Next, the electric circuit 5 connected to the target 4 will be described. As shown in FIG. 7, the electric circuit 5 has a stabilizing circuit 20, a decoder 21, and a decision circuit 22, and the decoder 21
Have discriminating means 23 for detecting the individual electrodes 14a, 14b... Whose voltage has changed, and score judging means 24 for determining a score corresponding to the individual electrodes 14a, 14b. The display device 6 and the winning / losing sound generator 27 are connected to the score judging means 24 of the decoder 21 via the judgment circuit 22 having the score storing means 25 and the score comparing means 26.

The electric circuit 5 may be integrated with the target 4 or the display device 6 or may be independent.
And the display device 6 may be formed separately,
27 need not be integral with the display device 6 or the like. In addition, a timer 28 is provided in the electric circuit 5 and a remote control switch is provided.
Equipped with 29 separately.

The function and the like of the electric circuit 5 will be described below. First, in the stabilizing circuit 20, the individual electrodes 14 of the target 4
A stabilizing circuit 20 is additionally provided at the stage of connecting to the electric circuit 5 from a, 14b,..., that is, before the decoder 21 for determining the score.

The stabilizing circuit 20 performs voltage change detection 30 (separately from the decoder 21), voltage amplification 31 and waveform shaping 32. The voltage change in the individual electrodes 14a, 14b. If a necessary signal is obtained, the stabilizing circuit 20 is omitted and the individual electrodes 14a and 14b
And the decoder 21 may be directly connected.

That is, the operation of the stabilizing circuit 20 is based on the individual electrodes 14
The weak and unstable voltage change in a, 14b,... is a voltage (voltage change) that can be logically operated by the subsequent decoder 21. For example, the voltage application electrode 12a of the target 4 and the individual electrode 14a,
When 14b... Are conducted by the arrowhead 2 of the arrow 3, the voltage generation state due to energization is weak or stable due to factors such as deterioration of both electrodes 12a, 14a, 14b. May not.

Therefore, the voltage change detection 30 in the stabilizing circuit 20 detects a slight voltage change (voltage generation), and the voltage amplifier 31 amplifies the detected voltage to a constant voltage that can be logically operated by the subsequent decoder 21. I do. In addition, since the voltage often oscillates even if it is DC due to various factors including external factors, in the waveform shaping 32 in the stabilizing circuit 20, the logic operation of the oscillating voltage waveform is mistaken in the subsequent decoder 21. The voltage waveform is shaped so as not to operate, or to allow logical operation.

Next, the decoder 21 has a plurality of input terminals and a single output terminal, and outputs a determined output signal from the output terminal according to the input terminal to which a signal has been input, from the output terminal to a subsequent determination circuit. Send to 22. The output signal from the decoder 21 is the score areas 52, 52a... (Individual electrodes 14a,
14b...) Is a specific signal (also referred to as a logic voltage as a part) according to the score assigned to it. As an example of the above-mentioned score signal, a pulse such as a square wave (rectangular wave) is formed into a signal of a number corresponding to the score, a voltage is changed to a specific value by changing the number of pulses, or a digital signal is formed. doing.

Although the decoder 21 has been described as having a plurality of input terminals and a single output terminal, both the input terminal and the output terminal may be formed as a plurality, What is necessary is just to have the function of the means 23 and the score determination means 24. For example, a signal may be sent to one output terminal corresponding to a score according to an input signal to the input terminal. Also, when one competitor projects a plurality of arrows 3,
The stabilization circuit 20 interposed between the decoder 21 and the target 4 contributes, detects a voltage change when two arrows 3 are stabbed, sends out an output signal of the total score, At the time of score storage, the total score may be stored.

Next, a decision circuit 22 connected to the decoder 21
Will be described. The judgment circuit 22 is provided to the score judgment means 24 of the decoder 21.
And the score storage means 25
While the score comparing means 26 is connected in series, the score comparing means 26 of the determining circuit 22 is connected to the score determining means 24 of the decoder 21 in parallel with the above flow. And score comparison means
Reference numeral 26 has a function of comparing the scores of signals transmitted before and after from the score storage means 25 of the determination circuit 22 and the score determination means 24 of the decoder 21, respectively.

That is, the first signal sent from the score judgment means 24 of the decoder 21 is received by the score storage means 25 and the score comparison means 26, stored in the score storage means 25, and the second signal is Similarly, the first signal stored in the score storage means 25 and the second signal received from the score determination means 24 of the decoder 21 are received by the score storage means 25 and the score comparison means 26. Are compared. And score comparison means
In 26, only the compared high score signal or the low signal of 0 point is added, and the display device 6 and the winning / losing sound generating device are added.
Send to 27. After the first and second signals are compared and displayed from the decoder 21, the timer 21 or the remote control switch 29 resets the decoder 21.

Further, in the above example, only the higher score signal is transmitted to the display device 6 or the like, but the alternate score may be displayed as it is. In the win / loss sound generator 27, the former or latter victory sound or the latter victory sound or loss sound is produced. Furthermore,
If the scores of the two players are the same, the former will be a winner or a draw.

