Abstract

PURPOSE:To read the contents of a recorder into a memory when processing is started again and to realize the same state as that obtained right before the cut-off of the power supply although the contents of the memory are erased by the cut-off of the power supply, by recording the contents of the memory to the recorder before the cut-off of the power supply. CONSTITUTION:The interval is measured for the key input through a key encoder 11, and a detection signal is supplied to a process circuit 12 when the interval becomes longer than the prescribed value. Then a recorder 3 is set to a recording mode by a command given from the circuit 12, and at the same time the contents of a memory incorporated into the circuit 12 are read in due order to be converted into the tone signals. These tone signals are supplied to the recorder 3. When the reading is over for the incorporated memory, the command given from the circuit 12 is supplied to a control circuit 24 through circuit 14 to cut off the supply of voltage. Furthermore, a keyboard 1 is operated, and accordingly a signal showing that the key has been operated by the encoder 11 is supplied to the circuit 24 to start the supply of voltage.
