<p><P>PROBLEM TO BE SOLVED: To make miniaturization and a high quality image compatible. <P>SOLUTION: Leaf springs 73 are installed in two places at both ends of a prism 78, pressing the prism 78 in a stopper 87 direction with pressing parts 86a, 86b. On the opposite side of the first and second leaf springs 73a, 73b holding the prism 78 in-between, there are installed the first and second stoppers 87a, 87b. Near the center of the prism 78, a projection 84 is protruding from a housing. The prism 78 oscillates around the projection 84 like a seesaw, with the illustrated upper position restricted by projections 81a, 81b provided in the leaf springs 73a, 73b, and with the lower position held by a cam 85, so that the prism 78 can be fixed with a certain inclination. To say the opposite, the inclination of the prism 78 can be adjusted by rotating the cam 85, making the inclination correctible even in the occurrence of a skew in an image. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
