Description

  The present invention relates to a storage medium destruction device for destroying a hard disk drive, a memory, various disks, and other storage media.

  Personal computers, mobile phones, PDAs, and other information devices often need to migrate to new models due to their short life cycle. In such a case, from the viewpoint of preventing information leakage, it is preferable not only to erase information stored in the built-in storage medium but also to physically destroy the storage medium. For this reason, various destructive device means for destroying the storage medium have been proposed in the past (see, for example, Patent Document 1). The storage medium is held and fixed together with the case by the holding means, and toward the fixed storage medium. In many cases, the pin was moved up and penetrated into the storage medium.

Registered Utility Model No. 3108834 Specification

  However, since the case of the storage medium is often formed of a hard material, when the destruction of the storage medium is performed for each case by a conventional destruction device, the pin is bitten into the storage medium and the pin is removed from the storage medium. It may become difficult to come off. Therefore, in order to remove the pin, it is necessary to perform it manually, which not only takes time, but also requires a large amount of labor for removal, resulting in poor work efficiency.

  In addition, the conventional breaking device has a configuration in which the pin is attached to the drive device side and the pin is moved. However, in this case, the fixing strength of the pin is weakened, the pin falls down, and the breaking operation may fail. . Furthermore, depending on the size of the storage medium, it is effective in terms of work efficiency to provide a plurality of through holes at the same time. However, when the pin fixing strength is weak, the plurality of pins come into contact with the storage medium. In some cases, the storage media may fall down in a direction away from each other, which is not suitable for the destruction work when the storage medium is large.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a storage medium destruction device that can destroy a storage medium easily and reliably in a short time and can easily take out and discard the storage medium even after destruction. Furthermore, an object of the present invention is to reliably destroy a storage medium in a short time with a small force even if the storage medium has high rigidity or a complicated internal structure, and can easily be stored after the destruction. It is an object of the present invention to provide a storage medium destruction apparatus that can take out and discard the storage medium.

  In the storage medium destruction apparatus of the present invention, the second urging unit has an elastic member that applies an elastic force in a direction away from the piercing member to the holding unit urged by the first urging unit. It is characterized by that.

  In the storage medium destruction apparatus according to the present invention, the storage medium destruction device includes a moving unit that moves the holding unit biased by the first biasing unit in a direction away from the punching member.

  In the storage medium destruction apparatus of the present invention, the perforating member is one or more punches that are detachably fixed on the upper part of the apparatus main body.

  In the storage medium destruction apparatus of the present invention, the first biasing means is a hydraulic jack.

  According to the present invention, the operation of removing the storage medium after destruction can be easily performed, and the biting of the piercing member into the storage medium can be quickly released by the second urging means. Therefore, it is possible to provide a storage medium destruction apparatus that can not only reliably destroy a storage medium in a short time with a small force but also can easily take out and discard the storage medium even after destruction. Therefore, the storage medium destruction apparatus of the present invention is particularly suitable for the destruction process of a storage medium having high rigidity or a complicated internal structure, and can reliably destroy the storage medium in a short time with a small force. The storage medium can be easily taken out and discarded after destruction. In addition, since the entire apparatus has a simple configuration, an increase in manufacturing cost can be prevented.

  Hereinafter, a storage medium destruction apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a partially broken external configuration of a storage medium destruction apparatus according to the present invention, a partially enlarged view of a state in which a moving means is operated, and FIG. 2 is a storage medium according to the present invention. FIG. 3 is a front view of the destruction apparatus in a state where the first urging means is not urged, and FIG. 3 is a plan view showing the configuration of the upper part of the storage medium destruction apparatus according to the present invention.

  As shown in FIG. 1 or FIG. 2, a storage medium destruction apparatus 10 according to this embodiment includes a holding means 20, a punching member 30, and a hydraulic jack arranged in an apparatus main body 11 formed in a substantially box shape. 40 (first urging means), moving means 50 (second urging means), and elastic member 60 (second urging means). The storage medium destruction apparatus 10 according to the present embodiment urges the storage medium 70 held by the holding means 20 to the piercing member 30 using the hydraulic jack 40 (first urging means), thereby the storage medium 70. The piercing member 30 is inserted into the hole to form a hole, thereby destroying the storage medium 70.

