Description

Method for storing and transmitting fax data

The present invention relates to a method for storing and transmitting fax data, and more particularly, when a fax or multifunction device reads an original to be transmitted at the time of memory transmission and stores it in a memory, there is not enough space to store the fax data. memory full) ', and it relates to a method of storing and transmitting fax data to solve this problem.

In general, a facsimile is an office device for fax data communication such as a document or a picture using a public circuit network. As various functions are gradually added in recent years, a facsimile has a built-in memory in addition to a function of reading an original and sending it directly. A memory transmission function has been proposed for storing read fax data in memory and transmitting it. In addition, a multifunction terminal called Multi Function Peripheral (MFP), which integrates the functions of single-use terminals such as printers, copiers, and scanners, other than office equipment, is performed. Also used.

To send the fax data to the other party, the fax inserts the original, enters the receiving party's identifier number, selects Start, and then calls the receiving party and forms a call path according to the receiving party's response. When read, the read fax data is transmitted to the receiving side. In such an original transmission, the user had to insert and transmit the original every time a retransmission was performed even when the same original was transmitted. Memory transmission is an added function for the convenience of the user, which is to store originals to be transmitted in a memory and transmit them to a receiving side. This feature can be used when the user cannot send fax data directly, such as group transmissions that can send fax data to multiple recipients, or broadcast transmissions, and timed transmissions that send fax data after a certain period of time. This is useful if you do. In addition, in order to perform a simultaneous execution function or a multitasking function that allows another facsimile function to be performed during the original transmission, the original transmission must be performed by a memory transmission method. For example, other sender reservation functions may be performed during memory transmission, or report output and general document copying may be performed during memory transmission. Thus, when multiple users use the facsimile in common, the first user will be able to use the other facsimile functions while performing the memory transfer.

The conventional memory transmission method will be described below.

First, insert an original, enter the receiving party's identifier number, and select the memory transmission function to start reading the original. The read originals are stored in the memory, and when the free space of the memory is insufficient to store the read originals, the memory pool occurs. This often happens when multiple users use a facsimile. Conventionally, when a "memory pool" occurs when reading a manuscript, execution of the memory transmission is terminated.

A method of storing fax data in order to perform a conventional memory transmission will now be described in detail with reference to FIG. 1. When the original starts to be read for storing the fax data (S10), the read original data is encoded (S11). In this case, the encoding uses a Modified Modified Read (MMR) scheme, and when encoded by a predetermined size, the encoded fax data is stored in a memory (S12). After the fax data is stored, it is determined whether there is free space in the memory (S13), and if there is no more free space in the memory, after displaying 'Memory Pool' on the display window of the operation panel (S14), the storing step At S12, the stored fax data is deleted and the performance of the memory transmission is completely terminated. If there is free space in the memory, it is determined whether the storage of the read original is completed (S15), and the above steps (S11 to S15) are repeated until all the originals are read and the read data is encoded and stored. Exit when the save is complete. Thereafter, the stored fax data is simply transmitted to one receiving side or the memory transmission is performed in accordance with a preset condition set by the user, for example, selection of a dialing function such as multiple transmission or time delay transmission.

However, in the conventional memory transmission method as described above, if a 'memory pool' occurs during the reading and storing of the original, it is displayed on the display window of the operation panel and the memory transmission function itself is terminated. The trouble of having to execute multiple transmissions has become a problem.

In addition, when a user needs to perform a memory transmission, the user can wait until the 'memory pool' does not occur and then execute the memory transmission function after the memory is allocated because the fax data stored in the memory is deleted, thus wasting time. There was this.

In addition, if the "memory pool" occurs frequently, there is a problem that the cost is increased by adding memory.

Accordingly, an object of the present invention is to solve the above-described problems, and an object of the present invention is to provide a memory transmission method by repeatedly storing and transmitting fax data when a memory pool occurs. The present invention provides a method for storing and transmitting fax data so that memory transmission is not terminated.

Another object of the present invention is to provide a method of storing and transmitting fax data such that transmission of fax data can be completed by performing memory transmission in a current memory state without adding a memory.

A feature of the present invention for achieving the above objects is a memory transmission function for storing fax data read from an original in a fax data communication in a memory and transmitting the fax data stored in the memory according to a set condition: A first judging step of judging whether there is a free space in a memory for storing read and encoded fax data; In the first judging step, if there is no space for storing the fax data in the memory, it is determined whether the dialing condition is possible immediately, and if a call path is formed, the fax data stored in the memory is transmitted until the first judging step. A transmission / deletion step of deleting the transmitted fax data; And a storage step of storing encoded fax data when the storage space of the memory is allocated in the first determination step.

In the above-described feature of the present invention, the transmitting / deleting step includes: reading / deleting step of reading fax data stored in the memory and then deleting it from the memory when a call path is formed by dialing to a receiving side; A modulating step of modulating the read fax data; A temporary storage step of temporarily storing the modulated fax data in a buffer; And a second determining step of transmitting the temporarily stored fax data and determining whether all of the transmissions are completed.

