[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ray gun game machine which shoots at a monitor screen.

[0002]

2. Description of the Related Art In recent years, a ray gun game machine has been proposed which shoots a game screen on a multi-screen consisting of a plurality of monitors with a ray gun (Japanese Patent Laid-Open No. 62-49881). In this game machine, high-intensity scanning lines are generated at a predetermined fine pitch on the screen to enable detection of the shooting position by the light gun and identification of the monitor screen shot, and scanning thereof. The line phase is generated by shifting it for each screen. Then, the monitor is judged to have been shot by detecting the high-intensity scanning line that coincides with the shooting timing.

[0003]

In the above-mentioned game machine, a switch section for switching the brightness, a counter for opening and closing the switch section at the timing of shifting the phase for each screen, and for operating these switch sections and counters However, the peripheral circuit and the like are required, and the configuration of the control unit is inevitably complicated.

In the above control method, the more monitors are provided, the coarser the pitch of the high-intensity scanning lines must be made. On the other hand, the light gun detects only the high-intensity scanning lines. As the number increases, the vertical resolution of the light receiving unit decreases. Further, there is a problem that the image quality of the game screen is deteriorated due to the enlargement of the pitch of the high-intensity scanning lines.

The present invention has been made in view of the above circumstances, and in a light gun game machine having a plurality of monitors, it is possible to easily monitor a shot screen without lowering scanning line detection resolution. It is an object of the present invention to provide a ray gun game machine that can be easily identified with various configurations.

[0006]

The invention according to claim 1 is
A light gun that emits light from the scanning bright line on the monitor screen, which receives light from the direction in which the muzzle is directed, and a monitor that displays the target and also receives light when the light gun is triggered In a light gun game machine including a game machine main body that detects the shooting position on the monitor screen from the timing and the scanning line position on the screen at that time to determine whether or not the target has been shot, the monitor is the first , A second monitor, and a polarization filter having a deflection surface of a first angle is arranged on the screen of the first monitor.
The screen of the monitor is provided with a polarizing filter having a second deflecting surface different from the first angle, and the light gun has a first light receiving portion and a second light receiving portion in the muzzle, A polarization filter having a deflection surface equal to the first angle is disposed on the front surface of the first light receiving portion, and the second light receiving portion is provided on the front surface of the second light receiving portion.
A polarizing filter having a deflection surface equal to the angle of is arranged, and the game machine main body section determines whether or not the target is shot to the first monitor when the first light receiving section outputs a light receiving signal. When the second light receiving section outputs a light receiving signal, the second monitor is configured to determine whether or not the target has been shot.

According to a second aspect of the present invention, in the light gun game machine according to the first aspect, a third monitor is provided, and in the game machine main body section, the first and second light receiving sections simultaneously receive light receiving signals. When outputting, the third monitor is configured to determine whether or not the target has been shot.

According to a third aspect of the present invention, there is provided a light ray gun for receiving the light emitted from the scanning bright line on the monitor screen from the direction in which the muzzle is directed, and a monitor for displaying the target and a light ray. A light beam consisting of the game machine main unit that detects the shooting position on the monitor screen based on the light receiving timing when the gun is triggered and the scanning line position on the screen at that time and determines whether or not the target has been shot In the gun game machine, the monitor is composed of a first monitor and a second monitor, a polarization filter having a deflection surface of a first angle is arranged on the screen of the first monitor, and the ray gun has a muzzle. A polarization filter having a first light receiving portion and a second light receiving portion therein, and a front surface of the second light receiving portion having a polarization plane of a second angle different from the first angle is disposed. The game console body is
When only the first light receiving unit outputs the light receiving signal, it is determined whether or not the target has been shot against the first monitor.
When the second light receiving unit outputs the light receiving signals at the same time, the second monitor is configured to determine whether or not the target has been shot.

[0009]

According to the first aspect of the present invention, the light beam from the first monitor screen passes through the polarization filter to extract only the polarized light of the first angle, and this polarized light is the polarized light of the first angle. The first light receiving portion provided with the filter receives the light and outputs a light reception signal. On the other hand, the light beam from the second monitor screen passes through the polarization filter and only the polarized light component of the second angle is taken out. This polarized light is received by the second light receiving unit provided with the second angle polarization filter. Light is received and a light reception signal is output.

According to the invention described in claim 2, since the polarization filter is not attached to the third monitor,
Light-receiving signals are simultaneously output from the first light-receiving unit and the second light-receiving unit, and at this time, the game machine main body unit determines whether or not the target is shot by the third monitor.

