Projection display device and remote controller
First Claim
1. A projection display device controllable by a remote controller having a power supply switch portion, the projection display device including a light source, an optical system for forming an optical image in accordance with image information as a result of optically processing light beams emitted from the light source, and a projection lens for projecting the optical image in enlarged form, the projection display device comprising:
- a power supply switch restricting system that includes at least one switching element having one setting which restricts a function of the power supply switch portion of the remote controller which causes a power supply to be turned on/off and another setting which does not restrict a function of the power supply switch portion.

Abstract
In a projection display device which can be controlled by a remote controller, the remote controller includes a power supply switch button for turning on/off a power supply at a body of the projection display device, a zoom adjuster button for adjusting the zooming of a projection lens, and a focus adjuster button for adjusting the focusing of the projection lens. The projection display device body includes a restricting system which can restrict the adjusting functions of these buttons, so that inadvertent operation of any of these buttons does not affect the projection display device.
