Abstract

PURPOSE:To intercept X-rays with respect to a fast film by constituting the cartridge housing the film for photographing of X-ray-interceptive materials. CONSTITUTION:The wall of the cartridge 39 wound with an unused film 26 is constituted of a metallic plate such as an iron plate or a lead plate. Besides, A light sealed movable member such as a winding shaft 22 and a sprocket 23, and a light shielding member 27 itself or its studded material are constituted of mixture with the proper quantity of X-ray intercepting material, such as lead fine powder, and black-colored plastic. The quantity of lead powder to be mixed with this plastic is determined according to the sensitivity of the film housed in the cartridge. Thus, X-ray can be effectively intercepted by the single cartridge without housing it in a bag for X-ray interception since the cartridge itself is constituted of the X-ray-interceptive materials.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an X-ray blocking cartridge capable of blocking X-rays.

BACKGROUND OF THE INVENTION It is generally known that ordinary photographic films suffer from blurring when exposed to X-rays.

By the way, in the past, baggage has been subjected to X-ray inspection at international airports, etc., and travelers must be careful not to expose photographic film in their baggage to X-rays during this X-ray inspection. be.

However, as the number of overseas travelers has increased rapidly in recent years, few travelers have been exposed to X-ray irradiation, and their photographic film has often been exposed to xtQ.

Therefore, recently, X-ray blocking bags have been commercially available, and by storing the cartridge in this bag, fogging of the photographic film can be effectively prevented.

Problems to be Solved by the Invention However, not all travelers have yet used the above-mentioned bags, and photography film has often been exposed to X-rays.

In addition, in recent years, high-sensitivity films have become popular and are useful to travelers, but many of the bags mentioned above do not have the ability to block X-rays from such high-sensitivity films. However, even though the film was placed in the bag mentioned above, fogging sometimes occurred on the film.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an X-ray blocking cartridge that can effectively block X-rays in order to solve the above-mentioned problems.

In order to achieve the above object, the cartridge itself is configured to be able to block X-rays. That is, in a cartridge for storing photographic film, the cartridge is designed to be able to block X-rays. It is constructed from a material that can interrupt wires.

In the above structure, the wall of the cartridge may be made of a material containing an X-ray blocking material.

In the above structure, the film winding shaft whose one end is exposed to the outside of the cartridge and the light shielding member at the film entrance/exit of the cartridge may each be made of a light shielding and X-ray shielding material.

Effects and Effects of the Invention According to the above configuration, since the cartridge itself that stores the film is made of a material capable of blocking X-rays, the cartridge alone can block X-rays without storing the cartridge in an X-ray blocking bag. This can be done effectively and the photographic film inside the cartridge can be prevented from being exposed to X-rays. Also, unlike such bags, each cartridge can be provided with an X-ray blocking function suited to the sensitivity of the film stored therein. In other words, conventionally, in order to ensure film X-ray blocking, travelers must compare the sensitivity of the film and the X-ray blocking function of the X-ray blocking bag, and choose a bag that is suitable for the sensitivity of the film. had to choose. However, according to the present invention, the X-ray blocking function can be adjusted for each cartridge according to the sensitivity of the film inside it, so there is no need for travelers to make comparisons as in the past. . Therefore, the traveler can protect the photographic film in his/her baggage from irradiation with X-rays without paying any special attention to it.

Embodiments of the present invention will be described in detail below with reference to Figures 1-19 and 22.

The film cartridge 39 according to this embodiment has the first.
As shown in Figure 2, the film 26 in an unused state

The film 26 is sent out frame by frame from the film 14 cartridge 39 and wound onto the sprocket 41. On the other hand, after photographing is completed, the film 26 in the film chamber is automatically wound onto the winding shaft 22 in the film cartridge 39 by driving the film winding drive member.

