[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-emitting material which emits fluorescence by light inside a transparent block in order to make it easy to visually recognize a target appearing in the field of view of a sighting telescope, especially when the field of view is dark. A transparent reticle on which a reticle image is formed, and a light emitting unit for illuminating the transparent reticle,
In addition, a lighting device having an illuminance adjustment mechanism and a switching mechanism illuminates the transparent reticle with illumination light of an appropriate illuminance and color according to the brightness and color of the background, such as at dusk, so that the target can be compared with the background. The present invention relates to providing a transparent reticle with an illuminating device for a sighting telescope that can be easily identified.

[0002]

2. Description of the Related Art As a reticle for facilitating visual recognition of a target at dusk or in a dark field of view, a device for directly or indirectly illuminating a metal reticle has been proposed. . Another example is a glass reticle coated with a fluorescent dye using only one transparent glass plate.
No. 518.

[0003]

In a configuration in which a conventional metal reticle is illuminated directly or indirectly, the reticle appears in the field of view as a dark dark shadow. Therefore, there is a problem that it is difficult to quickly discriminate the target and the background from the reticle while watching the field of view of the sighting telescope in a twilight or a dark background. A reticle image using only one transparent glass plate has a problem in long-term stability of the reticle image.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a transparent reticle having a reticle image formed of a luminescent material that emits fluorescent light by light inside a transparent block, a light emitting section for illuminating the reticle, and an illuminance adjusting mechanism therefor. And an illumination device comprising a switching mechanism, and thereby, from the peripheral surface of the transparent reticle toward the center, illuminance is variable and the illumination light of a small luminous flux capable of switching the color of the illumination light according to the color of the background is applied. ,
By providing at least two types of colors of the illumination light, by providing a transparent reticle with an illuminating device of a sighting telescope, the illumination light of the same color is configured as a pair and illuminates from a position opposite to the center of the transparent reticle. Tried to solve the above problems.

[0005] A transparent reticle having a reticle image formed of a luminescent material which emits fluorescence by light inside a transparent block, a light emitting section for illuminating the transparent reticle, an illuminance adjusting mechanism and a switching mechanism are constituted. A reticle pattern is provided on one surface of one of the pair of transparent plates, a reticle image is formed on the reticle pattern with the light emitting material and the transparent binder, and then one surface of the other transparent plate is laminated and integrated on the one surface. A transparent reticle composed of two plate-shaped transparent blocks was configured.
The light emitting unit is configured on the peripheral surface of the transparent reticle such that illumination light of the light emitting unit is directed toward the center of the transparent reticle. The light-emitting portion has at least two kinds of colors of the illumination light, and the light-emitting portions of the illumination light of the same color form a pair on the peripheral surface of the transparent reticle. Configured in position.

[0006]

The transparent reticle of the present invention has a structure in which a reticle image made of a light-emitting material that emits fluorescence by light is provided inside a transparent block to protect a fluorescent portion of the reticle. Maintain a fine reticle image stably for a long period of time. The light emitting unit of the lighting device is formed on the peripheral surface of the transparent reticle, and the light emitting unit uniformly illuminates the peripheral surface, so that the reticle image can be clearly recognized even at dusk. In addition, with respect to changes in natural conditions such as dusk where the brightness of the background etc. changes every moment, by operating the illuminance adjustment mechanism of the lighting device, a transparent reticle with a brightness that can be easily distinguished from the target and the background. The illuminance with the reticle image can be adjusted, and the color of the illumination light can be switched according to the color tone of the background. Moreover, from the bright and transparent color light, the entire image of the target can be captured in the field of view of the aiming telescope. Discrimination between the background, the target, and the reticle image involves the problem of color perception in addition to illuminance. In general, it can be said that red is a color that can be easily identified with respect to a green background such as a dark background or a forest, and that green is suitable for a background such as a desert. However, the sense of discriminating the colors differs depending on the race, and even if they are of the same race, there are individual differences. Therefore, the color is not limited to the two colors. Accordingly, the present invention provides at least two types of illumination light colors of the light emitting unit, and a pair of illumination lights of the same color in order to perform an appropriate discriminating action in response to differences between races and individuals. Illumination is performed from a position opposing the center of the transparent reticle.

FIG. 1 shows a transparent reticle of the present invention in which a reticle figure is provided on one side of a pair of circular transparent glass plates.
A reticle image is formed by using a fluorescent dye as a material that emits fluorescence by light on the reticle figure and using sodium silicate as a transparent binder, and then laminating and integrating one surface of the other transparent plate on one surface. FIG. 3 is an exploded perspective view of the transparent reticle of the embodiment in which one circular plate-shaped transparent block is formed. On one surface of the circular transparent glass plate 1A of the transparent reticle 1, two etching grooves 2 are provided in a cross shape so as to be orthogonal to the center 1C of the circular transparent glass plate 1A, and the etching groove 2 is located near the center 1C. A reticle pattern 4 is formed as a thin and shallow etching groove 3 which is orthogonal. The reticle image 4A is obtained by applying a fluorescent dye 4C and sodium silicate to the reticle pattern 4. The transparent reticle 1 is formed of a single circular plate-shaped transparent block in which one surface of a transparent glass plate 1B is laminated and integrated on one surface of a circular transparent glass plate 1A on which a reticle image 4A is formed. 5 is a peripheral surface of the transparent reticle 1. Also, a transparent reticle can be easily formed by using, for example, a balsam used for bonding a lens to the transparent binder.

