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, when making a call, one operates the dial or button on the telephone, but each time a call is made, the telephone number is looked up, or in many cases, the call is made by relying on vague memories. In addition, some telephone numbers have more than 10 digits including the area code, which increases the time it takes to use them and increases the chance of making mistakes. Therefore, memorize frequently used phone numbers in advance.
Automatic dialing devices have been developed that can send out telephone numbers with simple operations.

However, conventional automatic dialing devices are provided with a number of selection keys equal to the number that can store telephone numbers, and a sheet of paper on which the name of the other party is written is provided on or near the selection keys. These automatic dialing devices require space on paper to write names, etc., making the device large and unsuitable for portability; it is usually installed near a telephone and connected to a telephone line. ing. Additionally, if the other party's name changes, it must be rewritten on a new form.

(C) Disclosure of the Invention The present invention has been made in view of the above-mentioned points, and includes a first area for storing names, etc. input using the character keys, and a telephone number input using the numeric keys. and a second area for storing a plurality of pairs, a storage means comprising a plurality of pairs, an addressing means capable of specifying an address by pairing the first area and the second area of the storage means, and a predetermined number of characters. When is entered,
a search means that is activated by a predetermined key operation and detects a match with a predetermined number of characters of the name stored in the first area, and searches for all addresses in the first area that are detected as matches by the search means. By causing the address designation means to hold the names, and by operating other predetermined keys, the names stored in the first area designated by the addresses held in the address designation means are sequentially read out and displayed. The present invention provides an automatic dialing device that eliminates paper on which to write information, makes it compact and portable, and has excellent operability.

(d) 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 a telephone number, it is acoustically coupled to a mouthpiece of a telephone and transmits a sound of a predetermined frequency to transmit 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 represented by a combination of a frequency of 697Hz and a frequency of 1209Hz. Based on the above-mentioned standards, when numerical data is applied via the data bus 3, the acoustic signal generating means 2 generates an acoustic signal combining two types of frequencies representing the numerical value, and applies it to the sound generating means 1. It is something. The transmission time of the telephone number consists of, for example, 0.5 seconds of pronunciation and 0.5 seconds of pause for each character, but this time can also be switched and selected by external switching means or the like.

In the display device 4, one digit consists of 5×7 dots,
It consists of a liquid crystal display board capable of displaying 16 digits and a drive circuit that drives it. Character codes or numeric codes, etc. applied via the 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, numbers, etc. based on

Keyboard 5 is Alphabet “A” ~
It consists of character keys up to "Z", numeric keys from "0" to "9", and a plurality of function keys. In particular, the function keys include the "STORE key" to store characters or numbers entered using the letter or number keys, the "CLEAR key" to erase entered characters or numbers, and the "SEARCH key" to search for stored names, etc. ”, a “PAGE key” to display search results in order, a “NUMBER key” to display a telephone number, and a “DIAL key” to send a telephone number.

The closing of each key on the keyboard 5 is captured by the key scan of the key input means 6, and when the key input means 6 detects the closing of a character key or a numerical key, it inputs the 8-bit character code corresponding to that key. Alternatively, when a numerical code is sent to the data bus 3 and the closing of a function key is detected, each unit is controlled to operate the function specified by the function key.

RAM1(7) is for storing the character code and numeric code being processed; RAM1A is 8-bit x 16 that stores the character code for 16 characters, and 8-bit x 16 is used to store the numeric code for 16 digits. When a character or number is key-input on the keyboard 5, it stores the character code and number code, sends the stored character code or number code to the data bus 3, and Character codes or numeric codes are exchanged with the RAM 29 via the data bus 8.

RAM2(9) has a first area that stores character codes for 16 characters and a second area that stores numeric codes for 16 digits as a pair, and multiple pairs, for example, 60 pairs.
The first area and the second area each have a capacity of 8 bits x 16. The RAM 2 (9) is backed up by a battery 10 so that it retains data even when the power to the automatic dialing device is turned off. this
Figure 2 shows an example of RAM2(9) allocation. In Figure 2, for example, 32 addresses are paired, such as addresses "00" to "1F" and addresses "20" to "3F" (hexadecimal), and the first 16 addresses are in the first area (RAM2A ), and the latter 16 addresses are the second area (RAM2S). And for each pair
RAM 2A stores a character code, that is, a 16-character alphanumeric name, and RAM 2S stores a numeric code, that is, a 16-digit telephone number.
Further, each address of RAM2(9) is specified by, for example, a 13-bit address signal 12 output from the address specifying means 11.

