PURPOSE:To feed data stored in a storage means in the speed corresponding to the time data of the stored data, by providing the 2nd word number data at the final part of a data block in advance. CONSTITUTION:A key information generating circuit 9 detects the state of ON/ OFF of each key switch of a key switch group 6 and key information comprising a key code KC, a key impact strength data SD, and a key confirming code KD is outputted accoding to the result of detection. That is, the circuit 9 has three shift registers 9a-9c driven with clock pulse phi0. A control signal generating circuit 18 counts a clock pulse phi1 supplied from a basic clock generating circuit 19 based on the repetitive data BD from a CPU11 and a clock pulse phi2 obtained from the result is outputted to the CPU11 via a bus line 12. |
