<p>PURPOSE:To obtain a high-speed erasion mechanism which is free from misoperations by providing an operating member for prevention of shift of erasion head containing a preventing bar for sift of an erasion member. CONSTITUTION:When a rewind operating member 5 is pushed toward an arrow head (b), the shift of an erasion head support member 21 is prevented toward the arrow head (b) by a preventing bar 12b. Thus an erasion head 11 has no forward shift and this eliminates such a case where a recording head is erased by mistake with a contact with a magnetic tape. The member 5 is pushed toward the arrow head (b) with push of an erasion head shift preventing member 12. In this case, the bar 12b of the member 12 is shifted toward (b) to avoid the prevention of the shift of the head 11 toward the (b) together with the member 5. Thus the head 11 moves up to a position where a contact is secured with the tape. Then the member 12 interlocks a preventing bar 14d via a boss 12a; while the member 5 is locked by a rubbing member 7.</p> |