As shown in FIGS. 8 and 9, in the second embodiment, when the arrow 3 is stabbed in the target 4, displacement and strain caused by a part of the target 4 being compressed and deformed is reduced. It senses and determines the score. Therefore, points different from those of the first embodiment will be described below. The second embodiment also comprises an arrow 3 having an arrowhead 2, a target 4 to be pierced by the arrowhead 3, an electric circuit 5, and a display device 6.
May not be conductive. Also, for target 4,
The electrode layer 12 is not required, and a target 4 is used instead of the individual electrode layer 14.
A plurality of insulating individual elastic deformers 40, 40a... Corresponding to the score areas 52, 52a... Of the surface are provided, and the individual elastic deformers 40, 40a. To the electrical signal, the sensors 41, 41a ... on the outside (back)
Glued. In other words, the essential components of the target 4 are the display of the score areas 52, 52a,... On the surface of the target 4, and the sensors 41, 41a,.
.. Having the elastic deformation members 40, 40a,.

As specific examples of the sensors 41, 41a,.
A strain gauge (also referred to as a strain gauge or a metal wire strain sensor) or a device that detects an electric charge generated by using a substance in which a piezoelectric phenomenon occurs is used. .. Shown in FIG. 9 are strain gauges. A resistance wire 43 whose resistance is changed by an external force is attached to a mount 42 bonded to the individual elastically deformable bodies 40, 40a. Lead wires 44 and 44a are attached. And the sensor 41,
41a... (Lead wires 44, 44a) are connected to a detection circuit (not shown) with one side of the bridge. The detection circuit detects an unbalanced voltage of the bridge. Connected to In the strain gauge according to the second embodiment, the detection operation in the voltage change detection 30 is not a change in presence or absence of a voltage in the first embodiment, but a change in voltage.

Next, the operation of the shooting tool according to the present invention will be described. For example, as shown in FIG.
When the arrow 3 sticks into 2,52a ... C _16, the voltage applying electrode 12a
, And C ₁₆ individual electrodes 14 a, 14 b.
For electrical connection. Then, the individual electrode 14a of C ₁₆
, 14b..., A voltage is generated (voltage change) on the lead wires 16, 16a.

Then, the stabilizing circuit 20 (voltage change detection 30,
Voltage amplification 31, in the waveform shaping 32) detects the voltage change of the C _16, such detection voltage in a subsequent decoder 21 amplifies a constant voltage which can be a logical operation, to shape the voltage waveform.

Then, the discriminating means 23 of the decoder 21 determines which input terminal (which waveform shaping circuit of the stabilizing circuit 20) of the many input terminals has an increased output voltage (which input signal has been generated). Determine. Then, the score judging means 24 of the decoder 21 determines the score of the score area 52, 52a... Corresponding to the waveform shaping circuit (individual electrodes 14a, 14b. Is transmitted to the determination circuit 22 that follows the decoder 21.

The display of the result of the game, which is the operation after the signal is transmitted to the judgment circuit 22, and the like vary depending on the rules.
Representative examples will be described below. When the determination circuit 22 receives the logic voltage (score signal), the score is displayed in the column A of the display device 6, and the hit sound struck by the arrow 3 is emitted from the win / loss sound generator 27. Next, the decoder 21 is reset by the timer 28 or the remote control switch 29 before the opponent projects. Then, the score of the arrow 3 projected by the competitor is detected in the same manner as described above, the score is displayed in the second competitor column (column B), and a hit sound is emitted. Such a game is repeated five times in the case shown in the figure, and the competitor or the like successively confirms the win or loss.

The electric circuit 5 of the embodiment having the judgment circuit 22 also performs automatic judgment and display of winning or losing. For example, the score storage means 25 in the determination circuit 22 that receives the logic voltage (score signal) corresponding to the score of the former stores the logic voltage corresponding to the score, and emits a display and a hit sound. Then, the score of the latter projected arrow 3 is detected and determined, and is output as a logical voltage from the decoder 21. The score comparing means 26 compares the score (logical voltage) of the former stored in the score storing means 25 with the decoder. Compare the latter score (logic voltage) received from 21. When the score of the latter is higher than the score of the former, the score of the latter is displayed, and the score of the former is deleted, and at the same time, the winner sound is emitted from the win / loss sound generator 27. Conversely, when the score of the latter is lower than or equal to the score of the former, the loser sound is emitted from the win / loss sound generator 27 while the score display of the former is kept as it is. Although the score of the first player is always displayed, the score may be displayed only when the winner is determined.

Next, the operation of the shooting tool according to the second embodiment will be described with respect to differences from the first embodiment. As shown in FIG. 8, when the arrow 3 pierces the target 4, the target 4
The arrowhead 2 of the arrow 3 enters any one of the individual elastic deformation bodies 40, 40a, and the individual elastic deformation bodies 40, 40a,. As a result, an external force acts on the resistance wires 43 of the sensors 41, 41a, which are adhered to the individual elastically deformable bodies 40, 40a, so that the resistance changes, and is detected as an unbalanced voltage by a bridge detection circuit. Thereafter, display and the like are performed by the electric circuit 5 in the same manner as in the first embodiment. Since the voltage change in the sensors 41, 41a... Is a minute change, the connection to the determination circuit 22 is preferable to the direct connection to the decoder 21.

