In b, various user messages registered by the above-described registration process are stored with a date and a period as display conditions.

FIG. 7 is a flowchart showing the operation of the message display process in the embodiment. When the power of the device is turned on (step B11), the CPU 11 performs the process of extracting the message displayed on the first line of the message screen shown in FIG. 5 and the process of extracting the message displayed on the second line of the message screen (FIG. 5). Steps B12 and B13). Here, the extraction processing of the first line message is shown in FIG. 8, and the extraction processing of the second line message is shown in FIG.

(First Line Message Extraction Process) In the first line message extraction process, as shown in the flowchart of FIG. 8, the CPU 11 first determines whether or not the device is activated for the first time on that day (step C11). ). This is RA
This is performed by checking the usage status information stored in the usage status storage area 13a of M13. That is, the usage information indicates the date and time when the device was last used. Therefore, from the last use date and time and the current date and time (obtained by the real timer 19), it can be determined whether or not the device has been started for the first time on that day.

If the device has not been activated for the first time on that day (Yes in step C11), the CPU 11 reads the use status information and determines whether the use status of the device is "10 days or more" / "10 days or less" / "Yesterday.""Use" is checked (step C12). Then, the CPU 11 sends a message having the use status as a display condition to the ROM 1.
It is extracted from the second fixed message storage area 12b (step C13). In this case, as shown in FIG.
"It's been a long time! It's been a long time! I'm glad to meet you!", "If you're within 10 days", "I'm fine!" The message will be extracted.

On the other hand, if the device has not been activated for the first time on the day, that is, for the second time or later (step C).
11), the CPU 11 reads the current date and time from the real timer 19, and checks whether the use time of the device is "morning" / "afternoon" / "night" / "midnight" (step C14). Then, the CPU 11 extracts a message having the use time as a display condition from the fixed message storage area 12b of the ROM 12 (step C1).
5). In this case, as shown in FIG.
In this case, messages such as “Good morning!”, “In the afternoon”, “Hello!”, “Nighttime” and “Good evening”, and “Midnight” in “Hello” are extracted.

(Extraction Processing of Second Line Message) In the extraction processing of the second line message, as shown in the flowchart of FIG. 9, the CPU 11 first determines whether or not there is user registration (step D11). This is determined by accessing the registration message storage area 13b of the RAM 13. That is, this registration message storage area 1
If a user message is stored in 3b, it is determined that there is user registration.

If there is a user registration (Yes in step D11), the CPU 11 checks the display conditions of the user message stored in the registration message storage area 13b, and determines whether there is a message that matches the current date in the display conditions. A search is made for whether or not there is (step D12). As a result, if there is a user message that matches the current date (Yes in step D13), the CPU 11 gives the highest priority to the user message and extracts it from the registered message storage area 13b (step D14). In this case, as shown in FIG. 4, if the current date is “January 10,” for example, a user message such as “Today is my daughter's birthday” is extracted.

On the other hand, when there is no user registration (step D
11) or if there is no user message that matches the current date (No in step D13),
The CPU 11 checks the display conditions of the day-limited message and the period-limited message stored in the fixed message storage area 12b, and searches whether there is a message that matches the current date (step D15). As a result, if there is a date limited message that matches the current date (Yes in step D16), the CPU 11 extracts the date limited message from the fixed message storage area 12b (step D17). In this case, as shown in FIG. 3A, for example, if the current date is “January 1”, a day limited message such as “Happy New Year” will be extracted.

If there is a time-limited message that matches the current date (No in step D18), the CPU 11
Randomly extracts the time-limited message or the general message from the fixed message storage area 12b (step D19). In this case, as shown in FIG. 3B, if the current date is “January 2”, for example, a limited time message such as “Do you want to go for the first time?”
Alternatively, one of the various general messages shown in FIG. 3C is randomly extracted.

It is assumed that the date of the date limited message and the date of the period limited message are set so as not to overlap. If there is no time-limited message that matches the current date (No in step D18), the CPU 11 randomly extracts a general message from the fixed message storage area 12b (step D19). In this case, FIG.
One of the various general messages shown in (c) is randomly extracted.

When the first line message and the second line message are extracted in this way, the CPU 11 displays them on the first line and the second line of the message screen shown in FIG. 5 (step B14). After the display, the CPU 11 stores the usage status information stored in the usage status storage area 13a of the RAM 13 in preparation for the next message display.
9 is updated based on the current date and time obtained from Step 9 (Step B15).

As described above, when the device is started up, two types of messages are displayed on the message screen shown in FIG. In this case, a greeting message is displayed as a message on the first line of the screen, and when the power is turned on for the first time on the day, a message according to the usage status of the device, and the second and subsequent times, according to the usage time of the device. Since the message is displayed, the pleasure of using the device can be brought out.

In the second line, a message limited to a day, a message limited to a period, or a general message is displayed as a message according to the season, so that daily life information can be obtained.

Further, since the message registered by the user is displayed on the second line with the highest priority, the information can be used as a scheduler by registering personal schedule information in advance.

In the above embodiment, the message is displayed when the power is turned on (when the device is started up). However, the message can be displayed at an arbitrary timing by providing the message display instruction means. In this case, by displaying information different from that at the time of starting the device, a refresh effect for the device user can be expected.

Further, by providing a means for detecting that no key operation has been performed for a certain period, a message can be displayed in an idle state. In this case, by displaying information different from that at the time of starting the device, a refresh effect for the device user can be expected.

In the above-described embodiment, a case is assumed where a character string is displayed as a message. However, for example, a mark, an image (still image), an animation (moving image), and audio data can be output as a message. is there. However, in the case of audio data, it is necessary to provide audio output means. With such a configuration, the enjoyment of using the device and the variety of information to be provided can be further enhanced.

The method described in the above-described embodiment includes, as programs that can be executed by a computer, for example, a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM,
It is also possible to write the data on a recording medium such as a DVD or a semiconductor memory and apply it to various devices, or to transmit it via a communication medium and apply it to various devices.
