Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic device having a function of storing and retrieving information such as a so-called electronic memo.

(Prior Art) Recent electronic devices such as electronic memos have a function of recording information such as telephone numbers and schedules.

For example, the telephone directory function of conventional electronic devices,
It was possible to input the name and phone number.

In such electronic devices, it is essential to be able to efficiently recall recorded data. Here, calling data means
This refers to reading data from a storage device and displaying it on a display device.

Conventional calling methods in this type of electronic equipment are broadly classified into sequential search and direct search. The former method is to sequentially recall data in a storage device in the order in which it is stored. On the other hand, in the latter case, for example, when a user inputs a name used as a search key, data whose name item matches the input name is searched in the storage device and displayed. There are also known electronic devices that can perform a prefix match search to search for data that starts with the name entered in the name field.

(Problem to be Solved by the Invention) In conventional electronic devices, the call processing mode is such that sequential search and direct search are performed completely independently, or the state is automatically changed to sequential search after direct search is completed. It was either going back to . For this reason, the user cannot utilize the results obtained by the sequential search for a direct search, and has had to re-enter a search key such as a name for the direct search. Furthermore, in order to shift from direct search to sequential search, it was necessary to wait for the direct search to be completely completed.

Furthermore, in most conventional electronic devices, it is only possible to change the search key while a direct search is being performed. In some other electronic devices, when one piece of data is called up in a direct search, the direct search sometimes ends automatically. Therefore, the user
It was not possible to utilize the intermediate results of the direct search in subsequent searches. Additionally, if you want to check all the data after a certain piece of data, there is usually no other way than to use sequential search and view the data one by one from beginning to end.

The present invention has been made in view of the current situation, and allows the results of call processing including sequential search and die reflex search to be easily used for subsequent direct searches, and enables arbitrary The purpose is to provide electronic equipment that can transition to sequential search at the point in time.

(Means for Solving the Problems) The electronic device of the present invention includes a display means, a first storage means in which registered data is stored, at least one input key, and data used as a search key when calling data. a second storage means for storing, if the data in the second storage means is not an empty string, recalling data that at least partially matches the data; calling means for calling data stored in the storage means in a predetermined order; and when a predetermined key among the input keys is operated, at least a portion of the data displayed on the display means is transferred to the second storage. and means for storing an empty string in the second storage means when a predetermined key of the input keys is operated during the calling process by the calling means, This achieves the above objective.

(Example) The invention will now be described with reference to examples.

FIG. 1 shows the configuration of an embodiment of the present invention. This example is
Although the electronic memo can have many functions, in order to simplify the explanation, it will be described below as having only three functions: a schedule function, a telephone directory function, and a calculator function.

Each part of this embodiment shown in FIG. 1 will be explained. The CPUI controls the entire electronic device by executing a program stored in the program ROM 2. The work RAM 3 is a RAM used as a work area when the CPU 1 performs processing. C, G, ROM
4 is a ROM that stores character patterns for display.

The display unit 5 is composed of an LCD, and is a part that displays symbols such as characters and figures, and in this embodiment, 12 digits x 2
It has the number of characters displayed in the column. The upper part of the display section 5 is a dot part 5a in which one character is made up of 5.times.7 dots, and the lower part is a segment part 5b in which one character is made up of 7 segments (see FIG. 8, etc.). The LCD driver 6 is a part that converts the character pattern in the display RAMT into an electrical signal for driving the display section 5 and supplies it to the display section 5. Each bit of the display RAM 7 corresponds to one pixel of the display unit 5, and when a display pattern is set in the display RAM 7 by the CPU, the display pattern is converted into an LCD drive signal by the LCD driver 6. The information is sent to the display section 5, and the display state of the LCD of the display section 5 is updated.

The communication unit 8 is a part that transmits and receives data to and from other devices. The key part 9 is provided with a large number of keys, and is a part that detects the presence or absence of human keystrokes and transmits the result and the type of key operated to the CPUI. The types of keys in this key portion 9 will be described later. The data RAM 10 is a part that mainly stores data registered by the user, and the user data storage part 10c stores the user's data.
Data entered by the user and user data storage section
A human output buffer 10 as and a user data storage unit 10 c that temporarily store data called from Oc.
Data management area 1 for managing data stored in
It has 0b.

