Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a portable electronic device of the present invention and a contactless IC card or an IC telephone card. As shown in FIG. 1, a power switch key 12, keys 13 such as alphanumeric characters for input, alphabetical characters, numerals, kana, etc. For example, the shift key and F1 in the figure
A function key 14 and a liquid crystal display unit 15 represented by F5 to F5 are provided. Function keys are, for example,
Functions such as “read phone number”, “write phone number”, “transfer phone number”, “transfer phone number instantly from A card to B card”, and “read frequency” can be provided. An opening 111 for inserting a card, which is connected to a card storage unit, is provided on a side surface of the housing 11. Note that 112
Is a notch for facilitating card withdrawal.

On the other hand, a contactless IC card (which may be an IC telephone card or a telephone directory card) 2 is formed by incorporating a control IC 22 in a card base material 21 such as hard vinyl chloride. Since it is contactless, a terminal for connection to the outside is not formed, and data communication and power supply to the outside are performed by an electromagnetic wave, a high frequency, or the like via the antenna coil 23 which cannot be observed from the outside. Control I
C22 includes a microprocessor, a memory, and the like.

[0010] The size of a telephone card is usually 54 mm width x
A thickness of 86 mm × 0.76 mm is common and is defined by the ISO standard, but a contactless IC telephone card is becoming thinner. Therefore, 0.5mm thickness and 0.
A 25 mm thickness is also being adopted for telephone cards. Therefore, the card insertion opening 11 of the housing of the electronic device according to the present invention.
The card storage unit 1 and the card storage unit may be any suitable for the thickness of the card. Note that a telephone directory card is a card dedicated to recording telephone numbers, which is similar to a telephone card and has a built-in IC and can write and read telephone numbers without contact.

FIG. 2 shows a contactless I in an electronic device housing.
This shows a state where the C card is inserted and stored. 2A is a perspective view thereof, and FIG. 2B is a cross-sectional view taken along line AA of FIG. 2A. The key arrangement of the electronic device and the like are omitted because they are the same as in FIG. In case of contactless IC card, about 80% of the card is stored and IC
As long as the antenna coil 23 of the card and the antenna coil 18 of the electronic device can communicate with each other, there is no problem in transmission and reception between the electronic device and the card. Of course, even if the entire card is stored, there is no problem if the housing is provided with a mechanism for extracting and pushing out the card.

Normally, a key for writing or reading a telephone number is input to the IC card or the telephone card 2 in the state shown in FIG. 2 (A) or (B). For example, the telephone number to be written is input from the alphanumeric key 13 or the like, and the telephone number is written to the telephone card 2 by inputting the function key “write telephone number”. Also, if you use the "Read phone number" function key,
The telephone number recorded in the telephone card 2 is displayed on the display unit 15.
Will be displayed. At this time, the write data is stored in the control circuit unit 1.
6 is transmitted to the antenna coil 23 of the telephone card via the antenna coil 18 and recorded in the memory. For reading data, the telephone card 2 reads the data in the memory in response to a call signal of the electronic device 1, and the control IC 22 reads the data in the memory, and transmits the data to the antenna coil 18 of the electronic device 1 via the antenna coil 23.

FIG. 2C shows a state in which two contactless IC telephone cards are inserted and stored in the electronic device housing.
Either or both of these may be telephone directory cards. In the case of FIG.
The function is described in detail later, but is intended to execute the function key "A phone number is instantaneously transferred from the A card to the B card". . Accordingly, in the case of FIG. 2C, when the thickness of the contactless IC telephone card or the telephone directory card is 0.76 mm, the thickness (gap) of the opening 111 and the storage 113 of 1.7 mm is smaller than that of the card. 0.5mm thick
Is 1.1 mm, 0.25 mm is 0.6 mm
A degree is desirable. Since it is contactless, even if the card thickness is 0.25 mm, there is no problem in reading and writing as long as the card can be inserted with the opening and the storage part being 1.7 mm.

At the time of these transfer instructions, a call signal is transmitted from the electronic device 1 to the telephone cards 2 and 3, and a response signal is transmitted from the telephone card in response to the call signal. However, if a response is made simultaneously from a plurality of telephone cards, data collision (collision) occurs, and the electronic device cannot determine which card the signal is coming from, and transmission / reception stops. This problem is also solved by the anti-collision function as described later.

