PROBLEM TO BE SOLVED: To obtain an in-circuit tester for performing test by moving a probe pin based on an NC data in which a printed board can be tested in safety without requiring any manual confirmation of a test program by providing an improved mechanism for preventing interference of component. SOLUTION: A distance measuring sensor 2 having a mechanism being moved for scanning in the horizontal direction through an X-Y biaxial robot 3 is disposed above a printed board 1 fixed to a printed board guide block 7 and irregularities are detected on the entire surface of the printed board 1 through two-dimensional scanning of the sensor 2. A region mounted with a component is discriminated from a region mounted with no component based on a component mounting position data and presence of a component 10 mounted on the lowering track of a probe pin 5 is detected. Subsequently, a probe pin fixing unit 4 which does not interfere with the mounted component 10 is selected automatically for a test point 9 and a test is performed by lowering the probe pin 5. |
