Abstract

PURPOSE:To Provide a device for simulating a flash light from a gun port of a model gun by a method wherein some flash images illuminated in sequence at a light emitting surface from an operator's side are expanded as an enlarged flash imaginary image by a light collecting means and the enlarged imaginary image is synthesized on a far background scene by an optical synthesizing means such as a half-mirror or the like. CONSTITUTION:When a light emitting surface 11 of a transparent resin plate is coincided with a line connecting a focal point F1 of a convex Fresnel lens 8 with one point P at a circumference, an enlarged imaginary image B at the light emitting surface 11 appears in parallel with an optical axis OQ of the lens 8. A launching trigger 3a of a model laser beam gun % 1 is pushed, thereby the lamps are lit in sequence from a light source 13 by a lighting circuit along with a launching sound. As the imaginary image B of the light emitting surface 11 coming through the lens 8 is synthesized with light passing through a half-mirror 7, the imaginary image B can be seen as a laser beam 6 generated from a gun port 5. In this case, if an image displaying device is applied at an intermediate bottom surface 10, a flash light from the laser beam 6 can be seen to be floated out of a ground when an orientation of the gun is in its horizontal position.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a device in which a light source that blinks in sequence can be seen over a long distance as if emitting a laser beam.

(Prior Art) The present applicant has provided an imaging device in No. 1, Hei 2-107055, in which two line-shaped light sources can be seen continuously over a long distance as if they were emitting laser beams.

L technology involves infinitely reflecting one line-shaped light source between mirrors, superimposing the reflected image on the muzzle of a simulated light gun using a barf mirror, and emitting a laser beam from the muzzle to reach a long distance. It is something that makes it look like it was done.

(Problems to be Solved by the Invention) According to the above invention, it is not possible to sequentially blink the light source from the near side to the far away, and it can only be applied to a laser beam that instantly reaches the target.

This is because the virtual image of the light source is infinitely reflected between the mirrors, so the direction of the virtual image reflected an even number of times is opposite to that of the virtual image reflected an odd number of times. Therefore, the light source is divided into smaller parts and blinked sequentially from the front. The virtual image that was reflected an even number of times flashed from far away to the front, and it was not possible to make the laser beam emitted from the muzzle continuously flash from the front to the far away.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned disadvantages and provides a simulated light gun device in which a laser beam image from the muzzle blinks sequentially from the front so that it appears to reach a far distance.

(Means for solving the problem) By using a condensing means such as a convex lens, a convex Fresnel lens, or a concave mirror, which converges parallel incident light to one point, the condensing means can be used even if a reflecting mirror or the like is interposed. A light source that emits flash light and a display means such as a CRT are provided on a plane that includes the optical axis of the condensing means within the optical focal length of the light source.

A pseudo-simulation system in which the light emitted from the display means is used to obtain an enlarged virtual image using the condensing means and guided to an optical synthesis means such as a half mirror or glass, and the optical synthesis means synthesizes the distant scenery and the enlarged virtual image. Bullet trajectory imaging device.

Using the above-mentioned pseudo bullet trajectory imaging device, the initial position of the enlarged virtual image synthesized with the scenery by the optical synthesis means is the muzzle of the simulated gun, and by operating the firing means such as the firing trigger, the display means flashes. This is a simulated gun that sequentially emits light from one side.

(Function) According to the above configuration, the flash image sequentially blinked from the front side on the light emitting surface is enlarged by the condensing means as an enlarged flash virtual image, and the enlarged virtual image is used as a distant image by an optical synthesis means such as a half mirror. An enlarged flash virtual image is composited onto the scenery to make it appear as if a flash is coming from the muzzle of a simulated gun.

(Example) The present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an external view of the pseudo laser beam gun of the present invention,
The pseudo laser beam gun 1 is attached to the grip 3 of the operating frame 2 on the front side.
Hold the gun, move it freely forward and backward and left and right using the support part 4 at the bottom, aim at the target, press the firing trigger 33, and release the muzzle 5.
At the same time as the laser beam 6, a sound can be emitted from a speaker (not shown).

A shooter aims a gun muzzle 5 through a half mirror 7 that serves as a windshield and a sight, and presses a firing trigger 33 to fire a laser beam 6.

At the bottom of the pseudo laser beam gun 1, there is a support section 4 for the light gun, and in the support section 4, the pseudo laser beam gun 1 is pivotally supported on a horizontal shaft 4a on the upper side of the support section 4, so that the pseudo laser beam gun 1 can be swung back and forth and left and right. , has a structure in which it is rotatably supported by a vertical shaft 4b on the lower side, and although not shown, the horizontal shaft 4a and the vertical shaft 4b are configured to rotate the rotation shaft of the volume via gears. The angle of deflection of the pseudo laser beam gun can be detected electrically.

