Hereinafter, a portable telephone provided with a data backup unit of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block circuit diagram of a mobile phone 1 equipped with a data backup unit 30 of the present invention. First, the operation state of the general mobile phone 1 will be described.

In the conventional mobile phone 1, the main controller 10 is used to control the overall control of the mobile phone, and controls the operation state of the mobile phone 1 by using the data stored in the ROM / RAM memory unit 26. . In the ROM / RAM memory unit 26, a ROM includes a basic program necessary for operating a mobile phone, and a RAM stores a temporary data generated during a mobile phone operation. In addition, a non-volatile memory device such as a flash ROM is used in a ROM to semi-permanently store data stored by a user such as a telephone number.

In addition, the display unit 12 is for displaying data necessary for the operation of the mobile phone, and a liquid crystal display (LCD) is mainly used. In addition, the key input unit 22 is for generating key data for performing various function setting and dialing of the mobile phone and inputting the key data into the main controller 10. Using the key data input from the key input unit 22 to make a call or perform a function embedded in the mobile phone.

In addition, the A / D converter 14 converts an analog signal into a digital signal, and the D / A converter 16 performs a function of converting a digital signal into an analog signal. The voice or text data signal converted by the A / D converter 14 is frequency-modulated by the radio transmitter / receiver 18 and then propagated as a radio signal through the antenna 20. On the other hand, after the wireless signal input through the antenna 20 is received through the wireless transmission and reception unit 18, the digital signal contained therein is modulated into an analog signal and input to the main controller 10.

The battery 24 supplies power necessary for the operation of the mobile phone, and the wireless transmitter / receiver 18 performs a function of transmitting and receiving a radio signal through the antenna 20. The battery 24 includes an IF module and an RF module. It performs the function of demodulating.

In addition, the codec 28 modulates the analog voice signal input by the user into a digital voice signal, and modulates the digital voice signal into an analog voice signal and outputs the analog voice signal. On the other hand, text data other than voice data is processed by the main control unit 10 and is output so that the display unit 12 can visually recognize.

According to the present invention, the data backup unit 30 is further included in the conventional mobile phone 1 having the above configuration. The data backup unit 10 is for backing up semi-permanently stored data such as a phone number and an address stored in the ROM / RAM memory unit 26. In other words, the data backup unit 30 backs up data such as a phone number and address having the same contents as the contents stored in the ROM / RAM memory unit 26, so that the mobile phone cannot be used due to loss or damage. In this case, data can be effectively recovered.

The data backup unit 30 has a built-in flash memory device that can easily read / write and store data semi-permanently as a memory device for storing data. It is preferable to write or read data in the data backup unit 30 in the same manner as the conventional ROM / RAM memory unit 26.

In particular, in the present invention, by detachably configuring the data backup unit 30, it is preferable to separate the data backup unit 30 from the mobile phone 1. This is because when the data is stored in the mobile phone 1 when lost or damaged, the effect of data backup is halved or not at all. Therefore, after performing the data backup every time or storing new data, the data backup unit 30 is separated. will be.

Data recovery is performed by attaching the data backup unit 30 to a new mobile phone 1 having no data stored therein, and then recovering the data from the data backup unit 30 to the ROM / RAM memory unit 26 of the mobile phone 1. This can be done by entering a command to transmit for. By the data transfer command, the main controller 30 reads the data stored in the data backup unit 30 and stores the data in the ROM / RAM memory unit 26. In this way, a new mobile phone can be used as usual.

3 shows the installation position of the data backup unit 30 according to the present invention. As shown, the data backup unit 30 is inserted on the inner surface of the portion where the battery 24 is mounted. The data backup part 30 has fastening portions 304 formed on both sides thereof, and is fixed so as not to be separated during insertion. The data backup unit 30 has a memory device built therein and stores data input through a connection terminal (not shown). The internal memory device is a nonvolatile memory device and the stored data is not erased even when the power supply is cut off. Therefore, even after the data stored in the ROM / RAM memory unit 26 is copied, the data backup unit 30 is separated from the mobile phone 1 to retain the data. The copying procedure for backing up the data will be described later.

4 is an external perspective view of the data backup unit 30 in a state of being separated from the mobile phone 1. As shown in the figure, a fastening portion 304 is formed on each of the upper sides. In addition, a plurality of connection terminals 302 are formed at one lower side. The connection terminals 302 are for data transmission and reception with the main control unit 10. Referring to FIG. 1, the main control unit 10 is connected to the ROM / RAM memory unit 26 and the data backup unit 30, and copies the stored contents back to the data backup unit 30 after storing the text data. , Save.

FIG. 5 shows an accommodating part 32 formed on the rear surface of the mobile phone 1 for accommodating and fixing the data backup part 30. The accommodating part 32 is formed toward the inside of the main body of the mobile phone 1, and has a form that is normally cut off from the outside by the battery 24. Therefore, even when the data backup unit 30 is mounted in the storage unit 32, the outside is not easily separated. In addition, there is an advantage that the data backup unit 30 to be inserted into the accommodating unit 32 can be easily separated after the battery 24 is removed. The accommodating part 32 has a terminal part 322 electrically coupled to the connection terminal 302 of the data backup part 30 on an inner surface thereof, and a fixing part coupled to the fastening part 304 on both upper surfaces thereof. 324 is formed.

The backup processing in the data backup unit of the present invention having the above configuration will be described below with reference to the flowchart of FIG. 2.

Entering text using the mobile phone (1) and pressing the storage function key (the storage function key differs depending on each mobile phone), the main control unit 10 detects this and the data commanded to store the ROM / RAM memory Stored in section 26. Data stored at this time is stored semi-permanently.

After the data is stored in the ROM / RAM memory unit 26 as described above, the main control unit 10 backs up all the data stored in the ROM / RAM memory unit 26 to the data backup unit 30. In other words, after reading data from the ROM / RAM memory unit 26, such as a telephone number and address, from the main control unit 10, the data is recorded again in the data backup unit 30. When the storage of the data is completed, the main controller 10 ends the data backup function.

The data backup function may be selectively executed to be executed only when a specific function command key is input by the user or may be selectively stored so that data is always stored after the specific data is stored. In the former case, the data backup unit 10 may be mounted and executed in the storage unit 32 in a state where the data backup unit 30 is separated from the mobile phone 1. In the latter case, the data may be stored in the main control unit 10. It can be configured to check that the backup unit 30 is mounted and to execute only when it is mounted.

When data backup is completed while the data backup unit 30 is mounted, the user removes the battery from the mobile phone 1 and presses the fastening unit 304 of the data backup unit 30 to receive the storage unit 32. The data backup unit 30 is separated from the data backup unit 30. The separated data backup unit 30 can store data by storing it in a safe place.

In the above description of the present invention, it is described that the data is automatically backed up when the operating state of the mobile phone is sensed. However, it is obvious that the user can actively back up the data. In other words, if the data backup function is set to a specific function key, and the function key is pressed while the data backup unit 30 is mounted in the storage unit 32, all data stored in the ROM / RAM memory unit 26 is stored. Copied to the backup unit 30 performs a backup function.

According to the present invention, it is possible to safely store the data stored in the mobile phone, it is easy to recover the stored data even if the mobile phone is damaged, and by attaching a removable data backup unit easily mounted on a new mobile phone even if the mobile phone is damaged or lost By doing so, it is easy to recover data.
