Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is capable of writing a person's name, name, etc. and a corresponding telephone number as data on a recording medium such as an IC card or an optical memory card, and is also capable of being recorded. The present invention relates to a telephone number data writing/reading device that can read existing data and search based on specified conditions.

[Prior Art] Generally, in order to make a telephone call, it is necessary to enter the desired telephone number into the telephone by dialing, pressing a button, etc., relying on memory or while looking at a memo or the like.

By the way, if you don't know the desired phone number, first search for the desired phone number by looking in a phone book that you personally created using a notebook, etc., and then, based on the number you found,
It is common to make a telephone call using the procedure described above.

However, even in a personal telephone directory, if a large amount of data is recorded, there is a problem in that it takes time and effort to find a desired number. Particularly, when it is unclear whether or not the desired telephone number is recorded in the personal telephone directory, this method has the drawback of requiring additional effort.

As a countermeasure for this problem, there has been a system in the past that allows users to make a call by inputting about three digits using a compressed dial for a pre-registered telephone number. There is also a punch card with a telephone number punched in advance, which can be inserted into a card reader of a telephone equipped with an automatic dialing device to make a call. be.

[Problems to be Solved by the Invention] However, with the above-mentioned speed dial system, the number of registrations is limited, and it can only be used for specific registered telephones, and cannot be used for unregistered telephones, public telephones, etc. There is a problem that there is no practical solution for the reason that it is impossible to solve the problem.

On the other hand, with the punch card method, a punch card is created for each call, so it is convenient if you frequently call a small number of callers, but it is convenient if you make frequent calls to a small number of people. It is inconvenient to carry around, and it is not suitable for targeting a large number of unspecified people.

Therefore, it has recently been proposed to record personal names and corresponding telephone numbers as data using a recording medium such as an IC card or an optical memory card to form a card-type telephone directory. According to this method, a large number of telephone number data can be stored on one card, making it possible to create a convenient phone book for carrying.Furthermore, it is possible to quickly search for necessary data from among a large number of recorded data. You can expect the effects that can be achieved.

In order to realize a telephone directory using such a recording medium, telephone number data can be recorded in the telephone directory, and
There is an urgent need to develop a telephone number data writing/reading device that can read and search recorded telephone number data.

The present invention was developed in view of the above circumstances, and is capable of recording a large amount of telephone number data and quickly and accurately detecting target telephone number data from a large amount of recorded data. The purpose is to provide a reading device.

The data to be filled in can be entered directly using an input method, or
Data from another recording medium can be transferred and inputted. For example, if the recording medium is an IC card, digital data can be written in the RAM of the card in a format that is directly transferred from the writing means. . Further, in the case of an optical memory card, digital data to be written is converted into an optically changed state such as a pattern of changes in reflectance on a recording medium using a light beam, and then written.

The reading means reads a person's name, name, etc. and a corresponding telephone number from the recording medium as data. For example, if the recording medium is
If it is a C card, digital data is read from ROM or RAM in a format that is directly transferred. In addition, in the case of an optical memory card, a light beam is irradiated from an optical head, an optical change pattern such as reflectance is detected, and the data is read by converting it into an electrical signal. The read data is stored in internal memory.

The search means searches for specified data from the data recorded on the recording medium. A search can be performed simply by sequentially reading data from a recording medium, comparing it successively with the target search conditions, and repeating this operation until data matching the conditions is found. The means for faster searching differs depending on the type of recording medium, but for example, RA
If the medium uses M as a storage means, the internal memory of the reading means and the RAM are used to rearrange the data within the medium to perform the search.If the medium is a medium in which data cannot be rewritten, A large-capacity memory is prepared within the search means, data on the medium is read into this memory, and the array is rearranged to perform the search.

The output means outputs the data read by the reading means by displaying, printing, or the like. The data to be written and the search results can also be output.

The input means inputs data such as data to be written to the recording medium, data such as data search conditions, instructions, etc. from the outside. If not, enter the same code as the data, or if a code is provided, enter the code as a search condition. The input means also inputs instructions such as selection of data to be output by the output means.
Specify and instruct using the item number (list number) etc. assigned by the display means and print out.

