<p>PURPOSE:To execute easily an inspection of an intermusic detecting device by providing an intermusic part of a level of the maximum value of an allowable value of an intermusic detecting level of an itermusic detecting device to be inspected. CONSTITUTION:First of all, the first signal part 3 is reproduced, an intermusic detecting device detects a signal, and subsequently, reproduces an intermusic part 4, and an intermusic detecting signal is outputted from the intermusic detecting device, by which a prescribed operation such as switching of a tape runnig mode, etc. is executed. In this case, if a signal detecting level of the intermusic detecting device is larger than a signal level D being an allowable value, the first and the second signal parts 3, 5 detect no signal, and even if the intermusic part 4 is reproduced, no intermusic detecting signal is outputted. Also, when an intermusic detecting level of the intermusic detecting device is smaller than a signal level C being an allowable value, even if the intermusic part 4 is reproduced, a noise is detected and it is decided that a melody exists, therefore, no intermusic detecting signal is outputted. In this way, it can be executed easily to observe a running mode, etc. of a tape recorder, and to guarantee as an intermusic detecting device of a normal intermusic detecting level.</p> |
