Abstract

PURPOSE:To simplify an adjusting work, by making many light emitting parts selectively emit light by operating an input device, and displacing and adjusting a display position of an impact forecasting area which is visually confirmed through a peep-window. CONSTITUTION:Through an input device 24 and a controller 25 fitted to a box 28 of the upper part of a cylindrical body 20, one in the two-dimensional array of a light emission diode 22 provided in the inside of the cylindrical body 20 is selected and made to emit light, its light forms an image on a polarized filter 12b in the rear of a peep-window 10b through a reflector 23, a collector lens 23 and a half-mirror 14, and the image of the light emission diode 22 showing an impact forecasting area can be visually confirmed. When using a rifle, a display position of the impact forecasting area is adjusted by operating a push-button of the input device 24, considering a habit of a bullet, a distance to a target, the direction and strength of the wind, etc. In this way, the adjusting work is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in target scopes, such as rifle scopes, which are often used in rifle scopes.

Generally, a rifle scope is designed so that the shooter can see an image of the target and an image indicating the predicted impact point through the viewing window. this.

The predicted impact point is displayed as follows. for example,
A cross line is drawn and a transparent plate (ractical plate) is interposed in the optical system through which the reflected light from the target passes, and the predicted impact point is indicated at the intersection of the cross.

As another means, a first
One light emitting section is placed in a second optical system that is different from the optical system, and both optical systems are combined in the middle.

The image of this light emitting part displays the predicted impact point.

By the way, assuming that the bullet travels straight, the predicted impact point should be displayed at the center of the viewing window. However, in reality, bullets do not travel straight due to the influence of gravity on guns or bullets (the influence is greater in #1, which has a long distance to the target), the direction and strength of the wind, etc. Therefore, depending on the above conditions, It is necessary to adjust the display position of the expected impact point with respect to the target image.

Traditionally, this adjustment was accomplished by mechanically displacing internal mechanisms. The details will be explained with reference to the conventional device shown in FIG. In FIG. 1, a first cylindrical body 10 constitutes a first optical system 11 through which reflected light from a target passes.

The second cylindrical body 20 constitutes a second optical system 21 through which light from the light emitting section 60 passes. Both optical systems 11.21 are combined by a half mirror 14. That is, the reflected light from the target passes through the half mirror 14 and enters the viewing window 10b.
On the other hand, the light from the light emitting section 60 is reflected by the reflector 23 and reaches the half mirror 14, where it is reflected again and reaches the peephole section 10b.

In this manner, the first curtain of the target and the source of the light emitting section 60 indicating the predicted impact point can be visually recognized through the viewing window section 10b. Next, a mechanism for adjusting the displacement of the light emitting section 60 will be explained. The light emitting section 60 is inserted and fixed at the right end of the inner @61. The left end of this inner cylinder 61 is a ring 62. It is supported by a rubber 63, and the right end is a leaf spring 64.
and a control valve knob 65. Note that another set of leaf springs and 14-node screws (not shown) are installed at positions displaced by 90 degrees with respect to the illustrated leaf springs 64 and V4-node screws 65, and the right end of the inner cylinder 61 is I am starting to support it. By moving the adjusting screw 65 back and forth, the light emitting section 6 provided at the right end of the inner cylinder 61 can be adjusted.
0 in the vertical direction, and turn the other adjusting screw (not shown) to V.
By displacing the light emitting section 60 in the left-right direction (that is, the direction of direct light into the page), the display position of the expected bullet impact point visually recognized in the peephole section 10b can be two-dimensionally adjusted. It is now possible to do so.

However, the conventional device described above has the following drawbacks.

■ When adjusting the display position of the predicted impact point two-dimensionally,
The two adjustment screws must be operated separately, making the adjustment work complicated.

■ The work itself of turning the adjustment screw and setting it at a predetermined position is troublesome.

The present invention was developed based on the above circumstances, and an object of the present invention is to provide a target scope that can greatly simplify the work of adjusting the display position of the predicted impact point.

In order to achieve the above object, the target scope of the present invention includes a plurality of light emitting parts arranged in a second optical system, an input device and a control device, and a control device according to data input from the input device. This allows the large number of light emitting sections to selectively emit light.

An embodiment in which the present invention is applied to a rifle scope will be described below with reference to FIGS. 2 to 6.

