FIG. 1 is a front view of a recording medium destruction apparatus 100 embodying the present invention.
As shown in FIG. 1, the recording medium destroying device 100 includes a main body device 51 and a monitoring device 50. That is, the main unit 51 includes a fixed base 20 for fixing the motor 3, the hard disk fixed base 5 and the like, and the monitoring device 50 includes the video camera 10 and the like as will be described later.

  The motor 3 is fixed to the main body device 51, and the motor 3 is provided with a speed reducer 2. The motor 3 supports a drive unit 4 in which a plurality of downward pins 1 are fixed to the lower surface via a speed reducer 2. The drive unit 4 can be reciprocated in the vertical direction by rotating the motor 3 forward or backward. That is, the drive unit 4 reciprocates linearly up and down without rotating.

  A hard disk fixing base 5 is installed below the drive unit 4. The hard disk fixing base 5 is provided with a guide member 6 for arranging the hard disk 15 at a predetermined position. The hard disk 15 guided by the guide member 6 is disposed on the hard disk fixing base 5 so as not to move in the horizontal direction so that at least one pin 1 comes directly above the data recording portion.

  On the hard disk fixing base 5, a push button type switch 7 is provided. When the hard disk 15 is arranged on the hard disk fixing base 5, the switch 7 is pushed down on the lower surface of the hard disk 15 to detect that the hard disk 15 is arranged on the hard disk fixing base 5, and this detection signal is not shown. It has the function to transmit to the monitoring apparatus 50 mentioned later via a signal wire | line.

  In the recording medium destruction apparatus 100 of this embodiment, when a work start switch (not shown) is turned on, the motor 3 rotates forward and the drive unit 4 is lowered. The pin 1 of the drive unit 4 presses and deforms the hard disk 15, and the pin 1 penetrates the recording part of the hard disk 15. After the hard disk 15 is destroyed in this way, the motor 3 rotates in the reverse direction, and the drive unit 4 moves up to return to the standby position.

  The monitoring device 50 includes a video camera 10 and a controller 21. The controller 21 has a CPU 8 and a memory 9. The controller 21 and the video camera 10 are connected by a signal line 11. The controller 21 can operate the video camera 10 via the signal line 11. Further, the video taken by the video camera 10 can be recorded in the memory 9 of the controller 21 via the signal line 11.

  The controller 21 is connected to the switch 7 by a signal line (not shown). The switch 7 detects that the hard disk 15 is arranged on the hard disk fixing base 5 and transmits a detection signal to the controller 21. The controller 21 to which the detection signal is input transmits a command signal for starting shooting to the video camera 10.

  When receiving a shooting start command signal from the controller 21, the video camera 10 starts shooting of the hard disk 15 disposed on the hard disk fixing base 5, and ends shooting when receiving a shooting end command signal. The captured video data is transmitted to the memory 9 of the controller 21 via the signal line 11 and recorded.

  The controller 21 to which the hard disk 15 is arranged on the hard disk fixing base 5 and the detection signal is input from the switch 7 issues a code number and associates the code number with the date and time (including time) when the detection signal is received. The data is recorded in the memory 9 as data (for example, data having a versatile format such as a CSV text data format).

  That is, this code number is unique to the hard disk 15 on the hard disk fixing base 5 to be destroyed, and the memory 9 records when the hard disk 15 is destroyed together with video data.

  Further, the serial number of the recording medium destruction apparatus 100 itself may be recorded in the memory 9 at the same time. By doing so, it is possible to prove when and by which destruction device the hard disk 15 was destroyed, and the owner of the hard disk 15 can safely destroy the hard disk 15.

  In the above example, the example of destroying the hard disk 15 has been shown. However, regardless of the type of the recording medium to be destroyed, the video data, the date and time, and the code number assigned to the recording medium are recorded. 21 memory 9 can be recorded.

  In the above example, video data is recorded in the memory 9. However, a still image camera such as a digital camera can be used instead of the video camera 10. In this case, it is preferable that there are a plurality of still images, and at least one of them is recorded in the memory 9 as captured image data of a state in which the recording medium is destroyed. The same applies to a second embodiment to be described later.

  Furthermore, in the above-described example, the example of the recording medium destruction device 100 that drives and drives the drive unit 4 with the motor 3 and the speed reducer 2 to pressurize and destroy the hard disk 15 is shown. Even if the drive source of the unit 4 is driven by hydraulic pressure, water pressure or pneumatic pressure, the monitoring device 50 can monitor the destruction status of the hard disk 15 without any trouble.

In the above-described embodiment, an example in which the monitoring video camera 10 or the digital camera is provided at a position different from the fixing base 20 or the like that fixes the motor 3 is shown. That is, in the above-described embodiment, the monitoring device 50 is provided separately, and the video camera 10 or the like is provided in the monitoring device 50. The video camera 10 used in the previous embodiment exclusively shoots the destruction process of the hard disk 15, but may shoot other images. For example, a turning function may be given to the video camera 10 and the main body device 51 of the recording medium destruction device 100 may be photographed. That is, a still image or a moving image for specifying the recording medium destruction device 100 itself may be taken and recorded. Also, the operator's face and surroundings may be photographed.
Further, the video camera 10 or the like may be provided integrally with the fixed base 20 or the like.

