Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile machine, and more particularly to a multifunctional facsimile machine that includes a plurality of paper discharge trays and has the function of discharging paper to each of them.

(Prior Art) Facsimile communication is a form of image information transmission.
The original picture on the sending side is obtained as a hard copy on the receiving side, and facsimile machines have traditionally been standardized and grouped according to the transmission path (line) used, communication method, communication procedure, etc.

Among them, the 63rd and 64th machines employ a method of encoding and transmitting image data.

However, in recent years, as a digital line network, l5DN
(Integrated Digital Service Network) has been developed, and it is expected that it will provide not only images but also audio and various other information and communication services.

Such an integrated service network has a plurality of transmission channels, and can be used by connecting a large number of final terminals, such as the 63 and 64 terminals, to the -tree subscriber line. Moreover, the user can operate two or more of these at the same time. Furthermore, a facsimile machine having both 63 and 64 functions can also be connected to this l51)N.

(Problem to be solved by the invention) However, when used by connecting to such an IS1N, conventional facsimile machines of this type cannot receive and output G3 and 64 in real time, and There is a drawback that 63 outputs and 64 outputs on tray 2 are mixed. 6
If the same 11, 1j reception of 3-image reception and 64-image reception is not possible, in a system such as 15DN that sets multiple channels and performs multi-channel transmission, the image data is sent simultaneously from different sources. Since it is not possible to deal with such cases, the advantage of using such a line network is halved, and even if it has the G3 reception function and the (]4 reception function, the same It is unavoidable that the 63 reception output image and the G.1 reception output image will coexist on the ejected paper L-ray. It's inconvenient.

The present invention is based on the points mentioned above, and even when connected to a line network such as O'rf, it is possible to simultaneously receive image information on different channels. It is an object of the present invention to provide a facsimile device in which received image outputs are not mixed.

(Means and effects for solving the problem) The present invention provides -1
, In order to achieve the second objective, a facsimile device is provided, which is connected to a line network having a plurality of channels and is capable of receiving different facsimile information for each channel.
) In addition to providing a plurality of 111 paper I-rays corresponding to the I-note channels, a receiving system capable of simultaneous reception by different channels is provided, and the received image output of the different channels is sent to the plurality of paper ejection channels. Corresponding IJl on the back of the tray
l, fll; l-Reino\ By placing III paper separately, lh and I-registered separately '93 through the line network.
Even if transmissions from sources are made at the same time, this can be handled, and the υ1 paper is also sent separately.

(Example) Hereinafter, embodiments of the present invention will be described with reference to the drawings.

It is equipped with 2.

”-Note 15 I) N control 11+ 5 C, IS I)
The G3 communication unit 6 and the G4 communication unit 7 are connected to the ISL)N control unit 5, respectively.

The l5DN control unit 5 is a control unit that controls the D channel and B channel according to the protocol in l5DN. Further, the G3 communication unit 6 controls communication procedures and both data transfers according to the G3 protocol. Further, the G4 communication unit 4 controls communication procedures and image data transfer according to the G4 protocol.

Each communication unit 6, 7 is equipped with a modem and the like, and during transmission, the encoded output from the 11;1 coding unit 3 is sent to the G3 communication unit 6 or the G4 communication unit 7. After being supplied and subjected to predetermined processing such as modulation,
ili' control section 5, and sent to the I5DN access line via the I5I)N control section 5.

When the present facsimile apparatus receives image information from the other party's sending terminal, the l5I)N control section 5 controls the main control section 1.
In addition to controlling the notification of incoming calls to
1J The above channel control by the control section 5 includes control for selectively connecting a predetermined channel to the communication section. For example, if the received image data is G3 image data, l
The 5DN control section 5 controls the connection of the assigned B channel to the 63 communication section 6.

The image memory (I) 8 and the image memory (IJ) 9, which are individually connected to the G3 communication unit 6 and the G4 communication unit 7, include:
63 image data and 04 image data are transferred from each corresponding communication section. Each image memory manages input image data on a page-by-page basis and operates as a buffer, and can operate independently and in parallel.

The device of this embodiment connected to the 15DN access line is C;3.
/G4 communication function, 63-screen 1!11 reception and 64-screen (
When the signal reception occurs simultaneously, G3 and 64 are received at the same time. During simultaneous reception, while outputting one received image, that is, image data is read in page units from one of the two image memories 8.9 (for example, image memory (1) 8). When the paper is output to the corresponding paper output l/ray as described later, the received regional image data is stored in the other image memory (image memory (II)
9) is buffered.

