Abstract
An optical mouse testing device includes a testing frame, a control unit, a transmission unit, a rolling unit and an indicating unit. An optical mouse to be tested is placed on an upper surface of the testing frame. The control unit is used for driving the transmission unit according to the route coordinate data. The transmission unit is used for rendering a rolling motion of a ball of the rolling unit. The optical mouse senses the rolling motion of the ball, thereby providing a route coordinate data to the control unit. The control unit compares the route control signal with the route coordinate data, thereby generating an indicating signal to indicate a testing result.
Claims10
An optical mouse testing device comprising:
- a testing frame comprising a testing hole, an upper surface and a lower surface, wherein an optical mouse to be tested is supported on said upper surface, said testing hole is arranged in a center of said testing frame, said lower surface is parallel with said upper surface, and a sensor of said optical mouse is disposed over said testing hole for providing a route coordinate data;
- a control unit disposed on said testing frame for receiving said route coordinate data and providing a route control signal and an indicating signal;
- a transmission unit disposed on said lower surface of said testing frame and electrically connected with said control unit, wherein said transmission unit comprises two rolling shafts, and said two rolling shafts are rotated according to said route control signal;
- a rolling unit disposed on said lower surface of said testing frame, and comprising a ball seat and a ball, wherein said ball seat is disposed under said testing hole for supporting said ball, and said ball is contacted with said two rolling shafts;
- and
- an indicating unit disposed on said testing frame and electrically connected with said control unit, wherein when receiving said indicating signal, said indicating unit generates a corresponding testing light prompt,
- wherein when said two rolling shafts are rolled to render a rolling motion of said ball, said sensor of said optical mouse senses said rolling motion of said ball to generate said route coordinate data, and said control unit compares said route control signal with said route coordinate data, thereby generating said indicating signal to indicate a testing result.
An optical mouse testing method, comprising steps of:
- (1) placing a sensor of an optical mouse to be tested over a testing hole of a testing frame;
- (2) driving a transmission unit according to a route control signal, thereby rolling two rolling shafts of said transmission unit;
- (3) rendering a rolling motion of a ball of a rolling unit by rolling said two rolling shafts;
- (4) allowing said senor of said optical mouse to sense said rolling motion of said ball, thereby providing a route coordinate data;
- (5) comparing said route coordinate data with said route control signal, thereby generating an indicating signal;
- and
- (6) generating a testing light prompt according to said indicating signal.
