IPC: H01H19/00
Filed: 2008-02-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a switch device which is superior in durability and can detect precisely rotation direction and rotation amount of a rotation operating member without using a mechanical switch member.  <P>SOLUTION: When a winding core is rotated, a shading wheel 10 is rotated corresponding to its rotating direction and rotating amount, and accompanied with this rotation, light transmission parts 20 installed at prescribed places of the shading wheel 10 move rotating to correspond to a light detection part. When light from a light-emitting element of this light detection part transmits the light transmission part 20 of the shading wheel 10 and is received by the light receiving element 22, the receiving amount of light by the light receiving element 22 is changed by a long hole 23 of the ring receiver 17 corresponding to rotating direction and rotating amount of the shading wheel 10. Thereby, the rotation direction and rotation amount of the winding core can be detected precisely and a mechanical switch member such as a switch spring as shown in a foregoing reference is not required for use, and a switch device with superior durability can be provided.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a spotlight which has a high fixture efficiency and in which light collection and diffusion can be carried out using a sheet of plano-convex lens.  <P>SOLUTION: A turtleback pattern 20 is installed having turtleback 21 in which a radius of curvature is different on a backside 15a of a plano-convex lens 15.
