The audio processing circuit 58 includes sockets 14 to 1
A predetermined audio signal is generated in response to an input from the CPU 6 or a command from the CPU 41 and output to the adder 59. The voice memory 61 is controlled by the CPU 41 and outputs a predetermined voice (for example, a warning sound “Eh?”) Stored in advance to the adder 59. The adder 59 adds the output of the audio processing circuit 58 and the output of the audio memory 61 and outputs the result to the speaker 9 via the audio volume controller 60. The volume controller 60 is connected to the volume selector switch 12, and the volume can be controlled by operating the switch.

A power supply circuit 64 (when the power switch 2 is turned on, the battery 1
9 or power supplied from the AC adapter 17) is supplied via the inverter circuit 63. The brightness of the fluorescent screen 26 can be switched between two levels (for example, a brightness suitable for a bright room and a brightness suitable for a dark room) via the inverter circuit 63 by switching the changeover switch 11. In addition, by controlling the brightness adjustment switch 3, the brightness of the LCD 22 can be controlled to a desired value in multiple steps. The switch 65a is turned on / off according to whether the battery 19 mounted on the main body 1 is a primary battery or a secondary battery. The switch 65b detects the capacity of the battery 19, and is turned on / off according to the size of the capacity. These switches 65 a and 65 b are connected to the key interface 62 via the power supply circuit 64. The key interface 62 is also connected to the brightness adjustment switch 3, the changeover switch 11, the stop switch 13, and the like. The key interface 62 supplies signals corresponding to ON / OFF of these switches to the CPU 41.

An IC card 70 is connected to the socket 14, and the CPU 41 can exchange data, programs, and the like with the IC card 70 via an IC card interface 66. In addition, sockets 15, 1
The adapter 6 is connected to the CPU 6 via the extension interface 68.

Next, the operation of the time display will be described with reference to the flowchart of FIG.

First, in step S1, the CPU 41
Monitors the output of the timer IC 55 and checks the current time. This current time is stored in the built-in memory R (S
2). Next, the CPU 41 checks the current time pattern from the table stored in the RAM 52 in advance (S
3). That is, as shown in FIG.
A pattern is stored in which 24 hours of the day are divided into three or more (four in the present embodiment) periods.

In the case of this embodiment, 24 hours is 0:00.
The first period T1 from 11:00 to 11:59 and 12:00
A second period T2 from 0 to 12:59, a third period T3 from 13:00 to 19:59, and 20
It is divided into a fourth period T4 from 0:00 to 23:59. The first to fourth periods correspond to the additional characters “morning”, “daytime”, “afternoon”, or “night”. Other characters that can be intuitively recognized, such as "early morning" and "midnight", can be used as the additional characters. Although the number of characters is not limited, it is desirable that the number of characters be three or less, preferably two, in consideration of commonly used "am", "pm" and the like.

When it is determined which of the four periods the current time belongs to, an additional character corresponding to that period is displayed, and the additional character is stored in the memory P (S
4). Then, the current time is displayed by a 12-hour number (time display section) indicating the current time and its additional characters (period display section) (S5). Further, the current time is checked (S6), and it is determined whether the current time is equal to the value stored in the memory R (S7). When the current time is different from the time stored in the memory R, the new current time is stored in the memory R (S8). Then, the pattern at the current time is checked again (S9), and it is determined whether or not the pattern (period) is equal to the value stored in the memory P (S10). If the pattern of the current time is equal to the value stored in the memory P, only the numeral indicating the time is changed to a new one, and the time is displayed by the numeral and additional characters (S12). On the other hand, if the pattern at the current time is different from the value stored in the memory P, an additional character corresponding to the new pattern is displayed, and the pattern is registered in the memory P (S11). Then, the time is displayed by the updated additional characters and numbers.

The above processing is repeated to display the time.

FIG. 8 shows a state in which the time is displayed on the screen 8. This display example shows a case where a meeting schedule is input to the electronic organizer. In order to input this schedule, a type plate 82 as a window is displayed on the page plate 81. In this type plate 82, the date and time indicated in the Christian era indicating the start date and time of the conference, and the time indicating the end time of the conference can be input. According to each date and time,
Up button 8 to increase or decrease those display values
3u to 89u and down buttons 83d to 89d are displayed.

For example, when the up button 83u is touched with the pen 6, the number indicating the year is 1991, 1992, 19
.. Are incremented one by one, and when the down button 83d is touched, 1991, 1990,
1989,... Are sequentially decremented by one. When the up button 86u or 88u corresponding to the time is touched, the time advances by one hour and the down button 8
Touching 6d or 88d will delay the time by one hour. Then, for example, in the state where “until 12:15 in the day” is displayed, if the time is delayed by one hour by touching the down button 88d,
Since the pattern changes from T2 to T1, the display is "11 am
Until 15 minutes ".

After the predetermined date and time are set on the type plate 82 as described above, when the write button 90 is touched with the pen 6, the date and time input on the type plate 82 is written on the page plate 81.

In the above, the case where the time is digitally represented by a number has been described. However, the present invention can be applied to a case where the hour hand and the minute hand are represented in an analog manner.
