Next, among the control procedures of the CPUs 2 and 48, an example of a control procedure for designating a time and generating an alarm sound will be described with reference to FIGS. 4 to 6. FIG.

FIG. 4 shows a flowchart of an example of an alarm registration procedure. In step S1, the function mode is set by pressing the function key 43a on the operation panel,
In the next step S2, pressing the ▲ [*] ▼ key 52b switches to the alarm registration mode. Then, the process proceeds to step S3, where the first alarm registration is performed, the ▲ [1] ▼ key of the ten keys 52a is pressed to proceed to step S4, and the following display is displayed on the display 42. Then, the process proceeds to Step S5.

Here, the alarm time is input. For example, 22:30
When you want to enter the minute, press the numeric keypad 52a. By pressing the buttons in this order, the following is displayed on the display 42 and the time input is stored in the RAM 4.

Next, the process proceeds to step S6, where the following display is made on the display 42.

Therefore, in step S6, a desired message is input using the numeric keypad 52a as shown in Table 1 below.

That is, ▲ [1] ▼, ▲ [7] ▼ on the numeric keypad 52a.
Use the keys to search for alphabetical (A to Z, a to z,) up / down, ▲ [2] ▼, ▲ [8] ▼ keys to katakana (Ai to Wan, "゜ space.", ヲ, ヲ) Search for up / down of joystick, ▲ [3] ▼, ▲
[9] Use ▼ key for numbers and symbols (01 to 9 :; <=>? Space)
! "# @% &'() * +,-. /) Is determined for up / down search, and a desired character is designated by keeping one of the numeric keys pressed.

For example, if you want to register "Hanbaikigi" as a message, keep pressing the ▲ [2] ▼ or ▲ [8] ▼ key, and the katakana will automatically change and will be displayed. Stop pressing the numeric keys ▲ [2] ▼ and ▲ [8] ▼. The display 42 Is displayed. By repeating the same operation, the display 42 Is displayed, and the message is stored in RAM4.

In the case of the second, third, and fourth alarm registrations, the same processing as in step S3 is sequentially performed, and steps S3 ′, S3 ″, and S3 for determining the second, third, and fourth alarm registrations are sequentially performed. Then, in steps S4 ′, S4 ″, and S4 of the display, the display 42 is displayed. Is displayed, and the time and message are registered in the same manner as in steps S5 and S6 described above.

Then, in step S7, the start key switch 54
By pressing, counting of the alarm time starts.

The stop / clear key switch 53 shown in FIG. 3 is pressed when the key switch is operated incorrectly.
The procedure of FIG. 4 returns to step S1.

When the registration of the alarm message is completed as described above, the CPU 2 enters the standby mode.

In FIG. 4, when the function key 43a is not depressed in the step S1, the step S1 is executed.
The process proceeds to 9, S10, and S11, and in steps S12, S13, and S14, a subroutine for one-touch dialing, speed dialing, and copying is performed.

When the ▲ [#] ▼ key 52c is pressed in step S2, the process proceeds from step S15 to step S16, where the process proceeds to a print subroutine. If it is determined in step S15 that a function key other than the ▲ [*] ▼ and ▲ [#] ▼ keys has been pressed, the flow advances to the function key subroutine in step S17, where the mode for the pressed function key is executed. .

During standby, the sub CPU 45 always compares the time at which the alarm is registered with the time data of the clock IC according to the flowchart shown in FIG.

In step S20, the start key 54 on the operation panel 31
Is detected by pressing (copy, send, etc.), and if not key pressed, steps S21, S22, S2
3. In S24, it is determined whether each alarm registration time has been reached. This is performed by inputting time data from the clock IC 47 to the sub CPU 45 and making a determination by the sub CPU 45.

If the alarm time has been reached in any of steps S21, S22, S23, S24, steps S25, S25 ', S2
5 ", the main CPU 2 is started in S25, and then, in steps S26, S26 ', S26", S26, each command of the alarms 1, 2, 3, and 4 is transmitted from the sub CPU 45 to the control device 16, PPI 8, Send to main CPU2 via bus BUS, sub CPU
45 returns to step S20.

Subsequent processing is based on the control procedure of the main CPU 2 shown in FIG.

In FIG. 6, after the main CPU 2 started the main power supply 27 from the sub CPU 45, the main CPU 2 initializes the I / O electric system in step S40, and then in step S41, the sub CPU
Enter the command from 45. This is the step in Figure 5.
Corresponds to the command in S26.

If the command is an alarm command, step S4
Proceed to 3, drive buzzer 19 with buzzer driver 18,
Notify the user that the alarm time has come. Further, it is determined by a command whether the plurality of alarms registered in the sequential steps S44, S45, S46, S47 are included.
In steps S46, S48 and S49, the alarm message registered in advance according to the type of the alarm is transmitted to the recording paper RP by driving the thermal head TPH by the UPI11.
Record above.

Therefore, the user can know what the alarm sound was for by looking at the printed recording paper RP.

Thereafter, the CPUs 2 and 45 return to the standby state again, and wait until the next alarm time according to the procedure of the flowchart of FIG.

The output of the above-mentioned alarm message is not limited to printing on recording paper, but is displayed on the liquid crystal display 42,
Alternatively, the sound may be output from a speaker.

Further, in FIG. 6, when it is determined in step S42 that the received command is not an alarm command, the process proceeds to step S51.
If it is determined that the command is a one-touch command, the process proceeds to an auto dial subroutine in step S52.

If it is determined in step S51 that the command is not a one-touch command, the process proceeds to step S54. If the command is a function mode key, the process proceeds to a subroutine S53 for executing a corresponding function.

FIG. 7 shows the sequence of the power supply operation of the main power supply 27 and the standby power supply 29. The standby power supply 29 is always in the power supply state, but the main power supply 27 is in the cut-off state during standby including the alarm standby state. Power is supplied only during the registration and alarm execution processing. As a result, power consumption is reduced.

[Effect of the Invention] As described above, according to the present invention, it is possible to shift to the power consumption reduction mode in order to reduce power consumption.
Also. Detects whether it is time to output an alarm message even when the device has shifted to the power saving mode, and switches from the power saving mode to the normal power supply mode and outputs an alarm message such as a schedule at that time. can do. Therefore, the alarm function can be operated efficiently without complicating the power supply configuration of the image communication apparatus having the function of shifting to the power consumption reduction mode.
