DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film cartridge, and more particularly, to a photographic film cartridge which does not have a film tongue end pulled out of the cartridge, is easily loaded into a camera, and has a reliability of automatic film feeding and mounting. High photographic film cartridge.

[0002]

[Prior art]

As a general photographing film, a roll film conventionally known as JIS 135 patrone has been widely used. At the time of photographing, the user has to perform a troublesome operation of winding the tongue end of the film, which has been pulled out from the cartridge shell, around the take-up spool of the camera. In recent years, even in the case of self-loading cameras which have become widespread in recent years, there are many cases in which a user is required to pull out a film tongue end to a predetermined position and set the film tongue end, and a film cartridge which can be fully automatically loaded and a film cartridge which can be fully loaded. Camera was required.

[0003] US Patent Nos. 4,841,319, 4,834,306, 4,848,693,
Nos. 4,832,275 and 4,846,418 disclose a film cartridge and a camera in which the above problems are improved. This technology is characterized in that a roll-shaped fixed length film is entirely stored in a film cartridge, and after the film is loaded into the camera, the film is unwound from the cartridge by means of engagement between the film cartridge and the camera. As a result, mounting of the film was simplified. However, in the above-described improved technique, there is a problem that a film feeding failure occurs when the spool is rotated by a camera driving system and the film tongue end is fed from the film cassette.

Japanese Patent Application Laid-Open No. 2-115836 discloses a technique for adding a lubricity-imparting agent to a cartridge shell to prevent abrasion at the time of feeding a film. Did not help.

[0005]

[Object of the invention]

Accordingly, an object of the present invention is to provide a film cartridge which is smoothly fed out of a cartridge shell and mounted at a photographing position when a roll film wound and stored in a full length roll shape in a cartridge is loaded into a camera. . More specifically, an object of the present invention is to enhance the reliability of the automatic feeding and mounting function of the film cartridge.

[0006]

Configuration of the Invention

The object of the present invention is to adjust the coefficient of friction between the front and back surfaces of a photographic film having a photographic component layer including a photosensitive silver halide emulsion layer on one surface of a support to 0.1 to 0.35, and to set the photographic film standard size. Means for winding the entire length in a roll shape and storing it inside the cartridge shell, engaging with a camera mechanism and feeding out the photographic film, and means for connecting the outside of the photographic film among the inner surfaces of a tunnel slit formed at the time of feeding the photographic film. This was achieved by an automatic feeding type photographic film cartridge having a slide rail in a contacting part (except when the automatic feeding type photographic film cartridge is loaded in a photosensitive material packaging unit).

That is, as a result of studying in accordance with the object of the present invention, it has been found that poor feeding of the leading end of the film from the film scroll in which the entire length of the film is completely wound into the cartridge shell is caused by the surface of the photographic film and 0.1 ~
Adjusted to 0.35, and furthermore, the automatic feeding mounting type photographic film cartridge which has a slide rail on the part of the inner surface of the tunnel slit formed at the time of feeding the photographic film and which comes into contact with the outside of the photographic film (however, the above automatic feeding mounting type photographic film (Excluding the case where the cartridge is loaded in the photosensitive material packaging unit)), thereby achieving the automatic feeding of the film cartridge and the improvement of the reliability of the mounting function, which are the objects of the present invention. did it. The coefficient of friction between the front and back surfaces of the photographic film is more preferably 0.10 to 0.30, and still more preferably 0.10 to 0.25.

The coefficient of friction in the present invention was determined by the following measuring method. (Measurement method of dynamic friction coefficient between front and back surfaces of photosensitive material) A sample was fixed to a stainless steel fitting with the surface protective layer of the sample placed outside, and a load of 100 g was applied thereto to form a pressure-fixed terminal. Another sample was prepared and fixed on a horizontally movable sample table with the side opposite to the surface protective layer facing up. A pressure fixing terminal having a load cell attached thereon was placed thereon, and the horizontal resistance when the sample table was moved horizontally by 10 μm at a speed of 1 m / min was determined. This was divided by the load of 100 g to obtain the coefficient of friction.

The photographic film according to the present invention is generally provided with a photographic component layer including a photosensitive silver halide emulsion layer on one surface of a support, and a protective layer as an uppermost layer thereof. On the other side, at least one non-photosensitive backing layer is provided.

In the present invention, the photographic component layer side is referred to as the front side of the photographic film, and the back layer side is referred to as the back side. To control the friction coefficient between the front side and the back side, a matting agent and / or a slipping agent are used. And / or means to be present on the back surface is used.

In this method, the front surface and the back surface are not selected, and a coating solution containing a matting agent and a slipping agent is usually applied to be present on the front surface and / or the back surface. When there is no need to distinguish them, they are simply referred to as surface layers.

The structure of the cartridge shell used in the present invention is such that there is no film tongue pulled out, and the entire length of the fixed length is rolled into the cartridge shell in a roll shape. Means for feeding the film.

