DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shooting game light gun, and in particular, uses a light reflection type as a target, and a light emitting part that emits a light beam, a light receiving part that receives the reflected light beam, and a microcomputer. The present invention relates to a shooting game ray gun that has a built-in control circuit that controls the firing sound and emits the sound of a hit.

2. Description of the Related Art Conventionally, light ray guns have been known that emit various firing sounds or cause a plurality of photoreceptors to emit light in various ways by pulling a trigger (for example, US Pat. No. 4,175,353). Also, by pulling the trigger, a light beam is emitted from the light source, and a light-receiving element for receiving this light beam is provided on the target side or in the own or the other party's light beam gun (Utility Model Application Publication No. 114300/1989,
- Publication No. 47300, Jitsugan No. 17991 (Jikko 56)
(No. 54478 Publication)), a type of light gun that changes the appearance of the target or emits a sound when it hits the target, and a type of light gun that projects light from a control box onto a wall etc. and is connected to the control box with a cable. A target game gun device is known in which a light-receiving element for receiving reflected light is provided, and when the light is incident on the light-receiving element, it is a hit, and a control box emits a sound such as a hit sound.

However, in such a ray gun, each part functions to fire a ray after pulling the trigger, emit a firing sound, emit a hit sound each time it hits a target, and count the number of hits if necessary. cannot be performed in the gun itself, and the firing of a bullet in a real gun, hitting the target, and the corresponding firing sound,
The problem was that it lacked realism because it was impossible to simulate the effects of the hit sound.

In addition, such a ray gun has the disadvantage that the device is large and expensive, and it is not suitable for carrying, and the places where the game can be played are limited.

In particular, with a light gun that uses a light-receiving element that receives reflected light from a target, when noise pulses from a fluorescent lamp or the like that is turned on by a commercial power source enter the light-receiving element, it is impossible to distinguish it from the hitting beam. This was accompanied by serious drawbacks that caused this operation.

This emission was made as a result of intensive research to solve the above-mentioned difficulties, and even if noise pulses from a fluorescent lamp turned on by a commercial power supply or other light emitting sources are input to the light receiving element, the rays will not reach the target. To provide a portable shooting game ray gun at a low price that can identify only the target and operate normally, allowing the user to easily enjoy a game similar to actual shooting anywhere.

Next, the target used in the shooting game ray gun 1 according to the present invention will be described in detail.

The target 47 (FIG. 3) is formed by plastic molding, and has a reflector 50 built into a case 49 pivoted to a base 48, and a diameter adjustment plate 52, which is located in front of the reflector by a lever 51. 52' is adjustable.

4' is the pin 55, 55' (5th
(Fig.) through pivot holes 56, respectively. Further, a pin 55'' is planted in the leg portion 54 of the diameter adjusting plate 52, and this pin is fitted into an arcuate long groove 57 bored in the leg portion 54' of the diameter adjusting plate 52'. Figure 5).

The reflecting mirror 50 is attached to the cover 58 at a position corresponding to the reflection hole 59 in the case 49 . The cover can be fixed to the case 49 by screwing screws 60 into screw holes 62.

This reflecting mirror 50 reflects the light beam emitted from the light emitting unit 40 of the light beam gun 1 from any direction and returns to the light beam gun side from which it was fired, and the light beam is reflected back to the light receiving unit provided on the gun side. 43 constitutes a reflective target. Next, this will be explained in detail.
That is, FIG. 6 shows the principle structure of this reflective target. This reflective target is a three-sided reflective mirror 71a, 7
Consists of 1b and 71c. Each reflector 71
a, 71b, 71c are three axial directions (x, y, z
three planes (x-z plane, x-
y plane, yz plane), a reinforcing frame 72 is used to fix this relationship, and three reflecting mirrors 71
a, 71b, and 71c are attached to each side of the reinforcing frame 72. However, the three reflecting mirrors 71a,
71b, 71c are formed by firmly adhering their joining edges, or from the beginning by attaching three reflecting mirrors 71a, 71b,
If 71c is integrally molded in accordance with the above relationship, the reinforcing frame 72 is unnecessary.

