断面高さ表示装置。[Claims for Utility Model Registration] (1) A counter that is connected to an encoder attached to the drive unit of the moving fulcrum, receives a rising or falling signal, and counts the absolute height based on the pulse signal from the encoder; a preset counter that counts as zero when a rising or falling signal is input and is preset at a certain arbitrary position; and a display device connected to the two counters via a display switching device; A cross-sectional height display device for an X-ray tomography apparatus comprising a preset counter and a preset switch connected to a display switching device. (2) The preset counter is a counter that counts pulse signals from the encoder, and is connected to the counter via a comparator, and receives a rising or falling signal of the moving fulcrum from an arbitrary position as a reference, with the rising side being +, 2. The cross-section height display device for an X-ray tomography apparatus according to claim 1, further comprising means for counting the descending side as - and inputting the signal to a display switching device.
