Abstract:
1. An endoscope light source apparatus, comprising: a turret provided to be rotatable about a predetermined axis, and provided with a first optical filter and a second optical filter for transmitting an illuminating light on a circumference of the rotation; an instruction section in which an operation instruction is inputted, the operation instruction being for locating and stopping the first optical filter or the second optical filter provided to the turret on an optical path of the illuminating light; a drive section that rotationally drives the turret; a first detector that detects a rotation angle of the turret and outputs a detection signal according to a result of the detection; a first detected portion for identifying a position of the first optical filter; a second detected portion for identifying a position of the second optical filter; a second detector that optically detects a position of the first or the second detected portion; and a turret control section that outputs a drive signal to the drive section to move the turret until the first or the second detected portion is detected by the second detector in order to position the optical filter designated in response to an input of the instruction section, after moving the turret so that a value of the detection signal detected by the first detector falls within a range set in advance, in response to the input of the instruction section, and stop the turret in response to the first or the second detected portion being detected.