FIG. 4.5 shows a camera that embodies the camera shown in FIG. This figure shows a state in which a film cartridge 39 is about to be stored in the cartridge storage chamber 40 through the film cartridge entrance/exit port 43 opened on the bottom surface of the camera body 31. Further, FIG. 6 shows a state in which a film cartridge 39 is housed. At the upper end of the cartridge storage chamber 40 is a first fork serving as a film winding drive member for the camera body 31! 30 and a second fork 131 as a film feeding drive member of the camera body 31 respectively protrude downward, and the first fork 130 engages the first engaging portion 22a of the film cartridge 39 and the second fork 131 as a film feeding drive member of the camera body 31. The forks +31 are respectively disengaged from the second engaging portions 23a of the film cartridge 39.

In addition, in FIG. 4.6, shi indicates a lens.

Figure 7(a) shows the above first fork! 30 and the second fork 131, respectively, are shown. As shown in FIG. 4 and FIG. 7(a), a motor 101 is provided in the spool 41, which operates during the feeding operation, winding operation, and winding operation of the film 26, respectively. The motor! 01 rotates the gear 103 and gear 107 fixed to the camera body 31 via the reduction gear 102.

The gear +03 includes a carrier plate 105 that is rotatably fixed at one end to the center axis P1 and rotatably supports the planetary gear 104 at the other end, and the gear +03 and the planetary gear! 04 and interlock with each other. The planetary gear 104 is disposed close to the gear 10G that rotates the subwheel 41. Therefore, when the gear 103 rotates clockwise on the medium scale in FIG. 7(a),
The carrier plate +05 and the planetary gear 104 both rotate clockwise in the middle of FIG. Conversely, the gear 103 shown in FIG.
a) When rotated clockwise, the carrier plate 105
and the planetary gear 104 is a seventh gear centered on the axis P1.
The planetary gear +04 is rotated clockwise in FIG.

Further, the gear 107 includes a carrier plate 108 that has one end rotatably fixed to the center axis P2 and a carrier plate 108 that rotatably supports the planet gear 109 around the center axis P4 at the other end. gear! 09 are interlocked with each other. The planetary gear +09 is arranged close to the gear 110 that rotates the sprocket 23 and the gear Ill that rotates the film take-up shaft 22.

If it is determined that the timer set in step 331 has ended, that is, if it is determined that some abnormality has occurred and the film 26 has not been wound by one frame, the motor lot is stopped in step 5334. , then in step 5335 the display device D
After displaying a warning on S, the hoisting operation is ended in step 5329.

Incidentally, after a warning is displayed on the display device DS in step 5335, a winding operation to be described later may be performed.

Further, in the step 5311, if it is determined that the final frame flag is set to indicate that the remaining frames are the final frames and that the photographing of the final frame of the film 26 has been completed, the film is unwound. To start the operation, reverse rotation of the motor 101 is started in step 5312, and then a timer is set in step 5313. In step 5312, the motor! When 01 is reversed, its rotation is transmitted to the gear 103 via the reduction gear +02, and the gear +03 rotates its axis P1.
It rotates clockwise in FIG. 7 around . the result,
The planetary gear 104 rotates counterclockwise in FIG. 7 about its axis P, and the carrier plate 105 rotates clockwise about the central axis P of the gear 103. leaves the gear 106. Similarly, the rotation of the motor 101 is also transmitted to the gear 107 via the reduction gear 102,
7 rotates clockwise in FIG. 7 about its axis P. As a result, the planetary gear 109 rotates counterclockwise in FIG. 7 about its axis P4, and the biped carrier plate 108 rotates clockwise about the central axis P of the gear 107. The planetary gear 109 is separated from the gear 110 and meshes with the gear II+ which is disposed adjacent to the lower part in FIG. Therefore, gear 21
rotates clockwise in FIG. 7, and this rotation is transmitted to the film winding shaft 22, which in turn rotates clockwise in FIG. Then, the film 26 is wound onto the film winding shaft 22. Furthermore, since the engaging pawl of the sprocket 23 engages with the perforation 26a of the film 26, the film 26 is engaged with the perforation 26a of the film 26.
6 is wound up on the film winding shaft 22, it freely rotates clockwise in FIG.

