Description

  The present invention particularly relates to a photosensitive recording medium cartridge that accommodates a photosensitive recording medium, and more particularly, affects the light shielding performance and dustproof performance of a photosensitive recording medium cartridge that accommodates a hologram recording medium as a photosensitive recording medium. The present invention relates to an improvement for facilitating management on the distribution or library without giving.

A hologram recording medium for recording data by hologram has been invented (see, for example, Patent Document 1).
The above-mentioned hologram recording medium is a photosensitive recording medium in which a hologram recording layer made of a photosensitive material is layered on a disc-shaped support, and has been widely used by recording data in a multilayer manner as interference fringes of laser light. Thus, a larger data recording capacity can be obtained than a DVD that is a recording medium.

  By the way, the hologram recording medium has an adverse effect on the data recording performance, for example, when the hologram recording layer is exposed to light during storage or dust adheres to the hologram recording layer. The handling in the form accommodated in the cartridge which has a function becomes indispensable. Of course, in order to avoid inadvertent exposure and the like even when set in a data read / write device that reads / writes data to / from the hologram recording layer, it is indispensable that the device can be loaded in the form of being accommodated in a cartridge. Become.

  Therefore, as such a cartridge, a cartridge main body that rotatably accommodates the hologram recording medium so as to be sandwiched between the upper shell and the lower shell, and a part of the hologram recording medium provided in the cartridge main body is exposed to the outside. Various types of configurations including an opening to be opened and a shutter for opening and closing the opening have been proposed (see, for example, Patent Document 2).

JP 2004-029476 A JP 2003-317422 A

By the way, the hologram recording medium is significantly superior to a recording medium that has been widely used in terms of data recording capacity and the like.
Product management in the distribution field at that time, data location management when data is stored in a large number of hologram recording media to form a library, search and extraction of desired recording media from a large number of libraries, etc. In order to facilitate this, it is indispensable to provide the cartridge with identification information necessary for management.

However, in the conventional cartridge, there is no description describing considerations for such product management and data location management.
Therefore, the application of bar code management technology, which is currently popular in the distribution field, was examined, but the following problems were pointed out.

The first problem is that the position where a barcode can be applied is limited, and the degree of freedom in designing a package such as a packaging container is reduced.
In other words, the mounting of the barcode requires a considerably large area, but the cartridge for storing the hologram recording medium is a thin rectangular box having a thickness of several millimeters, and other than the front or back side of the box, a par The space to give the code cannot be secured. Therefore, the position where the parcode is applied is limited to the front surface or the back surface of the cartridge, which causes a problem that the degree of freedom in designing a package such as a packaging container is lowered.

Second, there is a problem that workability at the time of reading the identification information is poor.
As described above, when barcodes are applied to the front or back surface of the cartridge box, if a large number of cartridges are aligned and accommodated so that the front and back surfaces of each other overlap, the applied barcodes are hidden by adjacent cartridges, and the accommodated state Then, the barcode cannot be read.
Therefore, for example, when it is necessary to read the identification information of each cartridge in a state where a large number of cartridges are housed in a library or a product display shelf, the cartridges are taken out one by one. Therefore, it has to be applied to a bar code reader, resulting in a problem of poor workability when reading identification information.

Third, the provision of identification information using a barcode is a problem that the reliability of information maintenance is poor when reading of information is frequently repeated.
That is, the barcode is given by, for example, sticking a sticker on which the barcode is printed on the front or back surface of the cartridge or a predetermined position of the cartridge packaging container. The identification information assigned to each cartridge may be read out by a library, etc. In applications that are frequently repeated, there is a problem that the reliability of information maintenance is poor.

  Fourthly, as described above, when reading the barcode, it is necessary to take out the cartridge one by one, and the number of times of contact with the cartridge increases. Or the shutter mounted on the cartridge moves to increase the risk of adversely affecting the light shielding performance and dustproof performance of the cartridge.

