On the other hand, a name coincident with the inputted three characters is searched from an RAM2A9 at the search mode and when the coincident name is found out, an RAM2S being paired to an RAM2A is designated, the numeric code in the RAM2S is transferred to the RAM1S, and the telephone number corresponding to the said name stored in the said RAM1S is read out.

Description

Detailed Description of the Invention (a) Technical Field The present invention relates to an automatic dialing device that stores a large number of telephone numbers and automatically sends a selected telephone number to a telephone line by a simple operation by the user. .

(b) Background of the technology Generally speaking, when making a telephone call, one operates the dial or button on the telephone, but each time a telephone call is made, one often looks up the telephone number or relies on a vague memory. In addition, some telephone numbers have more than 10 digits, including area code, etc., so it takes time to operate them, and there is a high probability of making a mistake. Therefore, an automatic dialing device has been developed that can store frequently used telephone numbers in advance and send out the telephone numbers with a simple operation.

However, conventional automatic dialing devices are provided with a number of selection keys equal to the number that can store telephone numbers, and the name of the other party is written on or near the selection keys. Such automatic dialing devices require a space to write names, etc., making the device large as a whole, making it unsuitable for portable use, and it is usually installed near a telephone set and connected to a telephone line. Furthermore, if the other party's name changes, it is necessary to rewrite it on a new form, which is an annoying drawback.

(C) Disclosure of the Invention The present invention has been made in view of the above-mentioned points, and is a first method that stores a plurality of character codes input using character keys.
and a second area that stores a plurality of numeric codes entered using the numeric keys are set as a pair, and when the storage means consisting of the plurality of pairs and the address of the first area of the storage means are designated, the predetermined key When an operation is performed, an address specifying means is provided for specifying an address of a second area that is paired with the specified first area, and the name, etc. and telephone number are stored as a pair in the storage circuit. By doing so, it is not necessary to write the name of the other party near the selection key, and it is possible to provide an automatic dialing device that is portable.

B) Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention. The sound generating means (1) is, for example, a speaker, and when transmitting the telephone number, it is acoustically coupled to the mouthpiece of the telephone and transmits sound at a predetermined frequency, thereby transmitting the telephone number. That is, a number is represented by combining two sounds of a specified frequency, and the frequency and the method of combination are determined by the standard. For example, the number "1" is 697H
It is represented by a combination of a frequency of z and a frequency of 1209Hz. Based on the above-mentioned standards, the acoustic signal generating means (2) generates an acoustic signal combining two types of frequencies representing the number when numerical data is applied via the data bus (3), (1).

The transmission time of the telephone number consists of, for example, 0.5 seconds of sound and 0.5 seconds of pause for each character, but it is also possible to change and select this time from the outside using a switching means or the like.

The display device (4) consists of 1 digit of 5 x 7 dots and 16
It consists of a liquid crystal display board that can display digits and a drive circuit that drives it. Character codes or numeric codes, etc. applied via a data bus (3) are stored in the memory inside the drive circuit, and the data is stored in the memory inside the drive circuit. It is used to display characters or numbers based on .

The keyboard (5) consists of letter keys from the alphabets rAJ to rZJ, numeric keys, function keys, and other keys, and the key closing of the keyboard (5) is carried out by key scanning of the key manual means (5). It will be done. When the key scan detects the closing of a character key, the key manual means (6) sends an 8-bit character code corresponding to the character key to the data bus (3), and detects the closing of a numeric key. When this happens, an 8-bit numeric code is sent to the data bus (3). Furthermore, when opening of a function key is detected, each unit is controlled to implement the function instructed by the function key.

RAMI (7) is used to store the character code and numeric code being processed.
It consists of a RAM 15 consisting of 8 x 16 bits that stores 6 digits, and performs the operation of storing character codes or numeric codes entered manually on the keyboard (5), and sends the stored data to the data bus (3). It operates and sends and receives data to and from the RAM 2 (9) via the data bus (8).

, RAM 2 (9) is a storage circuit consisting of a plurality of pairs, for example, 60 pairs, with a first area for storing 16 characters and a second area for storing 16 digit numbers. The area and the second area have a capacity of 8 bits x 16, and an 8-bit character code or numeric code is specified in one address specification. Also, RAM 2
(9) is backed up by a battery so that the data is retained even if the automatic dialing device is turned off. An example of the allocation of RAM2 (9) is shown in FIG. In Figure 2, for example, addresses "00" to
A pair of 32 addresses, such as IFj (hexadecimal number) addresses ``20'' to ``3F'', is used, and the first 16 addresses are the first area (RAM2A), and the latter 16 addresses are the second area (RAM2A). RAM2S).