The configuration of the film cartridge preferably used in the present invention is a double structure in which the cartridge shell of the photographic film cartridge is composed of a sheath tube which is slidably fitted to each other, and a fitting tube which is inserted into the sheath tube. Only one end of each cylinder has a bottom plate with a spool support hole, and a slit parallel to the cylinder axis and an eaves piece in contact with one edge of the slit are provided on each cylinder peripheral surface. Automatically forming a tunnel slit that fits the sheath tube and the fitting insertion tube, makes one surface of the eaves closely contact with each other to make it light-tight, rotates both tubes relatively, separates the one surface of the eaves, and feeds and reloads the photographic film. A feed-out type photographic film cartridge can be used.

FIG. 1 is a sectional view showing an example of such a cartridge shell.

FIG. 1A shows a state in which the two eaves are in close contact with each other to make them light-tight, and FIG. 1B shows a state in which the two eaves are turned to separate the eaves to form a tunnel slit. Show.

In FIG. 1, reference numeral 1 denotes a sheath tube, 2 denotes a fitting insertion tube, and 3 denotes a bottom plate having a spool shaft support hole 4. One bottom plate is provided for each of the two tubes. It is located at both ends of the cartridge shell. The bottom plate may be the same size as the cylinder diameter, or may be protruded from the periphery of the cylinder to form a shape convenient for camera loading or cartridge operation, or processing such as a square, trapezoid, polygon, circle or notch, groove, projection, etc. Etc. can be arbitrarily selected. 11
Numerals 21 and 21 denote a sheath tube and a slit of the fitting tube, respectively. Reference numerals 12 and 22 denote eaves of the sheath tube and the fitting tube, respectively.

Reference numeral 122 denotes a light shielding piece for light entering from the cylindrical tangential direction of the eaves piece close contact surface, and a hook for engaging with the tip 222 of the eaves piece 22 to prevent the opening of the eaves piece. Reference numerals 123 and 223 denote hooks that stably maintain a tunnel slit formed by both eaves pieces when the eaves pieces are opened.

When the sheath tube 1 is relatively turned clockwise from the state shown in FIG. 1A, the sliding rail 121 hidden by the eaves 22 appears. Several slide rails 121 are provided inside the eaves piece 21, and correspondingly, a rail groove 221 indicated by a virtual line in the figure is provided inside the eaves piece 22.

The slide rail 121 and the rail groove reduce the inner surface of the formed tunnel slit 5 in contact with the photographic film, and the outermost slide rail 121 also serves as a light shielding plate for light from the side. Further, the slide rail 121 forms a smooth flat surface with the upper inner surface of the slit 21 in the drawing to eliminate troubles such as catching in film feeding.

Reference numeral 23 denotes a separating claw that guides the leading end of the film that is fed out by sliding along the inner surface of the insertion tube to the formed tunnel slit.

The cartridge shell described above incorporates a scroll,
The photographic film cartridge in the state shown in FIG. 3A is loaded into the camera, and the sheath tube is turned clockwise.
Is disengaged, the hooks 123 and 223 are engaged, the sheath tube and the fitting tube are locked, and the tunnel slit 5 is formed. Next, when the scroll is turned to the left, the photographic film slides on the inner surface of the insertion tube by its own unraveling force, and is easily and reliably fed out of the cartridge with the help of the separating claw 23.

When the photographing is completed, the operation reverse to that described above is performed as shown in FIG.
Is taken out of the camera as a state.

Specifically, the frictional resistance is adjusted by adding fine particles of an inorganic substance such as silica, titanium dioxide, or magnesium oxide, or an organic substance such as polymethyl methacrylate, cellulose acetate propionate, or polystyrene to the surface layer. A method of controlling the coefficient of friction by roughening the surface and reducing the contact area, or adding or attaching a so-called slip agent such as a fatty acid ester compound or an alkyl polysiloxane compound to the surface layer. A method of controlling the coefficient of friction is used.

The method of controlling the coefficient of friction by roughening the surface can prevent not only abrasion fogging but also sticking between photosensitive materials and between photosensitive material and other materials under high temperature conditions. In the present invention, a combination of both is preferred.

The particle size of the fine particles used in the method of controlling the friction coefficient by roughening the surface is preferably 0.5 to 5 μm, and the fine particles of the inorganic compound are silica, and the fine particles of the organic compound are polymethyl methacrylate, polystyrene and methyl. Methacrylate-methacrylic acid copolymers are preferred. The amount used may be selected so that the friction coefficient is 0.35 or less.

[Table 6] The film samples 101 to 107 thus obtained were
Cut to size. Each film was stored in the cartridge shown in FIG. 1 as a fixed-length scroll for 24 photographing frames to prepare a photographic film cartridge.

The full length of the film is completely wound into a cartridge in a roll, and the tongue end is not exposed.

In order to check the reliability of the feeding of the photographic film from these photographic film cartridges, a rotary drive motor is engaged with a spool around which the photographic film is wound, and the photographic film is fed out of the cartridge. Was measured. The results are shown in Table-7.

[0101]

[Table 7] As can be seen from Table 7, the film cartridge of the present invention in which the friction coefficient between the surface layers was 0.35 or less did not cause any trouble in film feeding, and the reliability of the automatic loading and automatic feeding of the film was greatly improved. It became clear that it could be raised.