The structure of the pseudo laser beam gun 1 is such that a half mirror 7 resembling a windshield is attached diagonally downward to the front side of the muzzle 5.
A square convex Fresnel lens 8 is located below the half mirror 7.
is mounted horizontally, and a reflecting mirror 9 is mounted on the lower side thereof, almost parallel to the half mirror 7, with the mirror surface facing diagonally upward and forward, and the edge of the reflecting mirror 9 is in contact with the inner bottom surface 10 of the pseudo laser beam gun 1. ing.

The half mirror 7 described here is made by vacuum-depositing chromium on a glass surface or an acrylic plate, and has the effect of reflecting incident light on a mirror surface and transmitting it as is, and has a low reflectance. If this is the case, a very simple piece of transparent glass or transparent acrylic board will suffice.

Further, the convex Fresnel lens 8 may be a convex lens, and it is obvious that the same effect can be obtained by using the reflecting mirror 9 as a concave mirror without using the convex Fresnel lens 8 or a convex lens.

The middle bottom surface 10 directly below the front of the muzzle 5 is a transmissive resin-based light emitting device that tapers into an elongated isosceles triangular trapezoid shape with the base at the front along the extension line of the laser beam 6 emitted from the muzzle 5. A surface 11 is provided.

FIG. 2 is a perspective view showing the optical system of the pseudo laser beam gun 1 shown in FIG. .

The light emitting surface 11 is orange or red, and the light emitting surface 11
The lower side is subdivided into wall groups 12 parallel to the reflecting mirror 9, and the wall groups 12 become denser as they move away from the reflecting mirror 9, and each space separated by the wall groups 12 has a light emitting surface 11. Light sources such as LED lamps and fluorescent lamps 13
is provided. This light source 13 uses a plurality of light sources 13 near the half mirror 9, where the irradiation area is large, in order to equalize the illuminance of the light emitting surface on the wall group 12 surrounding the corresponding light source 13.

FIG. 3 is a side view showing the relationship between the real image and the virtual image of the light emitting surface in the pseudo laser beam gun. When viewed from the viewpoint 14 of an observer on the near side of the half mirror 7, the image of the light emitting surface 11 of the middle base surface 10 is shown in FIG. is reflected by the reflection mirror 9, passed through the convex Fresnel lens 8, and reflected by the half mirror 7, and the virtual image appears enlarged in front of the half mirror.

Figure 4 is a simplified principle diagram of the optical system of the pseudo laser beam gun.
For the sake of simplicity, the half mirror 7 and the reflecting mirror 9 are omitted because their purpose is to change the direction of light rays, and the convex Fresnel lens 8, light emitting surface 11. The relationship between the observer's viewpoint 14 and the virtual image B of the slit is shown.

When the light-emitting surface 11 of the transparent resin plate is aligned on the line connecting the focal point F1 of the convex Fresnel lens 8 and a point P on the periphery of the convex Fresnel lens 8, the enlarged virtual image B of the light-emitting surface 】l is the convex It appears parallel to the optical axis OQ of the Fresnel lens 8.

To explain these relationships by drawing, the center O of the lens
L is the extension of the line that connects the line passing through and real image A, and the point where real image A intersects the lens surface parallel to the optical axis OQ is L, and the point where the extension of the line connecting focus F2 and L on the opposite side intersects OA. virtual image B
are tied.

When drawing in this manner, the virtual image B of the wall group 12 is formed parallel to the optical axis OQ and equidistant from the optical axis OQ. Similarly, both widths of the light emitting surface 11 are made tapered so as to converge at the focal point F1, so that the enlarged virtual image B becomes a line with the same width.

The width of the wall group 12 of the light emitting surface 11 is arranged so that the virtual images B of the drawing are spaced at equal distances, and the position A1 on the front side of the light emitting surface 11 is the position 1aB1 on the front side of the virtual image is the muzzle of the pseudo laser beam gun. It should be placed at the tip of number 5.

Then, by pressing the firing trigger 3a of the grip 3 of the pseudo laser beam gun 1, the light source 13 separated by the wall group 12 located in front of the convex Fresnel lens is made to blink sequentially with a firing sound and a sequential lighting circuit (not shown). The light appears to be emitted from the gun muzzle 5. Based on the above principle, the effect shown in FIG. The incoming light passes through a convex Fresnel lens 8 and is viewed by magnifying the light from the light emitting surface 11 via a single reflecting mirror 9. Here, the reflection mirror 9 is provided at an angle such that the light emitting surface 11 is located on a line connecting the focal point of the convex Fresnel lens and the side surface of the lens.

In the half mirror 7, the virtual image B of the light emitting surface 11 passing through the convex Fresnel lens 8 is combined with the light passing through the half mirror 7, and the virtual image B at the front end of the light emitting surface 11 is combined with the virtual image B of the front end of the light emitting surface 11 at the muzzle 5. The position of the shooter's eye is the same as that of the above-mentioned observer III, since the laser beam is visible to be emitted forward from the muzzle from the tip and the arrangement of this mirror group is incorporated into the pseudo laser beam gun 1 shown in Fig. 1. It is the same as item 14,
The shooter can see the enlarged virtual image B of the light emitting surface 11 as the laser beam 6 emitted from the muzzle 5 of the gun.

