DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing apparatus, and more particularly to a data processing apparatus driven by a battery and having a data backup function.

[0002]

2. Description of the Related Art In recent years, data processing devices such as personal computers, word processors, and PDAs have been developed.
Devices having a function of backing up data during processing are widely used. This backup function is a kind of insurance copy that is created as a backup in case a file in use is damaged or destroyed by a duplicate copy of a program, disk, or data. Also, some application programs automatically create backup copies of data files and save both the current version and the old version on a disk.

In the meantime, among the above data processing apparatuses, a type in which a drive voltage is supplied to each part in the apparatus by an internal power supply such as a battery has been widely used. A method of operating the backup function in conjunction with the consumption of the internal power supply has been proposed. Specifically, for example, in a data processing device such as a personal computer or a word processor driven by a battery, when the consumption of the battery is detected, a message prompting a backup of data or the like is displayed. , An instruction to execute backup of data, etc., and in accordance with the instruction, the data is backed up to an external storage device or the like.

[0004]

However, in the conventional data processing apparatus, when backup of data is performed when the battery is exhausted, a driving voltage is supplied from the battery to other units in the apparatus. For this reason, there is a problem that the life of the battery during the backup is expired and an appropriate backup may not be performed.

[0005] It is an object of the present invention to provide a data processing device capable of properly backing up data even when a battery is exhausted.

[0006]

According to the first aspect of the present invention,
A data processing device driven by being supplied with power to each unit by a battery, wherein the remaining power of the battery is small by the remaining power detection means for detecting the remaining capacity of the battery and the remaining power detection means. When it is determined that there is, backup request means for instructing backup of the data being processed, and when a backup instruction is issued by the backup request means, power of unnecessary units in the data processing apparatus is turned off. Power-off means, and backup means for storing the data being processed as backup data in storage means after power-off of unnecessary parts in the data processing device is turned off by the power-off means. This solves the above problem.

According to the first aspect of the present invention, in the data processing device driven by a battery, the remaining power detecting means detects the remaining power of the battery, and the backup requesting means detects the remaining power. Means for instructing a backup of the data being processed when the battery level is determined to be low, and a power-off means for providing a data processing device when the backup request is issued by the backup requesting means. The power of the unnecessary parts in the data processing device is turned off, and the backup means turns off the power of the unnecessary parts in the data processing device by the power cutoff means. Remember.

Therefore, according to the first aspect of the present invention, when backing up data being processed when power is consumed, unnecessary units in the apparatus are turned off and then backed up to the storage means. Therefore, it is possible to appropriately perform data backup at the time of battery exhaustion.

Further, in this case, as in the invention of claim 2,
The backup means is provided when, after the power of the unnecessary parts in the data processing apparatus is turned off by the power supply cutoff means, the power remaining amount detection means detects that the battery remaining amount has recovered to some extent. It is effective to store the data being processed as backup data in the storage means.

Therefore, according to the second aspect of the present invention, when backing up data at the time of power consumption,
Since the configuration is such that data backup is performed when it is detected that the remaining battery level has recovered to some extent after the power supply of unnecessary parts in the apparatus is turned off, the effect of claim 1 is obtained. Data can be backed up accurately.

Further, in this case, as in the invention of claim 3,
The backup unit stores the data being processed as backup data in a storage unit when a predetermined time has elapsed after the power of the unnecessary units in the data processing device has been turned off by the power-off unit. It is effective.

Therefore, according to the third aspect of the present invention, when backing up data at the time of power consumption, when a predetermined time elapses after the power supply of unnecessary parts in the apparatus is turned off, Since the backup is performed, the data can be backed up more accurately in addition to the effect of the first aspect.

In this case, it is effective that one of the power supplies of the unnecessary parts is a power supply for driving a display device.

Therefore, according to the fourth aspect of the present invention, at the time of data backup, the power supply of the display device which is the unit with the largest power consumption in the device is turned off. Thus, data can be backed up more accurately.
