ABSTRACT:
An input device including a case defining an opening, a bearing member pivotally mounted in the case about an axis and disposed adjacent to the opening, a roller rotatably disposed on the bearing member and having a portion exposed through the opening, an encoder disposed adjacent the axis of the bearing member and coupled to the roller by a belt, and a push button switch disposed to contact a portion of the bearing member away from the axis, such that manual rotation of the roller causes the belt to rotate the encoder, thereby producing a first output signal, and pressing the roller causes activation of the push button switch by pivoting the bearing member, thereby producing a second signal. A water receiving member is disposed in the case between the bearing member and roller. The water receiving member has a main chamber into which is disposed the roller, and a subchamber connected to the main chamber by a cut-out passage. A drainage passage is formed in the case and connected to the subchamber for allowing water to exit the main chamber.
