PURPOSE:To also store data concerning year as time data by defining one of display means as a dot matrix display device, displaying the prescribed part of schedule data in the dot matrix display device and displaying the other part of the schedule data in the display means. CONSTITUTION:A display part 5 is composed of an LCD and defined as a part to display characters or symbols. The upper step of the display part 5 is a dot part 5a, in which one character is 5X7 dots, and the lower step is a segment part 5b in segment constitution. By an LCD driver 6, a character pattern in a RAM 7 for display is converted to an electric signal for driving the display part 5 and applied to the display part 5. Each bit of the RAM 7 for display is respectively correspondent to each picture element of the display part 5. When the signal of a display pattern is set to the RAM 7 for display by a CPU 1, the signal is converting to the driving signal of the LCD by the LCD driver 6 and sent to the display part 5 and the LCD of the display part 5 is turned on. Thus, the data concerning year can be stored as the time data.

Description

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

(Prior Art) Many electronic memos and the like have a function of storing data for schedule management. For this purpose, the contents of the business and the time data (month, day, hour, minute, etc.) of the business are stored in combination and recalled on the display section as necessary.

When storing schedule data in an electronic memo, etc.,
Normally, the data to be stored (contents of the business and time data) is displayed on the display unit by operating a key, and after the displayed contents are confirmed, the process is performed to store the data in the storage device. On the other hand, since the size of a portable electronic device such as an electronic memo is limited, the display section cannot be made large. In order to make the display section as small as possible, it is necessary to use a two-stage structure consisting of a dot section mainly for displaying character strings and a 7-segment section suitable for displaying numeric strings. The contents will be displayed in the dot section, and time data that can be expressed as a number string will be displayed in the 7 segment section.

(Problems to be Solved by the Invention) As described above, since the size of the display section is restricted, the number of digits displayed on the display section is not large, and the number of digits of data displayed on the display section is also limited. Therefore, with conventional electronic memos,
Only data related to the month, day, hour, and minute are treated as time data, and data related to the year cannot be stored as time data.

Incidentally, the schedule data group is arranged in time order (that is, in chronological order) and stored in the storage device. When displaying the schedule data on the display section, each schedule data item is sequentially displayed on the display section according to the order of the time data.

Therefore, in conventional electronic memos and the like that are arranged based on time data that does not include the year, schedule data may be displayed in a different order from the actual chronological order, which may cause confusion.

In other words, if schedule data for December of a certain year and schedule data for January of the following year are mixed in the stored schedule data group, the data 1 is actually the later data. Monthly schedule data is displayed first.

An object of the present invention is to provide an electronic device that can also store data related to the year as time data without increasing the size of the display section.

(Means for Solving the Problems) An electronic device of the present invention has a function of storing schedule data and is equipped with at least two types of display means, one of which is a dot matrix display. A device, comprising means for displaying a predetermined portion of schedule data on the dot matrix display device and means for displaying another portion of the schedule data on another display means, thereby achieving the above object. .

Preferably, the schedule data includes year data in addition to data regarding month, day, hour, and minute.

Preferably, the predetermined portion of the schedule data is year data, and the other portion is month, day, hour, and minute data.

It is preferable that the data displayed on each of the display means described above can be stored as schedule data.

Further, the other display means may be a segment type display device such as a 7-segment display device.

(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 is a part that controls the entire system, and controls the entire system according to the contents of the processing programmed in the program ROM 2. The work RAM 3 is a RAM used as a work area when the CPUI performs processing. C. G. ROM4 is a ROM that stores character patterns for display.

The display section 5 is constituted by an LCD, and is a section for displaying characters and symbols, and in this embodiment has a number of displayed characters of 12 digits x 2 columns. In the upper row of display section 5, each character is 5 x 7.
This is a dot portion 5a of dots, and the lower part is a segment portion 5b having a seven-segment configuration. The LCD driver 6 is a part that converts the character pattern in the display RAM 7 into an electrical signal for driving the display section 5 and provides the electrical signal to the display section 5 . Each 1 bit of the display RAM 7 corresponds to one pixel of the display section 5, and the display R
When a display pattern signal is set in AM7, the signal is converted into an LCD drive signal by the LCD driver 6 and sent to the display section 5, causing the LCD of the display section 5 to light up.

