PROBLEM TO BE SOLVED: To facilitate the modification of spraying conditions, such as spraying pressure of a fluid to be sprayed, the kind of the fluid to be sprayed, spraying pattern or the like, when spraying a fluid from a distal hard part of an insertion section. SOLUTION: A distal face of the distal hard part 2c has two spraying ports 32a and 33a. The spraying ports 32a and 33a form distal openings of first and second spray conduits 32 and 33 penetrating through the distal hard part 2c, and first and second fluid supply tubes 34 and 35 are connected to the spraying ports respectively. The first fluid supply tube 34 opens to a connecting port 36 of a main operating unit 1, and the second fluid supply tube 35 opens as a connecting port 37 formed at a connecting section 23 of a connector 17 of a universal cord 3. A manual fluid supplying means 40 or an automatic fluid supplying means 50 are connected detachably to the connecting ports 36 and 37. COPYRIGHT: (C)2009,JPO&INPIT
