It is configured so that it can be pressed against the surface and that the contact provided on the contact guide can electrically press-contact with the circuit terminal on the IC card surface.

[Industrial applications]

The present invention is used to read data from an IC card
IC card reader / writer

The IC card has a plurality of circuit terminals for reading data arranged in parallel in a plane on the insertion side, for example, in eight rows. On the IC card reader / writer side, contacts that can be electrically connected to the circuit terminals are rotated. It is provided on the contact guide.

This contact guide is pivotally supported on the base end side and has a free end on the tip end side, and the contacts are provided on the free end side so as to face the circuit terminals. The contact can be electrically connected to the circuit terminal through the lock lever only when the IC card is set in a predetermined position, and the contact to the IC card is inserted in the process of inserting or removing the IC card. The pressure contact of can be released.

[Conventional technology]

Conventionally, the contacts in the IC card reader / writer used to read the data recorded in the IC card are
During the process of inserting or removing the IC card to a predetermined position, the IC card surface was always elastically pressed and contacted.

For this reason, the above contact to the circuit terminal of the IC card repeats unnecessary pressing contact except at the time of necessary electrical connection, resulting in unnecessary wear. In addition, the load cannot be reduced when inserting or removing the IC card.

On the other hand, the circuit terminals formed on the IC card are generally very narrow, such as 1 mm, and are arranged in parallel at intervals of 8 rows. It is formed with a leaf spring member. The leaf spring member usually has one end fixed to a fixing member, and the contact is formed at the free end of the other end. The contact side is elastically biased in the contact direction. If the contact point relies on the elasticity of only the leaf spring member, a sufficient contact pressure cannot be obtained because the width of the leaf spring member itself is narrow and elongated.

Therefore, this tends to impair the reliability of the electrical contact of the contacts.

[Problems to be solved by the device]

As described in the related art, in the configuration in which the contacts provided in the IC card reader / writer rely on the elasticity of only the leaf spring member, especially in the case of contacts that are miniaturized for IC cards, sufficient contact for durability is also achieved. There was a problem that pressure could not be obtained.

According to the present invention, a contact for electrically pressurizing contact with a circuit terminal of an IC card is provided on the free end side of a contact guide capable of forcibly pressing, and the free end of the contact guide is forcibly inserted with the insertion of the IC card. It is an object of the present invention to provide an IC card reader / writer in which the contact pressure of the contacts is increased by lowering the contact pressure.

[Means for solving the problem]

In order to achieve the above object, the IC card reader / writer according to the present invention has a contact provided at a position where the IC card is set by insertion, formed of a conductive leaf spring member on the lower surface of the contact guide on the free end side. Provided while maintaining elasticity.

Next, the base end side of the contact guide is pivotally supported, the lock lever is further opposed to the free end side of the contact guide and pivotally supported, and the lock lever is rotated by the pushing force of the IC card, and By the above rotation of the lock lever, the free end side of the contact guide can be lowered so that the contact pressure of the contact can be increased.

[Action]

The contact provided at the free end of the rotating contact guide is
Since the circuit terminal of the IC card is forcibly pressed into contact with the circuit terminal of the IC card through the lock lever which is rotated by the pressing force due to the insertion of the card, the electric contact connection of the contact to the circuit terminal can be reliably performed.

Further, the IC card inserted in the set position is stably locked by the rotation contact force of the lock lever as well as the contact force of the contact of the lock lever, and is not retracted from the inserted set position by an excessive amount. It

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view of a main part of an IC card reader / writer, and FIG. 2 is an operation explanatory view of the main part when the IC card shown in FIG. 1 is inserted and set at a predetermined position.

In FIG. 1, a set position 3 where the IC card 2 is set by insertion is provided in the IC card reader / writer 1, and a contact guide 5 provided with a contact 4 facing the set position 3.
Is provided.

The contacts 4 are formed at the tip of a conductive leaf spring member 4a. In the case of this embodiment, the contacts 4 are located at positions that are forward and backward with respect to the insertion direction of the IC card 2 (horizontal direction in the drawing). It is provided on the lower surface of the guide 5. The base end side of the leaf spring member 4a having the contact 4 at the free tip is fixed to the lower surface of the contact guide 5 via the insulating member 4b as described above.

