Description

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

[Prior art] When making a dial call or facsimile call to a destination, use a memo pad with the name and number of the destination written on it to find the name of the destination.
The user dials the corresponding telephone number while visually checking the number (this is called 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 dialing device that allows one-touch dialing by pressing the button (this is called the second means).

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 means, erroneous dialing is likely to occur in the case of a number with a large number of digits, such as an area code. In addition, destination names are generally entered in alphabetical order, and it is not always possible to write a new name in the blank space in alphabetical order, and the more destinations are added, the more the writing order becomes disrupted. There was a problem that it was difficult to search.

In the second method, the number of destinations that can be registered is limited to about 20, and in order to always organize them in alphabetical order, many complicated operations such as new registration, deletion, and rearranging are necessary. There was a problem with this. Therefore, it was not suitable for storing a large number of destination numbers.

The third method allows you to store a large number of destination numbers and to search for them in a short time; however, when performing this search, you must enter the name of the destination that is exactly the same as the registered name. There was a problem in that the operator had to remember the destination name accurately.

[Means for Solving the Problems] The present invention has been made to solve these problems.Characters and symbols such as the 50 syllabary characters are input using a dial key, and each character corresponds to the 50 syllabary order. The destination information consists of a character area that represents the recipient's name, a mode area that indicates whether the registration is to be kept secret, and a numeric area that represents the recipient's telephone number (or facsimile number, etc.). The code numbers are stored in the storage means in alphabetical order according to the arrangement of characters in the character area by the registration control means, and when searching these, the magnitude of the code number is compared starting from the first character of the destination name. While doing so, the search means sequentially performs a search, and the results are displayed 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 latest code number of the first character entered for the search, 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 large number of addresses are stored, they can be retrieved in a short time.

The numbers at the right end indicate the address numbers of the storage column X, 0 to m. Addresses 0 to a-1 of memory string
The area from th to mth is an area for storing telephone numbers (hereinafter referred to as numeric area).

Figure 2c is the nth detailed content of memory row Y,
This shows a storage column X. The stored information of the n-th memory is different from the contents of the 0th to (n-1)th memory (FIG. 2b). From the 0th to the m-3rd of the memory column −
If 1 to Y=n-10 are stored, the number of memory rows is 10. ) is memorized. In the embodiment of the present invention, the registration is arranged such that the memory row Y starts from the n-1st row and proceeds sequentially to the n-2nd, n-3th, . . . 2nd, 1st, 0th row, as shown in FIG. m of memory sequence X
The first storage row number SY (the youngest number, for example, SY=n-10 if Y=n-1 to Y=n-10 are stored) is stored in the th column. Therefore, to determine whether there is a memory row remainder (margin), it is sufficient to know whether the m-th content SY in Figure 2 c is 0 (the remainder in the above case is Y = 0).
This is n-10 rows from Y=n-11. ) With this configuration, the same control method can be used even if the capacities of the storage sections are different. but,
It is also possible to set the number n in FIG. 2a to 0, and the registration starts from the first, and when SY=n, there are no more memory rows left.

The m-2nd and m-1st in FIG. 2c represent the total number of memory columns X in the memory row Y that are still blank spaces. The first address of the first storage row number SY, that is, the address No. 0 (X=0) of the storage column X, SYH·SYL=SY×(m+1), is stored.
Here, m+1 is the number of memory columns and stored in number m-2
This is because SYH and SYL are m+1 times as large as SY, so they are large numbers and must be stored separately into upper and lower digits.

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

First, as Y=n and X=0, 0 in Figure 2c
Initial setting to indicate the number (STEP 15)
1, STEP 152). Here, the address of the storage unit 28 of the sign to be read is calculated using the formula YH・YL=Y×(m
+1) Calculate according to +X. Here, YH indicates the upper address of the storage section 28, and YL indicates the lower address.
For example, when reading the contents stored at address 2 in FIG. It represents the number (address) of storage columns from =0, X=0 to Y=n, X=2. Next, the read addresses YH and YL are outputted to the storage unit 28 through the transmission path 68a, and the memory contents at those addresses are output.
Load M _(X,Y) into register 141 (STEP 15)
3). Next, the contents of the address indicated by X from the fixed data storage unit 144 C _(X) , that is, the fixed data C ₍₀₎ = C ₀ ,
C ₍₁₎ = C ₁ , C ₍₂₎ = C ₂ , ..., C _(n-3) = C _n-3 are taken into the register 143 (STEP 154). Next, the comparator 142 compares the contents A of the register 141 and the contents B of the register 143 (STEP 155), and if the result is A=B, 1 is added to X (STEP 15).
6), and if X is less than or equal to m-3, the comparison of the storage string indicated by X is repeated (STEP 157N). X=m
-2, all the signs match, so the storage section 28 is in a normal storage state, and the first storage line number SY or SYH/SYL is also correct information, and the sign comparison control section 14
0 does not change SY, SYH, SYL (STEP 15
7Y).

