Abstract

PURPOSE:To provide the hand wrestling game machine which can prevent a throw fracture of a player. CONSTITUTION:A turning arm 5 is provided so as to turnable in the forward and the backward directions. A torque motor 13 imparts turning torque in the forward direction to its turning arm 5. When turning torque in the backward direction against the turning torque in the forward direction imparted to the turning arm 5 is applied to the turning arm 5, a speed detecting means constituted of a sensor plate 14, a photosensor 15 and a CPU detects magnitude of turning angular velocity in its backward direction. In the case the magnitude of the turning angular velocity detected by the speed detecting means exceeds a specific value, the CPU decreases an output of the torque motor 13 to the specific value. In such a way, when a player applies suddenly large force to the turning arm, the turning torque in the forward direction of the turning arm 5 decreases suddenly, immediately before his own humerus is subjected to torwion fracture (throw fracture) due to a sudden contraction of the biceps and the triceps of the player. Therefore, throw fracture can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arm-wrestling game machine.

[0002]

2. Description of the Related Art In a conventional arm-wrestling game machine, a synthetic resin rotating arm is also provided to an opponent who is three-dimensionally formed of synthetic resin. A torque motor for applying a turning torque is provided on the turning arm, and the turning arm is turned with a constant turning torque at the same time when the game is started. The player wins if the player tilts the turning arm against the turning torque by a predetermined angle, and if the player's arm is tilted by the turning arm by a predetermined angle, the player wins. The rules are set so as to lose.

[0003]

By the way, particularly when a player suddenly applies a large force to the rotating arm at the start of a game and the rotating arm does not move, a phenomenon called throwing bone fracture. Could happen.

This is because when the player applies a sudden force to the rotating arm, the biceps brachii and the triceps brachii are controlled so that they do not expand or contract so that the humerus is not overloaded. When you have to, you're out of control because of sudden muscle contractions. In other words, the humerus is a phenomenon in which the humerus fractures in a twisted shape due to an overload caused by its own muscle contraction, which often occurs during baseball pitching.

The present invention has been made to solve the above problems, and an object thereof is to provide an arm-wrestling game machine capable of preventing a player's throwing bone fracture.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a rotating arm that is rotatable in forward and reverse directions, and applies a rotating torque in a forward direction to the rotating arm. And a rotational speed in the reverse direction of the rotating arm when a reverse rotational torque against the forward rotational torque applied to the rotational arm is applied to the rotational arm. A speed detecting means for detecting the speed of the torque generating means, and an output control means for decreasing the output of the torque generating means to a predetermined value when the magnitude of the rotational speed in the reverse direction detected by the speed detecting means is a predetermined value or more. The point is to have

[0007]

Therefore, according to the present invention, when a turning torque in the opposite direction against the turning torque in the forward direction applied to the turning arm is applied to the turning arm, the turning torque of the turning arm in the opposite direction is increased. When the rotation speed is equal to or higher than the predetermined value, the forward rotation torque applied to the rotation arm is reduced to the predetermined value.

Therefore, when the player suddenly applies a large force to the turning arm, the player applies the turning torque in the positive direction applied to the turning arm to the turning arm. Can be reduced to a value where the reaction of does not affect the player's bones and cause a fracture.

Further, when the player applies a slow and strong force to the rotating arm without the risk of throwing bone fracture, the positive rotating torque applied to the rotating arm is applied according to a normal program. , Players can fully enjoy the arm-wrestling game.

On the other hand, an elbow pad 7 for attaching the elbow to the player is attached to the support base 6 at a position where the elbow 5a of the rotating arm 5 is located. A cushion body 8 for preventing injury of the player's hand is provided at two places on the left and right sides of the elbow pad 7.
Is provided. On the right side of the upper surface of the support base 6, a start switch 9 for starting a game and a CRT 3
A plurality of selection switches 10 for selecting an opponent displayed on the screen are provided. Further, on the left side of the upper surface of the support base 6, a grip 11 which a player holds is provided in a protruding manner.

As shown in FIG. 2, the rotary shaft 12 of the rotary arm 5 is shown.
Is directly connected to a torque motor 13 as a torque generating means arranged and fixed in the machine body 1.
By this, a positive (right) turning torque is applied to the turning arm 5. A sensor plate 14 having a plurality of recesses 14a formed at a predetermined pitch on the outer periphery is fixed to the rotating shaft 12, and a photosensor 15 is arranged so as to sandwich the sensor plate 14.

A pressure sensor 16 is built in the palm of the rotary arm 5, and when the player holds the palm of the rotary arm 5, the pressure sensor 16 outputs a motor start signal. In addition, a wire 18 for closing the fingertip of the rotating arm 5 is inserted through the guide plate 17 fixed to the rotating arm 12, and its end portion is wound and unwound by a winding shaft (not shown). Has become.

