As for the second endoscope 2B and the first endoscope 2A, in addition to the above, for example, when the first endoscope is used as a spare for the second endoscope, the second endoscope The case where the endoscope 2B is made long and the first endoscope 2A is made short, or the case where the endoscope 2B has a treatment instrument insertion port and the case where the endoscope 2A does not have the case.

That is, the first endoscope 2A and the second endoscope 2B have different types of internals such as the length of the insertion portion and the presence / absence of a treatment instrument insertion port, in addition to the case where the diameter of the insertion portion 11 is different. A combination of endoscopes is conceivable.
The user inserts the insertion portion 11 of the second endoscope 2B housed in the upper side of the housing case 6 into an inspection object, for example, the inside of a jet engine, etc., and whether there is a damaged portion or the like inside the object. Check for no.
However, when the insertion portion 11 has an insertion hole that cannot be inserted into the inspection target, there is a case where the inspection cannot be continued smoothly with one type of endoscope.
Assuming such a case, in this embodiment, it is desirable to store the first endoscope 2A having a diameter smaller than that of the second endoscope 2B in the same storage case 6. .

Next, the insertion portion 11 of the first endoscope 2A or the second endoscope 2B has the same size as shown in FIG. 2 or FIG. It can be wound on a usable drum 16.
FIG. 11 shows how the insertion portion 11 is wound and held (fixed) on the drum 16.
The drum 16 is formed of a hard member, for example, a resin hard member, and has a cylindrical (or annular) shape provided with a hollow portion 16c as shown in FIG. A winding portion 16a that can be wound is provided, and a flange portion 16b that protrudes radially outward from the winding portion 16a is formed on both sides thereof, and the insertion portion 11 that is wound around the winding portion 16a (this It is regulated so that it does not come off from the winding part 16a.
