- the optical device can be easily attached to and detached from the eyepiece 3.
- the fixing mechanism using the eyepiece mounting holder is not limited to the one shown in the figure, but may be any mechanism that can be arbitrarily fixed and released.
- the eyepiece portion 3 can cope with the difference in the outer diameter.
- the difference in diameter can be handled by the above-described mechanism for moving the gripping member 48 in the radial direction.For example, since the outer diameter of the eyepiece of various optical devices currently on the market is about 28 to 42 mm as described above, What is necessary is just to set the amount of movement of the gripping member 48 in the radial direction so as to correspond to them.
- the eyepiece portion 3 having a smaller diameter in the case of the eyepiece portion 3 having a smaller diameter, as shown in FIG. 13, it has a C-shape when viewed from the axial direction, and the axial length corresponds to the gripping member 48.
- This can be achieved by using an ultra-small diameter adapter 51 formed according to the length.

It is possible to switch between direct observation of the equipment with the naked eye and imaging using a camera or imaging device. As a result, coupling and centering (optical axis alignment) can be performed at the same time as in the case of the knotnet type coupling in the illustrated example. State can be easily reproduced.
- an aperture mechanism is provided on the camera side of the taking lens 13.
- This aperture mechanism may be one that forms an opening (aperture) of any size in the center of the optical axis by using a plurality of commercially available general aperture blades 52 that need not have a special structure.
- each of the aperture blades 52 is pivotally supported by the lens support 14 in a swingable manner, and the aperture blade 52 is supported in the axial direction (optical axis) by an aperture blade holder 53.

Also, an axial groove 55a is provided on the inner peripheral surface of the aperture interlocking ring 55, and a lead pin 54a projecting radially and outwardly on the outer peripheral surface of the aperture blade ring 54 is formed by the axial groove 55a. It is guided in the direction. Thus, when the taking lens 13 is moved in the optical axis direction, the aperture blade 52 and the opening / closing mechanism thereof can be moved together with the taking lens 13.
- the eyepiece 3 is positioned at a position where the cushioning member 58 contacts the eyepiece 3 with the taking lens 13 positioned at a predetermined position (rotating position of the cam barrel 15 at a predetermined mark position).
- the aperture interlocking ring 55 is rotated, and the aperture leaf ring 54 is engaged with the axial groove 55a and the lead pin 54a. Also rotates. Since the lead pin 52a moves in the circumferential direction by the rotation of the diaphragm blade ring 54, the diaphragm blade 52 rotates about the pivotal support position with respect to the lens support 14.
- the opening area of the aperture formed by each aperture blade 52 can be changed according to the amount of rotation. For the aperture, for example, it is good to be able to set the f-number 1:32 or 1:44, which is the smallest f-stop that is more than the minimum f-stop 1:16 or 1:22 usually used in general cameras. . On the open side of the aperture, the ratio is set to 1: 3.5 of the photographing lens 13 described in the illustrated example.
- the distance from the shooting lens 13 to the subject is about 2 OOmm. It becomes possible to shoot at a very close distance. In the case of such a close-up shooting, the depth of field becomes extremely shallow, so that it is not used in a normal shooting environment to increase the depth of field.
- an iris for example, by setting the iris with the F value of 1:44 described above by turning the iris switching frame 56 and shooting a moving subject, use the camera 5 side to compensate for the extreme lack of light due to the extreme aperture. Use to flash the flash and shoot.
- shooting can be performed only when the flash is fired, so the peak time of the strobe flash acts as a substitute for the shutter speed, which provides an instantaneous shutter effect and causes the subject to move violently. You can take a picture in the state where it was done.
- the aperture When the aperture is set to a very dark aperture as described above, it becomes very dark in the viewfinder of the single-lens reflex camera, and it becomes difficult to set conditions using the viewfinder. In this case, the aperture should be wide open to set the conditions under a bright image, and when it is time to take the picture, the picture should be taken with the small aperture as described above. Note that the background of the photographed subject may be dark due to the limited reach of the strobe light. If you want to prevent this and the subject is an immovable object, you can shoot with a slow shutter speed without using a flash.
- the eyepiece mounting holder 41 in this example is not limited to the optical adapter 4 coupled to the camera in the illustrated example, but is also applicable to the corresponding part of the above-described imaging device 31 provided with the CCD 32. Is what is done. In this case, the mounting procedure for the eyepiece 3 and the effects thereof are the same as those described above.
- a non-net type mechanism is shown as a detachable mechanism between the eyepiece mounting holder 41 and the photographing lens 13 (the lens barrels 43 and 44), but the mechanism is not limited to the bayonet type. It goes without saying that any other structure may be used as long as it is a detachable mechanism having the above convenience. By doing so, it is possible to use the eyepiece mounting holder 45 as a common one for the lens barrel for the camera and the lens barrel provided with the CCD, in addition to the good handling for the above-mentioned difference in the imaging mode. In addition, it is possible to perform imaging by appropriately reconnecting according to imaging by a camera or a CCD, so that the cost as an optical adapter corresponding to both can be reduced.
