Projector for business

Abstract

Abstract PURPOSE:To incline and support precisely an original platen and display the inclination state by supporting the original platen on a device body with plural leading-out hinges and varying the extent of leading-out to hold the original platen. CONSTITUTION:A movable original platen 2 supported by plural leading-out hinges 3 which can vary freely and hold the extent of leading-out is provided on a fixed original platen table 1a of a projector 1 for business is which a light source for projection, a condenser lens, etc. are stored. Since one pieces 3a of these hinges 3 are fixed to the side of the movable original platen 2 and the other 3b are held freely slidably on the side of a device body 1, the movable original platen table 2 is inclined at angles thetaA and thetaB in two directions, namely, the direction of an arrow A and the direction of an arrow B to a face orthogonal to an optical axis 9 and is held by leading out properly the other pieces 3b.
