Abstract

PURPOSE:To attain ease of connection of a recording paper sheet and reproduction at the reception side by recording a split processing mark or a split position mark on the recording paper sheet in splitting picture data by overflow of a picture memory. CONSTITUTION:A picture on an original 1 is lighted by a light source 7 and its reflected light 8 is formed on a CCD sensor 11 via a mirror 9 and a lens 10. Data from the CCD sensor 11 is read by a clock of a CCD controller 12, and after the read picture data is compressed by a compression converter 13, the result is stored in a picture memory 17 via a picture mixer 16. The residual amount of the picture memory 17 is detected by a memory residual amount detecting circuit 14 and when the residual amount is swept out or reaches a prescribed value, a mark pattern from a picture pattern generator 15 is mixed with a picture data at the picture mixer 16 and the result is stored in the picture memory 17 and the stored picture data is transmitted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a facsimile machine, and more particularly to a facsimile machine having a memory for storing image data.

[Prior Art] In recent years, facsimile transmitting apparatuses that temporarily store read images in a memory and then transmit them have become popular for the purpose of shortening line occupation time or matching communication speed and reading speed. Such devices are equipped with an image memory large enough to store image data for several pages of standard-sized originals, but when transmitting high-density originals such as newspaper stock sections, the original size Even if it is standard, the image memory will overflow, so the image data of the document must be sent in parts. That is, the image data up to the middle of the document is transmitted as the image data of the first document, and the remaining image data is transmitted as the image data of the next document.

As a result, on the receiving side, one document is originally divided into a plurality of sheets and recorded, and if necessary, the recording sheets must be connected by adhesive or the like to reproduce the original form. However, depending on the document, the recorded image may be divided at an inappropriate portion due to a size mismatch with the recording paper, making it difficult to connect and reproduce the recording paper.

[Objective] The present invention has been made in view of the above points, and it is an object of the present invention to provide a facsimile device that can easily connect and reproduce recording paper on the receiving side when image data is transmitted in parts. With the goal.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

In the apparatus of the present invention, when it becomes necessary to perform divided transmission of image data, a transmission operation as shown in FIG. 1 is performed.

What is indicated by code 1 on the left side of FIG. 1 is image data rA.
BC...'' This is a high-rich document that exceeds the image storage memory capacity even if image compression is performed. It is assumed that this document l is scanned from the top to the bottom of the figure, and that the amount of image data from point P1 to point P2 corresponds to the capacity of the image storage memory.

Therefore, image data after point P2 on document 1 is transmitted as image data for the second sheet.

As a result, the recording result becomes as shown on the right side of FIG. That is, on the first recording paper 2, there are
Image data corresponding to 2 is recorded. Further, image data from points P2 to P3 of the original 1 is recorded on the second recording paper 3. Particularly in this case, three characters of the image information "rKLM" are divided and recorded on two sheets of recording paper.

In the apparatus of the present invention, a mark indicating that the image data has been divided and recorded, or furthermore, a mark indicating the position thereof, is recorded in this divided area. In other words, the first recording paper 2
A mark M indicating the dividing point is recorded at the final point P4 and/or at the leading point P5 of the second recording paper 3. As a result, when the operator on the receiving side wants to reproduce the original image, he only needs to align the marks and glue them together, which simplifies the operation.

Next, FIG. 2 shows in detail a block diagram of the configuration of a facsimile machine adopting the present invention.

As shown in FIG. 2, the original 1 is scanned while being transported by transport rollers 4. As shown in FIG.

The conveyance roller 4 is driven by a motor (not shown), and the rotational direction of this motor is controlled by a motor control circuit 6 in order to control the conveyance direction described above.

The motor control circuit 6 is composed of a driver circuit, etc.
It is controlled by a CPU (central processing unit) 21.

The CPU 21 controls the operation of the entire device in accordance with a predetermined program stored in a ROM (read only memory) or the like, similar to known devices.

On the other hand, the image of the original 1 is illuminated by a light source 7 composed of a fluorescent lamp or an LED, and the reflected light 8 is reflected by a mirror 9.
An image is formed on the CCD sensor 11 via an optical system consisting of a lens 10 and the like.

The CCD sensor 11 is a line-shaped photoelectric conversion element that reads image data for each l scanning line, and for each reading operation, the original is transported by one scanning line in the forward direction by the conveyance roller 4, and the image on the original l is sequentially transferred. be read.

Data reading from the CCD sensor 11 is performed by a CCD controller 12 in a known manner. The image data of the document 1 read out by the clock of the CCD controller 12 is compressed and converted by a compression converter 13 using various known methods.
The image is stored in the image memory 17 via the image mixer 16.

