Abstract

PROBLEM TO BE SOLVED: To reduce offensive noise caused when a photographic film is rewound in a photographic film cartridge. SOLUTION: A vibration suppressing rib 70 brought into contact with the vicinity of the edge of the photographic film 6 rubbing the edge of a lip 17a is formed at the inside wall of an upper case 3. The rib 70 is formed so as to be higher as much as difference H1 than a film pressing rib 50 which is formed at the inside wall of the case 3 near a film gateway 10 and which supports the film 6 from the back surface side and prevents it from being brought into contact with the inside wall of the case 3 and so as to be positioned more inside than the rib 50 in a cartridge main body 5. When the film 6 fed out from the gateway 10 once is rewound, the film 6 is apt to be vibrated because it strongly rubs the edge of the lip 17a. However, since the rib 70 is brought into contact with the film 6, the vibration of the film 6 is suppressed. Thus, the noise caused by the vibration of the film 6 is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 shows the structure of a photographic film cartridge of the present invention.
Has a spool 7 around which a photographic film 6 is wound rotatably housed inside a patrone main body 5 composed of an upper case 3 and a lower case 4 formed from an integrally molded product of resin.
A label 8 is attached to the outer periphery of the cartridge body 5. The upper and lower cases 3, 4 contain 1.5% by weight of silicone and contain additives such as antioxidants. B. High impact polystyrene (HIPS) resin containing (carbon black) was used, and the minimum thickness was 0.9 mm. The spool 7 and a light-shielding door, which will be described later, are also molded using the same resin as the upper and lower cases 3 and 4.

A film entrance 1 for feeding out the photographic film 6 is provided at the front joint of the upper and lower cases 3 and 4.
0 is formed. A light-shielding door 11 for preventing light from entering into the patrone main body 5 is incorporated in the film entrance 10, and a separating unit 6 b formed at the tip of the photographic film 6 is scooped behind the film entrance 10. Are formed integrally with the lower case 3. Keys 13 and 14 are formed at both ends of the light-shielding door 11, respectively. When the key is mounted on the camera, a drive shaft for opening and closing the camera is engaged. The rotation of the opening / closing drive shaft causes the light-shielding door 11 to rotate between a closed position where the film entrance 10 is light-tightly closed and an open position where the film door 10 is opened.

A pair of film-regulating flanges 17, 18 having annular projections, lips 17a, 18a, are attached to the inside of both ends of the spool shaft 16. A data plate 19 is integrally formed at one end of the spool shaft 16, and a rotating member 20 is attached to the other end. A keyhole-shaped hole 21 is formed at each end of the spool shaft 16. When the photographic film cartridge 2 is loaded in the camera, the drive shaft on the camera engages with the hole 21 and the spool 7 rotates. Is done. The rotating member 20 is integrally formed with two ratchet claws 23, a gear 24, and a display plate 25, and these are rotated integrally with the spool shaft 16.

A spool lock 27 is housed inside the cartridge body 5 so as to mesh with the gear 24.
The spool lock 27 is engaged with the gear 24 when the light-shielding door 11 is at the closed position, and locks the rotation of the spool shaft 16 to prevent the careless feeding of the photographic film 6. When the light-shielding door 11 is at the open position, the engagement with the gear 24 is released, and the rotation of the spool shaft 16 becomes free.

The pair of flanges 17 and 18 are injection-molded using a modified nylon PPE in which nylon is blended with PPE (polyphenyl ether), as will be described in detail later. It has become. Round holes 29 and 30 into which the spool shaft 16 is rotatably inserted are provided in the cup-shaped bottom, respectively. The lips 17a and 18a face each other when attached to the spool shaft 16, and enclose the outermost circumferences at both ends in the width direction of the photographic film 6 wound therebetween, forming a roll-shaped photograph. The film 6 is prevented from loosening. Thus, the rotation of the spool 7 can be transmitted to the outermost periphery of the photographic film 6.

The flange 18 is formed with, for example, six holes 32 at a predetermined pitch so as to surround the round hole 30. The ratchet claws 23 of the rotating member 20 are engaged with these holes 32 when the spool shaft 16 rotates in the film feeding direction. The ratchet claw 23 is provided in the hole 32
When the spool shaft 16 rotates in the photo film winding direction, the ratchet claw 23 of the rotating member 20 rides over the hole 32 and the spool shaft 16 rotates. Is not transmitted to the flange 18.