One decoding section 10 is connected to each of the image memories 8 and 9, and the output of the decoding section 10 is further supplied to a single output section 11.

The decoding unit 10 decodes the encoded image data from the transmitting side into original image data. The decoding unit IO has an image (
The received G3 image data is selectively transferred from the image memory (■) 8 to the received G3 image data, and the received 64 image data from the image memory (■) 9 is selectively transferred in page units. Each piece of image data is decoded into original image data, and in this case, the decoding process is executed based on a decoding method instruction from the main control unit 1.

The single output unit I2 has a recording mechanism unit, and draws the original image on the sending side on recording paper using image data input in page units, that is, output image data from the decoding unit 11. . The recording machine (the 14 copies may be of any suitable type, such as a thermal recording method or a laser beam method, etc.).The recording paper obtained as a hard copy by the output section 12 is transferred to the paper output section 12.
The paper is ejected onto the paper ejection tray.

As described above, the paper ejection section 12 has a paper ejection tray for 63 and a paper ejection tray for 64, and receives received output images outputted from the output section 11 according to instructions from the main control section 1, that is, received images. The recorded recording paper (output paper) is sorted and ejected to each paper ejection tray. The distribution of paper to such paper ejection trays is determined by ejecting the paper, for example, by providing a mechanism for selectively setting the two paper ejection trays in the output section 12 equipped with the above-mentioned recording section. In the case of a configuration using such a mechanism, the main control section 1 controls to selectively switch this. That is, the l5DN mentioned above
Based on the incoming call notification from the control unit 5, the above-mentioned paper ejection tray cellar I is instructed and controlled in order to eject the paper separately to the corresponding υ1 paper tray depending on whether it is a G3 received image or a G4 received image. ”
Do 1.

As described above, the apparatus of this embodiment has two paper output trays, each of which has the function of storing 4111 sheets of paper separately, and the main control section 1 has a memo January 02, which is its program storage section. In addition, the received image data is managed at page 11, allowing simultaneous reception of G3 and 64 images, and paper ejection is also performed using G3 received images and 64 images.
A program is stored in advance to control the two output trays for the received image and the received image separately.
The main control unit 1 receives notifications of incoming G3 calls or 64 calls from the 15DN control unit 5, notifications of the results of executing each protocol procedure from the communication units 6 and 7, and notifications of page boundaries. Based on the above control program, processing is executed according to the control program, and upon reception, a control signal is sent to each of the controlled sections at a predetermined timing to switch the decoding process in the decoding section 10 described above, and to switch the decoding process in the paper discharge section I2. The allocation controls processing, etc.

The control contents of the main control unit l at the time of reception include the activation of these ports, specifically, the activation of each communication unit 6 and 7, and the I S l
) N fli'l Start accepting incoming calls to i31 section 5, image data reception for each image memory 8, 9 (;1 start instruction, page boundary instruction, and output instruction for one page of received G3 or G4 image data, output section 11 This also includes the activation of.

Below, the specific operations at the time of reception at 1°1\n are described in the case of G 31irii Ir & reception, 04 image 1 Sakae reception, and G3 image reception and 04:1lii f.
This section explains in detail what happens when two receptions occur at the same time.

FIG. 2 is an example of a flowchart showing a control procedure in the case of G3 image reception.

Now, suppose that image information is transmitted to this facsimile apparatus from the other party's sending side Gl via the 1sI)N connection line, the TSI)N control unit 5 notifies the main control unit 1 that 63 messages have arrived.

131,) When 63rd arrival is notified from the N control unit 5, (
In step 201), the main control unit 1 activates the G3 communication unit 6 and notifies the local ISDN 11IIJ control unit 5 that it has received an incoming call (step 202). This results in
The following specific reception processing is started.

That is, the T S I) N fli' control unit 5 firstly
The allocated 13 channels are connected to 63 communication section 6.

The G3 communication unit 6 performs a known procedure according to the G3 protocol and notifies the main control unit l of the result (step 20
3).

Next, the main control unit 1 instructs the image memory (I) 8 to start receiving image data (step 204).

As a result, from now on, from the 63 communication unit 6 to the image memory (I)
The 63 image data is transferred to the 1illii image memory (1) 8, and the image data transmitted via the 15DN access line is successively stored and accumulated in the 1illii image memory (1) 8 (step 205).

