Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic memo device that searches for information using an index.

A conventional electronic memo that stores a large number of storage units consisting of one piece of information and one index, and automatically searches and outputs the information corresponding to the specified index by specifying any index among them. The device is often used as a telephone memo in which, for example, a name is stored as an index and a telephone number is stored as information, and when a name is designated, the corresponding telephone number is read out.

However, since each person generally has an occupation along with their name, there may be cases where it is desired to read out the same phone number for both the name and occupation.In such cases, the above device has only one index. Because there was only one available, it was only possible to search for a phone number using either name or occupation.

Also, in order to be able to use the phone memo even when a single phone number is shared by many people, such as a main phone number, it is possible to read the same phone number no matter which name of multiple people is specified. However, in the conventional device described above, it is extremely inefficient in terms of memory usage, as it has to allocate a number of indexes corresponding to multiple names, and the corresponding information must all be the same phone number. I had to make it a method.

The shortcomings of the conventional electronic memo device as described above are caused by the fact that only one index corresponding to the information to be searched is assigned. Therefore, an object of the present invention is to provide an easy-to-use electronic memo device that has a plurality of indexes corresponding to one piece of information.

To summarize the present invention, a plurality of indexes can be set for one piece of information, and a control circuit is provided that automatically searches for information common to the designated index no matter which one of these indexes is designated. The content is an electronic memo device, and it is also possible to automatically search other indexes related to the specified index.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of the circuit configuration of an electronic memo device according to an embodiment of the present invention. In the figure, NAM is an index memory that stores indexes such as people's names and occupation names;
NUM is a numerical memory that stores information such as telephone numbers (numeric data, etc.), and these two memories store indexes and their corresponding information.

Note that these two memories may be configured with one memory, for example, a random access memory (RAM) in terms of implementation.Next, the DSP is a display device consisting of a dot type display device,
SC is a display control circuit that controls the driving of this display device DSP.

Further, this display control device is configured to output the stored contents of the output buffer memory NAB2 of the index memory NAM and the output buffer memory NUB of the numerical memory NUM to the display device DSP in response to a coincidence output from a coincidence determination circuit J, which will be described later. Ru. In this case, the display control circuit DS performs certain functions so that the display on the display device DSP is a running display.
It may be added to C. K is an alphanumeric key, KK is a search start key that instructs to start searching for information, NA is an index manual key, and NU is a numerical data input key that becomes information, and these keys are on the same key panel. Arranged.

EC is an encoder that converts the input contents of key K into code,
KB is a key input buffer for transmitting the contents of the encoder EC to the next stage, and J is a coincidence determination circuit that compares the contents of this key input buffer KB with the contents of the output buffer memory NABl of the index memory and determines whether they match. If they match, the above-mentioned display control device and index memory NAM
address counter and will be described later? Code detection circuit QS
Emit an output.

AR, is a register connected after the address counter ACl and stores the currently specified memory address of the index memory NAM.Similarly, AR2 is connected after the address counter AC2, and is a register that stores the currently specified memory address of the index memory NAM.
This is a register that stores the currently designated memory address.

IC, IC2 are input control circuits for index memory NAM and numerical memory NUM, respectively, and input data to index memory NAM and numerical memory NUM in response to input from index input key NA and numerical data input key NU. Regulation? , or create some code to indicate data divisions, as described below.

ASl and AS2 are the input control circuits C1 and IC2 mentioned above.
is connected to the index memory NAMl and the numerical memory N
This is an address stack register that stores the address next to the last memory address already stored in each UM, and is used when inputting data.

As mentioned earlier, NAB1 and NAB2 are the output buffer memories of the index memory NAM, but the former has a capacity to store only one index, and the latter has a capacity to store all indexes corresponding to one numerical data. have.

Moreover, these contents are updated in accordance with the detection of heat-setting codes that separate the indexes. This will be discussed later. QS is one of the above specific codes? Detect code? In the code detection circuit, here? Until the code is detected from the output of the index memory NAM, the count up signal of the τ address counter ACl is output, and ? By detecting a code, it functions to transfer certain data stored following the code to the address register AR2.

