Abstract (en)
[origin: EP1078822A2] The device includes user-operated keys (2,3,4,6,7,8,11), a switch that is switchable between two states by key operation, a management circuit (13,14,15) for monitoring the operation of the keys and outputting a monitoring result signal to the computer (12). The management circuit does not output a result signal while the state of the switch remains unchanged, or changes over from the state associated with the operated key to the state associated with a non-operated key. The management circuit outputs a result signal if the switching contact changes over from the state associated with the non-operated key to the state associated with the operated key. A bus such as a CAN or USB (16) may be used for the communication with the computer.
