And a display output control unit 13 for displaying the shooting result score in the score calculation unit 12 according to the type of the target plate recognized by the target plate recognition unit 15. Is set.

Here, the position detecting optical element serving as the landing position detecting section 11 is composed of a condenser lens and a position detecting semiconductor element, and the position detecting semiconductor element is a CCD (Charge Coupled Device). ) And PSD (Posit
Ion Sensitive Detector) is known, but PSD is more preferably used than CCD from the viewpoint of cost and detection speed.

In the target device 1 configured as described above, when the landing position detection signal included in the light source 3 emitted from the laser gun 2 lands on the target plate 4, the PSD provided in the landing position detection unit 11 By its landing position (x,
y) is detected. Here, x and y are coordinate values of rectangular coordinates on the target plate 4.

In the score calculation unit 12, the origin of this landing position (x, y) is made to correspond to the origin O of the target plate 4, and the distance from that origin to the landing position (x, y) is calculated, The score at that time is calculated by determining which score area the landing position (x, y) is.

In the display output control unit 13, the landing position information detected by the landing position detection unit 11 and the score calculated by the score calculation unit 12 are output by the display output unit 14 including an LED or the like. To be done.

The PSD device has a two-dimensional current generating film. If the coordinate position of the light spot where the laser beam is focused on the two-dimensional current generating film by the condenser lens is (x, y), the two-dimensional current generating film is two-dimensional at the coordinate position (x, y). A linearly and linearly corresponding current is generated in the membrane.

First, two currents in opposite directions (current values are Ix1 and Ix2, respectively) are generated in the x-axis direction, and two currents in opposite directions (current values are also indicated in the y-axis direction). Iy1 and Iy2) are generated.
Then, the coordinate position (x, y) has a coefficient k and a current value Ix.
It is calculated as follows using 1, Ix2, Iy1 and Iy2.

X = k (Ix2-Ix1) / (Ix2 + Ix1) (1) y = k (Iy2-Iy1) / (Iy2 + Iy1) (2) Here, light in which both Ix2-Ix1 and Iy2-Iy1 are zero. The point position is defined as the electrical and mechanical coordinate origin (0,0) of the PSD. The target plate 4 needs to be two-dimensionally positioned with an accuracy within an allowable range specified for PSD.

The method of recognizing the target plate 4 by the target plate recognition unit 15 will be described in detail below.

As a method of recognizing the type of the target plate 4 attached to the target device 1, for example, a changeover switch capable of setting the type of the target plate 4 attached to the target device 1 is provided in the target device 1, It is conceivable that the type of the target plate 4 attached to the target device 1 is set by the changeover switch, and thereby the type of the target plate 4 attached to the target device 1 is recognized.

In the score calculation unit 12, an arithmetic expression for obtaining a score from the landing position is set according to the type of the target plate 4 set by the changeover switch.

As a result, the score according to the type of the target plate 4 on which the target device 1 is mounted is accurately displayed on the display output unit 14.

As another method, the target plate recognition unit 15 may automatically recognize the type of the target plate 4 attached to the target device 1.

FIG. 4 is a diagram for explaining an example of the configuration of the target plate recognition unit 15 shown in FIG.

As shown in FIG. 4, the target plate recognition unit 15 in this example recognizes the type of the target plate 4 by detecting the resistance value of the resistor 22 built in the target plate 4.
And a pull-up resistor 21 connected to one end of the resistor 22 and the recognition unit 23, and the other end of the resistor 22 is grounded. In addition, the resistor 22 built in the target plate 4
Has a different resistance value for each type of the target plate 4, and when the target plate 4 is attached to the target device 1, the target plate recognition unit 1
5 is connected.

The target plate recognition section 15 constructed as described above
In, when the target plate 4 is attached to the target device 1, the recognition unit 23 detects the resistance value of the resistor 22 built in the target plate 4, and the type of the target plate 4 is recognized based on the detection result. To be done. Therefore, the recognition unit 23 needs to store the resistance value of the resistor 22 for each type of the target plate 4.

When the recognition unit 23 recognizes the type of the target plate 4, the information is sent to the score calculation unit 12, and the score calculation unit 12 recognizes the type of the target plate 4 recognized by the recognition unit 23. Based on this, a calculation formula for calculating the score is set.