FIG. 2 shows details of the data RAM10. In this embodiment, the user is on the 2nd floor! type data, that is, telephone directory data (hereinafter sometimes referred to as location data) and schedule data (hereinafter sometimes referred to as SCHD data) can be registered. The location data consists of three parts: a name part, a company name part, and a number part. 5CHD
The data is composed of six parts: a business part, a flat part, a peripheral part, an eight part, a time part, and a needle part. The area from the flat part to the sealing part is indicated by reference numeral 105 in FIG. The human output buffer 10a temporarily stores the contents of each of these parts, including a name part lot, a company name part 102, a number part 103, a message part 104, and a year/month/day/hour/minute part. It has 105 areas. Data management area 10b
The number of bytes used/remaining bytes section 106 contains the number of bytes of the area already used by the user in the user data storage section 10c (that is, the number of bytes of the storage data section 109 and the number of bytes of the SCHD data section 110, which will be described later). ),
and the number of bytes of the free area 111, which will be described later. The location data number/5CHD data number section 107 stores the number of data registered as location data or 5CHD data. Reference numeral 10g indicates an area for other data necessary for managing the memory. The user data storage section 10C includes a location data section 109 that stores data registered as location data, and an S CHD data section 1 that stores data registered as 5CHD data.
It has 10. Furthermore, the free area 111 is an unused storage area. Since the location data and 5CHD data are data of undefined length, the number of occupied bytes per 1 data is not determined. Therefore, the position data section 109 and S C
Both HD data sections 110 are dynamically allocated,
It expands and contracts as new data is registered and deleted. In these data sections, there is no space between data, and the data is always stored in a left-justified format. Furthermore, regarding the order of the registered data, the location data is stored in the alphabetical order of the name section, and the 5CHD data is stored in the ascending order of the year, month, day, hour, and minute.

Some of the keys provided on the key part 9 are shown in FIG. The functions of these keys will be briefly explained.

The function key 31 functions as a so-called r2nd FUNCTIONJ key that gives a second function to other keys, and is a key that is pressed before operating each key as necessary. M
The ODE key 32 is used to select a desired mode from among three modes: a display mode, an SCHD mode, and a CAL mode for executing the telephone directory function, schedule function, and calculator function, which are the main functions of this embodiment. This is the key for selection. The ON/C key 33 functions as a normal power key when the power is off, and as a key for returning the display state to the initial state when 'F4+1j is already on. The OFF key 34 is a key for turning off the power of the device. The registration key 35 is a key for registering data input by the user in the user data storage unit lOc. The calling cow-36 is the user data storage unit 10c.
This key is used to call up data registered in and display it on the display unit 5. The communication key 37 is a key used when communicating with other sets. Memory check key 3
8 is a key used when it is desired to display the memory usage status. The delete key 39 is a key used to delete input characters, input data, and the like.

The character input keys 40 are a group of keys for inputting numbers (0-9), katakana, alphabetical characters (A-Z), and symbols (+, -, etc.), and are used when inputting characters, etc. Company Meite-42 is used when calling with a company name in the place mode.In other words, in this embodiment, in the place mode, there is a function to call data whose name starts with a match, and a function to call data whose name starts with a match. I have a name/
The company name key 42 is a key used to operate the latter function. The RES ET key 41 is a key for forcing the entire system into a certain state (temporarily referred to as a reset state). This key 41, unlike other keys, is directly connected to the hardware of the CPUI, and can operate the CPUI by interacting with it no matter what state the CPUI is in. In other words, the other keys are CPU1
No signal can be given to CPU 1 except when the CPU 1 requests input.

FIG. 4 shows a schematic flowchart of the processing in this embodiment. First, in this system, when the user does nothing, A P O (Auto Pow) is activated in step S1.
er 0ff) Waits for user's key input while counting. If there is no key input for a predetermined period of time, 'r4# is automatically shut off to save power. The APO count is a time count for this purpose. When any key is pressed, the key part 9 sends a signal indicating that the key is manually pressed and a code indicating the type of key pressed. The flow proceeds to key classification (step S2), where a process to be performed is selected according to the type of key pressed. Then, processing of the pressed key is performed in step S3.