Furthermore, since the virtual image B of this light is made to have the same width, it appears to become thinner as it goes further, giving the impression that the light from the muzzle 5 is being emitted farther away.

In the above explanation, the virtual image B of the light emitting surface 11 was assumed to be linear, but
A zigzag arrangement may also be used, in which case the laser beam will be emitted in a zigzag pattern.

Furthermore, if the light emitting surface 11 is used as an image display surface of a liquid crystal monitor, CRT, etc., the shape of the laser beam 6 can be changed arbitrarily; for example, if it shines in a lightning line shape, it is possible to make a lightning bolt-shaped laser beam. Yes, and if the trajectory of the bullet is projected, it can be seen as if the bullet is flying, widening the range of applications.

If an image display device is used on the middle bottom surface 10, for example, the direction of the gun can be detected on the side of the camera when the laser beam 6 is emitted, so only when the laser beam is in a horizontal position, the ground with a --like pattern can be detected by the laser beam. If displayed together with laser beam 6, it is possible to make the ground appear to be highlighted by the flash of laser beam 6.

Similarly, it is also possible to arrange a light source or an image display device on the side or top surface of the reflecting mirror 9 to produce an image effect by displaying images of countless stars.

Therefore, as shown in FIG. 5, a target 17 is projected on a screen 15 placed in front of the screen 15 using a projection projector 16, and the gunner aims the muzzle 5 of the pseudo laser beam gun 1 at the target 17 and fires the firing trigger 3a of the grip 3. Press 1 to open a circuit to a light source sequential lighting circuit (not shown), which is a known technology, and power is supplied from the same circuit to the light source 13, and the light source 13 sequentially emits light at the moment the firing trigger 3a is pressed.1 Light emitting surface 1

As a result, the gunner who is viewing the image projected on the screen 15 via the half mirror 7 has one shot trigger 3.
The moment 3 is pressed, the laser beam 6 appears to be emitted from the pseudo laser gun 1 toward the target 17 in the distance.

The position of the image projected on the screen 5 and the direction of the pseudo laser beam gun 1 are grasped by a computer.

The computer controls the movement of the target 17 in the video, and the movement of the target 17 is stored in the memory of the computer, and the direction of the pseudo laser beam gun 1 is determined by the horizontal axis 4a and the vertical axis of the support part 4. The direction of the muzzle 5 and the position of the target 17 are checked in real time in the computer by a volume that detects the movement of the gun 4b, and when the firing trigger 3a is pressed and the laser beam 6 reaches the target, the muzzle 5 is If the direction of the target matches the position of the target 17, some kind of action video 1 such as exploding the image of the target 17.
8 is displayed, an explosion sound is emitted from a speaker 19, and a predetermined score is calculated in a computer and displayed on a score display section 20 such as a CRT on a screen 15 or on the side of the pseudo laser beam gun 1.

As shown in the cross-sectional view of another embodiment of the commercial-use vertical video game machine in FIG. A letter-shaped pseudo laser imaging device 22 is provided inside the cylinder 21 with rotating shafts 23 on both sides of the viewing side on the lower side of the cylinder 21, and a gear is fitted to the rotating shaft 23, and the outer side of the cylinder 21 is By rotating a handle 24 installed horizontally on the side, a gear fitted to the handle shaft is rotated via a gear train (not shown) on a rotation shaft 23, thereby tilting the pseudo laser imaging device 22 back and forth. is possible, and by shaking the handle 24 left and right, the cylinder 2
1 rotates.

In the pseudo laser beam imaging device 22, a half mirror 25 is attached diagonally to the base of the inverted T-shape, and the beam passes through and is reflected by a reflecting mirror 26 disposed inside the vertical TV game machine to view a TV monitor 27. .

Further, a convex Fresnel lens 28 is provided above the half mirror 25, and LED lamp groups 29 are arranged so as to become closer and closer to the focal point of the Fresnel lens from the front side of the convex Fresnel lens. has been done.

When the LED lamp group 29 is sequentially blinked from the convex Fresnel lens 28 side by pressing a firing trigger (not shown), the light is magnified by the convex Fresnel lens and it looks like a laser beam has been emitted. Of course, a small television monitor may be used as the LED lamp group 29.

Further, FIG. 7 shows a side view of a bazouga laser gun toy as another embodiment. A half mirror 31 is installed in the scope 30 on the upper side of the gun barrel with the half mirror 31 facing downward.
A reflecting mirror 32 is provided on the lower side facing forward and upward, a convex lens 33 is provided in front of the reflecting mirror 32, and in front of the convex lens 33, light emitters 34 each of which can blink independently are provided.
