Abstract

PROBLEM TO BE SOLVED: To attain the smooth insertion of an IC card even at the time of inserting the IC card in an oblique direction. SOLUTION: An arm part 11b of a contact terminal 11 brought into contact with the side face of an IC card C is bent like a crank from the base terminal part so as to be formed of almost the same plane as an inner deep face 4a of a guide groove 4 of a guide frame 3 and exposed from a window hole 4b. Thus, even at the time of inserting the IC card in an oblique direction, the corner part can be prevented from being hooked by the window hole 4b, and the insertion of the IC card can be prevented from being interrupted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card loading device, and more particularly, to an IC card loading device characterized by the shape of a contact terminal that contacts a side surface of the IC card.

[0002]

2. Description of the Related Art In an IC card loading apparatus, a contact is made with an IC card inserted from an insertion slot and loaded at a predetermined position to read out data stored therein or to store new data. Usually, a ground contact terminal is provided for contacting a metal portion provided on the surface or side surface of the IC card, and by setting the IC card to the ground potential, damage to the IC card due to static electricity and malfunction of the electronic device body can be prevented. It is configured to prevent.

A grounding terminal of this type projects from a window provided in an insulating frame into an IC card insertion path so that a tip portion bent in a semicircular shape contacts a metal portion of the IC card. When the IC card is inserted diagonally, the corners of the tip are caught on the steps of the frame holding the base of the grounding terminal, and the insertion is smooth. Inconvenience that it cannot be performed occurs.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem.
An object of the present invention is to provide an IC card loading device provided with a new contact terminal that does not catch a corner of the IC card.

[0005]

That is, in order to achieve the above object, the present invention provides an arrangement in which a terminal that comes into contact with the side surface of an IC card is exposed from a window hole formed in an inner surface of a card guide groove. In the installed IC card loading device, the arm portion following the distal end portion of the terminal exposed from the window hole is formed by bending from the base end portion so as to be substantially flush with the inner surface of the card guide groove. It is intended to be.

[0006]

According to this structure, even when the IC card is inserted obliquely, the corners of the IC card move over the arms of the contact terminals which are substantially flush with the inner surface of the guide groove.
The window can be passed without hindering insertion.

[0007]

Embodiments of the present invention will be described below. The drawings show an embodiment of the present invention.

First, the entire contents of an IC card loading apparatus will be described with reference to FIG. 3. In the figure, reference numeral 1 denotes an apparatus main body fixed at a predetermined position such as a circuit board 2 or the like. It is constituted by guide frames 3, 3 made of a pair of left and right resin materials provided with grooves 4, 4, and a top plate 6 fixed to the upper surfaces thereof so as to straddle these guide frames 3, 3. An ejector 7 for discharging the IC card C is slidably attached to one side of the main body 1.

Reference numeral 10 in the figure denotes a contact terminal unit for contacting a metal portion provided on the surface or the side surface of the IC card C and grounding it. The contact terminal unit 10 of
As shown in FIGS. 1 and 2, the first contact terminal 11 whose tip 11 a is exposed from the inner inner surface 4 a of the guide groove 4 and slides on the metal part on the side surface of the IC card C, and the lower surface of the guide groove 4 And a second contact terminal 15 which is exposed upwardly from and comes into sliding contact with a metal portion provided on the surface of the IC card C.

The above-mentioned first contact terminal 11 is formed so that its arm 11b fills a window 4b provided in the inner inner surface 4a of the guide groove 4 so as to be substantially flush with the inner inner surface 4a. A crank 13 is formed by bending the rising piece 14, and a stay 13 is formed on the crank portion 12 so as to connect the arm 11 b and the rising piece 13 in a direction substantially orthogonal to these surfaces. And is configured to increase the rigidity of this portion.

On the other hand, the second contact terminal 15 is formed by bending the tip of the extension piece 16 extending from the attachment piece 17 to the guide frame 3. The above-mentioned rising piece 14 is bent upward.

In the guide frame 3 thus configured, a first groove formed in the guide groove 4 in a crank shape is formed.
Since the arm 11b of the contact terminal 11 is mounted so as to cover the window 4b and to be substantially flush with the inner back surface 4a of the guide groove 4, the IC card C is inserted slightly obliquely. Even in such a case, the corner moved along the inner back surface 4a of the guide groove 4 slides on the first contact terminal 11 as it is, and is loaded without being caught in the window 4b.

Moreover, the crank portion 12 of the first contact terminal
Since the stay 13 is bent so as to connect the arm 11b and the rising piece 14 so as to connect the arm 11b and the rising piece 14, a large bending of the arm 11b is suppressed even when pressed by the corner. Further, the pressing force of the IC card C applied here causes an upward force to act on the second contact terminal 15 via the rising piece 14 to appropriately press the surface of the IC card C to insert the card. It works to suppress blurring.

Although the present invention has been described based on an example of a contact terminal for grounding an IC card, the present invention is also applied to a detection terminal for detecting whether or not a card is inserted. Can be applied.

[0015]

As described above, according to the present invention, since the arm portion of the terminal exposed from the window hole in the inner surface of the card guide groove is formed so as to be substantially flush with the inner surface. ,
Even if the card is inserted diagonally, the corner at the tip automatically comes out of the window hole along the arm, so that smooth insertion can always be ensured.

Further, since the stay is bent at the bent portion to increase the rigidity of this portion, the arm portion can be displaced substantially parallel to the inner back surface even when pressed by the corner of the card. As a result, the corner of the leading end of the card can be separated from the window without any trouble.
