[Problems to be solved by the device]

 In the above-mentioned conventional IC card holder 11, since the lateral members 14, 15 and the eject plate 18 are made of sheet metal, they can be made thinner than when they are made of resin. However, the following problems occur.

That is, when foreign matter or cards of different types are forcibly inserted into the IC card holder 11, the contact pins 26, 26, ... May be bent and deformed. However, since the horizontal member 15 and the eject plate 18 made of sheet metal are located below the contact pins 26, 26, ... Of the connector 25, when the contact pins 26, 26 ,. The lateral members 15 and the eject plate 18 may come into contact with the contact pins 26, 26, ... And cause defects such as shorts.

Therefore, in the conventional IC card holder 11, the insulating sheet 30 is attached to the upper surface of the eject plate 18 to prevent the occurrence of a short circuit or the like. As described above, when the IC card is ejected, it moves upward as shown in FIG. 6, and the insulating sheet 30 also moves with it.

Therefore, in the eject state of FIG. 6, the insulating sheet 30 does not exist immediately below the contact pins 26, 26, ..., Therefore, the contact pins 26, 26 ,. Then, the contact pins 26, 26, ... Directly contact the metal surfaces of the lateral member 15, the eject plate 18, etc. and cause a defect such as a short circuit.

In view of the above point, the present invention has a problem such as a short circuit between the contact pin and the sheet metal horizontal member or the eject plate even when the contact pin is deformed in the IC card eject state. It is an object of the present invention to provide an IC card holder that is prevented from inviting.

[0020]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the IC card holder according to the present invention is assembled in a substantially frame shape by bridging horizontal members made of sheet metal on the front end side and the rear end side of the left and right vertical members, respectively. An eject plate made of sheet metal that constitutes the operating end of the eject mechanism is arranged so as to slide in the front-rear direction on the rear end side horizontal member, and an IC card is mounted on the eject plate and the rear end side lateral member. The insertion part in the card of the contact pin of the connector used for the connection is positioned, and the insulating sheet is attached to the upper surface of the eject plate. In both the mounted state and the ejected state of the IC card, The size of the insulating sheet is set so that the insulating sheet is interposed between the insertion portion of the contact pin in the card and the lateral member. It is characterized in that it is a constant.

[0021]

[Action]

 In the IC card holder according to the present invention having the above-described structure, the insulating sheet attached to the eject plate is set to have a relatively wide width so as to cover the upper surface of the eject plate and stick out from it. Thus, in both the IC card mounted state and the ejected state, the insulating sheet is interposed between the card pin insertion portion of the contact pin and the lateral member.

Therefore, even if the contact pin is deformed in the IC card eject state, a short circuit or the like is not caused between the contact pin and the sheet metal lateral member or the eject plate. To be done.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of an IC card holder according to the present invention. The IC card holder 10 in the figure is basically the same as the conventional IC card holder 11 shown in FIGS. 3 to 6 except for the insulating sheet 40. Will focus on the differences.

In the IC card holder 10 of this embodiment, the insulating sheet 40 attached to the eject plate 18 is larger than the conventional one. That is, the insulating sheet 40 is set to have a width at least twice as wide as that of the conventional insulating sheet 30 so as to cover substantially the entire upper surface of the eject plate 18 and protrude rearward therefrom. Then, notches 40a, 40a into which the locking rising pieces 18b, 18b provided on the eject plate 18 are inserted are formed near the center of both ends of the insulating sheet 40.

The insulating sheet 40 is made of a polyester film or the like, and the front half thereof is attached to the upper surface of the eject plate 18 with an adhesive, a double-sided tape or the like.

The eject plate 18 may be made of sheet metal like the conventional one, but a resin thin plate spacer or the like is attached to the upper surface of the eject plate 18 made of sheet metal, and the insulating sheet 40 is placed thereon. It is also possible to prevent the rear part (protruding part) of the insulating sheet 40 from rubbing against the lateral member 15 on the rear end side, the intermediate lever 21 of the eject mechanism 20, etc. as much as possible.

Since the insulating sheet 40 is relatively wide as described above, the contact pin of the connector 25 can be used in both the mounted state (FIG. 1) and the ejected state (FIG. 2) of the IC card 50. The insulating sheet 40 is interposed between the in-card insertion portion 26 a of the card 26 and the lateral member 15.

Therefore, even if the contact pin 26 is deformed in the IC card eject state, a short circuit or the like is caused between the contact pin 26 and the lateral member 15 made of sheet metal, the eject plate 18, or the like. I will not do anything.

Further, since the notch portions 40a, 40a into which the locking rising pieces 18b, 18b of the eject plate 18 are inserted are formed at both ends of the insulating sheet 40, the insulating sheet 40 is ejected from the eject plate 18 by the cutout portions 40a, 40a. Positioning becomes easy when attaching the sheet to the sheet, workability is improved, and the position of the insulating sheet 40 with respect to the eject plate 18 can be accurately set.
