PURPOSE:To execute display which has completely coincided with a control state, by using an optical pulse being a signal medium, as it is for the display. CONSTITUTION:A gate circuit 7 generates an output signal (b) in accordance with an input signal (a). The signal (b) is set at t1 time, is reset at t2 time, is sent to a driver 8, amplified, and is sent to a light emission element 4. The element generates an optical pulse by emitting light only when the signal (b) has been applied. This pulse and the signal (b) are almost synchronized. A part of said pulse is sent to a display part 9, and its residual part is sent to an optical fiber 5. A transmission pulse of the fiber 5 is made incident to a photodetecting element 10, is converted photoelectrically, its waveform is shaped, and it is applied to a switching circuit 13. The input signal to the circuit 13 is almost synchronized. The circuit 13 electrically connects a driving electric power source 14 to an object to be driven 15. In this way, synchronizing with the signal (b) of the circuit 7, the body 15 is driven. |
