Abstract

PURPOSE:To facilitate retrieval of destination and dialing operation by comparing the information of a character area and a mode area stored in a storage section with the information inputted by a key input means, retrieving the result and using a dialing circuit so as to dial a destination number stored in a numerical area. CONSTITUTION:A character such as Japanese syllabary or a symbol is inputted by a dial key, a code corresponding to each character in the Japanese syllabary order is added, the destination information consists of a character area representing the name of destination, a mode area representing whether or not the registration is kept secret and a numeric area representing the telephone number of the destination, a registration control section 16 discriminates the arrangement of the character in the character area and stores the result to a memory section 28. In retrieving the character, the character is retrieved by a retrieval control section 18 sequentially from the 1st character of the destination while the quantity of a code number is compared and the result is displayed on a display means. Thus, the destination is inputted simply on a dial key such as a telephone set by depressing the same key once or plural number of times so as to attain retrieval.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention stores a plurality of telephone and facsimile numbers and names of destinations as one unit, and when calling a destination, can arbitrarily search and dial the number. The present invention relates to a destination number storage device that can store destination numbers.

[Conventional technology] When making a dial call or facsimile call to a destination, use a notepad with the destination name and number written on it, find the destination name, and visually check the corresponding phone number. dialing (this will be referred to as the first method).

As a method to prevent erroneous dialing that often occurs when dialing and to enable quick searching, one push button is associated with each destination, and the destination number is stored in the device, and the destination name is written near the push button. There is a dial device that allows you to dial with one touch by opening the button and pressing the button (this is called the second method).
.

A large number of destination names and numbers can be stored. Names and numbers can be registered together in the device's internal memory, and when searching, you can enter the destination name and find a registered name that matches the entered destination. In such cases, there is a device that can shorten the search time by calling the registered telephone number of the destination together with the name (this is called the third means).

[Problems to be Solved by the Invention] In the first method, erroneous dialing is likely to occur when the number has a large number of digits, such as an area code. Additionally, destination names are generally entered in the alphabetical order, and it is not always possible to write a new name in the blank space in the alphabetical order, and the more destinations are added, the more the writing order becomes disrupted. There was a problem in that searching was difficult.

In the second method, the number of destinations that can be registered is 20.
There is a problem in that, in order to always organize the information in the alphabetical order, there is a problem in that it involves many complicated operations such as new registration, deletion, and sorting. Therefore, it was not suitable for storing a large number of destination numbers.

The third method allows a large number of destination numbers to be stored and can be searched in a short time; however, when performing this search, the name of the destination that is exactly the same as the registered name must be entered. There was a problem in that the operator had to remember the destination name accurately.

[Means for Solving the Problems] The present invention was made to solve these problems.Characters and symbols such as the 50 syllabary characters are input using dial keys, and each character corresponds to the 50 syllabary order. The destination information includes a character area that represents the name of the destination, a mode area that indicates whether or not the registration is to be kept secret, and the phone number (or) of the destination. The first character of the destination name is stored in the storage means in alphabetical order based on the arrangement of the characters in the character region by the registration control means. The search means sequentially performs a search while comparing the size of the code numbers, and displays the results on the display means.

[Operation] When searching for an address, the code number of the first character of the address is given the greatest weight, and if there is a code number that is the same as the code number of the first character entered for the search, the code number of the first character of the address is given the highest weight. The search control unit operates to compare the code numbers of the second character and, if there is no code number that is the same as the code number of the first character, to search for a code number with a larger code number.

In the secret search, if there are many stored addresses that have the same code numbers for all characters of the input address, that code is displayed on the display means.

Addresses can be easily entered and searched by pressing the same key once or multiple times using the dial keys of a telephone or the like. Therefore, even if a personal address is stored, it can be retrieved within a short time.

[First Embodiment] FIG. 1 shows the configuration of a first embodiment of the present invention, which will be described below. Here, KO is a key input section, which includes a dial key 110, etc., and its appearance is shown in FIG.

The internal configuration of the storage unit 28 is shown in FIG. 2 and will be described.

FIG. 2(a) shows the position of memory row Y where information including the destination name and telephone number (hereinafter referred to as destination information) is stored, and the leftmost number is the memory row Y.
The address (position) number O to n is shown.

Figure 2(b) shows the detailed contents of one memory row from O to n-1 of memory row Y, so the numbers on the right end are the address numbers of memory column X, from O to m. It shows.