Next, the electrical construction of this embodiment will be described with reference to FIG. The CPU 20 as a torque control unit includes a ROM 21 that stores a control program and a RAM 22 that temporarily stores a calculation processing result and the like. ROM21
In addition to the control program, the image data displayed on the CRT 3, the voice data emitted from the speaker 4, and the like are stored in.

A start switch 9 and a selection switch 10 are connected to the CPU 20. And the CPU 20
On the basis of the ON operation of the start switch 9
The initial screen of is displayed. Further, the CPU 20 reads the display data corresponding to the selected opponent from the ROM 21 based on the ON operation of the selection switch 10, and displays the selected opponent on the CRT 3.

A photo sensor 15 is connected to the CPU 20. Then, the CPU 20 counts the number of detection pulses output from the photosensor 15 and detects the rotation angle α of the rotation shaft 12 from the reference position P (the angle measured in the positive direction is +). It has become. That is, when the turning arm 5 is turned in the positive (right) direction in FIG. 2 by the turning torque of the torque motor 13, the turning angle of the turning arm 5 (turning of the turning shaft 12) is detected from the photosensor 15. The number of detection pulses based on the motion angle) is output. Further, even when the rotating arm 5 is rotated in the reverse (left) direction in FIG. 2 against the rotating torque of the torque motor 13, the photo sensor 15
Outputs a number of detection pulses based on the rotation angle of the rotation arm 5 (rotation angle of the rotation shaft 12). The CPU 20 detects the turning angle of the turning shaft 12 (that is, the turning angle of the turning arm 5) α according to the number of detection pulses output from the photo sensor 15.

Further, the CPU 20 has a timer function. Then, the CPU 20 resets the timer when the rotation angle α does not change for a certain time or longer, and the rotation angle α
Is started, the timer operation is started and the time t from when the rotation angle α starts to change is measured. When the time t reaches the predetermined value Δt, the CPU 20
A change amount Δα of the rotation angle α with respect to the predetermined value Δt is calculated.

On the other hand, C is provided on the output side of the CPU 20, respectively.
The CRT 3, the torque motor 13, and the speaker 4 are connected via the RT drive circuit 23, the motor drive circuit 24, and the speaker drive circuit 25.

Then, based on the control program stored in the ROM 21, the CPU 20 determines the torque when the change amount Δα of the rotation angle α becomes equal to or more than a predetermined value when the time t reaches the predetermined value Δt. The rotation torque of the motor 13 is reduced to a predetermined value. That is, CPU2
0 is the rotation angular velocity ω (= Δα / of the rotation shaft 12 of the rotation arm 5).
When Δt) becomes a predetermined value k or more, the torque motor 13
The rotation torque of is reduced to a predetermined value.

That is, the case where the rotational angular velocity ω of the rotating arm 5 becomes equal to or more than the predetermined value k is when the player suddenly applies a large force to the rotating arm 5. At this time, the rotating arm 5
If the turning torque is reduced, the reaction of the force applied by the player to the turning arm 5 becomes smaller. Therefore, no excessive force is applied to the bones of the player, and even if the player suddenly applies a large force to the rotating arm 5, the throwing bone fracture does not occur. The rotation angular velocity ω and the predetermined value k are previously obtained by experiments.

Further, the CPU 20 uses the control program stored in the ROM 21 to explain the rules and the CRT.
The speaker 4 outputs the profile of the opponent displayed in 3 and cheers and angry voices during the battle.

In the present embodiment, the sensor plate 1
4, the photo sensor 15 and the CPU 20 constitute a speed detecting means. Next, the actual game and the operation of the CPU 20 according to the present embodiment configured as described above will be described with reference to FIG.

First, when a player inserts a coin and turns on the start switch 9 (step [hereinafter referred to as S] 1), the CPU 20 reads the display data of the initial screen display from the ROM 21 and displays it on the CRT 3. Let (S
2). Here, an explanation of how to use the game machine and rules is displayed on the initial screen of the CRT 3. In the explanation of the rule, it is dangerous that a player suddenly applies a large force to the rotating arm 5 because a phenomenon called throwing bone fracture occurs. Therefore, a large force is rapidly applied to the rotating arm 5. It is a violation of the rules to add, in which case the game will be restarted from the beginning, etc.

When any one of the selection switches 10 is pressed (S3), the CPU 20 reads out the display data of the opponent stored in the ROM 21 and displays the opponent on the CRT 3. Then, the CPU 20
Similarly, the voice data relating to the profile of the opponent stored in the ROM 21 is read out, and the profile of the opponent is introduced through the speaker 4 (S4).

