Claims

[Scope of utility model registration request]

The outer case formed in a cylindrical shape includes at least a first cylindrical case having an opening in a circumferential body portion, and the first cylindrical case.
and a second cylindrical case that is screwed together with the cylindrical case, and a light emitting element, a light receiving element, and a push button switch are installed inside the outer case and electrically connected to the light emitting and receiving element. a circuit board mounted on the push button switch and an operation button projecting into the opening, the light emitting element emits reflected light from the light emitting element to an external medium, and the light receiving element reflects the light emitted from the light emitting element to an external medium. In an optical reading device that receives light, a pair of pivot parts are provided near the threaded portions of the first and second cylindrical cases, and the outer wall surface of the pivot part of the cylindrical case on the male thread side and the cylindrical part on the female thread side are provided. An optical reading device characterized in that an inner wall surface of a pivot portion of a case is rotatably fitted.