The a-1st addresses from the O address of the memory string The range up to mth is r<li2<hereinafter referred to as numeric area) for storing telephone numbers.

FIG. 2C shows the detailed contents of the n-th memory row Y, indicating the memory column X. The stored information of the n-th item is different from the contents of the 0th to (n-1st) items (FIG. 2(b)). The 0th to m-3th memory rows store codes that are predetermined information, and the m-th rows of the memory row to Y-n-1Q, the number of memory rows is 10.) is stored.

In the embodiment of the present invention, the registration starts from the n-1st memory row Y and sequentially n-2, n-3...2,1
゜0, and the mth of the memory column X in FIG. If up to -10 is stored, 5Y=n-10) is stored. Therefore, whether there is a memory row remainder (margin) is determined by the second
All you need to know is whether the m-th content SY in figure (C) is O (the remainder in the above case is Y-0 to Y-rl-1
This is n-10 rows up to 1. ) With this configuration, the same control method can be used even if the capacity of the storage section is different. However, it is also possible to use a configuration in which number n in FIG. 2(a) is set to number 0, and registration starts from the first row and there are no remaining memory rows when 5y-n is reached.

The m-2nd and m-1st in FIG. 2(c) represent the total number of memory columns X in the memory row Y that are still blank spaces. The first address of the first memory row number SY, that is, the address 0 (X-0) of the memory column X, 5YH-3YL-3Y
X (m+1) is stored. Here m+1 is memory row Y
is the number of memory columns X included in one address of This is because 5YH-3YL stored in SY is m+1 times as large as SY, so it becomes a large number and needs to be stored separately into upper and lower digits.

FIG. 3A is a functional mechanism diagram for explaining the operation in which the mode starting unit 14 learns the state of the storage unit 28 immediately before starting the registration 1] control unit 16 and search control unit 18 and initializes it to an appropriate state. FIG. 3B is a flowchart showing the details of the operation.

In FIG. 3A, 140 is a sign comparison control unit included in the mode starting unit 14 that performs control according to the flowchart shown in FIG. 3B, and 141 is a register (register contents is A>, 143 is a register for temporarily storing information read from the fixed data storage section 144 (the contents of the register is B>, 142 is a register 141 and register 14)
A comparator 144 which compares A and B, which are the contents of 3, and outputs whether they are equal to 1 or not, stores predetermined fixed data, that is, the signs from C8 to Cl1l-3 in FIG. 2(C). The fixed data storage section 68a is
146 is a part of the transmission path 68 shown in the figure and is an address selection information transmission path to the storage unit 28; 146 is a transmission path that transmits the same information as the transmission path 68a to the fixed data storage unit 144;
Reference numeral 68b is a part of the transmission path 68 shown in FIG. It is a transmission channel.

FIG. 3B explains the recognition operation for checking the storage state of the storage unit 2B in an initial state where no destination information is registered in the storage unit 28.

46 corresponds to the transmission path 64a, the transmission path 68b corresponds to the transmission path 68d, and the transmission 1148 corresponds to the transmission path 64b. Here, the transmission paths 68C and 68d form part of the transmission path 68 in FIG. 1, and the transmission paths 64a and 64b form part of the transmission path 64 in FIG. However, in Figures 3 and B, the object of comparison was the symbol to be initialized (Figure 2 (C)), whereas the comparing unit 20 compared the characters 1o, (from Y=O to Y-n-1 The difference is that the comparison targets are the mode range (from X=O to X=a-1) and the mode range <X=a).

The details of the operation of the comparator 20 when searching for a destination name will be explained with reference to FIG. 4B. First, by setting X=a and Y-3Y (STEP 211), characters in the mode area of the first storage line are compared (see FIG. 2). That is, the contents M of the mode area of the storage unit 28 are stored in the register 20'l (S

It is smaller and located at a younger address.>, the comparison Luli @ section 200 stops the comparison operation, sets the above-mentioned EQ to O, and outputs 5TEP226>, along with the storage row address Y.

FIG. 5A shows an output circuit for a dial signal that is output when the execution key 109 (FIG. 7) is pressed after the search is completed, and FIG.
It is a figure which shows the relationship between a number code and a dial code. In FIG. 5A, the dial output section 30 inputs the telephone number (number area) received from the search control section 18 to X-a+1.

