## Abstract

An introducing device system includes: an insertion portion; a bending portion which is provided at the insertion portion; an operation portion through which an input operation is performed for bending the bending portion; a pulling member connected to the bending portion and pulled in accordance with the operation through the operation portion; a detection section that detects a moving state of the pulling member; a driving unit that rotationally drives; a driving force transmitting unit including an inner circumferential surface configured to be able to contact an outer circumferential surface of the driving unit, and an outer circumference on which the pulling member is wound, the driving force transmitting unit being reduced in diameter in accordance with pulling of the pulling member; and a driving unit control section controls the driving unit when the moving state detected by the detection section is different from a state determined in advance.

## Claims

### Claim 1

An introducing device system comprising:
an insertion portion configured to be inserted into a subject;
a bending portion which is provided at the insertion portion and configured to be bendable;
an operation portion through which an input operation is performed for bending the bending portion;
a pulling member connected to the bending portion and pulled in accordance with the input operation through the operation portion;
a detection section configured to detect a moving state of the pulling member that moves in accordance with the input operation;
a driving unit that rotationally drives;
a driving force transmitting unit including an inner circumferential surface configured to be able to contact an outer circumferential surface of the driving unit, and an outer circumference on which the pulling member is wound, the driving force transmitting unit being reduced in diameter in accordance with pulling of the pulling member; and
a driving unit control section configured to perform control for increasing a rotational speed of the driving unit when the moving state detected by the detection section is different from a state determined in advance.

### Claim 2 (depends on 1)

The introducing device system according to claim 1, wherein the detection section detects a moving speed of the pulling member, and
the driving unit control section performs control for increasing the rotational speed of the driving unit when the moving speed detected by the detection section is faster than a moving speed determined in advance.

### Claim 3 (depends on 2)

The introducing device system according to claim 2, wherein the detection section includes an operation speed calculation section that calculates a speed of the input operation performed through the operation portion by detecting the moving speed of the pulling member.

### Claim 4 (depends on 1)

The introducing device system according to claim 1, wherein the detection section is a motor current increase rate detection section that calculates an increase rate per unit time of a current value of the driving unit.

### Claim 5 (depends on 1)

The introducing device system according to claim 1, wherein the driving force transmitting unit has a slit and formed in a C-shape.
