Abstract

PURPOSE:To freely perform measurement without decreasing measuring speed and with a low cost in spite of the size of a printed board by moving either or both a matrix shape pin plate and a printed board to be measured. CONSTITUTION:At least one pin plate 6 is arranged in matrix shape in a prescribed area, and the measurement is performed by protruding a required pin and pressurizing contact with the significant part of the printed board as moving th pin plate 6 to the desired part of the printed board 1 to be measured. The substrate 20 of the matrix pin plate 6 is provided with a jogging part 24 at the lower part of a throughhole 22 through which a contact stylus 10 is pierced, and the contact stylus 10 and a movable part 14 are energized upward with a spring 26. Therefore, since the tip of the contact stylus 10 is abutted with a pattern 3 on the printed board 1 by supplying a force overcoming the energizing force of the spring 26 to the movable part 14, it is possible to recognize the normal/defective condition of a mounting component and a circuit by applying an electrical signal to a conductor 18 and judging the presence/absence of the detection of the electrical signal at a prescribed part.
