Description

  The present invention relates to a case body having a substantially flat cubic shape, a single tape reel, a cartridge case including an identification tag and a security tag, and an information recording medium including the cartridge case.

  As this type of information recording medium, a tape cartridge disclosed in Japanese Patent No. 3605106 is known. This tape cartridge is a flat cubic tape cartridge that can be mounted on a server or workstation tape drive device, and includes a film-like security tag and a tape identification tag (also referred to as an identification tag). In this tape cartridge, the security tag is arranged at one of the four corners of the flat cubic tape cartridge, and the identification tag is arranged at a diagonal corner of the corner where the security tag is arranged.

  In this case, the identification tag includes a memory and is configured to be able to store management information such as tape cartridge manufacturing information (identification information) and usage history information. On the other hand, the security tag transmits a radio wave of a frequency multiplied by a diode sharing a power supply unit with the dipole antenna, a diode that multiplies the frequency of the radio wave received by the dipole antenna, and a dipole antenna that receives a radio wave of a specific frequency. A loop antenna is provided so that when a tape cartridge containing the security tag is placed in a predetermined inspection area, it can be notified to the outside that it is in the inspection area.

According to this tape cartridge, it is possible to monitor removal from a predetermined security area by incorporating a security tag. Further, since the security tag is arranged at the corner opposite to the corner where the identification tag is arranged, it can be arranged at a position farthest from the identification tag that generates electromagnetic identification information, that is, an optimum position. .
Japanese Patent No. 3605106 (page 3-4, FIG. 3)

  However, the conventional tape cartridge has the following problems. That is, for this type of tape cartridge, the inspection for the built-in security tag and identification tag is performed in the inspection process after the assembly is completed, but the assembled tape cartridges are closely arranged. It is transported and stored in the transported state. For this reason, in order to surely carry out the inspection for the security tag and the identification tag in one tape cartridge to be inspected, the inspection radio wave (in which the security tag and the identification tag in another adjacent tape cartridge do not operate) A weak radio wave) is generated locally and transmitted to the tape cartridge to be inspected.

  However, in the conventional tape cartridge, since the security tag and the identification tag are disposed at different corners (each corner at a diagonal position), a weak inspection radio wave is transmitted to one corner where the security tag is disposed. It is necessary to transmit to each of the other corners where the identification tag is arranged, and the inspection of the security tag and the inspection of the identification tag are performed separately and separately in two times by changing the direction of the tape cartridge. As a result of the necessity, there is a problem that the inspection is complicated.

  On the other hand, electromagnetic interference, which has been a problem when the security tag and the identification tag are arranged close to each other, has been greatly improved in recent years due to the improvement of both. Even if it is set up, there is no problem.

  The present invention has been made in view of such problems, and a main object of the present invention is to provide a cartridge case and an information recording medium that can be easily inspected for an identification tag and a security tag.

  As shown in FIG. 1, the case main body 2 is formed in a substantially flat cube having a lower case 11 and an upper case 12 that are formed in a square dish shape in plan view and can be fitted to each other. The tape reel 3 is rotatably accommodated in the internal space formed in the 12 fitted state.

  In this case, as shown in FIGS. 1 and 2, the lower case 11 includes a bottom plate 11a and four side walls 11b, 11c, 11d, and 11e. Also, a notch 11f that forms a tape outlet 2a for drawing out the magnetic tape wound around the tape reel 3 to the outside is formed in one side wall 11b. In addition, three arc-shaped wall portions (hereinafter also referred to as “arc-shaped walls”) 11g, 11h, and 11i are erected on the other three corners excluding the corner near the notch 11f among the four corners of the bottom plate 11a. Has been. Both ends of each of the arcuate walls 11g, 11h, and 11i are connected to two side walls 11b and 11c, side walls 11c and 11d, and side walls 11d and 11e that are adjacent to each other. As a result, the three corners other than the corner near the notch 11f in the four corners of the lower case 11 are partitioned regions having a substantially triangular shape in plan view surrounded by two side walls and one arcuate wall. A1, A2, and A3 are formed, respectively. The tape reel 3 is housed in the central region A4 of the lower case 11 surrounded by the side walls 11b, 11c, 11d, 11e and the arcuate walls 11g, 11h, 11i.

