Next, the power-off processing procedure in the power-off processing unit 55 will be described in detail with reference to the flowchart of FIG.

When the power-off processing unit 55 is activated, whether or not there is a document to be saved, whether the memory backed up by the battery during power-off, or the editing state of the document in the non-volatile memory 2 (42) is checked. Check (10
1) If there is no document to be saved, transition to (120),
Turn off the power.

As a result of the check in (101), if there is a document to be saved, the document data is compressed (10
2). The document data compressing means may be only a padding unused area of the document data, or may be a compressing means such as MH compression realized by image data processing or the like.

After (102), the compressed document data is saved in the memory which is backed up by the battery while the power is off or the document data area (3-2) in the non-volatile memory 2 (42) (103). ). (10
After 3), the document data area (3

It is checked whether it has been saved in (104). Memory 2
If all the document data can be saved in the document data area (3-2) in (42), the process proceeds to (120) and the power is cut off.

As a result of the check in (104), all the document data are stored in the document data area (3-) in the memory 2 (42).
If the data cannot be saved in 2), the document data that could not be saved in the document data area (3-2) in the memory 2 (42) is saved in the floppy disk. 3 is checked (105), and if the floppy capable of saving the document data is not set in the external storage device 3, a floppy set message is displayed (106). (10
After 6), key input with a timer designation is performed (in the present embodiment, the monitoring timer value of the non-input time is 5 minutes) (10
7). When a key input with a timer designation is requested, the input control unit designates the monitoring time as 5 minutes and activates the time monitoring unit 56. If a key is input before the time monitoring unit 56 notifies that the designated time has elapsed, the input control unit requests the time monitoring unit 56 to stop the monitoring timer and returns the input key. When the designated time has passed, the time monitoring unit 56
The input control unit is notified that the designated time has elapsed. When the input control unit is notified from the time monitoring unit 56 that the designated time has elapsed, the input control unit returns “tomout” as no input.

It is checked whether or not the key input in (107) is the <execution> key (108). If the key is the <execution> key, the process proceeds to (105). As a result of the check in (108), if it is not the <execution> key, it is checked whether the input key is the <end> key (109), and if it is the <end> key, the process proceeds to (120) and the power is turned off. ..

As a result of checking (109), if the key is not the <end> key, it is checked whether the input key is "timeout" (no input for 5 minutes) (110), and if the input key is timed out (120). Transition to and turn off the power. If the result of checking (110) is that the input key is not a timeout, a buzzer sound is output (111),
It branches to (107).

As a result of the check in (105), if the floppy capable of saving the document data is set in the external storage device 3, the document data is backed up to the floppy (1
12). After (112), it is checked whether the backup processing to the floppy has been normally completed (113). If the backup processing to the floppy has been normally completed,
Transition to (120) and power off. If the result of the check in (113) is that the backup processing to the floppy disk has terminated abnormally, an error message indicating the abnormal termination is displayed (114). After (114), key input with a timer designation is performed (in this embodiment, the monitoring timer value of the non-input time is 5 minutes) (115). It is checked whether the key entered in (115) is the <execute> key (116), <
In the case of the execution> key, the process transits to (112). (116)
If it is not the <execution> key, it is checked whether the input key is the <end> key (117), and if it is the <end> key, the process proceeds to (120) and the power is turned off. If the result of the check in (117) is not the <End> key, the input key is "timeout" (no input for 5 minutes).
It is checked (118) whether the input key has timed out, and the process proceeds to (120) to turn off the power.
If the result of the check in (118) is that the input key is other than timeout, a buzzer sound is output (119), (11
Branch to 2).

In this embodiment, by pressing the cancel key while the floppy set message is being displayed or the error message due to the floppy backup error is being displayed,
You may return to the state before pressing the power switch.

Further, in this embodiment, the monitoring timer for the non-input time is designated for the key input, but the monitoring timer for monitoring the input interval may not be designated in order to prevent the document data from being discarded.

[0034]

As described above, according to the present invention,
It has the following effects.

(1) Even if the editable document data increases,
After compressing the document data, you can save all the document data to the battery-backed memory or non-volatile memory while the power is off, and to the battery-backed memory or non-volatile memory when the power is off. If not, by saving the document data in the external storage device, it is possible to minimize the memory backed up by the battery while the power is off or the non-volatile memory.

(2) If the battery is backed up while the power is off, or if all the document data cannot be saved in the non-volatile memory, the document data can be saved in the external storage device only once. Furthermore, if all the compressed document data can be saved in a battery-backed memory or a non-volatile memory by a battery during power-off, no user operation is required, and operability is improved.

(3) When a document is being edited with only the battery and the power switch is pressed to save the document data to an external storage device such as a floppy disk, a response from the user is required and for a certain period of time. When there is no response from the user, the power consumption can be reduced by forcibly turning off the power.
