Mouse device

A mouse device in communication with a computer system for controlling movement of a cursor of the computer system, the mouse device comprising:

• a mouse casing comprising a receiving recess, wherein the receiving recess is formed in a bottom part of the mouse casing and exposed outside the mouse casing;
• a circuit board disposed within the mouse casing;
• a first sensing module disposed on the circuit board, wherein a part of the first sensing module is selectively exposed outside the bottom part of the mouse casing;
• a second sensing module disposed on the circuit board, wherein a part of the second sensing module is selectively exposed outside the bottom part of the mouse casing;
• and
• a switching module partially received within the receiving recess and partially exposed outside the bottom part of the mouse casing, wherein at least one of the first sensing module and the second sensing module is exposed outside the bottom part of the mouse casing through the switching module, so that a moving resolution of the mouse device is adjustable,
• wherein the mouse casing comprises:
• a first casing opening aligned with the first sensing module and disposed within the receiving recess;
• a second casing opening aligned with the second sensing module and disposed within the receiving recess;
• and
• a track disposed within the receiving recess,
• wherein the first sensing module is partially exposed outside the bottom part of the mouse casing through the first casing opening, and the second sensing module is partially exposed outside the bottom part of the mouse casing through the second casing opening,
• wherein the switching module comprises:
• a switching plate received within the receiving recess, and partially inserted into the groove, wherein the switching plate is movable or rotatable relative to the mouse casing;
• a detecting element disposed on the circuit board and located beside the track, wherein when a rotating status and a moving status of the switching plate is detected by the detecting element, a detecting signal is generated by the detecting element;
• and
• a controlling unit disposed on the circuit board and electrically connected with the detecting element, the first sensing module and the second sensing module, wherein the controlling unit controls operations of the first sensing module and the second sensing module according to the detecting signal,
• wherein the switching plate comprises:
• a plate body disposed within the receiving recess, wherein the plate body is movable within the receiving recess and relative to the mouse casing;
• and
• a protrusion post disposed on the plate body and inserted into the track, wherein as the switching plate is moved relative to the mouse casing, the detecting element is triggered by the protrusion post, wherein when the plate body is moved to a first position of the receiving recess, the first sensing module is exposed outside the bottom part of the mouse casing, wherein when the plate body is moved to a second position of the receiving recess, the second sensing module is exposed outside the bottom part of the mouse casing,
• wherein when the plate body is moved to a third position of the receiving recess, both of the first sensing module and the second sensing module are exposed outside the bottom part of the mouse casing.
