  • Loading mechanism for disk recording and/or reproducing device
    Patent number: 6058090
    Abstract: A loading mechanism for a compact disk (CD) recording and/or reproducing device, comprising: a motor; a set of gears; a lever plate; a gliding piece; and a CD carrier. Mounting and dismounting of the CD is driven by a combination of a linear and a rotatory movement, allowing the operations of inserting/ejecting and raising/lowering of the CD to be driven by a single motor. The arrangement provides stable movements with minimum vibrations, such that a high reliability of reading and recording data is achieved.