On the inner wall side surfaces of the upper and lower cases 3 and 4, a rib 34 which is a flange restricting means for restricting deformation of the flanges 17 and 18 is formed integrally with the flanges 17 and 18. As shown in FIGS. 1 and 3, three ribs 34 are formed on both inner wall side surfaces of the upper case 3 and the lower case 4 so as to disperse and regulate the outside of the flanges 17 and 18. It has become. The rib 34 is not provided in the vicinity of the film entrance 10 and when the photographic film 6 is fed or unwound from the patrone main body 5, the photographic film 6 pushes the gap between the flange 17 and the flange 18 to expand. 17,1
The vicinity of the film entrance and exit 8 is deformed.

On the outer surface of the data plate 19, a data label 36 on which a bar code indicating various data of the photographic film 6 stored in the cartridge body 5 is radially printed is stuck. The data label 36 passes through the data window 37 formed on the side surface of the upper case 3 and the cartridge 5
And the barcode is read by a device such as a camera.

The rotational position of the spool 7 can be detected by a device such as a camera. When the photo film 6 is rewound into the cartridge body 5,
The photo film cartridge 2 is stopped at an arbitrary position according to the use condition. Thereby, the display plate 2 of the rotating member 20
5 can be seen from any one of the plurality of use status display windows 39 formed on one side surface of the upper and lower cases 3 and 4,
Unused, depending on which window this display board 25 is visible from,
Used, partially used, developed, and the like can be determined.

The leading end 6a of the photographic film 6 has a notch 41 at a side of the end in the width direction which is suppressed by the flange 17.
Are formed. The notch 41 is caught by the flange 17 when the entire photo film 6 is rolled into the cartridge body 5, and prevents the separation portion 6 b, which is a portion on the tip side from the notch 41, from being rolled into the flange 17. belongs to. As a result, the separation portion 6b of the photographic film 6 slightly floats on the outer periphery of the flange 17, and the separation portion 6b and the separation claw 12 are easily brought into contact with each other.
The feeding of the photographic film 6 becomes more reliable. Although not shown, the photographing screen 1 is provided on the notch 41 side.
Two perforations are formed per frame. On the base surface of the photographic film 6, a substantially transparent magnetic recording layer is provided on the entire surface for magnetically recording information.

As shown in FIGS. 1, 3 and 4, on the inner wall of the upper case 3, a pair of film pressing ribs 50, 51 for preventing the exposure range of the photographic film 6 from being damaged are integrally formed. Have been. This extends in the feed direction of the photographic film 6 and supports the outside of the exposure range of the photographic film 6 from the back side on which the photosensitive emulsion is coated. To prevent rubbing. For example, as shown in FIG. 5, the width D ₁ of the photo film 6 is 24 mm, when the exposure range width of 16.7mm, the film pressing rib 50, 5
1 is a distance D of about 18.6 mm so as to be outside the exposure range.
Arranged in _two .

The film presser distance D ₃ apart film widthwise outwardly from the rib 50 and 51, and the position where the back of the cassette shell from the film holding rib 50 and 51, the width of the top portion the pressing film in D ₄ ribs 50 , the difference H ₁ only high vibration suppressing ribs 70 and 71 from 51 is formed on the inner wall of the upper case 3 parallel to the film pressing rib 50, 51. The tops of the vibration suppressing ribs 70, 71 are in contact with the photographic film 6 near a position P where the lips 17a, 18a of the flanges 17, 18 rub against the photographic film 6, and the lips 17a, Vibration of the photographic film 6 caused by strong rubbing between the film 18a and the photographic film 6 is suppressed, and generation of noise due to the vibration is suppressed. In addition, from the center Q of the patrone main body 5 to the position P
The distance L to is set to, for example, about 10 mm.

The photographic film cartridge configured as described above can feed and rewind the photographic film 6 by rotating the spool shaft 7. When feeding and rewinding the photographic film 6, the 17a and 18a of the flanges 17 and 18 and the photographic film 6 are strongly rubbed, and the photographic film 6 tends to vibrate.
Photo film 6 in which vibration suppressing ribs 70 and 71 are near position P
, The vibration of the photographic film 6 is suppressed, and the noise due to this vibration is extremely small.

[0021]

When EXAMPLES changing the height difference H ₁ of the vibration suppressing ribs 70, 71 and the film holding rib 50, 51, or winding state of generation of noise during the return of the photo film 6 how changes The following Table 1 was obtained.
The value of the difference H ₁ is - in the case of (minus), the pressing height film vibration suppressing ribs 70 and 71 ribs 50 and 51
Means lower. The experiment was performed five times each, and the state of noise actually heard by the ear was indicated by the symbols x,
Expressed by △ and △. The symbols x, △, and 〇 mean “unusable for use”, “a slight problem in use, need improvement”, and “no problem in use”. Further, the distance D ₃ 0.8 mm, a width D ₄ was 0.5 mm.