In this way, if the type of the target plate 4 attached to the target device 1 is automatically recognized, the score is calculated according to the type of the target plate 4 attached to the target device 1. Since the calculation formula for will be set automatically,
When the target plate 4 attached to the target device 1 is changed, the user does not need to set the type of the target plate 4, the burden on the user is reduced, and an error in setting the target plate type is prevented. can do.

In the above-mentioned one, the target plate 4
The type of the target plate 4 attached to the target device 1 is recognized by detecting the resistance value of the resistance built in the target device 1. However, information for identifying the target plate 4 is written on the target plate 4. The IC chip is built in, and the target plate 4 is the target device 1.
The target plate 4 attached to the target device 1 by reading the information written in the IC chip when it is attached to the target plate 4, and the target plate 4 can be identified by the target plate 4. It is also possible to detect the type of the target plate 4 attached to the target device 1 by reading the magnetic information from the target plate 4 when the target plate 4 is attached to the target device 1 by writing Conceivable. Also,
When the target plate 4 is provided with slits having a different pattern for each target plate 4, and when the target plate 4 is attached to the target device 1, the arrangement pattern of the slits provided on the target plate 4 is set. It is also conceivable to detect the type of the target plate 4 mounted on the target device 1 by optically reading.

As described above, since the calculation formula for calculating the score in the score calculation unit 12 is set according to the type of the target plate 4 recognized by the target plate recognition unit 15, the score calculation unit In 12, the calculation formula for calculating the score is registered for each type of the target plate 4.

The series of processes described above may be performed by a computer program.

The structure of the target device 1 described above will be described below with reference to a plurality of examples.

FIG. 5 is a front view showing an example of the structure of the target device shown in FIGS. 1 and 3. In this target device 1, the surface on which the target plate 4 is installed, that is, the surface facing the shooting seat where the shooter is located is the front surface.

As shown in FIG. 5, the front surface of the target device 1 in this example is a square 10 cm long and 10 cm wide. A square target plate 4 is also mounted on the central portion of the front surface of the target device 1. A circular scoring area 6 as shown in FIG. 2 is provided at the center of the target plate 4. The target plate 4 is screwed by four screw fastening portions 5.

Around the target plate 4 mounted on the target device 1, eight light-emitting bodies which are the display output section 14, that is, L consisting of light-emitting diodes (hereinafter referred to as LEDs) 9 _{1 to} 9 _{8 are provided.}
An ED group 9 is arranged. Each LED 9 _{1 of the} LED group 9
To 9 ₈ are arranged at substantially equal intervals around the target plate 4 mounted on target device 1. Specifically, 8 L
The ED9 _{1 to} 9 ₈ are located at the respective LEDs 9 _{1 to} 9 ₈ from the center of the target plate 4.
The straight lines (shown by the alternate long and short dash line in FIG. 5) extending in the direction are arranged so that the angle formed by the adjacent straight lines is 45 ° which is a predetermined angle.

In the target device having the above-mentioned structure, the LED group 9 is used to display the score.

When the laser light emitted from the laser gun 2 lands on the target plate 4, first, in the landing position detection section 11 provided in the target device 1, the above-mentioned formula (1),
The landing position (x, y) of the laser light is detected using (2), and the detected landing position (x, y) is sent to the score calculation unit 12 provided in the target device 1.

The target plate recognition unit 15 recognizes the type of the target plate 4 attached to the target device 1, and the score calculation unit 12 recognizes the type of the target plate 4 attached to the target device 1. A calculation formula for calculating the score is set.

In the score calculation unit 12, based on the landing position (x, y) detected by the landing position detection unit 11,
The distance from the origin O to the landing position (x, y) is calculated,
The score is calculated based on the distance and a calculation formula set according to the type of the target plate 4 attached to the target device 1. It should be noted that the origin O of the target plate 4 and the detection origin of the landing position detection means must be completely coincident with each other.

The score information calculated by the score calculation unit 12 is sent to the display output control unit 14 provided in the target device 1, and the display output control unit 14 displays the score information calculated by the score calculation unit 12. Based on each LED 9 _{1 of the} LED group 9
The lighting pattern for ~ 9 ₈ is set. For example, when the score calculated by the score calculation unit 12 is _1, only the LED 9 ₁ is turned on under the control of the display output control unit 14. Similarly, when the score calculated by the score calculation unit 12 is 2 to 8, the display output control unit 14
The LEDs 9 _{2 to} 9 ₈ are turned on by the control described above. That is, in this example, the LED to be turned on changes according to the score calculated by the score calculation unit 12.

