Abstract:
A keyboard testing apparatus for testing a keyboard having at least one indicator and a plurality of keys, comprising:a pair of clamping members spaced from each other by a distance sufficient to accommodate the keyboard;a retaining device for firmly retaining the keyboard in position between the clamping members;an indicator test device comprising an optic sensor corresponding to the indicator of the keyboard for detecting light emitted from the indicator which generates an indicator test signal;a key testing device comprising a plurality of key actuators each having a movable shaft having an end movable relative to the keys for selectively actuating and deactuating at least one of the keys, the actuation of the key generating a key test signal;a conveying device comprising a rail reciprocally movable in a direction parallel to the keyboard, the rail being coupled to the key testing device for moving the key testing device relative to the keyboard;a signal adapter adapted to releasably mate with an output connector of the keyboard;a control unit electrically connected to the signal adapter and the indicator test device for receiving the key test signal and the indicator test signal therefrom whereby the control unit determines if the keys and the indicator are normal; and,a warning device which is controlled by the control unit to generate a warning signal when the control unit determines that any key or any indicator does not function normally.
