Abstract: <P>PROBLEM TO BE SOLVED: To provide an electric flexible endoscope system that enables a bending operation of a bending section after an understanding of a given bent state of the bending section.  <P>SOLUTION: A bending wire 24 has mark portions 24a arrayed in line in given positions when the bending portion 23 is in a non-flexed state. When the mark portions 24a are arrayed in line in the given positions, an optical sensor 35 detects it. An control section 30 has a trackball 36 with an electromagnetic brake 36a. The electromagnetic brake 36a is operated ON/OFF according to a detection signal output from the optical sensor 35. When the optical sensor 35 detects an array of the mark portions 24a in the given positions, the optical sensor 35 outputs a detection signal. Urging force of the electromagnetic brake 36a is then canceled for a moment to reduce rotational resistance on the trackball 36 and thereby notify an operator of the non-flexed state of the bending portion 23.  <P>COPYRIGHT: (C)2003,JPO