Accordingly, for example, when only the LED 9 ₅ is lit, the shooter can recognize that the score of the shooting result this time is 5.

Further, in this example, the score calculation unit 12
If the score calculated in step 9 is 9, the LED 9 ₂ and the LED 9 ₇ are turned on under the control of the display output controller 14. When the score calculated by the score calculation unit 12 is 10, all the LEDs 9 _{1 to} 9 ₈ are turned on by the control of the display output control unit 14. That is, in this example, the combination of the LEDs that are turned on changes according to the score calculated by the score calculation unit 12.

As a result, where normally at least 10 LEDs are required to display 0 to 10 points, some points are expressed by changing the combination of LEDs to be turned on. The number can be reduced from 10 to 8.

In this example, the LEDs are turned on from the lower left of the target plate 4 counterclockwise as the score increases, but the present invention is not limited to this.
Other lighting patterns such as clockwise and binary numbers may be adopted. In the present invention, any lighting pattern may be adopted as long as the shooter can read the score from the lighting pattern.

Further, although the target plate 4 is a plate-shaped target plate in this example, it may be a film or a paper-shaped member.

FIG. 6 is a front view showing another structural example of the target device shown in FIGS. 1 and 3. In addition, this target device 1
Then, the surface on which the target plate 4 is installed, that is, the surface facing the shooting seat on which the shooter is located is the front surface.

Around the target plate 4 mounted on the target device 1, an LED group 9 composed of _eight LEDs 9 _{1 to} 9 ₈ serving as the display output section 14 is arranged. In this example, straight lines extending from the center of the target plate 4 to the LEDs 9 _{1 to} 9 ₈ (see FIG. 6).
(Shown by the alternate long and short dash line), the eight LEDs 9 are arranged so that the angle formed by the adjacent straight line is 45 ° which is a predetermined angle.
_{1 to} 9 ₈ are the same as the target device shown in FIG.

In this example, the eight LEs of the LED group 9 are
D9 _{1 to} 9 ₈ are used to display the approximate landing position on the target plate 4, not the score.

When the laser light emitted from the laser gun 2 lands on the target plate 4, first, in the landing position detection section 11 provided in the target device 1, the above-mentioned formula (1),
The landing position (x, y) of the laser light is detected using (2), and the detected landing position (x, y) is sent to the display output control unit 13 provided in the target device 1.

Here, for example, assuming that the landing position of the target plate 4 is the point A shown in FIG.
Assuming that the line segment OA is a line segment OA, as shown in FIG.
The point A is between a line segment OB extending from the origin O to the LED 9 ₄ and a line segment OC extending from the origin O to the LED 9 ₅ . Further, the angle θ ₁ formed by the line segment OA and the line segment OB is smaller than the angle θ ₂ formed by the line segment OA and the line segment OC.

In the display output control unit 13, the target plate 4
The line segment OB extending from the origin O to the LED 9 ₄ has the smallest angle with the line segment OA connecting the point A, which is the landing position, and the origin O of the target plate 4, and therefore the LED 9 on the line segment OB Turn on ₄ .

As described above, in this example, the LEDs in the LED group 9 are controlled by the display output controller 13.
Among 9 _{1 to} 9 ₈ , the LED having the smallest angle between the line segment extending from the origin O to the LED and the line segment extending from the origin O to the landing position is turned on. In other words, the target device 1 of this example has eight Ls arranged at equal intervals around the target plate 4.
The scoring area of the target plate 4 is divided into eight equal-angle (45 °) areas centered on the origin O by the ED 9 _{1 to} 9 ₈ and the target board 4
It is operated to find out which one of the eight divided areas the upper landing position belongs to and to turn on the LED on the area side.

As a result, the shooter can confirm in which direction the landing position on the target plate 4 deviates from the origin O, which is the center of the target plate 4, from the firing point.
Generally, in such a shooting competition, the landing positions are generally concentrated in a score region of 10 to 7 points, that is, a region near the origin O. Therefore, for the shooter, rather than the amount of deviation of the landing position from the origin O,
The direction of the landing position from the origin O, that is, the shift direction is more important information for correcting the shooting operation.
In this example, by displaying the displacement direction as the shooting result, the displacement direction of the landing position can be transmitted to the shooter, and the shooter confirms the displacement direction and corrects the shooting motion. .

