Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device, and in particular, it has a function of storing character information input as registration information in order of a predetermined character and storing the information, and searching and outputting the registration information according to the input. It relates to electronic devices.

[0002]

2. Description of the Related Art In recent years, a small electronic device having a function such as a telephone directory function for storing a large number of character information such as a telephone number, a name, etc., and searching and displaying it has been popular in the market. In such electronic devices, the ease of search is important, and the character information input as what should be registered should be entered in Iueo order or A
Automatically rearrange and store in alphabetical order such as BC order, and search for this one by one in the order of character according to the input of the search key (hereinafter referred to as "order search"), or the characters entered for the search. Or character string (hereinafter referred to as "label character")
It is possible to search for character information in which the first character or character string matches (hereinafter referred to as "label search").

[0003]

When the label search is performed in the above conventional example, when the corresponding registration information can be searched, it is displayed, and thereafter, the registration information subsequent to the corresponding information can be called and displayed in order. Is becoming

However, if there is no corresponding registration information in the label search, a message such as "arimasen" is issued and the label search is terminated and the initial state is returned. For example, if the user wants to sequentially look at the names of people beginning with the line "ta", enter "ta" as the label character and press the search key to search, the name of the person starting with "ta" will be registered. If there is no name starting with "ta" but only names starting with "chi" or "tsu" are registered, the message will return to the initial state after the message "Arimasen" is displayed.

For this reason, in order for the user to see a name starting with a character under "chi" on the line "ta", the user must enter "chi" or less as the search character again or perform a sequential search from the beginning "a". I have to. In the case of the former method, it is particularly troublesome when the rotary method is adopted as the input method of the keyboard for inputting characters. With the rotary method, in order to reduce the number of character keys, for example, "a", "ka",
The character keys of 5 characters in each line of "sa", "ta", "na" ... are common, and if the key of the "a" line is pressed once, "a",
This is a method of inputting a different character depending on the number of times of pressing, such as "a" by pressing twice. In this method, if "H" is used, the input operation of "H" is troublesome.

As described above, in the above-mentioned conventional example, there is a problem that the search operation is time-consuming and time-consuming, and the battery of the power source is wasted.

[0007] Therefore, an object of the present invention is to provide a structure in which an electronic device of this kind can efficiently perform a search by a simple operation.

[0008]

In order to solve the above-mentioned problems, according to the electronic apparatus of the present invention, the input means for inputting information and the character information input as registration information by the input means are converted into predetermined characters. Storage means for storing the data in order.
An output means for outputting information, in accordance with an input by the input means, a sequential search in which the registered information in the storage means is sequentially searched in a character order and output by the output means, and a label character or character input for the search An electronic device for performing a label search for searching and outputting registration information having a column at the beginning, and when there is no corresponding information by performing a label search according to the input by the input means, and subsequently performing the order search,
A configuration is provided in which a processing unit is provided for performing an order search from the character information next to the label character or the character string in the character order in the registered information of the storage unit.

[0009]

According to this structure, even when the label search is performed and there is no corresponding information, it is possible to perform the order search from the character information next to the label character or the character string in the registered information in the character order. ..

[0010]

Embodiments of the present invention will be described below with reference to the drawings. Here, a small electronic device having a telephone directory function for storing and retrieving name and telephone number information is exemplified. In the following description, for the sake of convenience of description, it is assumed that the label search is performed by using one label character instead of a character string, and the search is performed by matching or not matching the initial letter of the registered data.

FIG. 1 shows the top surface of the electronic device of the embodiment. The electronic device 30 is formed into a credit card size, and the display 1 and the keyboard 2 are provided on the upper surface.

The display 1 comprises a liquid crystal display or the like, and has a kana / alphabet data display portion 1a for displaying kana and alphabetic characters and a numeric data display portion 1b for displaying numbers such as telephone numbers.

Further, the keyboard 2 has a character key group at a portion 23, so that a kana can be inputted by the rotary system described above, and also alphabetic characters and numbers can be inputted. For example, with the character key of reference numeral 25, the kana of A line and A, B
And 7 can be input, and the kana of the row and I, J and 4 can be input with the character key of reference numeral 26. The input mode of Kana, English letters, and numbers can be changed by the Kana / English / Numeric key 22 provided separately.

After inputting the data of the name or telephone number by the character key group 23 and pressing the registration key 24, the data is stored and registered in the data memory 4 described later. The registration data is saved as a backup even when the electronic device is powered off.

