摘要： PURPOSE:To realize an optical keyboard which is immune from noise and static electricity, etc., in which many optical switches can be arranged densely and immoderate bending is not applied to an optical fiber, and also, which is thin in thickness by placing the optical fiber of the optical switch and a light shielding piece at the side of an operator, and also, near the outside of a housing. CONSTITUTION:A light shielding piece 19 is provided projectingly as one body on the side face of an operator 13 so as to go in between end faces of optical fibers 15A, 15B. The light shielding piece 19 is formed so that a thick wall part 19a of thickness which goes into a gap of end faces of sleeves 16A, 16B is provided on the base part side, and a thin wall part 19b which has decreased wall thickness from both faces is provided on its tip. This light shielding piece 19 is constituted so that when the operator 13 is moved up and down, the thin wall part 19b passes through between the end faces of the optical fibers 15A, 15B, and the thick wall part 19a does not go in between the end faces of the optical fibers 15A, 15B but passes through between the end faces of the sleeves 16A, 16B. In such a way, a countermeasure for noise and static electricity can be executed, and even if the optical switches are arranged densely, no immoderate bending is applied to the optical fiber at the time of drawing out the optical fiber, and also, the keyboard can be formed thinly.

摘要： PURPOSE:To facilitate initial checking or the like during no operation of a shape-memory spring by using a strong spring part and a weak spring part to form contacts with the shape-memory spring serving as an actuator. CONSTITUTION:Contacts 4, 5 fixed to face each other in a contact housing 2 are shaped in similar figures, and an opposite contact 6 is supported in between. The contact 4 is structured to connect a strong spring part 4E on a tip of a weak spring part 4D. The strong spring part 4E is supported on a shape-memory spring 10 through an insulator 11. The shape-memory spring 10 is not actuated at initial connection and the opposite contact 6 is supported with small supporting strength on the weak spring part 4D and so initial checking or the like is easily performed. When the connection causes a temperature to attain to a prescribed value, the shape-memory spring 10 is operated to generate a prescribed value of supporting strength through the strong spring part 4E.

摘要： PURPOSE:To utilize a mounting technique used for a normal plane substrate for the mounting of an electronic part as it is by mounting the electronic part onto a printed wiring film and conducting molding with a resin. CONSTITUTION:An electronic part 14 is mounted to a printed wiring film 11 having flexibility and a circuit body 15 is prepared, the circuit body 15 is set up onto the inner surface of a mold 16 so that a part mounting surface is directed toward the inside of a cavity 19, the inside of molds 16, 18 are filled with a resin 21 and molded with the resin, and a resin molded from 22 and the circuit body 15 are unified. That is, the part is mounted at the step of the printed wiring film 11, thus applying a mounting technique used for a normal plane substrate as it is.

摘要： PURPOSE:To prevent malfunction by making it possible to make an optical path on/off without using electricity and providing a clearance between an optical path switching piece and an operation button. CONSTITUTION:An optical path switching piece 6 forms an opening 5 that passes light, and parts in which a hole, a groove etc. are not formed are made to an intercepting part 4 that does not transmit light. The optical path switching piece 6 is incorporated in a groove 3, and when an operation button 4 is depressed, the switching piece is pushed down and the opening 5 is positioned on the optic axial line of the optical path 2, and the optical path 2 becomes the state of passing light. An elastic push up device 9 is formed of a spring and placed on an optical circuit substrate 1. It pushes up an operation button 8 and forms a clearance 10 between the button 8 and the switching piece 6. Thereby, a highly reliable switching device for optical circuit that does not operate even when the button 8 is touched by mistake, and operates surely only when regular operation of the button is made.
