[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a common mirror that can be used as a magnifying glass and a binocular stereoscopic mirror.

[0002]

[Prior Art]

 Conventionally, a common mirror that can be used as a magnifying glass and a binocular telescope is known, but a magnifying glass and a binocular stereoscopic observation mirror (an observation object such as an insect is restrained in a transparent hollow rotating body for magnifying observation with a binocular). There is no common mirror that can be used as a stereoscopic mirror).

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a common mirror which can be commonly used as a magnifying glass and the above-mentioned binocular stereoscopic mirror.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a central frame hole and front side frame holes, and a pair of left and right reflector mirror pivot parts and a loupe pivot part are provided on both middle and front ends of the upper and lower flanges. There is a frame and a radiation compartment for containing an object to be observed such as an insect, and at least one radiation compartment is located in the central frame hole of the frame so that rotation can be stopped at a position facing the front side frame holes of the frame body. A circular transparent hollow rotating body that is pivotally supported in the frame, and a pair of left and right opening and closing pivotally supported by the loupe pivotal support portion of the frame body so as to open in the frame body left-right direction and close in the frame body extension direction. When using a lens frame and a convex lens for magnifying observation fitted in the lens frame, and the magnifying glass with the lens frame closed in the extension direction of the frame body, the lens frame is closed at both front frame hole closing positions when using the lens frame. When using a binocular stereoscopic mirror opened to the left and right of the frame There was a structure comprising a said frame body of a reflecting mirror pivot portion to the pivoted left and right pair of reflecting mirrors to allow release to open with the opening angle of the lens optical axis approximately 45 degrees of the lens frame by.

[0005]

[Action]

 In the common mirror having the above-mentioned configuration, the pair of left and right reflecting mirrors are closed at the positions where the front and rear frame holes of the frame body are closed, and the pair of left and right lens frames in which the convex lenses are fitted are closed in the frame body extension direction. It can be used as magnifying glass to magnify and observe insects on the ground with two compound convex lenses.

An object to be observed such as an insect is placed in a radiation chamber of a transparent hollow rotator, and a pair of left and right lens frames having convex lenses fitted therein are arranged in the left-right direction of the frame body (perpendicular to the length direction of the frame body). Direction) and the left and right reflecting mirrors are opened so that the left and right reflecting mirrors have an opening angle of about 45 degrees with the lens optical axis. By stopping the rotation at all positions, it is possible to use it as a stereoscopic observation mirror for magnifying and observing an observation object such as an insect restrained in the compartment of the rotating body with the binocular through the convex lens.

【Example】

 An embodiment of the present invention will be specifically described below with reference to the drawings.

In the figure, reference numeral 1 is a synthetic resin frame body formed by butt-joining a pair of left and right frame body bodies 2 and 3, and this frame body 1 has a horizontally elongated central frame hole 4 and front side both sides. It has open square frame holes 5a and 5b, upper and lower flanges 6 and 6 and a thread tail projecting portion 7, and a pair of left and right small holes are formed on both sides of the middle of the upper and lower flanges 6 and 6. Mirror pivotally supporting portions 6a and 6b are provided, and loupe pivotally supporting portions 8a and 8b formed of a pair of left and right projecting pins are provided at both front end sides of the upper and lower flanges 6 and 6, respectively.

Reference numeral 10 is a circular transparent synthetic resin hollow rotor having a plurality of radiation compartments 11 for accommodating an object M to be observed such as an insect. The circular transparent case 12 and the rotating plate 13 that has a through hole 13a that can open and close the radiation compartment 10 and that is rotatably fitted to the side opening of the case 12 are provided. One radiation compartment 11 containing the object M is fitted into the frame central frame hole 4 so as to be able to stop rotation at a position facing the frame front both side frame holes 5a, 5b, and is centered with respect to the frame 1. It is pivotally supported by the protruding shaft 10a.

Numerals 14 and 15 can be opened in the loupe pivotal support portions 8 a and 8 b of the frame body 1 in the lateral direction of the frame body (direction orthogonal to the length direction of the frame body 1) and can be closed in the extension direction of the front side of the frame body 1. A pair of left and right open / close lens frames that are pin-supported so that they can face each other, and convex lenses 16 and 17 for magnifying observation are fitted into the lens frames 14 and 15, respectively.

Reference numerals 18 and 19 denote a pair of left and right reflecting mirrors which are supported by the reflecting mirror pivotally supporting portions 6a and 6b of the frame 1 so as to be openable and closable, and the reflecting mirror frames extend the lens frames 14 and 15 in the frame extending direction. When using the magnifying glass which is closed to face each other, the lens frames 14 and 15 are opened to the left and right of the frame body at the closed positions of the frame front side frame holes 5a and 5b as shown by the imaginary line in FIG. When the binocular stereoscopic observation mirror is used, it is pivoted so that it can be opened as shown by the solid line in FIG. 1 with an opening angle θ of about 45 degrees with the lens optical axis P of the lens frames 14 and 15.

Thus, the common mirror having the above-described structure is such that the pair of left and right reflecting mirrors 18 and 19 are closed at the positions where the front and rear frame holes 5a and 5b of the frame body are closed, and the left and right pair of convex lenses 16 and 17 are fitted. If the lens frames 14 and 15 are closed in the extension direction of the frame body as shown by the imaginary line in FIG. Can be used as

An object to be observed M such as an insect is put in the radiation compartment 11 of the rotating body 10, the lens frames 14 and 15 are opened in the left and right direction of the frame body, and a pair of left and right reflecting mirrors 18 and 19 are provided. In the state shown by the solid line in FIG. 1, which is opened so as to form an opening angle θ of about 45 degrees with the lens optical axis P, the rotor 10 faces the frame both side frame holes 5a and 5b in the insect compartment 11. It can be used as a stereoscopic observation mirror for enlarging and observing an observation object M such as an insect restrained in the compartment 11 of the rotating body 10 with the binocular through the convex lenses 16 and 17 by stopping the rotation to a position where .