Reference numeral 21 is a pair of search keys. By simply pressing one of the search keys 21, registered data can be searched in ascending or descending order in the character order (aiueo). Further, if the search key 21 is pressed after inputting a desired character with the character keys, the label can be searched with the input character as the label character.

Reference numerals 27 and 28 are an ON key and an OFF key, respectively, for turning the power of the present electronic device on and off. Reference numeral 29 is a cursor movement key for moving a cursor (not shown) between the display units 1a and 1b of the display device 1.

Next, the circuit configuration of the electronic device will be described with reference to the block diagram of FIG. In FIG. 2, reference numeral 5A is a ROM
It is a program memory that is made up of a (read only memory) and stores data of programs such as processing to be described later with reference to FIG. Address decoder 5 of this program memory 5A
The instruction (instruction) stored in the address designated by B is decoded by the instruction decoder 6,
The decoder 6 controls each part of the electronic device in synchronization with a predetermined timing clock.

The data stored in the data memory 4 composed of, for example, a RAM is sent to the arithmetic logic unit (ALU) 9 via the data bus 10 to perform arithmetic processing, and the result is sent via the data bus 10 to the data memory. 4 is stored again or the data stored in the data memory 4 is sent to the display decoder / driver 3 to cause the display 1 to display the data. It is assumed that character data of name and numeric data of telephone number are stored in a predetermined area of the data memory 4 in the order of Iwayo and registered.

The instruction decoder 6 scans the keyboard 2 through the output buffer 8,
When any key on the keyboard 2 is operated, the signal is taken in from the input buffer 7 and the data is stored in the data memory 4 via the data bus 10.
Further, the data is decrypted and the processing corresponding to each key is executed according to the processing procedure by the program of the program memory 5A.

Next, the data search processing by this electronic device will be described with reference to the flowchart of FIG. Step S in FIG.
Reference numeral 1 is a display process for selecting and displaying data to be displayed on the data memory 4 of FIG.

Next, it is judged in the key judgment step S2 whether or not a key input is made. If there is no key input, the process returns to the step S1 and the steps S1 and S2 are repeated.

If there is a key input in step S2, the process proceeds to step S3, it is determined what kind of processing is performed by the input key, and the result is determined in steps S4 and S5.
Alternatively, the processing from S6 onward is performed.

Step S4 is a routine for data input and other processing. In the data input process, for example, when inputting the data of the name and the telephone number in the telephone directory mode, first,
After selecting whether to write the name data in alphabet or kana by using the Kana / English / Numeric key 22, the character key group 23
Input the character data of the name. After that, the cursor movement key 29 is used to move a cursor (not shown) of the display 1 to the numerical data display section 1b to enter a numerical value into the character key group 2
Input the numeric data of the telephone number by 3.

Further, step 5 is a data write processing routine, which writes the character or numeric data input in step S4 to the data memory 4.

On the other hand, step S6 and the subsequent steps are the search processing routine, and if it is determined in step S3 that the search key 21 has been input, the process proceeds. First, in step S6, it is determined whether or not the search performed this time is a label search. That is, the search key 21
It is determined whether or not the label character data has been input immediately before the input of.

As a result of the discrimination, if it is a label search, the process proceeds to step S7, and the head address of the data memory 4 in which the registration data written in step S5 is stored is an address counter (not shown) provided in the data memory 4. Then, it is determined whether or not the initial letter of the data stored at the above address and the label letter match (step S8). This judgment can be made based on whether or not the numerical value of the code of the label character is equal to the numerical value of the code of the initial character of the data.

If the decision result in the step S8 is YES, the process proceeds to a step S9, the data of the address in the data memory 4 is called and a process for displaying the data on the display 1 is performed, and then the process returns to the step S1 to perform the display process. The above data is displayed.

If the result of the determination in step S8 is NO, the process proceeds to step S10, in which it is determined whether or not the search on the data memory 4 is overkill, that is, the initial letters of the data to be compared are labeled in the character order (aiueo order). It is determined whether the character has become a character after the character. This is determined by whether or not the code numerical value of the initial character of the data is larger than the code numerical value of the label character.

If the determination result is NO, step S1
Since the next data is called with 1, the address counter of the data memory 4 is incremented by 1, and the process returns to step S8 and step S8.
The following processing is repeated. In other words, steps S8 → S10 → S11 are performed until it is determined that the data matching the label character is found, or the search goes too far without the data matching the label character (there is no corresponding data even if the subsequent data is searched). → Repeat S8 ...