  Examples of the storage medium 70 to be destroyed by the storage medium destruction device 10 according to this embodiment include a hard disk drive (HDD), a memory (storage device), a disk (for example, a CD-R, a DVD, a Blu-ray disc (registered). (Trademark), MO, floppy disk (registered trademark)), magnetic tape (for example, DAT (Digital Audio Tape)), and the like. In particular, the storage medium destruction apparatus 10 according to the present embodiment is suitable for a hard disk drive apparatus having a high case rigidity and a complicated internal structure. Below, the detailed structure of each member of the storage medium destruction apparatus 10 is demonstrated.

  The piercing member 30 includes, for example, three punches 31, 32, and 33. These punches 31, 32, 33 are detachably fixed to the top plate 11 a (see FIG. 3) of the device main body 11 of the storage medium destruction device 10, with the distal ends thereof facing downward. It is a metal member whose outer diameter becomes smaller toward the tip. As shown in FIG. 3, it is preferable that the positions of the punches 31, 32, and 33 are separated from each other so that, for example, each is located at the apex of an isosceles triangle in the top view. The punch 31, 32, 33 may be fixed to the apparatus main body 11 of the storage medium destruction apparatus 10 with a strength that can withstand the urging force of the hydraulic jack 40 (first urging means) when the storage medium 60 is drilled. For example, it is particularly preferable that the distal end is inserted from the outside of the top surface 11a of the apparatus main body 11 toward the inside of the apparatus main body 11, and the base end is locked by the outer surface of the top surface 11a.

  By configuring the perforating member 30 as described above, when the punches 31, 32, and 33 are worn or damaged, it is possible to perform the replacement work easily and quickly. Further, the three punches 31, 32, 33 are not interlocked by the hydraulic jack 40 as the first urging means, but are configured to be fixed to the apparatus main body 11 itself. Can be firmly fixed, and when the storage medium 70 is perforated, no wobbling or falling away from each other, and even the highly rigid storage medium 70 can be reliably destroyed. Can do. The punches 31, 32, and 33 are formed to have a length suitable for destruction by a material (for example, steel) according to the material of the destruction target. The shape, number and arrangement of the piercing members 30 can be arbitrarily set as long as a hole can be formed in the storage medium 70. The shape of the piercing member 30 is, for example, a claw shape or a column shape. You can also. Further, the hole formed in the storage medium 70 by the piercing member 30 is not limited to a through-hole that completely penetrates the storage medium 70, and serves as a dent for preventing the storage medium 70 from functioning again. It may be a hole.

  As an example, the holding unit 20 includes a mounting table 21 on which the storage medium 70 is mounted, and a top surface 22 that is opposed to the upper surface side of the mounting table 21, and the mounting table 21 and the top surface 22 together. The sliding movement is possible in the vertical direction on the inner surface of the apparatus main body 11. The loading table 21 and the top surface 22 may be integrated or separate. The top surface 22 is formed with insertion holes 22a, 22b, and 22c (see FIG. 1) into which the punches 31, 32, and 33 can be inserted, respectively. When the storage medium 70 is punched, the punches 31, 32, and 33 are Through the insertion holes 22a, 22b, and 22c of the top surface 22, the storage medium 70 loaded on the loading table 21 is reached and a hole can be formed. In other words, the punches 31, 32, and 33 (perforated members) arranged to face the storage medium 70 stacked (held) on the mounting table 21 (holding means) are inserted into the insertion holes 22 a of the top surface 22. , 22b and 22c, holes can be formed in the storage medium 70. It is preferable that the gap between the loading table 21 and the top surface 22 is set to a short length in consideration of the size of the storage medium 70 to be destroyed and the length that can be slid by the urging of the hydraulic jack 40. is there.