The addressing means 11 is controlled by the key input means 6 or the search means 13, and has a function of addressing only RAM2A, a function of addressing only RAM2S, and a function of addressing RAM2A and RAM2S as a pair, Furthermore, it also has a function to memorize addresses when searching.

The search means 13 has the function of searching for the vacant RAM2A and RAM2S when the function key "STORE key" of the keyboard 5 is closed, and storing the name or telephone number entered therein, and When three or more characters are input using the character keys and one of the function keys "SEARCH key" is closed, the alpha alphabet of those three characters is memorized and RAM2A is searched in order, and each RAM2A is It has a function of detecting a match with the first three characters and, if there is a matching character, storing all the first addresses of the RAM 2A storing that character in the address specifying means 11.

The operation and function of the automatic dialing device configured in this way will be explained with reference to FIGS. 3 to 6.

In FIG. 3, when the automatic dialing device is first powered on, initial settings such as clearing the display device 4 and RAM1(7) are performed, and a cursor is displayed at the first digit of the display device 4. The cursor indicates where to display characters or numbers when they are input, and is also used to modify the characters or numbers by using a shift key or the like to move the cursor. Next, it detects when the letter keys and number keys are closed, but because it prioritizes remembering names, etc. over remembering phone numbers,
A character flag FLG indicating that a character is stored in the RAM 2A is provided, and numeric keys are detected only when this flag FLG is set. Therefore, when the closing of a character key is detected, the mode is set to character input, and when the closing of the numeric key is detected while the character flag FLG is set, the mode is set to telephone number storage mode.

Figure 4 is a flow diagram of the character input mode, and the character code corresponding to the closed character key is
The character is stored starting from the upper digit of RAM 1A, and the character is displayed at the cursor position on the display device 4, and the cursor is shifted to the next digit. Then, it is determined whether the number of characters stored in RAM1A is three or more, whether a character key is closed, whether the "STORE key" is closed, or whether the "CLEAR key" is closed. Here, when a character key is closed, the character code is stored in RAM1A in sequence, and the character is displayed in the next digit of the display device 4.If the number of stored characters is 3 or more and it fills 16 characters, If there is no SEARCH key, it detects that the "SEARCH key" is closed and performs the same operation as described above, and when the number of characters reaches 16, it determines that the "SEARCH key" is closed and disables character key input. Therefore, the character key is not determined.When the "SEARCH key" is closed when there are three or more characters, the search means 13 is activated and enters the search mode.The search mode will be described later.

In this way, by closing the character key, the RAM 1A stores a name or the like represented by up to 16 alphanumeric characters, and the characters are displayed on the display device 4. Therefore, when the "STORE key" is closed, some functions of the retrieval means 13 operate, controlling the address specifying means 11 and sequentially specifying the start address of RAM2A, checking whether the character code is stored in RAM2A or not. judge. and all, i.e., 60
If the character code is stored in RAM2A, the characters “OVER FLOW” will be displayed on the display device 4.
If there is free space in RAM2A, the address specifying means 11 specifies the smallest address therein, causes the RAM2A to sequentially store 16 characters of the character code stored in RAM1A, and sets the character flag. After setting FLG, RAM1(7) and display device 4 are cleared and the process returns to the section AA in FIG. In addition, in the middle of inputting a character key, “CLEAR
When the "key" is closed, RAM1(7) and display device 4 are similarly cleared.

When characters are stored in the RAM 2A through the above operations, input using the numeric keys becomes possible as shown in FIG. Therefore, when the number key is closed, the fifth
The phone number storage mode shown in the figure is entered. That is, the numerical code corresponding to the closed numerical key is
At the same time as being stored in the first digit of RAM1S, the number is displayed at the cursor position on the display device 4, and the cursor is shifted to the next digit. And the number keys,
While waiting for the "STORE key" and "CLEAR key" operations, a determination is made as to whether the number stored in RAM1S has reached 16 digits. When a numeric key is closed, the numeric code is sequentially stored in RAM1S,
Numbers are displayed on the display device 4. When the number reaches 16 digits, the closing of the numeric key is not detected and inputting of the numeric key is stopped. In this way, the telephone number is stored in RAM1S. Here, when the "STORE key" is closed, the address specifying means 11 specifies the address of RAM2S paired with RAM2A in which the character code was previously stored, and sequentially stores the numerical code of RAM1S in that RAM2S. After that, the character flag FLG is reset, RAM1(7) and display device 4 are cleared, and the process returns to AA in FIG.
Therefore, the phone number is stored in RAM2S. On the other hand, if the "CLEAR key" is closed during operation of the numeric keys, RAM1(7) and display device 4
is cleared.

Through the operations described above, the name and telephone number are stored as a pair in the RAM2(9).

