OPTICAL MEMBER DRIVING DEVICE AND PROJECTION IMAGE DISPLAY APPARATUS |
| 摘要 |
An optical member driving device of the present disclosure includes an optical member for changing an optical path, the optical member having a parallel flat plate shape; a driving mechanism having a movable portion controlled to move in a direction orthogonal to a surface of the optical member by a drive signal, the driving mechanisms being disposed outside the optical member; a connecting member rotatably connecting an end of the optical member and the movable portion of the driving mechanism on two axes orthogonal to each other at a surface center of the optical member; a support portion disposed between the end of the optical member and the movable portion of the driving mechanism, the support portion rotatably pivoting the connecting member; and a controller configured to control the movable portion of the driving mechanism. |

1. An optical member driving device comprising:
an optical member for changing an optical path, the optical member having a parallel flat plate shape; a driving mechanism having a movable portion controlled to move in a direction orthogonal to a surface of the optical member by a drive signal, the driving mechanism being disposed outside the optical member; a connecting member rotatably connecting an end of the optical member and the movable portion of the driving mechanism on two axes orthogonal to each other at a surface center of the optical member; a support portion, disposed between the end of the optical member and the movable portion of the driving mechanism, for rotatably pivoting the connecting member; and a controller configured to control the movable portion of the driving mechanism. |
