As the mouse device is swung in a leftward direction or a rightward direction, the front side and the rear side of the mouse device are simultaneously tilted. Moreover, since the first pressing part or the second pressing part of the first swinging element is pushed by a working surface where the mouse device is placed, the first pressing part or the second pressing part is moved toward the first switch or the second switch in order to trigger the first switch or the second switch.

Abstract: A power-saving method for a wheel mouse is provided. The power-saving method is used to control the illumination cycle of a light emitter by judging whether a scroll wheel is triggered or judging whether the output signal from the light receiver is changed. In a case that the illumination cycle of the light emitter is a shorter second cycle, the light emitter can quickly generate the optical signal. Consequently, the optical signal is not lost, and the possibility of erroneously operating the wheel mouse is eliminated. Whereas, in a case that the illumination cycle of the light emitter is a longer first cycle, the controlling unit can reduce the power consumption in order to achieve the power-saving efficacy.
