Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a telescope that can be used as both a magnifying glass and a telescope.

[Conventional technology]

Conventionally, as a magnifying glass telescope as mentioned above,
A magnifying observation mirror disclosed in Japanese Utility Model Application No. 62-96547 is known, which is configured so that it can be switched between a magnifying glass and a telescope by reversing the reflecting mirror.

[The problem that the idea attempts to solve]

The conventional magnifying observation mirror described above is configured to magnify and observe an area to be observed placed on a transparent stage from both the front and back sides, and is capable of observing insects and the like on the ground as they are. It is impossible to adjust the focus of the telephoto lens when switching the telescope, and the observation mirror body has an L-shaped side surface with an upper peephole and a side peephole.
There were problems such as being bulky and inconvenient to store and carry.

The purpose of this invention is to provide a telescope that can also be used as a magnifying glass, which eliminates the above-mentioned conventional problems.

[Means to solve the problem]

In order to achieve the above object, the magnifying glass telescope of this invention has a concave cavity 2 whose upper and lower surfaces and rear end surfaces are open, and an upper surface 3 of the cavity 2 on the closed end side.
and a grip body 1 having a concave planar shape with a magnifying glass viewing window 6 opening into the cavity 2 and a telephoto viewing port 7 incorporating a telephoto eyepiece 8 in the front face portion 5; A lens barrel 10 incorporating a telephoto/loupe objective lens 12 stored in a horizontal state in a shaped cavity 2, and a lens barrel 10 that can be slid straight in the front and rear directions with respect to a grip body 1 and a viewing window for a magnifier. 6, the lens barrel 10 can be used in a telescope with the lens barrel 10 parallel to the gripper 1, The tube 10 is characterized in that it can be used as a magnifying glass in a state in which it is pushed down and rotated below the viewing window 6 for the magnifying glass.

[Effect]

In the magnifying glass telescope having the above configuration, the lens barrel 10 incorporating the telephoto/loupe objective lens 12 is held in the grip body 1.
It can be used for a telescope when placed in a horizontal position.In this case, hold the gripper 1 with one hand, for example the left hand, and hold the lens barrel 10 with the other hand, for example the right hand, and place the telephoto viewing port 7 on your eye. The lens barrel 10 is held by the gripping body 1
By horizontally moving the telescope lenses 8 and 12 in the front and rear directions, the telescope lenses 8 and 12 can be adjusted for distance and distance. Further, if the lens barrel 10 is pushed down and rotated by hand below the magnifying glass viewing window 6 while stored in the gripper 1, the lens barrel 10 is tilted to the magnifying glass use angle θ with respect to the gripper 1. It becomes possible to use a magnifying glass to look through the magnifying glass viewing window 6 and observe insects on the ground under magnification.

〔Example〕

An embodiment of this invention will be described in detail below with reference to the drawings. In the figure, reference numeral 1 denotes a concave planar gripping body made of a combination of upper and lower halves 1a and 1b molded from synthetic resin. The front surface 5 formed by the upper surface 3 on the closed end side of the cavity 2 and the groove-fitting front end plate 4 has a viewing window 6 for a magnifying glass which opens into the cavity 2 as shown in FIG. A telephoto viewing port 7 is provided, and a telephoto eyepiece 8 made of a concave lens is mounted inside the telephoto viewing port 7 with a short cylindrical lens holder 9.
It is held in place and assembled as shown in FIG.

Reference numeral 10 denotes a rectangular lens barrel that is horizontally stored in the concave cavity 2 of the gripper 1, and is held by a lens holding frame 11 fitted into the rear end opening of the lens barrel 10. A telephoto/loupe objective lens 12 made of a rectangular convex lens is incorporated. Reference numeral 13 denotes a slide that supports the lens barrel 10 so that it can slide straight in the front-rear direction with respect to the gripper 1 and can be rotated downward to the magnifying glass use angle θ (for example, about 60 degrees) below the viewing window 6 for the magnifying glass. This slide rotation support means 13 includes a lens barrel sliding elongated hole 14 formed in the left and right side walls of the gripper concave cavity 2 in the front-rear direction;
15, a parallel elliptical protrusion 16 and a circular protrusion 17 that protrude from the center position in the height direction of the left side surface of the front end of the lens barrel 10 and slide into the sliding slot 14;
A rectangular protrusion 18 that slides into engagement with the swing elongated hole 15 protruding from the center position in the height direction of the right side surface of the front end of the lens barrel 10, and a notch formed on the lens barrel housing end side of the slide elongate hole 14. a circular groove 14a that allows the circular protrusion 17 to rotate downward; a circular hole 14b that allows the parallel elliptical protrusion 16 to rotate; and a rectangular protrusion cut out on the lens barrel storage end side of the long sliding hole 15. 18, and a fan-shaped hole 15a that allows rotation at an angle of θ and restricts rotation at an angle of θ (see FIGS. 2 and 5).

[Effect of idea]

Since the magnifying glass telescope of this invention has the above-mentioned configuration, the lens barrel 10 incorporating the objective lens 12 is pushed down and rotated below the magnifying glass viewing window 6, so that the magnifying glass viewing window 6 can be opened. Through this, insects on the ground can be easily observed from above. Furthermore, when the telescope is in a switched use state in which the lens barrel 10 is placed horizontally with the gripper 1, the telescope lenses 8 and 12 can be adjusted for distance and distance by sliding the lens barrel 10 in the front and rear directions. Further, in the magnifying glass telescope of the present invention, the gripping body 1 has a concave planar shape, and the lens barrel 10 is stored horizontally in the concave hollow portion 2 of the gripping body, so that it is easy to store and store. It has excellent practical effects such as being convenient and not bulky to carry.