While converting the numerical code shown in the figure into a dial code, the optically coupled phototransistors 402a to 402g are turned on or off via the light emitting diodes 403a to 403CJ. Here, if the dial code in FIG. 11 is O, it is turned on, and if it is 1, it is turned off. Further, codes other than the numerical codes shown in FIG. 11 (for example, blanks) are ignored and not output.

On the other hand, a general telephone has a configuration as shown in Figure 5B, and when the hook switch is OFF, it emits a ring tone and rings 1Q when the hook switch is OFF.
When you are in L/, you can make phone calls and also make dial calls. Dial key 110G

In many cases, it operates in va) in the figure. In this case, a separate power supply (5a
In order to transmit a dial signal from a circuit operating in FIG. Therefore, in the embodiment of the present invention, a photocoupler is used to transmit signals. However, if insulation is not required, the photocoupler may be replaced with a simple transistor. Furthermore, even if the N source VB is not supplied to the destination number storage device, dialing must be possible, so as shown in Figure 5A, a dial key signal is directly input in parallel with the output of the photocoupler. The dial key 110 has a double contact so that it is connected to the transmission circuit 401 and not electrically connected to the key detection section 12. Further, a dial prohibition output unit 32 controls so that a dial signal is not output at the time of registration or search. As is clear from FIGS. 5A and 5B, the destination number storage device according to the present invention can easily be incorporated into a telephone since it replaces the dial key 110 of FIG. 5B.

FIG. 5C shows a device in which the destination number storage device 45 according to the present invention is not built into a telephone but is built into an independent dialing device 46, and which only makes dialing by switching the telephone line using switching contacts 47a and 47b. It shows that it can be used as

FIG. 6 shows the display positional relationship of characters or numbers when the display selection section 36 switches the contents of the temporary storage section 34 and transmits them to the display section 38. The address structure of the temporary storage section 34 is exactly the same as shown in FIG. 2(b). The mode area is divided into a display mode area and a comparison mode area (
(Hereinafter, when we simply refer to the mode area, we will refer to the mode area for comparison.) Note that although the display section in FIG. 6 has one row in the horizontal direction, it may be constructed of two or more rows.

FIG. 10A is a character table in which dial key input and a counter mz for the number of presses of the same key, which will be described later, are used as factors. In addition to katakana characters, some symbols are also assigned for convenience when creating destination names, and in particular, characters can be erased by pressing the dial key "*" once (Z-1). or, in the case of Z-6, the dial.
Except for cases where the key is "4", "Bn, or t"*", alphabetic characters are assigned and prepared as symbols so that even if the destination names are the same, they can be distinguished. This is convenient when a person has multiple telephone numbers.Character codes for katakana characters and some symbols are shown in Figure 10B, but the character codes for characters not listed in Figure 10B are 8 units of JISC6220. Character codes are given according to the code table.If characters are input using this method, the number of character types can be increased without limit by making the maximum value of Z larger than 6.
This will be clear from Figure 0A.

The main parts have been explained above with reference to the drawings, and the registration operation and search operation according to the present invention will be described in detail.

Registration operation When the registration key 107 (FIG. 7) of the key input unit 10 is pressed, the information is transmitted to the mode activation unit 14 via the key detection unit 12 in FIG. After performing a recognition operation to confirm the information, the registration control unit 16 is activated.

The registration control unit 16 first writes blanks (character code 20 (Figure 10B)) to all addresses (from x-〇 to x-m) in the temporary storage unit 34, and then changes the comparison mode of the temporary storage unit 34. The character "T" is written in the area and the display mode area (FIG. 6) (hereinafter, this operation is referred to as registration initialization). The letter "T" is used only to identify the mode and may be any other symbol or letter. Furthermore, the characters for display and comparison do not need to be the same. If the secret key 106 (meaning secret, Fig. 7) is pressed during the registration operation, the above ``d'' is changed to ``t'' to indicate secret registration.Here, ``t'' is also changed to ``T''. Characters or symbols of similar function may be used.

The registration control unit 16 instructs the display selection unit 36 to initially display the character area, so the display 101 (FIG. 7) included in the display unit 38 displays a display like T1 shown in FIG. 8. Further, the registration control unit 16 sets X=0 (see FIG. 6) after the registration initialization is completed, so that the cursor is displayed at the leftmost position. Here, the cursor is transmitted to the display unit 38 through the X transmission path 64 and is always displayed at the position designated by X.

