Abstract

PURPOSE: To copy plural pages into a memory without fully using the memory area of a storage means by synchronizing the read operation and the recording operation in the unit of pages. CONSTITUTION: An original is read by a contact sensor(CS) 9 and compress- coded through a read control gate array (R-CNT) 10 and stored in an image memory (DRAM) 13. In this case, a read task is started and a read original is sent, then a read page number and a recording page number are compared, and when the read page number is not advanced from the recording page by one page or over, a succeeding original is read. When the read page number is advanced from the recording page by one page or over, the read operation is awaited till a difference between the recording page number and the read page number is within one page. The read task allocates the image memory 13 to read a succeeding page and reads the image and stores the image to the image memory.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine.

[0002]

2. Description of the Related Art Conventionally, a facsimile apparatus provided with an image memory for storing image data, particularly, a reading operation for storing a read document in the memory and a recording operation for recording the image data stored in the memory are simultaneously performed. In the facsimile apparatus capable of performing the above, the memory copy function operates asynchronously with the reading operation and the recording operation. In the reading operation, reading is performed until the original is exhausted, and in the recording operation, recording is performed until there is no image data in the memory.

[0003]

However, in such a memory copy function, when a large number of pages are copied to a memory, the read image data is stored in the memory rather than recording the image data and releasing the memory. Since the memory is full, the memory capacity becomes full, and the copy function ends in error on the spot.

Therefore, it is inconvenient for the user to copy again. Further, even if the reading operation ends because the speed of the reading operation is different from that of the recording operation, the user feels annoyed because the recording operation is in a state of recording several pages before.

According to the present invention, by synchronizing the reading operation and the recording operation on a page-by-page basis, it is possible to copy the entire original document in a single copying operation without filling the memory capacity. An object of the present invention is to provide a facsimile apparatus that can eliminate the troublesomeness by terminating the reading operation without much difference.

[0006]

According to a first aspect of the present invention, there is provided a facsimile apparatus which stores storage means for storing image data, allocates the storage means for the image data, and stores the image data in the storage means. A facsimile apparatus having a reading unit and a recording unit for recording the image data stored in the storage unit and releasing the allocated storage unit after the recording is completed, and performing the reading operation and the recording operation at the same time. And a recording control means for monitoring the page number of the recording means at the time of memory copying, and a reading control means for executing or waiting the reading means according to the page number obtained by the recording control means. .

According to a second aspect of the present invention, in the facsimile apparatus, the reading means for waiting the reading means at the end of the reading operation for the next page of the page on which the recording means is recording, and the recording means. It is characterized in that it has a reading continuation means for continuing the reading means to read the next page when the recording is completed.

[0008]

According to the structure of the first aspect, by synchronizing the reading operation and the recording operation on a page-by-page basis, a plurality of pages of memory can be copied without using the memory area of the storage means to the full. Becomes

According to the second aspect of the present invention, the reading operation is preceded by the recording operation by one page, so that the memory unit can perform the memory copy only by holding the storage area for two pages, and the capacity is small. A page memory is also possible in the facsimile device of the storage means. Also,
Since the operation of the reading unit and the operation of the recording unit are only one page difference, the reading operation and the recording operation can be completed without a great difference, so that the user can be free from trouble.

A CPU (Central Processing Unit) 1 is a ROM
The entire apparatus is controlled according to the contents of the program stored in the (read only memory) 2.

The original is read by the contact sensor (CS) 9 and read control gate array (R-CNT) 1
Image code (DRAM) 1 compressed and encoded through 0
3 and the recording management information such as the reception number, the destination information, the number of pages, the stored image memory block information, the resolution and the image size are stored in the first RAM 4.

The image information stored in the image memory 13 and the recording management information stored in the first RAM 4 are stored in the CPU.
When there is a recording request from the recording control gate array (W-
The data is decompressed and decoded by the CNT 11 and recorded on the recording paper by the laser printer (LBP) 12.

When the CPU 1 issues a transmission request, the image information stored in the image memory 13 is compression-encoded by the CPU 1 according to the mode of the partner device, and the modulation demodulator (MODEM) 14 performs PM-AM modulation. Then, it is output to the line through the network control unit (NCU) 15.

The image data received through the line is also modulated and demodulated by the network control unit 15.
4 and demodulated by the modulation demodulator 14 and CP
The data is decompressed and decoded by U1, the image error is checked, and if it is correct, it is compression-decoded by the CPU1 and then stored in the image memory 13 and the management information in the first RAM 4.

Further, the operator can perform various instructions and settings and input of information by pressing various keys on the key (KEY) board 8 which is the information input means. The content of the input information is the second RA
It can be confirmed by being stored and stored in M5 and displayed on the display unit (LCD) 7.

In this case, the CPU 1 detects key input data from the keyboard 8 through the operation panel control gate array (OP-CNT) 6 and causes the display unit 7 to display necessary data. Further, in the standby state, the CPU 1
The current date, time, etc. are obtained from the information from the (real time clock) 3 and displayed on the display unit 7.

Next, the processing operation procedure in the facsimile apparatus having the above-mentioned configuration will be described with reference to the flowcharts of FIGS.

FIG. 2 is a flow chart showing the operation of the read task during memory copy.

The reading task is started when the manuscript is set and the copy key of the keyboard 8 is pressed (S1). When the reading task is activated and the reading original is set (S2), the reading page number (Rn) is compared with the recording page number (Wn) (S3), and the reading page number is one or more pages ahead of the recording page number. If not, scan the next original.

When the read page number is ahead of the recorded page number by one page or more, the reading operation is in a waiting state until the difference between the recorded page number and the read page number is within one page.

The reading task allocates the image memory 13 to read the next page (S4), reads the image, and stores it in the image memory (S5). Then, the read page number is counted by one page (S6), and the process returns to the first process to check whether there is a next document. When there is no document (S2), the reading operation is terminated (S2).
7).

FIG. 3 is a flow chart showing the operation of the recording task at the time of memory copy.

First, the recording task is started when a document is set and the copy key of the keyboard 8 is pressed (S).
9). When the recording task is activated, it is detected whether or not there is one page of stored image data (S10).
The system waits until the reading of one page is completed.

When there is one page of image data to be recorded, the recording page number (Wn) is counted up, one page is recorded (S12), and after the recording is completed, the image memory of the recorded page is released. (S13).

Then, it is judged whether or not all pages have been recorded (S14), and if there is a next page to be recorded,
Returning to the first operation, when the recording of all pages is completed, the recording task is ended.

[0027]

As described above, according to the first aspect of the present invention.
According to this, when a large number of pages are copied to a memory, the reading task and the recording task are synchronized in page units even when the reading task for storing the read image data in the memory is faster than the recording task for the image data. As a result, the entire original can be copied in one copy operation without filling the memory capacity.

According to the second aspect of the present invention, by setting the difference between the reading operation and the recording operation to be one page, all the originals can be copied in one copying operation without filling the memory capacity. Further, by ending the recording operation and the reading operation without much difference, it is possible to eliminate the troublesomeness for the user.
