In correspondence with the left and right external ears of a listener occupying a seat, a three dimensional sound field reproducing unit includes at least more than two speakers disposed on a headrest on the top of a backrest of the seat, and three dimensional signal processing means which converts an output signal from a sound source into a three dimensional sound field signal for supplying it to each of the speakers. Three dimensional sound field with high accuracy and fidelity is reproduced near the external ears of the listener.

Vehicle-mounted stereophonic sound field reproducer

A vehicle-mounted three dimensional sound signal reproducing&#x2022;silencing unit includes at least two speakers disposed for each of seats to be occupied by listeners so as to generate a three dimensional sound field space in a region inclusive of left and right external ears of each of the listeners, and three dimensional signal processing means for converting an output signal from a sound source into a three dimensional sound field signal for supplying it to each of the speakers, thereby reproducing a three dimensional sound field with rich presence for each of the seats. The unit also includes antiphase signal generating means for supplying a silencing signal to the three dimensional signal processing means, thereby silencing sounds for each of the seats without giving an effect on the other seats.

A disk device including a first disk holder movable with disk conveyance, a second disk holder opposed to a groove portion formed in the first disk holder and holding a disk grippingly in cooperation with the first disk holder when the first disk holder holds the disk, and a supporter which supports the first disk holder and which causes a support position for the first disk holder to be shifted in accordance with the movement of the first disk holder to be shifted in accordance with movement of the first disk holder, realizes reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality of operations, improved vibration resistance and less expensive manufacturing cost.

Disk device

A device installation apparatus for a mobile body is disposed in a position sandwiched between a driver's seatand a assistant driver's seatin an automobile vehicle, and is constituted by a center console box, as an installing means, movable along a rail portion, in which a desired device such as a CD player, a cassette tape player, a DVD playeror the like can be installed. Having been constituted as above, it allows passengers seated other than in front seats an easy access to the desired device, remarkably improving the convenience of the apparatus.

Apparatus installing device for mobile body

A disk device capable of storing a plurality of disks therein includes a disk holder capable of changing its vertical position to hold a disk, a driver to drive the disk holder, and the disk holder performs a rotational movement and the changing of its vertical height by means of the same driving mechanism of the driver. The disk device realizes a reduction in size and number of parts, prevention of damage to disks, a shortened operation time for a plurality of operations, improved vibration resistance, and a reduced manufacturing cost.

A disk device realizing reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality of operations, improved vibration resistance and less expensive manufacturing cost is provided. The disk device capable of storing a plurality of disks includes an operation setting means to actuate the disk holding means according to an operation mode of the disk, and an operation mode switching means to switch the operation mode of the operation setting means based on contents of disk operation.

Disk device holding a plurality of disks at its inner diameter

A disk device realizing reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality operations, improved vibration resistance and less expensive manufacturing cost is provided. The disk device capable of storing a plurality of disks loosely fitted and supported at its inner diameter, including separable loose mandrel mechanisms, when the mandrel mechanism is loosely fitted to the disk, the disk holder holds the disk, and one end of the a second mandrel mechanism is connected to another end of a first mandrel mechanism in a state that the disk is raised to a height abutting upon a support of a ceiling side formed on the first mandrel mechanism.

In response to a voice request from a facility judgment means which judges the location of such a facility from the current position selected in advance based on the current position and map data, the voice guidance generated by guidance synchronizing means is converted by stereophonic or three dimensional signal processing means into a stereophonic or three dimensional sound field signal, and outputted to at least two or more speakers which generate a stereophonic or three dimensional sound field reproducing space corresponding to the left and right external ears of a listener. The distance to, and the direction of, the facility that has been selected in advance are informed by the movement of an image of a stereophonic or three dimensional sound with rich presence.

Operation supporting apparatus

A disk device realizing reducing in size and number of parts, prevention of damage to disks, shortening operation time for plurality of operations, improved vibration resistance and less expensive manufacturing cost is provided. In the disk device when a disk is reproduced, a disk reproducing mechanism is moved to become a center of disk coincident with a center of turntable thereof, a first disk holding mechanism is moved downward to load the disk on the disk reproducing mechanism, then a disk clamping mechanism is moved to clamp the disk loaded on the disk reproducing mechanism, and the disk is reproduced after the first and second disk holding mechanism release the disk and are taken away from the disk.

A steering system for mobile unit has a steering section for steering a mobile unit having an operation section on a part thereof, and a control section for enabling the mobile unit to be steered, when the steering section is set at a first installed position, and enabling the operation section to make an operation on the device, when the steering section is set at a second installed position.

Steering system for mobile unit

A disk device includes a disk playing section provided with a pickup reading recorded information on a disk and a rotatable turntable mounting a disk, a damper section supporting said disk playing section to float and a rotatable base section which disposes said disk playing section through said damper section and which forms an engaged section by an engaging action and an engaging section which engages with an engaged section. The invention is further characterized in that when said base section is rotated to a disk playing position, said engaged section is adapted to engage with said engaging section.

Disk device with rotatable playing section

A disk device providing disk storage and disk playing capabilities. The disk storage being provided along a vertical column. Upon the retrieval of a desired disk from the disk storage, the desired disk is rotated around the column so that it may move up and down the column into a playing position. Upon reaching the playing position the disk is provided to a disk playing device for playing the disk.

Disk device with support means

A central console unit is disposed in a position between a driver's seat and a front-passenger's seat in a motor vehicle as a mobile body and disposes desired devices such as a CD player, a cassette tape player, a DVD player, or the like, is arranged to allow the central console unit to be positioned along a rail to a predetermined position corresponding to each of the seats in the motor vehicle.

Device installation apparatus for moving body

A disk device is provided with a disk insertion/ejection means which performs insertion and ejection operations of a disk to the inside and outside the device and a displacement means which displaces said disk insertion/ejection means along a direction of disk insertion/ejection and wherein said displacement means is adapted to displace the disk insertion/ejection means in either a direction of disk insertion or disk ejection based on the operation of said disk.