Next, the search mode will be described. As shown in FIG. 4, when the "SEARCH key" is closed after entering three or more characters, the search mode shown in FIG. 6 is entered. When the search mode is entered, the search means 13 operates, the addressing means 11 is controlled, and the top three stored in the RAM 1A are
The characters are stored in the search means 13. At this time, the addressing means 11 sequentially specifies the addresses of all RAM2A, and the upper three characters of each RAM2A are
A match with the three characters taken out to the RAM 1A and stored in the search means 13 is detected. As a result of the search,
If there is no matching name, display the words "NOT FOUND" on the display device 4, and then clear RAM1 (7) and the display device 4 by closing the "CLEAR key" and Return to AA in Figure 3. When a matching name is found, the starting address of the RAM 2A where the name is stored (if there are multiple matching names, all of the starting addresses) is stored in the address specifying means 11. Then, the address specifying means 11 specifies the RAM2A specified by the smallest starting address, and transfers the 16-character character code stored there to the RAM1A. Further, the characters are displayed on the display device 4. Then, “PAGE key” and “NUMBER key”
The system waits for the “DIAL key” and “CLEAR key” operations. When the "PAGE key" is closed, the addressing means 11 addresses RAM2A specified by the next stored first address, transfers the 16-character character code stored there to RAM1A, and , causes the display device 4 to display the character.
Therefore, by operating the "PAGE key", matching names, etc. are displayed in sequence. In this case, if there is only one matching name, the display will not change even if the "PAGE key" is operated because there is only one stored starting address. When the "CLEAR key" is closed for some reason, such as because the desired name is not found, RAM1(7) and display device 4 are cleared.
Return to AA.

On the other hand, when the "NUMBER key" is closed, the address specifying means 11, which stores the first address from which the character currently displayed is read out, specifies the first address paired with the first address. By addressing the RAM2S, the numerical code stored in the RAM2S is transferred to the RAM1S, and the numerical code is displayed on the display device 4. That is, the stored telephone number is displayed in pair with the name displayed by the "NUMBER key". Then, it waits for the "DIAL key" and "CLEAR key" to be operated, and when the "DIAL key" is closed, the numeric code stored in the RAM1S is sequentially sent to the acoustic signal generation means 2 from the upper digit every second. The sound generator 1 generates a sound having a frequency corresponding to the number, and the corresponding number on the display device 4 flashes to clearly indicate the number being sounded. This operation causes the telephone number to be sent. On the other hand, “CLEAR key”
is closed, the phone number is displayed but no sound is generated, and RAM1(7) and display device 4
Clear and return to AA in Figure 3.

On the other hand, when displaying the name etc. searched by the "SEARCH key" and "PAGE key",
When the "DIAL key" is closed, the name is paired with the name displayed at that time, as described above.
The RAM2S is addressed by the addressing means 11, and the numerical code stored in the RAM2S is
While being transferred to the RAM1S, the number is displayed on the display device 4, and further, the number code is sequentially sent from the upper digits of the RAM1S to the audio signal generation means 2, and the telephone number is sent out. Of course, the number being sounded is clearly indicated by flashing on the display device 4. When the transmission is completed, RAM1(7) and display device 4 are cleared and the process returns to AA in FIG. That is,
In this case, the telephone number is sent directly from the name, etc., without confirming the telephone number.

In this way, the search means 13 operated by the "SEARCH key" searches for similar names by detecting a match between the three input characters and the first three characters of RAM2A, and searches for similar names, etc. by pressing the "PAGE key". ” The names etc. retrieved by the search can be displayed in order, so
You can easily search for the desired name.
Then, you can send out that phone number by pressing the "DIAL key".

(e) Effects As described above, the automatic dialing device of the present invention has a first memory for one address, which has first and second areas that store a name and a telephone number inputted by a function key as a pair. means and said first
a second storage means provided with a plurality of pairs of first and second areas for storing names and telephone numbers stored in the storage means as pairs; Since the telephone number and name stored in the storage means are displayed on the display device, the entered name and telephone number can be checked before being stored in the second storage means, and the memorization is ensured. Ru.

Also, when searching, input the first letter of the name to be searched into the first storage means, and the search means detects a match with the first letter of the name stored in the second storage means, and when a match is detected. The entire first area of the corresponding address stored in the second storage means is held in the addressing means, and the function key is
The first address specified by the address held in the address specifying means by operating the PAGE key.
The names stored in the area 1 are sequentially read out into the storage means 1 and displayed on the display device, and when the name to be searched is displayed, the telephone number paired with the name is inputted by operating the numeric keys. Since the information is read into the first storage means and displayed on the display device, the telephone number can be searched quickly.
