[Claims]
[Claim 1]
An elastic tubular body is arranged at the tip of the insertion portion, and a plurality of pressure chambers are arranged along the circumferential direction on the tube wall of the elastic tubular body, and the elastic tubular body is selectively pressurized to pressurize the elastic tubular body. It has a curved part that bends the body in a predetermined direction,
In an endoscope device provided with a fluid supply unit including a syringe connected to a fluid supply pipeline for supplying a pressurized fluid to the pressurizing chamber and a piston slidable inside the syringe.
A driving means for electrically operating the piston of the fluid supply unit, and
A control means for controlling the drive means and
And
The control means is provided with a bending operation stop control function that stops the sliding operation of the piston with respect to the syringe and slides the piston by reversing the sliding operation direction when an instruction to stop the bending operation of the bending portion is input. An endoscopic device characterized by.
2.
An input means which is connected to the control means and performs an operation of bending the curved portion is provided.
The endoscope device according to claim 1, wherein the input means is operated to control the piston according to a tilt angle and a tilt speed of the input means.
3.
The endoscope device according to claim 2, wherein the control means sets an output corresponding to the tilt angle and the tilt speed at a drive frequency.
4.
The endoscope device according to claim 2, wherein the control means sets an output corresponding to the tilt angle and the tilt speed with a voltage.
5.
The endoscope device according to claim 1, wherein the speed of the piston is set to be substantially the same as the speed when the curvature is increased and when the curvature is decreased, or the speed when the curvature is decreased is set to be slow.
