Patent ID: 8117504

Claim:
An automatic keyboard testing system for automatically testing a keyboard circuit board of a keyboard device, said keyboard circuit board comprising multiple key intersection points correlating to respective key scanning codes, said automatic keyboard testing system comprising: a computer; an automatic testing program installed in said computer for generating a testing signal and having a predetermined time period; and a testing frame connected to said computer and said keyboard circuit board for generating a simulating signal according to said testing signal and conducting a key intersection point corresponding to said simulating signal, so that said keyboard circuit board output a key scanning code corresponding to said conducted key intersection point to said computer, wherein said automatic testing program outputs an error message if said key scanning code has not been transmitted to the computer within said predetermined time period, wherein said testing frame further comprises: a control panel for generating said simulating signal according to said testing signal; multiple thimbles contacted with said keyboard circuit board for transmitting said simulating signal to said keyboard circuit board; a power wire connected with said computer for transmitting electricity from said computer to said testing frame; and a signal wire connected with said computer for transmitting said testing signal; wherein said control panel further comprises an analog switch connected with said thimbles, wherein said analog switch is connected with multiple key intersection points after said keyboard circuit board is placed on said testing frame and contacted with said thimbles.
