Description

  The present invention relates to a cartridge case in which a tape reel and a security tag are arranged in a case body, and an information recording medium including the cartridge case.

As an information recording medium for backing up a large amount of data recorded in a computer system, a one-reel type information recording medium is known. In this case, for example, an information recording medium (for example, Japanese Patent No. 3605106) in which a security tag is disposed in the case main body as a means for preventing illegal outflow of the data from the storage location and preventing outflow of data. Is disclosed. In this type of information recording medium, generally, the space between the partition plate in the case main body and the side plate of the case main body that partitions the housing portion in which the tape reel is stored, that is, the corner space in the case main body. A security tag is provided.

Japanese Patent No. 3605106 (page 3, FIG. 2)

  However, the conventional information recording medium has the following problems. That is, in this type of information recording medium, in order to prevent damage to the security tag due to rattling, the security tag is generally attached to the inner surface of the case body using an adhesive or adhesive tape. It is fixed. However, for example, when fixing a security tag composed of a coil and a capacitor by this method, there is a problem that it is difficult to securely fix the security tag because there are relatively few flat portions that can be used as an adhesive surface. There is a point. Also, with this method, there is a risk that the adhesive or the adhesive tape will deteriorate over time while the information recording medium is stored for a long period of time, and the security tag will be peeled off from the inner surface of the case body, causing rattling. In this case, a method of fixing the security tag by attaching a security tag to the holder and screwing the holder to the case body is also conceivable. However, with this method, although it is possible to securely fix the security tag, there is a problem that it is somewhat difficult to improve production efficiency due to the addition of the screwing step.

  The present invention has been made to solve such problems, and has as its main object to provide a cartridge case and an information recording medium that can securely fix a security tag while improving production efficiency.

  In order to achieve the above object, a cartridge case according to the present invention includes a case main body having a lower case and an upper case that can be fitted to each other, and forming a substantially flat cube in the fitted state of the two cases, A tape reel that is rotatably accommodated in a housing section partitioned by a partition plate formed on the bottom plate, a top plate, a side plate of the case body, and any corner in the case body surrounded by the partition plate A security case disposed in a predetermined area of the unit, wherein the security tag is a holder that abuts against the bottom plate, the top plate, the side plate, and the partition plate and whose movement is restricted. In the attached state, it is arranged in the predetermined area.

  In this case, the case body is configured to include the columnar protrusions that are erected on at least one of the bottom plate and the top plate and protrude into the predetermined region, and the predetermined region is in contact with the columnar protrusions. The holder can be disposed on the surface.

  In addition, the security tag is configured to have a curved shape by including a cylindrical coil portion around which a winding is wound and a capacitor in which lead terminals are connected in parallel to both ends of the winding of the coil portion. A holder body that holds the coil portion that is formed in a substantially semi-cylindrical shape by a body portion and wall portions disposed at both ends of the body portion and is fitted from the opening portion, and the lead terminal of the capacitor with a single touch. The holder can be configured by including a pair of holding portions that can be fitted and hold the fitted lead terminals.

  A first holding piece standing on the outer peripheral surface of the holder main body so as to protrude from the holder main body; and a first holding piece standing on the outer peripheral surface so as to be separated from the first holding piece by a predetermined distance. Each holding part can be configured with a second holding piece having a claw part protruding toward the one holding piece and formed at the tip.

  Furthermore, the structure which formed the slit in at least one of the said both wall parts of the said holder is employable.

  Moreover, the structure which formed the rib which protrudes inside the said holder main body on the inner peripheral surface of the said edge part vicinity of the said opening part in the said edge part is employable.

By abutting, the security tag can be fixed to the case body together with the holder. For this reason, according to the cartridge case and the information recording medium, unlike the conventional fixing method using an adhesive or an adhesive tape, even if the security tag has few flat portions that can be used as an adhesive surface, the security tag is used as a case. It can be securely fixed to the main body. Further, according to the cartridge case and the information recording medium, since the security tag is fixed using the holder without using the adhesive or the adhesive tape, the security tag may be peeled off from the case body due to the aging of the adhesive or the adhesive tape. Unlike the conventional fixing method described above, a state where the security tag is securely fixed can be maintained for a long period of time. Furthermore, according to the cartridge case and the information recording medium, since a screwing process is unnecessary, the result is that the holder can be fixed in a short time and easily compared with the method of fixing the holder to the case body by screwing. , Production efficiency can be improved sufficiently.

  Further, according to the cartridge case and the information recording medium according to the present invention, the holder and the security tag are more securely fixed by arranging the holder in the predetermined region in a state of being in contact with the columnar protrusion of the case body. Thus, the movement of the security tag can be surely prevented.

  Also, according to the cartridge case and the information recording medium of the present invention, a pair of holder bodies that are formed in a substantially semi-cylindrical shape and hold the coil portion of the security tag and a lead terminal of the capacitor in the security tag is fitted and held with one touch. Since the holder is provided with the holding portion, the coil portion and the capacitor can be securely and easily attached to the holder in a short time. Therefore, according to the cartridge case and the information recording medium, it is possible to more securely fix the security tag while further improving the production efficiency.

