Description: BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a portable terminal device in which electronic money IC cards memorizing electronic monetary information are inserted, and with which the electronic monetary information is read out and/or write into the cards. Description of Relevant Art As an example of prior arts relating to the present invention, such a terminal device for a IC card was already described, for example in Japanese Utility Model Laying-Open No. Hei 1-144957 (1989) entitled "A Reader and Writer for a IC Card having a door structure". However, in accordance with the terminal device for a IC card of the prior art, only one IC card can be inserted into one card slot opening thereof. Therefore, with such the device, for inserting a plurality of IC cards into it so as to transfer data between them, there is necessity of further providing another card slot opening and another means or structure for establishing electrical connection between the device and the IC card inserted into the another slot opening, separately, thereby causing a drawback of enlarging the size of the device itself. Further, as an another prior art relating to the present invention, in a terminal device described for example in Japanese Patent Laying Open No. Hei 6-20106 (1994) entitled "A Data Transfer System and A Data Transfer Terminal ", there are provided two card slot openings in which two IC cards can be inserted separately. However, in the conventional terminal device, as mentioned in the above, the device itself becomes large in size, due to the increase in the number of the card slots and the interior structures thereof. The terminal device described in the prior art, however, is such a device which is inherently located in front of a store for the purpose of conducting pay on account electronically, therefore there is no consideration about portableness of the device. Further, EP-A-0 696 010 relates to a portable interface for one or more electric smart cards. The interface in one of its embodiments has a slot to receive two cards. Said interface serves to provide a connection between one or more electric smart cards and a card reader for PCMCIA type cards. Further, US-A-5-434-395 describes a transaction device for carrying out transactions between a master card and a slave card. The device has several slots, each of which receives one card. Moreover, as a further prior art relating to the present invention, a portable terminal device also has been known, for example in Japanese Patent Laying-Open No. Hei 9-50497 (1997) entitled "A Transfer Device of Electronic Monetary Information", in which two IC cards are inserted into two card slot openings respectively. In the conventional portable terminal device, the two slot openings for insertion of the IC cards are provided on a front edge portion and a rear edge portion of the device, respectively, and one of the two IC cards is inserted into the front edge slot opening, and the other thereof into the rear edge slot opening. And within the device, those inserted IC cards are inserted and positioned on a same plane with abutting the front edges to each other, thereby reducing the thickness of the device and obtaining superiority in the portableness. However, in general, with the portable terminal device mentioned above in which two IC cards are inserted, it is constructed with an assumption the monetary information of the one of the IC cards are read out and the monetary information which is read out is transferred to the other IC card, and in that case, it has a drawback that the IC card which is inserted into the rear edge slot opening can be easily dropped out from the slot because of small degree of insertion (i.e., it is not deeply inserted into the slot), according to the construction thereof. Further, regarding an operability of the portable device, in particular in insertion of the IC cards, there is no problem for the slot opening which is positioned on the front edge portion of the device, however, since the other slot opening is located on the rear edge portion (reverse side) of the device, the operation of inserting the IC card into the other slot opening is troublesome, and there is problem in the operability of the device. Therefore, in accordance with the present invention, it is an object to dissolve the problems mentioned in the above, in more particular, to provide a portable terminal device for electronic money IC cards, into which at least two electronic money IC cards can be inserted and with which monetary data of them can be transferred to and/or exchanged with each other. Further, especially in accordance with the present invention, it is another object to provide a portable terminal device for electronic money IC cards, the construction of which is suitable for obtaining a small-sized terminal device, and for obtaining the portable terminal device for electronic money IC cards having a superior operability including the insertion of the electronic money IC cards. For accomplishing the object mentioned above, in accordance with the present invention, there is provided a portable terminal device for electronic money IC cards containing monetary data therein as defined in claim 1. The advantageous embodiments are defined in dependent claims 2 and 3.