FIG. 3 is a block circuit diagram according to the electronic device of the present invention. It comprises keyboard units 13 and 14, a (liquid crystal) display unit 15, a control circuit unit (IC) 16, and a power supply battery unit 17. Although not shown, the control circuit unit includes a receiving circuit and a transmitting circuit for transmitting and receiving to and from the IC card through the antenna coil 18. It also includes a memory for storing data read from the card and key-input data. The control circuit unit 16
It also has functions for controlling the display unit 15 such as transmission and reception with a card and liquid crystal. The control circuit section includes a power supply battery section 17.
Is supplied with power.

The function of the electronic device according to the present invention will be described below with reference to FIGS. Insert the contactless IC telephone card 2 through the opening 111 of the electronic device 1,
The key 13 is used to input the telephone number of the other party to be registered frequently. The input data is displayed on the display unit 15. It is sufficient for the display unit to display 10 digits and 2 lines, but the display unit is not limited to this. Enter the destination name in katakana and enter the telephone number in numbers. When displayed, press the "write telephone number" key of the function key to register it on the card. The number of registrations depends on the memory capacity of the card and how many can be registered.

If the card has a telephone number already registered, the data can be read out. By pressing the "read phone number" key, the data in the card is read and displayed on the display unit. A contactless IC telephone card is generally disposable (there is no other choice than discarding it when the frequency is exhausted). Therefore, a newly registered telephone number must be newly registered when a new telephone card is purchased. Registering using a public telephone hinders the original telephone call function. Using this electronic device, it is possible to personally register at any time, and the same telephone number can be transferred and registered from an old card to a new card.

At this point, the card which has been used up (although the same is true on the way) is used as an A card, and a new card (even if it is not new, if it is desired to register the same telephone number on this card) is used as a B card. A card is used to explain how to use a telephone card. First, the telephone number is read from the A card and temporarily stored in the memory of the electronic device. Remove the A card from the electronic device and insert the B card. Here, by pressing the "transfer phone number" key of the function key, the same phone number is registered in the B card. Although expressed as a "transfer phone number" key, it can be freely called as long as the functions are the same.

The case where the A card and the B card are replaced has been described above. However, the electronic device is provided with an anti-collision function, and a plurality of cards are simultaneously inserted and identified, and the telephone number is transferred. Can be. The anti-collision function means that when a plurality of cards are inserted as described above and a response signal is transmitted from the card, signal collision occurs. The signal collision is detected, and a time slot method, a bit collision method, etc. Is used to identify and select cards. As a result, it is possible to insert the two cards A and B and transfer the telephone number without replacing the card by the same key operation as described above. This operation is performed by pressing the function key “A card → B
The instantaneous transfer of the telephone number to the card is performed. The data is transferred and written without being temporarily stored in the electronic device or displayed on the display unit. Therefore, in preparation for such a case, the opening 111 and the card storage unit 113 have a space for two cards.

In addition to the function of reading the telephone number of the card, the present electronic device has a function of displaying the remaining number of the telephone card. As a result, the remaining number can be recognized at any time, and before the frequency reaches "0", the telephone number is transferred to a new card and registered. Lost telephone numbers can be avoided. This operation is performed by the function key “frequency reading”.

Materials for forming the housing of the electronic medium include:
Use a material that is relatively rigid and easy to process, such as hard vinyl chloride resin, ABS resin, or epoxy resin. In addition, cellulose, glass fiber, for improving strength and heat resistance,
Calcium carbonate or the like may be mixed.

In the present application, the portable electronic device of the present invention is mainly described as handling telephone numbers as data. However, it is obvious to those skilled in the art that the present invention can also be applied to handling data other than telephone numbers. And is not excluded.

[0023]

As described above, the portable electronic device of the present invention is capable of writing and reading data or telephone numbers to and from a contactless IC card, a telephone card, and a telephone directory card. It can also be displayed on the display unit. Further, it is possible to easily transfer the already written data or telephone number to another IC card or telephone card. Accordingly, there is no need to perform writing via a special input device or a public telephone, and the user can carry the telephone number and read, transfer, or transfer / write the telephone number at any time while carrying it personally. Furthermore, in the preferred embodiment of the present invention, since the remaining number of contactless IC telephone cards can be known, the convenience for the user is further enhanced.
