Abstract
A wheel mouse includes a mouse case, a base, a circuit board, an encoder, a fixing element, a wheel, a switch element and a spring. The circuit board is disposed on the base. The fixing element includes a ring-shaped part and a hollow post. The encoder is accommodated within the ring-shaped part. The wheel includes a rotating shaft and a receptacle. The ring-shaped part of the fixing element is accommodated in the receptacle. A first end of the rotating shaft is inserted into the encoder perforation. The switch element is mounted on the circuit board and under a second end of the rotating shaft. The spring is inserted into the hollow post for offering an elastic force on the fixing element. Since the encoder is accommodated within the wheel, the overall volume of the wheel mouse is reduced and the loading on the wheel is reduced.
