Memory management method when sending memory

The present invention relates to a memory management method for memory transmission, and more particularly, to efficiently manage memory in storing and transmitting originals read in a memory when a fax or multifunction device performs transmission of fax data by memory transmission. It is about a method.

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

To send the fax data to the other party from the fax or multifunction device, insert the original, enter the receiving party's identifier number, select Start, call the receiving party, and when the telephone line is established according to the receiving party's response, The read fax data is transmitted to the receiving side while being read by. 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 allows users to send fax data immediately, such as group transmissions that send fax data to multiple recipients, or broadcast transmissions, and timed transmissions that send fax data after a certain period of time. It is useful in the case. 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 a memory transmission. 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. Therefore, even if several users use the facsimile in common, the first user can use another facsimile function while executing the memory transmission.

The memory transmission performed in this conventional facsimile is as follows.

1 is a flowchart illustrating a memory transmission method performed in a conventional facsimile. First, in order to transmit the fax data, the user inserts the document into the document glass (S10), selects a memory transmission function, and then inputs a receiver ID number to be transmitted (S11). When the user presses the start button, reading of the original is started (S12), and the read fax data is stored in the memory (S13). At the time of storage, it is determined whether or not a memory pool has occurred (S14). If the memory pool occurs because the memory space where the read fax data can no longer be stored is insufficient, the fax data stored in the memory is deleted by reading the original, and the occurrence of 'Memory Pool' appears on the display of the control panel. Next displayed (S15), the memory transmission function is terminated.

If the memory pool is not generated, it is determined whether a communication path by a protocol is transmitted and received according to the set transmission condition (S16), and when the communication path is formed, the stored fax data is transmitted to the receiving side (S17). If no communication path is established, an error has occurred in the connection with the receiver and the display is terminated. Depending on the device, the device automatically tries to redial the number of times and then terminates. When the transmission is completed, the entire transmitted fax data stored in the memory is automatically deleted (S18) and the memory transmission function is terminated.

At this time, if there are too many originals to be read and stored, the fax data storage memory portion of the fax becomes full. Then, the memory pool is generated so that the fax data is no longer stored and memory transmission cannot be performed accordingly, so the user has to divide the original and execute memory transmission again or perform direct transmission.

In addition, when using a limited memory, priority is given to the first user when multiple users use it. Therefore, when the first user stores a large amount of fax data in the memory, the user who uses it later stores the memory. When the original is read while the preceding memory transmission is still in progress, the free space remaining in the memory is insufficient, resulting in a memory pool. This is because the fax data stored in the memory is deleted after the original read out at the time of memory transmission is completed to the receiving side.

By the way, in the memory transmission of the conventional facsimile or multifunction device as described above, since the fax data stored in the memory is deleted after the memory transmission to the receiving side is completed, before the fax data is deleted, that is, before the memory transmission is completed. When the next user is used, the memory pool frequently occurs, and therefore, the next user is troublesome and wastes of time to send the fax several times for retransmission after a certain time.

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 provide a method for efficiently managing a memory in performing a memory transmission in order to reduce the occurrence of a memory pool.

In addition, another object of the present invention is to provide a memory management method for transmitting fax data stored in a memory and deleting from the memory so that a memory pool is not generated with a current built-in memory without adding a memory.

A feature of the present invention for achieving the above objects is a memory transmission in which a document is read in a multifunction device, stored in a memory, and then transmitted to the receiving end: transmission of the fax data stored in the memory in a predetermined unit. A checking step of checking whether the transmission is normally completed; A deleting step of deleting the transmitted fax data of the predetermined unit from the memory if transmission is normally completed; And a determining step of determining whether the transmitted original is the last original, and repeating the checking step and the determining step until the transmission of the last original is completed. have.

In the above-described features of the present invention, the multifunction apparatus preferably performs the function of a facsimile.

In another aspect of the present invention described above, it is preferable that the deleting step is a page unit of a read original document.

Hereinafter, a method of managing a memory when the memory transmission according to the present invention is performed 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.

In the control unit 100 for storing the control unit 100, protocol data and text data, etc. for controlling the system according to a predetermined program, and for accessing or storing the fax data under the control of the control unit 100, the control unit 100 RAM 120 temporarily storing the variable to be used and the fax data received from the public line network, the ROM 130 storing the fax data necessary for the control unit 100 to operate the program, and a plurality of keys for inputting the key data. Is provided to input it to the control unit 100 when key data is generated, the control panel 140 having a display window for displaying the display data of the control unit 100, a scanner 150 for reading an original, and a public circuit network. The printer 160 for outputting the received fax data and reports of various functions of the fax, and the control unit 1 under the control of the control unit 100. 00) is configured of a modem 170 for modulating and outputting the output data of an analog signal, and demodulating and outputting a signal received analog, and a LIU (Line Interface Unit) 180 for interfacing a signal of a public line network. The control unit 100 controls the overall system, and when the memory transmission is selected by the function key of the operation panel 140, the original is read by the scanner 150, and after the fax data is stored in the memory 110, the modem 170 and the LIU ( 180) and is transmitted to the receiver through the public circuit.

3 is a flowchart for carrying out the present invention.

First, in order to transmit the fax data, the user inserts the document into the document glass (S30), selects the memory transmission function (S31), and then inputs a receiver ID number to be transmitted (S32). When the user presses the start button, the original is read by the scanner 150 (S33), and the read fax data is stored in the memory 110 (S34). At this time, the control variables for transmitting the fax data, for example, when storing the fax data is divided into page units, the storage location of each page, the location where the actual fax data starts, and the resolution for transmitting the fax data, etc. Stored with the fax data. Thereafter, the receiving side is called according to the preset memory transmission condition without any other operation (S35). This is a call connection with the set identifier number. When a response is received from the receiver and a call path is formed (S36), the control variables initialized to transmit the fax data are set to stored values, and when a CFR (Confirmation to receive) is received from the receiver, the memory 110 is received. Fax data stored in units of pages is modulated by the modem 170 and transmitted to the receiving side through the public line network (S37). When the transmission of one page is completed, a multi-page signal (MPS) or end of page (EOP) signal is transmitted to the receiver. Thereafter, it is determined whether the transmission of the corresponding page is normally completed (S38). It is confirmed whether a successful transmission of the message confirms that an NCF (Message Confirmation) signal is received. If the receiving side can no longer receive, the transmission stops and ends. If the transmission of one page is normally completed, the corresponding transmitted page is deleted from the memory 110 (S39). Accordingly, about one page of memory space may be allocated to another user in the memory 110. Next, it is determined whether all the fax data has been transmitted (S40), and the existence of the next page is checked. When the transmission of all the fax data stored in the memory 110 is completed by repeating the above steps until all the pages are transmitted, the transmitted fax data does not remain in the memory 110. In this way, pages are deleted in the order in which they are sent, which allows more memory 110 to be allocated to other users.

Therefore, according to the memory management method according to the present invention, by transmitting the fax data stored by one page at the time of memory transmission and immediately deleting the corresponding page when the transmission is completed normally, the memory can be further provided to the next user. It will be possible.

As a result, according to the memory management method for memory transmission according to the present invention, the transmission status is checked every time a page is transmitted when the fax data stored in the memory is transmitted, and the corresponding page transmitted is deleted to efficiently manage the memory even in a small memory. Therefore, there is an advantage that the inconvenience of the user can be reduced by reducing the occurrence of the memory pool when the memory transmission function is used.

In addition, since a plurality of users can use the memory smoothly, there is an advantage that the cost can not be increased because the transfer can be performed to the small memory currently embedded without adding memory.
