Abstract

PURPOSE:To properly receive the sip of size A5 and to receive surely at least one picture of a transmitted original of the size A4, by providing an image signal storing means capable of storing the image signal of the size A4. CONSTITUTION:A received signal outputted from a network controller 1 is converted into a picture information before a modulation by a demodulating section 2 and the output signal of a demodulating section 2 is converted into an original picture signal by a decoding section 3. This signal PX is temporarily stored in a page memory 5 having the memory capacity of a size A4 initially through a control section 4. When the signal PX of one page of a transmitting original is stored, it is read by the control section 4 and recorded on a recording section 6 using the recording paper of a size A5. When the remaining amount of the recording paper of a paper feeding cassette is 0, and during a multi mode, the image transmission subsequent to the page is stopped and the storing contents of the memory 5 is held. Thereby, the proper receipt of the slip of the size A5 can be done and at least one of the transmitting original of the size A4 can be received and the capacity of the image memory device can be made minimum.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a facsimile machine that uses A5 size sheet-like recording paper as recording paper.

[Prior art] A commonly used facsimile machine is CCITT
It is configured to meet the standard specifications recommended by the International Telegraph and Telephone Advisory Committee (International Telegraph and Telephone Advisory Committee), and one of the specifications is that it must be able to receive at least one 4-size image. has been done.

On the other hand, facsimile machines used in Japan are often used mainly for transmitting slips, and the standard size of such slips is A5, so it is possible to directly send AS as a received image.
You may be required to obtain a certified copy.

Normally, the recording section of a facsimile machine uses a thermal head in which heating elements of dimensions corresponding to one pixel size are arranged in one row for the number of pixels for one line, and a roll-shaped recording head is used, in which only the heated part develops color. Thermal paper is used as recording paper, but in such recording units, the received paper that records and outputs the received image is cut to a slightly larger size than the transmitted original, and the timing of the cutting is Since the size varies depending on the transmitting device, there is an inconvenience that the sizes are not the same when files are created.

Therefore, it is possible to use an A5 size sheet of recording paper as the recording paper, but if there is only one sheet of recording paper left, a situation arises in which a 44 size image cannot be recorded. There was an inconvenience that the requirements could not be met. If a 44-size recording sheet is also installed in addition to the A5-size recording sheet, it will be possible to receive a 44-size transmitted document, but only if the user has 0 remaining 4-size recording sheets. However, similar inconveniences occur.

[Purpose] The present invention has been made in order to solve the above-mentioned disadvantages of the prior art, and it is possible to properly receive an A5 size slip and to reliably receive at least one image of a 44 size transmitted document. An object of the present invention is to provide a facsimile device that can minimize the capacity of a required image storage device.

[Structure] In order to achieve this object, the present invention is provided with an image signal storage means that can store image signals for A4 size, and the decoded image signal is temporarily stored in this image signal storage means, and the transmitted original is stored in the image signal storage means. When the storage for one sheet of is completed, feeding of the recording paper is started. and.

If the remaining amount of recording paper in the paper cassette reaches 0 at that time, image transmission following that page will be terminated, and
By retaining the stored contents of the image signal storage means, it is possible to receive images of at least 44-sized transmission originals.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a facsimile machine according to an embodiment of the present invention. Note that since the present invention particularly relates to a receiving system, only the receiving system will be explained.

In the figure, a network control device 1 interfaces a transmission line M (public telephone line in this case) and a facsimile machine, and a received signal output from the network control device 1 is applied to a demodulator 2 and modulated. The output signal of the demodulating unit 2 is converted into the previous image information by the decoding unit 3 and converted into the original image signal P.
It is converted to x.

This image signal Px is temporarily stored in a page memory 5 having a storage capacity for A4 size via the control unit 4.

When the image signal Px for one page of the transmission document is accumulated, it is read out by the control section 4 and transferred to the recording section 6.
recorded on recording paper. The control unit 4 also controls the network control bag w1.
, controls the respective operations of the demodulating section 2, the decoding section 3, the page memory 5, the recording section 6, and the backup power source 7 for holding the image signal Px recorded in the page memory 5, and executes a transmission control procedure. It is something.

The operation display unit 8 serves as a man-machine interface between the facsimile machine and the operator, and the operator's operation input signals are applied from the operation display unit 8 to the control unit 4, and the control unit 4 provides various signals to the operator. The message is displayed on the display of the operation display section 8.

The recording section 6 is a thermal recording device that uses an A5 size sheet of thermal vapor as recording paper, and as shown in FIG. A paper sensor 11 is arranged to detect when the paper runs out, and an output signal from this paper sensor 11 is applied to the control section 4. In the figure, the housing H is the housing of this facsimile machine, and the paper sensor 11 is a reflective optical sensor that uses infrared light so as not to be affected by ambient disturbance light.

Considering that a call has been made to this facsimile machine with the above configuration, first, the network control device 1 notifies the control unit 4 that the call has been made, and the control unit 4 then communicates with the calling station. After setting various functions such as paper size and transmission speed in the pre-procedure, the process moves to reception control.