Then, the sprocket rotation amount detection circuit RD outputs a number of pulses corresponding to the rotation amount of the sprocket 23, and the number of pulses is counted in step S3!4.

Next, in step 5315, the above step 531
Cebu in 3! - Determine whether or not the timer has ended, and if it is determined that the timer has not ended, in step 531 (3), the number of pulses counted in step 5314 It is determined whether a predetermined number C corresponding to the amount of the film 26 wound onto the spool 4 has been reached.

In step 5316, the number of pulses is set to a predetermined number C.
If it is determined that the value has not been reached, step 531
Return to 4.

If it is determined in step 931B that the number of pulses has reached the predetermined number C and is greater than the predetermined number C, then the entire film 26 is rewound into the film cartridge 39, and the film 26 is rewound into the film cartridge 39. If it is determined that the wire has come off the sprocket 41 and is wound up on the take-up shaft 22, the switch S is turned off in step 5317.
3 is turned on, and then turn the take-up shaft 22 and the first
When the fork 130 is located at the same predetermined rotational position as in the initial state, the motor 101 is stopped in step 9318. If switch S3 is not turned on, wait until switch S is turned on. In step 8316, after the number of pulses reaches the predetermined number C, the motor 101 is further reversed for a predetermined time so that the number of pulses becomes greater than the predetermined number. The engagement between the film 26 and the engagement pawl of the sprocket 23 is surely released, and the film 26 up to the leading end is wound onto the film winding shaft 22.

When the motor 101 is stopped in step 5318 above,
Next, in steps 5319 and 5320, the motor 101 is reversed until the switch S4 is turned on, and when the switch S4 is turned on, the reverse rotation of the motor 101 is stopped in step S32■. That is, this allows the sprocket 23 and the second fork +31 to be positioned at the same predetermined rotational position as in the initial state. Next, in step 5322, the display device 1) indicates that the winding of the film 26 is completed.
After displaying S, the film winding operation is ended in step 5329. At this time, the film 26 has returned to its initial position.

Note that in step 5316, when the number of pulses slightly smaller than the number of pulses C corresponding to the wound film 26 (the number of pulses corresponding to within the film winding amount of one rotation of the winding shaft 22) is counted, step 5317 is performed. You may also ask them to proceed.

In addition, in the step 5315, the step 5
If it is determined that the timer set in step 313 has ended, that is, if it is determined that due to some abnormality, the film 26 is not completely wound onto the film winding shaft 22 even after a predetermined period of time has elapsed. steps 8323-532 similar to steps 8317-5321.
Do step 7. That is, in step 5323 switch S is activated.

is turned on, and when switch S3 is turned on, the winding shaft 22 and the first fork! are turned on in step 5324. When the motor 30 is located at the same predetermined rotational position as in the initial state, the motor 10I is stopped. Next, in steps 5325 and 5326, the motor 101 is reversed until the switch S4 is turned on. Then, when the switch S4 is turned on, the sprocket 23 and the second fork 13 are turned on in step 5327.
When + is located at the same predetermined rotational position as in the initial state, the motor 101 stops rotating in reverse. Next, in step 5328, a warning is displayed on the display device DS, and then in step 5329, the winding operation is ended.

By the way, when the film cartridge 39 is taken out from the film cartridge storage chamber 40, that is, when the switches S and 2 are turned off, or when the film cartridge 39 is not loaded (switch SQ is turned off), the iLD is opened. (Switch S is off)
Then, an interrupt INT3 as shown in FIG. 12 is executed. Operation steps 8402 to 5407 at this time are the ninth
This step is similar to steps 5I04 to 5109 in the figure, and the first fork 130 and the 274th fork 13+ are moved to the initial rotation position, respectively.

Next, a mechanism for holding the film 26 at a predetermined position relative to the film car 1-ridge 39 in a two-legged camera will be explained.

