Abstract

PURPOSE: To obtain in a highly precise tracer head, by supporting a shaft having a stylus part with a floating body hanged within a frame through an elastic body via another elastic body and providing a horizontal direction displacement detector and a vertical direction displacement detector to the floating body and the shaft respectively.
CONSTITUTION: A floating body 16 is hanged from a fixed plate 15 fixed to a frame main body 14 via an elastic body (bar, plate or spring) 17, and a shaft 2 having a stylus 1 is supported within the body 16 via an elastic body 18. Cores 9 and 11 of differential transformers 8 and 10 are attached to the body 16, and a core 13 of a differential transformer 12 is attached. The stylus 1 senses the Z-direction displacement, the extent of displacement is detected by Z-axis displacement detectors 12 and 13. While the extents of X- and Y-direction displacement are detected by X- and Y- axis displacement detectors 8W11. In such way, a highly precise tracer head is obtained.
