Abstract
PURPOSE: To simplify the construction of the circuit by providing an inspection circuit commonly used in items to be inspected and comparing each piece of information in normal states memorized beforehand individually for the items to be inspected with the results of the inspection.
CONSTITUTION: The contact 3 of a pass selection relay PSR is closed by a drive timing signal from a control part 10, and, at the same time, the transistor Q of a drive circuit 1 is turned on to excite a switch magnet 4. At this time, when the transistor is in normal state, -48V is supplied from a drive line 2 to an inspection circuit 9 via a protective circuit 6, and when the transistor Q is in off-state, the ground becomes an input of the circuit 9 via magnet 4, contact 3, drive line 2 and a circuit 6. Accordingly, at the time of on-state inspection, when the circuit 1 operate normally, the inspection output signal A becomes an "L" level. If the memorized information pieces of the items to be on-state-inspected are in "L" levels, the values obtained by the comparison coincide to each other, and therefore it is determined that the result of the inspection is satisfactory. By these procedures, the construction of the circuit can be simplified.
