Abstract: PURPOSE:To improve the recording efficiency by preventing a recording operation from starting even when a momentary noise is inputted at more than a starting level and starting the recording operation when a sound input signal at more than the starting level is continously inputted for a prescribed period of deciding time. CONSTITUTION:A CPU (central processing unit; deciding means and control means) is set in advance with a time limit for measuring such a case that a sound input signal at more than the starting level is not continuously inputted as the 2nd period of deciding time. Then, the measurement is performed until a new detecting signal is inputted within the limit of the 2nd period of deciding time, and when the new sound input signal at more than the starting level is inputted within the 2nd period of deciding time, a detecting signal from a detector 3 is sent to the CPU 6. Then, when the continuation time is shorter that the 1st period of deciding time, a new sound input signal is decided as a momentary noise by the CPU 6. Moreover, when the continuation time is longer than the 1st period of deciding time, a new sound input signal is decided as a voice such as an utterance, and an analog-signalized data from a D/A converter 8 is recorded to a magnetic tape. By this method, unnecessary recording is excluded, and the recording efficiency is improved.