In addition, FIG. 6 shows three reflecting mirrors 71a, 71b, 71c that intersect at right angles to each other at their intersecting angles (x
An example will be shown in which an equilateral triangular pyramid is formed with the apex angle being the intersection point O of the axes, y-axes, and z-axes. In other words, the configuration is such that three reflecting mirrors 71a, 71b, and 71c forming three isosceles right triangles having hypotenuses of equal length from the intersection point O are combined in the above relationship. in this way,
Three reflecting mirrors 71a, 71 intersecting each other at right angles
If b and 71c are made into a triangular pyramid with the apex angle at the intersection (intersection O), reflective targets of various sizes can be easily obtained based on the length of the hypotenuse from the intersection O.

The principle of this reflective target is ``If three mirrors are arranged at right angles to each other like three coordinate planes of rectangular coordinates, and a ray of light is reflected once from each of these planes, the ray of light will be reflected at any angle of incidence. Regardless, it returns to the direction it came from.'' (Hiroshi Kubota, Iwanami Shoten, September 1975)
This is based on the phenomenon (see page 7 of "Optics" published in the 8th edition on the 30th). This can be explained using a diagram as follows.

As shown in Figure 8, the three mirror surfaces,
Assume that in an optical system in which L is aligned with three coordinate planes xy, yz, and zx, the light ray L is first reflected on the xy plane, then on the yz plane, and finally on the zx plane. In this case, considering the projections Lxy, Lyz, and Lzx of the ray L onto each plane xy, yz, and zx, the angle of incidence = angle of reflection according to the law of reflection, so each plane whose direction is changed by 2 degrees as shown in the figure Projection Lxy,
Lyz and Lzx are parallel to and opposite the projection of the incident ray. This indicates that the reflected ray returns to the direction from which the incident ray came.

Therefore, if you shine light on a three-panel mirror like this from a single point in the distance, the light will return to its starting point.

Therefore, as long as the above-mentioned reflective target maintains a configuration that matches the triple mirror, the same effects can be expected regardless of its shape and size. In addition, this reflective target is a mirror that simply reflects the irradiated light beam to the firing position, so it has three axes (x, y, z
Even when used as a group of many ray guns at the same time from different angles, as long as they are within the range of the
They do not interfere with each other and can be used without any problems.

Next, Figures 7a, b, and c show another example of this reflective target, which is configured as a triangular pyramid with three reflective mirrors intersecting each other at right angles as described above with the apex angle at the intersection. One unit of target element 73 is 6 target elements 73 (the number is not limited to this,
(Optional) A single reflective target 74 that collectively forms a series of surfaces is shown. It does not matter whether the surface is flat or curved. As a method of assembling each target element 73..., the bottom portions of each target element 73... are joined together to form a continuous surface of the reflecting mirror. Individually independent target elements 73
It is best to use a reinforcing frame when gathering... In some cases, what amounts to a collection of multiple target elements as described above may be initially molded together.

Note that FIG. 7 shows each target element 73 for convenience of illustration.
Although the reflective target 74 constituted by a collection of the target elements 73 and 74 is shown in a fairly large size, in reality, the length of the hypotenuse of one side of one target element 73 is several millimeters or less, and the diameter of the reflective target 74 is approximately 1 centimeter. It can be made in small batches, and it is common to make it in such a size. Of course, the three reflecting mirrors 71a, 71b, 71c shown in FIG.
It is also possible to make and use a material consisting of a single unit in a suitable size.

As explained above, this reflective target is configured as a simple reflective mirror and has an extremely simple structure, so it can be mass-produced at low cost.
Since it is a reflective mirror, it is suitable as a unit for a repeating gun. Moreover, since the reflector is not affected by light attenuation, it is suitable as a long-distance unit. Furthermore, this reflective target can be used as a group of multiple ray guns at the same time from different angles without causing confusion, providing versatility in use. Furthermore, when this reflective target is used, the light emitting device and the light receiving device can all be installed in the ray gun, which has the advantage that the system can be unified.