  Accordingly, an object of the present invention is to solve the above-mentioned problems, and the degree of freedom in packaging design such as a packaging container is not reduced due to the provision of identification information, and workability at the time of reading identification information is also improved. In addition, even in applications where the reading of identification information is frequently repeated, there is no risk of losing the identification information in the middle, ensuring high reliability in maintaining the identification information. It is an object of the present invention to provide a photosensitive recording medium cartridge that can be easily distributed and managed on a library without being soiled or deteriorating the light shielding performance and dustproof performance of the cartridge.

The above object of the present invention is achieved by the following configurations.
(1) A cartridge main body that rotatably accommodates a disc-shaped photosensitive recording medium so as to be sandwiched between an upper shell and a lower shell, an opening that is provided in the cartridge main body and exposes the photosensitive recording medium to the outside, A photosensitive recording medium cartridge comprising a shutter attached to the cartridge body so as to be movable between a closing position for closing the opening and an opening position for opening the opening, wherein the photosensitive recording medium is An RFID tag is mounted in the cartridge body at the outer peripheral portion of the disk housing portion of the cartridge body so that the data communication surface is inclined with respect to the insertion direction of the photosensitive recording medium cartridge into the apparatus in the cartridge body. A photosensitive recording medium cartridge.
(2) The photosensitive recording according to (1) above, wherein an inclination angle of a data communication surface of the RFID tag is set to 45 ° with respect to an insertion direction of the photosensitive recording medium cartridge into the apparatus. Media cartridge.
(3) A cartridge body that rotatably accommodates a disc-shaped photosensitive recording medium so as to be sandwiched between the upper shell and the lower shell, and an opening that is provided in the cartridge body and exposes the photosensitive recording medium to the outside. A recording / reproducing apparatus that performs recording / reproduction on a photosensitive recording medium cartridge having a shutter attached to the cartridge body so as to be movable between a closed position for closing the opening and an open position for opening the opening. The RFID tag is mounted in the cartridge body at an outer peripheral portion of the disk housing portion in a posture in which the data communication surface is inclined with respect to the insertion direction of the photosensitive recording medium cartridge into the apparatus in the cartridge body. A recording / reproducing apparatus comprising an information exchanging unit that reads and writes information from and to the device.
(4) A cartridge main body that rotatably accommodates a disc-shaped photosensitive recording medium so as to be sandwiched between the upper shell and the lower shell, and an opening that is provided in the cartridge main body and exposes the photosensitive recording medium to the outside; This is a recording / reproducing method for performing recording / reproduction on a photosensitive recording medium cartridge having a shutter attached to the cartridge body so as to be movable between a closed position where the opening is closed and an open position where the opening is opened. The RFID tag is mounted in the cartridge body at an outer peripheral portion of the disk housing portion in a posture in which the data communication surface is inclined with respect to the insertion direction of the photosensitive recording medium cartridge into the apparatus in the cartridge body. A recording / reproducing method characterized in that information is read from and written to.
(5) A cartridge main body that rotatably accommodates a disc-shaped photosensitive recording medium so as to be sandwiched between the upper shell and the lower shell, and an opening that is provided in the cartridge main body and exposes the photosensitive recording medium to the outside. A recording / reproducing system that performs recording / reproduction on a photosensitive recording medium cartridge having a shutter attached to the cartridge body so as to be movable between a closed position for closing the opening and an open position for opening the opening. The RFID tag is mounted in the cartridge body at an outer peripheral portion of the disk housing portion in a posture in which the data communication surface is inclined with respect to the insertion direction of the photosensitive recording medium cartridge into the apparatus in the cartridge body. A recording / reproducing system characterized in that information is read from and written to.

  According to the above configuration, identification information used for distribution or management on a library is stored in an RFID tag that can read and write data by wireless communication. Since the RFID tag can be made much more compact than an existing barcode, it is not necessary to secure a large occupied space for mounting, and the cartridge is a thin rectangular box with a thickness of several millimeters. Even the main body can easily fit within the thickness dimension. Therefore, the equipment position of the RFID tag storing the identification information can be selected relatively freely without being limited to the front or back surface of the cartridge, and the degree of freedom of the packaging design such as the packaging container is reduced due to the provision of the identification information. There is no.

