ー１．２に当接させるクリーニングアームテアル。FIG. 3d is a side view of a conventional magnetic powder removal device. In FIG. 3 δ, 1 is a rotary cylinder that has a magnetic head (not shown) and is rotatable at a predetermined rotation speed, 2 is a fixed cylinder that is coaxially provided with the rotary cylinder 1 and is in an integral relationship; 4 is a cylindrical member rotatably provided on an axis different from the rotation axis of the rotary cylinder 1; 6 is a cylindrical member that holds a support shaft 10 that pivotally supports the cylindrical member 4, and is in contact with both cylinders 1.2; Cleaning arm teal.

材４の使用回数が増えるに従って磁性粉が固着して汚れ
、逆に磁気ヘッドに磁性粉を付着したりして磁性粉除去
のクリーニング効果か少なくなるという問題があった。The cleaning arm 5 is rotated when the rotating cylinder 1 rotates, and the cylindrical member 4 is brought into contact with the rotating cylinder 1 and the fixed cylinder 2 at a ratio of about 7=3. A rotational force is applied to the cylindrical member 4 by the rotating cylinder 1, and a frictional load is applied to the fixed cylinder 2, so that the rotational speed is lower than that of the rotating cylinder 1. and,
Due to this difference in rotational speed, the magnetic head on the rotating cylinder 1 comes into contact with the cylindrical member 4, and the magnetic powder attached to the magnetic head and around the head is removed. Problems However, in the above-mentioned conventional configuration, the cylindrical member 4 can only come into contact with the magnetic head on the same circumference, so as the cylindrical member 4 is used more often, magnetic powder sticks and becomes dirty, and conversely, the magnetic head There is a problem in that the cleaning effect of removing magnetic powder is reduced due to the adhesion of magnetic powder to the magnetic powder.

円筒状部材４を形成する発泡材の摩耗が激しく、ヘッド

かいという問題があった。Furthermore, as shown in the cross-sectional view of the cylindrical member 4 in Figure 3,
There is a problem in that the foam material forming the cylindrical member 4 is severely worn, and a V-groove corresponding to the head trajectory is formed, resulting in a short lifespan of the cylindrical member.

る。Means for Solving the Problems To achieve this object, the magnetic recording/reproducing device of the present invention has a cylindrical member in contact with both cylinders, and a support shaft that pivotally supports the cylindrical member rotates the cylinder. It is installed parallel to the axis and inclined in the direction of rotation of the rotating cylinder.

ないため、円筒状部材の摩耗を少なく、均一にできる。Function: This configuration allows the cylindrical member to rotate while moving in the axial direction, so the magnetic head does not come into contact with the cylindrical member only on the same circumference, but evenly around the circumference within the movement range. Even if magnetic powder sticks to one part, it can be cleaned in another part. Furthermore, since the magnetic head does not contact only the same portion, wear of the cylindrical member can be reduced and made uniform.

ダー１．２に当接したシ、離したシすることができる。First, the method of abutting the cylindrical member 40 will be explained with reference to FIGS. 1d and 1b. The loading gear 6 is rotated during a loading operation in which a magnetic tape (not shown) is wound around the rotating cylinder 1 and the stationary cylinder 2. This loading gear 6 is provided with a protrusion 7, and this protrusion 7 is slidably inserted into a groove 9 provided in the cleaning rod 8. As the loading gear 60 rotates, the protrusion 7 moves, slides in the groove 9, and moves the cleaning rod 8. This movement of the cleaning rod 8 is transmitted to the cleaning arm 6 which holds the fixed shaft 10 that pivotally supports the cylindrical member 4, so that the cylindrical member 4 is brought into contact with and released from both cylinders 1.2. Can be done.

向に回動させて、第１図すを経由して第１図ａに戻す。FIG. 1a shows the situation before the start of the loading operation, in which the cylindrical member 4 is separated from both cylinders 1.2. When the loading operation starts, the loading gear 6 rotates clockwise, and the cylindrical member 4 gradually approaches both cylinders 1.2, and in the middle of the loading operation, the best contact state is reached as shown in FIG. It is said that The pressure contact force at this time is
It is provided by a torsion coil spring 11. Note that the time during which they are in contact is about 2 to 3 seconds at most. When the loading operation is completed, the cylindrical member 4 is moved as shown in FIG.
away from both cylinders 1.2 as shown. However, the position of the protrusion 7 at this time is above the groove 9 in the drawing. Incidentally, during an unloading operation to unwind the magnetic tape, the loading gear 6 is rotated counterclockwise to return to FIG. 1A via FIG. 1S.
このときの突起部７の位置は、ローディング動作する前
の位置すなわち図面で言えば溝部９の下側にある。The position of the protrusion 7 at this time is the position before the loading operation, that is, below the groove 9 in the drawing.
リコイルバネ等は円筒状部材４を回動させる回動手段を
構成するものである。The recoil spring and the like constitute a rotating means for rotating the cylindrical member 4.
次に、第２図ａ、ｂにおいて円筒状部材４が両シリンダ

。Next, the operation of the cylindrical member 4 in a state where the cylindrical member 4 is in contact with both cylinders 1.2 in FIGS. 2a and 2b will be described. As shown in FIG. 2a, the cylindrical member 4
By making the axis center 3a of the rotating cylinder 1 slightly inclined with respect to the rotating axis center 3b of the rotating cylinder 1, the rotational force A of the rotating cylinder 1 becomes the force that rotates the cylindrical member 4, as shown in Pect/L/ B, and a force C that moves in the axial direction shown by arrow 12. That is, in the separated state before contact, the cylindrical member 4 falls under its own weight and is in the lower position, and when it contacts, it moves in the direction of arrow 12 and moves to the upper position.
このように円筒状部材４が下部位置から上部位置に移動
するようにしたため、磁気ヘッドが円筒状部材４の異な
る部分に接触するようにでき、飛躍的にクリーニング効
果を高めることができる。Since the cylindrical member 4 is moved from the lower position to the upper position in this manner, the magnetic head can be brought into contact with different parts of the cylindrical member 4, and the cleaning effect can be dramatically improved.
また、第２図すに示す円筒状部材４の断面図からも判る
ように、円筒状部材４の摩耗は移動範囲内の磁気ヘッド

ここで、本発明と従来例との差異を回転軸と支持軸１０
との関係において説明すると、従来例は、第１の平面と
第２の平面に対して回転軸と支持軸１０とが平行となる
ように設けられたものである。Here, the difference between the present invention and the conventional example is that the rotating shaft and the supporting shaft 10
To explain in relation to this, in the conventional example, the rotation axis and the support shaft 10 are provided so as to be parallel to the first plane and the second plane.
これに対し本発明は、第１の平面は仮想平面であり、こ
の仮想平面に対して支持軸１ｏを傾けたものである。そ
して、傾ける方向は回転シリンダ１の回転方向である。In contrast, in the present invention, the first plane is a virtual plane, and the support shaft 1o is tilted with respect to this virtual plane. The direction of inclination is the direction of rotation of the rotary cylinder 1.
従って、第２図ａもまた第２の平面から見た側面図であ
る。FIG. 2a is therefore also a side view from a second plane.
発明の効果

きる等、その実用的効果は大きい。Effects of the Invention As described above, according to the present invention, since the cylindrical member is moved in the axial direction (rotating cylinder, substantially concave rotational axis direction), the magnetic head can come into contact with different parts of the cylindrical member. This has great practical effects, such as dramatically increasing the cleaning effect and greatly extending the life of the cylindrical member.
