Reference numeral 8 denotes a backup battery built in the apparatus main body, which supplies power to the real-time clock 1. Reference numeral 9 denotes a power supply system control unit for selecting the battery pack 7 or the backup battery 8 as a power supply of the device main body.

The real-time clock 1 and the counter unit 2 constitute a clock unit and a clock unit. The control unit 3 constitutes a calculating unit, an operation detecting unit, a power supply detecting unit, and a subtracting unit. The notification unit is configured by the unit 7.

The operation of initializing the current time in the portable electronic device configured as described above will be described.

After setting the function mode to the current time setting mode by operating the key input unit 4, the user recognizes the correct time by a time signal from a telephone service or the like, and inputs the time by the key input unit 4. The controller unit 3 notifies the user notification unit 6 of the time input by the key input unit 4 as the current time, and starts at midnight based on the time input by the key input unit 4 (separation). Then, the converted count value is sent to the counter unit 2.

The counter 2 counts up the count value sent from the controller 3 based on the reference clock generated by the real-time clock 1 to count the current time, and counts the counted value. Send it to unit 3.

The controller unit 3 converts the count value sent from the counter unit 2 into a time, and notifies the user of the converted time as the current time by the user notifying unit 6, thereby measuring the current time in the clock function. Is performed, so that the user can easily recognize the current time.

Next, the operation of the designated time notification function will be described.

In the state where the current time is measured in the clock function by the above operation control, when the setting instruction of the designated time notifying function is performed by the key input unit 4 (step F1), the notification request time input mode is entered. In this input mode, when the user inputs a time at which a notification is requested by the key input unit 4 and selects a function to be operated at the notification request time (step F2), the controller unit 3 controls the user notification unit 6. In addition to notifying the time input by the key input unit 4 as the notification request time and notifying the function that operates at the notification request time, the controller unit 3 notifies the nonvolatile memory 5 of the notification input by the key input unit 4. The request time and the selected function operation are written (step F3).

If the user does not instruct the designated time notification function in the state where the notification request time is set (step F4), the controller unit 3 sets the count start bit in each control register and in the nonvolatile memory 5. In the state where the notification request time has been set, the user instructs the designated time notification function to operate (step F4). The unit 3 writes “1” indicating the operation instruction of the designated time notification function in each control register and the count start bit of the nonvolatile memory 5 (step F).
At the same time as 6), the notification request time written in the nonvolatile memory 5 is read, and the time difference between the read notification request time and the current time measured by the counter unit 2 is set as a value with 1 second as a minimum unit. Calculate (Step F
7).

As a method of obtaining the time difference, for example, the current time and the notification request time are set to 0 am in the 24-hour method.
The time is converted into a count value that is counted in units of 1 second using the time as a reference (delimiter), the count value of the current time is subtracted from the count value of the notification request time, and when the difference is plus (positive), the value is When the time difference data is obtained and the difference is negative (negative), the value is set to 2 in the 24-hour method.
The value obtained by adding “86400” which is the count value at 4:00 is the time difference data.

The time difference data calculated by the controller unit 3 is sent to the counter unit 2, and the counter unit 2 writes data "1" which is written in the count start bit in the control register and indicates the start of operation of the designated time notification function. ", The counting using the reference clock generated by the real clock time 1 is started (step F8).

When the count value counted by the counter unit 2 matches the time difference data (step F10), an interrupt is issued to the controller unit 3, and the controller unit 3 notifies the controller of the cause of the interrupt by the designated time notification. It recognizes that there is, and reads out the functional operation to be performed at the designated request time from the non-volatile memory 5 to perform the functional operation (step F11).

On the other hand, in a state where the counter unit 2 is counting the set time difference using the reference clock generated by the real clock time 1 (step F8), the battery pack 7 provided separately from the main body of the device is not counted. When the power supply to the device main body is cut off due to insufficient capacity or the battery pack 7 is removed from the device main body (step F9), the power supply system controller 9 switches the power supply of the real-time clock 1 to the backup battery 8. The generation of the reference clock by the real-time clock 1 is continued by the backup battery 8, so that the counting of the current time by the counter unit 2 is continued.

