Detailed Description of the Invention [Technology of the Invention ■] The present invention relates to a card that can be used as an identification card, a computer game program card, a hospital medical record card, etc., and particularly has a rotating h1 inside. Cards having a recording medium sheet... [Technical background of the invention and its problems] Cards with magnetic tape pasted as an information recording medium, cards with a magnetic recording layer on one side of the entire surface, A recording medium is pasted in the form of a tape.[Cards are also widely known. .

In fact, floppy disks are widely known as computer memory devices, and optical disks are also known as similar recording media.

Writing and reading information to and from a card to which tape is attached is carried out either by moving the write/read head along with the tape, or by fixing the head and moving the card. With such linear relative movement, there is a limit to the movement speed, and the scanning accuracy and uniformity of the head are poor, making it difficult to increase the recording density.Furthermore, there is a limit to increasing the storage capacity. be.

A floppy disk has solved these problems and has increased recording density and storage capacity. However, disc-shaped recording media are unsuitable for use as cards.

[Object of the invention] The present invention has been made to solve the above-mentioned problems.
The aim is to obtain a new card with a high recording density and storage capacity and in the form of a card.

[Summary of the invention]

In order to achieve this object, the card of the present invention consists of a covering material consisting of a pair of opposing rectangular plates of the same size, and a pressure interposed between these covering materials (a peripheral closed area between the two covering materials). It has a flat spacer member that forms a flat space, and a rotary recording medium sheet that is rotatably inserted into the flat space. A connection is provided for connection to a drive source, and at least one of the coverings is formed with an aperture for writing and reading from the rotary recording medium sheet.

[Embodiments of the invention]

Next, the present invention will be described in detail with reference to the drawings. 5. FIG. 1 shows an example of a card according to the present invention. A rotary recording medium sheet 2 is contained within. Main body 1
An opening 3 for loading and reading the rotary recording medium sheet 2 is formed on the 0 surface, and this opening 3 is closed with a transparent sheet material 4 such as glass. It is preferable that the transparent sheet material 41# is made of a transparent sheet material having the same shape and size as the opening 3, and is fitted into the opening 3 to close the opening 3.

As shown in the exploded view of FIG. 2, the main body 1 includes a pair of covering materials HaX1a made of flat rectangular plates of the same shape and size, and a flat frame-shaped spacer member interposed between these covering materials. 1b. The covering 11a and the spacer member 1b may be made of metal or synthetic resin.

The above-mentioned opening 3 is formed in each covering material 1a, and this opening 3
is closed by a transparent sheet material 4. Further, a circular hole 5 is formed adjacent to the opening 3. Both wave cover material 1
The opening 3 and the circular hole 5 of a are aligned with each other.

The spacer member lb has a frame shape having an outer frame strip 6 forming sides, and connecting strips 7.8 connecting the sides, and connecting strips 7 connecting the long sides. A flat space 10 having a brushed square shape is formed between the short side 6 and one short side 6.

The rotary recording medium sheet 2 has a disk shape, and as shown in FIG. 3, a connecting portion 11 connected to an external rotational drive source is attached to the center of rotation. Connecting part 11
is constituted by a disk having a non-circular hole 12, into which a rotational drive shaft (not shown) is fitted.

The rotary recording medium sheet 2 is in this embodiment an optical record of information.

To assemble the members shown in FIG. 2 integrally as shown in FIG. 1, with the recording medium sheet 2 inserted into the space 10 of the spacer member 1b,
．． Coating layers 1a and Ia are applied to both sides of the spacer 8, and when the spacer member and the sheathing material are made of synthetic resin, the coating layers 1a and 1a are applied using an adhesive or heat-sealing coating.

In the assembled state shown in FIG. 1, the connecting portion 11 of the recording medium sheet 2 is tightly fitted into the circular hole 5 and can slide and rotate freely within the circular hole 1. The connecting portion 11 and the covering material 1a are The dimensions are determined so that the surfaces are coplanar and clearly continuous. Further, the surface of the recording medium sheet 20 is slidably in contact with the inner surface of the covering material 1a.

Thus, the recording medium sheet 2 is stored in the card body l with a part of its surface visible from the outside through the transparent sheet 4 of the opening 3, and is rotated by the engagement of the connecting part 11 in the circular hole 5. Become free. Since the opening 3 is a long hole extending in the radial direction of the recording medium sheet 20, different radial band-shaped portions of the recording medium sheet 2 are sequentially exposed to the outside through the opening 3 as the sheet 20 rotates.

