool 101. For this reason,
The formation of a gap between the innermost peripheral surface 102a of the film and the spool 101 cannot be avoided. As mentioned above, if the distance between the innermost film surface 102a and the spool 101 is too large, the film 10 as shown in FIG.
2 reversal phenomenon occurs. For this reason, the outer diameter of the spool 101 is set so that when a gap is created between the film innermost circumferential surface 102a and the spool 101, the distance between the two is two or less. In other words, the outer diameter of the spool is a, the inner diameter of the cartridge body is b, the thickness of the rib is t, the thickness of the film is C, and the number of turns of the roll is d, which varies depending on the length of the film.
Then, since b/2=a/2+h+c*d+t, a/2=b/2-t-h-c-d. Since the spacing is h=b/2-a/2-c @d-t, the outer diameter a of the spool when h≦2111I+ is b/2-t-c-d-2≦a/2 becomes.

By setting the interval to two or less, the spool rotation torque can be reduced to 0. If it is set to 8 kgf-an or less, the reversal phenomenon of the photographic film 2 can be prevented.

It is not necessary to provide the ribs 108 along the entire circumferential direction along the inner surface of the cartridge main body 103 (but it is also possible to provide the ribs 108 only on a part of the circumferential direction of the inner surface of the cartridge main body 103. In addition to being provided only at both ends of the film 102 in the width direction, it may be provided over the entire width of the film 102.

The material of the ribs 108 is selected from a material that does not damage the film 102, such as plastic.

In this case, a material having a certain degree of elasticity, such as urethane, may be selected. Spool 1 of film 102
If the thickness of the rib 108 is determined so that the rib 108 made of urethane will shrink when it is loaded into the cartridge main body 103 in a tightly wound state, the shrunken rib 108
Since the outer periphery of the roll of film 102 is pressed by the elastic force of I can do it.

Note that the method of shielding the film outlet from light is arbitrary. A felt-like light-shielding member called a "teremp" may be provided as in the past, or the film drawer opening may be formed to be openable and closable and kept closed except when necessary. Further, the leading end 106 of the film 102 does not necessarily have to be arranged in line with the leading end 107 of the film drawer opening 104, and may be stored inside the cartridge main body 103; desirable.

Furthermore, the cartridge described in Japanese Patent Application No. 1-172594 may also be mentioned. These are of a type in which the film is fed out by rotating the spool while deforming the spool flange and pressing the outermost end surface of the film roll.

In FIG. 201 showing the disassembled state of the photographic film cartridge 1, the photographic film cartridge 201 is
Spool 2 with photographic film 205 wound into a roll
06, a cartridge main body 207 that houses it, and side plates 208 and 209 that rotatably support the spool 206 and close the cartridge main body 207 from the side in a light-tight manner.
It consists of

The spool 206 is integrally molded from plastic, and includes a thinly formed flange 206a that is flexible and a thickly formed flange 206b that is not flexible. The photographic film 205 has its terminal end fixed to the spool 206 between the flanges 206a and 206b, and is wound in a roll shape around the spool 206 so that each end surface is along the inside of the flanges 206a and 206b. The cartridge is completely rolled up into the cartridge main body 207. The cartridge main body 207 has a film entrance/exit 21 to which a light-shielding telescope 211 is attached.
2 is provided.

The end portion 2 of the spool 206 is located in the center of the side plate 208.
06c (see Figure 2) is provided with an opening 208a, and a flange 206 on the inner wall surface.
A protruding portion 208b that presses a portion of a is provided.

The end portion 2 of the spool 206 is located in the center of the side plate 209.
The bearing that rotatably supports 06d is provided with an opening 209a, and in the vicinity of the opening 209a, the inner wall surface of the side plate 209 and the flange 2
Protrusion 209b (second
(see figure) is provided.

