2. The holding device according to claim 1, wherein the holder restricts movement of the endoscope and/or the insertion auxiliary member.

3. The holding device according to claim 1, wherein the holder holds the endoscope and/or the insertion auxiliary member movably in an insertion direction of the insertion portion of the endoscope.

4. The holding device according to claim 3, wherein the holder is capable of securing the endoscope and/or the insertion auxiliary member at any position in the insertion direction of the insertion portion of the endoscope.

5. The holding device according to claim 1, wherein the holder holds the endoscope and/or the insertion auxiliary member movably in a direction other than the insertion direction of the insertion portion of the endoscope.

6. The holding device according to claim 5, wherein the holder is capable of securing the endoscope and/or the insertion auxiliary member at any position in the direction other than the insertion direction of the insertion portion of the endoscope.

7. The holding device according to claim 3, further comprising a driving device which moves the holder.

8. The holding device according to claim 7, further comprising a control device which controls the driving device so as to move the holder in the insertion direction of the insertion portion of the endoscope.

9. The holding device according to claim 7, further comprising a control device which controls the driving device so as to move the holder in the direction other than the insertion direction of the insertion portion of the endoscope.

10. The holding device according to claim 1, further comprising an insertion length measurement device which measures an insertion length of the insertion portion of the endoscope and/or the insertion auxiliary member.

11. The holding device according to claim 1, further comprising a load measurement device which measures a load generated when the endoscope and/or the insertion auxiliary member is moved.

12. The holding device according to claim 11, further comprising a safety device that is actuated based on a measurement value of the load measurement device.

13. The holding device according to claim 1, wherein the holder comprises an endoscope holder which holds the endoscope and an auxiliary member holder which holds the insertion auxiliary member, and an extendable cover which prevents a splash of a body fluid from a body cavity is mounted in a surrounding manner at least between the endoscope holder and the auxiliary member holder.

14. The holding device according to claim 1, further comprising a securing device which secures the holder to a different member.

15. The holding device according to claim 1, wherein an expandable balloon is mounted to a tip of the insertion portion of the endoscope and/or a tip of the insertion auxiliary member.

16. An endoscopic device, comprising:

an endoscope having an expandable first balloon at a tip of an insertion portion; and

an insertion auxiliary member that is placed over the insertion portion of the endoscope to help insertion of the insertion portion and has a second balloon at a tip of the insertion auxiliary member,

wherein the endoscopic device further comprises a holding device according to claim 1 which holds the endoscope and/or the insertion auxiliary member.

17. An operating method of an endoscopic device comprising an endoscope and an insertion auxiliary member that is placed over an insertion portion of the endoscope to help insertion of the insertion portion,

wherein at least one of the endoscope and the insertion auxiliary member is held by a holding device.

18. An operating method of an endoscopic device for inserting, into a tubular body cavity, an endoscope having an expandable first balloon at a tip of an insertion portion, and an insertion auxiliary member that is placed over the insertion portion of the endoscope to help insertion of the insertion portion and has an expandable second balloon at a tip of the insertion auxiliary member, successively comprising the steps of:

inserting the insertion portion and the insertion auxiliary member into the tubular body cavity with the first balloon and the second balloon being contracted, and then expanding the second balloon to secure the insertion auxiliary member in the tubular body cavity;

inserting the insertion portion into a deeper part of the tubular body cavity with the guide of the insertion auxiliary member;

expanding the first balloon to secure the insertion portion in the tubular body cavity;

contracting the second balloon to insert the insertion auxiliary member with the guide of the insertion portion;

expanding the second balloon to secure the insertion auxiliary member in the tubular body cavity; and

drawing the insertion auxiliary member together with the insertion portion with the insertion auxiliary member being secured in the tubular body cavity,

wherein at least one of the endoscope and the insertion auxiliary member is held by a holding device in each step.

19. An operating method of an endoscopic device for inserting, into a tubular body cavity, an endoscope having an expandable first balloon at a tip of an insertion portion, and an insertion auxiliary member that is placed over the insertion portion of the endoscope to help insertion of the insertion portion and has an expandable second balloon at a tip of the insertion auxiliary member,
