Description

[Detailed description of the invention] [, Industrial application field] This invention relates to the structure of an IC card [Summary of the invention] The present invention is based on the data input into the IC2.

For IC cards that are capable of holding and reading private output, there is a mechanism for replacing batteries for data retention, a mechanism for preventing data from being sworn in, a shutter while protecting input/output terminals, an automatic shutter opening/closing mechanism using an external connector, and a mechanism for automatically opening and closing input/output terminals. IC with structure to prevent incorrect insertion when following external connector
0, which is the structure of the card. [Object of the Invention] The present invention can easily eliminate battery damage and prevent data from being written erroneously. or.

The input/output terminals are equipped with a mechanically protected shutter, which protects the external connector.
Automatically opens and closes when removed. When connecting the input/output terminal to an external connector, if you accidentally insert the front and back sides of the card.

Is there a structure that prevents incorrect insertion so that it is not completely inserted into the housing and can be completely inserted only when inserted correctly? Wait for the IC card to be presented.

[Effect]

According to the above configuration of the present invention, when an IC card is used.

(When inserting the card into the connector of an external device).

The shutter is opened by a shutter opening protrusion provided on the card insertion guide of the connector, and is closed by a shutter closing claw provided on the connector at the end of use (when removing the card). In addition, the guide groove provided on the side of the card frame for the shutter opening/closing protrusion and claw on the connector side is off center of gravity relative to the thickness, which makes it difficult to insert the IC card from the front to the back, or from the opposite direction when inserted. The shutter opening protrusion on the connector side hits the card frame to prevent card errors.

[Examples of actual inventions]

The following is an example of this invention, FJ', based on the drawings. ○ Is Figure 1 the appearance of an IC card manufactured according to this invention?
FIG. 2 is an exploded perspective view of this IC card. The main body 1 of this IC card is based on a two-shaped frame 2 shown in FIG.
and a pack panel 8 serving as a surface material are laminated to form a sentence structure.

Inside the main body 1, a circuit board 5 is adhered with a two-sided adhesive film 9, with positioning dowels 17 formed on the resin frame 2 at the bottom of the unit as a reference, and a circuit board 5 is bonded with a two-sided adhesive film 9. The circuit board 6, to which a film separator 10, a metal shutter plate 4, and a merged resin film spacer 11 for securing movement space for the shutter plate 4 are polymerized and bonded, has predetermined wiring and Input/output terminal pattern 18. Contact pattern 19 for data penetration prevention switch 6. End face through holes 20.27 for power supply contacts are provided, and IC chips and chip components such as capacitors and diodes are mounted therein.

Note that the frame 2 is provided with a through hole 21 that serves as an escape for the IC chip and chip components protruding onto the circuit board 5, and is further provided with a data tampering prevention switch set portion 22. Battery holder set part 23. Spring contact portions 24 and 25 are formed for power supply.

The writing prevention switch set section 22 includes a digging prevention switch 6 and a writing Di contact spring 1.
2 is connected to the data writing prevention contact pattern 19 of the 1 circuit board 5. By sliding the loading switch 6, the arm point 412 slides to switch between writing and storing prevention states.

The power supply contact spring set portions 24, 25 include battery contact springs A13. Battery contact spring B14 is assembled,
The four-way contact spring A15 contacts the negative lead plate 26 of the battery holder 5, and! The battery contact springs B14 are in direct contact with the positive side of the battery, and are connected to the i-plane square x-hole 2 of the circuit board 3, respectively.
Provide power through 0.27.

It was a cabinet. The battery holder 5 is integrally molded with the negative lead plate 26, and is attached to the frame 2 by an elastic claw 28, and is pulled out using a battery holder drawer hook 29 when replacing the battery. A protrusion 60 is provided on one side to prevent reverse insertion when the battery holder is set.

17t, Figure 3 shows the front panel 7 and back panel 8.

The refilm 33 is stamped with adhesive 52 on a metal dry plate (stainless steel, etc.) of about 100 mL.
and an insulating coat 61 at the place in contact with the battery holder 5.
was applied and cents were placed in frame 2. The metal surfaces of the welded parts of the shielding coil springs A, B, (15, 16) between the front panel, bank panel 8, and circuit board 3 are exposed, and the other parts are covered with a film-like adhesive 34. has been done. (See Figure 2.) Figures 4 and 5 show the key connector 34 with shutter opening/closing mechanism. When inserted, a connector 34 is provided in a guide groove 36 for opening and closing the shutter.
The shutter opening protrusion 35 enters and hits the opening/closing protrusion 52 of the shutter plate 4, and by further insertion, the shutter plate 4 is opened. Mano.

After the IC card is finished, the action of pulling out the IC card is confusing.
The shutter plate 4v opening/closing protrusion 52 is caught by the shutter closing claw 56 provided on the connector 34, and the shutter plate 4 is closed. As a result of further pulling, the shutter closing claw 56 climbs over the opening/closing protrusion 52 and the IC card with the shutter closed comes out. Also, the guide groove for opening/closing the shutter on the IC card side is offset from the center relative to the card thickness (see Figure 6), so the shutter opening protrusion 35 of the connector 34 will not fit.

It has a structure that prevents incorrect card insertion.

According to this invention! Crossing the pond is easy.

It prevents reverse insertion of the battery case and incorrect insertion of the IC/J-card into the external device, and secures input/output terminals.
Since it is also equipped with a data write prevention switch that prevents double writing, it is possible to provide an easy-to-use IC card that is highly safe for data storage.