Then, in a state where the current time is being measured by the power supply from the backup battery 8, the shortage of the capacity of the battery pack 7 is eliminated or a new battery pack 7 is mounted (step F12). After a series of initial settings are performed in the controller unit 3, it is determined that the clocking of the current time is continued (step F13). In response to the determination result, a count start bit is read from the nonvolatile memory 5,
If the data stored in the count start bit read from the non-volatile memory 5 is data “0” indicating the non-operation of the designated time notification function (step F16), this operation is terminated, and When the data stored in the read count start bit is data “1” indicating the start of operation of the designated time notification function (step F1)
6), the notification request time is read from the nonvolatile memory 5,
The read notification request time is compared with the current time measured by the counter unit 2 (step F1).
7).

When the power supply to the real-time clock 1 is cut off due to the shortage of the capacity of the clock backup battery 8 and the clocking of the current time is not continued, the shortage of the capacity of the battery pack 7 is solved again or a new battery is used. When the pack 7 is mounted (step F12), after a series of initial settings are performed in the controller unit 3, it is determined that the time measurement of the current time is not continued (step F13), and in response to the determination result, The mode shifts to the current time setting mode, and when the user inputs the current time in this setting mode (step F1).
4, step F15), the data stored in the count start bit is read out from the non-volatile memory 5 and a judgment operation is performed (step F16). Based on the judgment result, the notification request time is read out from the non-volatile memory 5 and read out. The notification request time and the current time measured by the counter unit 2 are compared (step F17).

If it is determined in the comparison that the current time has not passed the notification request time (step F).
18) That is, the current time and the notification request time are converted into a count value counted in units of 1 second with respect to midnight in the 24-hour system as a reference (delimiter), and the count value of the notification request time is used as the count value of the current time. When the value obtained by subtracting is plus (positive), the user notifying unit 6 notifies the subtracted value to the outside as a time until the setting operation is performed (step F19), and the controller unit 3 stores the value in each control register. Write "1" indicating the operation instruction of the designated time notification function in the count start bit of (step F20),
The count value obtained by subtracting the count value of the current time from the count value of the notification request time is sent to the counter unit 2 as time difference data, and the counter unit 2 executes the designated time notification function written in the count start bit in the control register. In response to the data "1" indicating the start of operation, counting using the reference clock generated by the real clock time 1 is started (step F8).

When the count value counted by the counter unit 2 and the time difference data match (step F10), an interrupt is generated for the controller unit 3, and the controller unit 3 determines that the cause of the interrupt is a specified time notification. It recognizes that there is, and reads out the functional operation to be performed at the designated request time from the nonvolatile memory 5 and causes the functional operation to be performed (step F11).

Therefore, according to the above-described operation control, when the power supply is cut off after the designated time notification function is operated and the power supply is restarted thereafter, the user performs a reset operation of the notification request time. Thus, the designated time notification function based on the notification request time set before the power supply is cut off can be operated.

Also, when comparing the notification request time read from the nonvolatile memory 5 with the current time measured by the counter unit 2 (step F17), it is determined that the current time has passed the notification request time. (Step F
18) That is, the current time and the notification request time are converted into a count value counted in units of 1 second with respect to midnight in the 24-hour system as a reference (delimiter), and the count value of the notification request time is converted to the count value of the current time When the value obtained by subtracting is minus (negative), the time after the notification request time is obtained by converting the value to a time in the 24-hour method (step F21). Notify outside (step F22).

Therefore, according to the above operation control, when the user reattaches the battery pack 7 after the time at which the notification is requested in advance, it is possible to easily recognize the time elapsed from the notification request time. it can.

In the above embodiment, the present time measured as the clock function is set to one day based on the 24-hour clock. However, the present invention is not limited to this.
It may be in weekly units based on the time method.

[0038]

As described above, according to the first and second aspects of the present invention, the power supply is cut off after the set time notification function is operated, and then the power supply is restarted. When resetting is performed, the setting time notification function is operated without complicated operation by the user by resetting the setting time notification based on the notification request time stored in the nonvolatile memory. It is possible to prevent the setting from being forgotten due to the attachment / detachment of the battery.

According to the third aspect of the invention, when the notification of the set time is reset, the time until the notification request time is reached is notified, so that the user needs to notify the set time. Confirmation can be made, and unnecessary notification can be prevented based on the confirmation result.

According to the fourth aspect of the invention, when the set time notification is reset, and the current time at that time has passed the notification request time, the user is notified by notifying the time. , It is possible to easily recognize how many hours have passed since the requested time, and accordingly, the user can take quick action.
