Abstract: A display apparatus for a living body insertable apparatus includes an inserting unit configured to be inserted into a living body, and a power unit configured to generate a propulsive force for the inserting unit in the living body. The display apparatus includes a driving force detector, a display calculator, and a display controller. The driving force detector acquires a value relating to a driving force of the power unit. The display calculator determines a display area of a gauge configured to have the display area varying according to the driving force, based on the value. The display controller outputs a signal to display the gauge on a display device.

Abstract: An apparatus includes a rotation body, a motor, a drive controller, a rotating speed detector, a rotation error determination circuit, and a filter. The rotation body is provided on an outer peripheral surface of an elongated insertion section and configured to be rotatable around a longitudinal axis. The motor rotates the rotation body. The drive controller controls driving of the motor. The rotating speed detector detects a rotating speed of the motor based on an encoder signal output from an encoder. The rotation error determination circuit determines an error in rotation of the rotation body based on the detected rotating speed. The filter passes, as the encoder signal, only a signal having a frequency, outside a frequency band of a high-frequency signal of a high-frequency treatment instrument, of signals input to the rotating speed detector.

Abstract: A controller which controls an operation of a self-propelled mechanism of an endoscope includes an inspection control section, a usual control section, an endoscope connection detection circuit and a control switch section. The endoscope connection detection circuit detects that the endoscope has been connected. The control switch section determines whether or not the inspection operation is performed for the endoscope at the time of the connection of the endoscope, causes the usual control section to perform the usual operation when the inspection operation is performed, and causes the inspection control section to perform the inspection operation and then causes the usual control section to perform the usual operation when the inspection operation is not performed.

Abstract: An insertion apparatus includes an insertion section, a rotational housing, a motor, and a controller. The motor rotates the rotational housing. The controller designates a rotational direction of the motor. The controller limits the rotational direction of the motor to allow the insertion section to move only in a removal direction when inspection control for inspecting an operation relative to an insertion direction of the insertion section is initiated.
