Abstract: A property management system includes: a management server for managing a property item by a non-contact IC medium; a gate apparatus for reading medium information from the non-contact IC medium; and a destruction apparatus for destroying the property item. Gate passage permission/non-permission information is stored on the management server or the non-contact IC medium and, when destroying the property item, the destruction apparatus transmits the medium information to the management server to perform a destruction completion registration. The gate apparatus includes: a determination device for determining whether the gate passage permission/non-permission information represents permission or non-permission based on the medium information; and a passage prohibition device for prohibiting passage when the determination result is non-permission.

Abstract: A recording medium destruction device adapted to readily destroying a recording medium that is small and irregularly mounted such as an IC mounted on a board. The recording medium destruction device consists mainly of a device mounting part, a destruction part, and an elevating unit. The destruction part includes a number of needles arranged vertically and horizontally in a planar manner and is divided into six sections. In order to destroy recording media such as ICs mounted on a circuit board using the recording medium destruction device, the circuit board incorporating ICs (recording media) to be destroyed is to be put on the device mounting part, whereupon the destruction part is moved down to perforate a number of throughholes in the circuit board.

Abstract: A recorded data eraser 1 defines therein a cavity 2 for insertion of a hard disk drive 20 in the cavity 2 and includes a coil 4 being arranged around the cavity 2 so as to encircle the hard disk drive 20 when the hard disk drive 20 is inserted in the cavity 2, and a DC power supply circuit 8 for producing a magnetic field in the coil 4.

Abstract: A recording medium destruction apparatus capable of confirming that a recording medium no longer required is destroyed to enter an unreadable state is provided. In a recording medium destruction apparatus 91 that drives a pin 1 for destroying a recording medium 15 so that information recorded on the recording medium 15 is irreproducible, there is provided monitoring means 50 for monitoring situations where the recording medium 15 is destroyed. There are provided code number assignment means for assigning a code number to the recording medium 15 to be destroyed, and recording means for recording, when the recording medium 15 has been destroyed, the code number assigned to the destroyed recording medium and the date on which the recording medium has been destroyed.

Abstract: There is provided with a method for dealing with data recording media adapted to readily erase magnetic data recorded in magnetic recording media or destroy data recorded in optical recording media and a device for carrying out said method. Further, there is provided with a method for disposing of electronic device for destroying electronic devices and a device for carrying out said method.

Abstract: An adapter A1 made of a synthetic resin includes an annular frame 1 having an outside diameter of 12 cm, a disk receiving section 2 provided continuously on a lower portion of an inner edge of the frame 1, and a pair of disk pressing sections 3 and 3 provided continuously on an upper portion of the inner edge of the frame 1. The disk receiving section 2 is provided with a circular opening 4 for causing an information recording area of a disk to face an optical reader of a disk player. A disk press-contact projection 7 formed so that a projection height is gradually increased in a disk rotation direction Y is provided on a lower surface of each disk pressing section 3. This adapter A1 can securely install a non-circular optical disk even if the optical disk has a slightly different size, and an installation operation of the non-circular optical disk can be easily performed.

Abstract: An optical disk adapter can position a deformed CD at a predetermined position in a disk-transferring tray by a very simple operation, and is simple in structure and easy in manufacture. At the central portion of an adapter main body (1a) having an external periphery with the same diameter as a 12 cm-CD, a positioning true circular central aperture (2) in which a square CD (C1) with an 8 cm-diagonal length can be fitted in a non-restricted state is provided. The center of this positioning true central aperture (2) is concentric with the center of the adapter main body (1a). The adapter main body (1a) is provided with a rotation prevention protrusion (3) against the disk-transferring tray (71) at the lower surface thereof and a disk clamper passing dented portion (4) at the upper surface thereof.

Abstract: A recorded data eraser for a magnetic storage device for erasing data in the magnetic storage device (M) by a magnetic field generated by a coil (3), into which a capacitor (5) is discharged, has an inductance (H) and an internal resistance (R) of the coil (3) and a predetermined voltage (V) applied to the capacitor (5) set in appropriate amount respectively so as to generate a rebound phenomenon at least once, whereby a direction of the magnetic field is reversed by a reversed current flowing in the coil with a change in polarity of a transient voltage of the discharge of the capacitor into the coil, thereby completely or almost completely erasing recorded data from a storage medium in the magnetic storage device (M)

Abstract: A label printer suitable for label printing of a name card type optical disk as well as a 12 cm-standard complete round disk, wherein a 12 cm-diameter complete round disk loading recessed portion 3 is provided in a disk transferring tray 2 allowed to be inserted and ejected from a printer body 1, and a name card type disk loading recessed portion 4 having a bottom surface positioned lower than the bottom surface of the complete round disk loading recessed portion 3 is provided at the rear portion of the complete round disk loading recessed portion 3. At a rear portion of the name card type disk loading recessed portion 4, an aperture for allowing the movement of the tip protruded portion 11a of a disk holding means 11 in the fore-and-aft direction of the printer body 1 is provided.

Abstract: A protective agent for protecting a print formed on a printing object comprises a high-volatile organic solvent as a dispersion medium and non-water family high polymer emulsion liquid including synthetic resin particles as a dispersoid. This protective agent is sprayed onto a print formed on a printing object by a spray method and then dried. For example, an oil-based first print layer 2 is formed on a surface of an information record member 1, an oil-based second print layer 3 is formed on at least a part of the upper surface of the first print layer 2, and the aforementioned protective agent is applied on the upper surface of the second print layer 3 and dried to form a protective layer 4. Thus, the print will not disappeared even if a hands touches or water is adhered, and no bad influence will be given to the substrate material since the protective agent is excellent in quick-drying property.

Abstract: A disk adapter A is equipped with first and second adapter halves 1 and 2 to be detachably disposed in a disk-placing dented portion 54 provided in a disk tray 53 of a label printer 51. One of the adapter halves 1 and 2 is movable relative to the other thereof in accordance with a movement of a disk pushing member 55 provided in the disk tray 53. When the disk tray 53 is inserted into a printer main body 52, the aforementioned one of the adapter halves is moved in a direction that the one of the adapter halves approaches the other thereof by the disk pushing member 55, whereby the optical disk D is held by and between both the adapter halves 1 and 2.
