BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for managing image data in an image mail system, and more particularly, to a method of storing and reading image data input from a facsimile apparatus in close contact with a national exchange.

Conventionally, when the facsimile apparatus is set to the automatic reception mode, the ringer sounds a certain number of times, and then proceeds with the protocol according to the I.T.U recommendation to receive the image data received in the reception mode. Also, in the manual mode, after confirming that there is image data to be received after talking with the other party, the image data was received by inputting a start key.

In addition, when the facsimile apparatus receives the image data, the receiver unconditionally receives the image data transmitted by the other party, and cannot determine who is the sender and how much of the image data is received.

As a result, all image data received by the facsimile apparatus is output, which causes a waste of recording paper and a problem of not receiving image data that must be received in a busy state.

Accordingly, an object of the present invention is to store image data received in a HDD (Hard Disk Driver) of an image mail system closely coupled with a local exchange when the facsimile apparatus is busy and provide a fax message.

It is still another object of the present invention to provide a fax message and store it in a HDD (Hard Disk Driver) of an image mail system in close contact with a local exchange when the facsimile apparatus is set to the selective reception mode.

Still another object of the present invention is to provide a method of reading and outputting selected image data when a request for image data transmission is made from a facsimile apparatus.

It is still another object of the present invention to provide a method for deleting selected image data upon request for deleting image data from a facsimile apparatus.

Therefore, an embodiment of the present invention will be described in detail with reference to FIGS. 1, 2, 3, and 4.

First, the process of storing the image data in the image mail system with reference to FIGS. 1 and 2 and 4 will be described in detail. In the standby state, the CPU 110 has received image data to be stored from the local exchange in step 212. Detects whether or not the storage request data indicating that the line interface unit 112 is detected. When the storage request data is detected by the line interface unit 112, the CPU 110 controls the line interface unit 112 to form a storage loop in step 214. When the storage loop is formed, the CPU 110 detects whether image data is input from the local exchange through the line interface unit 112 in step 216. If the image data is input, the CPU 110 detects the HDD 118 in step 218. By controlling, the input image data is stored in the hard disk corresponding to the data number for managing the image data in the form of FIG. 4C. Further, according to the stored image data, the fax message is registered in the format of FIG. 4B. The same format as that of FIGS. 4B and 4C is provided corresponding to one subscriber number provided in FIG. 4A. When the storing of the image data ends, the CPU 110 blocks the storage loop in step 220, and detects whether the corresponding facsimile device is busy in step 222. If the facsimile device is not busy, the call data for calling the facsimile device is controlled by the CPU 110 and output from the line interface unit 112 to the local exchange in step 224. In step 226, the CPU 110 determines whether a transmission loop is formed corresponding to the call data. In addition, when the transmission loop is formed to the corresponding facsimile apparatus, the CPU 110 reads a fax message including the components shown in FIG. 4B from the HDD 118 to the local exchange in step 228. In step 230, it is determined whether the transmission of the fax message has been completed. When the transmission of the fax message is finished, in step 232, the transmission loop formed in step 226 is blocked and the image data storing process ends.

Referring to FIG. 1 and FIG. 3 and FIG. 4, the process of providing the image data stored in the image mail system will be described in detail. In this case, the CPU 110 receives the subscriber number from the facsimile apparatus that receives the fax message in step 310 of FIG. Is inputted to the line interface unit 112, and if the subscriber number is input, the CPU 110 controls the DSP 120 to read a guide message for inputting a password in step 312 to read the line interface unit ( 118) to the national exchange. In addition, when the password corresponding to the password input guide message is input in step 314, the CPU 110 determines whether the correct password is input by comparing the subscriber number shown in FIG. If the input password is incorrect, the CPU 110 controls the DSP 120 in step 338 so that the password is input incorrectly, and reads a guide message to re-enter the password through the line interface unit 118. It is sent to the side. The CPU 110 compares whether the value of the counter has been set in step 340. If the counter value is less than or equal to the set value, the CPU 110 increases the value of the counter by one in step 342 and proceeds to step 312. A guide message for inputting a password is read from the DSP 120 and resent. When the value of the counter is set in step 340, the CPU 110 proceeds to step 346 to set the counter, and then proceeds to step 336 to block the transmission loop. Otherwise, if the correct password is input, the CPU 110 controls the DSP 120 to read and send a guide message for inputting the data number of the image data to be received in step 316. In addition, the CPU 110 determines whether a data number has been input in step 318, and in step 320, a guidance message asking whether to transmit or delete the image data selected by the input data number from the DSP 120. Read and send. In response to the guide message, the CPU 110 determines whether a start key for sending an image message selected in step 322 is input from the corresponding facsimile apparatus. If the start key is input, the CPU 110 corresponds to the data number selected in step 318. The resulting image data is controlled by the HDD 118 and read out from the hard disk having the format of FIG. 4C. When the transmission of the image data is finished, the CPU 110 reads out the DSP 120 from the DSP 120 to input a data number to delete the transmitted image data or to select new image data. However, when the delete key is inputted from the corresponding facsimile apparatus in step 328 in response to the guide message sent in step 320, the CPU 110 proceeds to step 330 to display the image data sent in step 324 to the HDD 118. After the control is deleted from the hard disk, the control proceeds to step 326. In addition, when the deletion key is detected in step 328 in response to the guide message sent in step 326, the process proceeds to step 330 to perform the deletion process. Since the deletion process has been described above, it will be omitted. If the deletion key is not detected in step 328 in response to the guide message sent in step 326, the CPU 110 controls the HDD 118 to control the HDD 118 to transmit the image data sent in step 324 in step 332. After resaving, proceed to step 334. In step 334, the CPU 110 determines whether a data number for selecting new image data is input in response to the guide message sent out in step 326, and if a data number for selecting new image data is input, step 320. Proceeds to the process of transmitting the selected image data. Since the delivery process has been described above, it will be omitted. Otherwise, if there is no input of a new data number, the CPU 110 proceeds to step 336 and detects that the transfer is completed. In step 346, the transfer loop for controlling the line interface unit 112 to transmit image data. To block.

As described above, the present invention selects and receives the image data received from the transmitting side facsimile apparatus, so that there is an effect of blocking unnecessary image data as information communication develops. In addition, it is possible to reduce the waste of the recording paper due to the reception of unnecessary image data, and to eliminate the reception failure due to the lack of the recording paper.
