A direction detection device is provided for a game machine combined exercise bike. The direction detection device include a detection module mounted to a direction rotation module composed of a rotatable portion and a fixed portion. The detection module includes a plurality of signal receiver elements and a signal transmitter element, which are operated in a non-contact manner and are allowed for relative rotation with respect to each other. Each signal receiver element has a range of detection. During relative rotation between the signal transmitter element and the signal receiver elements, when the signal transmitter element is moved into the detection range of one of the signal receiver elements, the signal receiver elements detect a positional message of the signal transmitter element, and the signal receiver elements applies the message to a signal processing device of the game machine, which converts the positional message into a direction signal.