  On the other hand, as shown in FIGS. 1, 3, and 4, the upper case 12 includes a top plate 12a and four side walls 12b, 12c, 12d, and 12e. Moreover, the notch 12f which comprises the tape drawer 2a is formed in the one side wall 12b. In addition, three arc-shaped wall portions (hereinafter also referred to as “arc-shaped walls”) 12g, 12h, and 12i stand on the other three corners except for the corner near the notch 12f among the four corners of the top plate 12a. It is installed. Both ends of each of the arcuate walls 12g, 12h, and 12i are connected to two side walls 12b and 12c, side walls 12c and 12d, and side walls 12d and 12e that are adjacent to each other. As a result, the other three corners except for the corner near the notch 12f among the four corners of the upper case 12 are planes surrounded by two side walls and one arcuate wall in the same manner as the lower case 11. Partition areas B1, B2, and B3 each having a substantially triangular viewing shape are formed. The tape reel 3 is housed in the central region B4 of the upper case 12 surrounded by the side walls 12b, 12c, 12d, 12e and the arcuate walls 12g, 12h, 12i.

  Further, the side wall 11c of the lower case 11 and the side wall 12c of the upper case 12 constitute the rear wall of the case body 2 (the wall surface on the rear side in the insertion direction of the tape cartridge 1), and the respective surfaces are labels (index labels). Functions as a sticking surface.

  As illustrated in FIG. 1, the tape reel 3 includes a hub 21, a lower flange 22, an upper flange 23, and a metal plate 24. The hub 21 is formed in a bottomed cylindrical shape that is open on the upper end side and closed on the lower end side. The lower flange 22 is attached to the lower end portion of the hub 21, and the upper flange 23 is attached to the upper end portion of the hub 21. The metal plate 24 is formed in a disc shape and is attached to the lower end surface of the hub 21. The tape reel 3 configured as described above is configured such that a magnetic tape can be wound around the outer peripheral surface of the hub 21 sandwiched between both flanges 22 and 23.

  As shown in FIG. 1, the spring 6 is constituted by a coil spring and is disposed between the upper case 12 and the lock member 5 and biases the lock member 5 toward the tape reel 3 side. As shown in the figure, the door member 7 is formed in a thin plate shape capable of closing the tape outlet 2a, and is formed in guide grooves (not shown) formed in the side wall 11b of the lower case 11 and the side wall 12b of the upper case 12, respectively. Slidably).

  The identification tag 8 includes a memory, a memory control circuit, a communication circuit, and an antenna (all not shown). In this case, the antenna is configured to be able to transmit and receive radio waves of a specific frequency (first frequency), and the communication circuit outputs information received via the antenna to the memory control circuit, and information input from the memory control circuit to the antenna. It is configured to be able to transmit via. The memory control circuit stores information input from the communication circuit in the memory and outputs information read from the memory to the communication circuit. The identification tag 8 configured in this way stores manufacturing information (identification information) of the tape cartridge 1, usage history information, partition information on the magnetic tape, and the like as management information. As shown in FIGS. 1 and 2, the identification tag 8 is disposed (attached) in the partition area A1 of the lower case 11.

