- FIG. 19 is a diagram showing an example in which a hook hole is provided on the side opposite to the side where the connector 31B of the operation / rotation drive unit 3B is provided.
- the side of the operation / rotation drive unit 3B where the connector 31B is provided is the same as that shown in FIG.
- two hook holes 57 installation direction defining means, installation means
- the operation / rotation drive unit 3B is used in a state in which the hook 59 provided with the shaft portion and the tip ball portion projecting from the installation arm 58 is hung on these hook holes 57.
- a configuration as shown in FIG. 19 is desirable. This is because the circular hole portion into which the tip sphere portion of the hook 59 is fitted is on the lower side in the gravity direction, and the vertically long hole portion on which the shaft portion of the hook 59 slides is on the upper side in the gravity direction.
- the partition 43 and the partition receiving recess 33B are used to provide drip-proofing or waterproofing.
- a configuration (not shown) may be adopted in which the electrical connection portions 36B, 46 are in a watertight structure at the time of connection.
- the partition 43 is provided with the full width of the base 42 and the partition receiving recess 33B is provided with the full width of the base 32 so as to provide a waterproof effect. Even if it is not provided to the full width, it is possible to achieve a certain degree of drip-proof effect.
- the operation / rotation drive unit 3B is provided with the connector 31B.
- the air / water supply tube 24, the channel 25, and the signal cable 26 are connected together.
- a similar connector 31B may be provided in the operation section 4.
- connection portions including the electrical connection portion and the fluid system connection portion can be connected in one action. Therefore, it is possible to reduce complications at the time of connection and more reliably prevent forgetting to connect.
- partition and the partition receiving recess are provided to the full width of the base so that the electrical connection side and the fluid system connection part are separated from each other in a watertight manner during fitting, it is possible to more reliably prevent the damage. Drops and a waterproof effect can be achieved.
- each of the above-described embodiments takes a signal cape as an example of a rotary self-propelled endoscope device.
- a connector for connecting a fluid line is described, other general endoscopes can be similarly applied.