This card has the above-mentioned configuration, and its outer edge is completely sealed, and the sliding contact between the circular hole 5 and the connecting part 11 is also completely sealed, and in some cases, the internal space is filled with an inert gas. is included. Therefore, the internal rotary recording medium sheet 2 is protected against outside air, dust, etc.

When the inside of the card is filled with inert gas, the initial state is preserved for a long time without any chemical change even if the recording medium sheet 2 is left bare. It becomes possible to use tellurium and other substances in recording medium sheets. On the other hand, when the recording medium sheet is exposed to the outside air, in principle, a transparent layer is applied to the recording medium itself to eliminate the influence of dust by placing the attached μs dust out of the focus of the optical lens. It is. On the other hand, since the transparent layer applied to the recording medium is a layer of glass or synthetic resin with low optical distortion of 1 mm to several meters, there is a problem that the thickness of the recording medium becomes very large. requires advanced technology, and the presence of some optical distortion is unavoidable, resulting in errors in recorded data. However, if there is a recording medium in an inert gas inside the node, no chemical change will occur, so it may not be necessary to provide one transparent layer, or even if one is provided, the seal may break and peel. 0.31tm to 1[
) The recording medium does not become thick because the thickness is only about the same size as a stick.

In order to completely prevent leakage of the inert gas inside the card, instead of adopting the above-mentioned structure in which the connecting portion 11 is tightly and slidably fitted into the circular hole 5, a completely sealed structure shown in FIG. 4A is adopted. Good. In the same figure, a connecting part 11 fixed to the center of the rotary recording medium sheet 2 projects inside a frame member 14 that forms a circular hole 5 in the covering material 1a, and is entirely fixed to the covering material 1a. An annular groove 15 is formed on the annular inner surface. An annular groove 17 having a small annular groove 16 inside is provided on the outer periphery of the bent protruding portion 11a of the connecting portion 11.
A frame member 14 is inserted into the annular groove 17, and a magnetic fluid 18 is filled across the opposing annular grooves 15,16.

The magnetic fluid 18 allows the connecting portion 11 to rotate relative to the frame 14 while sealing the gap between the connecting portion 11 and the frame 14 . Therefore, the inert gas sealed within the card is prevented from leaking to the outside.

FIG. 4B shows another completely sealed structure in which an inert gas is sealed. In the figure, a connecting portion 11 at the center of the recording medium sheet 2 is fitted into a hole at the center of the covering members 1a, Ia, and a magnetic fluid 18' is placed in the gap between them. The connecting portion 11 is made of a magnetic material, and wear-resistant knobs 111), 111) made of a non-magnetic material are attached to the inner side of the coating material 1a, 111) with the recording medium 7-to 2 sandwiched between the connecting portions 11. Further, a permanent magnet material 19 is interposed around the periphery of both the coverings 81a, 1a to seal the periphery, and an inert gas is sealed inside the card.

The recording medium sheet 2 is, for example, as shown in FIG. 12
It can be constructed by sequentially laminating b1 vapor-deposited recording material layer 2C1 protective layer 2d.

This card is suitable for use in computer game program cards that require a large storage capacity, hospital medical record cards, etc.;
(not shown) are adjacent to each other, and the external drive shaft is connected to the non-circular hole 12.
The recording IJ sheet 2 is rotated.

As a result, optical recording is made on the recording sheet 2. Further, when reading the recording rod sheet 2, the recording medium sheet 2 is similarly rotated and the reading is performed by a reading head using a laser beam or the like through the transparent sheet 4 of the opening 3.

In the card described above, since the rotary recording medium sheet 2 is used, the fitting between the connecting portion and the circular hole that receives it can be maintained with high accuracy, and the joining accuracy between the external drive source and the connecting portion can be improved. By maintaining this, it is possible to increase the reproducibility of the rotation trajectory of one recording medium sheet, and therefore it is possible to increase the recording density, and since it is a rotary type, it is possible to increase the storage capacity. . In this way, it has a rotating recording medium (although, as a whole, it can be made to have the same form and dimensions as a normal card (for example, Q, 8 mm thick), so it can be easily carried, stored, etc. It can be conveniently used.
