Abstract
An electric bending endoscope includes a temperature sensor that detects the temperature of a motor as a state value indicating the driving state of a bending drive unit. A bending control device comprises: a temperature detection unit that receives the data of the temperature detected by the temperature sensor; a record unit in which the limits of motor temperature inputted in advance are recorded; a comparison unit that compares the data of the temperature sent from the temperature detection unit with the limits of motor temperature recorded in the record unit; and a notification unit that notifies that the driving state of a motor is approaching the limit.

22. An electric bending endoscope, comprising:
-
an elongated insertion unit;
a bending section formed adjacent to a distal section of the insertion unit;
a bending drive unit for driving the bending section to bend;
a bending operation unit for outputting a bending instruction signal for driving the bending drive unit in response to an operation by an operator;
an operation state detection unit for detecting a state signal that changes depending on an operation state of the bending operation unit;
a record unit in which a threshold value to be compared with the state signal is recorded;
a comparison unit for comparing the state signal with the threshold value; and
a control unit for restricting, on the basis of a result of comparison by the comparison unit, a bending operation of the bending section based on the bending instruction signal outputted by the bending operation unit. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
