The holding unit 30 includes a base unit 31 and a positioning unit 32. The pedestal 31 also serves as the upper surface wall of the apparatus main body 21. Thereby, the box body 21 is formed in a box shape having a substantially closed internal space. A hole 31a is formed at the position where the hard disk 1 of the base portion 31 is placed so that the upper portion of the cutter 42 of the cutting mechanism 40 can protrude and move upward. The hole 31a has a wide anti-driving portion side so as to be used as a hole for the chips to fall into the chip storage container 50.
[0025]
The positioning part 32 is for holding and positioning the hard disk 1 together with the base part 31, and is provided so that the hard disk 1 can be held upright (vertically). The positioning part 32 includes positioning members 32a and 32b, a clamp member 32c, and a clamp member 32d on the base part 31.
[0026]
The positioning members 32 a and 32 b are formed in an L shape, and their rising portions are arranged to face each other so as to have a gap larger than the thickness of the hard disk 1. The positioning members 32a and 32b are fixed to the base portion 31 with fasteners 32f and 32h such as bolts via bases 32e and 32g. The hard disk 1 has almost the same or slightly different thickness, and it is desirable that the gap between the positioning members 32a and 32b be sized to accommodate these.
[0027]
A plurality of clamp members 32c are attached to the positioning member 32a in the front-rear direction. Each clamp member 32c is screwed so as to pass through a screw hole provided in the rising portion of the positioning member 32a. When the clamp member 32c is screwed in a state where the hard disk 1 is disposed in the gap between the positioning members 32a and 32b, the tip thereof is brought into contact with the side surface of the hard disk 1, and the hard disk 1 is brought into contact with the rising portion of the positioning member 32b. The As a result, the hard disk 1 is clamped in the front-rear direction.
[0028]
A plurality of clamp members 32d are attached to the positioning member 32b in the front-rear direction. Each clamp member 32d is screwed so as to pass through a screw hole provided in a portion protruding from the rising portion of the positioning member 32b toward the positioning member 32a. With the hard disk 1 placed in the gap between the positioning members 32a and 32b and clamped by the clamp member 32c, the clamp member 32d is screwed in so that its tip abuts against the upper surface of the hard disk 1, and the hard disk 1 is also clamped in the vertical direction. Will be. As a result, the hard disk 1 is clamped to the holding unit 30 in the horizontal direction. In addition, since it has the part which protrudes from the standing part of the positioning member 32b to the positioning member 32a side, the hard disk 1 arrange | positions the hard disk 1 in the clearance gap between the positioning members 32a and 32b from the side.
[0029]
The cutting mechanism unit 40 includes a rotary cutter 42 that cuts a part of the hard disk 1 held by the holding unit 30, a drive unit 42 that rotationally drives the cutter 42, and a moving operation unit that moves the cutter 42 to a cutting position. 43.
[0030]
The cutter 41 is formed in a disk shape having a saw blade on the entire outer periphery thereof and is disposed in the box body 21. The cutter 41 is arranged vertically so as to intersect the hard disk 1 immediately below the hard disk 1 held by the holding unit 30. In the illustrated example, since the hard disk 1 is disposed so as to extend in the left-right direction, the drive unit 42 is disposed so as to extend in the horizontal direction (the front-rear direction in the illustrated example).
[0031]
The saw blade of the cutter 41 is formed in such a shape that the main generation side of the chips generated when the hard disk 1 is cut is the side opposite to the driving portion. The destruction by cutting the hard disk 1 with the cutter 41 can surely destroy the magnetic disk 2 as compared with the destruction using a hammer or the like. Further, even if the magnetic disk 2 is composed of a plurality of sheets, all of them can be cut and destroyed. Since the fasteners 4c and 3c are not damaged when the hard disk 1 is destroyed, the fasteners 4c and 3c are removed after the hard disk 1 is destroyed, and the components (the magnetic disk 2 and the spindle motor) in the disk case 4 are removed. 3 and the actuator 5) are easy to disassemble and take out, and these parts can be selected and recycled easily.
[0032]
The drive unit 42 includes a motor 42a driven by AC 100V, and a gear mechanism 42b that decelerates the rotational force of the motor 42a and transmits it to the drive unit 42. Electric power is supplied to the motor 42a through a power supply terminal portion 42c provided on the back surface of the box body 21.
