  • Patent number: 10599237
    Abstract: An input device includes a housing, a wheel, a mode switch, a carrier, and an abutting assembly. The wheel is rotatably disposed on the housing and capable of rotating relative to the housing based on an axis. The wheel has a first gear structure and a second gear structure. The mode switch is disposed on the housing. The carrier is movably disposed on the housing and engaged with the mode switch. The abutting assembly is disposed on the carrier. While moving to a first position relative to the housing, the carrier switches the mode switch to a first mode and makes the abutting assembly contact the first gear structure. While moving to a second position relative to the housing, the carrier switches the mode switch to a second mode and makes the abutting assembly contact the second gear structure.