Also, identification information can be read from the RFID tag without contact with the cartridge by wireless communication. For example, if the data communication surface of the RFID tag is directed to the side end surface on the insertion direction side of the device, a large number of information can be read. Even in a state where the cartridges are aligned and accommodated so that the front and back surfaces of the cartridges are stacked, identification information can be read simply by pointing the reader of the RFID management system toward the side end surface of the cartridge within the allowable communication distance.
Therefore, when a large number of cartridges 2 are aligned and accommodated so that the front and back surfaces thereof overlap each other, the identification information can be easily read without taking out the cartridges one by one from the alignment position. Workability is improved.

  In addition, the RFID tag storing the identification information is housed in the cartridge body and is not exposed on the surface, so it differs from the barcode sticker attached to the surface of the cartridge due to rubbing during handling. The identification information is not lost in the middle due to the peeling of the seal, and high reliability can be secured for maintaining the identification information even in applications where reading of the identification information is frequently repeated.

  In addition, since the identification information stored in the RFID tag can be read in a non-contact manner through communication by wireless communication, the number of times of contact with the cartridge does not increase for reading the identification information. Accordingly, it is possible to prevent the cartridge from being damaged due to an impact caused by inadvertent contact, or the shutter mounted on the cartridge from moving to adversely affect the light shielding performance and dustproof performance of the cartridge. That is, the cartridge is not damaged for reading out the identification information, and the light shielding performance and dust-proof performance of the cartridge are not deteriorated. The identification information given to the cartridge can be used for easy distribution or management on the library. Can be.

  In addition, since the RFID tag is provided in the cartridge body, data communication can be normally performed even if the incident angle of the radio wave on the data communication surface is within an allowable range, even if it is not directly in front of the data communication surface. Therefore, in the configuration in which the data communication surface of the RFID tag is inclined with respect to the direction in which the cartridge is inserted into the device as in the above configuration, the identification is also made from the direction orthogonal to the insertion direction, for example, in addition to the direction into the device. When information can be read and communication means for communicating with the RFID tag is provided on the apparatus side where the cartridge is mounted, the degree of freedom of installation of the communication means is improved and the communication means can be easily arranged.

  In the above-described photosensitive recording medium cartridge, if the inclination angle of the data communication surface of the RFID tag is set to 45 ° with respect to the insertion direction of the photosensitive recording medium cartridge into the apparatus, the cartridge is mounted. When the communication means for communicating with the RFID tag is provided on the apparatus side, the same is true from both the position facing the cartridge 2 in the direction of insertion into the apparatus and the position facing the direction orthogonal to the insertion direction. The identification information can be read with this sensitivity, and the communication sensitivity can be prevented from lowering due to the change of the installation position of the communication means on the apparatus side.

  In the photosensitive recording medium cartridge according to the present invention, the identification information can be recorded on the RFID tag provided inside the cartridge body, and the identification information can be read in a non-contact manner with respect to the photosensitive recording medium cartridge. . For this reason, the cartridge is not inadvertently contacted for reading the identification information, and the shutter mounted on the cartridge body is not moved or soiled by an impact at the time of contact. Therefore, management on distribution or on the library can be facilitated without affecting the light shielding performance and dustproof performance of the photosensitive recording medium cartridge. In addition, since the cartridge main body is equipped with the RFID tag, if the incident angle of the radio wave on the data communication surface is within an allowable range, data communication can be normally performed even if it is not directly in front of the data communication surface. Therefore, in the configuration in which the data communication surface of the RFID tag is inclined with respect to the direction in which the cartridge is inserted into the device as in the above configuration, the identification is also made from the direction orthogonal to the insertion direction, for example, in addition to the direction into the device. When information can be read and communication means for communicating with the RFID tag is provided on the apparatus side where the cartridge is mounted, the degree of freedom of installation of the communication means is improved and the communication means can be easily arranged.

Preferred embodiments of a photosensitive recording medium cartridge (hereinafter abbreviated as “cartridge”) according to the present invention will be described below in detail with reference to the drawings.
1 to 3 are perspective views showing an external shape of a cartridge according to an embodiment of the present invention, FIG. 4 is an exploded perspective view showing a configuration of the cartridge shown in FIG. 1, and FIG. 5 is a cartridge main body shown in FIG. FIG. 6 is a cross-sectional view cut along the cartridge loading direction A shown in FIG. 1, and FIG. 7 is a cross-sectional view cut along a direction perpendicular to the cartridge loading direction A shown in FIG. is there.