The communication section 8 is a section 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 RAMIO is a part that mainly stores data registered by users, and is a user data storage part 10c, which stores user data.
A human output buffer 10a that temporarily stores data input by the user and data retrieved from the user data storage unit 10c, and a user data storage unit 10
It has a data management area 10b that manages data stored in c.

FIG. 2 shows details of the data RAMIO. In this embodiment, the user can register two types of data: telephone directory data (hereinafter referred to as TEL data) and schedule data (hereinafter referred to as SCHD data). TEL data consists of three parts: a name part, a company name part, and a number part. SC}{D data is composed of six parts: a business part, a year part, a month part, a date part, a time part, and a division part. The area from the year part to the part part is indicated by reference numeral 105 in FIG. Human output buffer 10
a temporarily stores the contents of each of these parts, including a name part 101, a company name part 102, a number part 103,
It has a business section 104 and a year/month/day/hour/minute section 105. The used byte number/remaining rebyte number section 106 of the data management area 10b includes the number of bytes of the area already used by the user in the user data storage section 10c (i.e., the number of bytes of the TEL data section 109 and the S CHD data section, which will be described later). 110) and the number of bytes of the free area 110, which will be described later. Number of TEL data/S
The CHD data number section 107 includes TEL data or SCH
Stores the number of data registered as D data. Reference numeral 108 indicates an area for other data necessary for managing the memory. User data storage unit 10
c has a TEL data section 109 that stores data registered as TEL data, and an SCHD data section 110 that stores data registered as SCHD data. Further, the vacant area 111 is an unused area. Since TEL data and SCHD data are data of undefined length, the number of bytes occupied per data is not determined. Therefore, TEL data section 109 and SCHD
The data section 110 is dynamically allocated and expands and contracts as new data is registered and deleted. In those data sections, there is no space between data, and the data is always stored in a left-justified format. Furthermore, regarding the order of registered data, TEL data is stored in alphabetical order of the name section, and SCHD data is stored in ascending order of 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 operates in a telephone directory mode (hereinafter referred to as TEL mode), a schedule function mode (hereinafter referred to as SCHD mode), and a calculator function for respectively executing the telephone directory function, schedule function and calculator function, which are the main functions of this embodiment. This key is used to select a desired mode from among three modes (hereinafter referred to as CAL mode).

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 the power is already on. The OFF key 34 is a key for turning off the power source of the device. Registration key 3
5 is a key for registering data input by the user in the user data storage section 10c. The call key 36 is a key for calling up data registered in the user data storage section 10c and displaying it on the display section 5. The communication key 37 is a key used when communicating with other sets. The memory check key 38 is a key used when it is desired to display the memory usage status. Delete key 3
9 is a key used to erase input characters, input data memory, etc.

The character input keys 40 are a group of keys for inputting numbers (O to 9), katakana, alphabets (A to Z), and symbols (+, 1st, etc.), and are used when inputting characters. Name/company name-42 is a key used in TEL mode. This key 42 will be explained in detail later. R E S E
The T key 41 is a key for forcibly setting the entire system to a certain state (temporarily referred to as a reset state). Unlike other keys, this key 41 is directly connected to the hardware of the CPUI, and can operate the CPU 1 by inclining whatever state the CPUI is in. In other words, other keys cannot provide signals to the CPUI except when the CPUI 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 Po
(Wer Off) Waits for the user's key power while counting. If no key is pressed for a predetermined period of time, the power will be 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 32), where a process to be performed is selected according to the code of the pressed key. Then, processing of the pressed key is performed in step S3. In the various key processing routines in step S3, the work RAM 3 is
, the communication unit 8, the data RAM 10, etc., and then proceeds to a 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 31 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. Here, the TEL mode is selected as the main function, and the process proceeds to step S6 (FIG. 5).