Note that this certain data is the storage address in the numerical memory NUM of the numerical data corresponding to the specified index, which will become clear from the following explanation. VC is an audio output control unit, and SP is a circuit that synthesizes the contents of the output buffer NUB into audio using a speaker and outputs the result as audio.
Examples of gutter stored in the index memory NAM and numerical memory NUM in the electronic memo device having the above configuration are shown in FIGS. 1 and 2.

FIG. 1 shows a part of the data stored in the index memory NAM converted into characters and expressed in the order of addresses. In the same figure, $ code, / code, ? The code is a specific code, and the $ code is located at the first address of a group of indexes that are related to each other. The code is located at its final address and/the code delimits the indexes within a group of indexes. Therefore, in the case shown in the same figure, "L layer dipping" and "NAKAMURA All
and "S.KIKAKU" form a group of indexes.

or,? The numerical code between the code and the $ code located at the first address of the next index group indicates the first address in the numerical memory NUM where numerical information is stored corresponding to the index group at the immediately previous address. show.

Therefore, "TANAKA],"NAKAMUR.Al,"
S. It can be seen that the numerical information corresponding to each index of KIKAK[Jl is stored from address 801A in the numerical memory. Then, next is the numerical memory N.
If the characterized numerical data stored in the UM is shown in FIG. 2, it can be seen that "395" is stored in order from address 801A.

The / code, which is a specific code of the next address, is a code that separates numerical information. Therefore, from the structure of the above memory contents, [TANN Yulayer, "NAKAMURAI, [S.K.
The numerical information “395” is associated with each index of “IKAKU”, and “FUKUI”
The index of ``0775621382'' has numerical information, and the index of ``PAT-G'' has ``4''.
19'' numerical information are associated with each other. Note that the numerical information in this example is a telephone number. Next, the detailed operation of searching for indexes and numerical information that are in a corresponding relationship as described above will be explained below with reference to FIG. Now let's say you want to know Mr. Tanaka's phone number.

In this case, first press key K to select "T", "A", [N], "A", "
Enter "K" and "A" in order, and then press the search start key KK. As a result, the match determination circuit J is connected to the key input cover KB.
“TANAKA” encoded in
Compare with one index stored in . If there is a mismatch, the match determining circuit J outputs a mismatch signal to the address counter AC, and updates the specified address in the index memory NAM. As mentioned above, the contents of the output buffer memory NAB are updated at regular intervals;
The update is performed by detecting the $ code or / code. Also, is the other output buffer memory NAB2 a $ code? While detecting the code, the index group between them is stored, and the contents are updated every time a $ code is detected. Now, the contents of the output buffer memory NAB, [TA
NAKA”, then what is the match judgment circuit J? Outputs a signal to the code detection circuit QS and display control circuit DSC.

? Is code detection circuit QS from index memory NAM? A count up signal is sent to the address counter AC until the code is output, and the specified address in the index memory NAM is counted up. ? If the code is detected, the next data is the address data of the numerical memory NUM as described above, so this data "801A
" is transferred to address register AR2.

Therefore, the contents of the numerical memory NUM addressed by the address register AR2 are output and stored in the output buffer memory 1JNUB. Output buffer memory MB
A count-up signal is sent to the address counter AC2 until the / code is detected, and the address of the numerical memory NUM is incremented. Therefore, the output buffer memory NU
"395" will be stored in B. Also, at this time, since the address counter ACl has finished counting up, the output buffer memory NAB2 contains "TANAK".
ANAKAMURAS. K[KAlCU! is memorized.

At the same time, the display control circuit DSC receives the coincidence output from the coincidence determination circuit J, and is in a state of supplying the storage contents of the output buffer memories NUB and NAB2 to the display device DSP. FIG. 3 schematically shows the state displayed on this display device DSP. From this displayed content, it can be seen that Mr. Tanaka's phone number is 395. Furthermore, it is also revealed that Mr. Nakamura's phone number is 395, and furthermore, it is also revealed that the phone number where the planning section is located is 395. In addition, since an audio output device is provided in addition to the display device as an output device, the contents stored in the output buffer memory NUB, that is, "395" can be audibly heard through the audio output control section C and the speaker SP.

