PURPOSE:To obtain an interface which needs no change despite the function improvement of a device by reading directly and optically the information on the screen of a display provided in the device and transmitting said information to an information processor. CONSTITUTION:The production information on a producer of IC is collected by a control part 1 to be displayed at a CPT display part 2 in the form of the visual information as well as to be received optically by a photodetector 3 via a route 21. The output received by a photoelectric transducer is shaped into a binary waveform through a waveform shaping circuit 5 and supplied to an information processor via an interface circuit 6. Thus no change is required at all to an interface part as long as the production information is displayed at a CRT display part although the function of the producer of IC is improved owing to the technical advancement of a produced IC. |
