<p>PURPOSE:To miniaturize a loading drive mechanism of a magnetic recording/ reproducing device by providing a pawl device which interlocks a disk and an inner gear alternately and revolving the pawl device so that an interlocking part at the other side that is already interlocked is released with the revolution of the disk or the inner gear having an interlocking part when the interlocking part of the disk or the gear interlocks said pawl device. CONSTITUTION:A planetary gear is used to a loading drive mechanism. A stop pin 29 is buried the outer circumferential part on the lower surface side of an inner gear 28. While an outer pawl 30 and an inner pawl 31 are attached to a subchassis 32 fixed to a chassis 20. The pawl 30 allows the clockwise revolution and inhibits the counterclockwise revolution of the gear 28 and also prevents the clockwise revolution of a disk 25. While the pawl 31 prevents the clockwise revolution of the gear 28 and the counterclockwise revolution of the disk 25 respectively. When an interlocking part at one side is interlocking a pawl, the interlocking part at the other side is released. In such a way, an exclusive drive source as a pawl device is omitted. Thus a loading drive mechanism of a magnetic recording/reproducing device can be miniaturized.</p> |
