In recent years, in order to improve the operability of bending the endoscope,
An endoscope device has been proposed in which a motor drives a bending mechanism coupled to an insertion section. However, if the operator does not accurately grasp the curvature angle of the insertion tube, the insertion tube may be curved more than necessary inside the body cavity, causing the tip to come into contact with the inner wall of the body cavity, and in the worst case, damage the body cavity or damage the body cavity. There is a risk of cutting. For this reason, conventionally, as disclosed in Utility Model Application Publication No. 53-45790, for example, a member that is mechanically displaced in accordance with the curvature angle of the insertion portion is provided in a region close to the motor drive control member, and this displacement causes It was configured to notify the endoscope operator of the bending angle. However, the provision of the above-mentioned members has the disadvantage that the structure of the endoscope main body becomes complicated and the manufacturing cost increases.

The operation of one embodiment configured in this way will be explained. Now, the operating lever 28 is shown at 94 in FIG.
When tilted in the direction of the arrow shown, the rotating frame 32
is also pushed by the operating lever 28 and rotates in the direction of arrow 94. At this time, the sliding contact of the potentiometer 46 also moves toward the terminal 46c in accordance with the amount of operation of the rotating frame 32, so the terminal voltage V 1 of the intermediate terminal shown in FIG. 3 increases, It becomes higher than the terminal voltage V 2 of the intermediate terminal 22b of the potentiometer 22. As a result, a negative voltage is generated at the output terminal of the operational amplifier 78, the PNP transistor 86 becomes conductive, and a voltage proportional to the output voltage is supplied to the first motor 4, so that the motor 4 is driven to rotate.
As a result, for example, the drum body 8 rotates in the direction of the arrow indicated by reference numeral 96 in FIG.
is pulled in the direction of arrow 98. As a result, one end, for example, the end 14b of the wire 12 is pulled, and the curved portion 18 of the insertion portion 16 is curved downward. In this situation, since the sliding contact of the potentiometer 22 mounted on the drum body 8 of the first motor 4 also slides toward the terminal 22c side, the terminal voltage V 2 ( Figure 3) is also rising.

When the terminal voltage V 2 of the intermediate terminal 22b becomes substantially equivalent to the terminal voltage V 1 , the output voltage of the operational amplifier 78 becomes approximately OV, so that the PNP
The transistor 86 is cut off and the first motor 4 stops driving. In this way, the output voltage V 1 of the potentiometer 44 provided on the bending operation member 26
changes depending on the amount of operation of the operating lever 28, and during this time, the first motor 4 is also rotationally driven in accordance with the operating lever 28. At this time, potentiometer 22
is interlocked with the motor 4, and changes the output voltage V2 according to the amount of operation of the motor 4. And the above output voltage
As soon as the difference between V 1 and V 2 becomes zero, the motor 4 is stopped.

As described above, according to the embodiment, the amount of operation of the bending operation section 26 is controlled by the potentiometers 44, 46.
The operating amount of the drum bodies 8, 10, which are directly connected to the motors 4, 6, is electrically detected by the potentiometers 22, 24. Therefore, the overall structure of the endoscope can be significantly simplified, and its manufacturing cost can also be reduced. Furthermore, the potentiometers 44, 46 of the bending operation section 26 and the potentiometers 22, 2 of the first and second motors 4, 6
By electrically processing the respective output voltages of 4 with the servo control circuit 92 including the operational amplifier 78,
It is possible to determine the amount of operation of the first and second motors 4 and 6 that accurately follows the amount of operation set by the bending operation section 26. Therefore, the insertion section 16 of the endoscope
The bending motion of the can be controlled accurately without any time loss.
