Description

[Detailed explanation of the invention] This invention is a dual-purpose magnifying perspective scope that can also be used as a telescope. The purpose is to create a telescope-type magnifying scope with a completely new structure that can be used as both a telescope and a magnifying scope. Our goal is to provide the following.

That is, the magnifying perspective scope of this invention has a hood mounting opening on the lower side of one end, a viewing port on the upper surface of the other end, and a viewing hole for the viewing scope on the lower side located directly below the viewing hole. A lens barrel with a window hole formed therein, a translucent hood that is fitted and fixed to the hood mounting opening of this lens barrel, and an objective that is placed and fixed inside the hood mounting opening of the lens barrel. A reflector that reflects incident light from the side toward the other end of the lens barrel, and a reflector that is arranged and fixed between the viewing port and the projection scope window hole at the other end of the lens barrel to reflect the reflected light from the reflector. A half mirror that can be seen downward to reflect the light in the direction of the viewing port, a fixed magnifying convex lens installed between the half mirror and the reflecting mirror in the lens barrel, and a window hole for a viewing scope inside the lens barrel. The shutter frame is provided to be able to slide open and close by operation, and the shutter frame is held in an upper frame portion that can move forward and backward between the viewing port and the half mirror, and in combination with the above-mentioned convex lens constitutes a telescope lens system. The gist of the present invention is a magnifying transmission scope that is equipped with a concave lens and can also be used as a telescope.

An embodiment of this invention will be described below with reference to the drawings. In the drawing, 1 has a hood stand mounting opening 2 on the lower side of one end, and a peephole 4 on the upper surface of the other end that is closed by an end wall 3. This is a lens barrel in which a window hole 5 for a transmission scope is formed in the lower side portion located directly below this viewing port 4, and this lens barrel is made of a plastic lens barrel half body 1.
It is constructed by combining and joining A and 1B as shown in FIG. Reference numeral 6 denotes a hood mount that is fitted and fixed to the hood mount attachment opening 2 of the lens barrel 1, and is molded from plastic as a translucent truncated pyramid. Reference numeral 7 denotes a reflecting mirror placed and fixed inside the hood mounting opening 2 of the lens barrel 1, which bends the incident light P1 from the object side at right angles and directs it toward the other end of the lens barrel (in the direction of the end wall 3). The insert pieces 10a, 10b, 10 are arranged at an angle of inclination of 45 degrees with respect to the axis of the incident light P1 so that the incident light P1 can be reflected.
It is inserted and fixed between a' and 10b'.

Reference numeral 8 denotes a half mirror arranged and fixed inside the other end of the lens barrel 1 (between the viewing port 4 and the transmission scope window hole 5), which bends the reflected light beam P2 from the reflecting mirror 7 at right angles and allows viewing. The lens barrel half body 1A has an inclination angle parallel to the reflecting mirror 7 so that it can be reflected in the direction of the mouth 4 and can also be seen downward.
It is inserted and fixed in a cantilevered manner into the inwardly protruding groove 10c of the side wall as shown in FIG.

9 is a half mirror 8 and a reflecting mirror 7 inside the lens barrel 1.
a fixed magnifying convex lens incorporated between 11
is a shutter frame provided in the lens barrel 1 so that the window hole 5 for the transmission scope can be slid open and closed;
and a guide side plate having a slide operation knob 13 projecting outward through the horizontally elongated slide groove 12 of the lens barrel half body 1B and slidingly guided along the inner surface protrusion 14 of the lens barrel half body 1B. 11b, and an upper frame portion 11c extending from the upper end of the guide side plate portion 11b in the direction of the shutter plate portion 11a. A concave lens 15 is held in the upper frame portion 11c which can move forward and backward within 8 seconds. This concave lens 1
Reference numeral 5 denotes a telescope lens system that is combined with a convex lens 9 for magnification when the shutter frame 11 is moved as shown in Figure 3, and forms a telescope lens system. It is offset from the mouth 4 as shown in FIG. In addition, 16 in the figure shows a transparent plate for dustproofing fitted into the hole of the above-mentioned viewing port 4.

FIG. 1 shows the state in which it is used as a magnifying perspective scope with the shutter frame 11 open. In this state, an image of a drawing placed under the hood stand 6 is reflected on the reflector 7; The captured image is magnified by the convex lens 9 and reflected on the half mirror 8, and the image reflected on the half mirror 8 can be seen from above the viewing port 4. In this case, the image seen from above is reflected on the half mirror 8. As a result, the image appears directly below the dotted line in Figure 1, so while looking at the image, you can copy the enlarged image with a pencil or the like on a blank sheet of paper placed below it.

FIG. 3 shows a state in which the shutter frame 11 is used as a telescope with the projection scope window hole 5 closed by moving it to the right side in FIG. The held concave lens 15 matches the viewing port 4, and the convex lens 9
In combination with this, a telescope lens system is constructed, so it can be conveniently used as a Galilean-style telescope.

Since this idea is as described above,
It is possible to provide a telescope-type magnifying perspective scope with a completely new structure, which can be used as both a telescope and a magnifying perspective scope by simply switching the shutter frame.