The remaining capacity of the image memory 17 is detected by the remaining memory capacity detection circuit 14.

If there is no remaining power or the remaining power has reached a predetermined value,
The image mixer 16 mixes the image pattern of the mark M illustrated in FIG. Send data.

The data in the stored image memory 17 is modulated by a modem 18 according to a predetermined method and transmitted to a line 20 via a known network control unit (NCU) 19.

The image mixer 16 described above writes the image data of the mark generated by the pattern generator 15 into a memory area corresponding to the position where the mark is to be recorded.

Further, the remaining memory amount detection circuit 14 can be configured from a decoder, for example, and in that case, the image memory 17
When a bit pattern of a predetermined address occurs on the address line of the image memory, it is assumed that the area up to that point has been consumed, and ``no remaining capacity'' or ``low remaining capacity'' may be detected. Image mixer 16 and remaining memory amount detection circuit 1
4 may be configured by software of the CPU 21.

Furthermore, the pattern generator 15 can be constructed using an element such as a character generator.

Next, the image transmission operation in the above configuration will be explained in detail.

FIG. 3 is a flowchart showing the control procedure of the CPU 21 in FIG. However, since the divided transmission operation itself is well known, detailed illustration thereof will be omitted here.

When the apparatus is started, first in step S2, the CPU 21 uses the motor control circuit 6 to transport the document 1 in the forward direction by l lines (scanning lines) by the transport roller 4, and then uses the CCD sensor 11 to capture an image of one line. Read data.

In step S3, it is determined whether or not reading of the original has been completed. This determination uses the output of a document detector (not shown) for detecting the end of the document or the output of the CCD sensor 11 to determine whether there is a document to be read. If the document has been completed, the process moves to step S3'', and if there is still a document, the process moves to step S6.

In step S6, it is determined whether there is any remaining capacity of the image memory. If there is no remaining capacity in the image memory, a division flag provided in a predetermined area such as the control memory is set in step S7, and the process proceeds to step 510; if there is remaining capacity, step S8
It is determined whether the division flag is set, that is, whether or not divisional transmission is to be performed.

If the division flag is not set, the process moves to step S11, and if there is a 5-division flag, the division flag is reset in step 38', and then the process moves to step S9. Check whether the line to be processed is the line corresponding to the beginning of the recording paper. Determine whether or not. If the processing line is the first line, proceed to step SlO; if it is not the first line, proceed to step 5.
11.

In step SIO, the image pattern of the mark M is read out from the pattern generator 15 and mixed with the read image data of the l line in the image mixer 16.

Thereafter, the stepper 311 stores one line of image data in the image memory 17.

In step S12, the state of the division flag is checked again.

If the split flag is set, step 313
If not, the process returns directly to step S2.

In step S13, it is determined whether a line connection has already been made. If the line power is controlled, the process moves to step S14; otherwise, the process moves to step 315.

In step S14, among the image data in the image memory 17, the data up to the front of the division mark are stored as S-gil and IQm.

On the other hand, in steps S3'' and S4'', steps S13 and S
The same operation as step 15 is performed to check whether the line is connected or not, and if the line is not connected, the line is connected and then the process moves to step S4. In step S4, the (remaining)
After transmitting the data, the line is disconnected in step S5, and communication is terminated. Therefore, sending a short manuscript is done in step S.
This is carried out in steps 2 to S5.

According to the above embodiment, when the image data of one document is divided into multiple parts and sent, a mark based on an image pattern indicating the division of the image is sent, and this mark is recorded at the beginning of the divided part of the recording paper. Therefore, this mark can be used as a guide when reproducing an image by gluing recording paper, making the work extremely easy. Although the above flowchart shows an example in which a mark is placed only at the beginning of the divided portion, the software may be changed so that a mark is placed at the end of the divided portion.

The above configuration can be implemented with only a few changes in hardware and software, so it is very simple and inexpensive. In the above embodiment, the transmitting device is provided with image pattern generation means for marks indicating the image data division positions. Although the pattern generator is provided in the receiving device, the image pattern of the mark may be read and recorded on the receiving device when a predetermined signal is transmitted from the transmitting device.

[Effect] As is clear from the above description, according to the present invention, when image data is divided due to an overflow of the image memory, a mark indicating that division processing has been performed or a division position of the image data is displayed on the recording paper. Since a configuration is adopted in which a predetermined mark indicating the facsimile is recorded, it is possible to provide an excellent facsimile apparatus in which the recording paper can be easily recycled on the receiving side.