  The cartridge 2 of this embodiment is a hologram in which a disk-shaped hologram recording medium (hereinafter referred to as a recording disk) 4 which is a photosensitive recording medium is rotatably accommodated in a disk accommodating portion 3 provided inside. This is a recording medium cartridge. The recording disk 4 is always handled while being accommodated in the cartridge 2.

  The recording disk 4 is a photosensitive recording medium in which a hole is formed in the center part to form a disk, and a hologram recording layer made of a photosensitive material is provided on both sides. On this hologram recording layer, for example, data is recorded in a multi-layered manner as interference fringes of laser light by laser light in the wavelength range of green 532 nm to blue 405 nm. A reinforcing material may be added to the hole of the recording disk 4.

  Openings 7 and 8 for exposing the recording disk 4 accommodated in the disk accommodating portion 3 to the outside are formed on the upper surface and the lower surface of the cartridge 2. These openings 7 and 8 are normally closed by a shutter 10 that is movably provided outside the cartridge 2, and are opened by moving the shutter 10 toward the open position in the arrow B direction. The shutter 10 is biased by a spring in the direction of arrow C, which is a closed position, and is locked at the closed position by lock mechanisms 11 and 12 provided on both sides of the cartridge 2 so as to operate independently. Therefore, the shutter 10 does not move due to vibration or impact on the cartridge 2 and the openings 7 and 8 are not opened carelessly.

  The cartridge 2 is inserted from the loading direction A into a cartridge slot provided in a recording / reproducing apparatus that records and reproduces data on the recording disk 4. The cartridge 2 loaded in the recording / reproducing apparatus is positioned by positioning holes 15 provided at both ends, the shutter 10 is moved to the open position, and the openings 7 and 8 are opened. For example, when the cartridge 2 is loaded in the apparatus in the state shown in FIG. 1, the pickup unit of the apparatus is inserted into the cartridge 2 from the opening 8 on the lower surface, and data is transferred to the hologram recording layer on the lower surface of the recording disk 4. Recorded or played back. As shown in FIG. 2, when the cartridge 2 is turned upside down and loaded into the apparatus, a pickup unit is inserted from the opening 7 arranged on the lower surface, and data is transferred to the hologram recording layer on the upper surface of the recording disk 4 in FIG. Is recorded or played back.

  In the recording / reproducing apparatus, a lock release mechanism for releasing the lock mechanisms 11 and 12 of the cartridge 2 and a shutter opening / closing mechanism for moving the shutter 10 between a closed position and an open position are incorporated. As shown in FIG. 3, the lock release mechanism moves the release jigs 18 and 19 in the axial direction in the apparatus, and the release engagement portions 20 and 21 of the lock mechanisms 11 and 12 provided on both surfaces of the cartridge 2, respectively. The jigs 18 and 19 are engaged with each other. The release engaging portions 20 and 21 have, for example, a three-pronged shape, and the release jigs 18 and 19 have three engagements so that they can be easily engaged with the release engaging portions 20 and 21. A combination pin 23 is provided.

  When the release jigs 18 and 19 are engaged with the release engaging portions 20 and 21 and rotated counterclockwise, the lock mechanisms 11 and 12 are released. Next, the shutter opening / closing mechanism inserts a driving pin into the hole 10 a formed in the side surface of the shutter 10 and moves it in the opening direction B. As a result, the shutter 10 is slid and the openings 7 and 8 on both sides of the cartridge 2 are opened as shown in FIG.

  FIG. 4 is an exploded perspective view showing the configuration of the cartridge 2. The cartridge 2 includes a cartridge main body 25 that rotatably accommodates the recording disk 4, a shutter 10 that opens and closes the openings 7 and 8 on both sides of the cartridge main body 25, and lock mechanisms 11 and 12 that are incorporated in the cartridge main body 25. Consists of. Since the lock mechanism 12 is plane-symmetric with the lock mechanism 11 and has the same configuration and structure, illustration and detailed description thereof are omitted.

