Abstract
This invention concerns an external operation device and makes it possible to conduct communication at a faster rate than previously. The operation means is connected to the operation object via an optical fiber and by converting the electrical signals of the transmission object to optical signals during communication and transmitting said optical signals via optical fibers, even if the frequency is high, no electromagnetic-wave noise is generated as happens when the operation means is connected to the operation object via electrically conductive wires. Thus there is no need to limit the frequency of the optical signals, that is, the communication speed, and therefore communication can be done at a faster rate than previously.
Claims11
An external operation device connected to an operation object and by which the operation object is operated said external operation device comprising:
- an operation means that converts electrical signals of a transmission object, generated in accordance with operation by a user input, to optical signals by an internal electro-optical signal converter and outputs said optical signals to said operation object, and converts received optical signals transmitted from said operation object to electrical signals by said electro-optical signal converter and outputs information in accordance with said converted electrical signals,
- an optical fiber, one end of which is attached to said operation means, that transmits optical signals between said operation means and said operation object,
- electrical conductive wire for transmitting electrical signals, and having one end of which is attached to said operation means, and
- a connection means provided on an other end of said optical fiber and said electrical conductive wire, said connection means is detachably connected to said operation object and converts optical signals transmitted from said operation means via said optical fiber to electrical signals by an internal electro-optical signal converter and outputs said electrical signals to said operation object, and converts electrical signals supplied from said operation object to optical signals by said electro-optical signal converter and outputs said optical signals to said operation means via said optical fiber, and couples said electrical conductive wire to said operation object,
- wherein said external operation device sends operation information input by a user to said operation object, and said external operation device informing the user by receiving feedback information from said operation object, and
- wherein said operation object is a game machine.
An entertainment system comprising:
- a game machine main unit,
- a user interface game controller, and
- cable data transmission means between said game machine main unit and said user interface game controller, said cable data transmission means including
- an optical cable,
- an electrically conductive cable,
- a connector provided on an end of said optical fiber and said electrical conductive wire, said connector is detachably connected to at least one of said game machine main unit and said user interface game controller,
- wherein signals that can be a source of electromagnetic-wave noise are transmitted via said optical cable and signals that cannot be a source of electromagnetic-wave noise are transmitted via said electrically conductive cable.
