MEASURING CIRCUIT, AND MEASURING APPARATUS USING SAME

PROBLEM TO BE SOLVED: To provide a measuring circuit capable of reducing a mounting area for an LSI, and capable of compactifying also an apparatus, and the measuring apparatus using the same. SOLUTION: The apparatus for measuring input energy of a radiation or the like is constituted of a detecting element group 19 for converting the input energy into an electric signal, an analog signal processing circuit 39 for short-wave-shaping the electric signal to generate a trigger signal of indicating that an input waveform exceeds a set threshold, and for holding a wave height value of a peak, an A/D converter 50 for converting the wave height value into a digital signal, and a digital signal processing circuit 79 for controlling the analog signal processing circuit 39 and the A/D converter 50, and for acquiring an input position and the wave height value to transmit data. The detecting element group 19 is formed into a micro strip type detecting element group with a detection range divided matrixlikely to output an X-axial detection signal 17 and a Y-axial detection signal 18 extended orthogonally each other, to reduce the number of input and output signal pins and the measuring circuits for the analog LSI and the digital LSI.