In the various key processing routines in step S3, CP
U1 performs processing using the work RAM 3, communication section 8, data RAM 10, etc. according to the contents of the program ROM 2, and then the process proceeds to the display routine (step S4).
).

In the display routine, in order to display the digits instructed by the various key processing routines, the character pattern of the character to be displayed is taken out from the CGROM 4 and set in the display RAM 7 at the position of the digit to be displayed. The character pattern set in the display RAM 7 is converted by the LCD driver 6 into an electrical signal for driving the LCD, and displayed on the display section 5.

When the display process in step S4 is completed, the flow returns to step S1 to wait for the next key. ON/C key 3 when the power is off
If 3 is pressed, the flow is forced to step S5
It is now easier to start. At this point, the position mode is selected as the main function, and the process proceeds to step S6, the C key process (FIG. 5).

FIG. 6 shows the flow of C key processing. Here, the initial state of the currently selected mode is set, and then a display routine corresponding to the selected mode is selected and control is transferred thereto. The initial state of each mode is shown in FIG.

When the RESET key 41 is pressed, control is transferred to the steno knob S7 (FIG. 4) regardless of which state the flow is processing. Here, as shown in FIG. 7, all current states are abandoned and a reset state is set. And step S4
The process moves to the middle RESET display routine. FIG. 8 shows the reset display. The state shown in FIG. 8 is the data management area 10b of the data RAM 10 and the user data storage section 10c.
This state allows the user to select whether or not to initialize by erasing all user data stored in the .

Here, when a predetermined key representing rYESJ (registration key 35 in this embodiment) is pressed, all user data is erased. If a key other than the predetermined key is pressed, the erasure and initialization processing is not performed and the process moves to the C key processing (step S6).

Next, the processing of each key will be explained.

FIG. 10 shows the processing of the OFF key 34. OFF key 3
If 4 is pressed, the display on the display section 5 is erased and the T4 source of the system is turned off. This electronic memo will now stop working. However, since the data RAM 10 is operated by another f[, the user data registered in the data RAM IO will not be lost. Also, after turning off the system power, set the program counter in CPU1 to POWER-
Set it to the ON processing address. As a result, the next time the ON/C key 33 is pressed, the POWER
The process is started from the -ON process.

FIG. 11 shows the processing of the function key 31. When the function key 31 is pressed, display/non-display of the function symbol 13 disposed on the left side of the display section 5 is switched as shown in FIG.

FIG. 12 shows the processing of the character input keys 40, and FIG. 14 shows an example of character input using the character input keys 40. In this embodiment, about 100 types of katakana, alphabetic characters, numbers, and symbols can be manually written, and for this purpose, 17 keys are provided as the manual text keys 40. When any of the character input keys 40 is pressed (step 321), an internal code corresponding to the pressed key is generated. Then, the pointer indicating the current cursor position (that is, the position where a character is input) in the work RAMa is taken out, and
Write the above internal code at the position indicated by the pointer in 0a. The pointer used here to indicate the cursor position is initialized when the initial state of the mode is set, and is incremented each time a character is input. Then step S
At step 22, similarly to the display routine (step S4), the process moves to a routine in which the character code in the human output buffer 110a is developed into a character pattern using the C, G, and ROM 4, and written into the display RAM 7. FIG. 14 shows an example of inputting characters from the initial state of the text mode, and IB on the right side of the figure indicates a character string input to the name section in the input/output buffer 10a. FIG. 14(a) is the initial display, and at this time IBN
does not contain anything, that is, is NULL. Here, when the character "A" is input using the character input key 40, I
"A" is entered in BN, and the display becomes as shown in FIG. 14(b). Here, under par “” to the right of the “A” display.
-” is the cursor position (i.e. the position where the next character will be input)
shows. If "force" is further input, "force" is added to the IBN, and the display becomes as shown in FIG. 14(C).

FIG. 15 shows the processing when the MODE key 32 is pressed. When the MODE key 32 is pressed, it is first checked whether the function symbol 13 (FIG. 13) is lit (step 531). If the function symbol 13 is not lit, the type of function mode to be set next differs depending on the type of the current function mode (step 532).

That is, if the current function mode is the position mode, 5CHD
The mode is set (step 533), and if the current function mode is 5CHD mode, the CALA-mode is set (step 534), and if the current function mode is CALA-mode, the position mode is set (step 534). step 535).

