PURPOSE:To make the beginning and end of a reproducing signal clear, be providing a section between the end and beginning of a stored signal, in reading and reproducing the signal. CONSTITUTION:A signal received with a redio reception circuit 1 is stored in a random access memory RAM 5 while being revised sequentially and repetitively. A fixed section (space and alarm sound and the like) is provided between the beginning and end of a signal stored in the RAM 5, and the stored signal can be read out and reproduced arbitrarily, repetitively and sequentially. The circuit consists, for example, of a radio reception circuit 1, an amplifier circuit 2, an RAM 5, a counter 6 for an address signal, a microcomputer 8, and an alarm signal generating circuit 10, and when a switch is selected to the (n) terminal, the storage to the RAM 5 is done and selected to the (r) terminal, the generation of alarm tone and the readout of a storage signal can be done. |