13 and 14 are a plan view and a cross-sectional side view showing a sprocket locking mechanism inside the film cartridge 39, respectively. The sprocket 23 is rotatably held within the film cartridge 39,
Its sprocket teeth 23b engage perforations 26a in film 26. The second retaining portion 23a at the upper end of the sprocket 23 engages with the second fork 131 of the camera body 31 when the film cartridge 39 is loaded into the film cartridge storage chamber 40 of the camera body 31. The sprocket 23 has a notch 23c in the flange fixed to the middle part of its shaft, and the locking member 2
It engages with the protrusion 29b of No.9. The locking member 29 has a small-diameter pushing portion 29a serving as an engaging portion for releasing the lock at one end thereof, which is fitted into the small hole 2Ic of the case 21 of the film cartridge 39 so as to be movable in the axial direction. A guide tube portion 21h is formed on the exposed inner surface of the case 21 in which the small hole 21c is formed, and guides the movement of the proximal end portion of the push portion 29a of the locking member 29 in the axial direction. A spring 30 is stretched between the lower end of the lock member and the case 2I, and as shown in FIG.
9 is constantly urged upward, so that the proximal end of the pushing portion 29a of the bipedal locking member 29 comes into contact with the upper inner wall of the case 21 of the film cartridge 39. With the locking member 29 in contact with the inner wall of the case due to the spring 30, even if an attempt is made to rotate the sprocket 23, the locking mechanism will work because the locking member 29 locks the sprocket 23.
Sprocket 23 does not rotate. The purpose of this locking mechanism is to prevent the user from accidentally rotating the sprocket 23 and causing the leading edge of the film 26 in the film cartridge 39 to come out of the film cartridge 39, or conversely to prevent it from being rolled into the film cartridge 39. It is something to do.

Next, the operation will be explained. As shown in FIG. 4, the use stand loads the film cartridge 39 into the film cartridge storage chamber 40 of the camera body 31.

At this time, the release pin 150 as a lock release member provided in the film cartridge storage chamber 40 enters the small hole 21c of the case 21 of the film cartridge 39,
It comes into contact with the push part 29a of the locking member 29. As it is further loaded, the pushing part 29a of the locking member 29 will move as shown in FIG.
Pushed downward, the notch 23c of the sprocket 23 and the protrusion 29b of the locking member 29 are disengaged, and the sprocket 23 becomes rotatable. At this time, sprocket 2
3 is also engaged with the second fork +31, but when the lock is completely released, the engagement between the second fork 131 and the sprocket 23 has already been completed. (!: The pushing part 29a of the locking member 29 is arranged on the camera body 31.
As the fork +31 rotates, the unlocked sprocket 23 rotates, and the film 26 is fed out.

Note that when the sprocket 23 is locked by the locking member 29, the second fork 1 on the camera body side
The phase of the second engaging portion 23a of the sprocket 23 that engages with the sprocket 31 is always set to a predetermined phase. If the second fork 131 on the camera body side is also set in phase to match the phase of this engaging portion 23a, when the film cartridge 39 is loaded into the camera body 31, the second fork +31 and the engaging portion 23a will smoothly connect. engaged, sprocket 23
The amount of rotation of the gear 110 that rotates the film and the amount of film feeding can be made to correspond one-to-one. When rewinding the film, if the motor 101 is stopped after the film has been rewound by the same amount as the amount m that has been fed out, the second fork +
It is possible to keep the 31 phases in the same state as before sending them out.

Moreover, it is also possible to employ not only the above-mentioned mechanism but also a mechanism as shown in FIG. 11. That is, in the embodiment shown in FIG. 1t, the sprocket 23 can be unlocked from either the top or bottom of the cartridge 39. This is to increase the degree of freedom in camera design.

The lock member 29-1 has a protrusion 29b for stopping the rotation of the sprocket 23-1 in the same manner as described above, and above and below the protrusion 29b, there are small holes 21c and 21e in the case 21 of the cartridge 39 and an inner wall around the hole. Guide cylinder part 21f, 2
Push portions 29a, 2 each fit movably in the axial direction to 1g.
9a, and either of the push portions 29a, 29a is pushed by the release pin I50 of the camera. Then, the two springs 30-1 and 30-2 are stretched between the inner wall of the case 21 and the locking part 29c of the locking member 29-1, and the locking part 129-1 is pushed from either side, up or down. Even if the sprocket 23 is unlocked, the two springs 30
-1.30-2 to restore the original state. Note that in this embodiment, the sprocket 23-1 is the second engaging portion 23a.

