JPH04205584A - Inserting/ejecting mechanism for ic card - Google Patents

Abstract

PURPOSE:To facilitate the insertion/ejection of an IC card and moreover, to safely protect the IC card after loading by providing a lug protruded so as to be abutted on an IC card inserting inner end at the supporting point side end of a cover and a projection for cam protruded so that a flank is abutted on an IC card inserting destination end at the open end side of the cover. CONSTITUTION:An IC card 6 is flatly placed on an IC card placing face 2 and the cover 5 is closed in the case of inserting/ejecting the IC card by the inserting/ejecting mechanism of the IC card. Then, the flank 7A of a projection for cam 7 of the cover 5 comes into contact with the read end of the IC card 6 and the IC card 6 is pushed in a connector direction simultaneously with a cover closing operation. Besides, when the cover 5 is sealed hermetically, the IC card 6 is covered by the cover 5 and protected from an external part. Next, when the cap body 5 is opened, the lug 5A is in contact with the insertion inner end 6A of the IC card 6 and pushed it out and releases the engagement with a connector 3. Accordingly, when the cover 5 is opened completely, the IC card 6 can be taken out freely.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a mechanism for attaching and detaching an IC card such as a memory card in a computer or the like.

[Conventional technology]

BACKGROUND OF THE INVENTION It is very common to use external recording media such as memory cards as auxiliary storage for computers and the like.

Many of these memory cards are designed to be inserted and removed directly into a connector provided on the computer body, but there are also known cards that are inserted and removed using an eject mechanism A as shown in Figure 5. ing.

[Problems with conventional technology]

However, as the storage capacity of the memory card increases, the number of connector contacts also increases, and the force required for insertion and removal also increases. Therefore, it is very difficult to insert and remove the connector directly by hand, and even if an eject mechanism is used, there is a drawback that the link mechanism must be complicated and large in order to improve the insertion and removal force.

In addition, if the memory card is inserted or removed by hand, it is necessary to leave a part of the memory card B protruding from the main body C as a clue, as shown in Figure 6, so that it may not be exposed to shocks from other objects or static electricity. It had the disadvantage that it could not effectively protect against failures.

[Problem to be solved by the invention]

In view of the above-mentioned problems, this invention provides a compact IC card insertion/removal mechanism that allows easy insertion and removal of an IC card even when a large insertion/extraction force is required, and that can safely protect the IC card after insertion. It was made for the purpose of providing.

[Technology that led to solving the problem]

That is, the IC card attachment/detachment mechanism of the present invention includes a smooth IC card placement surface, an IC card connector opening parallel to the placement surface, and an IC card placement surface using the connector position as a fulcrum. a lid body pivotably supported to be openable and closable covering the entire surface thereof; a claw body protruding from the fulcrum side end of the lid body so as to be able to come into contact with the inner end of the IC card insertion; It is characterized by comprising a cam protrusion protruding from the open end side so that its side surface can come into contact with the IC card insertion tip.

〔Example〕

Next, the present invention will be explained in detail.

FIG. 1 is a sectional view of an embodiment of the present invention, and FIGS. 2 and 3 are sectional views showing how the embodiment is used.

The IC card attachment/detachment mechanism 1 of the present invention is a computer D.
A smooth IC card placement surface 2 provided on the surface of the main body, an IC card connector 3 erected with an opening parallel to this placement surface 2 (arrow X), and this connector. A lid body 5 is pivotally supported so as to be openable and closable while covering the entire surface of the IC card mounting surface 2 with the position as a fulcrum 4, and the end of the lid body 5 on the side of the fulcrum 4 is capable of abutting the insertion rear end 6A of the IC card 6. It is composed of a protruding claw body 5A and a cam protrusion 7 protruding from the open end side 5B of the lid body 5 so that the side surface 7A can come into contact with it.

In the above embodiment, the lid body 5, the claw body 5A, and the cam protrusion 7 may be integrally molded, or may be formed by bonding blocks of respective shapes.

In addition, as shown in FIG. 4, a structure may be adopted in which an inoecta acnotimment 8 is inserted between the claw body 5A and the IC card 6.

In this case, it is convenient because it can prevent a large local stress from being applied to the IC card 6.

Further, although not shown in the drawings, a bearing may be constructed such that the lid 5 will come off the fulcrum 4 when a strong pull-out moment is applied to the claw 5A, thereby protecting the IC card 6 and the claw 5A.

[Effect]

To attach and detach an IC card using the IC card attaching and detaching mechanism 1 of the present invention, as shown in FIG. 2, the IC card 6 is placed flat on the IC card placement surface 2, and the lid 5 is closed.

At this time, the side surface 7A of the cam projection 7 of the lid body 5 comes into contact with the rear end of the IC card 6, and simultaneously with the lid closing operation, the IC card 6 is pushed toward the connector.

Furthermore, if the lid 5 is completely sealed, the IC card 6 is completely covered by the lid 5 and protected from the outside as shown in FIG.

Next, when the lid body 5 is opened, as shown in FIG. 3, the claw body 5A comes into contact with the insertion rear end 6A of the IC card 6 and is pushed out as a result of the opening operation, as shown in FIG. Therefore, if the lid body 5 is completely opened, the IC card 6 can be freely taken out.

〔effect〕

As explained above, in this invention, the IC is connected simultaneously with opening and closing of the lid.
The card is removable and easy to operate, and when the lid is closed, the IC card is completely protected by the lid. Furthermore, when an IC card is removed, it is pushed out with a strong force by the claw body that comes into contact with the IC card at the same time as the lid is opened, so even IC cards with large storage capacity can be safely inserted and removed. has.
