Data input apparatus










Image Number 3 for United States Patent #4887082.

A data input apparatus comprising a plurality of input keys. A determiner determines whether the time required for executing the function of a pressed key is long or short. In response to the results of determination of the determiner, a first timekeeping device produces a first predetermined time signal, and a second timekeeping device produces a second time signal shorter in duration than the predetermined time signal. A CPU receives data representative of the pressed key at the end of the first or second time signal. In response to receipt of the data by the CPU, a third timekeeping device produces a third time signal shorter in duration than the second time signal. At the end of this third time signal, the CPU receives the data for as long as the key continues to be pressed. The third timekeeping device may include two different timekeeping elements which produce different time signals in order to be used in conjunction with the first and second timekeeping devices, respectively. Alternatively, a computer may perform the same function as mentioned above, using software techniques.
