なっている。On the other hand, the operation section 3 is provided with a switching valve 23 as a switching means, interposed between the air supply pipe 7 and the liquid supply pipe 8 at a midway portion. That is, the air supply pipe line 7 and the liquid supply pipe line 8 are divided by the switching valve 23 into an upstream side 7 a and a downstream side 7 b, 8 b. The switching valve 23 includes a cylinder 24 with one end open, and a piston 26 that is slidably accommodated in the cylinder 24 and biased in the projecting direction by a spring 25. This piston 26 has a through hole 27 that is sufficiently larger in diameter than the air supply pipe line 7 that penetrates in the radial direction, an outer circumferential groove 28 extending over the entire length of the outer circumferential surface below the through hole 27, and A leak hole 29 is formed which communicates with the hole 27 and has the other end opened at the upper end surface of the piston 26 protruding from the cylinder 24 . The piston 26 is normally located in the state shown in FIG. 8a and the downstream side. Therefore, the leak hole 29
By blocking the compressed air with a finger, the compressed air generated by the air pump 11 is prevented from flowing out into the atmosphere, and therefore flows to the downstream side 7b. Moreover, if the operator closes the +7-hole 29 with his finger and pushes the piston 26, the upstream side 7a and the downstream side of the air supply pipe line 7 can be separated. b is maintained in a communicating state through the through hole 22, and the upstream side 8a and downstream side 8b of the liquid feeding pipe line 8 communicate with each other via the outer circumferential groove 28. When the upstream side 8a and downstream side 8b of the liquid feeding pipe 8 are communicated, the cleaning liquid 15 in the tank 16 whose liquid level is pressed by the compressed air generated by the liquid feeding pump 19 becomes the first liquid feeding aid. The liquid flows from the pipe 14 through the liquid feeding pipe line 8 . That is, by operating the switching valve 23, the upstream side 7m+8a and the downstream side 'ib, 8b of the air supply pipe 7 and the liquid supply pipe 8 can be brought into communication at the same time.

ノズル６から嵜者の体腔内へ噴出する。Next, the operation of the endoscope device having the above structure will be explained. When inserting the insertion section 2 of the endoscope 1 into the patient's body cavity with the light source device 4 turned on and supplying air from the nozzle 6, the leak hole formed in the piston 26 of the switching valve 23 29 is covered by the operator's finger. Then, the compressed air that had been generated by the air pump 11 and released into the atmosphere from the upstream side of the air pipe 7 through the leak hole 27 of the piston 26 is released into the air pipe 7. Since it flows to the downstream side 7b, the compressed air is ejected into the body cavity of the person from the nozzle 6 with which the downstream side 1b communicates.

ない。Next, when cleaning the objective lens by spraying a mixture of air and cleaning liquid 15 through the nozzle 6, the operator closes the leak hole 29 of the piston 26 with his finger.
6 into the cylinder 24 against the restoring force of the spring 25. Then, the upstream side 7a and the downstream side 1b of the air supply pipe line 7 are maintained in a communicating state through the through hole 27, and the upstream side 8a and the downstream side 8b of the liquid supply pipe line 8 are connected to the piston 26.
The two communicate with each other via an outer circumferential groove 28 formed in the outer peripheral groove 28 . Liquid feed pipe line 8
When the upstream side 8 sl and the downstream side 8 b of After passing through the upstream side 8a and flowing downstream &bK, it flows into the downstream side 7b of the air supply pipe line 7. Therefore, the compressed air from the air pump 11 flowing through the air line 7 at the downstream end 7b of the air line 7 is mixed with the cleaning liquid 15, and is ejected from the nozzle 6 toward the objective lens. Clean the lens. In such a cleaning operation, the cleaning liquid 15 is pressurized by the liquid feeding den f19 which is activated at the same time as the switch '1k of the light source device 4 is turned on, and the upstream side 8a of the liquid feeding pipe line 8 is filled with the cleaning liquid 15. In other words, since the cleaning liquid 15 has reached the switching valve 23 of the operating section 3, if this switching valve 23 is operated, the cleaning liquid 15
5 and compressed air can be ejected from the nozzle 6 in a short time. By changing the head, the mixed fluid can be sprayed from the nozzle 6 with good response by operating the switching valve 23. In addition, since the air supply pipe 7, liquid supply pipe 8, and K are connected to the air supply pump 11 and the liquid supply pump 19, respectively, the flow resistance of the liquid supply pipe 8 may be caused by some reason. Even if the amount of air is increased, it will not be difficult to pressurize the liquid feeding pipe line 8, and the amount of liquid fed will decrease, and the amount of air fed will not increase.