FIG. 6 shows the flow of C key processing. Here, an initial state is set for the currently selected mode, 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 step 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
Move to the middle RESET display routine. FIG. 8 shows the reset display. The state shown in FIG. 8 is the data management area 10b and user data storage unit 10C of the data RAMIO.
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 system is turned off. This electronic memo will now stop working.

However, since the data RAMIO is operated by a separate power source, the user data registered in the data RAMIO will not be lost. Also, after turning off the system power, set the program counter in cPU1 to POVER-O.
Set it to the address for N processing. This is then ON
This is because when the /C key 33 is pressed, the process starts from the POWER-ON process.

FIG. 11 shows the processing of the function key 31. When the function key 31 is pressed, the function symbol 13 on the left side of the display section 5 is inverted, 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, approximately 100 types of katakana, alphabets, numbers, and symbols can be input, and for this purpose, 17 keys are provided as character input keys 40. When any of the character input keys 40 is pressed (step 321), a content code corresponding to the pressed key is generated. And work RAMa
A pointer indicating the current cursor position (that is, the position where a character is input) is taken out from within the turntable buffer 10a, and the above-mentioned internal code is written at the position indicated by the pointer within the turnout buffer 10a. 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. Thereafter, in step S22, the character code of the input/output buffer lOa is changed to C. G. The program moves to a routine in which the character pattern is developed using the ROM 4 and written into the display RAM 7. Figure 14 shows an example of inputting characters from the initial state of TEL mode.
indicates a character string input to the name section in the human output buffer 10a. FIG. 14(a) shows the initial display, and at this time, IBH contains nothing, that is, it is NULL. If you input the character "A" using the character input key 40, "A" will be entered in the IBN and the display will be as shown in FIG. 14(b).
become that way. Here, the underbar "1" to the right of the display of "A" indicates the cursor position (ie, the position where the next character will be input). Furthermore, if you enter "force", IBM
"Force" is added to , 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 S31). If the function symbol l3 is not lit, the type of function mode to be set next differs depending on the type of the current function mode (step S32).

That is, if the current function mode is TEL mode, SC
The HD mode is set (step S33), and if the current functional mode is the SCHD mode, the CAL mode is set (step S34), and if the current functional mode is the CAL mode, the TEL mode is set (step S34). S
35). Therefore, each time the MODE key 32 is pressed, the mode changes from TEL mode to S as shown by arrow A in FIG.
The mode is cyclically switched in the order of CHD mode→CAL mode→TEL mode (this order is referred to as forward direction).

If function symbol l3 is lit, step 33
Proceed to step 6 and if the current function mode is TEL mode,
If the CAL mode is set (step S37) and the current functional mode is SCHD mode, the TEL mode is set (step 838) and the current functional mode is CA.
If it is the L mode, the SCHD mode is set (step S39). Therefore, each time the MODE key 32 is pressed, the mode changes cyclically in the order of TEL mode → CAL mode → SCHD mode → TEL mode (this order is called reverse direction) as shown by arrow B in FIG. Can be switched sequentially.

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, T.E.
When switching from L mode to CAL mode, SC
You can switch to CAL mode without going through HD 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 TEL mode. In FIG. 17, the left side of the figure shows the character string or number string input by operating the registration key 35 or character input key 40, 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.

When calling a stored telephone number, the user can search using the name or company name as a key. The called telephone number is displayed in the segment section 5b, and the name or company name is displayed in the dot section 5a. In this state, if the name/company master key 42 is pressed, the displayed contents of the dot section 5a can be changed from the name to the company name and vice versa.

Instead of the company name, other data such as birthday or blood type may be stored.

FIG. 18 shows the SCHD data registration procedure.

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 registration key 35 or the character input key 40, and the right side of the figure shows the operation. Or, it shows the display contents of the display unit 5 when an 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 input/output buffer 10a, and the cursor is automatically advanced each time a character or the like is input. Figure 18 (