  As shown in FIG. 5, the cartridge body 25 includes a substantially plate-like lower shell 30 and an upper shell 31 joined to the upper surface of the lower shell 30. The lower side 30 and the upper shell 31 are formed of the same or similar thermoplastic plastic to which a light shielding material and a lubricant are added. In the present embodiment, the lower shell 30 is associated with the first shell, and the upper shell 31 is associated with the second shell.

  Various substances can be added as the light-shielding substance. For example, 0.01 to 5.00% by weight is preferably added depending on the light-shielding substance to be used. For example, carbon black can be used as the light-shielding substance. The amount of carbon black added is preferably 0.01 to 2.00% by weight. If the added amount exceeds 0.01% by weight, the effect of improving the light-shielding property and the physical strength is exhibited, but if the added amount exceeds 2.00% by weight, the physical strength is lowered.

  As the lubricant, for example, a silicone-based lubricant can be used. Since the frictional resistance is reduced by the addition of the silicone lubricant, the generation of shavings due to the movement of the shutter 10 can be reduced. Further, it is possible to reduce the generation of shavings when the recording disk 4 and the inner wall of the cartridge 2 come into contact with each other due to an impact during transportation. Furthermore, the handleability of the insertion performance into the device is improved. Moreover, since fluidity | liquidity improves, workability, such as kneadability at the time of shaping | molding and injection molding, also improves.

  The addition amount of the silicone lubricant is preferably 0.1 to 3.0% by weight. Less than 0.1% by weight is less effective, and more than 3.0% by weight results in excessive fluidity and slippage between the screw and resin during kneading and molding, resulting in poor workability and bleeding on the product surface. This is because it may adhere to the recording disk 4 or the user's hand and cause problems in handling and appearance. In addition, when using copolymer silicone, since the said malfunction becomes difficult to produce, it is possible to add to 5.0 weight%.

  On the inner surface of the lower shell 30, as shown in FIG. 5, a substantially circular disc accommodating portion 3 for accommodating the recording disc 4 and a ridge shape so as to surround the periphery of the disc accommodating portion 3 are provided. A first recess 34, a second recess 35 provided around the entire periphery of the edge, a light shielding wall 36 surrounding the positioning hole 15, and a notch 37 serving as a space for storing the spring of the shutter 10 are provided. It has been. In the cutout portion 37, a spring hooking piece 38 on which one end of the spring of the shutter 10 is hung is integrally provided.

Further, in the case of the cartridge 2 of the present embodiment, as shown in FIGS. 4 and 5, the data communication surface 100 a is inclined in the cartridge main body 25 with respect to the insertion direction A of the cartridge 2 into the apparatus. The RFID tag 100 is equipped.
This RFID tag 100 is a thin label type or card type wireless IC chip whose vertical and horizontal dimensions are, for example, 4 × 10 mm or less, and is used for distribution of its identification code and the title of data stored in the recording disk 4. Alternatively, identification information used for management on the library can be stored, and the stored information can be transmitted and received with a reader of the management system by radio waves or electromagnetic waves.

  In addition, the RFID tag 100 according to the present embodiment uses a type that can be used semipermanently without a battery by a non-contact power transmission technique from the reader side of the management system. Moreover, a thing as small as possible is desirable. For example, a communication frequency band in the microwave (2.45 GHz) region and a communication distance of about several millimeters to several centimeters are used.

In the case of the present embodiment, as shown in FIG. 8, the RFID tag 100 is fixed to the inclined top surface of the tag support portion 101 integrally formed on the inner surface of the lower shell 30 with an adhesive.
The mounting position of the tag support portion 101 is the outer peripheral portion of the disc storage portion 3, and specifically, in the extra space between the first recess 34 and the second recess 35.
In the present embodiment, the inclination angle θ of the data communication surface 100a of the RFID tag 100 is set to 45 ° with respect to the insertion direction A of the cartridge 2 into the apparatus.

