Patent ID: 7905607

Claim:
A projector that projects an image including keystone distortion, the projector comprising: a first conductive pattern electrically connected to a first terminal section; a second conductive pattern electrically connected to a second terminal section, the second conductive pattern being divided into a plurality of contact areas, the plurality of contact areas being separated from each other by insulated areas that are diagonally oriented with respect to a moving direction of a contact portion, the contact portion comprises two or more contact reeds; an adjusting leg section that changes a tilt condition in a vertical direction of the projector by protruding or retracting, the adjusting leg section including the contact portion that makes contact with at least one of the plurality of contact areas; a voltage detection device that determines a position of the adjusting leg section by detecting a voltage between the first terminal section and the second terminal section based on the contact area contacted by the contact portion; and a keystone distortion correction section that automatically corrects the keystone distortion of the projected image.
