OPTICAL MEMBER DRIVING APPARATUS AND PROJECTION TYPE IMAGE DISPLAY APPARATUS |
| 摘要 |
An optical member driving apparatus includes an optical member for changing an optical path, a plurality of actuators each having a movable member which is controlled to move in one direction, a plurality of connecting members which connect edge portions of the optical member positioned on two axes orthogonal to each other and the movable members of the plurality of actuators, respectively, a position detector for detecting a moving amount of the movable member of each actuator and outputting a detection signal indicating the moving amount, and a controller for controlling movement of the movable member of each actuator based on the detection signal from the position detector so as to keep an intersection point of the two axes at constant position. |

1. An optical member driving apparatus comprising:
an optical member for changing an optical path; a plurality of actuators each having a movable member which is controlled to move in one direction; a plurality of connecting members which connect edge portions of the optical member positioned on two axes orthogonal to each other and the movable members of the plurality of actuators, respectively; a position detector for detecting a moving amount of the movable member of each actuator and outputting a detection signal indicating the moving amount; and a controller for controlling movement of the movable member of each actuator based on the detection signal from the position detector so as to keep an intersection point of the two axes at constant position. |