[0033]
The motor 42a is connected to the power terminal 42c via an interlock switch (not shown), an operation switch 42d, and a stop switch 42e. The interlock switch is provided so as to be closed when the protective cover 22 is closed and to be opened when the protective cover 22 is opened. Accordingly, since the drive unit 42 is driven only when the protective cover 22 is closed, the cutter 41 that rotates during the cutting operation of the cutter 41 may be injured, or the chips may be scattered and injured. It can be prevented and has excellent safety.
[0034]
There is provided a power lamp 42f that is turned on when the operation switch 42d is pushed and the cutting mechanism 40 is operated, and is turned off when the stop switch 42e is pushed and the cutting mechanism 40 is stopped. The operation switch 42d, the stop switch 42e, and the power lamp 42f are disposed on a control panel 42g provided on the upper surface of the platform 31.
[0035]
The moving operation unit 43 includes a moving mechanism 45 that moves the cutter 42 to a cutting position by moving the cutting mechanism 40 upward, and an operation knob 46 for applying a driving force to the moving mechanism 45. Yes.
[0036]
The moving mechanism 45 is structurally connected between the motor 42a and the operation knob 46 by a plurality of mechanism members 45a and 45b. The mechanism member 45a is provided between the central portion of the motor 42a and one end portion of the mechanism member 45b, and is provided so that the motor 42a can be rotated about the mechanism member 45b side as a rotation axis. This rotation is clockwise when viewed from the side, and moves at right angles to the plane of the hard disk 1, so that the cutter 41 can be reliably cut without being deformed during cutting. Further, according to the present embodiment, since the drive unit is moved by rotating, the structure of the moving operation unit 43 can be simplified. The mechanism member 45b is provided between the mechanism member 45a and the operation knob 46, and converts the operation force of the operation knob 46 into the rotational force of the mechanism member 45a.
[0037]
In this embodiment, since the cutter 41 is installed vertically (that is, the motor 42a is horizontal), when the hard disk 1 is cut, it can be cut vertically as shown in the cutting section 44 of FIG. . In order to increase the amount of cut into the magnetic disk 2 without cutting the spindle motor of the hard disk 1 as shown by 44 'in FIG. 1, the motor 42a is tilted and the cutter 41 is tilted. In this way, the information recorded on the magnetic disk 2 can be destroyed more reliably.
[0038]
The operation knob 46 is composed of a single triangular manual handle and is exposed on the front surface of the box body 21. When the operator manually rotates the operation knob 46, the moving mechanism unit is operated to move the cutting mechanism 40 upward.
[0039]
By using the operation knob 46 as a triangular manual handle, the following effects can be obtained. When the mechanism that raises or lowers the cutter 41 is electrically operated, the cutter 41 moves at the same speed when the hard disk 1 is crushed, for example, even when the saw blade of the cutter 41 hits a hard portion of the hard disk 1. There is a possibility that 41 saw blades may be lost. On the other hand, in this embodiment, when the saw blade of the cutter 41 hits a hard portion of the hard disk 1, the cutter 41 can be moved manually so that the saw blade is not chipped. The hard disk 1 can be reliably cut while preventing the saw blade of the cutter 41 from being chipped. That is, since the operation knob 46 is structurally connected to the moving mechanism portion 43b of the cutter 41, the operator can determine whether or not the hard part is cut by the touch (hand feeling) of the operation knob 46. As a configuration. Further, since the operation knob 3a has a triangular handle, the cutter 41 cannot be moved greatly at a time by the movement of the operator's hand, and the cutter 41 can be continuously moved unless the hand is changed. It can not be done. As a result, it is possible to easily prevent an operator from accidentally cutting the hard disk 1 too much.
[0040]
Furthermore, the cutter movement amount display unit 47 is installed on the upper surface of the box body 21 together with the operation switch 42a, the operation stop switch 42d, and the like so that the movement amount of the cutter 41 can be visually confirmed by digital display. Thereby, the cutting amount of the hard disk 1 can be confirmed more reliably.
[0041]
The chip storage container 50 is opened adjacent to the hole 31 a on the upper surface and is adjacent to the counter drive part side of the cutter 41. Combined with this configuration, the hard disk 1 is formed in such a shape that the main generation side of the chips generated when the saw blade of the cutter 41 cuts the hard disk 1 is the side opposite to the driving portion. Most of the chips generated when cutting with the cutter 41 can be dropped and stored directly in the chip storage container at the time of cutting.
[0042]
This chip storage container 50 is installed so that it can be taken out from the inside of the apparatus box 20. A cover (not shown) for taking out the chip storage container is detachably provided on the side surface of the device box 20. With this configuration, the chips generated by cutting the hard disk 1 can be easily discarded.
[0043]
