がいろいろなされている。[Detailed Description of the Invention] The main factors related to the accuracy of gunfire are shooting distance, parallax, bullet type, initial velocity of bullet,
In order to improve shooting accuracy due to the movement of the target, it is necessary to correct the direction of the gun barrel, which takes into account the main factors related to hit accuracy. In recent years, with the remarkable progress of small computers and laser distance measuring devices,
The accuracy of firing distance is improved by using a laser rangefinder, and factors related to accuracy such as firing distance, parallax, bullet type, initial velocity of the bullet, target movement, etc. are entered into a computer, and future correction amounts are calculated and the gun barrel is adjusted. Attempts are being made to make direction corrections. The aiming glasses, which are a part of the fire control system, were also developed in this way by installing a movable reticle for aiming the gun inside the glasses, and automatically moving the movable reticle by the amount of future correction calculated by the computer. Various measures have been taken to make it easier to obtain a line of sight for shooting, which corresponds to direction correction.

作が必要となつていた。 In such a case, it is desirable for the aiming operation that the distance measuring aiming point of the laser distance measuring device system is displayed as a distance measuring aiming indicator together with the shooting aiming indicator on the reticle within the field of view of the aiming glasses. However, in general, the distance measurement line of sight of a laser rangefinder system is fixed, so when the shooting sight line of sight changes due to the movement of the movable reticle, the shooting sight index and distance measurement sight line will appear within the field of view of the sight glasses. The indicators will be displayed in different places. For this reason, the aiming operation for shooting required a double operation: first setting the target with the distance measuring sight index, measuring the distance, and then capturing the target with the shooting sight index and firing.

１を同一中心位置に設定することが可能である。 For example, FIG. 1 shows a basic schematic configuration of a conventional device having a laser rangefinder system 20 and a sighting glasses system 10, and the conventional technique will be explained using this diagram. In FIG. 1, the sighting glasses system 10 includes an objective lens 11,
It is composed of an erecting prism 12, an eyepiece 13, a movable reticle 14, and a fixed reticle 15.
The laser distance measuring system 20 includes an inverted Galilean beam expander consisting of an objective lens 21 and an eyepiece 22, a laser transmission system using a laser 23, an objective lens 21, a perforated mirror 24, a total reflection mirror 25, and a pinhole mask 26. , relay lens 2
7. Consists of a laser receiving system using a light receiving sensor 28. Here, the perforated mirror 24 allows the laser beam to pass through a hole provided in the mirror during laser transmission, and has a total reflection effect only on the laser receiving system. Normally, with such an optical device, in principle, the optical axis 16 of the sighting glasses system 10 and the optical axis 29 of the laser rangefinder system 20 only need to coincide with the gun axis when the optical device is attached to the gun. in,
In this case, as shown in FIG.
1 can be set at the same central position.

Therefore, normally a shooting sight indicator 40 as shown in FIG.
The reticle 14 (Fig. 1) engraved with is used as a moving reticle, and this moving reticle is moved based on the calculation results that take into account the factors for increasing the accuracy mentioned above, and the shooting aiming index 40 after the movement is also determined. The direction of the gun barrel is being corrected.

分hyだけ移動することになる。 FIG. 3 is a principle diagram illustrating this process, and shows a sighting glasses system consisting of an objective lens 50, an eyepiece lens 51, and a reticle 52. In the same figure,
Assuming that the initial shooting sight line of sight coincides with the optical axis 53, once the future correction amount θ (corrected shooting sight line of sight 53') of the sight glasses corresponding to the amount of direction correction of the gun barrel is determined, the focus of the objective lens 50 can be determined. Let the distance be f
It is sufficient to move the reticle 52 having the shooting aiming index by f.tanθ=h from point P to point P'. Then, if the aiming glasses system is moved so that the moved shooting aiming index matches the target (and at the same time, the direction of the gun barrel that is integrated with this is corrected), the aiming operation that takes into account the amount of future correction is completed. It turns out. In order to simplify the explanation, here we have shown the correction within one plane, but in general, θ is three-dimensional (including the component in the direction perpendicular to the plane of the paper in Fig. 3), so As shown in FIG. 4, the shooting aiming index moves from point P to point P' by an x-axis component hx and a y-axis component hy.