  Further, on the inner surface of the upper shell 31, an upper surface portion 41 that constitutes an upper surface of the disk housing portion 3 of the lower shell 30 and a first convex portion 42 that is inserted into the first concave portion 34 of the lower shell 30. And a second convex portion 43 inserted into the second concave portion 35 and a light shielding wall 44 provided so as to surround the positioning hole 15 and inserted into the light shielding wall 36.

  When the recording disk 4 is placed on the disk housing portion 3 and the upper shell 31 is superimposed on the upper surface of the lower shell 30, the first convex portion 42 is fitted into the first concave portion 34. As shown in FIG. 9, which is an enlarged view of the arrow D portion in FIG. 6, the tip 42 a of the first convex portion 42 fitted in the first concave portion 34 faces the inner surface 30 a of the lower shell 30, The front end 43a abuts on the inner surface 30a of the lower shell 30 to form a fitting structure.

  Since the outer periphery of the disk housing portion 3 is surrounded by a labyrinth-shaped light shielding structure, light and dust do not enter the disk housing portion 3 from the joint of the lower shell 30 and the upper shell 31. Further, as shown in the cross-sectional view of FIG. 10, the outer periphery of the positioning hole 15 also has a labyrinth-like light shielding structure formed by fitting the two light shielding walls 36 and 44, so that light and dust enter from the positioning hole 15. Never do. Further, since the positioning hole 15 is disposed outside the light shielding structure including the first concave portion 34 and the first convex portion 42, the light shielding property and dustproof property of the disk housing portion 3 are not affected.

  The second convex portion 43 of the upper shell 31 is fixed to the inner surface 30a of the lower shell 30 by ultrasonic welding. Thereby, since the lower shell 30 and the upper shell 31 are firmly joined, there is no gap between the joints of the two. Further, when ultrasonic welding is performed, the plastic powder may be scattered around, but by performing the ultrasonic welding within the second recess 35, the scattering can be minimized and the recording disk 4 can be prevented from being damaged.

  If the lower shell 30 and the upper shell 31 are ultrasonically welded after the shutter 10 and the lock mechanism 11 are incorporated into the cartridge body 25, other parts such as the shutter 10 may be welded together. In order to prevent this, it is preferable to use a different kind of plastic from the lower shell 30 and the upper shell 31 as the material of other parts such as the shutter 10.

  In order to more reliably join the lower shell 30 and the upper shell 31 by ultrasonic welding, it is preferable to provide a protruding energy director 47 at the tip 43a of the second convex portion 43 as shown in FIG. . When the energy director 47 is provided and ultrasonic welding is performed, the energy of the ultrasonic waves is concentrated on the energy director 47, so that the second convex portion 43 and the lower shell 30 can be welded more firmly. The ultrasonic welding between the lower shell 30 and the upper shell 31 may be performed on the entire circumference of the second convex portion 43 or may be performed in a spot manner at regular intervals.

The shutter 10 is formed of a plastic different from the lower shell 30 and the upper shell 31. In the same way as the plastic used for molding the lower shell 30 and the upper shell 31, a light shielding material and a lubricant may be added to this plastic.
As shown in FIG. 12, the shutter 10 is formed integrally with the base portion 50 so as to sandwich the base portion 50 disposed on the side surface of the cartridge main body 25 on the loading direction A side and the upper and lower surfaces of the cartridge main body 25. It consists of a side shutter plate 51 and an upper shutter plate 52. A spring hooking piece 56 on which one end of the shutter spring 54 is hung is integrally provided on the inner surface of the base portion 50. The other end of the shutter spring 54 is hooked on the spring hooking piece 38 of the lower shell 30 and stored in the notch 37, and urges the shutter 10 toward the closed position.