23a are provided at two locations below the case 21 and are exposed through the holes 21b and 21d through which the case 21 is passed. This also leads to greater freedom in camera design.

In this case, the phases of the second engaging portions 23a, 23a are set to a predetermined phase. In addition, the winding shaft 22
The first fork on the camera body side may also be locked to the same mallet as the sprocket 23-1, by adjusting the phase of the first engaging portion 22a of the winding shaft 22 to a predetermined position. 30, the film cartridge 39 can be inserted even more easily.

Furthermore, a mechanism other than the above may be employed. In other words, the film feeding mechanism of a film cartridge equipped with a film feeding mechanism is locked when the cartridge is alone, but is unlocked when it is housed in the camera body.1. In the embodiment E, the feed lock is released when the cartridge 39 is loaded into the camera body 31 with the lids t and D removed, so the lid LD is opened and the film cartridge 39 is loaded. If left in this condition, light may enter the film cartridge 39 from around the lock release mechanism, or the film 26 may be damaged by the sprocket 23 inside the cartridge due to the winding elasticity of the film 26.
There is a risk that it may come off. Therefore, in the following modified example, a method of releasing the film 26 feed lock more safely with a different configuration will be presented. Furthermore, the above-mentioned problems and their solutions should be taken into consideration not only when loading the cartridge 39 into the camera body 31 but also when taking out the photographed cartridge 39 from the camera body 31.

FIG. 16 shows the first modification, in which the cartridge 39
A release bin 50 is provided on the inner surface of the lid LD, which houses the cartridge storage chamber 40 and seals the cartridge storage chamber 40 in a light-tight manner, as a release member for releasing the delivery lock mechanism inside the cartridge. By closing the iLD, the release bottle 50 is released from the cartridge 39 [pushing portion 29a of the knocking member 29].
The feed lock is released by engaging with and pressing this.

In the case of this modification, compared to the release method presented in the above embodiment, the delivery lock mechanism is not released just by placing the cartridge 39 in the cartridge storage chamber 40 of the camera body 31, but is released just before the HLD is closed. With this configuration, the chances of the above problem occurring can be reduced. Incidentally, the first modified example is a first one that engages with the cartridge 39 and drives the film. second fork 130,
131 together with the cartridge storage chamber 40 of the camera body 31.
The release bin 50 is provided on the upper wall side of the first. 2nd fork 1
30 and 131 are provided on the lid LD on the opposite side, so when loading the cartridge 39 into the camera body 31, the cartridge 39 is
This can prevent the inconvenience of floating.

Further, FIG. 17 shows a second modification, in which the camera body 31
There is a support 53 in the upper wall of the film cartridge storage chamber 40 inside.
The swing arm 52 is swingably supported by the swing arm 52, and a release bin 5 as a lock release member that can protrude into the storage chamber 10 is provided on the lower end surface of one end of the swing arm 52.
2a, and a bushing rod 51 is provided at the other end of the housing chamber 40 so as to be movable in the vertical direction in FIG. 17 within the side wall of the storage chamber 40. The lower end of this bushing rod 51 is
It is possible to touch one end of the Therefore, when the lid LD is closed, the bushing rod 51 is moved in the axial direction by the lid LD, and the swing arm 52 is swung around the shaft 53 to cause the release bin 52a to protrude into the storage chamber 40. 52a presses the pushing part 29a of the locking member 29 of the cartridge 39, thereby releasing the delivery locking mechanism in the cartridge 39.

In this case, not only the effect of the first modification but also the MLD
Since there is no need for bottles or the like, there is also the effect that attachment and detachment of the cartridge 39 will not be hindered.

