PROBLEM TO BE SOLVED: To provide a portable type projector installation base on which a projector can be installed simply by being placed thereon, and which is excellent in assembly, has a compact shape, and is convenient to carry or store. SOLUTION: The portable type projector installation base is composed of a combination of three support levers 2 forming the three sides of projector installation face S of a triangular shape and three legs 5 of a rod shape. When rings 22 and 23 at the ends of the support levers 2 are fitted on the upper ends of the legs so as to permit play and then the legs 5 are inclined, the upper ends of the legs 5 engage with the rings 22 and 23 so that the rings 22 and 23 are fixed on the legs 5. A recess and projection 54 and 26 are formed to position each ring 22 and the support face 53 of the corresponding leg 5 in a circumferential direction. COPYRIGHT: (C)2007,JPO&INPIT