At X where X≦m-3 (see Figure 2c)
If A≠B, the sign comparison control unit 140
The first memory line number is SY=n, SYH・SYL=n×
(m+1) (STEP 158), and the contents M(X, Y) of the storage section 28 are changed to the contents of the fixed data storage section 144 between X=0 and X=m-3
Make it equal to C _(X) (STEP 159).

FIG. 4A and FIG. 4B are for explaining the details of the operation of the comparing section 20. The operation of the comparison section 20 is similar to the operation of the sign comparison control section 140 described above with reference to FIGS. 3A and 3B. That is, in FIGS. 3A and 4A, the sign comparison control section 140 sends the register 1 to the comparison control section 200.
41 to register 201, comparator 142 to comparator 202, register 143 to register 203,
The fixed data storage unit 144 is connected to the temporary storage unit 34, the transmission path 68a is connected to the transmission path 68c, the transmission path 146 is connected to the transmission path 64a, the transmission path 68b is connected to the transmission path 68d,
Transmission path 148 corresponds to transmission path 64b. Here, the transmission paths 68c and 68d are the transmission paths 6 in FIG.

to X=a-1) and the mode range (X=a)
The difference is that they are the subject of comparison.

The details of the operation of the comparator 20 when searching for a destination name will be explained with reference to FIG. 4B. First, X=
a, Y=SY (STEP 211), and the characters in the mode area of the first storage line are compared (see FIG. 2).
That is, the contents M _{(a, SY)} of the mode area of the storage unit 28 are stored in the register 201 (STEP 212), and the register 20
3 takes in the content T _(a) of the mode area of the temporary storage unit 34 (STEP 213) and compares it (STEP 21).
4). At this time, if the mode area characters are equal (A
=B), proceed to character area comparison (go to STEP 221),
If they are not equal (A≠B), Y is incremented by one (STEP 215), and the process proceeds to comparison of the mode areas of the next memory row (STEP 216). Here, when Y=n (STEP 216Y), it means that all lines have been compared for one character to be compared, and it means that there are no equal characters, so there is an equal character range. Information EQ showing
is set to 0, and the comparison of one character is completed (STEP 217).

If you proceed to the comparison to the character area, set X to X=0
(STEP 221), starting from the comparison of the leftmost characters in the character area. Here, the size of the characters is compared using the code values shown in FIG. 10B. The character area contents M _{(X, Y)} of the storage section 28 are stored in the register 201 (STEP 222), and the contents of the character area of the temporary storage section 34 are stored.
Load T _(x) into register 203 (STEP 22
3). Next, the register 201 is
and the contents A and B of the register 203,
Information about A<B, A=B, or A>B is obtained (STEP 224). The comparison control section 200 is
If <B, add 1 to Y, set X to a (STEP 225), and proceed to comparison of characters in the mode area of the next storage line (STEP 216). If A=B (STEP 224), 1 is added to X without changing Y (STEP 227), and the next memory string is compared (STEP 228).
When X becomes X≧a (STEP 228Y), the comparison of character areas is completed and all characters are equal, so the comparison control unit 40 indicates that there are equal character areas as an output result of the comparison unit 20. Indicating information EQ
is set to 1 (STEP 229) and output together with the storage row address Y. On the other hand, if A > B (STEP 2
24), since the character area of the temporary storage unit 34 is located at an earlier (younger) address than the character area content of the storage line address indicated by Y in the storage unit 28 (for example, the character area in FIG. 10B is smaller than the value of the letter C and is located at a younger address.), the comparison control unit 200 stops the comparison operation at that point, and performs the above-mentioned ET
is set to 0 (STEP 226) and output together with the memory row address 1.