The contact guide 5 has a free end 5a on the front end side and a base end.
The 5b side is pivotally supported 6 on the IC card reader / writer 1 side.

In the above description, the contact guide 5 has an appropriate width corresponding to the width direction of the IC card 2, and the contact 4 on the lower surface and the circuit terminal 2a provided on the insertion side on the upper surface of the IC card 2 respectively. It is provided at the corresponding position.

Therefore, the circuit terminals 2a provided on the upper surface of the IC card 2 are composed of a plurality of conductive members having a width of, for example, 1 mm and an appropriate length and arranged laterally at intervals such as eight circuits. The contacts 4 arranged in parallel and facing the circuit terminals 2a are divided into front and rear rows in the case of this embodiment, and are provided by a corresponding number of elongated leaf spring members 4a in the lateral direction.

Although not shown in the drawing, the contact guide 5
A return spring member is internally mounted on the shaft support 6 portion, and the free end 5a side of the contact guide 5 is always elastically biased upward by the elasticity of this spring member. Therefore, normally, the contact 4 is set at the setting position 3 of the IC card 1.
The contact lever 5 is on standby at a position lifted up from above, and the upward rotation of the contact guide 5 is restricted by the lock lever 7.

The lock lever 7 is provided so as to face the free end 5a of the contact guide 5 and is formed in a herringbone shape so as to be able to come into contact with the tip of the IC card 2 to be inserted, and on the IC card reader / writer 1 side. It is pivotally supported 8.

A card stopper 9 is provided at the insertion end of the set position 3 into which the IC card 2 is inserted.

Next, a state when the IC card 2 is inserted and set in a predetermined position will be described with reference to FIG.

In the figure, the IC card 2 inserted in the setting position 3
Is pushed in until the tip comes into contact with the card stopper 9, the lower portion of the lock lever 7 provided in front of the card stopper 9 is pressed by the tip of the IC card 2, and the lock lever 7 is pushed. Is rotated in the direction of arrow A for the thicker part.

When the lock lever 7 rotates in the direction of arrow A, the free end 5a side of the contact guide 5 that is in contact with the upper portion of the lock lever 7 is pushed down, and the contact guide 5 rotates in the direction of arrow B. Therefore, by this operation, the contact 4 provided on the lower surface of the contact guide 5 drops to the surface of the circuit terminal 2a of the IC card 2 inserted in the set position 3 and is forcibly pressed and contacted.

In this case, the contact pressure of the contact point 4 is obtained by the elasticity of the leaf spring member 4a of the contact point 4.
Is pressed downward by the contact guide 5, so that the contact pressure of the contact 4 can be increased.

When the lock lever 7 rotates in the direction of arrow A, the free end 5a side of the contact guide 5 is lowered as described above. Therefore, the IC lever 2 of the IC card 2 is moved by the lock lever 7 together with the lowered free end 5a. The tip side is pressedly locked to the base surface at the setting position 3.

The above-mentioned lock of the IC card 2 is released by pulling out the IC card 2 in the opposite direction to the insertion, but the lock pressure is within a range in which the IC card 2 can be pulled out.

Also, when the IC card 2 is retracted from the contact position with the lock lever 7, the elasticity of the leaf spring member 4a having the contact 4 and
The restoring force of the contact guide 5 causes the contact 4 and the lock lever 7 to return to the positions shown in FIG. Therefore, when the tip of the IC card 2 separates from the lock lever 7, the subsequent withdrawal of the IC card 2 can be smoothly performed without the contact resistance of the contacts 4 and the like.

In the above description, the locking of the IC card 2 by the lock lever 7 is not shown, but for example, a recess is provided in the set position 3 surface of the portion pressed by the lock lever 7 so that the tip side of the IC card 2 is locked by the lock lever 7. The above-mentioned locked state can be further enhanced by elastically pressing and locking it so as to bend in the recess.

[Effect of device]

Since the present invention is configured as described above, the leaf spring having the contact point in the electrical contact connection between the contact point in the IC card reader / writer and the circuit terminal of the IC card set by being inserted in the IC card reader / writer. Even if the elastic force of the member is weak, the contact guide can be rotated and pressed stably and reliably.

Therefore, the reliability of the electrical contact of the contacts provided on the small leaf spring member can be remarkably improved.

In addition, the interposition of the lock lever allows the IC card inserted in the set position to be locked at the same time.
