（Ｂ）。When the viewing device 7 is connected to the eyepiece 6 of the endoscope 1 as shown in FIG. 2, the solenoid 24 is electrically connected to the control circuit. Therefore, when the control circuit is activated and a rectangular wave-shaped intermittent drive current is supplied to the solenoid 24, the drive rod 23 moves and moves the mirror 2 to the child side position (solid line position) and the observation position (dotted line position). position) as each end. This state is shown by (A) in FIG. When the mirror 21 is located on the slave side, the observation light from the endoscope 1 is not split (the amount of light is reflected toward the second imaging lens 17 on the slave side, and The light is transmitted to the secondary eyepiece 11 through the second imaging lens J7 and the image guide fiber 18, and observation using the full amount of light is possible from this secondary eyepiece I). On the other hand, mirror 2
When the endoscope 1 is in the observation position, the observation light from the endoscope 1 is not blocked by the mirror 21, and the entire amount of light advances directly toward the observation eyepiece 16. Observation using the entire amount of light can be performed from this observation eyepiece 9. Further, the observation light is alternately sent to the secondary eyepiece 1 and the observation eyepiece 9 at short intervals (preferably, the frequency of interruption of the observation light image is 24 times/second or more) to make the most of the afterimage. Figure 3 (B).

It is desirable to move one drive rod 23. and,
When taking a photograph using the photographing device 12, its shutter is opened as shown in the middle of FIG. 3, and the sum of the amounts of light actually incident on the observation eyepiece 9 side becomes the exposure amount.

The frame 36 is slidably guided by a cavity 37 formed in the viewing device main body 8. Furthermore, the frame 36 holding the triangular prism 35 is provided with a drive rod 39 which is loosely inserted into a solenoid 38 as a drive means, and when driven in the same manner as in the previous embodiment, the triangular prism 35 is moved at short intervals. It is designed to be moved back and forth.

As shown in the figure, all of the observation light from the endoscope 1 is sent to the child side and can be observed through the child side eyepiece 11. In addition, when the triangular prism 35 is retracted from the optical path as shown by the dotted line in FIG. It can be observed at.

その他については前記実施例と同様である。Other aspects are the same as those in the previous embodiment.

A control circuit may be used to control the solenoids 24 and 38 to continue operating so that the prism 35 is always located at the observation position. In other words, by doing this, the observation light is continuously sent only to observation from the start to the completion of the release, as shown in FIG. 6, so it is possible to shorten the shutter time and obtain clearer photographs.

This embodiment uses a triangular prism 41 as the optical path switching means, and this triangular prism 41 is attached to the circumference of a frame 42 that rotates in a plane perpendicular to the optical axis of the first imaging lens 15. The movement is effected by rotation of the frame 42. That is, the frame 42 is rotatably attached to the viewing device main body 8, and is driven to rotate by a motor 43, which is also provided in the viewing device main body 8. Further, as shown in FIG. 8, two triangular prisms 41 are provided for the frame 42. Furthermore, the frame 42 is provided with a through hole 44 . Each of the above triangular prisms 41.4
1 and the through hole 44 are arranged on concentric circles. Also,
The triangular prisms 41, 41 are provided at angular intervals of 90°, and the through holes 44 are formed over the width of the 90° angular intervals. As the frame 42 rotates, the triangular prisms 41, 41 and the through holes 44 are positioned in the optical path, so that the triangular prisms 41 and 41 are positioned in the optical path as shown in FIG.
．． 41 is in the optical path, it reflects all the observation light from the endoscope 1 and sends it to the second imaging lens 17 on the child side, and then transmits it to the child eyepiece I through the image guide fiber 18. Further, when the through hole 44 is located in the optical path, all the observation light from the endoscope 1 passes through the observation eyepiece 9.
send to. Thus, bright observation light is alternately transmitted to the observation eyepiece 9 and the secondary eyepiece 11. Other points are the same as in the above embodiment.
