摘要： A driving block includes a plurality of magnetic-field generating elements and a driving signal generating section, and the magnetic field generated by the plurality of magnetic-field generating elements is detected by a plurality of magnetic-field detecting elements. A shape calculating block calculates a shape of an insertion portion of an endoscope based on a frequency component corresponding to a frequency of the driving signal in a detection signal detected by the plurality of magnetic-field detecting elements. Oscillation frequency of the reference clock for deciding the frequency of the driving signal is changeably set by the frequency setting section, and the reference clock with oscillation frequency set by the frequency setting section is supplied to both of the driving block and the shape calculating block.

摘要： An inserting shape detecting probe has a long and slender core wire, a plurality of shape detecting devices, signal lines, and an outer sheath. The plurality of shape detecting devices extended from the signal lines are fixed to the core wire at a predetermined interval. The core wire is inserted in the outer sheath. The inserting shape detecting probe has a thermal radiating member which is arranged along the outer circumference of at least one of the shape detecting devices.