  Furthermore, according to the cartridge case and the information recording medium according to the present invention, the first holding piece standing on the outer peripheral surface of the holder body so as to protrude from the holder body and the first holding piece are spaced apart from each other by a predetermined distance. With a relatively simple configuration, the holding portion is configured to include a claw portion standing on the outer peripheral surface of the holder body and projecting toward the first holding piece and having a second holding piece formed at the tip. However, it is possible to achieve the one-touch fitting of the lead terminal and the reliable holding of the fitted lead terminal.

  Further, according to the cartridge case and the information recording medium of the present invention, since the slit is formed in at least one of the both wall portions of the holder, the holder main body is elastically deformed when the coil portion is fitted into the holder main body. As a result of the opening being widened, the operation of fitting the coil portion into the holder body can be reliably and easily performed.

  Further, according to the cartridge case and the information recording medium according to the present invention, the rib projecting inward of the holder main body is formed on the inner peripheral surface in the vicinity of the opening at the end portion of the trunk portion, and thus is fitted into the holder main body. As a result of the ribs being able to reliably regulate the movement of the coil portion toward the opening, the coil portion can be prevented from falling off the holder body, and the coil portion can be reliably held.

It is possible to easily perform the fitting operation of 9a. Further, in the holder 10, ribs 61c are formed on the inner peripheral surface 61b of the body 61 in the vicinity of the opening 51a. For this reason, since the rib 61c restricts the movement of the coil portion 9a toward the opening 51a, the coil portion 9a fitted in the holder main body 51 is prevented from falling off from the opening 51a, and the coil portion 9a is It is possible to hold it securely.

  Next, as shown in FIGS. 4 and 5, the lead terminal 44 of the capacitor 9 b is fitted into the holding portion 52 of the holder 10. In this case, the distal end portion of the first holding piece 71 is pushed by pushing the lead terminal 44 from the gap between the holding pieces 71 and 72 constituting the holding portion 52 toward the base end side of the holding pieces 71 and 72. The holding pieces 71 and 72 are elastically deformed in such a direction that the claw portions 72a of the second holding piece 72 are separated from each other. Subsequently, by pushing the lead terminal 44 further toward the base end side than the claw portion 72a, the elastic deformation is released, and the distal end portion of the first holding piece 71 and the claw portion 72a of the second holding piece 72 come close to each other. . As a result, the lead terminal 44 is fitted into the holding portion 52 and is held by the holding portion 52. In this case, it is possible to attach (hold) the lead terminal 44 to the holding portion 52 simply by pushing the lead terminal 44 (with one touch), so that the attaching operation can be easily performed in a short time. Next, both ends 43a and 43b of the winding 9c are soldered to the lead terminals 44 and 44 of the capacitor 9b. Thus, the setting of the security tag 9 with respect to the holder 10 is completed.

  Next, as shown in FIGS. 6 and 7, one wall 62 of the holder body 51 abuts against the bottom plate 11 a of the lower case 11, and the bottom 51 b side of the holder body 51 is the partition plate 11 i and the columnar protrusion 32 of the lower case 11.

It arranges in.

  Subsequently, as shown in FIG. 7, the lower case 11 and the upper case 12 in which the respective components are assembled (arranged) are fitted. At this time, the other wall portion 62 of the holder main body 51 abuts on the top plate 12 a of the upper case 12, the bottom 51 b side of the holder main body 51 abuts on the partition plate 12 i of the upper case 12, and the holding portion 52 is the upper case 12. Of the side plate 12d (not shown in the figure). Next, both cases 11 and 12 are screwed. Thus, the assembly of the tape cartridge 1 is completed. In this case, as shown in FIGS. 6 and 7, in this state, the holder 10 contacts the bottom plate 11a, the top plate 12a, the side plates 11d and 12d, the partition plates 11i and 12i, and the columnar protrusions 31 and 32 of the case body 2. In contact therewith, the movement in the vertical direction (direction toward the top plate 12a and the bottom plate 11a) and the horizontal direction (direction toward the side plates 11d and 12d, the partition plates 11i and 12i and the columnar protrusions 31 and 32) are restricted. . Accordingly, the movement of the security tag 9 set in the holder 10 in the vertical direction and the horizontal direction together with the holder 10 is reliably restricted.

  Here, in the tape cartridge 1, as described above, the holder 10 in which the security tag 9 is set is brought into contact with the bottom plate 11a, the top plate 12a, the side plates 11d and 12d, the partition plates 11i and 12i, and the columnar protrusions 31 and 32. The movement of the security tag 9 and the holder 10 is restricted by contacting. For this reason, in this tape cartridge 1, unlike the fixing method using an adhesive or an adhesive tape, the security tag 9 constituted by the coil portion 9a and the capacitor 9b and having a small planar portion that can be used as an adhesive surface is provided with the case body 2 It is possible to securely fix to. Further, unlike the conventional fixing method in which the security tag 9 may be peeled off from the case body 2 due to aging deterioration of the adhesive or the adhesive tape, the state where the security tag 9 is securely fixed is maintained for a long period of time. Is possible. Further, in this tape cartridge 1, the holder 10 is screwed by bringing the holder 10 into contact with the plates 11a, 12a, 11d, 12d, 11i, 12i and the columnar protrusions 31, 32 of the case body 2. The case body 2 is fixed without any problems. For this reason, compared with the method of fixing the holder 10 to the case main body 2 by screwing, it is possible to improve the production efficiency because the screwing process is unnecessary.