Furthermore, FIG. 18 shows a third modification, in which the camera body 3
An arm 58 is provided within the 1-wall of the film cartridge storage chamber 40 in the storage chamber 40, one end of which is swingably supported by a shaft 57, and an engagement member that can protrude into the storage chamber 40 at the lower end surface of the other end of the arm 58. A release bottle 58a is formed as a release member. On the other hand, an upper end of a rank lever 55 is pivotally attached to one end of the arm 58 by the shaft 57 so as to be able to swing within the side wall of the storage chamber 40 . What is the lower end of this crank lever 55? Slidable lock member 5 provided in iLD
It is possible to touch one end of 4. The locking member 54 has operating portions 54a exposed to the outside at and p on the lower surface of its base end, and Z (two upper and lower planes parallel to the inner surface and both vehicle surfaces) on two surfaces of the base end. A cam surface 54c is formed with an inclined surface connecting the lid LD, and the upper end of the cam surface is provided with a release pin 59 as a lock release member that can protrude into the storage chamber 40.Therefore, the lid LD is closed and the locking member 54 is slid to the right in FIG. By pressing the pushing part 29a of the locking member 29, the delivery lock mechanism in the cartridge 39 is released.At the same time, in the above structure, when the locking member 54 is slid, the crank lever 55 and arm 58 respectively swing to release the release pin 5.
8a protrudes into the storage chamber 40, and the locking mechanism is released by the release pin 58a.

In this case, the release pin 59 is connected to the cam 54 of the locking member 54.
c, the release pin 58a is configured to push the pushing part 29a of the locking member 29 of the cartridge 39 by the arm 58 and crank lever 55, but it goes without saying that originally only one side of the release pin 58a is pressed. Also, the first
In Figure 8, 56 is a closing completion detection switch Ss that is turned on at the final stroke of the operating stroke of the crank lever 55;
Although it is configured to prevent the film advance from starting in conjunction with a cartridge detection switch S12 (not shown), if the movement of the lock member 54 is configured to be detected, the release pin 5
9 as well as a closing completion signal related to the movement of the release pin 58a.

In the case of this third modification, when the closing operation of the MLD is completed and secured by the lock member 54, the cartridge storage chamber 40 is made completely light-tight, and then either the release pin 59 or 58a is opened. Since the delivery lock is released, the fill 1226 is not exposed to external light.

In addition, since the switch Ss is also configured to operate in conjunction with the release of the feed lock, the film transfer process can be started immediately when the lock is released, and the film 2
The above-mentioned problems such as the winding elasticity of G do not occur. Furthermore, in the third modification, when the cartridge 39 is taken out after the camera operation is completed, the release pin 59 or 58a is released in conjunction with the release operation of the lock member 54, and the lock member 29 of the cartridge 39 is locked. Since the state is restored, by the time the MLD is opened, the cartridge 39 delivery mechanism has already been relocked, and the above-mentioned problem is prevented from occurring.

Furthermore, FIG. 19 shows a fourth modification, in which the storage chamber 4
An arm 67 whose one end is swingably supported by a shaft 68 is provided in the earthen wall of 0, and a release pin 67 as a lock release member that can protrude into the storage chamber 40 is provided on the lower surface of the other end of the arm 67.
Equipped with a. A locking member 64 is slidably provided in the lid LD, and the locking member 64 has the lid 1. An operating portion 64a is formed which is exposed to the outside of the camera D, and one end thereof comes into contact with a movable contact piece 65 inside the camera body 3I when it is slid, and the movable contact piece 65 is brought into contact with a fixed contact piece 66. Make it. A slidable slide lever 62 is provided at the base end of the lid LD, and the lower end of the lever 61 is provided in the side wall of the storage chamber 40 so as to be swingable by a shaft 61. It can be brought into contact with one end. Further, a force 11 and 62b is formed on the upper surface of the slide lever 62, which is made up of two planes parallel to the inner surface of the lid, upper and lower, and an inclined surface connecting both planes, and the upper end is placed on the cam surface in the storage chamber. A release pin 63 is provided as a lock release member that can protrude into 40. In the two-leg configuration, when the lid Ll) is closed and the knock member 64 is slid by the operation section 64a, the cartridge 39 is unlocked in the initial operation of the film feed operation by a motor (not shown). are doing.

