Abstract

PURPOSE:To improve the productivity at the time of assembly by leading a reflected light to a light receiving element through an optical fiber, so that the reflected light is led surely to the light receiving element without executing a special alignment, etc. CONSTITUTION:A reference light which is radiated from a light emitting element 1 is converged by a lens 2 and radiated to a bar-code, and its reflected light is led to a light receiving element 5 through an optical fiber 3. Since the bar- code is linear, the convergence of the reference light radiated to the bar-code is not so important, and an alignment of the light emitting element 1 and the lens 2 can be easily executed. Also, the reflected light is directly made incident on the optical fiber, and also, one end face of the optical fiber 3 is provided so as to be adjacent to the bar-code, therefore, such an alignment as the case of using a light receiving lens is not required. In such a way, the productivity is improved.