  In the present embodiment, the holding means 20 is constituted by the mounting table 21 and the top surface 22, and the top surface 22 is formed with insertion holes 22 a, 22 b, 22 c into which the punches 31, 32, 33 can be inserted. However, the holding means of the present invention is not limited to such a configuration. For example, the storage medium 70 may be configured by only the mounting table 21 on which the storage medium 70 can be stacked. In this case, a lower end of a shaft portion 50b of a moving unit 50 (toggle clamp) described later directly contacts the storage medium 70. What should I do? Alternatively, an insertion hole 22d is formed in a portion indicated by an imaginary line in FIG. 1, and a lower end of a shaft portion 50b of a moving means 50 (toggle clamp) described later directly contacts the storage medium 70 through the insertion hole 22d. You may do it.

  The elastic member 60 as the second urging means is applied to the holding means 20 urged by the hydraulic jack 40 (first urging means) as the first urging means in order to hold the holding means 20 in the initial position. On the other hand, an elastic force is applied in a direction away from the punches 31, 32, 33 (piercing member). Here, the initial position of the holding means 20 is a position where the perforating member 30 (punches 31, 32, 33) does not contact the storage medium 70 held by the holding means 20 (see FIGS. 1 and 2). . More specifically, the elastic member 60 includes, for example, two tension coil springs 60L and 60R (elastic members) that hold the mounting table 21 in an initial position by an elastic force. One end of each of the tension coil springs 60L and 60R is: The other end is locked to the holding means 20 (in particular, the lower surface of the stacking portion 21) (see FIG. 2). In this configuration, the loading table 21 is urged downward by the elastic force of the tension coil springs 60L and 60R, and the holding means 20 as a whole is also urged downward.

  By configuring the elastic member 60 as the second urging unit as described above, when the storage medium 70 held by the holding unit 20 is raised by the urging of the hydraulic jack 40 (first urging unit), An elastic force is applied in a direction opposite to the biasing of the hydraulic jack 40 (first biasing means), and as a result, the punching operation (breaking operation) of the punches 31, 32, 33 (piercing member) with respect to the storage medium 70 is performed. It is possible to prevent abruptly being performed, and it is possible to perform work carefully while confirming and adjusting the push-in position. In particular, when the piercing member is composed of a plurality of punches as in the present embodiment, when the punches 31, 32, and 33 (piercing members) are inserted into the storage medium 70 to form holes, the hydraulic jack 40 is used. Even if the urging by the (first urging means) is released, there may occur a situation in which the punches 31, 32, 33 (perforated member) remain in the storage medium 70 and cannot be removed. The punch 31, 32, 33 (perforated member) can be quickly released from the storage medium 70 by the elastic force of the elastic member 60 as the biasing means, and the processing after the break can be performed smoothly.

  If the holding means 20 can be held at the initial position by elastic force, an elastic member (for example, a leaf spring or rubber) can be used instead of the tension coil springs 60L and 60R. Further, the number and arrangement of the tension springs can be arbitrarily set as long as the holding means 20 is held in a balanced manner at the initial position, and the number may be one or three or more.

  The first urging means can urge the holding means 20 from the initial position until the piercing member 30 reaches a position where a hole can be formed in the storage medium 70. For example, the first urging means is constituted by a hydraulic jack 40. Is preferred. The hydraulic jack 40 includes a jack body 41 and a lever 42. The lever 42 can be operated in the vertical direction while being inserted into the support portion 42a. For example, the hydraulic pressure in the jack body 41 can be increased by pushing down, and the hydraulic pressure can be further increased by repeatedly pushing down. Can be increased. In contrast, the increased hydraulic pressure can be reduced by opening a release valve (not shown). A shaft 41 a (see FIG. 4) that can be raised and lowered according to the hydraulic pressure in the jack body 41 is accommodated in the jack body 41.

