Abstract
A rotary position control device is provided with a three-rotary position controlling mechanism. The control device includes a disk member having a toothed portion on its circumferential part, to which an output shaft is secured in order to drive a driven source coupled to the output shaft. The disk member further has a circumferentially spaced slot having a recessed portion provided halfway between the both ends, the both ends and the recessed portion functioning as first, second and third stopper portions which receive a rod member disposed in the slot. The disk member stops its rotation when the rod member engages the both ends of the slot of the disk and also when the rod member engages the recessed portion, this third stop position of the disk member being achieved only when the electromagnetic solenoid is energized, thus causing the required relative movement between the output shaft and the driven source coupled to the output shaft. A motor as a motive source is housed in the control device to rotate the disk, which is supplied a driving signal from the exterior of the rotary position control device.