[0022]

[Table 1]

As is apparent from Table 1, when the height of the vibration suppressing ribs 70, 71 is higher than the film holding ribs 50, 51, the generation of noise is small enough to cause no problem in use. Incidentally, the difference H ₁ is in the case of more than 1mm, once delivery of the unwinding of the photo film 6 again after difficult. Further, with respect to Example 2 in Table 1, an experiment was performed on each evaluation of the sending-out force, the drawing-out force, and the repeated taking-in / out of the photographic film 6 as follows.

The evaluation method of the force for feeding the photographic film 6 is as follows. When the weight of 180 g is placed on the tip of the photographic film 6 and the spool 7 is rotated to send the photographic film 6,
The determination was made based on whether or not the leading end of the photographic film 6 could be sent out by a distance of 170 mm in 10 out of 10 times. As a result, they could be sent without any problems.

The evaluation of the resistance when the photographic film 6 was pulled out was such that the maximum value of the resistance when the photographic film 6 was pulled out by rotating the front end of the photographic film 6 between nip rolls was 200 g for 10 of the 10 photographic films. The case where it does not exceed was judged as pass. The measurement result of the resistance was as low as 70 gf at the maximum, and there was no problem at all.

In the evaluation of repeated loading and unloading, the operation of pulling out the photographic film 6 entirely from the patrone main body 5 and then rewinding it 100 times was performed, and when 10 out of 10 photographic films 6 could be loaded and unloaded, the film was passed. Result is,
10 out of 10 photographic films 6 could be taken in and out with 100 operations, and there was no problem at all.

The flanges 17 and 18 were injection-molded using an in-mold gate cut method using a mold as shown in FIG. The fixed-side mold includes a fixed-side cavity 81 for molding the outer shape of the flange 18, a fixed-side insert 82 for forming the ratchet hole 32, and a fixed-side insert 84 for forming the gate 83. The movable-side mold includes a movable-side cavity 86 for molding the outer shape of the flange 18, a sleeve pin 87 for molding a part of the outer shape and projecting a molded product after injection molding, and moving to a fixed side after injection molding. When the product and the sub-runner section 88 are separated, the cut-off pin 89 and an ejector pin 90 that pulls the sub-runner 88 to the movable side and protrudes from the mold are formed.

An air vent 92 that enables ultra-high-speed injection molding is provided at the joint between the fixed side cavity 81 and the movable side cavity 86. This air vent 92
Are provided at least at six locations where weld lines are generated on the outer periphery, and have a width of 0.5 mm to 2.0 mm and a depth of 0.005 m.
It is machined to m to 0.01 mm. This air vent 92
In addition to this, a clearance that does not cause burrs is provided,
It is preferable to actively discharge air. Also, a clearance 93 is provided on the outer periphery of the sleeve pin 87 to the extent that no burrs are generated, and when the molded product is protruded by the sleeve pin 87, air is positively discharged to efficiently release the product. Can be.

The thickness of the flange 18 formed by the injection molding is not necessarily required to be uniform, and the thickness may be partially varied. As shown in FIG. 7, the width of the variation includes the thickness t1 of the spool shaft mounting portion 18b, the stepped portion 18c, the flange body 18d, the lip 18a, and the flange 18e.
t2, t3, t4 and t5 are 0.10 mm to 0.30 m
m, more preferably in the range of 0.13 mm to 0.25 mm. Also, the spool shaft mounting portion 18b, the step portion 18
c, thickness tc1 of corner portions C1, C2, C3, C4 connecting flange body 18d, lip 18a, and flange 18e.
To tc4 may be in the range of 0.05 to 0.15 mm, and may be the same as the thickness t3 of the flange body 18d and uniform. If the thicknesses t1 to t5 of each part are less than 0.1 mm, injection molding becomes difficult. Also, the thickness t1 of each part
If t5 exceeds 0.3 mm, the film drawing resistance becomes extremely large when the flange 18 is incorporated in the photographic film cartridge, and the film cannot be practically used. Further, if the maximum thickness / minimum thickness is k, this k is in the range of 1 ≦ k ≦ 6, preferably 1 ≦ k ≦ 2.7. Also, the thickness tc of each corner C1 to C4
1 to tc4 may be the same as the thicknesses t1 to t5 of each part.

In this embodiment, the thicknesses t1 to t3 and t5 of the spool shaft mounting portion 18b, the stepped portion 18c, the flange body 18d and the flange 18e except for the thickness t4 of the lip 18a are 0.17 mm, and the thickness of the lip 18a is 0.17 mm. The thickness t4 is 0.15
楔 0.19 wedges. The angle formed by the flange 18e formed on the outer periphery of the lip 18a and the inner surface of the flange body 18d is 0 ° to 20 °, and is 0 ° in the present embodiment. By setting this angle to 0 °, the flange 18e becomes parallel to the flange main body 18d, and processing of the injection mold is facilitated.

