  • Patent number: 7431651
    Abstract: A data processing method is provided whereby, even if communication delay occurs between computer game devices connected through a communication network, data is processed practically simultaneously between the respective computer game devices. When a computer game contest is carried out through a network having communication delay, before the game is started, the delay times between the game devices are found and, using these, synchronization of the time counted by the individual game devices is obtained. Then, during the progress of the game, the operating data signal is processed after the lapse of the longest delay time of the delay times between the game devices measured beforehand after it is generated. In this way, the operating data signal can be processed simultaneously in a plurality of game devices.

  • Patent number: 6164646
    Abstract: To provide a ball game machine which can prevent unevenness of the drawing result by improving a way of allotting property to each of the ball holding portions provided on a wheel device, the ball game machine includes: a wheel device rotatable along a circumferential direction thereof and provided with a plurality of ball holding portions along the circumferential direction; and a feeding device for feeding a ball toward the wheel device; a property setting device for setting a property to each of the ball holding portions in such a manner that the property set to at least one of the ball holding portions is distinguishable from the property set to another one of the ball holding portions. The property setting device is capable of changing a setting state of the property. The game machine further includes a drawing result issuing device for issuing a drawing result signal corresponding to the property set to one of the ball holding portions in which the ball is introduced.