[Example] An example of the present invention will be described with reference to the drawings. Note that this embodiment is an example in which an IC card is used as the recording medium.

Therefore, after data is searched, the correspondence between item numbers and data changes.

<Effect of the embodiment> Next, the operation of this embodiment will be explained.

``As mentioned above, this embodiment uses an IC card as the recording medium.

By the way, what information is recorded on the IC card?

Personal name, organization name, or abbreviation of these up to 16 characters in kana code, and telephone number up to 16 digits in numeric code. Numerical values and kana codes can be expressed in 8 bits, so for one personal data, that is, data for one case, (16 + 16) x 8 bits = 256
Bits are required.

The IC card applied to this embodiment stores data in the format shown in FIG.

In other words, data for one case is recorded in 256 bits as described above, and 128 bits are allocated to each name category and number category.In the 0 name category, 16 digits are allocated as kana code, and in the number category, 128 bits are allocated to each. Each of the 16 digits is set as a numerical code. In addition.

For convenience, the name classification is divided into 8 digits each for surname and first name.

Letters and numbers are recorded left-justified in each section, leaving empty digits intact in the l-data. This is to clarify the classification of each personal data.

With this format, the storage capacity of 64KB and IC
When data is recorded on the card, it can store information for 256 people.

Now, the operation when storing data of names and corresponding telephone numbers using the above format will be explained.

When the user inserts the IC card C into the card insertion slot 5, the card sensor 3 detects this, and this detection signal is A/D converted by the card detection circuit 4, becomes a constant code signal, and is sent to the CPU 1. via data bus 2.

In response to this detection signal, the CPUI displays the frame of the recording format on the display 10 via the display control circuit 9, as well as a message "data writable".

Using the keypad 11, the user enters the name of the person they wish to search for,
Enter the organization name or abbreviation and the corresponding phone number. These input data are sent to the key input circuit 12.
and sent to the CPUI via data bus 2. The CPUI temporarily stores these data in the memory 8. When the input data write instruction signal is input from the keypad 11, the CPU transfers the input data stored in the memory 8 to the IC card C via the card write circuit 16. Write.

Next, we will explain how it works when searching for a desired phone number and making a call to the searched number using an IC card with data written to it as described above to create a personal phone directory. do.

When the user inserts the IC card C into the card insertion slot 5, the card sensor 3 detects this, and this detection signal is A/I) converted by the card detection circuit 4 and becomes a constant code signal. It is sent via data bus 2 to the CPUI.

Upon receiving this detection signal, the CPU activates the card read circuit 6, reads data for each item from the inserted card, and stores it in the memory 8.

The data written in the memory 6 is converted into display data by the display control circuit 9, and displayed in the format described above with a display of $10.

While looking at this display, the user uses the keypad 11 to input the keyword of the individual name, organization name, or abbreviation thereof for which he or she wishes to search. The input keyword is encoded by the key input circuit 12 and sent to the CPU via the data bus 2.
Sent to I.

Note that if the data does not fit on one screen of the display 10,
You can view the screens one by one by pressing the "Page" key, which is a special function key on the keypad.

The CPUI selects data that includes information that matches this keyword from among the data stored in the memory 6, and
It is displayed on the display 10.

When the user finds the desired person from this display,
The user selects the list number (item number) of the data using the keypad 11 and gives an instruction to start a call.

The CPUI extracts data in the telephone number category from the data of the selected list number and sends it to the dial tone generation circuit 13. The dial tone generation circuit 13 decodes the sent number data, generates a dial tone for the other party, and sends it to the telephone line via the telephone line interface 14.

In this way, the telephone is connected to the other party, the user's call ends, and when the user instructs ejecting the card using the keypad 11, the CPU outputs a signal to the card ejecting solenoid 7, and the solenoid 7 is started,
Card C is ejected to card insertion slot 5.
