5 has been applied. In this embodiment, a scale 15 up to "50" is provided. A notch 16 formed in the drive shaft engaging portion 9 indicates each position of the scale 15.
以上のような構成を有する本考案の磁気シート
ジヤケツトの使用例について説明する。 An example of the use of the magnetic sheet jacket of the present invention having the above configuration will be described.
まず、ジヤケツト筐体１を磁気記録再生装置
（図示せず）内に装填すると、上記磁気記録再生

目盛１５の「１」のポジシヨンを指す。 First, when the jacket housing 1 is loaded into a magnetic recording/reproducing apparatus (not shown), the display plate drive shaft 17 provided on the magnetic recording/reproducing apparatus side is inserted into the drive shaft engaging portion 9 of the rotary display plate 10. inserted into. At the same time, the rotary drive shaft 18 of the magnetic recording/reproducing device is inserted into the drive hole 5 of the reinforcing member 6, as shown by the dashed line in FIG. Display board drive shaft 17
is inserted into the drive shaft engaging portion 9, the outer peripheral surface of the drive shaft 17 has a shape corresponding to the shape of the drive shaft engaging portion 9 of the rotary display board 10, as shown in FIGS. 4 and 5. Since the protrusion 19 is provided in such a manner that the protrusion 19 is inserted into the notch 16 of the protrusion 19. At this time, the notch 16 of the drive shaft engaging portion 9 is
Points to the "1" position on the scale 15.
次に、磁気記録再生装置側からの回転駆動力に
よつて磁気シート２が回転駆動されると、窓部３
内に挿入されている磁気ヘツド４により磁気シー
ト２上に所定の映像信号が１つの環状の記録トラ
ツクを形成するように磁気記録される。 Next, when the magnetic sheet 2 is rotationally driven by the rotational driving force from the magnetic recording/reproducing device side, the window portion 3
A predetermined video signal is magnetically recorded on the magnetic sheet 2 by a magnetic head 4 inserted therein so as to form one annular recording track.
磁気シート２が１回転して１つの記録トラツク
が記録されると、磁気ヘツド４が磁気シート２の
半径方向に１トラツク分移動する。磁気ヘツド４
が移動すると、これに連動して表示板駆動軸１７

のポジシヨンを駆動軸係合部９の切欠部１６が指
標する位置まで回転する。 When the magnetic sheet 2 rotates once and one recording track is recorded, the magnetic head 4 moves one track in the radial direction of the magnetic sheet 2. magnetic head 4
moves, the display board drive shaft 17 moves in conjunction with this movement.
rotates slightly clockwise in Figure 4. The amount of rotation of this drive shaft 17 is set to correspond to the interval between each position on the scale 15, so it is "2".
The position is rotated to the position indicated by the notch 16 of the drive shaft engaging portion 9.
この後、磁気シート２が１回転すれば、磁気ヘ
ツド４により、第２の記録トラツクがこの磁気シ
ート２上に磁気記録される。この場合、ストツパ

１ａと間欠的に係合するので、駆動軸係合部９の
切欠部１６を目盛１５の所定のポジシヨンに確実
に位置決め保持させることができる。 Thereafter, when the magnetic sheet 2 rotates once, a second recording track is magnetically recorded on the magnetic sheet 2 by the magnetic head 4. In this case, the engaging portion 12a of the stopper member 12 meshes with the serrated portion 11a formed on the rotating gear 11 of the rotating display plate 10, and the serrated portion 11a is engaged with the serrated portion 11a formed on the rotating gear 11 of the rotating display plate 10.
1a, the notch 16 of the drive shaft engaging portion 9 can be reliably positioned and held at a predetermined position on the scale 15.
このようにして、環状の記録トラツク数に対応
した目盛１５のポジシヨンが例えば第４図中破線
で示すように回転表示板１０の切欠部１６で目視

から取り出した後も、駆動軸係合部９の切欠部１
６はストツパー部材１２の係合作用により所定の
目盛１５のポジシヨンを指標保持し続けるので、
記録済の環状の記録トラツク数を再確認すること
ができる。 In this way, the position of the scale 15 corresponding to the number of annular recording tracks can be visually observed at the notch 16 of the rotary display plate 10, as shown by the broken line in FIG. You can easily check the number of recorded tracks. Furthermore, even after the jacket housing 1 is removed from the magnetic recording/reproducing apparatus, the notch 1 of the drive shaft engaging portion 9 remains intact.
6 continues to maintain the predetermined position of the scale 15 by the engagement action of the stopper member 12.
You can reconfirm the number of recorded annular recording tracks.
なお、ジヤケツト筐体１を磁気記録再生装置に
装填した場合において、回転表示板１０の切欠部
１６が目盛１５の「１」以外のポジシヨンを指標

で、表示板駆動軸１７はその位置で駆動軸係合部
９内に挿入される。磁気ヘツド４は上記係合部９
内に表示板駆動軸１７が挿入されているときのみ
磁気記録するようになつているので、上記係合部
９内に上記駆動軸１７が入つた後磁気シート２上
に映像信号等を磁気記録するので、既に映像信号
等を記録した記録済の記録トラツク上にさらに映
像信号等の記録を防止する。 Note that when the jacket housing 1 is loaded into a magnetic recording/reproducing device, when the notch 16 of the rotary display board 10 indicates a position other than "1" on the scale 15, the display board drive shaft 17 will not rotate. Although it cannot be inserted into the drive shaft engaging portion 9 of the display board 10, the automatic feed mechanism provided in the playback device steps feeds the protrusion 19 of the drive shaft 17 to a position where it is inserted into the notch 16. , so the display panel drive shaft 17 is inserted into the drive shaft engaging portion 9 at that position. The magnetic head 4 is connected to the above-mentioned engaging portion 9.
Since magnetic recording is performed only when the display board drive shaft 17 is inserted into the engaging portion 9, video signals, etc. are magnetically recorded on the magnetic sheet 2 after the drive shaft 17 is inserted into the engaging portion 9. Therefore, further recording of a video signal, etc. is prevented on a recorded recording track on which a video signal, etc. has already been recorded.

とができ、実用上極めて有効なものである。 As is clear from the above description, since the present invention is provided with a display means for displaying the number of annular tracks in the jacket housing, the recording state (number of annular recording tracks) on the magnetic sheet that cannot be visually recognized from the outside is displayed. can be easily and reliably confirmed with the naked eye. Therefore, it is possible to check, for example, how many annular recording tracks can be magnetically recorded on the magnetic sheet, which is extremely effective in practice.
