Is locked to the conical rod 14 by.

A lens barrel receiving cylinder 131 is projectingly provided on the side surface of the head portion of the elevating rod 13, and a second fixing knob 132 is attached to the lens barrel receiving cylinder 131. The lens barrel receiving cylinder 131 receives the above-mentioned pivot 32 so that the pivot 32 can be freely inserted and removed, and the pivot 32 is attached by the second fixing knob 132.
Locked in.

Next, the optical system of the present embodiment will be described. In FIG. 3, the lens barrel 3 including the eyepiece barrel 31 and the cylindrical portion 33 is fitted to the objective lens barrel 112 on the swivel plate 11 to form a microscope barrel.

The objective lens barrel 112 includes a first objective lens 4 having a focal length of 55 mm.
Are arranged. A second objective lens 5 having a focal length of 55 mm is arranged in a cylindrical portion 33 forming the lower part of the lens barrel 3, and a plane mirror 6 is arranged in the upper part thereof. Furthermore, an eyepiece tube 31 having a focal length of 16.7 mm composed of field lenses 7a and 7b and an eyepiece lens 8 is arranged in an eyepiece tube 31 which is obliquely provided above the lens barrel 3.

Next, the operation of the telescope / microscope of the above embodiment will be described. First, the operation of the microscope will be described.

Then, as shown in FIG. 6, the second fixing knob 132 (second
(See the figure) slightly, the lens barrel 3 in the raised position is rotated 90 degrees around the pivot 32 (see FIG. 2), and the second fixing knob 132 is tightened again.

As shown in FIG. 7, the state in which the telescope / microscope of the present embodiment is used as a gantry-mounted telescope causes the lens barrel 3 to rotate about 90 ° or less around the pivot 32 (not shown) so that the lens barrel 3 can be moved. Have a certain angle of attack.

The above-mentioned vertical telescope is mainly used indoors, but when the telescope / microscope of this embodiment is desired to be used outdoors,
The second fixing knob 132 that locks the pivot 32 of the lens barrel 3 with the lens barrel receiving barrel 131 provided on the side surface of the end of the elevating rod 13 is loosened, and the lens barrel 3 is separated from the main body 1 to carry the telescope. Can be used as

[Effect of device]

Since the present invention is constructed as described above, the stage of the microscope of the present invention can be rotated 360 degrees in the horizontal plane with respect to the pedestal. Since the illumination angle with respect to the object changes, not only the object to be observed can be observed accurately from all directions, but also the image of the object to be observed can be observed through the eyepiece lens in either an upright state or an inverted state. Therefore, it does not include a configuration in which an inversion prism for erecting an image is inserted into and removed from the optical path to invert the image,
The image of the object to be observed can be switched between the upright state and the inverted state with a simple configuration and at the minimum time and operation, and more accurate observation can be performed.

In addition, the microscope with a telescope of the present invention is used as a microscope, and by removing the lens barrel from the lens barrel receiving collar attached to the swivel, it can be used as a telescope with a base fixed to the main body. It is very convenient because it can be used for multiple purposes because it has a structure that can be used as a single portable telescope by separating it from the main body.