Note that, as described above, the LED is based on the line segment connecting the landing position on the target plate 4 and the origin of the target plate.
Instead of setting the lighting pattern of 9 _{1 to} 9 ₈ simply by lighting the LED having the shortest linear distance to the point A at the landing position among the LEDs 9 _{1 to} 9 ₈ in the LED group 9, The shooting position may be notified to the shooter.

FIG. 7 is a front view showing another structural example of the target device shown in FIGS. 1 and 3. In addition, this target device 1
Then, the surface on which the target plate 4 is installed, that is, the surface facing the shooting seat on which the shooter is located is the front surface.

Around the target plate 4 mounted on the target device 1, an LED group 9 composed of _eight LEDs 9 _{1 to} 9 ₈ serving as the display output section 14 is arranged. In this example, straight lines extending from the center of the target plate 4 to the LEDs 9 _{1 to} 9 ₈ (see FIG.
(Shown by the alternate long and short dash line), the eight LEDs 9 are arranged so that the angle formed by the adjacent straight line is 45 ° which is a predetermined angle.
_{1 to} 9 ₈ are the same as the target device shown in FIG.

In this example, the eight LEs of the LED group 9 are
D9 _{1 to} 9 ₈ are used to display the approximate landing position on the target plate 4, not the score.

When the laser light emitted from the laser gun 2 lands on the target plate 4, first, in the landing position detection section 11 provided in the target device 1, the above-mentioned formula (1),
The landing position (x, y) of the laser light is detected using (2), and the detected landing position (x, y) is sent to the display output control unit 13 provided in the target device 1.

Here, for example, assuming that the landing position of the target plate 4 is the point A shown in FIG.
Assuming that the line segment OA is a line segment OA, as shown in FIG.
The point A is between a line segment OB extending from the origin O to the LED 9 ₄ and a line segment OC extending from the origin O to the LED 9 ₅ . Further, the angle θ ₁ formed by the line segment OA and the line segment OB is smaller than the angle θ ₂ formed by the line segment OA and the line segment OC.

In the display output control unit 13, the target plate 4
The line segment OB extending from the origin O to the LED 9 ₄ has the smallest angle with the line segment OA connecting the point A, which is the landing position, and the origin O of the target plate 4, and therefore the LED 9 on the line segment OB Turn on ₄ .

Further, in the display output control unit 13, the difference between the angle θ ₁ and the angle θ ₂ is 11.25 ° which is a predetermined angle.
In the following cases, not only the LED 9 ₄ but also the LED 9 ₅ is turned on.

[0151] Thus, in the present embodiment, the control in the display output control unit 13, among the LED 9 ₁ to 9 ₈ in the LED group 9, a line segment extending from the origin O to the LED 9 ₁ to 9 ₈ and the origin O From the LED (first illuminant, here LE), the angle formed by the line segment OA extending from the impact position to the landing position (point A) is the smallest (first angle, here θ ₁ ).
LED whose angle between D9 ₄ ) and the straight line OA is the second smallest angle (second angle, here θ ₂ ) after the first angle.
(Second illuminant, here LED 9 ₅ )
While the first light emitter (LED9 ₄ ) lights up,
When the difference between the angle and the second angle is equal to or less than the predetermined angle, the second light emitter (LED9 ₅ ) is also turned on.

As a result, the shooter has the LED 9 ₄ and the LE.
By seeing that D9 ₅ is lit, it can be recognized that the landing position is displaced in the direction between the LED 9 ₄ and the LED 9 ₅ .

In this example, the predetermined angle is set to 11.25.
If the angle is 0, the scoring area of the target plate 4 can be divided into 16 equal-angled areas (22.5 °) centering on the origin O, whereby the number of LEDs is as shown in FIG. With the same number, the resolution of the direction display of the landing position with respect to the center of the target plate 4 can be doubled, that is, divided into 16 parts.

As described above, in the target device shown in FIGS. 5 to 7, the LE having the lighting pattern which changes around the mounted target plate 4 according to the impact result such as the score and the impact position.
Since the D group 9 is provided and the landing result is displayed by the simple lighting pattern of the LED group 9, even when the display device for displaying the landing result is not installed near the firing point. A shooter who is far away from the target can easily recognize the impact result.

FIG. 8 is a front view showing another structural example of the target device shown in FIGS. 1 and 3. In addition, this target device 1
Then, the surface on which the target plate 4 is installed, that is, the surface facing the shooting seat on which the shooter is located is the front surface.