Next, the registration control unit 16 selects the right shift key 103 (seventh
) is pressed, add 1 to X and left shift key 102 (
7) is pressed, subtract 1 from X. However, X
Once it reaches -O, no further subtraction is performed. Also, X-m
Once this happens, no further additions are made (see Figure 6).

Further, when the dial key 110 is pressed, if it is the same as the previously pressed key, the value Z (10th A (see figure, hereinafter simply referred to as Z) is increased by one. However, if it becomes Z-7, it is set as Z-0. Roughly speaking, Z is set to Z-0 when shift keys 102 and 103 are pressed and X changes, or when a different type of dial key is pressed. The character code is the value of the dial key and the value of 2.The control unit 16 registers the value of the dial key and the value of 2.
4, and the character conversion unit 24 is obtained by passing it to No. 10A.
The characters according to the character table shown in the figure are converted into character codes shown in FIG. 10B and returned to the registration control section 16. Since the registration control unit 16 automatically stores the received character code in the position of
It is updated each time 10 is pressed, but if X changes, the character entered immediately before will remain as is.

T2 to T11 in FIG. 8 are specific examples of inputting "Ishikawa" (the left side shows the input key, and the right side shows the displayed state).

Next, the operation when inputting numbers (telephone numbers) will be explained. When the right shift key 103 is pressed multiple times to reach X-a, the registration control section 4 instructs the display selection section 36 to set X to X-a+1 and to set the display area to the numeric area. The changes in the display contents on the display 101 during this time are shown at T1 in FIG.
1 to T13. When the left shift key 102 is pressed and the value changes from X-a+1 to X-a, the registration control unit 16 instructs the display selection unit 36 to set the display area to the text area as X@X-a-1. The above-mentioned character input becomes possible again. Next, after the registration control unit 16 becomes X-a+1, the input dial key 110 is converted to the numerical code shown in FIG. The numeric conversion unit 26 returns the corresponding numeric code to the registration control unit 16, so write that numeric code in the position indicated by X in the temporary storage unit 34, and then press the shift key 102 or 103.
Increase X by 1 regardless of . Here, since there is a 1:1 correspondence between the numbers and the dial key 110, there is no need to hold X as in inputting in the character area. The situation during this time is shown from T14 to T16 in FIG. After inputting the destination information, press the execution key 109 (FIG. 7) to store (register) the destination information in the storage unit 28.
be done.

Furthermore, a storage operation for storing data in the storage unit 28 in alphabetical order will be explained. The registration control unit 16 instructs the comparison unit 20 to compare the character area contents and mode area contents of the temporary storage unit 34 with the character area contents and mode area contents of all the storage lines in the storage unit 28 ( 4A, 4B). The comparison unit 20 compares the two as described above, and if the character area and mode area are equal, it is EQ-1 and 5TEP2.
29), if not equal, set EQ-0 and 5TEP21
7.226), is output together with the value Y of the storage line. The registration control unit 16 passes the output to the organizing unit 23. If EQ=1, the organizer 23 makes the content M of the memory line indicated by Y equal to the content (X, Y)'' (X) of the temporary memory unit 34, and then notifies the registration control unit 16 that the process has been completed. , and if it is EQ-0, the memory rows from SY to Y-1 shown in FIG.
(x, sy> 1M M(X, SV) (x, sy+1) 1M 1M M(x, y-2) Move the contents of the storage unit 28 as (X, '/-1> (X is O ), then move the content T of the temporary storage unit 34 to M(i-1), leaving M(X) (X, V) (x, n-1) as before, Next, subtract 1 from the value of SY in Figure 2 (C) from M to create a new SY, and subtract m+1 from 5YH-3YL to 5YH-3Y.
L, and then notifies the registration control unit 16 that the registration has been completed. The registration control unit 16 then returns control to the mode activation unit 14.

As described above, since the destination information is registered in alphabetical order (code order in FIG. 10B) for all character areas with the same mode area, searching becomes easy.

Although the above description has been made regarding the case where the destination name is expressed in katakana, it is also possible to display it in Roman letters by assigning English letters to each dial key instead of the one shown in FIG. 10A. In this case, the character code is JIS
If defined according to the C6220 8-unit code table,
The contents of the storage section 2B will be arranged in ABC order.

- In the case of a normal search, only the destination information registered without pressing the secret key 106 (Fig. 7) at the time of registration (those whose mode area is "T et") is searched. There are two cases: a secret search, that is, a search for destination information registered after pressing the secret key 106 at the time of registration (those whose mode area is "t").These two cases will be explained below. , as a specific example, is assumed to have already been registered in the storage unit 28 as shown in FIG. 9A.First, the normal search will be explained with reference to FIG. 9B.