距離を変えながら移動してゆく目標に対しては命
中精度の低下が避けられない欠点であつた。 After moving the shooting aiming index from point P to point P' as shown in Figure 4, the target is captured and shot at this point P', but with a laser rangefinder system, the rangefinder sight indicator is moved from point P to point P'. Since the line does not change with respect to the optical axis of the sighting glasses system (because it coincides with the gun sight line), the indicator 41 of the distance measurement sight line is set at the 4th point as in Fig. 2.
It is at the same position 41 in the figure. Therefore, in the aiming operation for shooting, first measure the distance using the distance measuring sighting indicator 41 shown in Figure 2 to match the target, and then use the shooting aiming indicator at point P' in Figure 4, which has been moved taking other factors into consideration. Two actions are required: catching the object and shooting. This type of aiming operation is extremely inconvenient if the target is stationary, but if the target is moving and you are attempting to aim while tracking it. In other words, once you have captured the target with the rangefinder system, and then captured the target again with the corrected shooting aiming index, the rangefinder system's line of sight no longer matches the target, and you can continue measuring the distance as is. I can't. Therefore, a drop in accuracy was an unavoidable drawback for targets that moved while changing distance.
本発明は以上の事情に鑑み、射撃の照準動作が

せることが可能となるものである。 In view of the above circumstances, the present invention improves the fact that the aiming action for shooting requires two movements, and by matching the shooting aiming index with the target, the above-mentioned method can be achieved even when the target is moving. This makes it possible to continue aiming while taking future correction amounts into consideration while measuring distance using only aiming operations.

FIG. 5 shows an embodiment of the optical device of the present invention, and as shown in FIG. 5, a laser distance measuring system 60, a sighting glasses system 70, and a reticle projection optical system forming a part of the sighting glasses system are shown in FIG. It is composed of 80. The laser distance measuring device system 60 has an objective lens 61
It consists of an inverted Galilean beam expander consisting of an eyepiece 62, a laser transmission system using a laser 63, an objective lens 61, a perforated mirror 64, a total reflection mirror 65, a pinhole mask 66, a relay lens 67, and a light receiving sensor 68. ing. Here, the perforated mirror 64 has the effect of a total reflection mirror only in the laser receiving system, with the laser light passing through the hole provided in the mirror during laser transmission. On the other hand, the sighting glasses system 70 includes an objective lens 71, an erecting prism 72, an eyepiece lens 73, a projection lens 81, and a total reflection mirror 8 for changing the optical path.
3. It is composed of a reticle projection optical system 80 composed of a reticle 82 and an illumination lamp 84.
A beam of light from the reticle projection optical system 80 is transmitted through a semi-transparent mirror 77 which is tilted obliquely (45 degrees) with respect to the optical axis 75 of the sighting glasses system at the tip of the objective lens 71.
The light is reflected by one reflecting surface 79 and enters the objective lens 71, forming an optical image reticle of a reticle 82 on the focal plane of the objective lens 71. Here, when the inclination angle of the semi-transparent mirror 77 with respect to the optical axis 75 of the aiming glasses system 70 is changed, the optical image reticle 74 moves in the focal plane of the objective lens 71, and becomes a moving reticle for aiming. On the other hand, the light beam 69 from the laser rangefinder system is totally reflected by the total reflection mirror 76 for changing the optical path, and further reflected by the back surface 78 of the surface 79 of the semi-transparent mirror 77 that reflects the light beam from the reticle projection optical system 80. It is reflected in the direction of 85.

子を第６図で詳しく説明する。 When the optical device according to the present invention is configured in this way,
By changing the inclination angle of the semi-transparent mirror 77 with respect to the optical axis 75 of the sighting glasses system, the distance measurement line of sight of the laser rangefinder moves in conjunction with the shooting sight line of the sighting glasses system, facilitating the aiming operation. However, this situation will be explained in detail with reference to FIG.

