Abstract
An apparatus for angularly positioning a rotary member such as turn table, etc. by employing two separate motors. First motor is connected to drive the rotary member in a work operation and second servo motor is connected to drive the rotary member in a servo angular positioning movement. A power transmission mechanism is connected with the first motor to rotate the rotary member in the work operation and a coupling mechanism including a single position clutch therein is connected with the second motor to rotate the rotary member in the servo movement. A first detector is provided to detect a predetermined angular reference position of the single position clutch and a second detector is disposed to detect a predetermined reference position of the rotary member and thereby allowing the single position clutch to engage. A controller is connected with the second motor and with the first and second detectors to regulate the servo operation.
