Patent number: 9787233Abstract: A movable body drive device that controls a drive unit configured to drive a movable body arranged on a game machine has a communication unit that receives a control command for regulating a destination position of the movable body, a storage unit that stores a current position of the movable body, and a control unit that determines, based on a difference between the destination position and the current position or a moving direction in an immediately previous action of the movable body, a moving direction in the next action of the movable body and to control the drive unit such that the movable body is moved along the moving direction in the next action until the movable body reaches the destination position.Type: GrantFiled: June 22, 2012Date of Patent: October 10, 2017Assignee: OMRON CorporationInventors: Norihisa Takahashi, Katsumi Matsushita, Yasuyuki Ohba, Hiroyuki Ibuki

Patent number: 9672683Abstract: A drive control system has: a plurality of drive control devices; and an upper-level control device to which each of the drive control devices is connected in parallel with each other via a common signal line. The upper-level control device transmits a common information acquirement request signal to each of the drive control devices. Upon receiving the information acquirement request signal, each of the drive control devices determines transmission start timing for a response signal based on transmission sequence information indicating its transmission sequence and a length of the response signal such that the response signal does not temporally overlap with a response signal being transmitted from another drive control device to the upper-level control device. Each of the drive control devices transmits the response signal to the upper-level control device via the signal line at its transmission starting timing.Type: GrantFiled: May 23, 2014Date of Patent: June 6, 2017Assignee: OMRON CORPORATIONInventors: Katsumi Matsushita, Hiroyuki Ibuki, Yasuyuki Ohba

Patent number: 9266016Abstract: A game machine has a game machine main body, a plurality of light sources arranged on the game machine main body, a light source control device that controls the plurality of light sources, and a rendition control unit that controls a rendition depending on a state of a game. Each of the plurality of light sources has an anode connected to any one of a plurality of first signal lines, a cathode connected to any one of a plurality of second signal lines, and a different combination of the connected first signal lines and the connected second signal lines.Type: GrantFiled: June 22, 2012Date of Patent: February 23, 2016Assignee: OMRON CorporationInventors: Katsumi Matsushita, Yasuyuki Ohba, Norihisa Takahashi, Hiroyuki Ibuki

Patent number: 9143069Abstract: A drive control device having: a storage circuit configured to store a reference rotational speed table; a drive signal generation circuit configured to output a drive signal to the direct current motor; and a control circuit. When an absolute value of a difference between a second rotational speed corresponding to a first rotational direction and a third rotational speed corresponding to a second rotational direction is equal to or larger than a predetermined threshold, the control circuit creates separate rotational speed tables for the first rotational direction and the second rotational direction in which each rotational speed table indicates a relation between a rotational speed and an electric power amount per unit time, and determines an amount of electric power that is supplied to the direct current motor which corresponds to a designated rotational speed according to the rotational speed table selected in accordance with a designated rotational rotation.Type: GrantFiled: May 23, 2014Date of Patent: September 22, 2015Assignee: OMRON CorporationInventors: Katsumi Matsushita, Hiroyuki Ibuki, Yasuyuki Ohba
