PURPOSE:To make a complicated processing circuit unnecessary by arranging the arrangement of light receiving points on each real image so that it can be divided with a part or all of these real images in respect of the number of the light receiving points or the positions of the light receiving points or both of them. CONSTITUTION:A signal inputted from a signal input terminal 10 passes through a luminous element drive circuit 11-4 and a luminous element 3, and is radiated to space as signal light, and is transmitted to four pieces of channels. After the signal light is converted into an electric signal by a corresponding light receiving element on each real image 3 to 6, it passes through an amplifier 12-2, 12-4, 12-6, 12-8, and is outputted to a signal output terminal 14-1 to 14-4. One of the luminous elements 1-1, 1-2, 1-4 can be made selectively to emit light by the signal through a control terminal 8, a route select signal input terminal 9, and a route select switch 7. The signal is distributed in conformity to a distribution pattern determined beforehand by the positions of the luminous element to be made to emit the light and the light receiving element. |