Names are stored in the RAM 2A using 16 alphabetic characters, and telephone numbers are stored in the RAM 2S using 16 digits.

The address of this RAM2 (91) is
It is specified by an 11-bit address signal (12) output from υ. Addressing means (1υ is controlled by key manual means (6) or search means (1),
It has a function of addressing only AM2A, a function of addressing only RAM2S, and a function of addressing TtAM2A and RAM2S as a pair.

When RAM2A is addressed, data is sent to and received from RAMIA, and when RAM2S is addressed, data is sent to and received from RAM15.

Search means (+31 is a function key on the keyboard (5) that searches for letters or numbers in RAM2 (9)K)
When the "5TORE key" used for memorization is closed, the function of searching RAM2 (91) free RAM2A and RAM2S and storing characters or numbers there, and the character of the keyboard (5). When three or more characters are input using a key and the S E A RCH key, which is one of the function keys, is closed, the three characters are memorized, the two RAMs are searched in order, and the RAM is
By comparing the first three characters of 2A, it has a function of storing the first address of RAM 2A where a character matching the input three characters is stored.

Next, the operation and function of the embodiment shown in FIG. 1 will be explained with reference to FIGS. 3 to 6. .

As shown in Figure 3, first, when the automatic dialing device is powered on, initial settings such as clearing the display device (4) and RAMI (7) are performed, and the cursor is moved to the first digit of the display device (4). Display. The cursor is used to indicate the location where characters or numbers are displayed when they are entered manually, and is also used to modify the characters or numbers using the shift key or the like. And then, “A”~
It detects the closure of the character keys and number keys up to rZJ, but since character storage is prioritized over number storage, a character flag FLG is provided to indicate that a character has been stored in RAM2A, and the character Number keys are captured only when flag FLG is set.

When it is detected that the character key is closed, the character storage or search mode is entered, and when the closing of the numeric key is detected while the flag FLG is set, the telephone number storage mode is entered.

When the character storage or search mode is entered, as shown in Fig. 4, the character code manually input by key is stored from the upper digits of RAMIA, and the character is displayed at the cursor position on the display device (4), and the crab crane moves to the next Shifted to the digit. Then, it is determined whether the number of characters stored in RAMIAK is three or more, whether a character key is closed, whether the "5TORE key" is closed, or whether the "CLEAR key" is closed. Here, if a character key is closed, the character code is stored in RAMIAK and the character is displayed on the display (
4) will be displayed sequentially. If the number of stored characters is 3 or more but less than 16 characters, it is determined whether the "5EARCH key" is closed and the same operation as described above is performed, and if the number of characters is 16, the "5EARCH key" is pressed. Determine the closure of
In order to invalidate the input of a character key, no determination is made as to whether the character key is closed.

When the ``5 EARCH key'' is closed in the case of 3 or more characters, the search means (1) is activated and enters the search mode. ) is the key to search for the name stored in the memory. In this way, by closing the character key, the name indicated by up to 16 alphabetic characters is stored in RAM IA, and the character is displayed on the display device (4). is displayed. Then,
When the "5TORE key" for transferring data to the RAM 2A is closed, the address designating means 0υ sequentially designates the top address of the RAM 2A and determines whether a character code is stored in the RAM 2A. As a result, if all RAM2A has character codes, display device (4) K rOVE
The characters RFLOWJ are displayed for 1 second, and RAM2A
If there is a free space in
Let A memorize the RAMIA character code in 16-character order,
After setting the character flag FLG, the RAM 1 (7) and the display device (4) are cleared and the process returns to the section AA in FIG. Further, when the ``OLEAR key'' is closed during the process, the RAMI (7) and the display device (4) are cleared. In this case, the input characters are not stored in the RAM 2A.

When characters are stored in the character storage mode described above, input using the numeric keys becomes possible as shown in FIG. Then, when the numeric keys are closed, the telephone number storage mode shown in FIG. 5 is entered. That is, the numeric code sent from the key input means (6) is stored in the upper digits of the RAM 15O, and the numeric code is displayed at the cursor position on the display device (4), and the cursor is shifted to the next digit. Then, whether the number of digits stored in RAM15 has reached 16 digits or whether the numeric key is closed,
``5TORE key'' is closed or ``CLEAR''
It is determined whether the ``key'' is closed or not. By closing the numeric key, the numeric code is sequentially stored in the RAM 15 and displayed on the display device (4).

