  • Publication number: 20130044298
    Abstract: Disclosed are a focus regulating apparatus for use with a projector and a projector using the same. The apparatus has a structure which is designed to overcome asymmetry in focus regulation due to the optical characteristics of the projector. The focus regulating apparatus of a projector includes: a focus regulator, which is provided in a projection lens unit of a projector main body so that the focus can be regulated by rotating a lens barrel of the projection lens unit; and an actuator, which gears with the focus regulator and moves rectilinearly with respect to the projector main body, thereby causing the focus regulator to rotate. The rotation of the focus regulator is varied when the actuator rectilinearly moves at a constant speed. The apparatus thus enables an asymmetry in focus regulation to be overcome when a screen size for the projector is adjusted.