In addition, when searching for Mr. Nakamura's telephone number or knowing the telephone number of the planning section, the same display contents and audio output can be obtained by the same operation.

Also, in Mr. Fukui's case, his home phone number is 0775.
-62-1382 can be searched in the same way.
The above is a specific example of a search. Next, a case will be described in which an index and a numerical memory are respectively input and stored in the memory NAM (5NUM) shown in FIG.

For example, to explain the case where you want to store "FUKUI" as an index, first, "F", "U", "K"
Input "U" and "I" using key K, then press index input key NA.

As described above, the human power control circuit 1C1 is activated by pressing the index input key NA, and the operation details are as follows.
First, the contents of the address stack register AS1, which stores the address next to the last address already stored in the index memory NAM, are stored in the address register AR1.
Then, a $ code is created and output to the index memory NAM. Subsequently, "FUKUI" encoded and stored in the key entry buffer KB is transferred to the index memory MM. Furthermore, the starting address of the numerical memory NUM where the telephone number (numeric data) corresponding to that index is to be stored, and ? The code is transferred to the corresponding index memory. Note that the first address of the former is obtained from the address stack register AS2 which stores the address next to the last address already stored in the numerical memory NUM, and the first address of the latter? The input control circuit 1C creates the code itself. In this way, index memory NAM
``$FUKUI?Table 8'' is stored in . In addition, “h
", [g" each constitutes one word length with two words, and also "Chapter"
is stored in the address before "B", but the actual specified address is "801E".Next, "
The operation when storing numerical data corresponding to "FUKU", that is, Mr. Fukui's telephone number, will be explained.

In this case, first, the numerical data that is the telephone number, ie, 0
775621382 in order from the key K, and then press the numerical data key NU.

5 As mentioned above, the human control circuit 1C2 is activated by pressing the numerical data manual key NU, but the operation content is first the address of the numerical memory NUM stored in the address stack register AS2, that is, [801E in this case]. is transferred to address register AR2.

Next, "0775" stored in the key-in cover KB is
621382" to the numerical memory NUM, and finally /
Create and output code. Therefore, the numerical memory NUM
From the address "801E" 4, "0775621
382/'' are stored in order.

In the above example, there is a single index [FUKUI], but if there are multiple indexes, the input control circuit 1C1 automatically creates a /code from the second index input and stores the index in the index memory NAM. Output to.

Therefore, "TANAKA],"NAKAMURA1,"
S. KIKAKU] is a group of mutually related indexes, and the corresponding numerical data is [395]. The input operation procedure for storing this is "T" and "A".
“N” “A” “K” “A], “N” “A” [K” “A]
"M""U""R""A], [NA], "S""."
K"[I" [K] [A"[K" [U] [N] [A], [
3'', ``9'', ``5'', and ``NU'', and the stored content pattern is as shown in FIGS. 1 and 2.

As shown in Figure 2, the index memory stores the $ code and ? A group of indexes is placed between the codes, and each index is divided by /code, so it can be easily distinguished from other indexes, and the memory area used can be kept to a minimum.

As described above in detail in the embodiments, according to the present invention, a plurality of indexes can be stored in association with one piece of information such as numerical data, so it is possible to specify which index among the plurality of indexes. The same information can be searched and output even if the same information is searched.

In addition, unlike conventional devices, one index does not correspond to one piece of information, but the same information can be associated with a number of indexes as a set, so the same information can be assigned to each index. It is not necessary to store them separately in correspondence with each other, but it is sufficient to store them in a single format. Therefore, the memory usage area can be kept to a minimum, resulting in extremely high efficiency. Note that when a name is stored as an index, the corresponding information may include, in addition to the above-mentioned telephone number, the name of the company where the person works and the name of their affiliation.
