Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device having a dictionary-like function that facilitates searching.

When trying to read out, for example, "EXCHANGE" from what can be called an "electronic dictionary" in which information about words is stored in a storage device in alphabetical order, for example, at least 8
Each key must be pressed correctly. However, if you make a mistake and cannot read the data,
If you don't know the exact spelling but want to check the word you have a rough idea of, or if you want to look up the spelling in alphabetical order like in a regular dictionary,
It is desirable to have a function that can semi-automatically sequentially detect words with subsequent spellings after inputting a certain number of correct spellings. Electronic devices equipped with such functions have already been developed in the past. However, for example, if you just enter “EX”, many words starting with “EX” will appear, including “EXCEED”, “EXCEL”, and “EXCEPT”.
etc., it takes a long time for the desired “EXCHANGE” to appear, and “EXCHANGE”
was the desired word, “EXCITE” was the desired word, or whether the searcher was looking for a word that ends with “EX” or a word that ends with “EXC”. There are cases where it is not clear even to the person in question. The reason why a relatively expensive "electronic dictionary" is intentionally used instead of a regular dictionary is for purposes such as learning and memorization purposes and for ease of searching, so the person in question searches for "EX". Noka “EXC”
It would be desirable to be able to always clearly recognize the distinction, such as whether the user is searching by

SUMMARY OF THE INVENTION An object of the present invention is to improve the above-mentioned problems and provide an electronic device suitable as an electronic dictionary.

In order to achieve this purpose, in the present invention,
If you entered only “EX” at the beginning of the search, it would be “EX-CESS”, “EX-CHANGE”, etc., and if you entered “EXC”, it would be “EXC-ESS”, “EX-CHANGE”, etc.
For example, "EXC-HANGE", the characters input by key at the beginning of the search and the subsequent spelling are clearly separated and displayed using a predetermined symbol such as a hyphen.

The present invention will be described in more detail below with reference to embodiments shown in the accompanying drawings.

In the drawing, KB is a keyboard, and on this keyboard KB are alphabet keys AK,
Place search key SK etc. OR gate the key output of each key □A to □Z of the alpha alphabet key group AK
Pass it through OR1 and connect its output terminal to signal line LX. In addition, each key □A of the alpha alphabet key group AK
～□Each key output of Z is alpha abet encoder
Supply to AEC. This encoder AEC generates a binary code corresponding to the alpha-abbreviation.
The output of search key SK is led to signal line LZ. Therefore,
When you operate the alphanumeric keys □A to □Z, the logical 1 signal line will change as many times as the number of alphanumeric characters pressed.
The binary alpha abet codes corresponding to the pressed alpha abet keys □A to □Z are connected to the signal line LY on LX.
, the press of the search key SK is output to the signal line LZ.

ICR is an input character number register that matches the maximum number of characters in a display or word and counts the number of alpha characters input from the signal line LX. IDR
is 2 of the alpha bet input from the signal line LY.
This is an input data register that stores the evolution code. The ROM is a fixed storage device that stores a plurality of words corresponding to the contents of a dictionary, and is composed of an address decoder section AD and a data section DAT. AC is the address decoder section in ROM
This is an address counter that specifies and selects a certain address in AD, and forms a loop with an adder circuit ADD that adds 1 to the address number, and the address number increases by 1 each time this loop is circulated. When the search key SK is pressed, the key output is sent from the signal line LZ to the reset terminal R of the adder circuit ADD.
, this loop starts working and
The address decoder section AD is controlled by AC output, and the contents of the data section DAT are read out at regular intervals.
These contents are sequentially temporarily stored in the output data register DATR. The sequential data reading operation by this loop circulation is performed by the coincidence detection circuit CON, which will be described later.
When a match is detected, the stop signal STS is sent to the adder circuit.
This continues until input to the addition stop input terminal ST of ADD. Data section DAT in fixed storage device ROM
Word data is stored in the same code form as the alpha-abbet binary code created by the encoder AEC in response to the key pressed when the alpha-abbet key group AK is pressed. AND gates G1 and G2 pass through the contents of the input data register IDR and the contents of the output data register DATR, which are output in series, for the number of input alphanumeric characters and transfer them to the coincidence detection circuit CON, so that both contents are the same. Determine whether or not. Note that the contents of the input data register IDR that have passed through the AND gate G1 are also stored in the display register DR via the OR gate OR2. The display control circuit is
Input character count register ICR and input data register
It is composed of gates G1, G3, OR2, an inverter INV, and a delay circuit DEL that delays the signal from the output data register DATR than the signal from the input data register IDR.