The main body 10 has a card slot opening 12 into which a plurality of electronic money IC cards (in this embodiment, for instance, three pieces of the IC cards) can be inserted. With such the portable terminal device for electronic money IC cards, into the card slop opening 12 are inserted the plural electronic money IC cards 100, 110 and 120, and thereafter, by pushing the button 82 for checking the remaining money amount, i.e., remaining amount of the electronic money held in the inserted electronic money IC card can be displayed on the display portion 80, so as to be checked or ascertained by a user thereof. The display portion 80 can be constructed, for example a liquid crystal device (LCD). Moreover, for exchanging the display of remaining money amount over those IC cards which are inserted, the check button 82 forthe remaining money amount can be used in common. Namely, the display of the remaining amount is automatically and cyclically exchanged by every push of the check button 82. Alternatively, further other push buttons can be added on the main body 10 of the portable terminal device for that purpose or operation. In Fig. 1, there are also shown the plural number (in the embodiment, three pieces of cards) of the electronic money IC cards 100, 110 and 120, and on the respective main surface thereof are provided with contact portions 101, 111 and 121 at predetermined position thereof, for electrical connection. Further in Fig. 4, there is shown the structure of the electronic money IC cards 100 in more detail, and as is clear from the drawing, in the present embodiment, each of those contact portions 101, 111 and 121 is composed of a group of eight contacting points 101a through 101h. And, in the drawing, a reference numeral 102 shows an emboss portion, in which, for example, a name and/or a mark of a bank and/or a company which issues the electronic money IC card are/is pressed or formed in relief. Further, though not shown in the drawings, in addition thereto, for example, also so-called a ten key, a button for money transfer and so on can be provided on the main body 10 of the of the portable terminal device, thereby to make it possible to transfer a desired amount of the electronic money from a one electronic money IC card to an another electronic money IC card, by designating or inputting the amount with those buttons on the portable terminal device. For example, with this, by inserting the respective electronic money IC cards owned by a father and his child or children into the slot opening 12 of the portable terminal device and by manipulating the above buttons thereof, it is possible to transfer the electronic money between them, i.e., the IC cards of father and his child or children. Also the transfer of the electronic money between the electronic money ICcard owned by a friend can be possible in the same manner. Further, also in the same manner, the transfer of the electronic money is possible between the plural electronic money IC cards owned the user himself, between the electronic money IC card for use in saving in bank and that for paying consumption by him, for an instance. Fig. 2 shows a perspective view of an external configuration of the portable terminal device for electronic money IC cards of the present invention from reverse side thereof. As is apparent form the drawing, on the reverse side surface wall of the main body 10 of the portable terminal device, there is provided an opening of an oval shape penetrating to the card slot opening 12. With this construction, when trying to take out the electronic money IC card (s) which is/are inserted into the slot opening 12, it/they can be easily slid out from the slot opening 12 by pushing a finger (for example, a thumb) on and moving it aside. In Fig. 3 showing the cross-section view of the portable terminal device for electronic money IC cards in accordance with the first embodiment of the present invention, only one substrate 19 is positioned inside of the main body 10 of the device, on the surface of which are provided a plurality of electric contact terminals 16, 17 and 18. On the surface of the substrate 19, not shown in the drawing, however, there are also mounted various circuitry elements including a micro-processor, memory device, etc., which are necessary for carrying out processing and displaying operating as of the portable terminal device for electronic money IC cards. And, the plural electronic money IC cards 100, 110 and 120 (three pieces of IC cards, in the present embodiment) are inserted into the slot opening 12 of the main body 10 of the device, as depicted by broken lines, being closely piled up with each other and shifted to each other by a predetermined distance d in the longitudinal direction on the main surface of the IC card. Here, the predetermined distance d corresponds to the length from a front edge portion up to the contact portion 101 of the electronic money IC card 100. On a bottom face of each of those plural electric contact terminals 16, 17 and 18, as clearly shown in attached Fig. 5, eight spring terminal pins of "U" shape are provided corresponding to the eight contact points 101a through 101h of the contact portion 101 of the electronic money IC card 100. Though the transfer of the information of electronic money between the electronic money IC card 100 is established through electrical connection therebetween in the embodiment mentioned above, not being restricted only to this, however, it also can be established optically through an optical coupling therebetween. In the construction of the portable terminal device for electronic money IC cards mentioned above, the electric contact terminals 16, 17 and 18 are connected with the electric contact portions 101, 111 and 121 of the plural IC cards 100, 110 and 120 which are inserted into the slot openings, respectively. Namely, those electric contact terminals 16, 17 and 18 of the substrate 19 are so constructed that the height of them are gradually decreased from a left-hand side to a right-hand side on the drawing. Under the condition of this, the portable terminal device is able to read out the respective contents of the electronic money IC cards inserted and to write into them. Also, as is apparent from the drawing, a guide member 20 which is bent or wound in "U" shape and made of spring material is provided in the main body 10, with which the plural IC cards 100, 110 and 120 being inserted from the slot opening 12 are guided in the order of the insertion to the predetermined positions 130, 140 and 150, i.e., from the bottom to the top in the slot opening 12. In this manner, the electric contact terminals 16, 17 and 18 are positioned on the surface of the same substrate 19 within the card slot opening 12 and the plural IC cards are inserted under the condition that they are piled up with and sifted to each other, therefore, it is possible to reduce the thickness of the device itself in more and to obtain a small-sized portable terminal device for electronic money IC cards as a whole. However, with the portable terminal device for electronic money IC cards of the present embodiment mentioned above, as shown in the drawing, the second IC card and the third IC card are inserted with projecting the rear edge portions thereof from the slot opening 12, and the length of the device is nearly equal to that of IC card in the direction of insertion thereof.
