PROJECTOR AND PORTABLE TERMINAL

摘要

According to one embodiment, a projector includes a light source unit, a light scanning unit, and a focus controller. The light source unit emits laser light. The light scanning unit includes a holder and a reflective surface. The holder is capable of a first rotation operation around a first direction. The reflective surface is held by the holder and is capable of a second rotation operation around a second direction intersecting the first direction. The light scanning unit scans the laser light by the first and second rotation operations. The focus controller is provided between the light source unit and the light scanning unit in an optical path of the laser light to modify a convergence of the laser light. An angle between a plane including the first and second directions, and an image surface is not less than 80 degrees and not more than 100 degrees.

1. A projector, comprising:
a light source unit configured to emit laser light; a light scanning unit including
a holder capable of a first rotation operation around a first direction, anda reflective surface held by the holder and capable of a second rotation operation around a second direction intersecting the first direction, the laser light being configured to be incident on the reflective surface,the light scanning unit being configured to scan the laser light by the first rotation operation and the second rotation operation; and a focus controller provided between the light source unit and the light scanning unit in an optical path of the laser light to modify a convergence of the laser light in conjunction with the first rotation operation, an angle between a plane and an image surface being not less than 80 degrees and not more than 100 degrees, the plane including the first direction and the second direction, the image surface being formed by the laser light emitted from the light scanning unit.
