Title:
MULTISHAFT POSITIONING DEVICE
Document Type and Number:
Japanese Patent JP3531317
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress a load to a driving mechanism by driving the other side shaft to minimize the inertia moment when one side shaft is driven, before a controlled part is driven from the present position to an object position as to the one side shaft.
SOLUTION: A servooperator 18 outputs a driving signal to a tilt shaft driver 17 in order to make coincide the object position data J5 of the tilt shaft, and the tilt shaft position data J2 output from a position sensor 15. That is, before the inertia moment is increased by rotating a lamp body 3 around the tilt shaft, the lamp body 3 is rotated around a pan shaft, and then, the lamp body 3 is rotated around the tilt shaft. Consequently, the lamp body 3 can be rotated around the pan shaft, without making a servocontrol system unstable by the increase in the inertia moment in the rotation around the pan shaft.
