Abstract

PURPOSE: To obtain a thickness setting device which enables the setting of the thickness of a reference plate easily and at a high accuracy by obtaining a specified thickness from the number of layers thereof when the reference plate formed like a tape is wound.
CONSTITUTION: In calibration, with a calibration command signal C, a sample 13 is taken out of the measuring area and an arithmetic control circuit 17 transmits a control signal to turn a frame rotating shaft by 90° from the measuring position with a driver 19 detecting the rotating position. At the same time, a signal is transmitted to the circuit 17. The signal allows an X-ray beam 12a to transmits a tape-shaped reference plate 14 wound on a measuring reel 20c and enter a detector 15. The output thereof is converted into a thickness signal with a signal processing circuit 16 and calibrates X rays absorption characteristic with an arithemic control circuit 17. Then, the circuit 17 transmits a control signal to the driver 19 to turn the rotating shaft 20b by 90° while the sample 13 is inserted. The X-ray beam 12a passes through a through-hole 20g and the sample 13 and enters the detector 15. According to the output of the detector, the control circuit 17 transmits the thickness signal SA calibrated thereby enabling setting of the thickness for the reference plate 14 at a high accuracy.