Around the target plate 4 mounted on the target device 1, the LED group 8 which is the first luminous body group consisting of the eight LEDs 8 ₁ to ₈ 8 and serves as the display output section 14, LED
An LED group 9 which is a second luminous body group including 9 _{1 to} 9 ₈ is arranged. The LED group 8 is an LED group for displaying the score calculated by the score calculation unit 12, and is L
The ED group 9 is an LED group for displaying the landing position detected by the landing position detection unit 11.

Further, the LEDs 8 ₁ to 8 ₈ and the LEDs 9 _{1 to} 9 ₈ are the same as those shown in FIGS. 5 and 6, each line segment extending from the center of the target plate 4 to each LED 9 (the one-dot chain line in FIG. 8). ) Is arranged such that the angle formed by the adjacent line segment is 45 ° which is a predetermined angle. Further, although the LED group 9 is arranged outside the LED group 8 in the present example, the LED group 9 may be arranged in the opposite manner.
The arrangement relationship with the ED group 9 is not limited.

The LED groups 8 and 9 have different emission colors. For example, applying the red diode in LED 8 ₁ to 8 ₈ of LED group 8, LED 9 ₁ ~ LED group 9
A green diode is applied to 9 ₈ .

This makes it possible to prevent the shooter from erroneously recognizing the score display and the landing position display.

In this example, L for displaying a score is displayed.
The lighting pattern of the ED group 8 is the same as that shown in FIG. 5, and the lighting pattern of the LED group 9 for displaying the landing position is the same pattern as that shown in FIG. 6 and FIG. , 9 are controlled.

FIG. 9 is a front view showing another structural example of the target device shown in FIGS. 1 and 3. In addition, this target device 1
Then, the surface on which the target plate 4 is installed, that is, the surface facing the shooting seat on which the shooter is located is the front surface.

As shown in FIG. 9, in this example, the score calculated by the score calculation unit 12 is displayed around the mounted target plate 4 and detected by the landing position detection unit 11. An LED group 19 for displaying the landing position is provided. In the LED group 19, when the score calculated by the score calculation unit 12 is displayed, the score calculated by the score calculation unit 12 is displayed. Based on the lighting pattern set by the display output control unit 13, the score is displayed, and when the landing position detected by the landing position detection unit 11 is displayed, it is detected by the landing position detection unit 11. The landing position is displayed in the lighting pattern set by the display output control unit 13 based on the landing position.

In the display output control unit 13, the display in the LED group 19 is executed in time division by the score display and the landing position display. Further, it is preferable that the display on the LED group 19 is intermittently alternated between the score display and the landing position display.

The LEDs 19 _{1 to} 19 ₈ of the LED group 19 are
It is a two-color light emitting diode having two types of light emission colors. For example, if the LEDs 19 _{1 to} 19 ₈ are diodes that emit two colors, red and green, the display output control unit 1
In 3, when displaying the score calculated by the score calculation unit 12, the LEDs 19 _{1 to} 19 ₈ emit red light,
When displaying the landing position detected by the landing position detection unit 11, the LEDs 19 _{1 to} 19 ₈ are set to emit green light.

In this way, the LED 19 is displayed in the display output control unit 13 when the score calculated by the score calculation unit 12 is displayed and when the landing position detected by the landing position detection unit 11 is displayed. if a light emission color different from those in the _{1-19 8,} gunners, and a score display and landing position display can be easily identified.

In this example, the lighting pattern of the LED group 19 for displaying the score is set to the same pattern as that shown in FIG. 5, and the LE for displaying the landing position is displayed.
The display in the LED group 19 is controlled by setting the lighting pattern of the D group 19 to the same pattern as that shown in FIGS. 6 and 7.

As described above, in this example, one LED group 1 is used by using the two-color light emitting diodes.
Since both the score and the landing position are displayed at 9, it is possible to reduce the number of LEDs as compared with the one shown in FIG. 8, thereby reducing the cost of the device and the device. It can be miniaturized.

FIG. 10 is a front view showing another structural example of the target device shown in FIGS. 1 and 3. In this target device 1, the surface on which the target plate 4 is installed, that is, the surface facing the shooting seat where the shooter is located is the front surface.

In this example, at least one LED, for example, LEDs 9 _{1 to} 9 ₃ in the LED group 9 provided around the target plate 4 of the target device 1 shown in FIG. By control, it operates as a ready lamp indicating that it is possible to fire.

