Document Type and Number:
Japanese Patent JPS63125857
Kind Code:

Abstract:

PURPOSE: To easily adjust the driving stroke with high accuracy by forming a diamond-shaped lever by four levers, interposing a magnetic fluid type actuator between both elbows of one opposite angle of the diamond-shaped lever, and connecting therebetween.

CONSTITUTION: The respective end portions of each pair of arms 2, 3 on both sides are movably connected by elbows 4, 5, 6 to form a diamond-shaped lever 7, and a magnetic fluid type actuator 12 is interposed between both elbows 6 of one opposite angle. In this arrangement, as the turning radius of the diamond-shaped lever 7 can be adjusted by controlling the exciting current of an electromagnetic coil 17, the driving stroke can be easily adjusted with high accuracy so as to improve the reliability.
