Title: Displacement enlarging device
Inventor: OIKAWA TOMOHIRO
IPC: G02B26/12
Filed: 1990-11-29
Abstract: PURPOSE:To improve the displacement enlarging accuracy of the title device by using a state, where a prescribed voltage is applied in order to make the close adhesion between an electromagnetic actuator and a force applying section perfect, as a displacement starting point. CONSTITUTION:When, for example, reverse forces are applied to force acting sections C1 and C2 as tensile forces, blocks B1 and B3 respectively rotate clockwise and counterclockwise and the entire body of this displacement enlarging device deforms to an arch-like shape. When, on the contrary, a pair of compressive forces are applied to the sections C1 and C2, the entire body of the device deforms to an upward arch shape. Accordingly, the displacement of the sections C1 and C2 is enlarged by utilizing this deformation. In addition, a prescribed voltage V<p> is applied so that electromagnetic actuators 13 and 15 can be closely attached to a fixed frame 17 and sections C1 and C2, respectively, during the standby time from time ta to time tb and the time tb when the state is stabilized is used as a displacement starting point. When the actuators 13 and 15 are driven synchronously to optical scanning and a cylinder lens 2A is made to make single harmonic motion in the direction of the optical axis after the voltage Vp is applied, excellent correction of the curvature of field can be realized.
