Title:
FINE POSITIONING DEVICE
Document Type and Number:
Japanese Patent JPS6391711
Kind Code:
A
Abstract:
PURPOSE:To prevent the occurrence of errors in terms of fine positioning by permitting an actuator to simultaneously give elongation deformation and bending one to parallel springs. CONSTITUTION:When the actuator 7 is activated, a force F applies to an axis X in a position P on an actuator drive axis on a slope 6c at an angle theta1 with respect to the axis X. The force F generates a force component fX in the direction of the axis X and a force component FY in the direction of an axis Y. Due to the force component FY parallel springs 2a and 2b develop fine elongation. Simultaneously, due to the force component FX, the parallel springs 2a and 2b are deformed. Due to the force component FY the parallel springs 2a and 2b are deformed by elongation, a displacement deltaY in the direction of the axis Y is substantially reduced. The angle theta1 can be freely selected according to any conditions.
