2. Description of the Related Art As a reticle for facilitating visual recognition of aiming at a target when it is twilight or when the field of view is dark, a device has already been proposed which illuminates a metal reticle directly or indirectly. .

[0003]

In a conventional structure in which a metal reticle is directly or indirectly illuminated, the reticle appears as a dark black shadow in the visual field. Therefore, there is a problem that it is difficult to quickly distinguish the target or the background from the reticle while gazing at the field of view of the sighting telescope in the dusk or when the background is dark. A reticle image formed by only one transparent glass plate has a problem in long-term stability of the reticle image.

SUMMARY OF THE INVENTION Therefore, according to the present invention, there is provided a transparent reticle having a reticle image formed of a light emitting material which emits fluorescence by light inside a transparent block, a light emitting portion for illuminating the transparent reticle and an illuminance adjusting mechanism thereof. And a switching mechanism, and thereby, from the peripheral surface of the transparent reticle toward the center, illuminating light of a small luminous flux capable of switching the color of the illumination light with variable illuminance and background color, ,
By providing at least two types of colors of the illumination light, by providing a transparent reticle with an illumination device of the aiming telescope configured to illuminate from a pair of opposing positions with the same color of illumination light sandwiching the center of the transparent reticle, I tried to solve the above problems.

A transparent reticle formed with a reticle image made of a light emitting material that emits fluorescence by light inside a transparent block, a light emitting part for illuminating the transparent reticle, an illuminance adjusting mechanism and a switching mechanism thereof are constituted. A reticle figure is provided on one side of a pair of transparent plates, a reticle image is formed on the reticle figure by the light emitting material and a transparent binder, and then one side of the other transparent plate is laminated and integrated on one side. A transparent reticle composed of two plate-shaped transparent blocks was constructed.
The light emitting unit is arranged on the peripheral surface of the transparent reticle so that the illumination light of the light emitting unit is directed toward the center of the transparent reticle. The light emitting portion is composed of at least two types of illumination light colors, and a pair of light emitting portions for illumination light of the same color respectively form a pair on the peripheral surface of the transparent reticle and are point-symmetric with respect to the center point. Configured in position.

[0006]

The transparent reticle of the present invention has a structure in which the fluorescent portion of the reticle is protected by providing a reticle image made of a light-emitting material that emits fluorescence with light inside the transparent block, so that the transparent color tone is improved. Maintains the precise reticle image it has for a long period of time. Since the light emitting portion of the illuminating device is formed on the peripheral surface of the transparent reticle and the light emitting portion illuminates the peripheral surface evenly, the reticle image is clearly visible even in dusk. In addition, with respect to changes in natural conditions such as twilight in which the brightness of the background changes moment by moment, by operating the illuminance adjustment mechanism of the lighting device, the transparent reticle has a brightness that makes it easy to distinguish from the target or 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 colored light, the entire image of the target can be captured in the sight of the sighting telescope. In addition to the illuminance, there is the problem of color perception in order to distinguish between the background, the target and the reticle image. In general, red can be said to be a color that is easy to identify against a dark background or a green background such as a forest, and green can be said to be a suitable color for a background such as a desert. However, the sense of color discrimination differs between races, and even within the same race, there are individual differences. Therefore, it is not limited to the above two colors. Therefore, according to the present invention, in order to perform an appropriate discrimination function in response to a difference between races or an individual difference, at least two types of colors of the illumination light of the light emitting unit are used, and the illumination light of the same color forms a pair. The transparent reticle is illuminated from opposite positions across the center of the reticle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a transparent reticle of the present invention in which a reticle pattern is provided on one surface of a pair of circular transparent glass plates.
A fluorescent dye is used as a material that emits fluorescence by light on the reticle pattern, and a reticle image is formed by using sodium silicate as a transparent binder, and then one surface of the other transparent plate is laminated and integrated on the one surface. It is a separation perspective view of a transparent reticle of an example which was one circular plate-shaped transparent block. 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 each other at a center 1C of the circular transparent glass plate 1A, and the etching groove 2 is formed in the vicinity of the center 1C. A reticle pattern 4 is formed as a thin and shallow etching groove 3 which is orthogonal to each other. The reticle image 4A is the reticle figure 4 coated with the fluorescent dye 4C and sodium silicate. The transparent reticle 1 is composed of one circular plate-shaped transparent block in which one surface of the transparent glass plate 1B is laminated and integrated on one surface of the circular transparent glass plate 1A on which the reticle image 4A is formed. Reference numeral 5 in the drawing denotes a peripheral surface of the transparent reticle 1. Further, the transparent reticle can be easily constructed by using, for example, a balsam used for bonding lenses as the transparent binder.