When the number stored in the RAM 15K reaches 16 digits, the closing of the numeric key is not detected and the capture of the numeric key is stopped. In this way, the telephone number is stored in the RAM 15K, and when the "5TORE key" is closed, the address specifying means (11) selects the starting address of the RAM 2S that is paired with the RAM 2A that previously stored the character code. After specifying and storing the numerical code of RAM15 in RAM2S in sequence, reset the character flag FLG and write RAMI (7
) and display device (4) and return to AA. Also, if the "CLEAR key" is closed during the R
Clear the AMI (71) and display device (4). In this case, no telephone number is stored in the RAM 2S.

Through the operations described above, the name and telephone number are stored in pairs in the RAM 2 (91).

Further, as shown in FIG. 4, when three or more characters are entered manually and the search key is closed, the search mode shown in FIG. 6 is entered. The search mode is a mode in which a name matching the three input characters is searched from the RAM 2 (9) and sent by pressing the ``DIAL key''. When the search mode is entered, the top three characters stored in RAMIAK are used as the search method α3.
and the addressing means Ql) are stored in all RAM
2A addresses are sequentially designated, the upper three characters of each RAM 2A are taken out from the RAM 15K, and the retrieval means CI3 compares them with the stored three characters. If there are no matching names as a result of the search, display device (4) K rNOT FOUNDJ
After that, by closing the "CLEAR key", RAMI (7) and display device (4) are cleared and the process returns to AA. If there is a matching name,
All RAM2A memory with the matching name
The first address of 1 is stored in the address specifying means aυ, and the address specifying means θl) first specifies the RAM2A with the smaller first address.
The character data of 6 characters is transferred to RAMIAK, and then the characters are displayed on the display device (4). And “PAGE
key","NUMBER key","DIAL key","
Waits for the ``CLEAR key'' to be pressed. When the ``PAGE key'' for sequentially displaying search results is closed, the next RAM stored in the addressing means aυ is
By the start address of 2A, the character code stored in RAM 2A is transferred to RAM 1A, and the character code stored in RAM 2A is transferred to the display device (4
). Therefore, matching names are displayed one after another by operating the "PAGE key". In this case, if there is only one matching name, even if the "PAGE key" is operated, the display will not change because there is only one stored starting address.

Then, due to reasons such as not having the desired name, "CLE"
When the "AR key" is closed, RAMI (7) and display device (4) are cleared and returns to AA.

Furthermore, when the "NUMBER key" is closed, the address specifying means 01), which stores the address from which the character displayed at that time was read, specifies the address paired with that address. RAM2S, which is paired with RAM2A that stores the displayed characters, is designated, and the numerical code of RAM2S is transferred to RAM15K, and the telephone number corresponding to the name is displayed on the display device (4) using the numerical code of RAM15. be done. Then, it waits for the operation of the ``DIALDIAL key LEAR key'', and when the ``DIAL key'' is closed, the RAM15
K The stored numeric code is sequentially applied to the acoustic signal generating means (2) every second starting from the most significant digit, and the sound generating means (1) generates a sound with a frequency corresponding to the number, and the number being sounded is In order to clearly indicate this, the corresponding number on the display device (4) is made to blink. This operation causes the telephone number to be sent. On the other hand, if the "CLEAR key" is closed,
Only the phone number is displayed, no pronunciation is made, and RAMI
(7) and display device (4) are cleared and returns to AA.

That is, in this case, the mode is simply to confirm the telephone number.

On the other hand, after searching, display only the name and press the "DIAL key"
, the addressing means 0υ specifies the RAM 2S paired with the display at that time, transfers the numerical code stored in the RAM 2S to the RAM 15, and transfers the numerical code stored in the RAM 2S to the display device (4 )K, and then R
The numerical code is sequentially sent to the acoustic signal generating means (2) starting from the upper digit of AMl5O, and the telephone number is sent out. Of course, the number being sounded is flashed and clearly indicated on the display device (4). When the transmission is completed, RAMI (7) and display device (
4) is cleared and returns to AA. That is, in this case, the telephone number is sent directly from the user's name without confirming the telephone number.

In this way, the RAM 2 (91) is configured as a pair of the first area RAM 2A for storing characters and the second area RAM 2S for storing numbers, and by making each pair addressable by the addressing means aυ, A name and a telephone number can be stored as a pair, and when read out, a name and a telephone number can be read out as a pair.

(e) Effects As described above, according to the present invention, since a name and a telephone number can be stored in pairs, there is no need for a space for writing a name on an automatic dialing device, and miniaturization is possible, making it possible to use a portable automatic dialing device. can be realized.