During this process, the 03 communication unit 6 monitors the page boundaries of the transmitted image, and when this is detected, the 63 communication unit 6
When the main control unit 1 is notified of the page boundary from , the main control unit 1 instructs the page boundary to the image (Sakae memory (I) 8)
Steps 206.207).

In this way, the received image data is managed on page 111 when stored and accumulated in the memory.

Further, for example, at this point, the main control unit l controls the paper discharge unit 12.
Instructs to output G3 image. As mentioned above, the paper ejection unit 12 is equipped with G3 and G4 paper ejection trays, and since it is currently receiving a G3 image, the G3 paper ejection tray is set to output r (formerly L) according to the above instructions. (step 208
). Next, the main control unit 1 activates the output unit 11 and instructs the decoding unit IO to perform a decoding method in step 209.
), and the reception G3 is sent to the image memory (I) 8.
Instructs to output one page of image data (step 21)
O).

When an instruction to output the l page is given, the received G3 image data is read from the image memory (■) 8, transferred from the image memory (■) 8 to the output unit 11 via one decoding unit 10, The received image information is recorded on recording paper in the output unit 11 (step 211).

After recording, the paper is ejected to the paper ejection tray by the paper ejection section 12, but as mentioned above, the G3 paper ejection tray is set in the paper ejection section 12, so the paper output from the output section 11 is
The paper is ejected to the paper ejection tray 63 by the paper ejection unit 12 (step 212).

If the transmitted image data is for multiple pages, the same process as above is executed (step 213), and the output paper obtained by recording the G3 received image is sent to the G3 paper output tray. become.

For G4 image reception, use the same procedure to
The paper is ejected to the L-ray. That is, in this case, regarding the communication section and image memory, the G4 communication section 7 and the image memory (II) 9 are used for Tono 1, respectively, and the decoding section 10 and output section 11 are shared and used for III. Furthermore, 1 no 1 paper part 12
Then, G4 river discharge paper I/ray is set.

In the case of receiving 4 images, the received data is managed in the middle of the page in the same manner as in the case of receiving 63 images in -11, and the recording paper obtained by recording 64 received images from output section 2 is used for G3. Separately from the paper for 64, the paper will be ejected to the "2".

Furthermore, even if G3 image reception and G4 image reception occur at the same time, as described above, by having two paper output trays and managing received image data on a page-by-page basis, G3 and (3
It is possible to receive 4 images at the same time, and in addition, G3 received images and 6
4 received images can be separately discharged to the paper discharge tray.

Since the device of this embodiment is connected to l5DN, depending on the case, 63 image information and 64 image information may be
In some cases, they may be transmitted simultaneously via a subscriber line,
In this way, even when 63-image one-image reception and 64-image reception occur simultaneously, the image memory (■) 8 and the image memory (II) 9 operate independently and in parallel, so each communication unit 6,
At step 7, image data at page iit is extracted from each image memory from the one of the received image information whose page boundaries have been detected as described above, and υ1 sheets are delivered to each corresponding paper discharge tray.

FIG. 3 is a flowchart showing an example of a control procedure in the case of such simultaneous reception, in which priority is given to the case of G3.

First, in step 301, it is determined whether simultaneous reception is possible, and if the answer is No, G3 or G4 reception processing is executed according to the processing shown in FIG. 2 as an example (step 302). .

If the answer to step 301 is Yes, the received image information is determined (step 3o3). The judgment in this step can be made based on the address data etc. added to each received data, and in this program example, two types, G3 and G4, are targeted, and G3 gJ
Therefore, in step 303, the received image is G3.
If the answer is Yes, transfer (storage, accumulation) processing to image memory (1) 8 for G3 is performed (
Step 304), if the answer is No, 64
If it is a received image, it is transferred to the image memory (■) 9 for G4 (step 3o5).

Thus, each image memory (+), (IJ) operates independently and in parallel.

Next, in step 306, as in the case of FIG. 2, the presence or absence of page boundary detection is monitored by the notification from each communication unit 6.7, and if the answer is No, steps 303 to 305 are performed. Repeatedly, if the answer is Yes, the page boundary detected is 63.
It is determined whether or not there is one for use (step 307).

If the answer to step 307 is Yes, that is, the page boundary detection notification was received earlier for the 63 received image, then step 308 and step 309 are performed, and step 3, which will be described later, is performed.
Proceed to step 12, and if the answer is No, that is, G3 for the G4 received image.
If a page boundary is detected before
10. Proceed to step 312 via 311.