FIG. 5A shows the execution key 109 after the search is completed.
(Fig. 7) shows the output circuit of the dial signal output when the button is pressed, and Fig. 11 is a diagram showing the relationship between the dial key 110 (Fig. 5A), the numeric code, and the dial code. . In FIG. 5A, the dial output unit 30 inputs the telephone number (number area) received from the search control unit 18 from X=a+1 to
40 through light emitting diodes 403a to 403g while sequentially converting the numerical code shown in FIG. 11 into a dial code.
Turn on or off the optically coupled phototransistors 2a to 402g. Here, if the dial code in FIG. 11 is 0, it is turned on, and if it is 1, it is turned off. In addition, 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 Fig. 5B, and when the switch is off, it can make a ring tone, and when the switch is on, it can make a call, and It is also now possible to make dial calls. Dial key 110 is connected to dial transmission circuit 401 through signal lines R1 to R4 and C1 to C3. The dialing circuit 401 is often operated with power (V _a in FIG. 5A) supplied from a telephone office. in this case,
In order to transmit a dial signal from a circuit operating on a power supply other than the central office power supply (FIG. 5a, _Vb ), such as the device according to the invention, the electrical circuit connection has disadvantages such as dielectric strength. Therefore, in the embodiment of the present invention, signals are transmitted using a photocoupler. However, if insulation is not required, the photocoupler may be replaced with a simple transistor. Also, the power supply V _b is connected to the destination number storage device side.
Since it is necessary to be able to make a dial signal even when the key is not supplied, the dial key signal is directly connected to the dial sending circuit 401 in parallel with the output of the photocoupler, as shown in FIG. 5A.
Further, the dial key 110 has a double contact so that it is not electrically connected to the key detection section 12. In addition, the dial prohibition output unit 32 is configured to prevent a dial signal from being output during registration or search.
It is controlled by. 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 as it replaces the dial key 110 of FIG. 5B.

FIG. 5C shows the destination number storage device 4 according to the present invention.
5 is not built into the telephone but is built into an independent dialing device 46, and by switching the telephone line using switching contacts 47a and 47b, it can be used as a device that only makes dialing.

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. 2b. The mode area is divided into a display mode area and a comparison mode area (hereinafter, simply referred to as a mode area will refer to the comparison mode area). 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 value Z 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). In the case of Z=6, an English character is assigned except when the dial key is "4", "8", or "*", so that even if the destination names are the same, they can be distinguished. As a symbol, we are preparing. This is useful, for example, when the same person has multiple phone numbers. Character codes for katakana characters and some symbols are shown in Figure 10B.
Character codes for characters not listed in Diagram B are JIS.
Character codes are given according to the C6220 8-unit code table. If you choose to input characters using this method, you can increase the number of character types without limit by increasing the maximum value of Z to more than 6.
It will be clear from FIG. 10A.

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 First, the registration key 107 (7th
) is pressed, the information is transmitted to the mode activation unit 1 via the key detection unit 12 in FIG.
After performing the recognition operation for confirming the above-mentioned storage state of the diagram, 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=0 to X=m) in the temporary storage unit 34, and then
The letter "T" is written in the comparison mode area and the display mode area (FIG. 6) of the temporary storage unit 34 (hereinafter, this operation will be referred to as registration initialization). Since the letter "T" is only used to identify the mode, other symbols or letters may be used. 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 "T" is replaced with "t" to indicate secret registration. Here, "t" may also be another letter or symbol like "T".

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. Also, the registration control unit 16 sets X=0 after the initial registration settings are completed (see FIG. 6).
Therefore, the cursor will be displayed at the leftmost position. Here, the cursor passes through the X transmission path 64 to the display section 38.
and is always displayed at the position specified by X.

Next, the registration control unit 16 selects the right shift key 10.
3 (FIG. 7) is pressed, 1 is added to X, and when left shift key 102 (FIG. 7) is pressed, 1 is subtracted from X. However, once X=0, no further subtraction is performed. Furthermore, once X=m, no further addition is made (see Figure 6). Further, when the dial key 110 is pressed, if it is the same key as the previously pressed key, the value Z of the same key press count counter (not shown) included in the registration control unit 16 (see FIG. 10A). (see hereafter simply referred to as Z) is increased by one. However, when Z=7, Z=1. Further, Z is set to 1 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 registered by the dial key value and the Z value.
4, and the character conversion unit 24 converts the characters according to the character table shown in FIG. 10A into the first character table.
The registration control unit 1 converts it into the character code shown in Figure 0B.
Return to 6. Since the registration control unit 16 writes the received character code to the X position of the temporary storage unit 34,
The character is updated each time dial key 110 is pressed unless shift keys 102 and 103 are pressed and X changes, but if X changes, the most recently written character remains.

