ABSTRACT:
A connector mounted on a system board has terminals the number of which corresponds to the total sum of key matrix control signal lines and pointing stick control signal lines. The key matrix control signal lines and pointing stick control signal lines are connected together to the connector. Both a keyboard interface and a pointing stick interface can thus be achieved by the single connector, resulting in improvement in mounting efficiency, decrease in cost and simplification in assembly process.
