Description

The present invention relates to an information storage device to be discarded and a hydraulic destruction device that prevents information leakage by destroying an information recording medium, and in particular, destroys an information storage device such as an SSD (Solid State Drive) device to store information. The present invention relates to a hydraulic breaker that makes access impossible.

  Since information storage devices such as SSD devices and HDD (Hard Disk Drive) devices can contain a large amount of confidential information, the leakage of stored information becomes a problem from the viewpoint of security when discarding such information storage devices. It has become.

  When discarding such an information storage device, it is basic to delete the stored information. However, deleting the stored information is not only time consuming and time consuming, but is also stored so that it is substantially unreadable. It is not always easy to completely erase information.

  In addition, it is not easy to confirm that the retained information has been completely erased. Further, when the erasing process is performed by an electrical method or a magnetic method, the retained information is completely erased only by the appearance of the information storage device. Since it is not possible to determine whether or not the processing has been performed, care must be taken in managing the processing history.

  On the other hand, a plurality of hydraulic cylinder mechanisms provided with a crushing tool (conical pressing portion) at the tip of the piston rod are driven by a hydraulic pump, and an information storage device such as an HDD device is controlled regardless of its internal structure (a platter to be destroyed). Etc., no matter how the actuator is mechanically strong and difficult to break down, no matter how it is placed in the device, a hydraulic breaker is proposed that reliably breaks and makes it impossible to read the stored information (Patent Document) 1 and 2) have already been established in the market as a means for preventing information leakage when an information storage device such as an HDD device is discarded.

In addition, since such a conventional hydraulic destruction device mainly includes an HDD device, it is provided with 2 to 4 hydraulic cylinder mechanisms, and an information recording medium (a disc such as a CD-R) other than the HDD device. The medium) can also be destroyed to the extent that access to the stored information is impossible.

  In recent years, SSD devices have become widespread as information storage devices that can be replaced with HDD devices, and in particular, portable personal computers such as notebook personal computers use SSD devices instead of HDD devices. .

  In such an SSD device, for example, a 2.5-inch SSD device, the housing shape and external dimensions are substantially the same as the 2.5-inch HDD device to be replaced. In addition, a wiring board on which a plurality of nonvolatile semiconductor memory chips and other semiconductor chips such as a controller are mounted as information recording media is accommodated in platters and actuators of HDD devices.

  However, in the case of a 2.5-inch HDD device, the center position and diameter of one or a plurality of platters that are coaxially stacked as an information recording medium arranged in the housing depends on the manufacturer and the storage capacity. It is almost the same for each model, but in the case of a 2.5 inch SSD device, the number and arrangement of the semiconductor memory chips mounted on the wiring board are arbitrary for each model depending on the storage capacity of the semiconductor memory chip alone. In many cases, it differs depending on the storage capacity of the manufacturer or the SSD device.

  In order to destroy the SSD device so that it is impossible to access the stored information, it is necessary to destroy each of the plurality of semiconductor memory chips mounted on the wiring board. For example, even if four crushing tools are provided for the platter of the HDD device, there is a problem that it is not possible to reliably destroy all of the semiconductor memory chips mounted in an arbitrary number and arrangement on the wiring board. is there.

An object of the present invention is to provide a hydraulic destruction device that destroys an information storage device such as an SSD device and makes it impossible to access stored information.

The receiving groove is formed so as to be opposed to a plurality of rows in which the hydraulic cylinder mechanisms are arranged.

  The tray forms a plurality of receiving grooves that have a depth of 1/3 or more and 2/3 or less of the height of the object to be destroyed. The receiving groove is formed by fixing a plurality of rod-shaped bodies arranged in parallel, and the rod-shaped body has a circular or rectangular cross section.

  The hydraulic mechanism unit has hydraulic cylinder mechanisms arranged at equal intervals in all of the plurality of rows, and the to-be-destructed object storage unit has a predetermined distance equal to or less than the equal interval in a direction parallel to the plurality of rows. A movable tray moving mechanism is provided.

