Abstract: A seal structure or a sealing method that seals the housing (case) and allows the signal line to pass through a seal portion of the housing is provided. A recessed level difference is formed on at least one of junction faces of first and second housing units (case units) joined together, and, at a portion including the recessed level difference, a first sealing material (double-faced adhesive sheet), the signal line (flexible cable) or circuit unit, and a second sealing material are held between the first housing unit and the second housing unit. The adhesiveness and flexibility of the first sealing material and the elasticity of the second sealing material allow the signal line or circuit unit to pass through the seal portion while maintaining airtightness.

Abstract: An information processing device including a personal authentication function by reading a fingerprint. The device has a detection structure having an improved detection function. The information processing device (mobile telephone device 2) has a fingerprint read function and a case (4) having a window (20), a fingerprint sensor (22) arranged in the case and having a sensor surface (24) exposed to the window, and a frame (electrode 42) arranged inside or on the case and forming an opening (50) for exposing the sensor surface of the fingerprint sensor from the window, so that the frame is in contact with a finger through the window of the case.

Abstract: A compact inexpensive optical disk drive adaptable to high-density optical disks is provided by improving a loading mechanism for an optical disk. A mechanism for loading an optical disk, in or from which information is optically recorded or reproduced, into the body of an optical disk drive is mounted on a chassis. The loading mechanism consists of a spindle motor, a lift plate, and a sheet loader. The spindle motor rotates an optical disk. The spindle motor is placed on the lift plate. The sheet loader moves the lift plate vertically to the chassis so as to attach or detach the spindle motor to or from the optical disk. In the storage device, the tilt of the lift plate relative to the chassis is adjusted at three points on the lift plate. Blade springs for constraining the lift plate to move towards the optical disk are interposed between the chassis and lift plate.

Abstract: A loading mechanism by which a disk cartridge can be loaded into a disk drive apparatus includes a mechanism for opening and closing a shutter of the disk cartridge; an elevating plate on which a spindle motor and an alignment pin for positioning the cartridge are mounted; and an oblique surface for moving the elevating plate onto the cartridge side for cartridge insertion. In one case, a front end portion of a first alignment pin is elliptically cylindrical, and only a front end portion of a second alignment pin is curved. The second alignment pin is offset onto the rear side of the apparatus. In another embodiment, a shutter sliding member includes: first and second sliding pieces which slide in a guide groove of a guide frame forming an insertion passage of the cartridge; and a torsion spring. In the first and the second sliding pieces, a shaft portion engages one end of the torsion spring, and a flange interposes the guide groove.

Abstract: An optical storage device adapted to accept a cartridge composed of a cartridge case and an optical recording medium accommodated in the cartridge case. The optical storage device includes a base, a light source mounted on the base, an optical head having an objective lens for focusing light from the light source onto the optical recording medium, and a photodetector mounted on the base for detecting a regenerative signal from reflected light from the optical recording medium. The optical storage device further includes a cartridge holder having a main surface for holding the cartridge inserted in the optical storage device. The main surface of the cartridge holder is integrally formed with first and second spring arms adjacent to each other and extending substantially along a first side of the cartridge holder. The main surface of the cartridge holder is further integrally formed with a third spring arm extending substantially along a second side of the cartridge holder opposite to the first side.