  The hydraulic pressure inside the jack body 41 is increased by the operation of the lever 42, and this increased hydraulic pressure raises the shaft 41a and urges the holding means 20 (stacking portion 21) upward (in a direction approaching the punching member). Become a force. On the other hand, when the release valve is opened to lower the hydraulic pressure, the urging force is released and the shaft 41a is lowered. The upper end portion of the shaft 41a is in contact with or fixed to the lower surface of the holding means 20 (loading table 21). In the initial state in which the release valve is opened and the hydraulic pressure is lowered most, the holding means 20 (loading base 21) is urged downward by the tension coil springs 60L and 60R, while from the hydraulic jack 40 as the first urging means. Does not receive upward bias. At this time, since the loading table 21 is sufficiently separated from the tips of the punches 31, 32, 33, the storage medium 70 is loaded on the loading table 21 without touching the tips of the punches 31, 32, 33 in this state. can do.

  As the first urging means, any means other than a hydraulic jack (for example, a screw type) may be used as long as it can raise the holding means 20 or the storage medium 70 against the elastic force of the tension coil springs 60L and 60R. Can be used.

  The moving means 50 as the second urging means uses the holding means 20 urged by the hydraulic jack 40 as the first urging means to move the holding means 20 to the initial position. It moves in the direction away from 31, 32, 33. As shown in FIGS. 1 to 3, the moving unit 50 preferably uses, for example, a toggle clamp including an operation unit 50 a (handle), a shaft unit 50 b (rod), and a base unit 50 c. The base portion 50c is attached to the top plate 11a of the apparatus main body 11 (in this embodiment, the fixed base 11b erected from the top plate 11a), and in accordance with the turning operation of the operation portion 50a, the shaft portion A toggle mechanism that slidably supports 50b is provided, and one end (upper end) of the shaft portion 50b is pushed and pulled. The top plate 11a of the apparatus main body 11 is formed with a penetrating portion (not shown) at a substantially central portion of the arrangement position of the punches 31 and 33, and the other end (lower end) of the shaft portion 50b is the apparatus main body 11. The top plate 11a is inserted into the inside of the apparatus main body 11 through the penetrating portion so as to penetrate in the vertical direction (the vertical direction in FIG. 1 or FIG. 2, the direction perpendicular to the paper surface in FIG. 3). Therefore, the shaft part 50b can be moved up and down by rotating the operation part 50a up and down. The lower end of the shaft portion 50b is located above the tips (lower ends) of the punches 31, 32, 33 when the operation portion 50a is in the initial state (see the entire perspective view in FIG. 1), while the operation portion 50a Is set to be located at the same position as or below the front ends (lower ends) of the punches 31, 32, 33.

  By configuring the moving means 50 as the second urging means as described above, in the state where the holding means 20 is in the position when it is moved upward by being urged by the hydraulic jack 40, the operating portion 50a. Is rotated downward from the initial state to lower the shaft portion 50b (see a partially enlarged view in FIG. 1), the lower end of the shaft portion 50b comes into contact with the holding means 20 (the top surface 22), and the shaft portion 50b itself is held. The means 20 (top surface 22) can be urged downward. Since the moving means 50 as the second urging means is configured as described above, after the punches 31, 32, 33 (piercing members) are inserted into the storage medium 70 to form holes, the hydraulic jack In the present invention, when the urging by the 40 (first urging means) is released, the situation where the punches 31, 32, 33 (perforating member) cannot be removed while being bitten into the storage medium 70 occurs. The holding means 20 is moved in a direction away from the punches 31, 32, 33 (piercing member) by the biasing by the moving means 50 as the biasing means, and the punches 31, 32, 33 (piercing member) are transferred to the storage medium 70. It becomes possible to release the bite promptly. In particular, as in the present embodiment, by providing not only the elastic member 60 but also the moving member 50 as the second urging member, the punches 31, 32, 33 (perforated member) may be provided by the elastic force of the elastic member 60. Even if it is not possible to release the biting into the storage medium 70, it is preferable that the biting can be surely released by the urging force of the moving means 50, and the processing after destruction can be performed smoothly.