A fourth target 47 having such a reflecting mirror 50 is
If assembled as shown in the figure, a completed vertical target product as shown in FIG. 3 will be constructed. When the lever 51 is lifted upward, the diameter adjusting plates 52, 52' are expanded around the pins 55, 55', increasing their diameters, and the diameters of the reflector and target become larger, so to speak. If the lever 51 is pressed downward from that position, the plate 52,
52' is reduced in diameter and the target area of the reflector becomes smaller, so it becomes a so-called "professional" position, requiring a high level of skill in shooting technique.

(0.4 seconds) The shooting game light gun according to the present invention configured as described above is handled and operated as follows.

First, the target 47 is set up at an appropriate location on the base 48, and the case 49 is pivoted on the pins 53, 53' of the base 48, so that the target surface is perpendicular to the ray gun side or at an appropriate angle. Adjust.

Also, move the lever 51 up or down to set it to the "amateur" position with a large target diameter or the "professional" position with a small target diameter (FIG. 3).

When the power switch 9 is turned on, the necessary voltages of 9V and 6V are supplied from the batteries B ₁ and B ₂ (Fig. 9) to the lines l ₁ and l ₂ , and the light emitting diode 20 (Figs. 1b and 9) is turned on. The light is turned on to indicate the start, and at the same time, the control ON instruction section 110 is energized, and at the same time, the firing counter 102 is reset by the firing counter reset section 111.

In this state, when the trigger 7 is pulled, a trigger signal generated by the input control section 100 in conjunction with the trigger is applied to the input determination section 101, and its output is supplied to the timer reset section 113 to reset the timer. 11
At the same time, the control OFF instruction unit 12 is reset.
1, the input control unit 100 is cut off, and the input control unit 100 is
After firing, the trigger is not output to the next stage even if the trigger is pulled again until the operation is completed, and the signal is applied to the counter 102 to count up the number of shots by one, and the light emitting output unit 103 is energized for, for example, 0.3 seconds to generate a light emitting gate signal from terminal 87 (FIG. 9). This gate signal is applied to the base of the transistor _Q1 , and a current of approximately 150 mA flows through the filament of the light emitting section 40, and the light emitted from the light emitting section 40 for 0.3 seconds is converted into a parallel beam by the lens 41 and sent to the gun barrel 3'. Light is emitted from.

At the same time, the output from the firing number counter 102 is inputted via the scanning section 104 and the memory 105 to the firing sound selection section 107 in which the sound is selected by the sound changeover switch 8, and is input to the firing sound creating section 108. Then a firing sound like the one mentioned above is created.
The sound amplifier 38a is output as a sound oscillation signal from the terminal 89.
(Figures 9 and 10) is applied to the base of transistor _Q5 . On the other hand, the gate signal created by the emitted sound creation section is generated from the terminal 88, and this signal is biased to the base of the transistor Q ₃ to turn it on, and the capacitor C ₃ charged via the resistor R ₂ is turned on. discharge. Capacitor _C3 starts charging again via resistor _R2 , transistors _Q4 , _Q5 , and resistor _R3 , and according to this charging characteristic, the sound oscillation signal is amplified by transistors _Q4 , _Q5 , and the sound is generated. The sound is emitted from section 38. Capacitor C ₃ is resistor R ₂ ,
_R3 constitutes a time constant circuit, and depending on the time constant, the sound generating section 38 generates a realistic pseudo sound like a shooting sound. Preferably, this emitted sound is gradually attenuated to a length of about 1 second.

Note that the sound selection switch 8 is switched to the selected sound from the next time the sound is emitted.

The light beam emitted from the gun barrel 3' hits the reflector 50 of the target 47 by collimating the target 47 with the sight 10 and sight 12 of the gun as a received light pulse, as shown in FIG. 12. If the reflected light beam returns to the direction from which it came (Figs. 6 to 8), the light focused by the lens 44 enters the light receiving section 43 and is photoelectrically converted (Fig. 9). figure).

