In the following, the front side in the figure is referred to as the front, and the rear side is referred to as the rear.
As shown in FIG. 2, the front panel 13 formed on the front surface of the light source device 10 has an output connector 11 that grips the outer periphery of one end of the light guide 3 when the light guide connector 3 a is connected to the light source device 10. It is arranged. Further, in the front panel 13, in the vicinity of the output connector 11, a connection index (see FIG. 3) of the rotating member 17 described later is displayed, so that, for example, the type or manufacturer of the connected endoscope is displayed. An indicator hole 14 which is a display means composed of an opening for display is formed. Further, in the vicinity of the index hole 14 in the front panel 13, a rotation knob 52 for rotating the rotation member 17 is disposed.

  A rotating member 17 is disposed inside the light source device 10 facing the front panel 13, specifically, at a position facing the output connector 11 and the index hole 14, and faces the front panel 13 of the light source device 10. A selective rotation member 12, which is a selective rotation means having a rotation center connected to the rotation knob 52, is disposed in the interior, specifically, at a position facing the rotation knob 52.
