FIGS. 5 to 7 show a second embodiment of the present invention. FIG. 5 shows a schematic configuration of the entire system of the endoscope apparatus 110 according to the present embodiment. The endoscope apparatus 110 according to the present embodiment includes an endoscope 111 inserted into a body cavity of a patient, and an endoscope holder 112 having an articulated structure that movably holds the endoscope 111. ing.

Further, the endoscope 111 has an elongated insertion portion 1.

Next, the operation of the above configuration will be described.
In the present embodiment, the observation image of the endoscope 111 is the TV camera 1
15 and is displayed on the display monitor 138. FIG. 7 shows a visual field range R1 of an observation image displayed on the eyepiece unit 113 of the endoscope 111.

Here, the visual field range R2 of the observation image of the endoscope 111 captured by the CCD 116 via the zoom lens 117 of the TV camera 115 is smaller than the visual field range R1 of the eyepiece unit 113. And this CCD 116
The field of view R2 imaged by the display monitor 138
By moving the CCD 116 within the visual field range R1, the position of the visual field range R2 projected on the CCD 116 changes, and the visual field can be moved.

The size of the observation image projected on the CCD 116 can be changed by operating the zoom lens moving mechanism 119 of the TV camera 115 to move the zoom lens 117 forward and backward in the optical axis direction. That is, magnification / wide-angle observation can be performed. Furthermore, CC
The CCD moving mechanism 118 for moving the D116 is controlled by the visual field movement control device 124.

When the assistant is the switch 1 of the TV camera 115,
There is an effect that the visual field can be moved by operating 20 to 123.

FIG. 8 shows a third embodiment of the present invention. In the present embodiment, the configuration of the TV camera 115 of the second embodiment (see FIGS. 5 to 7) is changed as follows.

Is provided. Here, the rotation support unit 1
Switch 123 rotated by 41 and TV camera 1
Signal transmission to and from the internal circuit 15 is performed by a known slip ring (not shown).

Next, the operation of the above configuration will be described.

When operating the up / down / left / right visual field movement switch 123 provided on the casing exterior of the TV camera 115 of the embodiment, the positional relationship between the assistant and the TV camera 115 is determined as shown in FIG.
In the state shown in (A), the operation feeling of the moving direction of the visual field by the assistant matches the moving direction of the switch 123,
In the positional relationship shown in FIG. 9B, the operation feeling of the assistant in the moving direction of the visual field is shifted with respect to the moving direction of the switch 123. Therefore, in the positional relationship shown in FIG. 9B, the operation of the assistant to move the field of view in the target direction becomes complicated.

On the other hand, in this embodiment, the assistant and the TV
When the camera 115 and the camera 115 have the positional relationship shown in FIG. 9B, as shown in FIG.
By rotating the up / down / left / right view movement switch 123 with respect to the casing exterior of the TV camera 115 by 41, the state in which the operation feeling of the view movement direction by the assistant and the view movement direction assigned to the switch 123 are aligned. Can be matched correctly.

Therefore, in the TV camera 115 of the present embodiment having the above configuration, the up / down / left / right viewing movement switch 123 is set to the TV.
Since the rotation support portion 141 for rotatably supporting the casing exterior of the camera 115 is provided, even when the positional relationship between the operator such as an assistant and the TV force camera 115 changes variously, the vertical / horizontal view movement switch is provided. 123 is the rotation support unit 1
By rotating by the 41, it is possible to easily match the operational feeling of the moving direction of the visual field by the assistant with the moving direction of the visual field assigned to the switch 123. Therefore, even when the positional relationship between the operator such as an assistant and the TV power camera 115 changes variously, there is an effect that the operability of the view movement operation by the up / down / left / right view movement switch 123 can be maintained in a good state.
