<p>PURPOSE:To remove a malfunction due to the mixing of noises and the strain of a digital signal by forming a photoelectric conversion element corresponding to input/output pins for a logic IC into an IC socket. CONSTITUTION:A photoelectric conversion element 70 corresponding to an input/output pin 20 for a logic IC 10 is shaped into an IC socket 30. A digital electric signal from the IC 10 is transmitted over the element 70 from the pin 20, converted into the pulse signal of beams corresponding to the digital electric signal and sent to an optical fiber 60. On an input signal, the pulse signal of beams being transmitted from the fiber 60 is converted into a digital electric signal by the element 70, and sent into the IC 10 through the pin 20. Accordingly, a malfunction due to the mixing of noises and the strain of the digital signal is removed.</p> |