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 and X=a, the registration control unit 16 changes X to x=a.
and instructs the display selection unit 36 to change the display area to a numeric area. Changes in the display contents on the display 101 during this period are shown from T11 to T13 in FIG. 8. When the left shift key 102 is pressed and X=a changes from X=a+1, the registration control section 16 instructs the display selection section 36 to change X to X=a-1 and set the display area to the character area. The above-mentioned character input becomes possible again. Next, the registration control section 16
After X=a+1, the input dial
Regarding the key 110, in order to convert it into the numeric code shown in FIG. 11, the dial key information is passed to the numeric conversion section 26 (FIG. 1), and the numeric conversion section 26 returns the corresponding numeric code to the registration control section 16. , writes the numerical code in the position indicated by X in the temporary storage section 34, and then increases X by one regardless of whether the shift key 102 or 103 is pressed. 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 controls the comparison unit 2
0 to compare the contents of the character area and the mode area of the temporary storage section 34 with the contents of the character area and mode area of all the storage lines in the storage section 28 (FIGS. 4A and 4B). The comparison unit 20 compares the two as described above, and if the character area and mode area are equal as a result, sets EQ=1 (STEP 229),
If they are not equal, set EQ=0 (STEP 217,
226), is output together with the value Y of the storage row. The registration control unit 16 passes the output to the organizing unit 23. If EQ=1, the organizing unit 23 makes the content M _{(X, Y)} of the memory line indicated by Y equal to the content T _(X) of the temporary storage unit 34, and then notifies the registration control unit 16 that the process is completed. , and if EQ=0, the memory rows from SY to Y-1 shown in FIG. 2c are made younger one by one to provide a memory space. That is, M _(x,sy-1) ←M _(x,sy) M _(x,sy) ←M _(x,sy+1) : : : M _(x,y-2) ←M _(x,y- Move the contents of the storage section 28 as in ₁₎ (assuming that X changes from 0 to m), then move the contents T _(x) of the temporary storage section 34 to M _(x,y-1) , From M _(x,y)
Leave M _(x,o-1) as before, then subtract 1 from the value of SY in Figure 2 c to create a new SY, subtract m+1 from SYH・SYL to create a new SYH・SYL, and then,
Notify 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, if the character code is defined according to the 8-unit code table of JIS C 6220, the contents of the storage section 28 will be
They will be sorted in ABC order.

Search operation There are two types of search operations: a normal search, that is, a search for only destination information registered without pressing the secret key 106 (Fig. 7) at the time of registration (those whose mode area is set to "T"); , and a secret search, that is, a case where the private key 106 is pressed at the time of registration and then the registered destination information (the mode area is "t") is searched. These two cases will be described below, but as a specific example, it is assumed that the information has 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 uses the SY in FIG. 2c.
The content M _{(x, sy)} of the memory line indicated by is transferred from the memory section 28 to the temporary memory section 34, that is, T _(x) , and the display is changed to the 9th B.
Do as shown in K1 in the figure. At this time, the display mode area is changed to "K" to distinguish it from the time of registration (FIG. 8), and the cursor is not displayed. Also, the mode range is assumed to be "T". The destination information displayed immediately after pressing the search key 108, as in this case,
It may be other information than the information of the storage line indicated by SY.

Next, when one of the dial keys 110, for example "2" is pressed, the search control section 18 passes the key information and Z (FIG. 10A) to the character conversion section 24, in exactly the same way as the registration operation described above. , character conversion section 2
4 receives the code for the character "ka" and writes it to the position of X=0 in the temporary storage section 34 via the transmission path 64. Characters in positions from X=1 to X=a-1 are not to be compared, so blanks are written. Therefore, the display 101 displays as shown in FIG. 9B K2.