On the outer surfaces of the lower shell 30 and the upper shell 31, there are slits 60, 61 for accommodating the side edges 51a, 52a in the closing direction C of the shutter plates 51, 52, and the rear edges 51b, 52b in the loading direction A. And slits 62 and 63 (see FIGS. 1 and 2) are respectively formed. Further, as shown in FIG. 7, each shutter plate 51, 52 includes a first light shielding plate portion 51c, 52c that slides to open and close the openings 7, 8, and a first light shielding plate portion 51c, 52c. The second light-shielding plate portions 51d and 52d that are vertically erected at the tip of the side that moves in the direction in which the shutter 10 is opened, and the second light-shielding plate portions 51d and 52d that are vertically erected in the closing direction The third light shielding plate portions 51e and 52e are formed. The side edge in the opening direction B of each shutter plate 51, 52 functions as a substantially U-shaped bent portion in a section in the opening / closing direction.
As shown in FIG. 7, when the shutter 10 is in the closed position, the first shell plate 51, 52 on the lower shell 30 and the upper shell 31 is opposed to the side edge in the opening direction B. Projections 65 and 66 inserted between the light shielding plate portions 51c and 52c and the third light shielding plate portions 51e and 52e are formed, respectively.

  When the shutter 10 is in the closed position, the end edges 51a, 51b and 52a, 52b of the shutter plates 51, 52 are inserted into the slits 60, 62, 61, 63 of the shells 30, 31, respectively. The provided protrusions 65 and 66 enter between the first light shielding plate portions 51c and 52c and the third light shielding plate portions 51e and 52e of the shutter plates 51 and 52, respectively. Thereby, since the cartridge main body 25 and the shutter 10 are also surrounded by the labyrinth-shaped light shielding structure, it is possible to effectively prevent light and dust from entering through the gap between the cartridge main body 25 and the shutter 10.

  As shown in FIG. 6, guide protrusions 51f and 52f are formed on the inner surfaces of the shutter plates 51 and 52 of the shutter 10, and the guide protrusions 51f and 52f are inserted on the outer surfaces of the shells 30 and 31, respectively. Guide grooves 70 and 71 are formed. When the shutter 10 moves on the outer surface of the cartridge body 25, the guide protrusions 51f and 52f move in the guide grooves 70 and 71. As a result, the shutter 10 can move smoothly without being detached from the cartridge body 25. Note that the lower shell 30 and the upper shell 31 and the shutter 10 have no lubricant generated due to friction when the shutter 10 moves because the lubricant is added to the raw material plastic.

  As shown in FIGS. 4 and 13, the lock mechanism 11 incorporated in the upper shell 31 includes a lock mechanism recess 75 formed on the outer surface of the upper shell 31 and connected to the slit 61, and the lock mechanism 11 incorporated in the recess 75. A lock lever 76 and a lock spring 77, and a plate-like lock cover 78 that closes the lock mechanism recess 75. The lock mechanism 11 locks the shutter 10 in the closed position by engaging a lock lever 76 with an engaged claw 52 g formed integrally with the upper shutter plate 52 of the shutter 10.

  The lock lever 76 includes an engagement claw 76a that engages with the engaged claw 52g, a shaft portion 76b that is rotatably inserted into a hole 75a formed in the recess 75 for the lock mechanism, and the above-mentioned tridental shape. The release engaging portion 20 is integrally provided. The lock spring 77 is a torsion spring, and is inserted into the shaft portion 76b. One end of the lock spring 77 is hooked on the lock lever 76, and the other end abuts against the inner wall surface of the lock mechanism recess 75. Energize clockwise. The release engaging portion 20 is exposed through a hole 78a formed in the lock cover 78 so as not to protrude to the outside. Reference numeral 75b in the recess 75 for the lock mechanism is a holding piece that receives the lock lever 76 biased by the lock spring 77 and holds the lock lever 76 in an engaged position where the lock lever 76 is engaged.

  The lock mechanism 12 incorporated in the lower shell 30 includes a lock mechanism recess 80 formed on the outer surface of the lower shell 30 and connected to the slit 60, and a lock lever 81 and a lock spring 82 incorporated in the recess 80. The plate-shaped lock cover 83 closes the lock mechanism recess 80. The lock mechanism 12 locks the shutter 10 in the closed position by engaging a lock lever 81 with an engaged claw 51 g formed integrally with the lower shutter plate 51 of the shutter 10. Each component of the lock lever 12 has the same configuration as that of the lock lever 11, and a detailed description thereof will be omitted.

  In the cartridge 2 described above, identification information used for distribution or management on a library is stored in an RFID tag 100 that can read and write data by wireless communication.

