A gaming machine includes a light emitting portion, a terminal controller, a light emission control unit, a power supply unit, an input device through which a predetermined input is externally input, and a light emission power control unit. Systems and methods provided herein further include a sum-delta processor configured to utilize the RSSI values to generate an off-bore-sight angle of the antenna array relative to a position of a transmitting radiofrequency signal source. Moreover, a luminance distribution of the processing image is leveled. The processor is programmable in response to signals received through the output cable so as to re-configure the program thereof so as to change the output to the output cable for different end use controllers and for compatibility with communications protocols. When the stop button MB1 is pressed, the slide member 10 receives force F2 at a stop input part 12 and slides in the direction indicated by an arrow A1.
