Abstract
A projector includes an optical path change device placed between a light modulation device and a projection optical device. The optical path change device has an optical member holding part that holds an optical member that a light modulated by the light modulation device enters, and a supporting member that swingably supports the optical member holding part. The supporting member is supported by a holding member that holds the light modulation device or the projection optical device.
Claims15
A projector comprising:
- a light source;
- a light modulation device that modulates a light output from the light source;
- a projection optical device that projects the light modulated by the light modulation device;
- an optical path change device placed between the light modulation device and the projection optical device and changing an optical path of the light modulated by the light modulation device;
- and
- a holding member that holds the light modulation device or the projection optical device, wherein
- an opening through which the light modulated by the light modulation device passes is provided in the holding member,
- the optical path change device has an optical member that the light modulated by the light modulation device enters, an optical member holding part that holds the optical member, and a supporting member that swingably supports the optical member holding part, and
- the supporting member is supported by the holding member.