When the search key 108 (FIG. 7) is pressed, the mode activation section 14 operates as described above and issues the search activation signal 50.

The search control unit 18 transfers the contents of the storage line indicated by SY in FIG. 1.At this time, the display mode area is marked with “K” to distinguish it from the registration (Fig. 8).
'' and the cursor is not displayed. Also, the mode area is set to "t". The destination information displayed immediately after pressing the search key 108 is not the information in the memory line indicated by SY as in this case, but other information. It may be information of

Next, select one of the dial keys 110, for example “
When 2'' is pressed, the search control unit 18 sends the key information and 2 (10A
), receives the code for the character “Hippo” from the character conversion unit 24, and stores it in the transmission path 64 at the position of X=0 in the temporary storage unit 34.
Write via. Characters in positions X-1 to X-a-1 are not to be compared, so blanks are written. Therefore, the display 101 displays as 2 in FIG. 98.

Next, the search control unit 18 instructs the comparison unit 20 to perform a comparison. The comparison unit 20 compares the first storage row address SY (9th
In the case of figure A, from 5Y-n-10> to the final memory row address Y-
The comparison is repeated up to n-1 until the contents of the character area and mode area match or become larger than those in the temporary storage section 34, and as a result, EQ and Y are output. 9th B
In the case of the specific example explained in the figure, “force′° is “
The value of the code shown in Figure 108 is larger than the first character "I" of "Ishikawa", and when compared with "Rikika" in Figure 9B, it is the first character.
Since the characters are equal, the second character is compared, and since the second character in the temporary storage section 34 is a blank, this blank and the second character of "Holi" are compared.
When the characters are compared, since the code value of the second character of ``kaka'' is larger, it is determined that ``force'' is smaller than ``force force'', and the comparison unit 20 calculates EQ=O, Y=n. Outputs -9. Next, the retrieval unit 111 transfers the contents of Y=n-9 to the temporary storage unit 34 and specifies the display area as the character area, so the display unit 61 displays as shown in 3 in FIG. 9B. Ru.

Similarly, if you enter the dial key "5", the 9th B
The first character to be searched for is displayed as shown in Figure 4 (Figure 10A), followed by the first character (name) whose code value is larger than ``su'' and which is the content of the closest character range. 9A
Y-n-3) in the figure is displayed as 5 in Figure 9b. When the up scroll key 104 is pressed, the search control unit 18 subtracts 1 from the value of Y at that time. For example, in the specific example, the value of Y at that time is ¥-n-3, so the contents of the n-4th memory row are stored in the temporary storage section 34 as a new Y-(n-3) -1=N-4. Transcribe.

At that time, the display on the display 101 becomes 6 in the 9th BIk. Similarly, when the up scroll key 104 is pressed again, the screen becomes as shown in 7 in FIG. 9B.

The search control unit 1B includes a portion (hereinafter referred to as a mode area temporary storage unit) which always has the same content as the comparison mode area of the temporary storage unit 34 and temporarily stores the same content. If the mode area indicating whether the destination information read from the storage unit 2B is a iris search or a secret search is different from the content of the mode area temporary storage unit included in the search control unit 18, the search control unit 18 Do not update Y. In other words, if the scroll key 104 or 105 is pressed to increase or decrease the value of Y, or if the mode area character changes (meaning the point at which it no longer matches the contents of the mode area temporary storage unit), Do not increase or decrease the value of Y any further. Therefore, when the mode range changes from ``T'' to t'' in Figure 9A, the value of Y is not increased any further, and the secretly registered part will not become the search output (the mode range character Also JIS C
The group whose mode line is “Top” and the group whose mode line is “111” are ranked and registered according to the 8-unit code table of
groups are formed separately at the time of registration. If secret registration is not done, scroll key 104 or 105
The range in which the value of Y can be increased or decreased is from Y-3Y (9th
In the case of diagram A, the range is from 5Y-n-10) to Y-n-1.

