摘要： In an endoscope, a curvature indicating element for curvature-indicating a curvable curvature section provided adjacent to a distal end of an elongated inserting section having elasticity is arranged at a location close to a thumb of a hand grasped by an operator in the operating section provided at a proximal end portion of an inserting section. An operating element for controlling operation of fluid such as outflow, inflow or the like is arranged at location opposite to the curvature indicating element in the operating section. Thus, operations of the curvature operation, outflow and inflow of the fluid and the like can be executed simultaneously under a condition where the operating section is grasped.

摘要： An endoscope apparatus according to the present invention includes a warping velocity control device which receives an angle of warp detected by an angle detection device and a value of an electric current realized at this angle of warp and detected by an electric current detection device. The control device makes comparisons between the angle of warp and the value of the electric current and data about a normal state stored in a storage device. If the result is larger than data for the normal state by a predetermined value, the warping velocity is lowered while a discrimination is made that an abnormal state (the warp-enabled portion has come in contact with the body wall) takes place. Additionally, the apparatus could include a time detecting device for detecting a time in which an electric quantity supplied to a drive means is larger than a predetermined time. The warping velocity control device controls the warping velocity according to the comparison made by the time detecting device.
