MODE FOR THE INVENTION

As illustrated in FIGS. 2 and 3, a game controller having a control wheel includes a main body 100 and a control wheel 200 which is mounted on the main body 100 or an upper part of the main body 100 and rotated by the control of a user.

The control wheel 200, as illustrated in FIG. 3, is mounted on the main body 100 so that it can be rotated by using a user's fingers.

Although the control wheel can be controlled by using any part of a human body, it will be most convenient to use thumbs to control the control wheel and use the remaining fingers to take hold of the game controller as illustrated in FIG. 3.

The control wheel 200 includes a wheel rotation unit 210, a rotation detection unit 220, a rotation load unit 230 and a circuit block 240.

The wheel rotation unit 210, which is in contact with the user's fingers, is mounted on the main body 100 or the upper part of the main body 100 of the game controller so that it can rotate.

The rotation detection unit 220 detects a rotation angle and a rotation direction of the wheel rotation unit 210.

The rotation load unit 230 controls a rotation load on the wheel rotation unit 210 according to circumstances of a game so that the user can feel like the user is driving in an actual race.

The circuit block 240 receives data from the rotation detection unit 220 to apply the data to the game and controls the rotation load, which is provided from a racing program, in the rotation load unit 230.

In detail, the wheel rotation unit 210 includes a wheel plate 211 which is disposed or mounted on the upper part of the main body 100 of the game controller to be rotatable and rotatable disks 212 which are disposed on the right side and the left side of the upper part of the wheel plate 211. For the wheel rotation unit 210, a plate structure which can rotate around a center axis, such as a disk, can be mainly used.

At the upper part of the wheel plate 211, receptible grooves 211 a are formed to place each of the rotatable disks 212.

Each of the rotatable disks 212 is combined to the wheel plate 211 with screws 213. As shown in FIG. 3, the user puts thumbs on the wheel rotation unit 210, especially on the rotatable disks 212, and gives a turning force to them so that the wheel plate 211 can rotate around the center axis of the wheel plate 211.

The rotatable disks 212 can be combined to the wheel plate 211 to be rotatable. In this case, the rotatable disks 212 rotate separately when the wheel plate 211 rotates so that it is possible to prevent thumbs on the rotatable disks from being pushed through a contact with the wheel plate 211. Thus, the user can rotate the wheel plate more easily and conveniently.

The rotation detection unit 220 includes a detection plate 221 which is connected to the wheel rotation unit 210, more precisely, to the wheel plate 211 in the same axis and has a plurality of holes formed on its circumference around the same axis and a sensor 222 which detects a rotation angle and/or a rotation direction of the detection plate 221 and transmits data to the circuit block 240.

It is desirable for the sensor to have a structure capable of detecting the rotation angle and rotation direction of the detection plate 221 by detecting positions of the holes formed on the detection plate 221 and a change of speed when the detection plate 221 is rotated.

For example, as illustrated in FIG. 2, the sensor 222 includes a light emitting unit and a light receiving unit and has a structure that the plurality of holes formed on the detection plate 221 pass between the light emitting unit and the light receiving unit. That is, the light emitting unit and the light receiving unit cover an edge of the detection plate 221 having the plurality of holes. In general, the light emitting unit includes a light emitting diode (LED) and the light receiving unit includes a light sensor for sensing light emitted from the LED.

The sensor 222 detects the rotation angle and rotation direction of the detection plate 221 and the wheel rotation unit 210 by sensing the movement of the holes formed on the detection plate 221.

The rotation load unit 230 includes a gear unit which is engaged to the center axis of the wheel rotation unit 210 and a motor 235 which is combined to the gear unit.

It is desirable for the gear unit to have a plurality of gears which are combined to the center axis of the wheel rotation unit 210, more precisely, the wheel plate 211. For example, as illustrated in FIG. 2, the gear unit can include a first gear 231, a second gear 232 which is engaged to the first gear 231 and a third gear 233 which is engaged to the second gear 232 and the motor 235.

At this time, the diameter of the second gear 232 is made bigger than that of the first gear 231 to reduce a rotation speed of the wheel rotation unit 210.

The circuit block 240 includes a rotation signal transmission unit and a load control unit.

The rotation signal transmission unit of the circuit block 240 receives a rotation signal detected by the sensor 222, changes the signal into digital data and transmits the data to an input unit of the game controller. The game controller reflects the received data in a direction change or a rotation of a moving object which races.

The load control unit of the circuit block 240 receives a data signal indicative of a game progress, namely, a speed or rotation of the moving object which races in order to generate a motor control signal and transmits the signal so that the motor 235 is loaded or unloaded, rotated or reversely rotated. Accordingly, the motor 235 controls the load on the gear unit and the wheel rotation unit 210 in order that the user can feel like he is actually steering a wheel in various driving situations. That is, the user can rotate the rotatable disks lightly when the motor is unloaded, and the user can actually feel a rotation load in rotating the rotatable disks when the rotatable disks are loaded during a racing (a rotation in the low speed or a rapid rotation) because an electrical signal is given to the motor to increase the rotation load.

The operational state and process of the present invention are as follows.

When the user plays a racing game, he puts thumbs on the rotatable disks 212 and rotates the wheel plate 211 to the left or to the right according to game circumstances.

When the wheel plate 211 rotates, the detection plate 221 also rotates. At this time, the sensor 222 detects the rotation angle and rotation direction of the detection plate 221.

The derived data are transmitted to the circuit block 240 and transmitted again to the input unit of the game controller so that the moving object which races in the game moves.

Meanwhile, in case that the rotatable disks are to be loaded considering the speed or rotation of the moving object which races in the game, the circuit block 240 rotates or reversely rotates the motor 235 and the rotating power of the motor 235 is transferred to the wheel plate 211 by way of the gear unit. Thus, the user can control the strength and weakness of the load when rotating the wheel rotation unit 210.

Therefore, the user can enjoy the racing game rich in reality.

The rotatable disks of the present invention are not merely used as driving means in the racing game. They can also perform the function of moving a cursor like buttons and joysticks when watching other games or reading material.