In the reception control, the control section 4 determines whether there is recording paper from the output of the paper sensor 11, and if there is recording paper, activates the demodulation section 2 and the decoding section 3 to start the reception operation. . As a result, the image signal PX is stored in the page memory 5.

When the reception of one page of the transmitted original is finished and all the image signals Px are stored in the page memory 5, the control section 4 starts the operation of the recording section 6, and sequentially records the image signals px accumulated in the page memory 5. Transfer to Section 6.

Therefore, the recording section 6 feeds one sheet of recording paper from the paper cassette 10 and moves it to the standby position, and when the image signal Px is transferred, it moves the recording sheet one step and then outputs one line of image signal Px. are recorded sequentially and the received images are output.

At this time, the control unit 4 monitors the state of the output signal of the paper sensor 11 and determines whether the remaining amount of recording paper in the paper feed cassette 10 has reached zero. When the remaining capacity reaches 0, a predetermined procedure signal is transmitted to the other party's facsimile machine to terminate the image transmission at that point, and the image transmission is forcibly terminated.

Now, if we consider the case where the paper size set in the pre-transmission procedure is A5 size, in this case, the image signal px for one transmission document is stored in half of the area of the page memory 5, and when the storage is finished, the page Image signal Px from the first area of memory 5
is read out line by line.

If the remaining amount of recording paper at the time when the recording paper is fed to the recording section 6 is 1 or more and the multi-page mode is in effect, the process of reading out the image signal Px that has already been stored from the page memory 5 and the next reception In parallel, processing for sequentially accumulating the image signal Px from the empty area at the beginning of the page memory 5 is executed. In addition.

In this case, since the latter half of the page memory 5 is an empty area, the next image signal Px may be stored in that area.

Also, when the storage of image < ff number Px is finished and the recording paper is fed to the recording section 6, the remaining recording paper becomes 0, and if the multi-page mode is used, two more sheets of originals are left to be sent. image signals Px can be stored in the page memory 5, so image transmission can be forcibly terminated and the backup power source 7 can be
is activated to hold the stored contents of the page memory 5.

Then, the operation display unit 8 notifies the operator that the paper has been cut midway and that unrecorded image signals PX have been accumulated. As a result, when the operator replenishes the paper feed cassette 10 with recording paper and the output of the paper sensor 11 becomes a paper present state, the control section 4 operates the recording section 6 and the image stored in the page memory 5. Signal P
X is transferred to the recording section 6 and recorded. In this case, image transmission may be immediately interrupted when it is detected that the remaining amount of recording paper has become zero.

Next, if we consider the case where the paper size set in the pre-transmission procedure is A4 size, in this case, the image signal Px for one transmission document is accumulated in the entire area of the page memory 5, and when the accumulation is completed, the page The image signal Px is 1 from the first area of the memory 5.
It is read line by line.

If the remaining amount of recording paper at the time when the recording paper is fed to the recording section 6 is 1 or more and the multi-page mode is in effect, the process of reading out the image signal Px that has already been stored from the page memory 5 and the next reception A process of sequentially accumulating the image signals Px from the empty areas of the page memory 5 is executed in parallel.

In this case, when the transfer of the one-picture signal Px to the A5 size recording section 6 is completed, the recording section 6 is operated again, and the remaining picture signals px are sequentially transferred to the recording section 6.

In this way, the image of the A4-sized original to be sent is divided into two A4-sized documents.
It is divided and recorded on 5-size recording paper.

In addition, if the remaining amount of recording paper becomes 0 when the first sheet of recording paper is fed into the recording section 6, and if the multi-page mode is in effect, image transmission is forcibly terminated at that point, and the backup power supply is turned off. 7 to hold the stored contents of the page memory 5.

Then, the operation display unit 8 notifies the operator that the paper has been cut midway and that unrecorded image signals Px have been accumulated. Due to this.

When the operator refills the paper feed cassette 10 with recording paper and the output of the paper sensor 11 becomes a paper present state, the control section 4 operates the recording section 6 and also outputs the image signal PX stored in the page memory 5. It is transferred to the recording section 6 and recorded.

In this way, it is possible to receive at least one image of an A4 size original to be transmitted, and therefore it is possible to satisfy the specification of ``at least one A4 size image can be received'' in the CCITY recommendation.

By the way, in the embodiment described above, only A5 size sheet recording paper is used as the recording paper, but both A5 size sheet recording paper and A4 size sheet recording paper can be used. The present invention is also applicable to the following.

[Effects] As explained above, according to the present invention, an image signal storage means capable of storing image signals for A4 size is provided.

The decoded image signal is temporarily stored in this image signal storage means, and feeding of the recording paper is started when the storage for one sheet of the transmission document is completed. At that time, if the remaining amount of recording paper in the paper cassette becomes 0, image transmission following that page is aborted, and the stored contents of the 5-image signal storage means are retained, so that at least A4 size data can be transmitted. Since the image of the original document can be received, an advantage is obtained that an A5 size slip can be properly received and at least one image of an A4 size transmitted original document can be reliably received.
