Claims

[Scope of utility model registration request]

In a tape recorder equipped with a recording function, a head holder supporting an erasing head is mounted on a recording operation member, and in conjunction with the operation of this recording operation member, the head holder is guided by a guide portion formed on a chassis to erase the erase head. A tape recorder comprising an erasing head mechanism that brings the head into contact with and separates it from the tape.
