Conventionally, the recording of images obtained by the TV monitor attached to the above-mentioned electronic scope and fiberscope is
This is carried out using a monitor image photographing device which has a built-in TV monitor provided separately from the TV'U monitor and can take photographs by remote control while the viewer watches the V monitor.

Generally, when taking pictures using a monitor image capturing device, 35m x 1m pictures are used for diagnosis and archival purposes, and instant pictures are used as sketches or at other hospitals.

Photographs are changed depending on the purpose, such as for introduction to other departments.

When it is desired to take photographs of different types of cameras, such as a 35g+m reflex camera or an instant camera, the cameras are alternately attached to one monitor image photographing device and shadows are taken.

However, when performing endoscopic observation, when taking pictures of the same part with different cameras, or when taking pictures of different parts with different cameras, cameras must be replaced frequently. For this reason, the replacement operation is troublesome and the replacement time is long, which hinders rapid inspection.

Furthermore, Japanese Utility Model Application Publication No. 62-58448 discloses a technology that allows the release of a camera attached to a monitor image capturing device to operate only when the TV monitor built into the device is turned on. has been done.

[Objective of the Invention] The present invention has been made in view of the above-mentioned circumstances, and is an internal vision system that allows the same monitor image to be taken by different types of cameras and that allows camera selection operations to be performed easily and quickly. The purpose is to provide a mirror system.

[Means for Solving the Problems] The endoscope system of the present invention is capable of connecting a plurality of monitor image photographing devices, and is equipped with a control means capable of outputting a control signal for transport to the monitor image VA shadow device. It is something.

[Operation 1] In the present invention, a plurality of monitor images @Odoshousou δ are connected to the control means. Photographing of the plurality of monitor image photographing devices is controlled by the 1IItIl signal from the control means.