線８５と合致する。 In Fig. 6, the optical axis of the laser distance meter system is represented by the ray 69, and if the distance measurement line of sight of the laser distance meter system is the same as the direction in which the optical axis faces, then first When the lens 77 is placed at an angle of 45 degrees with respect to the optical axis 75 of the sighting goggle system, the distance measurement axis 85 is in the same direction as the optical axis 75 of the sighting goggle system. On the other hand, if the reticle center of the reticle projection optical system is on the optical axis of the reticle projection optical system, this image is formed at point P on the optical axis of the sighting glasses system, so the shooting sight line of the sight glasses system is is the same as the optical axis 75 of the aiming glasses system, and coincides with the distance measuring line of sight 85 of the laser distance measuring device system.
次に半透鏡７７がθ／２だけ傾きを変えて７
７′の位置に動いたとすると、レーザー測遠機系
の測遠視軸線８５はθ傾き８５′となる。 Next, the semi-transparent mirror 77 changes its tilt by θ/2 and
If it moves to the position 7', the distance measuring axis 85 of the laser distance measuring device system has an inclination θ of 85'.
一方レチクル投影光学系の光軸は８６で示され

常に合致させることが出来る。 On the other hand, as shown at 86, the optical axis of the reticle projection optical system is inclined by θ from the optical axis 75 of the sighting glasses system, and the image of the center of the reticle is focused by the objective lens 71 at point P'. At this time, the amount of movement from point P to point P' is expressed as '=f' tan θ, where f' is the focal length of the objective lens. Therefore, the sight line of sight for sight glasses is
It is represented by a line 87 connecting the point P′ and the center of the lens 71, and since ′=f′tanθ, the shooting sight line 87
is parallel to the distance measurement line of sight 85' of the laser distance measurement system, so by changing the inclination of the semi-transparent mirror 77, the optical image reticle is moved by the amount of future correction of the aiming glasses corresponding to the amount of direction correction of the gun barrel. At the same time, the distance measuring line of sight of the laser rangefinder system can always be aligned with the shooting sight line of the sighting glasses system.
第６図では説明の煩雑になるのを避けるために
正立プリズム等は省略して基本的構成だけを示し
てあり、また一平面内での説明にとどめてある
が、一般にはθは立体的な量で表されていること
は第４図に示した場合と同様である。 In Figure 6, to avoid complicating the explanation, only the basic configuration is shown, omitting the erecting prism, etc., and the explanation is limited to one plane, but in general, θ is three-dimensional. The fact that it is expressed as a quantity is the same as in the case shown in FIG.

ない。 In addition, recently, YAG lasers are often used as lasers in laser distance measuring systems, but in such cases, one side 78 of the semi-transparent mirror shown in FIG.
As shown in the figure, a dichroic film that reflects the wavelength of the YAG laser and transmits visible light is formed, and a semi-transparent film that acts as a semi-transparent mirror for visible light is formed on the back surface 79, thereby increasing the laser power. can be used effectively. Also, this semi-transparent mirror is 50%
It goes without saying that this does not mean only reflection and 50% transmission, and the ratio of reflection and transmission may be changed as appropriate depending on the brightness of the reticle projection optical system.

のである。 As described in detail above, according to the optical device of the present invention, the distance measuring line of sight of the distance measuring device is linked with the movement of the shooting aiming index by the optical image reticle, which moves according to the amount of future correction, and It is possible to carry out aiming with future correction while constantly measuring the distance in order to change it so that it matches. Therefore, even if you are shooting a moving target or an object whose shooting distance is changing moment by moment during the movement process, you can always improve your accuracy by aligning the distance measurement aiming index with the target and tracking it. It is capable of high-level shooting.

の光学装置。[Scope of Claims] 1. In an optical device having a laser rangefinder system and a sighting glasses system, a semi-transparent mirror is arranged at the tip of the objective lens of the sighting glasses system so as to be inclined with respect to the optical axis of the sighting glasses system, A beam of light from a reticle projection optical system forming a part of the sighting glasses system is made incident on the objective lens of the sighting glasses system through the semi-transparent mirror, and aiming is performed by changing the inclination angle of the semi-transparent mirror with respect to the optical axis of the sight glasses system. A movable reticle for optical aiming is formed within the field of view of the eyeglass system, and the beam from the laser rangefinder system is reflected by using the back surface of the surface of the semi-transparent mirror that reflects the beam from the reticle projection system. By changing the inclination angle of the semi-transparent mirror with respect to the optical axis of the sighting glasses system, the distance measuring line of sight of the laser rangefinder system moves in conjunction with the shooting sight line of sight of the sight glasses system. An optical device featuring: 2. A dichroic film that reflects the wavelength of the YAG laser and transmits visible light is formed on one side of the semi-transparent mirror, and a semi-transparent film that becomes a semi-transparent mirror for visible light is formed on the back side of the semi-transparent mirror. The optical device according to scope 1.
