Title: Liquid crystal projector
Inventor: KANAMORI TAKAHIRO
IPC: H04N5/74
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To perform the off-control of the power source of a projector after performing initialization at the time of turning on the power source in the case of turning off the power source by providing a power source control part controlling the on/off of the power source based on a control command from a control part. SOLUTION: When off-operation is performed by a soft power source switch 9a, the control part 15 issues the control command to a focus driving part 11 so as to output a control signal toward a near focusing position or a far focusing position. When the nearest focusing position or the farthest focusing position is detected by a focus position detector 12, the control part 15 stops the control command and outputs a power source turning off command to a power source control part 10 so as to make the power source in an off-state. Since the focus position of a focus driving mechanism 5 is adjusted to the nearest focusing position or the farthest focusing position in the off-state, adjustment is always performed toward the far focusing or near focusing direction in the case of manual focusing at the time of turning on the power source, then adjusting procedure is simplified.
