けることができる。 That is, an embodiment of the present invention will be described using FIGS. 2 to 4. Reference numeral 1 denotes a head base. Although not particularly shown, a magnetic tape for recording/reproducing, a pinch roller, etc. are mounted on the head base 1, and the head base 1 can be moved between a stop position and a recording/reproducing position. Further, the head base 1 is provided with a locking hole 2, a mounting shaft 3, a locking pin 4, and a guide hole 5. Reference numeral 6 denotes a tape guide plate made of synthetic resin, and locking legs 7, 7 provided on the tape guide plate 6 are locked in the locking holes 2 of the head base 1, so that the tape guide plate 6 is mounted on the head base 1. It is. Reference numeral 8 denotes an erasing head mounting member made of synthetic resin, and the erasing head mounting member 8 includes a base 9 on which the erasing head 14 is mounted and a spring piece 10 for biasing the erasing head 14 in the direction of contacting the magnetic tape. It is molded into. An arm portion 1 for attaching an erasing head 14 is provided at one end of the base portion 9.
1, 11 and a positioning protrusion 12 are provided, and the other end is provided with a hole 13 to be attached to a mounting shaft 3 provided on the head base 1. The erasing head 14 made of a permanent magnet has a hole 15 approximately in the center thereof.
is provided, and the hole 15 engages with the protrusion 12. To attach the erasing head 14 to the erasing head mounting member 8, the arms 11, 11 are pushed outward from above the base 9, and the holes 15 and the protrusions 12 are engaged. 11 returns to its original position due to its own elasticity, and the erasing head 14 can be attached.
16は録音操作に伴なつて移動する作動ピン
で、該作動ピン16はヘツドベース1に設けたガ
イド孔5より突出し、消去ヘツド取付部材8と係
合するものである。 Reference numeral 16 denotes an operating pin that moves with the recording operation. The operating pin 16 protrudes from the guide hole 5 provided in the head base 1 and engages with the erasing head mounting member 8.
次に、消去ヘツド取付部材8の取付けについて
説明すると、ヘツドベース1に設けた取付軸3に
基部9の孔13を係合し、取付軸3の孔3aに係
止ビス3bを嵌合すると共にバネ片10の遊端を
係止ピン4に係止すればよいものである。 Next, to explain how to attach the erasing head attachment member 8, the hole 13 of the base 9 is engaged with the attachment shaft 3 provided on the head base 1, the locking screw 3b is fitted into the hole 3a of the attachment shaft 3, and the spring is attached. It is only necessary to lock the free end of the piece 10 to the locking pin 4.
そして、第3図に示すように再生操作した場合

14は磁気テープと接触し、消去作業を行うもの
である。 When a playback operation is performed as shown in FIG. 3, the head base 1 moves forward to move the magnetic head and pinch roller to the playback position, but the erase head 1
4 does not move forward because the operating pin 16 does not move. Furthermore, as shown in FIG. 4, when a recording operation is performed, the head base 1 and the operating pin 16 move, so the erasing head mounting member 8 follows the head base 1 due to the biasing force of the spring piece 10, and the erasing head 14 is magnetically moved. It comes into contact with the tape and performs the erasing operation.

できる等の効果を奏するものである。 As mentioned above, in the present invention, the erasing head mounting member 8, which consists of the base 9 on which the erasing head 14 is attached and the spring piece 10 for biasing the erasing head 14 in the direction of contacting the magnetic tape, is integrally molded from synthetic resin. However, since the base 9 is rotatably attached to the head base 1 and the spring piece 10 is locked to the head base 1, it can be handled as one component, and the work of attaching a coil spring as in the conventional case can be omitted. It is effective.