In this case, since the detailed structure inside the camera body is based on the above-mentioned embodiment presented earlier, only the parts related to film advance will be explained in detail.

In the case of this fourth modification, the MLD is closed and the locking member 6

07 rotates counterclockwise, and the lever 108 moves in the direction of the arrow (
(counterclockwise). In this case, Philno
Gear I connected to the second fork 131 that drives the delivery mechanism
Since gear 107/gear 1.9 is still in the disengaged state, lever 108 moves in the direction of the arrow above before the feeding mechanism is driven.

In conjunction with the movement of the lever 108 in the direction of the arrow, the slide lever 62 moves to the right in the figure by swinging in the counterclockwise direction about the shaft 61 of the first collar 60, and the cam G2
By moving the release pin 63 into the cartridge 39 by b, the knock of the film cartridge 39 delivery mechanism is released. Alternatively, in conjunction with the movement of the lever 108, the arm 67 moves 11G counterclockwise about the shaft 68, and the release pin 6 as a latch release + 1s material.
By moving 7a into the cartridge 39, the delivery lock in the cartridge 39 is released.

With this configuration, the feed lock can be released immediately before the film feed mechanism starts driving, so the above problem does not occur. In addition, although the handling at the time of rewinding is not specified in FIG. 19, it may be re-locked after rewinding is completed, and the user can slide the locking member 64 to the left to unlock the JLD. You may want to re-lock it when necessary.

According to the structure of the above-described embodiment of the present invention, since the cartridge itself that houses the photographic film 26 is made of a material capable of blocking X-rays, the cartridge 39 can be stored in an X-ray-shielding bag without having to store it in an X-ray shielding bag. The cartridge itself can effectively block X-rays, and the photographic film 26 inside the cartridge can be prevented from being exposed to X-rays. Therefore, the traveler can protect the photographic film in his/her baggage from irradiation with X-rays without paying any special attention to it.

Note that the present invention is not limited to the above embodiments,
It can be implemented in various other ways. For example, the cartridge 39 may be made of a plastic resin containing lead powder, the cartridge itself may be made of lead, or the cartridge 39 may be made of lead bonded to other metals such as iron. may be formed. In this case, the thickness of the lead may be determined depending on the sensitivity of the film 26 housed in the cartridge.

Further, FIG. 22 shows the operation of a camera according to another example to which the embodiment of the present invention is applied. In this example, step 5I3
20 and 51326 are holes, and 111j No. 111'
Same as Figure 3 (, η. Step 51320, S+32
Step 6 differs from step 5320°832G in the previous embodiment in that, in the previous embodiment, it was detected that the switch S was turned on, whereas in this example, it was detected that the switch S was turned on. It is a point.

As shown in FIG. 7(b), the pattern P'1'lc constituting the switch S is arranged to have a phase difference by a predetermined angle θ (approximately 90 degrees in the figure) from the pattern PTIb constituting the switch S4. ing. Therefore, step S+320. of FIG. S321 or step 51326.5
327, when the motor 101 is stopped when the switch S5 is turned on, the film take-up shaft 22 of the film cartridge luger 39 is in the state before loading into the camera (before use). This means that it is stopped at a phase shifted by θ from the initial state). On the other hand, the first fork 1 of the camera
31, when the film cartridge 39 is taken out from the film cartridge storage chamber 40, the initial rotation (return to the apparatus) is performed by executing the interrupt INT3 shown in FIG. 12, as in the previous embodiment.

Therefore, when I tried to load the film cartridge into the camera again after taking a photo, the film take-up shaft 22 and the first fork! Because the phase of 31 is 0 out of 0, smooth loading is not possible, and the first fork 13I is a coil spring! It cannot be loaded unless it is pushed in against 32. This allows the user to know that an attempt is made to reuse film that has already been shot by mistake. still,
If the 17th column is prevented from retreating, it will be impossible to accidentally reuse it.
