Patent ID: 8471680

Claim:
A system comprising: a turntable for a display unit, comprising: a mounting section that is mounted with a display unit, and an electric rotating mechanism that rotates said mounting section, wherein rotation by said electric rotating mechanism has a limit in each of forward and backward rotation around a horizontal axis, and a limit in each of clockwise and counter-clockwise rotation around a vertical axis; a remote control unit that transmits a wireless signal; a reception section that is installed in said mounting section or said display unit, and receives a wireless signal from said remote control unit; and a control section that controls said electric rotating mechanism based upon said wireless signal received in said reception section, wherein, upon receipt of a wireless signal from said remote control unit in said reception section, said control section performs: an initial operation in which said control section detects a reception strength of said wireless signal in said reception section while cyclically rotating said mounting section about a predetermined range defined in terms of boundaries of forward/backward rotation around the horizontal axis and clockwise/counterclockwise rotation around the vertical axis, said boundaries being within the rotation limits of said electric rotating mechanism, around a predetermined rotational position through said electric rotating mechanism, to determine a first rotational position at which said reception strength is maximum among the detected results of the initial operation, wherein the rotation of the mounting section during the initial operation is not dependent on detection of the reception strength, and a main operation in which said control section returns the rotational position of said mounting section to said first rotational position, further rotates said mounting section from said first rotational position in a main rotation direction extending from said predetermined rotational position to said first rotational position until the rotational position of said mounting section reaches either the forward/backward limit or the clockwise/counter-clockwise limit while detecting the reception strength of said wireless signal in said reception section, wherein after the rotational position of said mounting section is returned to said first rotational position, the direction of rotation of said mounting section during the main operation is limited to the main rotation direction, determines a second rotational position at which said reception strength is maximum among the detected results of the main operation, and rotates said mounting section to the second rotational position.