Therefore, each time the MODE key 32 is pressed, the modes change cyclically in the order of position mode → 5CHD mode → CAL mode → position mode (this order is called the forward direction) as shown by arrow A in FIG. Can be switched sequentially.

If the function symbol 13 is lit (displayed), the process advances to step S36, and if the current function mode is the setting mode, the CALA-code is set (step S53).
7) If the current function mode is S CHD mode,
The function mode is set (step 338), and if the current function mode is CALA-mode, the SCHD mode is set (step 539). Therefore, MODE key 32
Each time is pressed, the mode is cyclically switched in the order of position mode -> CAL mode -> 5CHD mode - position mode (this order is referred to as the reverse direction) as shown by arrow B in FIG.

In this way, the MODE key 32 can be pressed without pressing the function key 31.
When operated, the mode is sequentially switched to forward direction A. On the other hand, when the function key 31 is pressed and the MODE key 32 is operated, the mode is sequentially switched in the reverse direction B. Therefore, when switching from setting mode to CALA mode, 5CHD
You can switch to CALA-mode without going through the mode. In this case, the MODE key 32 only needs to be pressed once.

The processing of the registration key 35 is shown in FIG. FIG. 17 shows an example of a procedure for registering data using the registration key 35 in the storage mode. In FIG. 17, the left side of the figure shows the character string or number string input by operating the character input key 40 when the registration key 35 is operated, and the right side of the figure shows the case where the operation or input is performed. The display contents of the display section 5 are shown.

First, when the name "Kobayashi" is input using the character input key 40 in the initial state shown in FIG. )). When the registration key 35 is pressed, the flow goes to step S.
Proceed to step 41. What you are currently inputting is the name part, so
Further, the process advances to step S43, and the input state of the number part is set. After that, the routine moves to display "Bangou?", and "Bangou?" is displayed in the dot section 5a (
Figure 17(C)). Phone number r03-123-4567
Enter J using the character input key 40. The input telephone number is displayed on the segment section 5b of the display section 5 (
Figure 17(d)).

If you press the registration key 35 again here, the flow will be 541-S.
42→344→S45, the input state of the company name section is set, and the process moves to the "Kaisha Mei?" display routine.

As shown in Figure 17(e), "(Kaishamei?)"
is displayed on the dot section of the display section 5. The parentheses are used here to avoid confusion between the input state of the company name section and the input state of the name section. FIG. 17(f) shows a state in which "Shaxx" is input as the company name.

If you press the registration key 35 in this state, the flow will be S41 → 8
42→344→S47. Input data "Kobayashi", "Shaxx" and r03-123-45
67J inputs the name part 101 and company name part 1 of the input/output cover sofa 10a by the character input key processing routine shown in FIG.
02 and the number section 103, respectively, and in step S47, these data are transferred as location data to the location data section 109 in the user data storage section 10c. At this time, the location data in the location data section 109 has the name section in iweo order (i.e., A→A-A-
The data is rearranged and stored in the order of Z-0→9→symbol. Furthermore, after the number of used bytes/number of remaining bytes and number of stored data items in the data management area 10b are updated,
The C key is processed and initialized. The input/output buffer 10a is cleared.

FIG. 18 shows the procedure for registering 5CHD data.

In this figure as well, as in Fig. 17, the left side of the figure shows the character string or number string input by operating the character input cow 40 when the registration key 35 is operated, and the right side of the figure shows the character string or number string input by operating the character input cow-40. This shows the display content on the display unit 5 when an operation or input is performed. From the initial state shown in FIG. 18(a), the year, month,
The date, hour, minute, and task are entered in this order. All of these data are stored in the human output buffer 10a, and the cursor is automatically advanced each time a character or the like is input. Figure 18 (
b) shows the state in which r1989J is input as the year.
C) is the same figure (
d) shows a state in which "12" hours and "35" minutes have been input. The year is displayed together with "year" in the dot section 5a. Month,
The day, hour, and minute are displayed in the segment section 5a. As shown in Figure 18(d), when the 1/1 digit number is input,
Data from the year to the minute is temporarily stored in the area 105 of the crowded hippopotamus sofa 10a. The year display in the dot section 5a is erased, and "YOU KEN?" is displayed instead. When "party" is input as the business data, the character string "party" is displayed in the dot section 5a (FIG. 18(d)). This task data is stored in the task section 104.

