Abstract: A controller is configured to control an operation of a self-propelled mechanism provided in an elongated insertion section of an endoscope. The controller includes a circuit configured to: acquire a speed value corresponding to a rotation speed of a motor of the self-propelled mechanism; acquire a torque value corresponding to a torque generated by the motor; control rotation of the motor by switching between at least two of speed control that controls rotation of the motor based on the speed value and torque control that controls rotation of the motor based on the torque value; and stop the rotation of the motor if the torque value has exceeded a predetermined threshold value, perform the torque control when the rotation of the motor is resumed.

Abstract: A control apparatus controls an operation of a self-propelled mechanism of an endoscope. The control apparatus includes a drive circuit that outputs a motor current, a motor current detection circuit that acquires a value relating to magnitude of the motor current as a detection value, a storage circuit that stores a limit value relating to the detection value, and a control circuit that performs an operation as a first controller that controls the drive circuit so as to stop the motor when it is determined that the detection value exceeds a value relating to the limit value, and performs an operation as a second controller that controls the drive circuit so as to stop the motor when it is determined that the detection value exceeds the value relating to the limit value.

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.