When the code numerical value of the initial letter of the data becomes larger than the label character for the first time (step S10), the message "Arimasen" for notifying that there is no corresponding data is displayed as the label search result in step S12. Perform processing for sending out, then step S1
Then, the message is displayed.

On the other hand, if the determination result in step S6 is not a label search, that is, a sequential search, the search key 21 is pressed without performing a label search, or the search key 21 is immediately after the label search. If is pressed, the process proceeds to step S13, and it is determined whether or not the present is just after the label search.

If the result of determination in step S13 is that the label has just been searched, processing advances to step S9, processing is called to display registered data at the address indicated by the address counter of the data memory 4, and then processing returns to step S1. The registration data of is displayed. Here, if there is corresponding data in the label search immediately before that, the corresponding data is displayed, and if there is no corresponding data, the data that has just been over-searched in the determination of step S10, that is, the registered data in the data memory 4 is displayed. In, the data next to the label character in the character order, that is, the first data after the label character with the first character closest to the label character is displayed.

If the result of determination in step S13 is not immediately after label search, the address counter of the data memory 4 is incremented by 1 in step S14, and then step S15.
It is determined whether or not the registered data to be searched ends. If the data has not ended, the process proceeds to step S9, the next data designated by the address counter of the data memory 4 is called, and the data is displayed in the following step S1.

In this way, each time the search key 21 is input, the data is sequentially called and displayed. When the data has ended in step S15, a preparation process for displaying a data end message is performed in step S16, and the process returns to step S1 to display the message.

By the above-mentioned processing, when the search key 21 is pressed to perform the sequential search after the label search, if there is the corresponding data in the preceding label search, the subsequent data is sequentially searched from the corresponding data, If there is no corresponding data, subsequent data is sequentially searched from the data next to the label character.

According to the present embodiment as described above, for example, when it is desired to retrieve the data of the name starting with "TO", "TO" is used as the label character in the rotary system as described above, and the character key 26 of FIG. 1 is operated five times. Instead of inputting with, enter "Ta" with a single operation of the character key to perform label search,
It is only necessary to search the data of “TO” by the order search from the data of the search result (the corresponding data of “TA” or the next data). In the past, this could not be done because the label search returns to the initial state when there is no corresponding data.

As described above, according to this embodiment, the label search and the order search can be combined to perform the search very efficiently with a simple key operation.

In the processing of FIG. 3, if there is no corresponding data in the label search, "Arimasen" is displayed as it is, and the data next to the label character is not displayed unless the search key 21 is pressed again. However, even if the search key 21 is not pressed, "arimasen" may be displayed for a certain period of time and then the next data may be automatically displayed.
The processing procedure in that case will be described below with reference to the flowchart of FIG.

Since steps S1 to S11 of FIG. 4 are the same as the processing of FIG. 3, description thereof will be omitted, and step S12 and subsequent steps will be described. If the label search goes too far in step S10 and the determination is yes, the process proceeds to step S12,
The display processing of the message "Arimasen" is performed. Then, in order to display this message for a fixed time, for example, about 1 second, the timer measures the fixed time in step S13.

After that, the process proceeds to the above-mentioned step S9, at which time the registration data designated by the address counter of the data memory 4, that is, the data next to the label character in this case, is called, and the process returns to step S1 to display the data. ..

After that, when the search key 21 is pressed and the determination in step S6 is NO, the process proceeds to step S14, the address counter of the data memory 4 is incremented by 1 to set the address of the next data, and the registered data is stored in step S15. Until the end, steps S9, S1 to S3, S6, S1
By repeating the processing of 4, the subsequent data is sequentially called and displayed according to the depression of the search key 21. Step S15
When the data ends in step S16, a preparation process for displaying a data end message is performed in step S16, and the message is displayed in step S1.

By such processing, when there is no corresponding data in the label search, the data next to the label character can be automatically displayed after "arimasen" is displayed for a certain period of time.

[0043]

As is apparent from the above description, according to the present invention, in the electronic device configured to perform the sequential search and the label search as described above, the label search is performed to find no corresponding information. , If you want to search sequentially,
Since the sequential search is performed from the character information next to the label character or the character string in the registered information stored in the storage means in the character order, even if the corresponding information is not found by performing the label search, the registered information In order to perform an order search from the character information next to the label character or the character string in the character order, it is possible to combine the label search and the order search and perform the search efficiently with a simple operation. can get.