Here, when the registration key 35 is pressed, step 3 in FIG.
Processes 41 and 346 are performed. In step 346, non-standard data (for example, "
A check is made to see if there is a month (13th month, 40th day, 25th hour, 90th minute). If there is data that is not specified, the process proceeds to the "Date and time is incorrect!" display routine, and "Date and time are incorrect!" is displayed in the dot section 5a (
Figure 19).

If there is no problem with the data from year to minute, the process advances to step S47, and the same storage process as in the case of the above-mentioned location data is performed. The 5CHD data is stored in the 5CHD data section 110 in ascending order of year, month, day, hour and minute.

The process when the company name key 42 is operated will be explained with reference to FIG. 20. When the company name key 42 is pressed in the 5CHD mode or the CAL mode, a transition is made to a state in which the key is waiting for human power (step S51). If the company name key 42 is pressed in the setting mode, it is determined in step S52 whether or not the electronic device is in the process of inputting company name data. If company name data is being input, the electronic device is placed in the name data input state in step S55, and the
Control is passed to the display routine.

If company name data is not being input, step S54
The electronic device is put into the state of inputting company name data and moves to the "Kaisha Mei" display routine.

In FIG. 24, which will be explained in detail later, the transition from the display state shown in FIG. 24A to the display state shown in FIG.

Next, with reference to FIGS. 21A, 21B, and 22 to 24, a process of reading and displaying registered data, that is, calling data will be described.

Data can be retrieved using the retrieval key 36 or the like. In the following, we will explain using the example of calling the stored data.
It is assumed that the position data shown in FIG. 22 has been registered.

FIGS. 21A and 21B show the processing when the call key 36 is pressed. First, in step S61, it is determined whether or not calling processing is in progress. If the call is not in progress,
In step S62, it is determined whether or not the company is under human resources. If the company is under human resources, 1 is assigned to the variable KS (step 564), and if the company is not on human resources, 0 is assigned to the variable KS. (Step 563). The variable KS is a company name call flag, and KS=1 indicates that a call is performed using the input company name as a key.

The character string of the name or company name input and stored in the human output buffer lOa is saved to an area called DSSTR provided in the work RAMa (step 5).
65). The character string in the area DSSTR is used as a key for data retrieval. If no name or company name is entered, DSSTR is an empty string (N
ULL). Next, in step S66, the presence or absence of registered data in the currently selected mode (for example, position mode) is checked, and if there is no registered data, the process moves to the C key. If there is registered data, the address of the first data in the registered data is set to pointer DA (
Step 868), the process moves to step S76.

If it is determined in step S61 that data is being recalled, in step S69 it is determined whether the function symbol 13 (see Figure 13) is displayed (lit state) or not (non-lit state). It is determined. If the lighting is off, the process moves to step S73. If the lighting is on, the process moves to step S73.
The value of the variable KS is checked in step 70, and if KS=O, the area DSSTR is cleared (step 571), and if KS=1, the character string displayed in the dot part 5a is cleared in the area D.
After updating the contents of the area DSSTR by saving to SSTR (step 572), the process moves to step S73. To explain the processing in steps S71 and S72, if a direct search is being performed using the input name, if the call key 36 is pressed with the function symbol 13 lit, the processing in step S71 will be executed. , the direct search process will be canceled and a sequential search will be performed. If a direct search using a company name is being performed, when the call key 36 is pressed with the function symbol 13 lit, the character string used as the search key is displayed through the process of step S72. will be replaced with the company name.

In step S73, it is checked whether there is data following the data pointed to by pointer DA, and if there is data, the address of that data is set in pointer DA (step 574). If there is no next data, the calling process ends and the C key process is performed.

After a new address is set in the pointer DA in step S74, the area DSSTR is set to NUL in step S76.
It is determined whether it is L or not. Area DSSTR is NUL
If it is L, the data pointed to by the pointer DA in the steno knob S80 is transferred to the input/output cover sofa 10a.

