Abstract

PURPOSE:To make a device small and to simplify it, by enabling both driving of vertical and horizontal turnings with one magnetic circuit. CONSTITUTION:The arm 3 is supported in free of vertical and horizontal turning with a vertical rotation bearing 4 and a horizontal rotation bearing 5, and the rotation is delivered to the rear arm 7. The vertical drive coil 8 and the horizontal drive coil 9 are fitted to the rear arm 7 so that they are orthogonal each other, and the drive coils 8, 9 are interlinked with the magnetic flux of internal magnet of the magnet case 11 installed on the arm base 10 to obtain the vertical and horizontal drive force with the drive current. The vertical turning speed detector 14 and the horizontal turning speed detector 15 are installed on the base 13 installed on the pipe 6 following to the horizontal turning of the arm 3.
