出装置。[Claims for Utility Model Registration] 1. A prism is arranged on one side and a light-emitting element and a light-receiving element on the other side, sandwiching the transparent part for detection of the member to be detected, and the light emitted from the light-emitting element is In the position detecting means in which light passes through the transparent part for detection and the prism to reach the light receiving element, the light emitted from the light emitting element and the prism pass through the transparent part for detection and the light emitted from the light emitting element is transmitted to the same transparent part for detection. A position detection device characterized in that the light emitting element, the light receiving element, and the prism are arranged so that reflected light from the light emitting element passes through the prism. 2 Utility Model Registration A position detection device according to claim 1, characterized in that the light beam emitted from the light emitting element and the light beam incident on the light receiving element are substantially parallel to each other. 3 Utility Model Registration Scope of the Claims 1. The position detection device according to claim 1, wherein the light beam emitted from the light emitting element and the light beam incident on the light receiving element are made non-parallel. 4 Utility Model Registration The device according to any one of claims 1 to 3, characterized in that the light-emitting element and the light-receiving element are arranged on one printed wiring board. Detection device. 5 Utility Model Registration The device according to claim 1 or 2, characterized in that the device is configured such that the light beam emitted from the light emitting element and traveling through the prism becomes a substantially parallel light beam. Device. 6 Utility Model Registration Scope of Claims In the device according to any one of claims 1 to 5, the light emitting element and the light receiving element are arranged in one housing having means for attaching to the printed wiring board. A position detection device characterized in that it is incorporated in the form of an integrated unit.