If the area DSSTR is not NULL, step S
At 77, the value of variable KS is examined. If KS=0,
In step 378, the contents of the name part of the data pointed to by pointer DA start with the character string in area DSSTR (
It is determined whether or not the condition (first half matches) is satisfied. If KS=1, it is determined in step S79 whether or not the condition that the contents of the company name part of the data pointed to by the pointer DA starts with the character string in the area DSSTR (first match) is satisfied. be done. If the above-mentioned conditions are satisfied in step S79 of step knob 378, the data pointed to by pointer DA is transferred to human output buffer 10a in step S80. The data transferred to the human output buffer loa is displayed in a display routine. If the above conditions are not satisfied in steps 378 and S79, the process returns to step S73, and the next data is examined according to the procedure described above.

FIG. 23 shows an example of a data retrieval procedure using an input name as a search key. The keys to be operated are shown on the left or right sides of FIGS. 10A to 1G, and the display results corresponding to the key operations are shown in the center. The character "i" is inputted (FIG. 23(b)) while a display prompting the user to enter a name is displayed (FIG. 23(a)). When the caller-36 is pressed, the character string "I" is set in the area DS S TR, and as shown in FIG. (See Figure 22) is displayed. When the call key 36 is pressed again,
The next set data ■ whose name part starts with "a" is displayed (FIG. 23(d)). When the call key 36 is further pressed, there is no longer any data whose name portion starts with "i", so the call process is completed and the display shown in FIG. 23(e) is displayed. When the function key 31 and call key 36 are pressed in the state shown in FIG. 23(d), the area DSSTR is set to NULL and a sequential search is performed. Therefore, the data ■ immediately after the position data ■ displayed in FIG. 23(d) is displayed (FIG. 23(f)). As described above, in this embodiment, by pressing the function key 31 and the call key 36 while a direct search using a name as a search key is being performed, the state of the direct search is canceled and the sequential search is started. Migration is done easily.

FIG. 24 shows an example of a data retrieval procedure using an input company name as a search key. The keys to be operated are shown on the left side of (8) to (g) of the same figure, and the display results corresponding to the key operations are shown in the center. When the company name key 42 is pressed while a display prompting the user to enter a name is displayed (FIG. 24(a)), the user is prompted to enter the company name as shown in FIG. 24(b). No. 24 '4 (c) is the letter "
This shows a state in which "" has been input. When the call key 36 is pressed, the character string "shi" is set in the area DS STR, and the contents of the company name section are changed to "shi" as shown in FIG. 24(d).
The first position data (see FIG. 22) starting with "" is displayed. When the call key 36 is pressed again, the screen shown in FIG. 24 (
As shown in e), the next data ■ whose company name section starts with "shi" is displayed. When the function key 31 and the call key 36 are pressed here, the company name "XXJ" being displayed is set in the area DSSTR, and the next setting data ■ whose contents of the company name section start with "XX" is displayed. Ru. When the call key 36 is further pressed, the contents of the company name section will be changed to "Shaxx".
Since the data starting with no longer exists, the calling process ends and the display shown in FIG. 24(g) is produced. Furthermore, the second
Although not shown in Figure 4, as can be seen from the flowcharts in Figures 21A and 21B, a sequential search by company name is first started, and when data containing an appropriate company name is retrieved, it is displayed. You can also move to a direct search using the company name as the search key.

In the above embodiment, the location data had three items: name, phone number, and company name, but the present invention is not limited to this, and items such as blood type and date of birth may be added. You can also do it.

(Effects of the Invention) In the electronic device of the present invention, the data that is called up and displayed can be used as a search key in subsequent calls in direct search.

Therefore, regardless of whether the search is sequential or direct, the user can retrieve data using a newly set search key without interrupting the retrieval process and re-entering the search key. It can be carried out.

In the electronic device of the present invention, the user can also perform a sequential search by performing an appropriate key operation at any time when performing a direct search.

For example, in the electronic device of the present invention that has a telephone directory function and allows input of company name data, when calling up data on a person in a certain company, the user first enters the first character of the company name using the search key. Perform a data call as
When the person data of the target company is called up, the calling process can be easily performed using the displayed company name as a search key. In this way, only the data of the person of interest in the company is subsequently called up.

Furthermore, the electronic device of the present invention is effective even when the user does not accurately remember the data that he or she wants to use as a search key. That is, if you have accurately memorized only the first few characters of the name of the target company, you can first input those characters as a search key.
