    [22] 1 is a block diagram illustrating an output device of a mobile communication terminal according to a preferred embodiment of the present invention.
    [23] As shown, the mobile communication terminal 10 transmits / receives data such as E-mail from another mobile communication terminal 30 through the mobile communication network 300 and provides various contents provided through the wireless web server 50. To be provided.
    [24] In order to output the various data provided through the mobile communication terminal 10, first, an output data transmission unit 100 is installed in the mobile communication terminal 10, and a transmission data output unit may be provided in the printer 20 that outputs data. 200) is installed.
    [25] The output data transmission unit 100 compresses the data to be output from the mobile communication terminal 10 into a file such as JPEG and transmits the data to the transmission data output unit 200 of the printer 20 through a USB cable, and transmits the transmission data output unit. The decompression unit 200 decompresses the transmitted data and generates printing data to perform output.
    [26] On the other hand, the output device of the mobile communication terminal 10 comprising the output data transmission unit 100 and the transmission data output unit 200 is installed in any of the mobile communication terminals (10, 30) to the type of printer 20, 40 Of course, output is possible.
    [27] 2 is a block diagram illustrating in detail an output data transmission unit and a transmission data output unit of an output device of a mobile communication terminal according to an exemplary embodiment of the present invention.
    [28] The output data transmission unit 100 is installed in the mobile communication terminal 10 to output data of the mobile communication terminal 10. The configuration thereof will be described with reference to FIG. 2.
    [29] The JPEG encoder 102 converts the selection data into compressed data such as JPEG format data to the mobile communication terminal 10 to be output through the printer 20.
    [30] The USB control unit 103 converts the data compressed through the JPEG encoder 102 into data suitable for USB.
    [31] USB (Universal Serial Bus) is a type of serial port that has attracted interest with the release of Windows 98. It is a plug-and-play interface between computers and peripherals such as audio players, joysticks, keyboards, scanners, phones and printers.
    [32] It's the same as a serial port, but it's faster and easier to connect than a serial port. It supports data transfer rates of 12 Mbps, so it's fast enough to connect any kind of peripherals, and you can chain up to 127 devices. have.
    [33] The USB control unit 103 performs a role of converting data to enable such a USB connection with the printer 20 through the USB cable 400.
    [34] The USB port 104 provides a port that can be combined with the USB cable 400.
    [35] The transmission controller 101 controls the operation and data flow of the units 102 to 104 belonging to the output data transmitter 100.
    [36] On the other hand, the transmission data output unit 200 installed in the printer 20 is configured around the output control unit 201 that controls the operation and data flow of the configuration units 202-206 in the transmission data output unit.
    [37] The printer USB port 202 receives the output data of the mobile communication terminal 10 transmitted from the USB port 104 via the USB cable 400.
    [38] The printer USB control unit 204 converts the transmitted output data into JPEG data and stores it in the memory 205 of the printer.
    [39] The JPEG DECODER 203 decodes and decompresses JPEG data stored in the memory 205 by the printer USB control unit 204.
    [40] The printing data generator 206 generates a print file of decoded output data.
    [41] 3 is a flowchart illustrating an operation of an output device of a mobile communication terminal according to an exemplary embodiment of the present invention.
    [42] Hereinafter, a series of operations of transmitting output data from the mobile communication terminal 10 to the printer 20 and outputting the data for outputting the data will be described with reference to FIGS. 2 and 3.
    [43] When the mobile communication terminal 10 wants to output (print) a file or a message, an E-mail, a video or an image file, and selects data for output and transmits it to the printer, the JPEG is first considered in consideration of its capacity. ENCODER 102 should perform compression in JPEG (step: S1).
    [44] Subsequently, in order to transmit the compressed file to the printer 20 through the USB channel, the USB control unit 103 converts the JPEG file into data transferable to USB (step: S2).
    [45] In this case, the JPEG ENCODER 102 and the USB controller 103 which perform compression may be implemented using a separate hardware chip or software.
    [46] Data converted by the USB control unit 103 is transmitted to the USB port 104 and transmitted to the printer 20 via the USB cable 400 (step: S3).
    [47] On the other hand, the printer USB port 202 of the transmission data output unit 200 of the printer 20 receives the transmitted data (step: S4) and the printer USB control unit 204 is a memory of the printer in the form of a JPEG file ( 205) (step S5).
    [48] At this time, the printer 20 should check whether the received data is a PC printing file or a JPEG file in order to print the data received through the USB channel, which can be checked when checking the USB protocol and is a PC printing file. In this case, it is preferable to print through the conventional file processing.
    [49] Subsequently, in order to output the compressed data, a restoration operation thereof must be performed, and the JPEG DECODER 203 decodes and decompresses the compressed file stored in the memory 205 (step: S6).
    [50] The decompressed and restored output data is generated as CMYK data for printing through the printing data generator 206 (step S7), and the printer 20 outputs the generated CMYK data (step S8).
    [51] Preferably, the printer USB control unit 204, the JPEG DECODER 203 and the printing data generator 206 may be implemented as a separate hardware chip or software.
    [52] In addition, the aforementioned mobile communication terminal 10 means a cellular phone, a PCS, a PDA and an IMT-2000.
    [53] Although the preferred embodiments of the present invention have been described in detail above, those skilled in the art will appreciate that the present invention may be modified without departing from the spirit and scope of the invention as defined in the appended claims. It will be appreciated that modifications or variations may be made. Therefore, changes in the future embodiments of the present invention will not be able to escape the technology of the present invention.
    [54] As described above, according to the present invention, when outputting data of a mobile communication terminal, output is possible through a direct interface with a printer without using an intermediate medium such as a PC, and the driver moves as the mobile communication terminal moves. It is possible to solve the problem of re-installing the driver of the communication terminal and the printer through a PC. As a result, various data such as E-mail messages and Internet contents serviced in the mobile communication terminal as well as various data serviced through IMT-2000, etc. It is a useful invention that has the advantage of being able to easily perform the output for these through the printer.
