PURPOSE:To update and reproduce optionally voice information having an optional content and length by providing a semiconductor storage element storing a voice signal and a counter control circuit storing the length of information and controlling the storage element at a time remained in the control circuit. CONSTITUTION:When a recording instruction is applied to a control circuit 11, a pulse from a frequency divider 6 is counted with the start of recording. A count stop signal is transmitted from the control circuit 11 by recording stop instruction so as to hold the counted number in a control circuit 10. The recording stop instruction resets a counter 9 at the reproducing operation and starts counting the pulse from the frequency-divider 6 and gives its output to the control circuit 11. The circuit 11 sets an RAM 8 to the read mode so as to transmit the data in the RAM 8 regularly to a data latch circuit 12. A read end signal is outputted when the count number stored in the control circuit 10 and the number of the counter 9 are coincident and resets the counter 9. When the counter 9 receives a reset signal, the reproduction is started again from the beginning of the information and this operation is continued until the next recording instruction is given. |