In another aspect of the present invention described above, in the storing step, the read fax data is encoded and stored in a block unit in memory.

Hereinafter, a method of storing and transmitting fax data during memory transmission according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing the configuration of a facsimile for practicing the present invention.

The control unit 100 for controlling the system according to a predetermined program, the protocol data and text data, etc. are stored in the memory 110 for accessing or storing the data under the control of the control unit 100, used in the control unit 100 RAM 120 temporarily storing the variable and the data received from the public network, ROM 130 for storing the data necessary for the control unit 100 to operate the program, and a plurality of keys for inputting the key data is provided When the key data is generated, it is input to the control unit 100 and an operation panel 140 having a display window for displaying the display data of the control unit 100, and an original is read to provide the read data to the control unit 100. Scanner 150, data read by the scanner for copying the original, data received from the public line network or various functions of the facsimile. A printer 160 for outputting a report, a modem 170 for demodulating and outputting an analog signal received by modulating the output data into an analog signal under the control of the controller 100, and a signal of a public circuit network. It consists of a Line Interface Unit (LIU) 180 for interfacing. If the control unit 100 controls the overall system and selects memory transmission with a function key of the operation panel 140, the document is read by the scanner 150, and the encoded fax data is stored in the memory 110, and then the modem 170 is connected with the modem 170. It is output to the LIU 180 and transmitted to the receiving side through the public circuit.

3 is a flowchart for carrying out the present invention.

The implementation of the present invention can be largely divided into a data storage portion and a data transmission portion. First, when an original is inserted and the memory transmission is selected, and the identifier number of the receiving side is inputted, the reading of the original is started, and the read original data is encoded in blocks and stored in the memory 110. If encoding is started (S31), and the encoded fax data is generated by one block size (S32), it is determined whether there is free space to be stored in the memory 110 (S33). If there is a space to store, after storing the encoded block data (S34), it is determined whether all the fax data of the read original is stored (S35). The steps S31 to S35 are repeated until all of the fax data is stored in the memory 110 or a 'memory pool' occurs during storage, and then ends when the storage of the fax data is completed. The stored fax data is stored in the memory 110 until memory transmission according to various preset dialing functions is executed, and is deleted from the memory 110 after the transmission is completed. If there is no space to be stored in the memory 110 during storage, it is determined whether or not a condition is possible to immediately dial to the preset receiving side so that the fax data can be transmitted (S36). For example, the case where there is one set receiving side is a condition that can be dialed, and the group transmission or the like cannot be a condition that can be dialed. If it is possible to dial, it dials to the receiving side (S37) to determine whether a call path is formed (S38). If a communication path is not formed, an error occurred in the connection with the receiving side is displayed on the display window of the operation panel 140 and terminates. When the call path is formed, the fax data is deleted from the memory 110 while reading the fax data stored in the memory 110 (S39). The read fax data is modulated into a signal transmittable by the modem 170 (S40). The modulated signal is temporarily stored in the buffer of the modem 170 (S41) and transmitted to the receiving side (S42). Thereafter, it is determined whether the transmission is completed (S43), and when the transmission of all the originals is completed, the transmission is terminated, or the process proceeds to the step S31 again to read and store the next original until the transmission is completed, and the above steps are performed. Repeat (S31 ~ S42).

Therefore, according to the method for storing and transmitting the fax data in the memory according to the present invention, even if a 'memory pool' occurs when reading the original for transmission, the performance of the memory transmission is not terminated, but the fax data is stored in the memory. When encoding and storing in block units, the stored fax data up to the point where the 'memory pool' is generated is sent to the receiving side first, the transmitted fax data is deleted from the memory, and the original is read again, and the block data is stored as much as the free space in the memory. By repeatedly performing the step of transmitting the stored data, the transmission of the fax data can be completed.

After all, according to the method of storing and transmitting the fax data in the memory in the facsimile or multifunction apparatus according to the present invention, when the 'memory pool' occurs due to insufficient memory, the first block is read and encoded until the 'memory pool' occurs. By sending the fax data stored in the memory in units, deleting it from the memory, and reading and storing the next original again, and then transmitting it, that is, dividing the entire original to perform reading, storing and sending, thereby completing the transmission of the original. When sending fax data in memory, even if a large amount of originals are sent or fax data stored in the memory has not yet been deleted, even if the free space allocated to the memory is less than the amount of fax data of the read originals, due to the 'Memory Pool' There is an advantage that the transmission of the original can be made without being generated.

Also, the fax itself completes the transmission of the fax data by repeating the original reading, memory storage, and memory transmission until the memory transmission of the original is completed, so that the user can send the original when the 'memory pool' occurs and transmission ends. In order to complete the transmission by reading the original once without the hassle of performing the same operation repeatedly, there is an advantage that the user can be convenient and the waste of time required can be reduced accordingly.