Here, a case in which only one key of the dial keys 110 is pressed multiple times will be described in detail. For example, pressing the dial key "2" will display the number 8 in FIG. 9B, as described above. Next, press the dial key “′” again.
When ``2'' is pressed, Z in Figure 10A becomes Z-2, so ``key'' is placed in X-O of the temporary storage section 34 and comparison is started, but the character area starting with ``key'' is in Figure 9A. Because it is not in
"Key" is also a character area starting with "7" with a large code value (Y-n-6> is the output of the comparison unit 20, and the 9th B
It will be displayed like 9 in the figure. Dial in quick succession.
When key "2" is pressed, 7 in Figure 10A becomes 3'
The character area starting with ``ri'' is placed at X-0 of the temporary storage section 34 and the comparison is started.Since the character area starting with ``ri'' has already been displayed, the display does not change as shown in 10 of FIG. 9B. When the dial key "2" is pressed, Z in FIG. 10A changes to 4, and the "key" is placed at X-0 in the temporary storage section 34, and comparison is started (Y-n-5 < FIG. 9A). The destination information is searched and the result is displayed as shown in 11 in FIG. 9B.

After searching for the desired destination name using the operation method described above,
When the execution key 109 is pressed, the search control unit 18 passes only the numeric area of the temporary storage unit 34 to the dial output unit 30. Thereafter, the dial code shown in FIG. 11 is output from the dial output unit 30 as described above, and when the dial code is completed, the search control unit 18 is notified of this, so the search control unit 18 outputs the dial code shown in FIG. 11 as shown in FIG. After displaying the numeric area so that the operator can confirm the number, control is returned to the mode starting section 14.

Next, the case of secret search will be explained using FIG. 9C.

When the search key 108 (FIG. 7) is pressed, 1 is displayed in FIG. 9C in the same manner as in the normal search. Next, when the secret key 106 (FIG. 7) is pressed, the search control unit 1B knows that the search is a secret search, and changes the display as shown in FIG. 9C, 2. In other words, after all the contents of the temporary storage unit 34 are set to blank characters, the text "kH" indicating that it is a secret search is written in the display mode line and "1pa" is written in the comparison mode area. Then, it waits for an input.The input method is exactly the same as that described for the registration operation, and is performed using the dial key 110 and the shift key 102.i03.

In FIG. 9C, from 3 to 15, the case is explained in which the character Xg is entered and ゛kensakupa is entered in (destination name).

When the input is completed in this way, the secret key 106 is pressed twice in order to notify the search control section 18 that the input is completed, and the search control section 18 stores the contents of the character area in the temporary storage section 7 and the characters in the storage section 28. Instruct the comparator 20 to compare the contents of Iti and the mode area, check the output EQ of the comparator 20 obtained as a result, and if EQ=1 is found, the content of the address indicated by the output Y of the comparator 20 is transferred to the temporary storage section 34.

That is, the display 61 displays the information as shown in 16 in FIG. 9C. In the case of EQ=O, there is nothing applicable, so
A warning is generated, but the contents of the temporary storage section 34 are not changed.

The operation of the search υj control unit 18 after the secret search is completed is the same as in the normal search. As is clear from the above explanation,
In secret search, encryption is easy because the search output is not output unless all the characters in the character area match.

That is, the number of combinations is 50 (a-1) Togoku, assuming 50 katakana characters, and it is almost impossible to search unless you have memorized them. Even if a secretly registered destination name is easy for the person who registered it to recite (for example, the name of the destination), it is not easy for a third party to find it, so the person who registered it may also forget the recitation. number (number)
This is superior to the traditional method that uses

[Second Embodiment] The first embodiment of the present invention has been described above, but with reference to FIG. This will be explained with reference to FIG.

FIG. 12 shows only the parts of FIG. 1 that have been changed to realize the second embodiment.

However, the key input section 10, the display section 38, the display selection section 36,
The temporary storage section 34 is the same as that shown in FIG. Input key information transmitted from the key input section 10 through the transmission path 61 is sent to the transmitting section 81, the transmission line 82, and the receiving section 83.
The input key information is transmitted as input key information to the mode activation section 14 of the destination number storage device, etc. through the transmission means comprised of the following. The subsequent operation of the telephone number storage device is the same as that in the first embodiment. On the other hand, the contents written in the temporary storage section 34 are passed through the display selection section 36, and the value of
8 and is transmitted to the display section 38 through a transmission means composed of a transmitting section 88, a transmission line 87, and a receiving section 86.

72a is a transmission path for transmitting character or numeric information, and 64C is a transmission path for transmitting the value of X.

