The figure shows a multiple configuration of the present invention, in which the same light is sent to a light transmitting fiber and a light receiving fiber is installed in a light receiving section corresponding to each switch section. FIG. 3 shows a multiple configuration of the present invention, in which transmitting and receiving optical fibers are integrated, through which light of different wavelengths flows, and it is possible to read which wavelength of light is blocked.
Figure 4 shows an application of this invention to a numeric keypad. 1 is a light transmitting section, 2 is a light receiving section, 3 is a light shielding section,
The arrow is light.