Next, the search control unit 18 instructs the comparison unit 20 to perform a comparison. The comparison unit 20 stores the contents of the character area and mode area between the first storage row address SY (SY=n-10 in the case of FIG. 9A) to the last storage row address Y=n-1 in the temporary storage section 34. The comparison is repeated until it matches or becomes larger than that of , and as a result, EQ and Y are output. In the case of the specific example explained in FIG. 9B, the value of the code shown in FIG. 10B is larger for "ka" than the first character "i" of "Ishikawa", and when compared with "kaka" in FIG. Since the first characters are equal, the second character is compared, and since the second character in the temporary storage unit 34 is a blank, comparing this blank with the second character of "Kaka", it becomes "Kaka".
Since the value of the second character code is larger, “ka”
is determined to be smaller than "kaka", and the comparison unit 20
outputs EQ=0, Y=n-9. Next, the search control section 18 stores the contents of Y=n-9 in the temporary storage section 3.
4 and designates the display area as the character area, so the display area 61 is displayed as K3 in FIG. 9B. Similarly, when the dial key "5" is entered, the first character "na" to be searched for is displayed as K4 in FIG. 9B (FIG. 10A), followed by "NA".
"Name" (Y=n-3 in FIG. 9A), which has a larger code value and is the content of the closest character area, is displayed as K5 in FIG. 9B. When the up scroll key 104 is pressed, the search control unit 1
8 subtracts 1 from the value of Y at that time. For example, in the specific example, the value of Y at that time is Y=n-3, so we newly set Y=(n-3)-1=n-4 as n-
The contents of the fourth storage line are transferred to the temporary storage section 34. At that time, the display on the display 101 will be as indicated by K6 in FIG. 9B. Similarly, if the up scroll key 104 is pressed again, the screen will become like K7 in FIG. 9B.

The search control unit M18 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. Search control unit 18
In this case, the mode area indicating whether the destination information read from the storage unit 28 is a normal search or a secret search is set to the search control unit 1.
8, Y is not updated. 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), no more Do not increase or decrease the value of Y. Therefore, when the mode range changes from "T" to "t" in FIG. 9A, the value of Y will not be increased any further, and the secretly registered portion will not become the search output (mode Area characters are also JIS C
Since they are ranked and registered according to the 8-unit code table of 6220, a group whose mode line is "T" and a group whose mode line is "t" are formed separately at the time of registration). If secret registration is not done, scroll key 1
The range in which the value of Y can be increased or decreased by 04 or 105 is from Y=SY (in the case of Figure 9A, SY=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 dial key "2" will display K8 of FIG. 9B as described above. Next, when dial key “2” is pressed again, the first
Since Z in diagram 0A is Z = 2, "K" is placed at X = 0 in the temporary storage section 34 and the comparison is started.
Since there is no character region starting with "K" in FIG. 9A, the character region starting with "K" with a larger code value than "K" (Y=n-6) is the output of the comparison unit 20, and the It will be displayed like K9 in Figure 9B. If dial key “2” is pressed further,
In Figure 10A, Z is 3 and "ku" is the temporary storage section 3.
The “ku” is placed at X=0 in 4 and the comparison starts.
The character area starting with is already displayed, so the 9th
The display does not change like K10 in Figure B. When dial key “2” is further pressed, Z in Figure 10A
becomes 4, "ke" is placed at X=0 in the temporary storage section 34, and the comparison is started with Y=n-5 (Figure 9A).
The destination information of is searched and the result is K11 in Figure 9B.
It will be displayed like this.

When the execution key 109 is pressed after searching for a desired destination name using the operation method described above, the search control section 18 passes only the numeric area of the temporary storage section 34 to the dial output section 30. Thereafter, as described above, the dial code shown in FIG. 11 is output from the dial output section 30, and when the dialing is completed, the search control section 18 is notified of this, so the search control section 18 performs the dial code shown in FIG. 9B as shown in K12. After displaying a 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, K1 in FIG. 9C is displayed in the same manner as in the normal search. Next, when the secret key 106 (FIG. 7) is pressed, the search control unit 18 knows that the search is a secret search, and changes the display as shown at K2 in FIG. 9C. That is,
After setting all the contents of the temporary storage unit 34 to blank characters, write the character "K" indicating a secret search in the display mode line and "t" in the comparison mode area, and then wait for input. . The input method is exactly the same as that described for the registration operation, and is performed using the dial key 110 and shift keys 102 and 103. K3 to K15 in FIG. 9C describe the case where "Kensaku" is input in the character area (destination name).

When the input is completed in this way, the secret key 1 is used to notify the search control unit 18 that the input has been completed.
When 06 is pressed again, the search control unit 18 instructs the comparison unit 20 to compare the contents of the character area of the temporary storage unit 7 with the contents of the character area and mode area of the storage unit 28, and the comparison unit 20 obtained as a result The output EQ of is checked, and if EQ=1, the contents of the address indicated by the output Y of the comparison section 20 are transferred to the temporary storage section 34. That is, the display 61 displays something like K16 in FIG. 9C. If EQ=0, there is no corresponding item, so a warning is generated, but the contents of the temporary storage section 34 are not changed. The operation of the search 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 a secret search, if the characters in all the character areas do not match, the search output will not be output, so encryption is easy. In other words, the number of combinations of katakana characters is
Assuming 50 words, there are 50 to the power of (a-1), which is nearly impossible to search unless you have memorized them. Even if the name of a secretly registered destination 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. It is superior to the conventional method of using numbers as symbols.

