DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in FIG. Reference numeral 1 denotes a base, which constitutes a case 2. Reference numeral 3 denotes a column fixed on a base, and supports a swing table 5 at its upper end via a joint 4. As shown in FIGS. 4 and 5, the joint 4 includes first bearings 41, 41 at the upper end of the column 3.
In addition, both ends of the first support shaft 42 are rotatably supported by an axis along the rolling axis A. 43 is the first
A movable block integrated with the support shaft 42, and a second support shaft 44 having an axial line orthogonal to the first support shaft 42 on the same plane on both sides thereof is provided. Reference numerals 45, 45 denote second bearings mounted on the lower surface of the swing table 5, which rotatably support both ends of the second support shaft 44.

Reference numeral 6 denotes a first angle detector, for example, a resolver. The rotor is attached to the shaft end of the first support shaft 42, and the outer frame is attached to the fixed part of the support 3 by the support spring 7. Reference numeral 8 denotes a second angle detector, in which the rotor is attached to the second support shaft 44 and the outer frame is attached to the swing table 5 via the support spring 9. A cockpit 10 is formed on the rocking table 5, and a CRT 11 is provided on the front surface, and an operation panel 12 and an operation handle 13 are provided.
A seat 15 is provided together with the speaker 14 and the like.

[0008] Reference numerals 20 and 30 denote servomotors fixedly provided in the case 2 of the base 1. Reference numerals 21 and 31 denote brakes connected to the servomotors 20 and 30, respectively (in the embodiment, integrated with the servomotors). When the power of the servomotor is turned off and the device is in a non-excited state, the device holds the rotating shaft by braking. Reference numerals 22 and 32 denote reduction gears connected to the rotation shafts of the servomotors. Crank arms 24 and 34 are fixed to output shafts 23 and 33, and one ends of operation rods 25 and 35 are connected to the crank arms. Is connected to the swing table 5 via free joints 26 and 36, respectively.

Next, the operation will be described. When the player sits on the seat 15 and turns on the power switch, the CRT
The screen is projected, and the player operates the control panel 1 according to the screen.
2 and the operation handle 13 are operated.

When the player operates the operating handle 13 to the right and tilts the rocking table 5 to the right, a command is given to a control circuit (not shown) by the movement of the operating handle, and the braking of the brake devices 21 and 31 is performed. As well as being released, the operation direction and operation amount (operation angle) of the operation handle 13
For example, the output voltage of the volume resistor that rotates in relation to the handle shaft changes in response to
Rotation amounts corresponding to the respective rotation directions and output voltage values are commanded to 0 and 30 to drive in the direction indicated by arrow C in FIG. For this reason, the crank arms 24 and 34 rotate by an angle corresponding to the handle operation amount via the speed reduction devices 22 and 32, thereby raising the operation rod 25 and lowering the operation rod 35. Therefore, the swinging table 5 rotates the first support shaft 42 of the joint 4 to the right around the rolling axis A, and performs a rolling operation as shown by a chain line in FIG. First angle detector 6 mounted
Detects the rotation angle, and feeds back the detected value to the control circuit to perform rolling by the command amount by the steering wheel.

When the operating handle 13 is operated to tilt the rocking table 5 to the left, the input to the control circuit is switched, and the servomotors 20, 30 are driven in the direction of arrow D.
The first support shaft 42 rotates to rotate the swing table 5 in the leftward tilt direction, and the detection value of the first angle detector 6 is fed back to the control circuit. At the time of this rolling operation, the second support shaft 44 and the second bearings 45, 45 are tilted integrally with the swing table 5 and do not rotate, and the first support shaft 42 is moved within the first bearings 41, 41. It rotates and does not rattle due to the bearing accuracy on both sides.

Next, when the operation handle 13 is pushed forward to tilt the swing table 5 forward, the direction and the operation angle are commanded to the control circuit by the movement of the handle shaft, and the servo motor 20 is moved in the C direction. The servo motor 30 is driven in the D direction, the operating rods 25 and 35 are both pushed up, and the swing table 5 is tilted forward about the axis of the second support shaft 44 to perform the pitching operation. At this time, the second support shaft 44
Does not rotate because the movable block 43 and the first support shaft 42 are supported by the first bearings 41, 41, and the second bearing 4
Only 5 and 45 rotate together with the swing table 5, and the detection value is fed back from the second angle detector 8 to control the rotation amount of the servo motor.

When the operating handle 13 is pulled down and the swing base 5 is tilted backward, the servo motor 2
0 is driven in the D direction, the servo motor 30 is driven in the C direction, the operating rods 25 and 35 are both pulled down, and the rocking table 5 performs a pitching operation in which the rocking table 5 tilts backward about the second support shaft 44, The inclination amount is detected by the second angle detector 8.

It is natural that the rolling and pitching operations can be performed in combination, and the rocking table is automatically operated by issuing a command from the control circuit in accordance with the CRT screen without operating the operation handle. Alternatively, the first bearing may be supported on the rocking table side, and the second bearing may be supported on the column side. Further, when a power-off command is issued to the control circuit due to the end of the game, the excitation of the servomotor is held until the detection values of the first and second angle detectors become initial values, and the rocking table is rolled. After returning to the center position of the pitching, the brake device is operated, and the rocking table is stopped in a horizontal state.

[0015]

As described above, according to the present invention, the first and second support shafts are disposed at the upper end of the column provided with the rocking base on the base and arranged with the rolling axis and the axis perpendicular to the rolling axis. By supporting the rocking table, the rocking table can be stably held without play by fitting the support shaft and the bearing, thereby eliminating rattling.

[0016] Further, by supporting the rocking table by a shaft, the load of the rocking table is received by a joint, and the connection between the rocking table and the base is changed to a hydraulic cylinder by an operation rod having low mechanical strength. By using a servo motor fixed to the base and braked at the time of non-excitation and a reduction gear, the output shaft of the reduction gear and the rocking table can be connected by an operation rod via a crank. For this reason, the rolling and pitching operations of the rocking table can be performed by electric operation instead of hydraulic pressure, thereby reducing the control time lag and improving the responsiveness of the operation according to the movement of the CRT screen. In addition to increasing the sense of unity with the game, it enhances the game feeling, and also ensures that the output shaft can be securely braked during non-excitation or power outages to maintain safety.The drive device such as a servomotor is fixed on the base. The installation is simple and the structure is simple,
Maintenance is easy because there is no need to manage the amount of oil or oil leaks.

Further, by attaching an angle detector to the first support shaft and the second support shaft, the tilt amount of the rocking table can be detected and the operation amount can be reliably controlled.