The plurality of receiving grooves for avoiding contact with the sharpened portion at the forward limit of the piston rod are formed relative to the plurality of rows in which the hydraulic cylinder mechanism is arranged, so that the sharpened portion of the piston rod is the SSD device. Even if the semiconductor memory chip mounted on the wiring board is not in contact with all of the semiconductor memory chips, by deforming the wiring board so as to be bent along the receiving groove, more semiconductor memory chips are broken and folded so that the retained information Can be made impossible to access.

In addition, the hydraulic cylinder mechanisms are arranged at equal intervals in all of the plurality of rows, and the tray can be moved in a direction parallel to the plurality of rows where the hydraulic cylinder mechanisms are arranged.

The passages 412 and 414 communicate with each other.

  In this embodiment, the communication path 412 is connected to the oil chamber 406 and the communication path 414 is connected to the lower portion of the cylinder 404, but the communication path 412 is connected directly to the communication path 408 and the communication path 414 is connected directly to the communication path 410. It doesn't matter.

  Further, both ends of the communication passages 408, 410, 412, and 414 are sealed with a sealing plug 418, and the communication passage 408 (or the communication passage 412) is connected to the hydraulic hose 36 via the hose connection joint 42, and is connected to the communication hose. The passage 410 (which may be the communication passage 414) is connected to the hydraulic hose 38 via the oil passage 416 and the hose connection joint 44.

[Operation of hydraulic breaker]
Here, the basic procedure of the destruction operation of the SSD device in the hydraulic destruction device 10 is as follows. First, the power switch 18 is operated to turn on the power, and the processing mode is set by the touch panel 22.

  As processing modes, there are a 1-cycle mode in which the hydraulic cylinder mechanism is operated once and a 2-cycle mode in which the position of the tray 60 is moved to operate the hydraulic cylinder mechanism twice. Select the appropriate mode.

  Then, the destruction process is started by opening the door 14 and inserting the tray 60 on which the SSD device 62 is placed from the insertion port 16 and closing the door 14 and pressing the start switch 20. After the destruction process is completed and the touch panel 22 displays that the destruction process is completed, the door 14 is opened and the tray is pulled out to complete a series of destruction operations.

  FIG. 8 shows the operation of the hydraulic breaking device 10 after the tray 60 is accommodated in the destructive object accommodating portion 50, with the cross section taken along the line BB in FIG. 2 extended to the introducing portion 512. (A) is the operation in the first cycle, and FIG. 8 (B) is the operation in the second cycle. Note that the hydraulic mechanism 40 is omitted, and the SSD device 62 that is the destruction target is indicated by a virtual line.

  In FIG. 8A, the tray 60 is pushed in until it comes into contact with the end plate 506 of the to-be-destructed object container 50, and is held by the magnet 514 with the microswitch 518 turned on (see FIG. 3). Further, the door 14 is held at a position where the insertion port 16 is closed by the magnet 516, and the microswitch 520 is in an ON state.

  When the start switch 20 is pressed in this state, the control unit 32 indicates that the trays 60 are normally accommodated because the microswitches 518 and 520 are both on, and the door 14 is also normally closed. The hydraulic cylinder mechanism 400 is operated by the hydraulic pump device 30 to move the piston rod 422 forward and backward, and the SSD device 62 placed on the tray 60 is destroyed.

  When the processing mode is the two-cycle mode, as shown in FIG. 8B, the solenoid 522 is driven to move the tray 60 in the direction of the door 14, and the hydraulic cylinder mechanism 400 is operated again to operate the piston. The rod 422 is advanced and retracted, and the SSD device 62 is further destroyed. At this time, the moving distance S of the tray 60 may be equal to or less than the pitch P of the cylinder 404, but S = P / 2 is desirable.

  In the present embodiment, the movement direction of the tray 60 is the direction of the door 14, that is, the direction opposite to the insertion direction, but is moved in the direction perpendicular to the insertion direction, that is, the direction of the side plate 502 or the side plate 504. In this case, the movement distance may be equal to or less than the distance between the rows of the cylinder mechanisms of a plurality of rows, but 1/2 of the distance between the rows is desirable.

