Abstract
The present invention provides an entertainment system in which the models can be discriminated between compatible operation devices. A connector of the operation device of the present invention comprises at least two recess portions on the peripheral surface thereof, and a connecting portion of a machine body is provided with at least two metal projections arranged thereon to be engaged with the respective recesses. The connector includes a metal plate, and the metal plate is exposed inside of the first recess and the second recess. A supplying portion of the machine body supplies a predetermined potential to the metal plate by supplying the predetermined potential to the first metal projection engaged with the first recess. A detecting portion of the machine body determines whether the connected operation device is the operation device or not by detecting a potential of the second metal projection engaged with the second recess.
