Patent ID: 8717427

Claim:
An endoscope comprising: an insertion section including a bending section which is configured to bend in first perpendicular directions perpendicular to longitudinal directions and in second perpendicular directions perpendicular to the longitudinal directions and perpendicular to the first perpendicular directions; a grip section which includes a grip casing, and which is provided to a proximal direction side of the insertion section; a bending operation knob which is attached to the grip casing, and which is configured to input a bending operation of the bending section in the first perpendicular directions; a touch surface which is exposed in an outer surface of the grip casing, and on which a bending operation of the bending section in the second perpendicular directions is input; a positional information calculator which is configured to calculate a positional information of a touched region with time, the touched region being a region that is touched in an input of the bending operation in the second perpendicular directions on the touch surface; a positional change detector which is configured to detect, in accordance with the positional information of the touched region with the time, a positional change of the touched region when the bending operation of the bending section in the second perpendicular directions is input; a drive member which is configured to be driven to bend the bending section in the second perpendicular directions; and a drive controller which is configured to control a drive state of the drive member in accordance with the positional change of the touched region.
