It is designed to be displayed.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Figure 2 shows I as a portable storage medium according to this invention.
This figure shows an example of the configuration of a card handling device to which a C card is applied, which is used as a terminal device in an address search system, for example. That is, this device has an IC card 1
can be connected to a control section 3 consisting of a CPU or the like via a card reader/writer 2 serving as a card processing device, and a keyboard 4 and a display section 5 are connected to the control section 3.

The IC card 1 is held by a user and used when searching for a telephone number or address. For example, as shown in FIG. It is composed of a data memory 12, a program memory 13, and a contact part 14 for obtaining electrical contact with the card reader/writer 2. The memory 13) is composed of one IC chip. The program memory 13 is composed of, for example, a mask ROM, and stores a control program for the control element 11 including subroutines for realizing various basic functions.

The data memory 12 is used to store various data, and is composed of, for example, an EEF ROM.

As shown in FIG. 4, the data memory 12 is composed of an index area 12a and an address book area 12b. The index index area 12a is the fifth
As shown in the figure, a record number is stored for each initial letter (search keyword) of a name, etc. For example, the first letter code corresponds to the initial letter "A", and the first letter "A" corresponds to the first letter "A".
The second record corresponds to "1". The address book area 12b is made up of a plurality of variable length records. One record is composed of stored data and length information indicating the length of this stored data. As the stored data, as shown in Figure 6, a plurality of address book data consisting of names, telephone numbers, and addresses are stored, and one record stores a plurality of address book data corresponding to the same initial letter. It is now possible to do so. For example, the name corresponding to “A” in the first code (address book data)
The one of ``Capital Makoto 03-111-2'' is remembered.
111 Tokyo... Aoba 044-022-222
2 Kanayo prefecture...'' is memorized.

The card reader/writer 2 is used to exchange function codes and data between the IC card 1 and the control section 3. Specifically, as shown in FIG. 7, there is a transport mechanism 21 that transports the IC card 1 inserted into a card insertion slot (not shown) to a predetermined position, and a transport mechanism 21 that transports the IC card 1 inserted into a card insertion slot (not shown) to a predetermined position.
A control circuit 2 consisting of a contact portion 22 that is electrically contacted with the contact portion 18 of the controller, and a CPU that controls the entire control circuit.
3. It is composed of an input/output interface circuit 24 for exchanging command data and response data between the control circuit 23 and the control section 3, and a data memory 25 for storing data.

The keyboard 4 is comprised of 50-syllabary keys, a numeric keypad, etc. that allow input of names, telephone numbers, addresses, etc.

The display section 5 is constituted by a CRT display device or the like, and displays searched names, telephone numbers, addresses, etc.

Next, the operation of registering telephone numbers and addresses in the above configuration will be explained with reference to the flowchart shown in FIG. First, the IC card 1 is inserted into the card reader/writer 2. Next, the user enters the registration mode using the keyboard 4, and inputs his/her name, telephone number, and address. Then, the control unit 3 transmits the name, telephone number, and address to the control element 11 in the IC card 1 via the card reader/writer 2.
Output to.

As a result, the control element 11 stores the name, telephone number, and address in the record corresponding to the initial letter of the supplied name. At this time, the length information of the record is updated.

For example, the 10th record corresponding to "To" is "Tokyo".
-03-111-2111 Tokyo..." is stored, and the registered data is "Tokyo Tabe 03.
-222-2222 Tokyo..." is supplied, the 10th record "Tokyo -03-111-211
1Tokyo…” followed by “Tokyo Abe 03-222-”
2222 Tokyo...” is stored, and the length information L1
0 is updated.

Additionally, if the initial letter of the data to be stored in the data memory 12 has not yet been registered, a record number corresponding to the position in alphabetical order is assigned, and the record number for subsequent initial letters is increased by "+1". Update.

For example, when index data is stored as shown in Figure 5, and a name, telephone number, and address corresponding to the initial letter "I" are registered, "I" becomes the second record. , "tsu" becomes the third record from the second record, and the record number increases by "+1" thereafter.

