  • Storage apparatus
    Patent number: 6766394
    Abstract: A battery pack is detachably provided for a drive main body. When carrying, an interface card and a connector cable are detachably supported and fixed to the drive main body by a holder member, thereby packaging. A power source is supplied from an upper apparatus to a control IC circuit unit of a device via the interface card. Only when both of the power supply from the upper apparatus and the power supply from an external power source unit are detected, the power source from the external power source unit is supplied to a device circuit unit, thereby making the device circuit unit operative.

  • Optical data recording and reproducing apparatus with easily assembled components
    Patent number: 6567363
    Abstract: The present invention is intended to produce an optical disk drive unit, which is an optical data recording and reproducing apparatus, compactly and to improve the efficiency in assembling components of the drive unit. The optical disk drive unit consists of a driving mechanism and a printed wiring board. The driving mechanism assists in loading a cartridge, which accommodates an optical disk that is a commutative medium, in a main unit, drives the cartridge, and reads or writes data from or on the optical disk. A circuit for driving and controlling the driving mechanism is mounted on the printed wiring board. The driving mechanism can be divided into a load/ejection mechanism and a reading/writing mechanism. The load/ejection mechanism is a united body consisting of a cartridge identification sensor, an ejection motor for ejecting a cartridge, and a bias magnet assembly.
