  • Patent number: 10115262
    Abstract: A rotating apparatus for a game system having a light-emitting device includes a rotating member that rotates on a fixing member, light-irradiated areas that are partitioned and formed in a circumferential direction of the rotating member, light sources annularly arranged in the fixing member that irradiate the light-irradiated areas with light, a light-blocking body that is formed in the rotating member so as to prevent the light, with which a specific light-irradiated area as a light irradiation target out of the light-irradiated areas is irradiated, from leaking into other light-irradiated areas and adjacent to the specific light-irradiated area, and a control unit that controls a timing of changing light intensity of the light sources, and the control unit turning on and off the light sources in synchronization with the rotation of the specific light-irradiated area as the light irradiation target.

  • Patent number: 10035062
    Abstract: A roulette lottery apparatus with a novel configuration causes a player not to lose interest. The roulette lottery apparatus 1 for a roulette game comprises: plural roulette bodies that have plural ball pockets into which lottery balls enter, the plurality of roulette bodies being held so as to be rotatable about a horizontal or tilted rotation axis in a state where a rotation plane of the ball pockets is raisable, each of the plurality of the roulette bodies having different diameters; a drive source that rotationally drives the roulette bodies; and ball guide members that guide the balls to enter into any ball pocket among the ball pockets while causing the balls to be in pendular movement. The plural roulette bodies are arranged in a stepped state in which the roulette bodies are displaced in an axis direction on the rotation center line.

  • Patent number: 7313385
    Abstract: When gateway server 30 receives an email, which is addressed to mobile station 10, gateway server 30 transmits an email arrival notice to mobile station 10. When gateway server 30 receives an acknowledgement response (referred to as ‘Ack’ hereinafter) responding to the email arrival notice from mobile packet communication network 20, gateway server 30 evaluates the status of mobile station 10 on the basis of the type of Ack, and determines whether to transmit the email or not. Moreover, gateway server 30 modifies the time interval for retransmitting the email arrival notice to mobile station 10 according to the status of mobile station 10 when the transmission of the email arrival notice fails.

  • Patent number: 6514145
    Abstract: A height adjustable game machine having a structure that can be easily adapted to a stand-up-type and a sit-down-type depending on situations. Each of a game controller, a game operation panel and a monitor is set as a unit. A base unit 2 accommodating the controller 3, the game operation unit 5 and the monitor unit 9 are held between opposed columns 4 in this order from the bottom. As a result, the height of the machine can be altered merely by changing the length of the columns 4, and it is possible to structure the game machine as a stand-up-type for a standing player or a sit-down-type for a seated player.