Next, the search operation for telephone numbers and addresses will be explained with reference to the flowchart shown in FIG.

First, the IC card 1 is inserted into the card reader/writer 2 (STI). Then, the search mode is set using the keyboard 4 (Sr2). Then, the control section 3 displays the display section 5.
Then, the user is prompted to "enter the desired initial letter manually" (Sr1). In response to this guidance, the user selects keyboard 4.
Enter the desired initial letter (Sr1). Then, the control unit 3 inputs the initial letters to the IC via the card reader/writer 2.
It is output to the control element 11 in the card 1.

As a result, the control element 11 determines the record corresponding to the supplied initial letter based on the index index data of the index index area 12a, and stores the stored data corresponding to the determined record, that is, the first name stored,
Read phone number and address from address book area 1.2b.

At this time, the control element 11 determines the start address corresponding to the record number by checking the length information stored for each record in the address book area 12b, and searches for the start address of the desired record. There is.

Then, the control element 11 receives the name, telephone number, and
The address is output to the control unit 3 via the card reader/writer 2. Thereby, the control unit 3 displays the supplied name, telephone number, and address on the display unit 5 (Sr1). If the displayed name, telephone number, and address are not the desired ones, the user instructs the next display (Sr1). Then,
The control unit 3 outputs the next display instruction to the control element 11 in the IC card 1 via the card reader/writer 2.

Accordingly, the control element 11 reads out the name, telephone number, and address stored second in the record from the address book area 12b in response to this instruction.

The control element 11 outputs the name, telephone number, and address to the control section 3 via the card reader/writer 2.

As a result, the control unit 3 controls the supplied name, telephone number,
The address is displayed on the display unit 5 (Sr1).

Thereafter, each time the next display is instructed, the stored data of the same record is displayed one after another. and the desired phone number,
After the address is displayed, the user issues an instruction to end the process, thereby ending the process.

For example, when "T" is supplied as the initial letter, the control element 11 determines that the corresponding track is the 10th track based on the index index data in the index index area 12a, and stores data corresponding to the determined 10th record. "Tokyo -03-111-2111 Tokyo..." is read out from the address book area 12b as the first stored name, telephone number, and address. At this time, the control element 11 searches for the start address of the desired record according to the record number "10" and the length information stored for each record in the address book area 12b.

That is, first, the start address of the second record is determined from the length information of the second record, the start address of the third record is determined from the length information of the second record, and... from the length information of the ninth record. Determine the starting address of the 10th record.

Then, the control element 11 is the “Tokyo 03-11” searched above.
1-2111 Tokyo...'' is output to the control unit 3 via the card reader/writer 2.

As a result, the control unit 3 controls the supplied "Tokyo -o3-
111-211i Tokyo...'' is displayed on the display unit 5.

In addition, in response to the next display instruction, the control element 11 sets "Tokyo Tabe 03-222-2222 Tokyo..." as the name, telephone number, and address stored second in the record. The data is read from the recording area 12b. The control element 11 is connected to the Tokyo Abe 03-222-2222
"Tokyo..." is output to the control unit 3 via the card reader/writer 2. As a result, the control unit 3 receives the supplied "Tokyo Abe 03-222-2222 Tokyo...
” is displayed on the display unit 5.

As mentioned above, when trying to search for a desired address from a large number of data items such as an address book, the initial letter of the name is specified, and the address corresponding to the specified initial letter of the name, The record in which the telephone number is stored is determined, and the address and telephone number stored in this record are read and displayed, so there is no need to read unnecessary address book data (data other than the relevant index). It is possible to shorten the search time.

In the above embodiments, an IC card is used as an example of a portable storage medium, but the portable storage medium is not limited to a card shape, and may be, for example, a block shape or a pencil shape. Also, other storage media may be used.

In addition, although we have explained the case where an address and postal code are stored in correspondence with a name as a search keyword, this is not limited to cases where either an address or a postal code is stored in correspondence with a name. Even if it is, it can be implemented in the same way.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a registered data search device that can reduce search time.