DSP is the above-mentioned display control circuit and display register.
This is a display device for displaying word information output via DR.

Now, for example, when keys □E to □X in the alpha alphabet key group AK are pressed, the binary code of "E" and "X" is stored in the register IDR, and 1 is stored twice in the register ICR. Ru. After that, when the search key SK is pressed, a loop consisting of the adder circuit ADD and the address counter AC starts, and the contents of the data section DAT are first read out from the first "A" section via the address decoder section AD, and output. Two characters in the above content are supplied to the coincidence detection circuit CON via the data register DATR and the AND gate G2.

On the other hand, the binary code corresponding to EX in the input data register IDR is supplied to the coincidence detection circuit CON via the AND gate G1. Here, AND gates G1 and G2 only allow the code for two characters to pass according to the output of the input character count register ICR, and are closed after that period, but AND gate G3
is closed by inverter INV for the above-mentioned period to prevent DATR output, and is then opened.

In the coincidence detection circuit CON, the "EX" code from the AND gate G1 is compared with, for example, "AB" sent from the register DATR through the AND gate G2, but at this time a match cannot be found, so the coincidence detection signal is sent out. Not done. Match detection circuit
CON can be composed of, for example, an exclusive OR circuit or a flip-flop, and TX is a synchronization signal that controls this circuit CON, and is also synchronized with the +1 timing of the ADD circuit. After a certain period of time sufficient to compare the contents from the AND gates G1 and G2 supplied to the coincidence detection circuit CON, if the contents do not match as described above, the addition circuit ADD increases the output by 1. The contents of the address are output from the DAT section to the output register DATR via the address counter AC and the AD section of the fixed storage device ROM, and through the same processing process as described above, the first two characters of the code are output to the match detection circuit. CON, where it is compared with the “EX” code from register IDR. The sufficient time for content comparison in the compare and match circuit CON is actually extremely short since all operations are performed electronically, and such comparison work is performed by reading out, for example, "EXACT" from the data section DAT. The process is repeated without stopping until . During this time, even if the time required for the comparison operation is, for example, 50 μs, the actual total time is extremely short.

“EXACT” is read from the data section DAT,
When the match detection circuit CON detects a match between the first two characters "EX" code and the key-input code "EX" in the register IDR, the match detection circuit CON sends a stop signal STS. It is sent and stops the adder circuit ADD. Meanwhile, "ACT" (which is the "tail" of the word) that follows "EX" (which is the "head" of the word) in "EXACT" (which is the "word") is the AND gate G.
3, is delayed by a time corresponding to one character in the delay circuit DEL, and then is stored in the display register DR via the OR gate OR2. The contents of this display register DR are converted to normal characters and "EX" is blanked on the display DSP (corresponding to the delay time due to DEL).
“EX〓ACT” is displayed in response to “ACT”. After this, when you press the search key SK, the ADD circuit operates and reads out the next address, for example "EXAGGERATE", but the first 2
The match detection circuit CON sends a stop signal STS because of the character “EX”, and the loop consisting of ADD and AC stops again after just reading one word “EXAGGERATE”, and the display DSP shows “EX〓
AGGERATE” will be displayed. From now on, use the search key
For example, “EX〓CEL” every time you press SK repeatedly.
After “EX〓CEPT” etc. is displayed, “EX〓
CHANGE" will be displayed. During this time, you can learn about words starting with "EX" or check your own vocabulary. Here, if you remember that the next letter of "EX" is "C", If you rekey “EXC”, “EXC〓HANGE” will appear.
is searched faster than when the key input is “EX”, and if you press the search key SK again after that, “EXC” is searched.
〓ITE” is displayed.

As described above, according to the present invention, of the searched and displayed words, the portion input for search can be displayed separately from other portions.

Further, according to the present invention, it is possible to search for a target word relatively easily, and it is also effective for learning similar words and learning to look up a dictionary in alphabetical order.

Note that in the above example, a blank was inserted into the word displayed by the delay circuit DEL to distinguish the input part, but the present invention is not limited to this example. Of course, it may be configured as follows. Furthermore, the present invention can be effectively used to search for words in various languages, such as words written in alphabetical order instead of words written in alphabetical order.