No. 202 showing a longitudinal section of the photographic film cartridge 201
In the figure, the inner dimensions of the protrusion 208b and the protrusion 209b are set to be smaller than the outer dimensions of the flanges 206a and 206b, and the protrusion 208b presses and deforms the flange 206a. As a result, the outer end face of the photographic film 205 is more strongly held between the films 206a and 206b than the inner end face. Therefore, if the spool 206 is rotated in the direction of arrow A shown in FIG. 201, the flanges 206a, 206b and the photographic film 205
Due to the frictional engagement with the end surface, the leading end 205a of the photographic film 205 is sent out from the film opening 212 to the outside of the cartridge main body 207.

Also, in the above configuration, the protrusion 208b and the protrusion 2
09b can be made larger than the outer dimensions of the flanges 206a and 206b.

In that case, by pushing the spool 206 in the direction from the flange 206b to the flange 206a with a camera part, the inner dimensions of the flanges 206a and 206b become smaller than the photographic film 205, and the end face of the photographic film 205 can be pressed, allowing the photographic Spool 20 with film 205
It can be sent out to the outside of the cartridge main body 207 by the rotation of 6.

Furthermore, U34834306, U4846418,
The cartridge described in No. 4832.275 is preferably used.

Examples of these are as follows.As shown in FIG. It is held in a rolled state.

Grooves 79a and 79b into which rings 77a and 77b fit are formed inside the cartridge body 78 so as to be inclined with respect to the axial direction of the cartridge body 78.

Therefore, as shown in Figures 10(b) and 1O(c),
Inside the cartridge body 78, the rings 77a and 77b abut against the outer periphery of the opening of the photographic film 76 at an angle inclined with respect to the axis of the spool 75, thereby preventing the photographic film 76 from loosening. Rings 77a and 77b have grooves 79
It is rotatable along the grooves 79a, 79b while sliding in the grooves 79a, 79b.

The photographic film 76 is kept tightly wound around the spool 75 by the rings 77a and 77b, so when the spool 75 is rotated in the opposite direction to the film winding direction, the photographic film 76 is pulled out of the photographic film drawer. (not shown).

Next, the coefficient of static friction on both sides after the development process built into the cartridge having the film feeding function of the present invention is 0.25.
This point will be described below.

In the present invention, the static friction coefficient of 0.25 or less means that the sample is heated to 2.
After conditioning the humidity at 5℃ and 60% RH for 2 hours, HEIDO
This is a value measured using a stainless steel ball of 5 m + φ using an N-10 static friction coefficient measuring machine, and the smaller the value, the better the slipperiness. By reducing the coefficient of static friction, the friction between the emulsion surface of the film and the back surface or the inside surface of the film and the film, as well as the film and the cartridge outlet, can be reduced when the film is fed out from the cartridge by rotating the spool, and the driving torque can be reduced. This can be achieved and the film can be prevented from being damaged.

In the present invention, the static friction coefficient of the film after development is 0.
25 or less, preferably 0.23 or less, more preferably 0.21 or less, particularly preferably 0.20 or less. At this time, it is preferable that both the emulsion surface and the back surface are small, but the smaller the back surface, the better.

In order to make the static friction coefficient of the developed film 0.25 or less, it is sufficient to contain a slipping agent in the emulsion layer and the back layer of the film, and it is particularly preferable to contain a slipping agent in the outermost layer on both sides.

The lubricant can be contained in the coating liquid and then applied, or it can be applied to the film after it has been prepared. There is also a method using a code method, a spin code method, etc.

The slip agent used in the present invention may have a static friction coefficient of 0.25 or less after the development process, and may be incorporated in advance into the film before the development process, or the slip agent may be added during or after the development process. It may also be used by coating. Generally, during development, the slipping agent is often detached from the film surface and the slipping performance is lost, so it is preferable to apply the slipping agent during or after the development processing.

Next, the slip agent used to obtain a static friction coefficient of 0.25 or less according to the present invention will be described.

Sliding agents preferably used in the present invention include those conventionally used in films.
