BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having a memory receiving function for temporarily storing received image data in a memory.

[0002]

2. Description of the Related Art Conventionally, a facsimile apparatus of this type temporarily stores received image data in a memory and then reads out the image data stored in the memory when an instruction to output the image data stored in the memory is given. Then, this is displayed on the display unit or printed from a printer on recording paper and output. By the way, since the capacity of the memory is limited, in some cases, the memory may be filled with image data during memory reception, and the received image data cannot be stored in the memory anymore. There was a drawback that received image data that could not fit in would be lost. When the operator outputs the image data received by the memory and finds a communication in which the memory is full and the transmission original is cut off as described above,
If you know the sender, you can take measures such as re-sending, but if you do not know the sender, you cannot resend it, and there is the disadvantage that information will eventually be lost. It was

[0003]

As described above, in the facsimile apparatus having the memory receiving function, if the memory is full during the reception of the memory, the received image data not stored in the memory will be lost, and the information will be lost. There was a drawback that it was missing.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to eliminate the above-mentioned drawbacks and to provide a facsimile apparatus which can secure the remaining received image data even if the memory is full of image data during receiving the memory.

[0005]

According to the present invention, there is provided a fax machine having a memory receiving function for storing received image data in a memory and a receiving function for printing the received image data on a recording paper and outputting the same, when receiving the memory. Detecting means for detecting that the memory is full of image data, and when the detecting means detects that the memory is full, the received image data after that is printed and output on a recording paper. And a switching means.

In a fax machine having a memory receiving function of storing received image data in a memory and a receiving function of printing the received image data on a recording sheet and outputting the received image data as a configuration different from the above configuration, when the memory is receiving, First detecting means for detecting that the remaining capacity capable of accumulating image data in the memory is below a predetermined value, and when the first detecting means detects that the remaining capacity is below a predetermined value. , And a switching means for printing the received image data after that on a recording sheet and outputting the same.

[0007]

In the fax machine of the present invention, the detecting means detects that the memory is full of image data when receiving the memory. When the detecting means detects that the memory is full, the switching means prints the received image data after that on a recording paper and outputs it.

In the fax machine having an operation different from the above operation, the first detecting means detects, when the memory is received, that the remaining capacity capable of accumulating the image data in the memory becomes less than a predetermined value. When the first detecting means detects that the remaining capacity has become equal to or less than a predetermined value, the switching means prints the received image data after that and prints it on recording paper and outputs it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the facsimile apparatus of the present invention. 1 is a CPU that performs normal communication control and memory reception control, 2 is an NCU that captures and releases lines, 3 is a modem that modifies and demodulates data, 4 is an image memory that stores image data, and 5 is A memory control unit that controls reading and writing of image data from and to the image memory 4 (hereinafter referred to as a memory), 6 is a printer that prints the image data on recording paper and outputs it, and 7 is a printer that converts the image data into print data and a printer A printer control unit for controlling the operation of 6 and a telephone line.

Next, the operation of this embodiment will be described. N
The image data received by the CU 2 is demodulated by the modem 3 and then sent to the memory control unit 5 by the CPU 1. The memory control unit 5 writes the sent image data in the memory 4 and accumulates it. At this time, the CPU 1 performs control as shown in the flowchart of FIG. 2 according to the information from the memory control unit 5. During memory reception, the CPU 1 determines in step 201 whether or not the memory 4 is full of image data. If not, step 202
Then, the memory reception is continued and the process returns to step 201 to repeat the above determination. If it is determined in step 201 that the memory 4 is full of the stored image data and the received image data cannot be stored in the memory 4 any more, the process proceeds to step 203, and the image data received thereafter is transferred to the printer control unit 7. To the printer 6 via. As a result, the image data received after the memory 4 is full is printed on the recording paper by the printer 6 and output.

According to the present embodiment, when the memory 4 is filled with the received image data during the memory reception, the image data received thereafter is printed on the recording paper from the printer 6 and is output. Even if it becomes full during reception, the remaining received image data can be printed and secured on recording paper without being lost.

By the way, in the above embodiment, since the memory 4 is full, the image data received thereafter is printed by the printer 6.
When performing switching to send to and print on recording paper and output, part of the image data received at the time of switching is not accumulated in the memory 4 and is not printed and output from the printer 6 on recording paper. There is a possibility that some of the received image data may be lost.

FIG. 3 is a flow chart for explaining another embodiment of the present invention which avoids the drawbacks of the above embodiment. In this example, the structure of the facsimile apparatus is similar to that of the previous embodiment shown in FIG. CPU 1 of this example
During the memory reception, in step 301, it is checked through the memory control unit 5 whether the remaining storage capacity of the memory 4 (hereinafter referred to as remaining capacity) is smaller than a predetermined amount, and the memory capacity equal to or larger than the predetermined amount is checked. If there is any, step 3
Go to 02 and continue the above memory reception, and again step 3
The above check is repeated at 01. When the CPU 1 determines in step 301 that the remaining capacity of the memory 4 has become less than the predetermined amount, the process proceeds to step 303, in which the received image data obtained from the modem 3 is sent to the memory control unit 5 and the memory 4 At the same time, the image data is sent to the printer control unit 7, and the image data is printed on the recording paper from the printer 6 and output. Thereafter, in step 304, the CPU 1 determines whether or not the memory 4 is full of accumulated image data, and if it is determined that the memory 4 is not full, step 3
Return to 03, if it is determined that it is full, step 3
Go to 05. In step 305, the CPU 1 stops the operation of accumulating the received image data in the memory 4, and simply causes the printer 6 to output the image data received thereafter.

According to the present embodiment, when the remaining capacity of the memory 4 becomes less than a predetermined amount during the memory reception, the memory reception and the recording paper reception are used together until the memory 4 becomes full thereafter. Therefore, it is possible to prevent some reception data from being lost when switching from memory reception to recording paper reception as in the previous embodiment, and to secure all received image data without missing information. You can