  Hereinafter, an embodiment to which a configuration for photographing an operator's face and the like is added will be described. In the following description, members having the same functions and effects as those of the previous embodiment are denoted by the same reference numerals as those of the previous embodiment, and detailed description thereof is omitted.

The pin 1 is pierced into the hard disk 15 and the hard disk 15 is destroyed.

In the present embodiment, a video camera 37 for photographing an object to be destroyed is installed in the processing chamber 35 in the case 32 as shown in FIG.
The video camera 37 for photographing the object to be destroyed is installed at a position and an attachment angle at which the hard disk fixing base 5 can be photographed. More preferably, the video camera 37 for photographing an object to be destroyed is installed at a position and an attachment angle at which the upper surface side of the hard disk 15 to be destroyed can be photographed. That is, the hard disk 15 is generally covered with a metal or resin case, and has a seal or print surface on one side, and the manufacturer and serial number are written on the seal. For this reason, by installing the video camera 37 for photographing the object to be destroyed at a position where the upper surface side of the hard disk 15 to be destroyed can be photographed, the serial number of the hard disk 15 can be photographed, and the destroyed recording medium Information of a still image or a moving image for specifying the image can be obtained.

The personal computer 103 controls the video camera 34 for shooting an operator, the video camera 37 for shooting an object to be destroyed, and a printer. Furthermore, the personal computer 103 also functions as a bibliographic information recording unit. Bibliographic information may be manually input using the keyboard of the personal computer 103, or information may be read from a predetermined memory and recorded.
Examples of bibliographic information include the following.

(5) Information for identifying the recording medium destruction device itself
(6) Information to identify the reason for destroying the recording medium
(7) Information for identifying the original owner of the destroyed recording medium
(8) Information to identify the person who requested the destruction of the recording medium

  Here, the “information specifying the location where the recording medium destruction device is installed” is, for example, an address where the recording medium destruction device 101 of this embodiment is installed. Further, when a business that destroys a recording medium has a plurality of business establishments and each business establishment has an abbreviation such as “Kobe Factory” or “Amagasaki Factory”, these abbreviations may be recorded. The code number of each office may be recorded.

  The “information specifying when the recording medium is destroyed” is the work date and time, for example, “May 12, 2004, 3:00 pm” is recorded.

  “Information for identifying the person who operated the recording medium destruction apparatus” is the name and code number of the operator.

  “Information for identifying a destroyed recording medium” is a manufacturer or a serial number of the recording medium.

  “Information for identifying the recording medium destruction device itself” means that the equipment that destroys the recording medium owns multiple devices, such as “No. 1” and “No. 2”. Information.

Next, a method for using the recording medium destruction apparatus 101 of this embodiment will be described.
When using the recording medium destruction apparatus 101 of this embodiment, the door 33 of the main body apparatus 102 is opened, and the hard disk 15 to be destroyed is installed in the internal processing chamber 35.
Then, the door 33 is closed and a predetermined work start switch is turned on.
In the present embodiment, there is a limit switch (not shown) in the door 33, and the drive unit 4 does not operate unless the door is closed.

When the work start switch is turned on, the motor 3 rotates forward as in the previous embodiment, the drive unit 4 descends to deform the hard disk, and the pin 1 penetrates the recording part of the hard disk. Thereafter, the motor 3 rotates in the reverse direction, and the drive unit 4 rises to return to the standby position.
In the present embodiment, the operator-capturing video camera 34 and the destruction object capturing video camera 37 operate during the series of operations described above.
That is, at the same time when the work start switch is turned on, the worker photographing video camera 34 starts photographing, and records the worker's work situation as a moving image. At this time, not only the appearance of the worker but also the vicinity of the installation place of the recording medium destruction apparatus 101 itself is photographed. Such moving picture information is recorded in a memory in the personal computer 103.

Further, the video camera 37 for photographing the object to be destructed performs photographing of the hard disk 15. Therefore, in the video camera 37 for shooting the object to be destroyed, a video before the hard disk 15 is destroyed, a video when the hard disk 15 is destroyed, and a video after the destruction are recorded as moving images.
As described above, when the video camera 37 for photographing the object to be destroyed is installed at a position where the upper surface side of the hard disk 15 to be destroyed can be photographed and at an attachment angle, the serial number of the hard disk 15 is photographed. Thus, it is possible to obtain moving image information for specifying the destroyed recording medium.

  Similarly to the previous embodiment, the personal computer 103 assigns a code number to the hard disk to be destroyed, and video data is recorded in the memory of the personal computer 103 together with the code number. Further, in the present embodiment, bibliographic information is recorded together with a code number.