FIG. 2 is a front view showing a main part of an embodiment in which a pair of a red light emitting light emitting portion and a green light emitting light emitting portion are attached to the peripheral surface of a glass reticle. The light emitting portion of the embodiment includes a pair of red diode light emitters 6R.
And a pair of green diode light emitters 6G. The pair of red diode light-emitting bodies 6R are located on the peripheral surface 5 of the transparent reticle 1 at point-symmetrical positions with the center 1C as the point of symmetry.
In addition, the reticle image 4A is attached to the center of the peripheral surface which is evenly divided into four parts with the illumination direction toward the center 1C. The pair of green diode illuminators 6G is located at the center 1 of the transparent reticle 1 from the position of the pair of red diode illuminants 6R.
It was attached to a position rotated by 90 degrees about C as a 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 an illumination light color switching mechanism are integrated by a rotary switch mechanism. The rotary switch mechanism 7 includes a power source 7B, and a rotary point rotatably supported in the left and right directions in the figure by an axis point 7C for both illumination adjustment and color change of illumination light, which are indicated by arrows in the figure.
A switch 7P, ten connection terminals 7T connected to the switch 7P, including one OFF terminal 7S arranged circumferentially around the axial point 7C, and one end connected to the connection terminal 7T. 7H to 7H and a resistor for voltage drop whose resistance values are different stepwise, and the other ends of the resistors 7A to 7H are the red diode light emitter 6R and the green diode light emitter 6 respectively.
It is connected to G. The ground E is common to the power source 7B, the red diode light emitter 6R, and the green diode light emitter 6G.

FIG. 4 is a side sectional view of an aiming telescope in which the transparent reticle with an illuminating device of the present invention is attached to the focus of the objective lens of the aiming telescope. The lens barrel 11A of the sighting telescope 11
The objective lens 8 has a focal point substantially at the center thereof, and a pair of the green diode light-emitting body 6G and the red diode light-emitting body 6R are formed on the peripheral surface 5 of the transparent reticle 1 and mounted at that position. The incident light from the objective lens 8 forms an inverted image by the transparent reticle 1, passes through the erecting system zoom lens 9, and is enlarged by the eyepiece lens 10. FIG. 5 is a side sectional view of an aiming telescope in which the transparent reticle with an illumination device of the present invention is attached to the focus of the erecting system zoom lens of the aiming telescope. This structure is different from the embodiment shown in FIG. 4 in that the mounting position of the transparent reticle 1 is changed from the focus of the objective lens 8 to the focus of the erecting system zoom lens 9. There is no change in the image formation of the incident light. In both of the above two examples, a pair of red diodes of the light emitting part
Illumination of the red light emitter 6R and the pair of green diode light emitters 6G is performed by the rotary switch mechanism 7 described above.

By operating the rotary switch 7P of the rotary switch mechanism 7, the field of view of the eyepiece lens 10 is
When the rotary switch 7P is in contact with one of the connection terminals 7T on the right side in FIG. 3, it is illuminated in red, and when in contact with one of the connection terminals 7T on the left side, it is illuminated in green with an appropriate illuminance,
The transparent reticle 1 having a transparent red or green color tone can be used as a watermark to easily identify the background or the target. Aiming can be quickly performed by the transparent reticle image 4A whose brightness is clearly increased by the fluorescent dye. To select the color and illuminance of the illumination light of the light emitting part,
This is done according to the color and brightness of the background. The combination of two colors, red and green, is often effective in identifying the background, target, and reticle image. However, the illumination light is not limited to the combination of the above two colors because there is a difference in color identification feeling due to a difference between races and an individual difference.

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

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