  As an example, the security tag 9 includes an elastic film body 9a, a back plate 9b, and a diode 9c, as shown in FIG. In this case, the elastic film body 9a uses, for example, a copper foil and an elastic wire to share a power supply unit with a dipole antenna that receives radio waves of a specific frequency (second frequency different from the first frequency). A loop antenna (none of which is shown) for transmitting radio waves having a frequency multiplied by the diode 9c is formed. The diode 9c is mounted on the elastic film body 9a and multiplies the frequency of the radio wave received by the dipole antenna. As shown in FIG. 4, the elastic film body 9a and the back plate 9b are connected to each other at one end. As shown in the figure, the security tag 9 is disposed in the partition region B1 of the upper case 12 with the elastic film body 9a elastically deformed with respect to the back plate 9b. In this case, the security tag 9 is attached in the partition area B1 by the back plate 9b being pressed against the inner surface of the side wall 12b by the elastic force of the elastic film body 9a. The security tag 9 attached to the upper case 12 in this way indicates that when the tape cartridge 1 containing the security tag 9 is placed in a predetermined inspection area, it exists in the inspection area. It has a function to notify. Since the specific frequency (second frequency) for the security tag 9 is set to a frequency different from the specific frequency (first frequency) for the identification tag 8 as described above, there is no electromagnetic interference between them. It is maintained in a state that does not occur.

  Thus, since the identification tag 8 is disposed in the partition area A1 of the lower case 11 and the security tag 9 is disposed in the partition area B1 of the upper case 12, the lower case 11 and the upper case 12 As shown in FIG. 5, in the case main body 2 constructed by fitting the two, the tape cartridge 1 has a thickness of the tape cartridge 1 at one of the four corners (one corner) C1 when viewed from above (see FIG. 5). The identification tag 8 and the security tag 9 are arranged close to each other along the direction (which is also the thickness of the case body 2) (the vertical direction in the figure).

  The erroneous erasure prevention plug 10 is used to prevent erroneous erasure of data recorded on the information recording medium 1, and is divided between the partition area A 2 of the lower case 11 and the partition area B 2 of the upper case 12 in the case body 2. It is disposed in the space to be configured. Further, the erroneous erasure prevention plug 10 is configured to be slidable between the erasure allowable position and the erasure prohibition position along the side wall 11c of the lower case 11 and the side wall 12c of the upper case 12 in this space. .

  Further, for the tape cartridge 1 having the above-described configuration, various inspections are performed in the inspection process after the assembly is completed, and those subjected to each inspection are shipped as non-defective products. In this case, as one of the inspections, an inspection for the built-in identification tag 8 and security tag 9 is performed. In this inspection, the inspection radio waves (the first frequency radio wave and the second frequency radio wave) are simultaneously transmitted to one corner C1 of the tape cartridge 1 in which the identification tag 8 and the security tag 9 are disposed. Upon receiving the transmitted radio wave, it is checked once (simultaneously) whether or not each tag 8, 9 operates normally.

  As described above, according to the tape cartridge 1, the identification tag 8 and the security tag 9 are disposed at one corner C1 (see FIGS. 1 to 5) of the four corners of the case body 2, respectively. The security tag 9 can be disposed at a close position. Therefore, as described above, the inspection for the identification tag 8 and the security tag 9 is performed once only by transmitting each inspection radio wave toward the corner C1 of the tape cartridge 1 in which the identification tag 8 and the security tag 9 are disposed. Therefore, the tags 8 and 9 can be easily inspected. In addition, since the identification tag 8 and the security tag 9 are arranged at one corner C1 of the case body 2, the space formed in the corner C1 of the case body 2 (the partition area A1 of the lower case 11 and the partition of the upper case 12). The identification tag 8 and the security tag 9 can be disposed at close positions in a state in which interference with the tape reel 3 is reliably prevented using the space formed by the area B1.

  In addition, this invention is not limited to said structure. For example, while the identification tag 8 is disposed in the partition area A1 of the lower case 11 and the security tag 9 is disposed in the partition area B1 of the upper case 12, the partition areas A1, B1 are described. It is also possible to adopt a configuration in which both the identification tag 8 and the security tag 9 are disposed on either of them. In addition, the example in which the identification tag 8 and the security tag 9 are arranged in one corner C1 in which the partition areas A1 and B1 are formed in the four corners of the case body 2 has been described above. As shown in FIGS. A configuration in which the partition areas A2 and B2 are formed in one corner C2 and a configuration in which the partition areas A3 and B3 are formed in one corner C3 may be employed.