When a series of operations are completed, or after a large number of hard disks are destroyed and video data and the like are accumulated, a destruction certificate is printed by the printer 104. The destruction certificate has a format as shown in FIG. 4, for example, the date of destruction, the entire photograph of the destroyed hard disk, the enlarged serial number of the photograph of the destroyed hard disk, the name and face photograph of the operator, the work place, Describe the reason for destroying the device and hard disk used for destruction.
The whole photograph of the destroyed hard disk and the enlargement of the serial number of the destroyed hard disk are selected from the images taken by the video camera 37 for photographing the object to be destroyed. Also, the operator's face photograph is selected from the images taken by the operator photographing video camera 34.
Then, the destruction certificate is sent to the client.

Next, a modified example of the present invention will be described.
FIG. 5 shows a modification of the drive unit, and is a cross-sectional perspective view of the main part in a state where the pins of the drive unit penetrate the hard disk 15. FIG. 6 is a partial cross-sectional perspective view of the drive unit of the recording medium destruction apparatus to which an electric force is applied. FIG. 7 is an exploded perspective view of a pin employed in a recording medium breaking device according to still another embodiment of the present invention. FIG. 8 is a cross-sectional view of the pin shown in FIG.

  In the embodiment described above, the drive unit 4 having a plurality of pins 1 is employed, and the pins 1 provided in the drive unit 4 are pierced into the hard disk 15 to destroy the hard disk 15. In addition, A configuration in which an adhesive resin is filled in the case of the hard disk 15 is also recommended.

For example, as shown in FIG. 5, the pin 1 'of the drive unit 4' is hollowed and the adhesive is circulated therein. Then, after the pin 1 'is pierced into the hard disk 15, an adhesive is poured into the case 38 of the hard disk 15 through the pin 1'.
The reason why the adhesive is poured into the case 38 in this way is as follows. That is, if the data is forcibly read from the destroyed hard disk, the hard disk itself must be taken out of the case. For this purpose, it is necessary to pry open the deformed case. If the adhesive is poured into the case 38 of the hard disk 15 as in the present embodiment, the recording surface of the hard disk is peeled off together with the case when the case is opened. For this reason, if a measure for filling an adhesive resin in the case of the hard disk 15 as in this embodiment is adopted, it becomes difficult to remove the hard disk 15 from the case, and the safety is high.

  In the two embodiments described above, the recording medium is destroyed only by a physical force. However, the recording medium can be more completely destroyed by applying an electric force.

For example, as in the embodiment shown in FIG. 6, the electrode 13 is attached to the pin 12 and a high voltage is applied to the pin 12. Therefore, a high voltage flows from the pin 12 pierced into the recording medium to the recording medium, and the recording medium is destroyed.
That is, when the pin 12 is in contact with the recording medium itself or a printed wiring communicating with the recording medium, a current flows through the recording medium, and the recording medium is short-circuited and destroyed. Therefore, according to this configuration, the recording medium is more reliably destroyed.

Further, instead of applying a high voltage or in addition to applying a high voltage, it is also recommended to apply a magnetic force to destroy the recording medium.
For example, permanent magnets are used for the pins 1 and 12. Alternatively, a coil 82 is attached to a part of a pin body 81 made of a magnetic material like the pin 80 shown in FIGS. 7 and 8, and the needle body 81 is electromagnetized by energizing the coil 82.
According to this embodiment, the magnetic recording surface of a hard disk or the like is disturbed by the magnetism of the pins 80, and the hard disk or the like is also destroyed magnetically.

  In the embodiment described above, the recording medium is broken by the pins 1, 12, and 80. However, the recording medium may be broken by a needle-like shape or a conical protrusion.

Further, in the embodiments described above, the configuration in which the pins are moved up and down to penetrate the hard disk 15 is exemplified, but the present invention is not particularly limited to this, and the hard disk can be crushed by a press or a rotating object such as a drill or an end mill. It is possible to adopt a measure for breaking the material, a method for bending or bending by applying a bending stress, a method for breaking by twisting, or the like. In short, the present invention is not limited to a specific measure of destruction as long as the recording medium such as a hard disk is destroyed by a method that is apparently destroyed.
Accordingly, the recording medium is not limited to destruction by physical force, and may be destroyed by applying an electromagnetic wave, a magnetic field, heat, or the like to the recording medium. For example, an optical recording medium such as an optical disc has an aluminum vapor deposition film on its surface, and a signal is recorded on the aluminum vapor deposition film. This aluminum vapor deposition film is heated by applying heat energy from a heat source, or when an electromagnetic wave belonging to microwaves is applied, it generates heat and is destroyed. And since the situation of this destruction can be confirmed visually, there is room for applying the present invention.

It is a front view of the recording medium destruction apparatus which implemented this invention. It is a whole block diagram of the recording-medium destruction apparatus of 2nd embodiment of this invention. It is a partially broken perspective view which shows the internal structure of the main body apparatus of the recording-medium destruction apparatus shown in FIG. It is a front view which shows the example of the destruction certificate printed with the recording medium destruction apparatus of FIG. It is a cross-sectional perspective view of the principal part in the state which shows the modification of a drive part and the pin of the drive part penetrated the hard disk. It is a partial cross section perspective view of the drive part of the recording-medium destruction apparatus which added the electrical force.