According to the third aspect of the present invention, the light beam from the first monitor screen passes through the polarization filter and only the polarized light component of the first angle is taken out. As a result, the first light receiving section receives the light beam. Although the light is received and a light receiving signal is output, the light receiving signal is not output because the light is not received by the second light receiving section provided with the polarization filter of the second angle. Further, the light beam from the second monitor screen is received by the first light receiving unit and the second light receiving unit, and a light receiving signal is output at the same time. Therefore, in the game machine main body, when two light receiving signals are simultaneously output,
Whether the target has been shot or not is determined by the second monitor,
When the light receiving signal is output only by the first light receiving unit, the first
The above determination is performed on the monitor.

1 shows a schematic structure of a light gun game machine according to the present invention, which is composed of a main body 1 and a light gun 2 for shooting. The main body 1 is made up of a cathode ray tube or the like and has three monitors C for displaying targets and the like.
RT1 to CRT3, first polarizing filters 11h and 11v mounted on the screens of these monitors CRT1 and CRT3, a control unit 12 for advancing a game, and monitors CRT1 to CRT3
Sweeping circuit 13 for scanning each beam of H.V., H / V counter 14 for monitoring the scanning position of the beam, and determining means 15 for determining which monitor the shot screen belongs to.
And so on.

The first polarizing filters 11h and 11v extract linearly polarized light whose natural vibration plane is on a flat plane from the natural light. The first polarizing filter 11h extracts first linearly polarized light in the horizontal direction. The first polarization filter 11v is mounted on the front surface of the screen of the monitor CRT1 at the take-out angle (first angle), and the first polarization filter 11v takes the second polarized light take-out angle (second angle) at which the linearly polarized light in the vertical direction is taken out. It is mounted on the front.

The sweep circuit 13 sweeps in synchronization with each monitor by the signal from the control unit 12, and monitors CRT1 to CRT3 at each instant.
The scanning positions of the respective beams are the same horizontal and vertical positions.

The H / V counter 14 monitors the beam scanning positions of the monitors CRT1 to CRT3 in response to a signal from the control unit 12, and counts the horizontal and vertical scanning positions of the beams. There is.

The light gun 2 controls a shooting signal when two light receiving portions 21h and 21v for converting an incident light beam into a light receiving signal, second polarizing filters 22h and 22v, and a trigger (not shown) are operated. Shooting signal generating means 23 for outputting to the section 12
It has. The light receiving portions 21h and 21v have a light receiving surface on which light rays are incident, and are provided inside the barrel 20 with the light receiving surface facing the direction of the muzzle 20a. Optical lenses (not shown) having a high directivity are provided on the front surface of the light receiving surface, and the light rays from the scanning bright lines are condensed and guided to the light receiving surface. At this time, the light receiving units 21h and 21v convert the incident light beam into an electric signal and output the light receiving signals Sh and Sv when the level of the electric signal is equal to or higher than a predetermined level.
Sv is output to the determination means 15 described later.

The second polarizing filters 22h and 22v extract linearly polarized light from natural light. When the light gun 2 is set in a normal shooting posture such that a trigger (not shown) is in a substantially vertical direction, The two-polarization filter 22h has a first polarization extraction angle so that the linearly polarized light in the horizontal direction is transmitted therethrough.
It is mounted on the front surface of 1h, and similarly the second polarizing filter 22v
Is attached to the front surface of the light receiving portion 21v at the second polarization extraction angle so that the above-mentioned linearly polarized light in the vertical direction is transmitted.

As shown in Table 1, the judging means 15 is set to the above-mentioned 2
The light gun 2 monitors C based on the two received light signals Sh and Sv.
Identify which screen of RT1 to CRT3 you shot,
The results are immediately output to the control unit 12 as monitor selection signals Stv1 to Stv3.

[0019]

[Table 1]

In Table 1 above, "1" indicates a state with a light receiving signal, and "0" indicates a state without a light receiving signal. When only the light reception signal Sh is input, the determination means 15 determines that the monitor CRT1 has been shot, and determines the monitor selection signal Stv1. When only the light reception signal Sv is input, the determination means 15 determines that the monitor CRT3 has been shot. Then, the monitor selection signal Stv3 is output. Also,
When the two received light signals Sh and Sv are input at the same time, the determination means 15 determines that the monitor CRT2 has been shot and outputs the monitor selection signal Stv2.

The control unit 12 outputs the sweep signal to the sweep circuit 13 and manages the display range of the target or the like. When the beam reaches the display range of the target, the target is displayed on the beam of the monitor. It is like this.

