Abstract

PURPOSE:To prevent the destruction of information due to the static electricity as well as the adverse insertion of a cassette, by adding an external connector to the inside of a rotatable cover and a metallic bar for grounding to an adverse insertion preventing groove at the outside of a cassette. CONSTITUTION:When a cassette 1 is loaded, a pawl 6 is pushed by a cam of a magnetic bubble device. Then a rotatable cover 3 is turned and opened horizontally, and the magnetic bubble device is electrically connected to the cassette 1 via an external connector 7 provided inside the cover 3. While a groove 4 is formed at the side part of the cassette 1, and a metallic bar for grounding 5 is provided at the bottom of the groove 4. If the cassette 1 is loaded upside down, the insertion of the cassette 1 is prevented by a projected streak corresponding to the groove 4. This prevents the destruction of information due to the static electricity produced by a touch of a human body. At the same time, the adverse insertion of the cassette can also be prevented.

ト構成にしたごとによる特有の問題がある。(t+) Prior art and its problems Recently, magnetic baffle devices have been constructed into cassettes, but since the current handled by the magnetic bubble chip 2 is extremely small, the magnetic hub cassette 1 is used in peripheral circuits. If there is even a slight loss of lr5 in the connector connected to the external circuit, the specified current will not be able to flow. Furthermore, if the human body comes into direct contact with the connector, there is a risk that the information in the magnetic hub will be destroyed by static electricity. Furthermore, there are problems unique to each magnetic bubble device configured as a cassette, such as grounding of the magnetic hub, prevention of reverse insertion of the magnetic bubble cassette, and write protection.

付勢している。Figure 4 shows the opening/closing operation of the lid 3. (A) shows the state before the lid is opened, (1:+) shows the state when the lid is open, and (C) shows the relationship between the lid and the mating connector. FIG. The lid 3 has two claws 6, G41-, on its upper end;
．． 6 is formed with a sulin 18 that opens downward as shown in Fig. 0 (1 (c)), and its opening width is smaller than the inner part. The diameter of the shaft 9 fixed to the insert and exposed to the slot 7110 is smaller than the inner diameter of the deep part of the slot 18 and slightly larger than the opening width. Therefore, as shown in (c), the opening of the slit 1 is placed on the shaft 9 and pressed in the direction of arrow a2, or the shaft 9 is press-fitted into the slit 8, and the lid 3 is then easily removed. This is not the case.A torsion spring (not shown) is wound around the shaft 9 (which always urges the lid 3 to close 11!i).

１４と結合する。In this state, the top surface of the lid 3 is substantially flush with the bottom surface of the groove 11. Reference numeral 12 is a holder into which a magnetic hub socket is inserted, and a protrusion 13.13 is provided on the inner surface of the ceiling at a position corresponding to the clearance groove 11.11. Then, as shown in (a), when the magnetic bubble case 1 is inserted in the direction of arrow a1 toward the mating connector 14 provided deep inside the boulder 12, the claw 6.6 at the top end of the lid 3 is inserted into the ceiling. Convex ■3.

入口への１Φ入も不可能なため、一層有効である。Note that if the magnetic head is inserted in the opposite direction, the magnetic head will hit against the protrusion I3 and will not be able to be inserted, so the protrusion J3 can also serve as a function to prevent reverse insertion. In particular, the protrusion 13 is the number of people with 12 boulders [21
It is even more effective if the magnetic hub case 1~ is extended to the holder because it is impossible to insert the 1Φ into the entrance of the holder.

。As shown in FIG. 4 (c), on the inner walls on both sides of the bolt 12,
A protrusion 15.15 is provided, and when inserting the magnetic hub case 1, this protrusion 15.15 fits into the M4 of the magnetic hub case, thereby preventing reverse insertion of the magnetic bubble force. Prevented. The grooves 4 are located in vertically asymmetrical positions (when the magnetic hub cassette 1- is turned upside down and inserted into the boulder 12, the convex strip 15.15 can be inserted into the reverse insertion prevention groove 4 of the magnetic hub cassette 15). This ridge 15.15 and the groove 4 of the magnetic hub holder also serve as a guide when inserting the magnetic holder 1 into the bolt, and also serve as a mutual positioning function.

As shown in FIG. 3(c), a groove 16 is provided in a direction perpendicular to the insertion direction, and a scoop 17 is fitted into the groove 16. This slide piece 17 is shorter than the groove 16, and one end of the groove 16 is open to the front of the magnetic hub case 1. Therefore, when the slide piece 17 is retracted to the illustrated position,
The recess 16u created by the retreat of the slide piece 17 of i@16 communicates with the opening L118. - force holder 12
On the side, a shielding plate 20 fixed to the bottle 19 is provided at a position in front of the opening 18, and a light emitting element 21 and a light receiving element 22 are provided on both sides of the shielding plate 20.

1118 and the fourth part IGu6 enter and bin I9 does not move. However, when the stripe 41 piece 17 slides in the direction of the arrow a3 and fills the four parts 16u on the open 1-118 side, the side of the slide 'J' 717 hits the bottle 19 and the bottle 11] moves in the direction of the arrow a3. Since it moves in the a4 direction and the shielding plate 20 blocks the space between the light emitting element 21 and the light receiving element 22, it becomes impossible to receive light.

Therefore, except when the magnetic bubble cassette is combined with the 21 connector on the bolt side, the connector on the magnetic bubble cassette is closed with a lid, and the information on the magnetic bubble cassette may be destroyed by contact with the human body, or it may become dusty. This prevents it from getting dirty and causing problems with electrical connections. Further, on the outer surface of the magnetic hub case 1-, a groove is provided to prevent reverse insertion, and a grounding metal is provided in the groove to prevent connection to the ground circuit of the magnetic bubble device. As a result, the groove for preventing reverse insertion (reverse insertion is prevented, and the grounding metal piece is provided at the bottom of the groove for preventing reverse insertion and is retracted), so that the human body does not come into contact with the earthing metal piece.・
) will be prevented.

したことを牛へ徴とする磁気ハブルカセソ１−０[Scope of Claims] In a magnetic hub case 1 in which a magnetic bubble device consisting of a magnetic baffle chip, a drive coil, a bias magnet, etc. is built into an insulating case, a magnetic hub case that rotates around a support shaft is mounted on the end face of a magnetic hub case. At the same time, a connector for electrically connecting the magnetic bubble device to the external point is installed on the inside of the prototype, and a connector to prevent reverse insertion is installed on the outside of the magnetic hub case No. 1. In addition to installing a groove for grounding, a grounding metal is placed in the groove to signal to the cow that it is connected to the ground circuit of the magnetic pull device.
