Abstract

PURPOSE: To arrange so that the characteristics test may be conducted simply and promptly by outputting the characteristic signal from the electronic equipment and inputting the characteristics test signal to a following stage through a photocoupler.
CONSTITUTION: In conducting the test, at first, a switch operating signal is inputted to a terminal 16-1. Then a transistor 16-2 is in ON position and a luminous element 16-3 emits light, opening a switch 15-1. Due to the output of a circuit 11, a transistor 15-3 is turned on, causing a luminous elements 15-4 to emit light. As a result, characteristic signal is obtained at terminals 16-8, 16-9. If characteristics test signal is input from a terminal 16-5, a transistor 16-6 is in ON position, causing a luminous element 16-7 to give forth light. Consequently, the test signal is added to a circuit 12.