  In the apparatus main body 11 of the storage medium destruction apparatus 10, for example, a front plate of a door structure (not shown in the figure) is configured such that a portion to be perforated by the perforating member 30 (punches 31, 32, 33) is blocked from the outside. May be attached. It is preferable that the front plate is formed of a transparent member at least at a site where the drilling operation state can be confirmed.

  Next, the flow of the destruction process of the storage medium 70 using the storage medium destruction apparatus 10 will be described with reference to FIGS. Here, FIG. 4 is a plan view showing a state in which the storage medium destruction apparatus according to the present invention is urged by the first urging means.

  First, the storage medium 70 is placed on the loading table 21 in the state shown in FIG. At this time, the hydraulic pressure of the hydraulic jack 40 is equal to the atmospheric pressure (non-pressurized state), and the urging force to the holding means 20 by the hydraulic jack 40 is not working. Therefore, with respect to the storage medium destruction device 10 with the holding means 20 in the initial position, the storage medium 70 is slid into the gap between the loading table 21 and the top surface 22 while the storage medium 70 is punched 31. , 32, 33 without contacting the mounting table 21.

  Next, as shown in FIG. 4, when the hydraulic pressure in the jack body 41 is increased by performing an operation of pushing the lever 42 downward, the shaft 41a is raised. The holding means 20 is held at the initial position by the elastic force of the tension coil springs 60L and 60R. However, the force that urges the holding means 20 upward generated by the hydraulic jack 40 when the lever 42 is pushed down is greater than the elastic force. The holding means 20 is further urged upward, and accordingly, the holding means 20 slides upward on the inner surface of the apparatus main body 11, and the storage medium 70 held by the holding means 20 is moved to the punch 31, Move upward toward 32,33. The amount of movement of the holding means 20 and the storage medium 70 is adjusted by the amount of depression of the lever 42 and the number of depressions.

  When the holding means 20 is further moved upward by the operation of the lever 42, the holding means 20 and the storage medium 70 are further moved upward, and the storage medium 70 contacts the tips of the punches 31, 32, 33. In this state, the punch 31, 32, 33 receives a force that prevents upward movement, but when the lever 42 is further operated, the punch 31, 32, 33 is inserted into the storage medium 70 to form a hole. And the destruction of the storage medium 70 is performed.

  The storage medium 70 is taken out after the destruction is performed as follows. First, the hydraulic pressure in the jack body 41 is lowered by operating a release valve (not shown) of the hydraulic jack 40. Thereby, the axis | shaft 41a of the jack main body 41 descend | falls, and the upward force with respect to the holding means 20 by the hydraulic jack 40 is cancelled | released. When the urging force from the hydraulic jack 40 is released, the holding means 20 is urged downward by the elastic force of the tension coil springs 60L and 60R, and accordingly, the holding means 20 is lowered on the inner surface of the apparatus main body 11. It slides in the direction (direction away from the punches 31, 32, 33), and the punches 31, 32, 33 inserted into the storage medium 70 are pulled out from the storage medium 70.

  Here, if the punches 31, 32, 33 are not removed from the storage medium 70 by only the elastic force of the tension coil springs 60 </ b> L, 60 </ b> R due to the rigidity of the storage medium 70, the internal structure, and other factors, the moving means 50 By rotating the operation portion 50a downward from the initial state, the shaft portion 50b is lowered (see a partially enlarged view in FIG. 1), and the lower end of the shaft portion 50b is brought into contact with the holding means 20 (top surface 22). The holding part 20 (top surface 22) is urged downward by the shaft part 50b itself and is forced to move manually. In this way, the punches 31, 32, 33 can be reliably removed from the storage medium 70.

  In the holding means 20 returned to the initial position by the above operation, the storage medium 70 is slid into the punches 31, 32, 33 while sliding the storage medium 70 substantially in parallel from the gap between the loading table 21 and the top surface 22. It can be taken out without contact, and the destruction work by the storage medium destruction apparatus 10 can be completed.

