Abstract
A velocity-reduced drive system (1) is used to operate a movable member of a video camera or a combined camera-and-VTR unit at a reduced velocity. The drive system comprises a micro or flat motor (5) supported in cases (2), (3) and (4), a worm gear (6) rotatably supported by the cases, a worm wheel meshed with the worm gear, first power transmission means (11), (12) and (12) for transmitting rotational force of the motor (5) to the worm gear (6), and second power transmission means (14), (15) and (16) for transmitting rotational force of the worm gear (6) to an output shaft (7) to be coupled to the movable member.
Claims8
A velocity-reduced drive system comprising:
- (a) a motor housed in at least one case of a plurality of cases;
- and
- (b) a reduction gear unit including a worm gear rotatably supported by at least two of said cases, first power transmission means for transmitting rotational force of said motor to said worm gear, and second power transmission means for transmitting the rotational force of said worm gear to an output shaft, said second power transmission means including a worm wheel meshed with said worm gear.