Here, the player holds the grip 1 with the left hand and holds the palm of the rotary arm 5 with the right elbow attached to the elbow rest 7 on the support base 6 to adjust the posture. CPU20
Waits for the motor start signal to be output from the pressure sensor 16 (S5). When the motor start signal is output from the pressure sensor 16, the CPU 20 reads the torque data set for the opponent from the ROM 21, and sets the torque motor 13 to a predetermined turning torque (set torque) based on the torque data. The rotation arm 5 is rotated to apply a set torque to the rotation arm 5 (S6).

Subsequently, the CPU 20, based on the control program stored in the ROM 21, when the time t reaches a predetermined value Δt (for example, 0.1 seconds), the rotation angle α.
Whether or not the amount of change Δα of the rotation arm 5 is equal to or greater than a predetermined value (for example, 30 °), that is, the rotation angular velocity ω (= Δα / Δt) of the rotation arm 5 (rotation shaft 12) is equal to a predetermined value k (for example, Thirty
0 ° / sec) or more is determined (S
7). When the rotation angular velocity ω of the rotation arm 5 is equal to or larger than the predetermined value k, the CPU 20 reduces the rotation torque of the torque motor 13 to a predetermined value (for example, 30% of the set torque) (S8). As a result, the turning torque of the turning arm 51 is reduced, so that the player's throwing bone fracture can be prevented. Next, the CPU 20 is dangerous because a phenomenon called throwing bone fracture occurs when such a large force is suddenly applied to the rotating arm 5, and therefore a large force is rapidly applied to the rotating arm 5. It is a rule violation to add it, and the CRT warns that the game will start over from the beginning.
3 is displayed (S9). Then, the process returns to S5.

On the other hand, when the rotational angular velocity ω of the rotary arm 5 is less than the predetermined value k, the CPU 20 determines whether the rotational angle α is increased, that is, whether the opponent is dominant. Yes (S10). Then, when the CPU 20 determines that the rotation angle α is + 80 ° (S11), the player loses the game (S13) and ends the game. If the player is superior, the CPU 20 determines that the rotation angle α is −80 ° (S12), performs the player winning process (S14), and selects one of the selection switches 10. Wait for another opponent to be selected.

Thus, in this embodiment, the CPU 20
Resets the timer when the rotary shaft 12 of the rotary arm 5 does not change for a certain time or more, and starts the timer operation when the rotary angle α starts to change, and the time t after the rotary angle α starts to change. measure. Further, the CPU 20 determines that the time t is the predetermined value Δ.
When it reaches t, the change amount Δα of the rotation angle α with respect to the predetermined value Δt is calculated to obtain the rotation angular velocity ω (= Δα / Δt) of the rotation shaft 12 of the rotation arm 5. Then, the CPU 20
When the rotation angular velocity ω of the rotation arm 5 becomes a predetermined value k or more,
It is determined that the player suddenly applies a large force to the rotating arm 5, and the rotating torque of the rotating arm 5 is reduced to a predetermined value.

Therefore, in this embodiment, it is possible to prevent the player's throwing fracture. Further, even when the player applies a strong force to the rotating arm 5, if it is a slow one without the risk of throwing bone fracture, the rotating torque in the positive direction given to the rotating arm 5 is It will be added along with the normal program. Therefore, the player can fully enjoy the arm-wrestling game.

The present invention is not limited to the above embodiment, but may be implemented as follows, for example. 1) The rotation angular velocity ω of the rotation shaft 12 of the rotation arm 5 is detected using a speed sensor.

2) Instead of detecting the rotational angular velocity ω from the rotational angle α of the rotational shaft 12, the rotational angular velocity ω is detected from the rotational angle of the rotary arm 5. 3) Instead of judging that the player suddenly applied a large force to the rotating arm 5 based on only the rotational angular velocity ω of the rotating arm 5, the player applies the force to the rotating arm 5. In addition, the risk of the rotational angular velocity ω when the reverse rotational torque is equal to or greater than a certain value is calculated and processed.

That is, as described above, the case where the turning torque in the reverse direction applied to the turning arm 5 by the player is a certain value or more, and the turning angular velocity ω is a certain value or more, 2
When the two conditions () are satisfied, the throwing bone fracture occurs. Therefore, when these two conditions () are satisfied, the turning torque damping process described above is performed. Specifically, the following method may be used.

The torque sensor provided on the turning arm 5 directly detects the turning torque of the turning arm 5, and the player turns the turning arm 5
The rotational torque in the reverse direction applied to is detected. The rotational angular acceleration of the rotary arm 5 is detected by the acceleration sensor provided in the rotary arm 5, and the reverse rotational torque applied to the rotary arm 5 by the player is detected based on the rotational angular acceleration. To do.

4) Instead of causing the CPU 20 to perform the timer operation, a timer controller is provided as a peripheral circuit,
The timer controller is caused to perform the timer operation.