The angle formed between the lip 18a and the flange body 18d is θ1 = 81 ° to 89 ° on the inside, and the angle θ2 = 90 ° or more, which is about the draft angle, on the outside, and θ1 = 86. 5 ° and θ2 = 90 °. For this reason, the lip 18a and the corner C4 following the lip 18a become slightly thicker than the other portions. However, when the photographic film 6 is fed,
The durability at the time when the side edge of the contact with the corner C4 is excellent.

From the outer surface of the flange body 18d to the corner C
Up to 4 height H ₂ is 1.0 mm to 2.0 mm, preferably a 1.2Mm～1.8Mm. The height H ₂ is 1.0m
If the length is less than m, the outermost peripheral edge of the photo film 6 cannot be gripped, and the winding diameter of the photo film 6 becomes large, which hinders film feeding. Further, when the height H ₂ of the flange 17, 18 is the same, the deflection of the flange 17 is stronger than the flange 18. For this reason, when the photographic film 6 is wound, the photographic film 6 is moved toward the flange 18 in a certain direction, and the meandering of the photographic film 6 is reduced, so that the wrapping of the photographic film 6 is improved. The height H ₂
May be intentionally changed to keep the bias of the photo film 6 constant.

Although the number of the ratchet holes 32 is six, the number of the ratchet pawls 23 of the rotating member 20 is two, so it is sufficient if the number is two or more. May be. Further, the hole 32 may be enlarged in a range up to 1/3 of the flange main body 18d. If the hole 32 exceeds 1/3 of the flange body 18d, the hole 32 comes into contact with the ribs 34 of the upper and lower cases 3 and 4, and the rotation resistance becomes large, so that it cannot be used.

The resin used for molding the flanges 17 and 18 may be a resin having good fluidity in a mold, for example, the above-mentioned nylon-modified PPE, nylon-modified PPE and PS-modified PPE.

The polyolefin-modified PPE is obtained by blending a polyolefin with a PPE. The composition ratio of the polyolefin is, for example, 30 to 70% by weight of the polyolefin,
20 to 70% by weight of E, 0 to 20% by weight of thermoplastic elastomer, preferably 40 to 65% by weight of polyolefin, PPE
25 to 60% by weight, 3 to 15% by weight of a thermoplastic elastomer, particularly preferably 45 to 60% by weight of a polyolefin,
It is desirable to use 30 to 50% by weight of PE and 5 to 13% by weight of thermoplastic elastomer.

As the polyolefin constituting the polyolefin-modified PPE, polypropylene, polyethylene and the like are preferable, and as the thermoplastic elastomer, ethylene propylene rubber, styrene butadiene rubber and the like are preferable.

For example, when it is desired to increase heat resistance together with the nylon-modified PPE and the polyolefin-modified PPE, the ratio of the PPE may be increased. In order to increase the strength, the ratio of nylon or polyolefin may be increased. If it is desired to reduce brittleness, the rubber content should be increased.

In the above-described embodiment, a pair of vibration suppressing ribs is used to more reliably prevent noise. However, only one of the ribs may be used. Further, although the vibration suppressing rib is formed integrally with the inner wall of the upper case, it may be formed by insert molding and made of a resin having better slidability and higher flexibility than the case. Further, instead of the vibration suppressing ribs, telem or non-woven fabric used for 135 type patrone may be welded to the inner wall surface of the upper case. When this telemping is used, dust removal and scratch prevention are also effective, and dust and scratches on the data reading head and the roller section in the camera are reduced.

[0043]

As described above, in the photographic film cartridge of the present invention, a vibration suppressing member for suppressing vibration of the photographic film by coming into contact with at least one edge of the photographic film that rubs against the edge of the lip is formed in the patrone body. Is installed on the inner wall of the patrone body so that it is higher than the film holding ribs that are provided and further inside the patrone body than the film holding ribs, so that the unpleasant noise generated when rewinding the photographic film can be reliably reduced. it can.

Further, since the vibration suppressing member is a rib integrally formed with the inner wall of the cartridge body, it is possible to reduce unpleasant noise generated at the time of rewinding the photographic film extremely easily and at low cost. Also, if the vibration suppressing member is a rib which is insert-molded on the inner wall of the patrone main body with a material having higher flexibility than the patrone main body, it is more effective in preventing the vibration of the photographic film and also preventing the photographic film from being damaged. It is valid. Further, when the vibration suppressing member is formed of an elastic cloth material and is adhered to the inner wall of the patrone main body, it is effective not only for preventing vibration of the photographic film but also for removing dust and scratches in the camera.
