Abstract

PROBLEM TO BE SOLVED: To prevent as for as possible a state where a memory overflows during accumulation of information and only incomplete information is accumu lated and to conduct stable accumulation. SOLUTION: A memory residual amount detection means 9 detects the memory residual amount M of a memory 30. A threshold generation means 41 outputs a threshold Mth on the memory residual amount of the memory 30. A comparison means 53 compares the memory residual amount M detected by the memory residual amount detection means 9 with the threshold Mth outputted from the threshold generation means 41. A priority judgment means 51 judges priority on permission of accumulation to the memory 30. When the comparison means 53 judges that the memory residual amount M becomes lower than the threshold Mth, a selection means 52 selects an accumulation operation for permitting accumulation to the memory 30 in accordance with priority.

Description of the Related Art Conventionally, a facsimile apparatus having an image memory for storing image data, and a communication terminal connected to a network and having a function of temporarily storing various information such as character data and numerical data. The device is widespread.

However, the storage capacity of the memory is limited in terms of cost and space, and it is difficult to secure a sufficient storage capacity. For this reason, in many cases, the memory cannot be continued due to a shortage of the remaining memory while the information is being accumulated, and various improvements have been attempted to cope with such inconvenience.

For example, Japanese Patent Application Laid-Open Nos. 63-2336644, 63-2336645, and 1-1
No. 83266 discloses a facsimile apparatus in which image data is stored when the remaining amount of image memory reaches a predetermined threshold during the storage of document information in order to ensure that image transmission can be performed without overflow of the image memory.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a functional block diagram of the present invention.

The memory 30 stores various information such as image data, character data and numerical data. The remaining memory detecting means 9 detects the remaining memory M of the memory 30. The threshold generation unit 41 outputs a threshold Mth relating to the remaining memory capacity of the memory 30.

The comparing means 53 comprises a memory remaining amount M detected by the memory remaining amount detecting means 9 and a threshold generating means 41.
Is compared with the threshold value Mth output from. The priority determination unit 51 determines a priority regarding permission for accumulation in the memory 30.

When the comparing means 53 determines that the remaining memory amount M has fallen below the threshold value Mth, the selecting means 52
An accumulation operation that permits accumulation in the memory 30 is selected according to the priority order.

In such a configuration, the storage operation A for storing the information a is started from the state where the remaining amount of memory M exceeds the threshold Mth, and further, the storage operation B for storing the information b.
Is started, the accumulation operations A and B are performed in parallel.

If the remaining amount of memory M falls below the threshold value Mth while the accumulation operations are being performed in parallel in this manner, the priority order of the accumulation operation A and the accumulation operation B is judged by the priority judgment means 51. .

Here, for example, if the accumulation operation A has a higher priority, only the accumulation operation A is selected by the selecting means 52, so that the accumulation of the information a is continued and the accumulation of the information b is interrupted. Therefore, it is possible to avoid a situation in which the remaining amount of memory in the memory 30 decreases due to the information b by the accumulation operation B having a low priority and the information a having a high priority cannot be completely stored.

FIG. 2 is a schematic block diagram of a facsimile apparatus to which the present invention is applied.

The reading unit 1 is, for example, an image scanner, and reads document information and converts it into image data of an electric signal. The image processing unit 2 encodes the image data and decodes the encoded image data. The image memory 3 stores the encoded image data. The remaining memory detecting unit 9 detects the remaining memory M of the image memory 3. A line control unit (NCU) 6 performs connection, disconnection, incoming call detection, and the like between various line networks and the facsimile machine.

The printer unit 7 prints out the received image data on recording paper. The operation panel 8 includes a numeric keypad,
It has a function key, a display unit, and the like. The RAM 4 provides a work area and stores data set by the user from the operation panel 8 and the like. The ROM 10 stores a control program for operating the present system, various basic data, and the like, and also stores the threshold Mth described with reference to FIG. The main control unit (CPU) 5 operates according to a control program stored in the ROM 10, and operates as shown in FIG.
The function of the comparison means and the selection means described with respect to the above is achieved.

