PURPOSE:To enable the input of a lot of data at high speed by a method wherein data from the outside is inputted through the intermediary of an acoustic transducer incorporated in the body of a clock. CONSTITUTION:When an acoustic signal is inputted in an acoustic transducer 101 from the outside, it is amplified 103, transduced 104 into a binary code, and stored in a memory 105. When an alarm sound is generated, the acoustic transducer 101 is connected to an alarm sound driving circuit 108. |