[Second Embodiment] The first embodiment of the present invention has been described above, but
Further, as a second embodiment, a key input section 1 and a display section 3
12, a case in which the device 8 is installed in a remote location will be explained with reference to FIG. 1.

FIG. 12 shows only the portions of FIG. 1 that have been changed to realize the second embodiment.
However, the key input section 10, display section 38, display selection section 36, and temporary storage section 34 are the same as those shown in FIG. The input key information transmitted from the key input section 10 through the transmission path 61 is transmitted to the mode activation section 14 of the destination number storage device as input key information through a transmission means consisting of a transmission section 81, a transmission line 82, and a reception section 83. communicated. The subsequent operation of the telephone number storage device is the same as that in the first embodiment. On the other hand, the content written in the temporary storage unit 34 is passed through the display selection unit 36, and the value of X indicating the cursor position (character input position) is transferred to the transmission path 64.
The signal is supplied to the transmitting section 88 through the transmitting section 88 , the transmission line 87 , and the receiving section 86 , and is transmitted to the display section 38 through a transmitting means composed of the transmitting section 88 , the transmission line 87 , and the receiving section 86 . 72a is a transmission path for transmitting character or numerical information, and 64c is a transmission path for transmitting the value of X.

As a specific example, this second embodiment may be applied to a key telephone device, etc., but in a key telephone device, the dial generating section is generally placed in the main device that performs overall control. A destination number storage device according to the 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 transmitter, a transmission path, and a receiver, and the destination number storage device according to the present invention is required in the input key information. Control key information is added, and in addition to the information specific to the button telephone device, the input information to the storage section described above is added and transmitted to the display information, and the control section that is originally built in the button telephone device is used as an intermediary. You can receive information under . When making a dial call, the dial prohibition output and dial code are passed from the destination number storage device to the control section built in the button telephone device, thereby making the dial call. In this case, the dial code need not be the dial code shown in FIG. 11, but may be of other information format, such as a decimal 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, a plurality of the transmission means shown in FIG. 12 are provided by a time-division method or a space-division method, and a plurality of display portions or key input portions are also provided. In this case, individual terminal phones tend to be used exclusively for personal use, so
The destination information to be registered is also different for each individual, 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. However, fixing the storage area is not efficient when there is variation in the amount of individual registrations, so it is desirable that the storage area is variable according to the amount of registrations.

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. Similarly, identification characters for secret search or mode display (for example, " If you enter a character other than "T", "t", ), a group will be created with the input character as an index, and within the group,
Destination names can be arranged in alphabetical order. In button telephone devices, each terminal telephone is also numbered, so determine a character corresponding to that number and write that character in the mode area when the terminal telephone is used for registration or search. Just do it. There is no particular change in the search operation when the scroll key is pressed, and the search control unit 18
If the contents of the mode area temporary storage section included in the terminal phone are rewritten to the above-mentioned characters corresponding to the terminal telephone, there will be no interference with other groups. The characters in the mode area for display are as described above (“T”, “t”, “K”, “k”), and the mode area characters stored at the time of registration are those unique to the terminal phone. shall be taken as a thing. However, in the case of secret registration or secret search, the mode area character is "t" for any 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 50 syllables can be changed. Since they are displayed sequentially, you can easily select characters without having to think about the operation, and there is no limit to the number of characters in each line of 50 syllabaries, and lowercase katakana characters can also be provided, so you can express the destination name freely. In addition, since alphabetical 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 destination information that you want to keep private without any restrictions, and by registering it in major categories, one of the major categories can be used as a personal phone number list. This allows flexibility in how it can be used. When searching, you can search for the destination name by simply pressing the same dial key that corresponds to each row of the Japanese alphabet once or multiple times, and you can use the scroll keys to search the entire range, so you can change the type of key you are using. There is less need for it. After searching, you can simply press the execution key to make a dial call, so there is no risk of making an erroneous call. 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. That is, when destination information is composed of a destination name and a telephone number as in the present invention,
Since the destination name is the object of the search and the telephone number is incidental, there is no need to display it, so 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. The present invention can be applied to any device having a dialing function, such as a facsimile machine that communicates using a telephone line, in addition to the above-mentioned telephone, dial (dedicated) device, and button telephone device.