  Thus, according to the cartridge case and the tape cartridge 1, the security tag 9 is attached to the holder 10 and disposed in the partition region 4 of the case body 2, so that the holder 10 is attached to the bottom plate 11 a of the case body 2, The security tag 9 can be fixed to the case body 2 together with the holder 10 by contacting the top plate 12a, the side plates 11d and 12d, and the partition plates 11i and 12i. Therefore, according to the cartridge case and the tape cartridge 1, unlike the conventional fixing method using an adhesive or an adhesive tape, even if the security tag 9 has few flat portions that can be used as an adhesive surface, the security tag 9 Can be securely fixed to the case body 2. Further, according to the cartridge case and the tape cartridge 1, the security tag 9 is fixed using the holder 10 without using an adhesive or an adhesive tape, and therefore the security tag 9 is attached to the case main body due to aged deterioration of the adhesive or the adhesive tape. Unlike the conventional fixing method in which the security tag 9 may be peeled off, the state where the security tag 9 is securely fixed can be maintained for a long period of time. Further, according to the cartridge case and the tape cartridge 1, since a screwing process is not required, it is possible to fix the holder 10 to the case main body 2 by screwing in a short time and easily. As a result, production efficiency can be sufficiently improved.

  Further, according to the cartridge case and the tape cartridge 1, the holder 10 and the security tag 9 are provided by arranging the holder 10 in the partition area A4 in a state of being in contact with the columnar protrusions 31 and 32 of the case body 2. Can be more securely fixed to prevent the security tag 9 from moving.

  Further, according to the cartridge case and the tape cartridge 1, the holder body 51 that is formed in a substantially semi-cylindrical shape and holds the coil portion 9a of the security tag 9 and the lead terminal 44 of the capacitor 9b in the security tag 9 are fitted with one touch. By configuring the holder 10 with the pair of holding portions 52 to hold, the coil portion 9a and the capacitor 9b can be securely and easily attached to the holder 10 in a short time, thereby further improving the production efficiency. However, the security tag 9 can be more reliably fixed.

  Further, according to the cartridge case and the tape cartridge 1, the first holding piece 71 erected on the outer peripheral surface of the holder body 51 so as to protrude from the holder body 51 and the first holding piece 71 are spaced apart from each other by a predetermined interval. The holding portion 52 is configured by including a claw portion 72a standing on the outer peripheral surface of the holder main body 51 and protruding toward the first holding piece 71 and having a second holding piece formed at the tip. In spite of a simple configuration, it is possible to achieve the one-touch fitting of the lead terminal 44 and the reliable holding of the fitted lead terminal 44.

  Further, according to the cartridge case and the tape cartridge 1, the slit 62a is formed in one of the both wall portions 62 of the holder 10, so that the holder main body 51 is elastically deformed when the coil portion 9a is fitted into the holder main body 51. As a result of the opening 51a spreading, the operation of fitting the coil portion 9a into the holder main body 51 can be performed reliably and easily.

  Further, according to the cartridge case and the tape cartridge 1, the holder body 51 is formed by forming the rib 61c protruding inside the holder body 51 on the inner peripheral surface 61b in the vicinity of the opening 51a at the end 61a of the body 61. The movement of the coil portion 9a fitted into the opening portion 51a side can be reliably restricted by the rib 61c. For this reason, falling off of the coil part 9a from the holder main body 51 is prevented, and the coil part 9a can be reliably held.

  In addition, this invention is not limited to said structure. For example, although the above description has been made with respect to the example provided with the security tag 9 having the cylindrical coil portion 9a and the holder 10 to which the security tag 9 can be attached, the plate-shaped security tag having a planar coil and the plate It is also possible to adopt a configuration having a holder to which a security tag can be attached. Further, the holder 10 is brought into contact with the bottom plate 11a, the top plate 12a, the side plates 11d and 12d, the partition plates 11i and 12i, and the columnar protrusions 31 and 32 of the case main body 2 so that the security tag 9 together with the holder 10 As described above, the case body 2 is formed with other plate materials and projections other than the above, and the holder 10 is brought into contact with these other plate materials and projections in addition to the above plates. Thus, the security tag 9 and the holder 10 can be fixed to the case body 2. In this case, it is also possible to form a dedicated protrusion for contacting the holder 10 in which the screw fixing hole 31a and the reference hole 32a are not formed on at least one of the bottom plate 11a and the top plate 12a. Furthermore, a configuration in which the holder 10 is not in contact with the columnar protrusions 31 and 32, that is, a configuration in which the holder 10 is in contact with only the respective plates described above can be employed. In addition, the example applied to the one-reel type one tape cartridge 1 including the single tape reel 3 has been described above, but it is needless to say that the present invention can be applied to a two-reel type tape cartridge.
