Zusammenfassung: | To provide a projector that comprises a shutter unit and is small-sized.SOLUTION: A projector of the present invention comprises: a light source device; a light modulator that forms image light; a projection optical device that projects the light modulated by the light modulator on a projection target surface; an optical member that guides the light from the light modulator to the projection optical device; and a shutter unit that is arranged between the optical member and the projection optical device and can block a light path between the optical member and the projection optical device. The shutter unit has a drive motor, a transmission member that transmits a rotational driving force of the drive motor, and a shutter member that is arranged on the light path of the light emitted from the optical member and moves in conjunction with the movement of the transmission member. The shutter member is provided opposite to an opposing area opposite to the projection optical device. At least part of the transmission member is provided opposite to the opposing area. The drive motor is provided outside the opposing area.SELECTED DRAWING: Figure 4
【課題】シャッターユニットを備えるとともに小型のプロジェクターを提供する。【解決手段】本発明のプロジェクターは、光源装置と、画像光を形成する光変調装置と、光変調装置により変調された光を被投写面に投写する投写光学装置と、光変調装置からの光を投写光学装置へと導く光学部材と、光学部材と投写光学装置との間に配置され、光学部材と投写光学装置との間における光路を遮断可能なシャッターユニットと、を備える。シャッターユニットは、駆動モーターと、駆動モーターの回転駆動力を伝達する伝達部材と、光学部材から射出された光の光路上に配置され、伝達部材の移動に連動して移動するシャッター部材と、を有し、シャッター部材は、投写光学装置に対向する対向領域に対向して設けられており、伝達部材の少なくとも一部は、対向領域に対向して設けられ、駆動モーターは、対向領域の外側に設けられることを特徴とする。【選択図】図4 |