Next, the operation of the embodiment of the present invention will be described with reference to the flowchart of FIG. In this embodiment, in addition to the first threshold value Mth1 generated by the threshold value generation means 41,
A second threshold Mth2 representing a physical memory full state is provided. In the following, the first threshold Mth1 is 30
% And the second threshold value Mth2 are set to 0%.

When at least two or more storage operations are being performed, such as memory reception on two channels or memory reception and transmission original storage, step S1
At 0, the memory remaining amount M of the image memory 3 is detected by the memory remaining amount detecting unit 9 and the memory remaining amount M is set to the first threshold Mth.
1 (30%) is determined. If not, it is determined in step S11 whether or not the reception has been completed. When the reception has been completed, the process ends.

If it is determined in step S10 that the remaining amount of memory M is less than the first threshold value Mth1, in step S12 the priorities of a plurality of storage operations being executed are determined, and the storage operations with lower priorities are determined. Operation is aborted.

FIG. 4 shows an example of a criterion for judging the priority. FIG. 4A shows a judgment for judging the priority according to what kind of job each image data relates to. As a reference, the priority of a job that stores received image data is the highest, and the priority of a job that stores image data of a transmission original is the lowest.

FIG. 2B shows a criterion for determining the priority order according to which partner station each image data is transmitted from, and the identification number of the partner station (for example, telephone number). ) Is determined based on the number.

When the low-priority storage operation selected in this manner is stopped, the image data partially stored by the storage operation is erased from the image memory to recover the remaining memory. Is desirable.

If the job whose storage has been stopped is a received job, a retransmission request or the like may be sent out after the remaining memory is restored to request the image data to be sent out again.

As described above, when the accumulation operation with a low priority is stopped, the remaining memory M of the image memory 3 is detected by the remaining memory detector 9 in step S13. If the remaining memory capacity M is sufficient, the operation is continued in step S14, and if it is determined that the remaining memory capacity M has reached the second threshold value Mth2, in step S15, all the accumulating operations being executed are terminated. You.

According to the present embodiment, when the remaining amount of the image memory falls below the predetermined value during execution of a plurality of accumulation operations, the accumulation operation with a low priority is stopped. The accumulation of data does not hinder the accumulation of high-priority image data.

In the above embodiment, the priority of the storage operation is determined according to the contents of the job and the transmission partner. However, the priority is determined according to whether the communication mode is G3 or G4. You may do it. When the determination is made based on the communication mode, it is desirable to set the priority of the G3 mode to be higher.

In this way, when the storage operation in the G3 mode and the storage operation in the G4 mode compete with each other, the storage operation in the G4 mode having a high communication speed is stopped, so that the reception time when receiving data again is reduced. become able to.

In addition, when one of the storage operations is related to real-time printing and the print operation is started, the priority of the storage operation may be made highest. In this way, the recording paper that has been printed out halfway is not wasted.

Also, in the above-described embodiment, only the operation with the lowest priority among the plurality of storage operations has been described as being stopped. However, the present invention is not limited to this, and the storage operation with the highest priority is performed. Stop everything except
It is also possible to stop a plurality of storage operations having a low priority and continue the remaining plurality of storage operations.

In the above embodiment, the present invention is applied to a facsimile apparatus. However, the present invention is not limited to this, and is connected to various networks such as a file server and a print server. The present invention can be similarly applied to various communication terminal devices having a storage function.

[0036]

As described above, according to the present invention, the following effects are achieved. (1) When the remaining amount of memory is equal to or less than a preset value, one of the operation of storing the print information received from the network in the image memory and the operation of storing the copy information in the image memory is not performed. Information can be reliably stored by the other storage operation. (2) When the remaining memory is less than a preset value, the operation of storing the copy information in the image memory is not performed, so that the print information can be reliably stored, and the recording paper that has been printed out halfway is wasted. do not become.
