Claims

[Claims for Utility Model Registration] 1. A light transmitting means for projecting light onto an input side end face of an optical fiber and a light receiving means for receiving light from an output side end face of the optical fiber, selectively changing the optical path of the optical fiber. In an optical switch device that performs a switching operation by blocking, a substrate is provided having a movable elastically deformable tongue defined by a slit, and an optical fiber is fixed on the substrate in a state spanning the slit. At the same time, a cut surface is formed on the optical fiber by cutting it at a portion corresponding to the slit, and the optical fiber is cut in accordance with the displacement of the cut surface of the optical fiber due to the pressing operation of the movable tongue piece. An optical switch device characterized in that the optical switch device is configured such that the optical path of the switch is blocked. 2. A request for registration of a utility model characterized in that the light receiving means is constructed by disposing a photosensor film on a light receiving side substrate, and the output side end face of the optical fiber is bonded to the sensor film by thermal welding. The optical switch device according to the first item in the range.