  FIG. 9 is a flowchart showing an outline of the destruction process by the control unit 32, and FIG. 10 is a flowchart showing an outline of the hydraulic process of FIG. 9. After the processing mode is set by the touch panel 22, the door 14 is opened. This is a process flow after the tray 60 on which the SSD device 62 is placed is inserted from the insertion port 16, the door 14 is closed, and the start switch 20 is pressed.

  When the start switch 20 is pressed, the destruction process is started as shown in FIG. 9. First, in step S1, it is confirmed whether or not the door 14 is closed. If the micro switch 520 is on, the door 14 is closed. It is determined that the tray 60 is in the first position (the position where the tray 60 is held by the magnet 514), that is, the tray 60 is securely inserted into the destructive object storage unit 50. If the micro switch 518 is in the on state, it is determined that the tray 60 is in the first position, “processing start” is displayed on the touch panel 22 in step S4, and the hydraulic treatment shown in FIG. 10 is performed in step S6. Run.

  If it is determined in step S1 that the door 14 is not closed, a warning “door not closed” is displayed on the touch panel 22 in step S3. If it is determined in step S2 that the tray 60 is not in the first position, step S5 is performed. The warning message “Tray insertion failure” is displayed and the destruction process is terminated.

  In the hydraulic processing in step S6, as shown in FIG. 10, first, the electric motor 304 of the hydraulic pump device 30 is driven in step S21. In the initial state of the hydraulic processing, the hydraulic circuit is set to apply hydraulic pressure to the pushing side of the piston portion 424. Therefore, the hydraulic pump device 30 supplies the hydraulic oil to the oil chamber 406 via the hydraulic hose 36 and piston. The rod 422 is advanced.

  In step S22, it is monitored whether or not the hydraulic circuit (pushing side of the piston portion 424) has reached a predetermined pressure. If it is determined that the predetermined pressure has been reached by operating the pressure switch 310, the electric motor 304 is stopped in step S23. Thus, the supply of hydraulic oil to the oil chamber 406 is shut off, and the forward movement of the piston rod 422 is braked. Here, the pressure switch 310 is activated when the advance of all the piston rods 422 is restricted and the push-side hydraulic circuit reaches a predetermined pressure.

  Next, in step S24, the solenoid valve 306 of the hydraulic pump device 30 is operated, and the hydraulic circuit is switched to supply hydraulic oil to the lower side of the cylinder 404 via the pull side of the piston portion 424, that is, the hydraulic hose 38. When the electric motor 304 is driven in step S25, the hydraulic pump device 30 applies hydraulic pressure so as to push the piston portion 424 back upward, and the piston rod 422 is moved backward.

  In step S26, it is monitored whether or not the hydraulic circuit (pull side of the piston portion 424) has reached a predetermined pressure. If it is determined that the predetermined pressure has been reached by operating the pressure switch 312, the electric motor 304 is stopped in step S27. Thus, the supply of hydraulic oil to the lower portion of the cylinder 404 is shut off, and the backward movement of the piston rod 422 is braked. Here, the pressure switch 312 operates when all the piston rods 422 reach the retreat limit, and the pulling hydraulic circuit reaches a predetermined pressure.

  When the piston rod 422 stops, the electromagnetic valve 306 of the hydraulic pump device 30 is actuated in step S28, and the hydraulic circuit is switched to the push side of the piston portion 424, that is, the initial position for supplying hydraulic oil to the oil chamber 406, and the hydraulic processing Ends.

  When the hydraulic processing is completed, the process proceeds to step S7 in FIG. 9 to confirm the setting of the processing mode. If the setting is one cycle mode, the process proceeds to step S11, the processing end is displayed on the touch panel 22 and the destruction process is terminated. To do. If the two-cycle mode is set in step S7, the solenoid 522 is driven in step S8, and the tray 60 is moved against the holding of the magnet 514.

  In step S9, it is confirmed whether or not the tray 60 is in the second position (position approaching the direction of the door 14 by the moving distance S from the first position). When a predetermined time has elapsed after the solenoid 522 is driven, the micro switch If 518 is off, it is determined that the tray 60 is in the second position, and the hydraulic treatment shown in FIG. 10 is executed again in step S10. When the hydraulic treatment is finished, the process end is displayed on the touch panel 22 in step S11, and the destruction process is finished.
