A wearable apparatus includes a flexible display device, and a flexible housing that holds the peripheral portion of the flexible display device. The flexible display device is disposed on the uppermost surface of the apparatus to serve as a reference for defining the total length of the apparatus, and the portion of the apparatus below the flexible display device contracts along the direction of the total length.

Wearable apparatus

A disk device is capable of quickly identifying an inserted optical disk. A reading portion obtains disk surface information from an optical disk that is passing, and stores the obtained disk surface information in a storing portion provided in a disk playing device. An identifying portion decides whether or not the disk playing device is able to play the optical disk, based on the surface information.

Disk device with shape identifier

An optical disk device has superior vibration characteristics by preventing vibration of a rotating arm. A desired optical disk is selected from the plurality of optical disks which are stacked and accommodated. The rotating arm is rotated to a working space provided for the desired optical disk. A turntable is positioned, and an optical head is moved to perform the recording/reproduction. Because the tip part of the rotating arm of a cantilever structure is supported by a support member extending along the axial line CL of the optical disk, it has a structure supported by both ends. Thus, the vibration of the rotating arm can be prevented. Because the support member extends along the axial line CL of the optical disk, it passes through a holding hole at the center of the optical disk and a notch provided at the center of a tray, without interference on its way, thereby supporting the rotating arm.

Optical disk device having supported rotating arm

A disc device is capable of suppressing movement of discs remaining on standby. Discs are moved upward and downward, thereby providing an operation space S at a lower side of the desired disc, and a pivotal arm is located in a predetermined position, and thereafter the desired disc is set on the pivotal arm, and recording/reproduction is effected. At this time, the standby discs disposed at the lower side of the desired disc are disposed below the operation space (S), and are fixed by pressing pressing members of disc fixing portions against outer peripheral surfaces thereof.

Disc device having improved suppression of disc movement

To provide an optical disc device in which the number of parts is small, and quietness can be secured with a simple mechanism. The optical disc device includes a main body having a disc insertion/removal port, and a conveying roller for conveying a disc between the disc insertion/removal port and a disc receiving position in the main body, and also includes a swinging lever which is pivotally supported at its proximal end on a supporting shaft within the main body, and has a disc arrival switch fixed thereto, and a detection lever which is pivotally supported at its proximal end on the supporting shaft, and contacts an outer periphery of the disc (which is to be received in the disc receiving position) at its distal end to operate the disc arrival switch, and when the disc is to be inserted into the disc receiving position, the detection lever is projected into the disc receiving position.

Optical disc device having reduced striking sound

An optical disc device capable of sensing exactly whether or not a disc is present is provided. In an optical disc device includes a main body having a disc slot, and a carrying roller for carrying a disc between the disc slot and a disc loading position of the main body, a swinging lever whose base end is supported turnably in an inside of the main body by a supporting shaft and to which a disc arriving switch is fixed, and a sensing lever whose base end is supported turnably by the supporting shaft and whose top end contacts the outer periphery of the disc, which is loaded in the disc loading position, to operate the disc arriving switch are provided.

Optical disc device having improved disc detection

To provide an optical disc device in which an identification and a disc ejection control processing for an optical disc with a high transmitting property and an 8-cm optical disc attached to an adapter can be effected easily and positively. There are provided a body capable of receiving an optical disc therein, an insertion/ejection port capable of insertion and ejection of the optical disc relative to the interior of the body, and rollers which are provided within the body, and rotate, while holding the optical disc therebetween, so as to convey the optical disc into the interior of the body. A mechanical detector, having a contact element for contact with at least one of obverse and reverse surfaces of the optical disc to detect the optical disc, is provided within the body so that an identification and a disc ejection control processing for optical discs can be effected easily and positively.

Optical disc device for identifying an inserted disc

An optical disc device and a disc changer drive capable of achieving a reduction in cost and number of articles and a reduction in size of the disc drive with a simple configuration rather than the prior art and also carrying out a stable playing/writing operation are provided. An optical disc device includes a playing chassis which is supported turnably on a main body of the disc drive and on which a turntable is installed, a substantially Y-shaped cam groove formed on the playing chassis, a driving lever on which a substantially T-shaped cam groove is formed and which transmits a power to a holding portion of the disc, and a turning lever supported turnably on the main body and engaged with the playing chassis and the cam groove of the driving lever via a driving shaft, wherein a turning of the turning lever is followed by a turning of the playing chassis and a movement of the driving lever that follows the turning of the playing chassis to hold a disc as a series of operations.

Optical disk device

The present invention provides a disc drive apparatus capable of identifying a disc (12 cm) having a small data area (8 cm) in central as same as an ordinary 12 cm disc. The apparatus having a light receiving unitand a push switch. The unitis arranged in a position where the unitdetects the disc having the small data area in central when the switchdetects the same, and where the unitdoes not detect a disc (12 cm) having a hole (8 cm) in central when thedetects the same. The apparatus also has an disc identifier for identifying type of the disc based on the detected results of the light receiving units and/or the push switches.

Disc drive apparatus

Space for an optical pickup at a position set aside from a disk accommodating section is to be compressed, thereby to reduce an overall size of an optical pickup device. For such a purpose, the optical pickup unit is held by a screw shaft and a guide shaft parallel to each other, and the screw shaft, the guide shaft, a first connecting plate and a second connecting plate constitute a quadrilateral parallel link. The screw shaft and a chassis holding a turntable are oscillated by a driving motor pivoting on the first connecting plate. In an escape position in which the optical pickup device is away from the disk accommodating section, a gap between the screw shaft and the guide shaft is narrowed.

Optical pickup device and optical disk record/playback device for reducing the size of the record/playback device

Herein disclosed is an optical disk driving apparatus for selectively driving a plurality of optical disks, comprising: a housing; and an optical disk driving unit accommodated in the housing, the optical disk driving unit including: a turntable for selectively retaining the optical disks; a supporting member for rotatably supporting the turntable; a base plate pivotably retained by the housing; a plurality of vibration isolators for isolating the supporting member from outside vibrations by intervening between the supporting member and the base plate; a supporting member fixing mechanism for fixing the supporting member on the base plate by preventing the vibration isolators from isolating the supporting member from outside vibrations; a base plate driving mechanism for driving the base plate to pivotably move with respect to the housing; and a cam gear for transmitting a rotation torque to each of the supporting member fixing mechanism and the base plate driving mechanism.
