なつている。 As shown in the above drawings, a disk-shaped magnetic sheet 2 is rotatably accommodated in a magnetic sheet jacket 1. The magnetic sheet 2 has a large number of concentric recording tracks, and the jacket is placed on each of the recording tracks by one or more magnetic heads provided in a magnetic recording/reproducing device in an electronic camera, for example.

ようになつている。 A drive shaft insertion insertion hole 6 into which the rotary drive shaft 4 is inserted is formed through the reinforcing member 5 at approximately the center thereof. 4a, the magnetic sheet 2
Positioning surfaces 7, 7 for aligning the center of rotation with the axis of the drive shaft 4 are formed approximately in a V-shape. The center of rotation of the magnetic sheet 2 with respect to the rotary drive shaft 4 is determined using the positioning surfaces 7, 7 as a reference. Further, an elastic portion 8 for elastically pressing the drive shaft 4 against the positioning surfaces 7, 7 is formed at a position within the insertion hole 6 facing the positioning surfaces 7, 7. The elastic portion 8 is formed by providing a long hole 9 on the side opposite to the pressing surface 8a that contacts the outer circumferential surface 4a of the drive shaft 4. The length of the straight line R' connecting the center a of the pressing surface 8a and the rotation center X of the magnetic sheet 2 is:
The radius R is set to be shorter than the length of the radius R of the drive shaft 4. Therefore, when the drive shaft 4 is inserted into the insertion hole 6, the outer peripheral surface 4a of the drive shaft 4 can be elastically pressed against the positioning surfaces 7, 7 by the pressing surface 8a of the elastic portion 8.
なお、上記押圧面８ａは、駆動軸４の外周面４
ａとの強固の接触を確保できるように位置決め面
７，７側に突出して形成されることが望ましい。 Note that the pressing surface 8a is the outer circumferential surface 4 of the drive shaft 4.
It is preferable that they are formed to protrude toward the positioning surfaces 7, 7 so as to ensure strong contact with the positioning surfaces 7a.

ことができる。 The positioning surfaces 7, 7 and the elastic part 8 can be integrally molded from a resin material at the same time when the reinforcing member 5 is molded, so manufacturing is easy, and the elastic part 8 is made of a resin material such as plastic. Since it is made of material, it is possible to obtain an elastic effect with the material itself.

When this is attached to a magnetic recording/reproducing device, it passes through the center hole 10 formed in the center of the jacket 1 and into the insertion hole 6 of the reinforcing member 5 provided at the center of rotation of the magnetic sheet 2 in the jacket 1. Rotation drive shaft 4 is inserted. Then, since the tip of the drive shaft 4 is generally formed into a conical shape, the drive shaft 4 is smoothly inserted into the insertion hole 6 along the conical surface. When the drive shaft 4 is inserted, the pressing surface 8a of the elastic part 8 elastically presses the outer peripheral surface 4a against the positioning surfaces 7, 7, so that the rotation center X of the magnetic sheet 2 is aligned with the axis of the drive shaft 4. In addition, since the drive shaft 4 is held between the positioning surfaces 7, 7 and the elastic portion 8, the magnetic sheet 2 can be held without wobbling.

できる。 Although this embodiment shows an example in which the elastic part 8 is formed so as to completely separate the elongated hole 9 and the insertion hole 6, the elastic part 8 is not limited to this example. A similar effect can be obtained even if the elastic portion 11 is formed by each of the formed protrusions 11a and 11b.

As is clear from the above description, the present invention forms a positioning surface and an elastic part in the insertion hole for inserting the drive shaft of the reinforcing member attached to the center of the magnetic sheet. When the drive shaft is inserted into the drive shaft, the elastic part elastically presses the outer peripheral surface of the drive shaft against the positioning surface, so that the center of rotation of the magnetic sheet can be easily and quickly aligned with the axis of the drive shaft without any play. You can match your heart.