  In the recording / reproducing apparatus according to the present invention, the data communication surface 100a is inclined in the cartridge body 25 with respect to the insertion direction of the photosensitive recording medium cartridge 2 into the apparatus at the outer peripheral portion of the disk housing portion of the cartridge body 25. In this configuration, an information exchange unit that reads and writes information from and to the RFID tag 100 that is installed in a different posture is provided.

Since the RFID tag 100 can be much more compact than an existing barcode, it is not necessary to secure a large occupied space for mounting, and is a thin rectangular box having a thickness dimension of several millimeters. Even the cartridge body 25 can be easily accommodated within the range of the thickness dimension of the cartridge body 25.
Therefore, the installation position of the RFID tag 100 storing the identification information can be selected relatively freely without being limited to the front surface or the back surface of the cartridge 2, and the degree of freedom in the design of a package such as a packaging container is reduced due to the provision of the identification information. There is nothing to do.

Also, identification information can be read from the RFID tag 100 without contact with the cartridge 2 by communication by wireless communication. For example, the data communication surface 100a of the RFID tag 100 is directed to the side end surface on the side A in the insertion direction to the apparatus. As shown in FIG. 14, even if a large number of cartridges 2 are aligned and accommodated in a state where the front and back surfaces of the cartridges 2 are stacked, the reader of the RFID management system is placed on the side end surface of the cartridge 2 within the allowable communication distance. Identification information can be read simply by pointing.
Therefore, when a large number of cartridges 2 are aligned and accommodated so that the front and back surfaces of the cartridges 2 are overlapped, the identification information can be easily read without removing the cartridges 2 from the alignment position one by one. Improved workability.

  Further, the RFID tag 100 storing the identification information is accommodated in the cartridge body 25 and is not exposed on the surface, and therefore, unlike the case of a bar code sticker attached to the surface of the cartridge, rubbing during handling, etc. The identification information is not lost in the middle due to the peeling of the seal due to the above, and high reliability can be ensured in maintaining the identification information even in applications where reading of the identification information is frequently repeated.

  In addition, since the identification information stored in the RFID tag 100 can be read in a non-contact manner through communication by wireless communication, the number of times of contact with the cartridge 2 for reading the identification information does not increase. Accordingly, it is possible to prevent the cartridge 2 from being damaged due to an impact caused by inadvertent contact or the shutter 10 mounted on the cartridge 2 from moving and adversely affecting the light shielding performance and dustproof performance of the cartridge 2. In this way, the cartridge 2 is not soiled for reading the identification information, and the light shielding performance and dustproof performance of the cartridge 2 are not deteriorated. The identification information given to the cartridge 2 is utilized for distribution or on the library. Can be easily managed.

  The RFID tag 100 can normally perform data communication even if it is not directly in front of the data communication surface 100a as long as the incident angle of the radio wave on the data communication surface 100a is within an allowable range. Therefore, in the configuration in which the data communication surface 100a of the RFID tag 100 is inclined with respect to the insertion direction of the cartridge 2 into the apparatus as in the above configuration, in addition to the insertion direction of the apparatus indicated by the arrow Y in FIG. For example, when the identification information can be read from the direction Z orthogonal to the insertion direction Y, and the communication means for communicating with the RFID tag 100 is provided on the apparatus side to which the cartridge 2 is mounted, the degree of freedom of installation of the communication means. And communication means can be easily deployed.

  FIG. 15 shows a state in which a large number of cartridges 2 are arranged and accommodated in a single plane. In such a case, the identification information can be read out without any problem by applying a radio wave of communication to the data communication surface 100a from the direction of arrow Z in the figure.

In the present embodiment, the inclination angle θ of the data communication surface 100a of the RFID tag 100 is set to 45 ° with respect to the insertion direction A of the cartridge 2 into the apparatus.
Therefore, when a communication means for communicating with the RFID tag 100 is provided on the apparatus side to which the cartridge 2 is mounted, the position opposite to the cartridge 2 in the direction of insertion into the apparatus and the direction orthogonal to the insertion direction. Identification information can be read with the same sensitivity from any of the opposing positions, and a decrease in communication sensitivity due to a change in the installation position of the communication means on the apparatus side can be prevented.