The LED, which operates as a ready lamp indicating that shooting is possible, is preferably arranged on the lower side of the target plate 4. When the LEDs 9 _{1 to} 9 ₃ which also function as the ready lamps are arranged below the target plate 4, the LEDs 9 _{1 to} 9 ₃ become blind spots by the barrel of the laser gun 2 when the shooter holds the gun. Since it is no longer in the view of the shooter, it prevents the ready lamp from interfering with the shooter's shooting. Also, if the lighting brightness when operating as a ready lamp is controlled to be smaller than the lighting brightness during other operations, the ready lamp impairs the concentration of the shooter when the shooter shoots. It is avoided that it is lost.

At least one of the LED groups 9 provided around the target plate 4 of the target device 1 shown in FIG.
Under control of the display output control unit 13, the three LEDs, for example, LEDs 9 _{5 to} 9 ₇ operate as a busy lamp indicating that shooting is not possible.

The LED operating as a busy lamp indicating that shooting is not possible is preferably arranged above the target plate 4. If LEDs 9 _{5 to} 9 ₇ which also function as busy lamps are arranged above the target plate, even when the shooter holds the gun, the LEDs 9 _{5 to} 9 ₇ are in the field of view of the shooter, and therefore shooting is not possible. This can be easily recognized by the shooter.

As described above, in this example, the LED
Since the LEDs 9 _{1 to} 9 ₈ forming the group 9 also serve as ready lamps or busy lamps, it is not necessary to dispose another ready lamp or busy lamp, and the number of LEDs can be reduced.

FIG. 11 is a front view showing another structural example of the target device shown in FIGS. 1 and 3. In this target device 1, the surface on which the target plate 4 is installed, that is, the surface facing the shooting seat where the shooter is located is the front surface.

As shown in FIG. 11, in this example, a seven-segment type score display plate 30 for displaying the score calculated by the score calculation unit 12 is arranged in the vicinity of the area where the target plate 4 is mounted. It is set up. The seven segment type score display plate is a score display plate in which seven LEDs are arranged so as to form a figure eight, and those LEDs are visually recognized as they are as numbers showing the score at that time. It is a display board that lights up.

When the laser light emitted from the laser gun 2 lands on the target plate 4, first, in the landing position detection section 11 provided in the target device 1, the above-mentioned formula (1),
The landing position (x, y) of the laser light is detected using (2), and the detected landing position (x, y) is sent to the score calculation unit 12 provided in the target device 1.

Further, the target plate recognition unit 15 recognizes the type of the target plate 4 mounted on the target device 1, and the score calculation unit 12 recognizes the type of the target plate 4 mounted on the target device 1. A calculation formula for calculating the score is set.

In the score calculation unit 12, based on the landing position (x, y) detected by the landing position detection unit 11,
The distance from the origin O to the landing position (x, y) is calculated,
The score is calculated based on the distance and a calculation formula set according to the type of the target plate 4 attached to the target device 1.

The score information calculated by the score calculation unit 12 is sent to the display output control unit 14 provided in the target device 1, and the display output control unit 14 displays the score information calculated by the score calculation unit 12. Based on the score display plate 30, L
The lighting pattern of the ED is controlled, and the score calculated by the score calculation unit 12 is displayed as it is on the score display plate 30.

If the target device 1 as described above is used, FIG.
Unlike the shooting system shown in 6, it is not necessary to provide a display device such as a display device for displaying a score near the shooting seat, and it is possible to perform shooting training even in a relatively narrow place. .

In the target device of this example, not only a score display plate for displaying the score but also a landing position display plate for displaying the landing position in characters can be considered.

FIG. 12 is a perspective view showing another structural example of the target device shown in FIG.

It is a square with a width of 10 cm and a width of 10 cm. A square target plate 4 is also installed at the center of the front of the target device 1. A circular score area as shown in FIG. 2 is provided in the central portion of the target plate 4. The target plate 4 is
It is screwed by four screw fastening portions 5.

On the side surface of the target device 1 on which the target plate 4 is installed, when the laser beam 3 emitted from the laser gun 2 lands on the target plate 4, it is calculated based on the landing position and the landing position. A speaker 17 that outputs the score obtained by voice or electronic sound is installed. The speaker 17
The position where the target plate 4 is installed is not limited to the side surface of the target device 1 and may be a region where the target plate 4 is not installed.

FIG. 13 is a block diagram showing the structure of the internal circuit of the target device 1 shown in FIG.
