<p>PURPOSE:To eliminate deviation in phase of meshing between a drive arm and a rack at loading of a cassette by providing a clutch means having a power input member so constituted that the member does not mesh with a gear driving a drive arm. CONSTITUTION:The title loader is constituted such that only a transmission gear 6 meshing with a drive arm 8 engaged with a cassette holder 1 with respect to a locked worm wheel 28 and only a clutch disk 15 subject to press fit to a small gear 17 meshing with the transmission gear 6 are driven within a range of play till a motor 10 starts its drive through the loading of a cassette 25 and the activated switch or at the loading of the cassette 25 with interruption of power. That is, the worm wheel 28 is not provided with a tooth meshing with the transmission gear meshing with the gear provided to the drive arm 8. Thus, there is not phase deviation of gears between the worm wheel 28 and a power output member.</p> |