Further, in the above embodiment and FIG. 1, the target 4 and the display device 6 are integrated and the target 4 and the display device 6 are connected 1: 1. Can be appropriately changed (hereinafter, not shown). For example,
The target 4 and the display device 6 may be separated from each other, and both may be electrically connected. Further, the score display column (FIG. 1) may be used to increase the size of the display device 6 or to accommodate the number of competitors. A, B
Columns) can be increased or a plurality of targets 4 and one display device 6 can be connected. And the installation position of the display device 6 separated from the target 4 is not limited to the vicinity of the target 4,
The position should be easy for all athletes (shooters) and related parties to confirm. In addition, in the electrical connection between the target 4 and the display device 6, a wired system may be used, or a transmitter and a receiver may be respectively provided to use wireless signal transmission and reception, and some lead wires may be omitted. Is also good. In some score displays, individual scores and total scores for each competitor are displayed without performing a score comparison.

Although the target 4 has been described focusing on the fixed one and the concentric dividing lines 50, 50a, etc., such an arrangement can also be changed. For example, the target 4 may be formed in a circular shape, and radial dividing lines 51, 51a... May be provided, and the target 4 may be further rotated. In the electrical connection between the rotating target 4 and the display device 6, a wireless method is employed, or a plurality of circumferential terminals are provided on a rotating shaft (rotating body) of the target 4, and a brush is externally connected to the terminal. The signal may be transmitted and received from the target 4 to the display device 6 by making contact. The signal to the terminal provided on the rotating body of the target 4 is preferably a processed signal after the stabilizing circuit 20 or the decoder 21 which is a stable signal. In this way, if the target 4 is rotated, the competitiveness is reduced. However, if the score is replaced with a numerical value, a plurality of targets 4 are set, and the numerical value is sequentially displayed on the display device 6, the lightning display of the hit location is displayed. It can be applied to a lottery device used, and the shooting tool 1 of such an application example also belongs to the present invention.

In short, the present invention comprises an arrow 3 having a conductive arrowhead 2, a target 4 to be pierced by the arrow 3, an electric circuit 5, and a display device 6, so that the target 4 is away from the projection position. Since the display device 6 displays the state where the arrow 3 is stabbed, in particular, the level of the score, the player can easily confirm the victory or defeat of the competitor from a distance. The target 4 has at least two electrode layers 12, 14 with an insulating layer 13 interposed therebetween, and at least one electrode layer 14 corresponds to the score areas 52, 52a,.

Whose voltage has changed, and a score judging means 24 for determining a score corresponding to the individual electrodes 14a, 14b. Since the display device 6 is connected to the score judging means 24, the same score as the score displayed on the surface of the target 4 is displayed on the display device 6, and the hit position (score) of the arrow 3 can be easily confirmed. I can do it.

The display means of the score areas 52, 52a... Is not limited, and the decoration of the display layer 10 can be easily performed, and the pedestal layer 15 can be used for the arrangement of the lead wires 16, 16a. Can be performed.

The target 4 is composed of five layers. The display layer 10, the electrode layer 12 to which a voltage is applied, the insulating layer 13,
Since the individual electrode layer 14 and the pedestal layer 15 are formed,
Arrow 3 piercing 14 is a relatively thin part at the tip,

Numerous insulating individual elastic deformation bodies 40 and 40a corresponding to ...
, And a sensor 4 for converting the strain when the arrow 3 is stabbed into the individual elastically deformable bodies 40, 40a to an electric signal.
Because the sensors 41, 41a are connected to the electric circuit 5, the individual elastically deformable bodies 40, 40a are deformed when the arrow 4 is inserted into the target 4, and the hit of the arrow 3 is confirmed. Since the arrow 3 does not need to be inserted into the sensors 41, 41a,..., The life of the target 4 can be extended.

Since the target 4 and the display device 6 are integrated,
The shooting tool 1 is made compact, so that shooting and preparation for the game can be facilitated, and the indoor game such as at home can be fully enjoyed.

Since the target 4 and the display device 6 are separated,

You can instantly check whether or not it is exciting.

Further, since the arrow 3 is provided with the stopper 7, when the arrow 3 having a strong propulsion pierces the target 4, it can be prevented from penetrating or stopped at an appropriate position on the detection layer 11. Therefore, the detection layer 11, the lead wires 16, 16a ..., the sensors 41, 41
a… etc. can be prevented.

Also, since the target 4 is freely rotatable, the hit position is not aimed at and the chance becomes high. If this accident is used, it is used as a lottery device and the display device 6 is used.
The practical effect is enormous, for example, the hit result and the lottery result can be displayed to easily confirm the hit position.
