Claims (1)
ーンへ映像を投影する時に光路切替えをミラー装
置において、ミラー部の直線動作を行う駆動部と
、位置決めセンサーと、このセンサーからの情報
に基づき前記ミラー部の位置決め制御回路と、前
記ミラー部、駆動部間結合スライド機構とを有し
、ミラー部停止時の振動を弱め、光路切替え時間
を短縮したことを特徴とするミラー装置。 A mirror device that switches optical paths when projecting images from multiple projectors or projectors onto one screen includes a drive unit that moves the mirror unit in a straight line, a positioning sensor, and positioning control of the mirror unit based on information from this sensor. What is claimed is: 1. A mirror device comprising: a circuit; and a coupling slide mechanism between the mirror section and the drive section, which reduces vibration when the mirror section is stopped and shortens optical path switching time.