FIG. 2 is a front view showing a main part of an embodiment in which a pair of a red illumination light emitting portion and a green illumination light emitting portion are attached to the peripheral surface of a glass reticle. The light emitting portion of the embodiment has a pair of red diode light emitting members 6R.
And a pair of green diode luminous bodies 6G. The pair of red diode luminous bodies 6R are located on the peripheral surface 5 of the transparent reticle 1 at point-symmetric positions with the center 1C as a symmetric point.
At the center of the peripheral surface equally divided into four by the reticle image 4A, it is attached with the illumination direction toward the center 1C. The pair of green diode luminous bodies 6G is positioned at the center 1 of the transparent reticle 1 from the position of the pair of red diode luminous bodies 6R.
It was attached to a position rotated 90 degrees around C as the center point.

FIG. 3 is a diagram showing a circuit configuration of an embodiment in which an illuminance adjusting mechanism by a voltage dividing mechanism and a switching mechanism of a color of illumination light are integrated by a rotary switch mechanism. The rotary switch mechanism 7 is rotatably supported on the right and left sides in the figure by a power source 7B and an axis point 7C which is also used for adjusting the illuminance and switching the color of the illuminating light as shown by arrows in the figure.
The switch 7P, ten connection terminals 7T including one off terminal 7S arranged in a circle around the axis point 7C and connected to the switch 7P, and one end connected to the connection terminal 7T in FIG. The other ends of the resistors 7a to 7e respectively have a red diode light emitter 6R and a green diode light emitter 6R.
Connected to G. The earth E is common to the power supply 7B, the red diode illuminator 6R and the green diode illuminator 6G.

FIG. 4 is a side sectional view of a sighting telescope in which a transparent reticle with an illumination device according to the present invention is mounted at a focal point of an objective lens of the sighting telescope. Lens barrel 11A of aiming telescope 11
The focal point of the objective lens 8 is located substantially at the center of the transparent reticle 1, and a pair of green diode light emitters 6G and red diode light emitters 6R are mounted on the peripheral surface 5 of the transparent reticle 1 at those positions. The incident light from the objective lens 8 forms an inverted image on the transparent reticle 1, passes through the erect zoom lens 9, and is enlarged by the eyepiece 10. FIG. 5 is a side sectional view of the aiming telescope in which the transparent reticle with the illumination device of the present invention is mounted at the focal point of the erecting zoom lens of the aiming telescope. This embodiment differs from the embodiment shown in FIG. 4 in that the mounting position of the transparent reticle 1 is changed from the focal point of the objective lens 8 to the focal point of the erecting zoom lens 9. There is no change in the imaging of the incident light. In each of the above two examples, a pair of red diodes
The illumination of the light emitting body 6R and the pair of green diode light emitting bodies 6G is performed by the rotary switch mechanism 7 described above.

By operating the rotary switch 7P of the rotary switch mechanism 7, the visual field of the eyepiece 10 is
When the rotary switch 7P is in contact with one of the right connection terminals 7T in FIG. 3, it is illuminated to a suitable illuminance by red when it is in contact with one of the left connection terminals 7T, and by green when it is in contact with one of the left connection terminals 7T.
The background and the target can be easily identified through the transparent reticle 1 having a transparent red or green color tone. Aiming can be performed quickly with a transparent reticle image 4A whose brightness has been sharply increased by a fluorescent dye. The selection of the color and illuminance of the illumination light of the light emitting section
It depends on the color and brightness of the background. In many cases, a combination of two colors, red and green, is effective in discriminating a background, a target, and a reticle image. However, the illumination light is not limited to the above-described combination of two colors because there is a difference in sense of color discrimination due to differences between races and individuals.

The transparent block constituting the transparent reticle of the present invention is not limited to a transparent glass plate. For example, a reticle pattern is provided on one side of a pair of disk-shaped transparent methyl methacrylate resins, a fluorescent dye is used for a material that emits fluorescence by light on the reticle pattern, and methyl methacrylate is used for the transparent binder. It is easy to form one reticle image by forming a reticle image by using a late monomer, and then laminating and integrating one surface of the other transparent plate on one surface. Further, it can be easily carried out by an injection-type internal polymerization method in which a reticle image previously formed of a fluorescent material and a transparent binder is embedded in methyl methacrylate resin by monomer casting with methyl methacrylate monomer. Further, a transparent reticle can be easily formed from a resin material other than the methyl methacrylate resin.

The light-emitting part is not limited to the diode light-emitting body of this embodiment. For example, a light-emitting part in which a color filter is attached to a light-emitting body of a continuous spectrum such as a tungsten lamp or a halogen lamp may be used. A luminous body by discharge light emission having a specific bright line spectrum may be used for the light emitting section.

[0014]

According to the present invention, a transparent reticle having a reticle image made of a fluorescent material or the like is formed at least in order to facilitate identification of a background or a target appearing in the field of view of the aiming telescope, particularly when the field of view is dark. The aim of the present invention is to provide a transparent reticle with a sighting telescope illuminating device that can appropriately illuminate with a two-color illuminating light and an illuminating device having an illuminance adjusting mechanism and a switching mechanism. This has the effect of improving the hit rate on the target.
