The above mentioned tip body 132 is provided on the outer periphery of the tip with a male screw part 132 to which a sensor adapter 137 is to be screwed. The above mentioned sensor adapter 137 is provided with an inserting hole 137a for inserting the fiber scope 2 in case the sensor adapter 137 is fitted to the sensor sheath 131 and a sensor housing hole 137b. Any one sensor 138, for example, among a temperature sensor, humidity sensor, pressure sensor, gas (O.sub.2, CO.sub.2) sensor, radioactivity sensor and microphone is provided within the sensor housing hole 137. The above mentioned sensor 138 is connected to an electric contact 139 provided on the sheath side end surface of the adapter 137 so that, in case the adapter 137 is fitted to the sheath 131, the electric contact 139 will be connected to the above mentioned signal connector 133.
Further, a temperature measuring resistor, thermocouple, thermistor, semiconductor type and quartz crystal type are used for the above mentioned temperature sensor. A thermistor type, lithium chloride type, ceramic type, resistance type high molecular weight membrane type, capacity type high molecular weight type and crystal type are used for the humidity sensor. The pressure sensor is of a semiconductor type or piezoelectric device type. Further, the gas sensor is of a metal oxide semiconductor type, anion adsorptive oxidative gas (oxygen, nitrogen, oxide), cation adsorptive reductive gas (H.sub.2, CO, CH, alcohol), iron oxide semiconductor type (town gas), zirconia type (oxygen) or galvanic type (oxygen). The radioactivity sensor is of a gas input counting tube, semiconductor type or scintillation type.
The diameter D.sub.1 of the above mentioned insertable part 220 is set, for example, at 9.5 mm., the length L in the lengthwise direction of the above mentioned receptacle is set, for example, at 50 mm. and the outside diameter D.sub.2 of the above mentioned large diameter part 221 is set, for example, at 13 mm. When the outside diameter D.sub.2 of the above mentioned large diameter part 221 is made 13 mm., even with such lamp (light source) of a large bright point as a halogen lamp or metal halide lamp, the above mentioned light guide will be able to efficiently guide the illuminating light in.
In case the inside diameter of the discriminating part 213a of the above mentioned receptacle 209a and the outside diameter of the discriminating part 223a of the connector 17a are represented by d.sub.1, the inside diameter of the discriminating part 213b of the above mentioned receptacle 209b and the outside diameter of the discriminating part 223b of the connector 17b are represented by d.sub.2 and the inside diameter of the discriminating part 213c of the above mentioned receptacle 209c and the outside diameter of the discriminating part 223c of the connector 17c are represented by d.sub.3, the relation of d.sub.1, d.sub.2 and d.sub.3 will be d.sub.1 &lt;d.sub.2 &lt;d.sub.3.
The intensity of the radiation heat by the light source of the light source apparatus is represented by the reference numerals of the receptacles 209 to be 209a&gt;209b&gt;209c and the heat durability of the light guide inserted through the light source connector 17 is represented by the reference numerals of the connectors 17 to be 17a&gt;17b&gt;17c.
In the discriminating part 213 of the receptacle 209 in FIGS. 46 to 48, the length (depth) L in the lengthwise direction is different in response to the intensity, for example, of the radiation heat of the light source. Likewise, in the discriminating part 223 of the connector 17, the length L in the lengthwise direction is different in response, for example, to the heat durability of the light guide inserted through the connector 17. A regulating part 324 is provided at the rear end of this discriminating part 223. In case the length of the discriminating part 213a of the above mentioned receptacle 209a and the length of the discriminating part 223a of the connector 17a are represented by L.sub.1, the length of the discriminating part 213b of the above mentioned receptacle 209b and the length of the discriminating part 223b of the connector 17b are represented by L.sub.2 and the length of the discriminating part 213c of the above mentioned receptacle 209c and the length of the discriminating part 223c of the connector 17c are represented by L.sub.3, the relation of L.sub.1, L.sub.2 and L.sub.3 will be L.sub.1 &gt;L.sub.2 &gt;L.sub.3.