In FIG. 2, reference numeral 10 indicates the first cylindrical body 4. As shown in FIG. Plastic polarizing filters 12m and 12b are provided at both ends of the cylinder 100, that is, the entrance portion 101 and the viewing window portion 10b, and window glass plates 13m and 13b are provided inside thereof. Furthermore, this
Inside the cylinder 10, there is a 71-7 mirror 14 located between the window glass plates 13m and 13b at a position close to the viewing window 10b.
is located. This 1-7 mirror 14 is the inner cylinder 15
It is fixed at an angle of 45 degrees. Then, the reflected light from the target is filtered through a polarizing filter 1 at the right end entry section 10a.
2m, passes through the window glass plate 13a, the 1-7 mirror 14° and the window glass plate 13b in order, and reaches the dip polarizing filter 12b in the left end peephole 10b.

This allows the shooter to visually recognize K11l-like A as shown in Figure 4. In this way, the first optical system 11 is configured.

Reference numeral 20 indicates a second cylindrical body. This second cylindrical body 20 is connected to the aforementioned ninth cylindrical body 10 by a screw 31. These barrels 10.20 are fixed to a rifle (not shown) by fixtures 30.30. At the junction of these cylinders 10.20, the ＼-7 mirror 1
An opening is formed directly above 4, and a collector lens 32 is attached to this opening. The right end portion of the second cylindrical body 20 houses a light emitting diode, which will be described later, and a battery that serves as a power source for the control device. Inside the cylindrical body 20, there are light emitting diodes 22 as light emitting parts.
are two-dimensionally arranged in large numbers on a plane perpendicular to the optical axis of the second optical system 21, which will be described later. The light from the light emitting diodes 22 is reflected by a reflecting mirror 23 fixed at a 45° angle to the closed left end of the second cylindrical body 20, and passes through a collector lens 32 to form the aforementioned half mirror. 14, where it is further reflected, and after passing through the window glass plate 13b, it reaches the polarizing filter 12b in the viewing window section 10b at the left end of the first cylinder 10,
This allows the shooter to visually recognize the image of the light emitting section 22 indicating the predicted impact point, as shown in FIG. In this way, the second optical system 21 is configured. As is clear from the above description, the first optical system 11 and the second optical system 21 are combined by the half mirror 14.

A box 28 is attached to the upper part of the second cylindrical body 20. The input device 2 is provided on the top of this box 28.
4, and a control device 25 is housed inside. As shown in the block diagram of FIG. 6, this control device 25 consists of a decoder 26 and a display driving means 27.
The decoder 26 sends a drive signal to the display drive means 27 in accordance with information input from the input device 24, thereby causing the light emitting diode 22 described above to selectively emit light. The input device 24 has a large number of push buttons as shown in FIG. Button rLJ is to the left with respect to the center 0 of the peephole portion 10b shown in FIG. 4, "R" is to the right,
"U" means upward, "D" means downward.
, riJ, [2J, and raJ each represent the distance from the center O of the viewing window 10b, for example,
0" is the center, "1" is 0.1 inch (however, 1 inch is 2.54c ugly), r2j is 02 inches, "3" is 0.3
Represents inches.

When actually using a rifle, the expected bullet impact displayed on the riflescope's viewing window 10b takes into consideration the nature of the gun or bullet, the distance to the target, the direction and strength of the wind. Adjust the position of the point. For example, if it is necessary to display the predicted bullet impact point at a position shifted 0.1 inch to the left and 0.1 inch downward from the center position of the viewing window 10b, press button rLJ of the input device 24,
rlJ.

Press rDJ and rlJ in sequence. The information inputted by this push button operation is decoded by the decoder 26, and based on the signal sent from the decoder 26 to the display driving means 27, one of the many light emitting diodes 22 corresponding to the above-mentioned designated position is selected. The light emitting diodes 22 are energized and emit light. As a result, the image of the light emitting diode 22 can be visually recognized in the peephole 10b at the specified position.

In this way, by operating the buttons on the input device 24, the light emitting diodes 22... can be selectively caused to emit light, thereby adjusting the display position of the predicted impact point.

Note that the present invention is not limited to the first embodiment described above, and various embodiments are possible. For example, by making the diameter of the light emitting diode even smaller and arranging more light emitting diodes,
The display position of the predicted arrival point of the bullet may be adjusted more precisely.

(9) Optical fibers may be integrally extended to each of the plurality of light emitting diodes, and the tips of the optical fibers may be arranged on a plane perpendicular to the optical axis of the second optical system. In this case, the tip of the optical fiber becomes the light emitting part.

