Projector having a projection angle adjusting mechanism
First Claim
1. A projector, comprising:
- a fiber bundle including a plurality of cores fixedly arranged on an input plane and an output plane;
a laser beam source for emitting a laser beam having a directivity;
an optical guide unit for modulating the laser beam emitted from the laser beam source into a two-dimensional image and guiding the modulated laser beam as the two-dimensional image to the input plane of the fiber bundle;
a projection lens for enlarging and projecting the laser beam, as the two-dimensional image, emerging from the output plane of the fiber bundle to a display space; and
a projection angle adjusting mechanism for adjusting a projection angle of the projection lens.

Abstract
A multipurpose projector is provided with a fiber bundle including a plurality of cores fixedly arranged on an input plane and an output plane, laser beam sources for emitting laser beams having directivities, an optical guide unit for modulating the laser beams emitted from the laser beam sources and guiding the modulated laser beams to the input plane of the fiber bundle, a projection lens for enlarging and projecting the laser beams emerging from the output plane of the fiber bundle to a display space, and a projection angle adjusting mechanism disposed on the side of the output plane of the fiber bundle for adjusting projection angles of the laser beams projected from the projection lens. Thus, the projector can have its projection space freely operated and enlarged to extend its application not only to image display, but also to illumination and decoration with colored light.