The signal output from the light receiving section 43 is a transistor Q ₆
A class amplification is performed using transistor Q7, and a class B amplification is performed using transistor _Q7 to emphasize and amplify the signal.
C ₇ , an optical signal from a fluorescent lamp or the like lit by a commercial power source is shaped into a pulse by the output circuit 90 and sent to the microcomputer 36 .
is applied to terminal 91 of.

Incidentally, the coupling capacitors C ₄ and C ₅ cut out low frequency parts caused by direct current components and hand shakes when holding a gun in the output signal from the light receiving section.

The pulse signal thus obtained is scanned by the scanning section 104 (FIG. 10) for the aforementioned predetermined time, for example, 0.3 seconds, and at a predetermined period, for example, 1 msec. This data is sequentially stored in memory 105. The data stored in the memory is sequentially read out by the hit determination unit 106. In this case, if only one light reception pulse hits in the above 0.3 seconds, it is considered a "hit" as shown in Figure 12.2.
Since the received light pulse is "1" as shown in FIG. 12, the scanning pulse input to the scanning section 104 has the waveform shown in FIG. It becomes "1" as shown in . Figure 5
As shown in Figure 6, when the received light pulses are affected by noise such as from a fluorescent lamp, the number of received light pulses becomes "3" and is scanned as shown in Figure 6.
The scanning output is "3" as shown in Figure 7.
It becomes a pulse. Furthermore, when there is no received light pulse, the scanning output becomes 0 as shown in FIGS. 8 and 9. In this way, even if light from a fluorescent lamp or the like lit by a zero or commercial power supply is input to the light receiving section 43 and filtered as much as possible by the capacitor _C7 , it is not pulsed by the Schmitt circuit 90. When two or more light-receiving pulses, such as external noise whose waveforms have been shaped, are received, each is identified as a "miss" and a hit signal and a miss signal are output, respectively. The hit signal energizes the hit sound generation section 109 to emit the aforementioned hit sound from the sound generation section 38 via the sound amplifier 38a, and also operates the light emitting diode blinking section 115 to blink the light emitting diode 19. Displays a hit.

In the case of a miss, the signal is applied to a miss number counter 116 as a counting means for counting the number of times whether or not a hit signal has been output.
7 and the game ends with a maximum of 10 shots, for example, the calculation is performed to count down by 1 from 10 for each shot, and it is determined whether the game is finished or not. If it is not finished, open the gate of the control ON hit section 110 and turn on the input control section 100.
and prepare for the next launch.

When the end is complete, the all-hit determination unit 119 determines whether or not all hits are achieved, and if all hits are achieved, the Juan Juare creation unit 120 is energized, and if some misses are made, the number-of-misses display sound creation unit 118 is activated. Then, as described above, the sound generation section 38 emits a fan fare sound and a miss sound indicating sound, respectively, via the sound amplifier 38a.

The output from the fanfare sound creation unit 120 and the loss number display sound creation unit 118 both indicate the end of the game, so the output is controlled OFF.
The signal is supplied to the command section 121 to shut off the input control section 100.

If the trigger 7 is not pulled for 30 seconds with the power switch 9 closed, or if 30 seconds elapse without any subsequent trigger operation after the trigger 7 is pulled, the input judgment unit 101 The timer 112 is started in response to the signal, energizing the warning sound generation section 114, and causing the above-mentioned warning sound to be emitted from the sound generation section 38 via the sound amplifier 38a, thereby preventing forgetting to turn off the power.

When one game is completed by firing 10 shots, in order to restart the game, turn off the power switch 9, clear the microcomputer, and then turn it on again to start the game.

In the example described above, when expressing the number of hits,
Although the number of misses is expressed by sound, the shooting game ray gun according to the present invention is not limited to this embodiment, and the display segment can be used to digitally display not only the number of shots fired but also the number of hits. It's okay.

An example of this digital display will be described below.