Moreover, in this case, the light emitting diode may be arranged in any direction with respect to the optical axis, for example, it may be arranged along the inner circumferential surface of the second cylindrical body.

As shown in FIG. 7, it is also possible to significantly increase the amount of data input by the input device 49.

That is, this input device 40 has a button group 41m corresponding to the type of gun and a button group 41b corresponding to the type of bullet.
Button group 41c corresponding to the distance at the peephole
It has Furthermore, in this case, the control device 42 has a microcomputer 43 and a display driving means 44, as shown in FIG. The microcomputer 43 receives the command from the input device 40, and the display driving means 44
A signal is sent to the light emitting section 45 to selectively cause a large number of light emitting sections 45 to emit light. The input device 40 is operated as follows. That is, each button group has 41 meters of buttons that indicate the type of gun and bullet that will actually be used.

Select from 41b and press. In addition, the direction and strength of the wind,
The button group 41c is operated in consideration of the distance to the target, etc. For example, if you want to shift the display position of the bullet's expected arrival point in the peephole further down by 0.3 inch8 and to the left by 0.02 inch depending on the wind and distance to the target conditions, use rDj, rOj.

・Press the J, r3J buttons, and then rLJ, rO
J.

[・Press the J, rOJ, and r2J buttons. In this way, one light emitting part 45 corresponding to the accurate expected impact point
can be made to emit light. The input device 40 is configured to input information such as the direction and strength of the wind, the distance to the target, etc. by pressing a button, and automatically convert the information using a microcomputer to adjust the display position of the predicted impact point. It's okay.

The light emitting section may be constituted by a large number of anode segment electrodes 51 arranged on the fluorescent display panel 50 as shown in FIG. 9 (FIG. 9 is an enlarged view of a part of the fluorescent display panel 50). . In this fluorescent display panel 50, thermoelectrons emitted from a filament cathode in a flat vacuum container are accelerated by a grid electrode and collided with a phosphor on an anode segment electrode 51 to emit light. The fluorescent display panel 50 is controlled by an input device 40 as shown in FIG. The control device 42 selectively applies a voltage to the plurality of segment electrodes 51 to produce a light emitting effect.

Furthermore, the light emitting part is a plasma display panel? EL
It may be constituted by a large number of segment elements such as panels (electroluminescent panels).

The image of the light emitting part that is visually recognized in the viewing window can be made larger or smaller than the actual light emitting part by interposing a convex lens, a concave lens, or a combination thereof between the light emitting part and the reflecting mirror.

The number of light emitting parts that selectively emit light may not be one but a plurality. For example, a plurality of light emitting parts may emit light to form a cross-shaped air as a whole, and the center thereof may be set as the predicted impact point.

Furthermore, it may be configured as shown in FIG.

In the figure, 70 is a cylindrical body, and an objective lens 71 is installed in a light receiving section 70m of this cylindrical body 70, and an eyepiece lens 72 is installed in a viewing window 70b.

Moreover, a half-mi 5-73 is installed in the middle part of the cylinder body 70. The reflected light from the target is directed from the objective lens 71 to the eyepiece lens 72 via a half mirror 73, a large number of lens groups 74, and so on. This enlarges the archer and allows him to see his naked body. As is clear from the above description, the first optical system 75 is configured along the axis of the cylinder 70. In addition, the cylindrical body 70
Inside, a large number of light emitting diodes 76 (light emitting parts) are installed at positions facing the half mirror 73. The optical path from the light emitting diodes 76 to the half mirror 73 constitutes a second optical system 77. The light emitting diodes 76 are arranged on a plane substantially perpendicular to the optical axis of the second optical system 77. A box 78 is installed outside the cylinder 1, and this box 78
A control device, an input device, a battery, etc. for selectively controlling the light emission of the light emitting diodes 76, etc. are built in. The light from the light emitting diode 76... is bar 7mi 2-7
3 and reaches the eyepiece lens 72, which serves as a trap so that the displayed image of the predicted impact point can be visually recognized. In the figure, reference numeral 79 is a zoom ring, and by rotating this ring, zooming is performed via a zoom mechanism (not shown).

Ninth, a prism may be used instead of a half mirror to combine the first optical system and the second optical system.

Furthermore, it goes without saying that the present invention can be applied to target scopes other than rifle scopes.

As explained above, the present invention selectively causes a large number of light emitting sections to emit light by operating an input device, thereby adjusting the displacement of the display position of the predicted impact point that is visible in the viewing window section. . This has the effect that the display position of the predicted bullet impact point can be adjusted very easily.