With the configuration as described above, the storage medium destruction apparatus 10 according to the above embodiment has the following effects.
(1) By using the hydraulic jack 40, the storage medium 70 is raised toward the punches 31, 32, 33 fixed to the apparatus body 11, and the punches 31, 32, 33 are inserted into the storage medium 70, It is possible to provide a small storage medium destruction apparatus that can perform destruction processing with a small force. Further, since the entire apparatus has a simple configuration, an increase in manufacturing cost can be prevented.

  (2) Since the punches 31, 32, and 33 are fixed, the storage medium 70 is not staggered or fallen away from each other when the storage medium 70 is perforated. Destructive work can be performed reliably.

  (3) It is possible to quickly release the punch 31, 32, 33 (perforated member) from biting into the storage medium 70 by the elastic force of the elastic member 60 (tensile coil springs 60 </ b> L, 60 </ b> R), and smooth processing after destruction. Can be done.

  (4) By providing the moving means 50 in addition to the elastic member 60 (the tension coil springs 60L and 60R), the biting can be reliably released by the urging force of the moving means 50, and the processing after the break can be performed smoothly. it can.

  A modification will be described below. In the above embodiment, as the second urging means, the structure having both the elastic member 60 and the moving means 50 has been described. However, the second urging means is not necessarily limited to having both, and only one of them is provided. You may comprise as a storage medium destruction apparatus with which it is equipped.

  In the above embodiment, the moving means 50 as the second urging means has been described as being configured by a toggle clamp. However, the storage medium 70 held by the holding means is inserted into the punches 31, 32, 33 (piercing member). If it can be moved in a direction away from the above, it is possible to use means other than the above-described configuration, and another modification will be described with reference to FIG. FIG. 5 is a perspective view showing an external configuration of a storage medium destruction apparatus (modification) according to the present invention. In addition, about what has the function thru | or structure which is common in the storage medium destruction apparatus 10 which concerns on the said embodiment, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

  The moving means 150 as the second urging means uses the holding means 20 urged by the hydraulic jack 40 as the first urging means to move the holding means 20 to the initial position. It moves in the direction away from 31, 32, 33. As illustrated in FIG. 5, the moving unit 150 includes, for example, a compression coil spring 151 and a rotation lever 152. The rotary lever 152 includes an operation part 152a (handle) and a shaft part 152b, and the operation part 152a is fixed to one end (upper end) of the shaft part 152b. The top plate 11a of the apparatus main body 11 is formed with a penetrating portion (not shown in the drawing) at a substantially central portion of the position where the punches 31, 32, 33 are arranged, and the other end (lower end) of the shaft portion 152b is The top plate 11a of the main body 11 is penetrated in the vertical direction (vertical direction in FIG. 5) to reach the inside of the apparatus main body 11 through the penetrating portion, and a screw groove formed on the outer periphery of the shaft portion 152b It arrange | positions so that it may mesh with the screw groove formed in the inner periphery of the penetration part of the board 11a. As a result, the shaft portion 152b can be moved up and down according to the screw groove by gripping and rotating the operation portion 152a (clockwise or counterclockwise). A shaft portion 152 b of the rotation lever 152 is inserted in the compression coil spring 151. The upper end of the compression coil spring 151 is locked to the shaft portion 152b of the rotation lever 152 and / or the inner surface of the top plate 11a. On the other hand, the lower end of the compression coil spring 151 is positioned below the lower end of the shaft portion 152b in the natural state. Further, the lower end of the compression coil spring 51 is positioned below the tips (lower ends) of the punches 31, 32, 33 and is in contact with the holding means 20 (top surface 22).

  By configuring the moving means 150 as the second urging means as described above, the rotating lever 152 is in a state where the holding means 20 is in the position when it is moved upward by being urged by the hydraulic jack 40. When the operation portion 152a is operated and the shaft portion 152b is lowered, the compression coil spring 151 locked to the shaft portion 152b is compressed, and an elastic force is applied to urge the holding means 20 (top surface 22) downward.