A sun-shaped display segment 18 used for this purpose is shown in FIGS. 1-2, 9, and 11.
The display segment 18 normally displays the number of shots fired, and the number of hits switch 8a (Figs. 9 and 11)
By pressing the button shown in the figure, the display is switched to display the number of hits.

This changeover switch 8a is preferably installed near the power switch 9 (FIG. 1), for example.

FIG. 11 shows the internal structure of the control circuit in the computer 36, together with the external optical elements, when performing such digital display.

In this figure, the same elements as in FIG. 10 are denoted by the same reference numerals, and the illustration method is also the same as in FIG. 10.

Therefore, only the parts unique to digital display will be explained.

The sun-shaped display segment 18 is driven by a segment control section 130. The control unit 130 is applied with the output from the shot number counter 102 and the output from the hit number counter 131 interposed between the hit determination unit 106 and the hit sound creation unit 109. The control unit 130 changes the number of hits/shots display judgment unit 1 by pressing the number of hits switch 8a.
Via 32, drive control is performed to switch from displaying the number of shots to the number of hits.

The output of the number-of-hits counter 131 is input to the hit sound creation section 109, the light emitting diode flashing section 115, and the end determination section 117, and is also applied to the number of hits display sound creation section 133. Hit number display sound creation part 1
333 cooperates with the total hit determination section 119 to create display sounds corresponding to the number of hits, and causes the sound generation section 38 to emit the sounds via the sound amplifier 38a.

Next, the handling and operation of the light gun in this embodiment for digitally displaying the number of hits will be as follows.

When power switch 9 is turned on, firing number counter 1
02 is reset by the firing counter reset 111, and "0" is displayed on the display segment 18 via the segment control section 130. When the trigger 7 is pulled, the counter 102 counts up by one and "1" is displayed on the segment 18 via the control section 130. When the light beam emitted from the light emitting section 40 hits the target reflecting mirror 50, the reflected light beam is photoelectrically converted by the light receiving section 43, and a hit signal is generated by the hit determination section 106 as in the previous embodiment. Then, the hit number counter 131 is counted up by one. Then, when the number of hits switch 8a is operated, the control unit 130 drives the segment 18 gating only the number of hits signal to display the number of hits via the number of hits/number of shots display judgment unit 132.

In addition, the output of the hit number counter 131 is applied to the hit number sound creation unit 133 together with the total hit output of the total hit determination unit 119, and the hit number display sound as the ending sound is output to the sound amplifier, similar to the end of the game sound in the Juanjuare sound. The sound is emitted from the sound generating section 38 via the sound generating section 38a.

Note that the number-of-hits display sound may be configured to be the same as the number-of-misses display sound described above.

In this way, if the maximum limit is 10 shots per game, segment 18 will contain "1" to "1" for each shot.
“9” and “〓” are displayed for the 10th shot,
Moreover, when all the hits are made, a Juan Huare sound is emitted, and when some misses, the sound corresponding to the number of hits is emitted.

As is clear from the above embodiments, according to the shooting game light gun of the present invention, when the trigger is pulled, a light beam is emitted from the light emitting part, and a shooting sound is emitted.
The gun body incorporates various functions that detect the reflected light that hits the target and returns in the light receiving section, emit a hit sound each time, display the number of hits or misses, or emit a sound as a display sound. You can enjoy a game that is based on actual shooting, and can simulate the effects of firing a bullet in a real gun, hitting a target, the corresponding firing sound, and the generation of the hit sound.

In addition, a control circuit that scans the output signal from the light receiver for a predetermined period at a predetermined period, stores the data, and reads it out to identify only hit signals. Since the external noise input to the light receiving section can be distinguished from the hit signal, it exhibits excellent performance with no malfunctions.

Moreover, the light gun according to the present invention includes the above-mentioned light emitting section,
Since a microcomputer can be built into the gun body as a control circuit for the light receiving section, the creation of various sounds, the sound emission, the display of the number of shots fired, the number of hits, and the sound, the device can be made smaller, inexpensive to manufacture, and portable. The game has many advantages in that it is convenient for people to play the game, and they can play the game anywhere, further improving their hobby.
