Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to data protection for portable information terminal equipment.

[0002]

2. Description of the Related Art In recent years, portable information terminal equipment has been reduced in size and weight. However, since the portable information terminal equipment itself is insufficient in strength and weak in electrostatic resistance, external information such as dropping or static electricity causes There is a fragile surface that breaks. It is clear that the mobile information terminal itself has been completely broken into pieces without any traces, but even if it looks undamaged, the built-in data is destroyed and the function as the mobile information terminal is lost. May not work.

Conventionally, when data contained in a portable information terminal device is broken, the data must be repaired by inputting the data from the beginning or backing up the data using an FD or the like.

[0004] Recently, a portable information terminal such as a portable telephone or a portable personal computer has stored hundreds of data such as a telephone number list and an address book, and the amount of data to be stored is increasing. . If this data is destroyed, the restoration requires a lot of time and trouble, and irreparable data may be lost.

[0005] For those who are not used to personal computers,
In particular, it is difficult to back up data on a storage medium such as an FD or to restore data from the FD.

In many cases, the user forgets to back up to an FD or the like.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and it takes more time to repair accidental data destruction of a portable information terminal than before. It is an object of the present invention to provide a charger having a function capable of reducing trouble.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention backs up data of a portable information terminal device while charging the portable information terminal device, and saves time and labor for backup. The configuration is as follows.

When data in the portable information terminal device is destroyed, not all data can be restored, but the data at the time of previous charging can be restored, so that the time and effort for data restoration can be improved. This is particularly effective for large-volume data, such as an address book and a telephone number list, which have relatively few changes, and for people who are not accustomed to operating electronic devices.

The battery charger with a data backup function of the present invention retains the same data at the time of charging as the data stored in the data storage means built in the portable information terminal device. In the case of breakage, data is transmitted from the data storage means built in the charger to the data storage means built in the portable information terminal device.

Having.

Next, the operation will be described. Portable information terminal equipment 1
When charging the secondary battery 110 of No. 01, the portable information terminal device 101 connects to the charger with data backup function 104 by the data connection means 103, the power line connection means 113, and the control signal connection means 117.

The charging of the secondary battery 110 of the portable information terminal device 101 from the charger 104 with the data backup function of the present invention is performed from the charging circuit 115 of the charger 104 with the data backup function to the power output means 114 and the power line connection means 113. The connection is made by connecting the portable information terminal device 101 to the power input means 112 and the secondary battery 110.

In a normal case, data is backed up from the portable information terminal device 101 by the data input / output direction control means 105 in order to back up the data of the portable information terminal device 101 to the charger with the backup function. It is set so as to be transmitted to 104.
That is, the data input / output direction setting means 119 is set to read from the data storage means 102, and the data input / output direction setting means 120 is set to write to the data storage means 107.

When the power line connection detecting means 111 detects that the portable information terminal device 101 has been connected to the charger 104 with a data backup function, the data connecting means 108 passes through the data connecting means 108 from the data storage means 102. Data transmission means 106, data storage means 1
07 is transmitted.

If the data in the data storage means of the portable information terminal device 101 is to be destroyed and it is desired to restore the data, that is, the data whose data has been backed up in the charger with the backup function as described above is transferred to the portable information terminal device 101. In this case, the setting is changed by the data input / output direction control means 105 so that the data is transmitted from the charger 104 with the data backup function to the portable information terminal device 101. That is, the data input / output direction setting means 120 is set to read from the data storage means 107, and the data input / output direction setting means 119 is set to write to the data storage means 102. When the power line connection detection unit 111 detects that the portable information terminal device 101 has been connected to the charger 104 with a data backup function, the data storage unit 107 transmits the data to the data transmission unit 106 and the data connection unit 1.
09, the data connection means 108, the data storage means 1
02, and the data restoration is completed.

With the above-described configuration, when charging, data is always transmitted from the portable information terminal device 101 to the charger 104, and the contents of the data storage means 107 are rewritten to the same as those of the data storage means 102. The same data is retained, and both data can be matched.

On the other hand, when the data contained in the portable information terminal device 101 is destroyed for some reason, the data transmission direction is changed by the data input / output direction control means 105 to the charger 1.
04 to the portable information terminal device 101.

By providing a mode for not transmitting data to the data input / output direction control means 105,
It is also easy for those skilled in the art to stop data transmission from the portable information terminal device 101 to the charger 104 when unnecessary.

In the first embodiment, the data connection means 103, the power line connection means 113, and the control signal connection means 11
Although an example of realizing 7 with a cable has been described, the present invention is not limited to this. The data connection means 103, the power supply line connection means 113 and the control signal connection means 117 are omitted, and the data connection means 108 and 109, the power supply input means 11
2, power supply output means 114, and control signal connection means 1
It is obvious to those skilled in the art that the same effect can be obtained by directly connecting 16 and 118.

[0025]

As described in detail above, according to the present invention,
When the portable information terminal device is normal, by setting the data transmission direction to the charger with data backup from the portable information terminal device, when charging, the data in the data storage means built in the charger is always updated, The built-in data of both can be matched.

When the built-in data of the portable information terminal device is destroyed for some reason, the data stored in the data storage means of the charger with the data backup function is transmitted to the portable information terminal device so that the data is transmitted. It is easy to restore to the data at the charging time that is the shortest from the time of destruction.
