Claims

[Claims for Utility Model Registration] A head base on which a magnetic head is mounted is arranged in a first position where the magnetic head contacts the first magnetic tape and a second position where the magnetic head does not contact the first magnetic tape. a head drive mechanism that moves the head base or the pinch roller between a third position where the pinch roller is pressed against the capstan and a fourth position where the pinch roller is moved away from the capstan; an assisting means for assisting at least one movement, and a reproducing means capable of reciprocating reproducing operation of reproducing information by running the first magnetic tape in both forward and reverse directions; The reproduction signal from the first magnetic tape is transmitted to the second magnetic tape.
In a magnetic recording and reproducing device which is equipped with a recording means for recording on a magnetic tape and has an answering machine function, when the answering machine function is specified and a level signal from the telephone line is detected, the assisting means is activated. , driving at least one of the head drive mechanism or the pinch roller drive mechanism by the assist means to put the first magnetic tape in a playback state in one direction, and reverse the playback at the end of the magnetic tape. When the starting end of the first magnetic tape is reached, the head base is placed in the second position by stopping the operation of the assist means, or the head base is placed in the second position, or the head base is placed in the second position by A magnetic recording/reproducing device characterized in that the roller is placed in the fourth position and placed in a standby state.
