PURPOSE:To allow the miniaturization of a hologram element and to reduce the electric power consumption of a device by dividing one signal by utilizing the diffraction of the hologram element. CONSTITUTION:An information input device converts the electric signal inputted from one input terminal to a light signal and outputs the light signal. The hologram element 2 disposed on the optical axis of the information input device diffracts the incident light signal of the hologram element 2 to a matrix shape. Photoelectric conversion elements 3 receive each of the many light signale emitted in the form of the matrix from the hologram element 2 and the output terminals connected to the respective photoelectric conversion elements 3 output the respective electric signals. The division of the electric signals to many signals and the parallel transfer thereof are, therefore, executed by connecting a piece of the electronic apparatus which outputs the electric signal to the information input device and connecting the output terminals 9 to the many electronic apparatus. The element is miniaturized in this way and further, the electric power consumption of the device is reduced. |
