Abstract

PURPOSE:To improve the inspection efficiency of an X-ray fluoroscopic apparatus, by storing desired images in a plurality of picture memories, and continuously displaying the pictures displayed on video monitors for a period of time corresponding to the multiple of the number of the monitors. CONSTITUTION:A welded steel pipe 10 is carried at a given speed by means of carrying rollers 11. Through the weld of the steel pipe 10, a fluorescent multipliction tube 14 is arranged facing to an X-ray generator 13 arranged inside the steel pipe 10. The optical images converted by the multiplication tube 14 are picked up by means of a TV camera 15, and the video signals are supplied to a plurality of picture memories A, B and C by means of a camera controller 16. The video recording instruction signal is generated by means of the output from a length-measuring apparatus 18 which corresponds to the moving distance of the steel pipe 10. The pictures stored in the respective picture memories A, B and C are displayed on video monitors A', B' and C' unitl the contents of the respective memories are rewritten. Thereby, the decision time can be made a plural number times as long as conventional methods. Accordingly, accurate decision results can be obtained.
