きることを特徴とする第２項記載のＤＡＴ。[Claims for Utility Model Registration] (1) A D having a mute section that mutes an audio signal in accordance with a mute on/off signal, and a switching pulse generator that generates a switching pulse according to the rotation of a rotary cylinder.
In the AT, a synchronization section is provided on the input side of the mute on/off signal of the mute section, and when the mute on/off signal is inputted from the outside, this synchronization section synchronizes with the switching pulse generated by the switching pulse generator. A DAT characterized by outputting mute on/off signals to a mute section in synchronization. (2) In a DAT that has a mute section that turns on and off the mute in response to an audio signal according to the mute on/off signal, and a switching pulse generator that generates a switching pulse according to the rotation of the rotating cylinder, the mute on signal is received from the outside. When inputted, the mute-on synchronization part synchronizes with the switching pulse generated by the switching pulse generator and outputs the mute-on signal to the mute part, and when the mute-on signal is inputted from the outside, the switch generated by the switching pulse generator then outputs the mute-on signal to the mute part. a counting section that counts switching pulses; and a mute-off signal generating section that outputs a mute-off signal to the mute section in synchronization with a switching pulse when the counting section counts a predetermined set value. DAT to do. (3) The DAT according to item 2, wherein the set value of the mute-off signal generator is variable.
