Abstract:
1. A mouse with a direction-switch device for use with an electronic device comprising: a) a case; b) a roller rotatably positioned in a bottom of the case and movable between first and second positions; c) a roller stand located in the case and selectively engaging the roller; d) a PCB located in the case; e) a direction switch gear located on the PCB; f) a mouse IC located on the PCB; g) a sensor located on the PCB and monitoring movement of the roller; and h) a plurality of circuits located on the PCB, at least first and second circuits of the plurality of circuits are connected to the mouse IC and the sensor, at least third and fourth circuits of the plurality of circuits are selectively connected to the mouse IC and the sensor with the direction switch gear located there between, wherein, when the roller is positioned below the roller stand, the roller is in a first position disengaged from the roller stand and the direction switch gear opens the at least third and fourth circuits of the plurality of circuits electrically disconnecting the sensor from the mouse IC, and, when the roller is positioned above the roller stand, the roller is in a second position engaged with the roller stand and the direction switch gear closes the at least third and fourth circuits of the plurality of circuits electrically connecting the sensor to the mouse IC.