Further, the control unit 12 waits for the input of the monitor selection signals Stv1 to Stv3 within the scanning time of one screen from the rising timing of the shooting signal, and when the monitor selection signals Stv1 to Stv3 are confirmed, the H The horizontal and vertical count values of the V counter 14 are latched and read, and the scanning position of the beam at the time of shooting, that is, the shooting position is confirmed. Then, the control unit 12
Identifies the monitor based on the monitor selection signals Stv1 to Stv3, and determines whether or not the target is hit by determining whether or not the shooting position is within the display range of the target on the shot monitor. It is like this.

Next, the operation of this ray gun game machine will be described. When the game is started by turning on the light gun game machine for a predetermined time or by inserting a coin by the player, a game screen including targets is displayed on each screen of the monitors CRT1 to CRT3. It is projected. Here, when the player holds the light gun 2 and aims at a target of the monitor CRT1 and pulls a trigger (not shown), a shooting signal is output from the shooting signal generating means 23 and the monitor CRT1 of the monitor CRT1 The light rays from the scanning bright line are the first polarizing filter 11h, the muzzle 20a, and the second polarizing filter 22h.
After that, it is converted into a light reception signal Sh by the light receiving unit 21h.

When the light reception signal Sh is input, the determination means 15
Outputs the monitor selection signal Stv1. The control unit 12
After the shooting signal is input, the monitor CRT1 is identified at the rising edge of the monitor selection signal Stv1 and the two count values of the H / V counter 14 are read. And the control unit 1
On the screen of the monitor CRT1, 2 determines whether or not a hit is made by determining whether or not the shooting position indicated by these two count values is within the display range of the target, and the game progresses according to the result. To do.

Further, when the player shoots toward the screen of the monitor CRT2, the light rays from the scanning bright line of the monitor CRT2 reach the muzzle 20a as natural light and both the second polarizing filters 22h and 22v are passed. The light passes through and is converted into light reception signals Sh and Sv. These two received light signals Sh,
By the input of Sv, the determination means 15 causes the monitor selection signal S
tv2 is output, and the control unit 12 specifies the monitor CRT2 by this input, determines the shooting position, and determines whether or not the target is hit on the same screen.

Further, when the player shoots at the screen of the monitor CRT3, the light receiving signal S from the light receiving portion 21v.
v is output, and the determination unit 15 causes the monitor selection signal Stv3
Is output. The control unit 12 receives the monitor selection signal Stv3
Whether or not the target is hit on the monitor CRT3 screen is determined based on the above.

In the embodiment shown in FIG. 1, if the monitor CRT 2 is not provided, the monitor CRT 2
Since the light rays from the CRT 3 and the CRT 3 are received only by the corresponding light receiving portions, the output of the light receiving signal and the monitor correspond to each other on a one-to-one basis. The game machine can be simplified.

Further, in the embodiment shown in FIG. 1, even when either one of the monitors CRT1 and CRT3 is not provided, the shot monitor can be easily identified. Then, in this case, when the monitor CRT1 is not provided, the mounting of the second polarization filter 22v becomes unnecessary,
When the monitor CRT3 is not provided, the mounting of the second polarization filter 22h becomes unnecessary.

By the way, in the above-mentioned embodiment, the two polarization filters, which are composed of the first polarization filter 11h and the second polarization filter 22h, and the first polarization filter 11v and the second polarization filter 22v, are horizontal and vertical. Are arranged at two kinds of polarization extraction angles. However, it is possible to mount three or more sets of the above-mentioned polarization filters at three or more types of polarization extraction angles. In this case, assuming that the polarization extraction angle between the first polarization filter 11h and the second polarization filter 22h is 0 degree as a reference, a large number of sets of polarization filters are equally divided into an angle range of 180 degrees in one direction from this angle. Will be installed. With this configuration, even if the game screen is configured using many monitors, it is possible to easily identify the fired monitor even though the game screen is relatively simple.

Further, as in the embodiment shown in FIG.
Two 1h, 21v are provided, and the 2nd which is attached to these
When the polarized light extraction angles of the polarization filters 22h and 22v are mounted at an angle difference of 90 degrees, this light gun is provided with an angle detection means for detecting that the rotation has been made by 90 degrees about the barrel 20 as an axis. If the light receiving signals Sh and Sv from the light receiving portions 21h and 21v are exchanged with each other when the rotation of 90 degrees is performed by 90 degrees, the same function as in the above embodiment can be achieved.

Further, an attitude maintaining device composed of a gyro mechanism or the like is provided in the light beam gun 2, and the second polarization filter 2 is provided.
The polarization extraction angles of 2h and 22v are set to the first polarization filter 11
When it is configured to always maintain the same polarized light extraction angle as h and 11v, even if the posture is changed to rotate around the barrel 20, the associated light beam from the monitor is received as a predetermined light reception signal. Can be converted into a light gun game machine having a greater sense of realism by increasing the degree of freedom of the attitude of the light gun 2.
