Gazette).

[0003]

However, in the sensation-type game machine proposed in the prior art, the apparatus is very expensive because it swings using a servomotor. In addition, since the rocking table is supported by spherical bearings, if it is rocked in one direction, it will be tilted in the direction perpendicular to it, and there is a problem that basically only one axis operation is possible. Was.

[0006]

Embodiments of the present invention will be described below. 1 is a view showing the overall configuration of the game machine of the present invention, FIG. 2 is a cross-sectional view taken along the line C--C of FIG. 1, FIG. 3 is a cross-sectional view taken along the lines A--A and BB of FIG. 1, and FIG. It is a figure which shows the cross-shaped universal joint which is. The swing table 1 on which the seat 7 on which the game player sits is mounted is supported on the base 4 by a cruciform universal joint 5 serving as a swing table receiver, and the base 4 and the swing table 1 have a skirt made of bellows. 6 is covered. As shown in FIG. 4, the cross-shaped universal joint 5 is configured such that the rotation axis in the X
The rotation shafts in the Y direction penetrate and can rotate around each other.

[0007] The swing table 1 is driven by two three-phase AC motors 2 and 3. The three-phase AC motor 2 is a reduction gear 2a
To rotate the connection rod 2d connected to the crank arm 2c and to the swing table 1 by the universal joint.
The connection rod 2d is Y─Y of the cross-shaped universal joint 5.
X─X of the cross-shaped universal joint 5 on the center line of the rotating shaft
At a position separated from the center line of the rotating shaft by a predetermined distance. The three-phase AC motor 3 is a reduction gear 3a
To drive the connection rod 3d connected to the crank arm 3c and connected to the swing base 1 by the universal joint.
The connection rod 3d is the X-X of the cross-shaped universal joint 5.
Of the cross-shaped universal joint 5 on the center line of the rotating shaft in the direction
At a position separated from the center line of the rotating shaft by a predetermined distance. As described above, since the action point of the X-axis swing and the action point of the Y-axis swing are respectively on the center lines of the respective rotary shafts of the cross-shaped universal joint 5, the swings in the X and Y directions interfere with each other. Therefore, two-axis operation can be performed.

The rotation angles of the cranks of the three-phase AC motors are detected by rotary encoders 2e and 3e connected to the motor shafts, respectively, and are rotated by rotating plates 2b and 3b provided on the opposite side of the crank arm. The top dead center, middle point, and bottom dead center are respectively detected by the proximity sensor. Each of the speed reducers 2a and 3a uses a worm gear. The worm is rotated by a motor shaft, and the crank arm is rotated by a worm wheel that rotates in mesh with the worm. Although the worm gear has reduced rotation transmission efficiency, a large force is required to rotate the worm from the crank side via the worm wheel. Therefore, it is desirable to use a motor with a brake, but the motor can be used even if the brake is omitted.

In front of the seat 7, two safety bars 10 are provided on both sides, and are set at a set position and a reset position by a solenoid so that a player does not leave the seat. At the tip of the safety bar 10, a handle 11 to be gripped by the player is provided. The handle 11 is made of a foamed conductive sheet, as will be described later. The player is tensed by swinging, and when the grip force changes, the resistance value changes, and the player's degree of tension is measured.

[0010] The video of the game is displayed on the monitor 8 together with the sound, and the player can view the screen on the rocking table 1 which rocks in synchronization with the video or sound while enjoying the sense of reality due to the rocking. . Reference numeral 9 denotes an exterior of the monitor.

Next, the configuration of the control device according to the present invention will be described.

The processing unit 23 captures signals from the motion sequencer 24 which generates a sequence operation signal in synchronization with a synchronization signal SYNC with video or sound obtained through the command processing unit 23, sensors, switches, and encoders installed in the game machine. Switch control unit 2
5. The motion sequencer 26 includes a motion control unit 26 that receives signals from the motion sequencer and the switch control unit and outputs a drive control signal for the rocking table.

The system section 21 sends video and audio data constituting the game to the video circuit 29 and the audio circuit 30, and the video is displayed on the monitor 8. Further, the player's face is photographed by the camera 31, and the situation of the player is taken into the system section 21 and monitored. The content of the command issued from the system section is

Data transfer for moving the rocking table, data transfer requests from sensors and switches for grasping the state of the rocking table, and the like.

The switch control unit 25 includes a command processing unit 23
The data from the sensors, switches, and encoders are fetched in accordance with the instruction from, and are transferred to the system unit 21 via the command processing unit 23. Motion sequence 2
When a game is executed, a command is transmitted to the motion control unit 26 in synchronization with a synchronization signal SYNC synchronized with a video signal from the system unit to control the elevation of the X and Y axes of the rocking table. The information of the motion control in this case is a motion list (Standard MIDI File: SMF).
Is stored as a MIDI control change message together with the time information of the occurrence timing.

MIDI is an international standard established as a control format for electronic musical instruments, and data is exchanged using messages of a plurality of bytes. This message consists of a status byte and one or two bytes of data, depending on the status, unless otherwise specified. The message is composed of a channel message designating channels 1 to 16 and a system message which is information necessary in common for the connected devices of the entire system. The channel message is a voice (pronunciation) of the device (receiving side). And a mode message that determines how the receiving device processes the voice message. In the present invention, a control change message (a group of messages that triggers an extension or the like for sounding)

Also, as shown in FIG. 8, A and B pulses having phases different by 90 ° are generated from the encoders 2e and 3e attached to the rotating shaft of the motor, and the crank of the crank is determined by the phase relationship between the A and B pulses. By detecting the rotation direction and counting the number of pulses, the rotation angle is recognized with high resolution (encoder resolution × gear ratio).

The signal from the motion control unit 26 is output as a voltage signal, and the inverters 27 and 28 change the output frequency according to the input voltage value to accelerate and decelerate the three-phase AC motors 2 and 3. The rocking plate 1 is rocked to increase the show effect.

The grip strength is detected by detecting the resistance value, and the player's tension is measured. In the present invention, MI
Although the rocking board is controlled by the DI signal, it is also possible to detect the degree of tension and feed it back to use the rocking board for control. In addition, this handle can detect a human grip force by a change in resistance value, and thus can be used as a grip force meter.

[0022]

As described above, according to the present invention, inexpensive 3
The swing table is driven by decelerating with a worm gear using a phase AC motor. At this time, the swing table supported by the cruciform universal joint is moved in the X and Y directions at the action point on the center line in the X and Y directions. Since the swinging is performed in the directions, the swinging of the X-axis and the Y-axis does not interfere with each other, so that the two-axis operation can be performed completely.
