Patent number: 7073184Abstract: A disk apparatus includes a stock section for storing a plurality of stacked disks, a disk transfer mechanism for withdrawing a selected disk out of the stock section, a selection mechanism for causing the selected disk and the disk transfer mechanism to face each other, a rotating section for driving the disk, a common motor, a power transmission mechanism for selectively transmitting the power of the motor to the selection mechanism and to the disk transfer mechanism, and a switching mechanism for switching between a first switching state in which the power of the motor is transmitted to the disk transfer mechanism and a second switching state in which the power of the motor is transmitted to the selection mechanism. The switching mechanism is switched between the states by the moving force of the disk transfer mechanism moving between a transfer-force transmitting position and a transfer-force interrupting position.Type: GrantFiled: January 13, 2003Date of Patent: July 4, 2006Assignee: Alpine Electronics, Inc.Inventor: Akira Otsuki

Patent number: 6963519Abstract: A disc device comprising a transfer unit operable to provide a transferring force to a disc inserted from the outside to transfer the disc into a storage area in the device, a sensor unit for detecting the position of the inserted disc, and a control unit for controlling a operational speed of the transfer unit. The control unit controls the operational speed of the transfer unit in the disc loading direction at a low-speed until the disc inserted from the outside reaches the transfer unit. The control unit then adjusts the operational speed of the transfer unit in the disc loading direction from a low-speed to a high-speed when the sensor unit detects that the disc is inserted into the position in which a transferring force from the transfer unit is given to the disc, or after a predetermined period of time has elapsed. Accordingly, the disc device reduces operation noise and resistance when the disc is inserted.Type: GrantFiled: November 13, 2002Date of Patent: November 8, 2005Assignee: Alpine Electronics, Inc.Inventors: Akira Otsuki, Masatoshi Ito

Patent number: 6947357Abstract: A changer-type disk device includes a disk storage section holding disks arranged in the axial direction of the disks; a drive unit for reproducing and/or recording information from/in a disk selected from the disks in the disk storage section; a drive activating mechanism for moving the drive unit back and forth between a drive position where the selected disk is driven and a retracted position where no disk is driven; and pressing members. The pressing members come into pressure contact with the circumferential edges of the waiting disks held in the disk storage section to push them toward the disk storage section from the outside in the radial direction, and are separated therefrom when the drive unit is moved from the drive position to the retracted position. Accordingly, the waiting disks can be locked in the radial direction; thus, a rattle noise occurring from the waiting disks during driving of the selected disk can be reduced.Type: GrantFiled: November 4, 2002Date of Patent: September 20, 2005Assignee: Alpine Electronics, Inc.Inventor: Akira Otsuki