Specifically, this second embodiment may be applied to a button telephone device, etc.;
Generally, the dial generator is often located within the main device that performs overall control, and the destination number storage device according to the present invention may also be located within the main device. Further, in the button telephone device, press information on dial keys or control keys is transmitted from the terminal telephone to the main device via a transmission path, and display information is transmitted from the main device to the terminal telephone via the transmission path. Therefore, in order to realize the second embodiment of the present invention, there is no need to newly provide a transmitting section, a transmission path, and a receiving section, and the control key required by the destination number storage device according to the present invention is included in the input key information. In addition to the information specific to the button telephone device, the information input to the storage section described above is added to the displayed information and transmitted, and the display information is also used as an intermediary for the control section originally built in the button telephone device. All you have to do is receive the information. Also,
When making a dial call, a dial prohibition output and a dial code are passed from the destination number storage device to a control section built in the button telephone device, thereby making the dial call. In this case, the dialing code does not have to be the dialing code shown in FIG.
It may be a zero-encoded binary code.

[Third Embodiment] It is also possible to incorporate the destination number storage device of the present invention into a button telephone device. In a button telephone device, generally a plurality of terminal telephones are connected. That is, the transmission means shown in FIG. 12 is divided into multiple stages using a time-division method or a space-division method, and has a plurality of display sections or key input sections. in this case,
Since individual terminal telephones tend to be used exclusively for personal use, the destination information to be registered is also different for each terminal, and it is desirable that the information does not interfere with each other. In other words, it is sufficient to secure a storage area corresponding to each terminal telephone. but,
Fixing the storage area is not efficient when there is variation in the amount of individual registrations, so write it down according to the amount of registrations.
It is desirable that the @bandit is variable.

The third embodiment takes this point into consideration, and this embodiment will be described below.

Regarding the registration operation or the search operation, as described above, the comparison unit 20 compares characters with priority given to characters in the mode area. Therefore, the secretly registered destination information could not be output from the comparator 20 unless a secret search was performed, but similarly, identification characters for secret search or mode display (for example, “T Pl , “t
If you enter a character other than `` or >, a group will be created using the input character as an index, and within the group, the destination names can be arranged in alphabetical order. Terminal phones are also numbered, so we decided to decide on a character corresponding to that number and write that character in the mode area when the terminal phone is used for registration or search. There is no particular change in the search operation when the scroll key is pressed, and the contents of the mode area temporary storage section included in the search control section ] 8 can be rewritten to the above characters corresponding to the terminal phone. If you set it to
", K", "k"), and the mode area characters stored at the time of registration are unique to the terminal telephone. However, in the case of secret registration or secret search, the mode area character is "t Tl" regardless of the terminal telephone.

[Effects of the Invention] As explained above, according to the present invention, the number of operation keys can be reduced because the dial keys are used for registration, and by pressing the same key multiple times, the characters in each line of the syllabary can be changed. Since they are displayed sequentially, you can easily select characters without having to think about operations, and there is no limit to the number of characters in each line of the 50 syllabary characters, and lowercase katakana characters can also be provided, making it easy to express destination names. This allows for greater flexibility, and since English characters are also provided, it is possible to distinguish and register destination information that has the same name and multiple telephone numbers. In addition, by using the mode area, you can register an unlimited number of destination information that you want to keep private, and by registering it in major categories, one of the major categories can be used as a personal telephone number list. This allows flexibility in usage.

When searching, you can search for the destination name simply by pressing the same dial key that corresponds to each row of the 50/50 sound chart once or multiple times, and you can use the scroll keys to search the entire range, so there are no keys to operate. Only one kind is needed.

After searching, you can simply press the execution key to make a dial call, so there is no risk of making a mistake. In the display method, since the display is divided into a character area and a mode area, both power consumption and material costs are reduced. In other words, when destination information is composed of a destination name and a telephone number as in the present invention, there is no need to display the destination name because it is the object of the search and the telephone number is optional. , Therefore, the display area can be halved and the display material cost can also be halved.

Furthermore, in the mode display, it is sufficient to distinguish between registration mode, secret registration mode, normal search mode, and secret search mode by using letters in the mode area without using a light emitting diode or the like. Therefore, if a liquid crystal display or the like is used as the display means, power consumption can be extremely reduced. In addition to the above-mentioned telephones, dial (dedicated) transmitting devices, and key telephone devices, the present invention can be applied to all devices having a dial transmitting function, such as facsimile machines that communicate using telephone lines.