According to the determination result in step 307, G3 and G
4, while output processing such as memory reading, decoding, recording, and paper ejection as described later is being performed, local received image data will be buffered in the corresponding image memory. That is, from step 307 to step 3
When proceeding to 08, flag F for determining whether it is G3 or 64
In addition to setting a to 1 shift 1, in this case, since the page boundary has been previously notified for 63 received image data, one page of image data is taken out from the image memory (■) 8 (step 309), Image memory (II) 9
Data reading is prohibited for G4 received image data, and if a page boundary is detected first and 0;
When the process proceeds from Step 307 to Step 310, the flag Fa is set to 1/O, and in this case, the process of reading one page of image data from the image memory (11) 9 is executed (Step 3). 311).

At this time, contrary to the above, reading of data from the image memory (■) 8 is prohibited, and the memory is buffered as described above.

Proceeding to step 312, it is determined whether the flag Fa is the value l, that is, whether it is the timing to perform the output processing of the G3 received image or the time to perform the output processing of the G4 received image. , if the answer is Yes, that is, to output the received image for G3, in step 313
A 3-way paper discharge tray is selected, and if the answer is No, that is, when a G4 received image is to be output, a 64-way paper discharge tray is selected (step 314).

In this way, the paper discharge tray is set in accordance with the image data read out in step 309 or 311.

Once the paper output tray has been set in step 313 or 314, the paper output tray is set in the same manner as in FIG.
The decoding and recording process of the successive data is executed for one page (step 315). In this case, instructions such as the decoding method are given in response to G3 or G4, as in the case of FIG. is performed (step 316)
. In this way, each υ1゛ is ejected to the paper tray in the middle of the page, and the transmitted image data is transferred to the tS.
If there are l pages, the same process as above is repeated (step 317).

In the case of simultaneous reception, as described above, the image data received while one received image is being output is buffered in the other image memory.
3-image reception and 64-image reception can be performed simultaneously, and even if only one decoding section and one output section are used, G3 reception images and 64 reception images can be output to separate paper output trays. .

Since G3/G4 reception can be performed as described in "U," it is easy to manage output images, and even when receiving them simultaneously, paper output tray 1
- There is no coexistence of ('3 output and G4 output, and since the reception is performed on multiple pages, there is no need to perform a tidying of the received output paper for each source after paper is ejected.)

FIG. 4 is a block diagram showing an embodiment of the pond of the present invention. In addition, in the same figure, 11°I?, which is the same as in FIG.
The component parts have the same sign.

In this embodiment, although the facsimile machine of the embodiment described above has a configuration using two image memories, image memory (1) 8 and image memory (1, 1) 9, j = J series. , is configured to use one image memory I3, and by performing time-division operation, it is possible to implement even one image memory as the used image memory.

Pond I'? ? Regarding the configuration, it is the same as in the embodiment mentioned above, and it is possible to receive and output G3 and 64 in real time, and in addition, the decoding unit, In addition to being possible with one output unit, this embodiment has the advantage that supplied image data can be managed on a page-by-page basis, and only one image memory is required to operate as a buffer.

Note that the present invention is not limited to the embodiments described above, and can be modified in various ways. For example, in each of the embodiments described above, the G3 received image and the 64 received image are ejected to separate paper ejection trays. Although 03 and 04 simultaneous reception is being performed, [8 G4 simultaneous reception or G3 simultaneous reception using channels 31 and 82 requires separate paper ejection trays corresponding to each channel to be ejected separately. This can be done by

In addition, regarding the paper output trays, each of these is set as a fixed tray, and the output route for recorded received paper is switched to output the paper to each fixed tray (selectively changes the flow of paper output).
You can do it like this. In this case, the distribution can be realized by adding a mechanism (11!) for changing the flow in the discharge path, so that it can be simplified in some ways.

Furthermore, the above embodiment is based on I S DNJIIG 3/G
Although the present invention has been explained using an example of a G3. G4
This function can also be applied to facsimiles using transmission/reception systems with different communication procedures other than the one based on the communication procedure described above.

(Effects of the Invention) As explained above, according to the present invention, the channel
A facsimile device that is connected to a line network with a set number of slots and is capable of receiving different facsimile information for each channel, [); In addition to providing a ray, a receiving system capable of simultaneous reception using channels as long as )° was developed.
Since the received image output of channel 4 is ejected separately to the corresponding Di paper 1 to ray of the plurality of paper ejection trays, one facsimile machine can output two It is possible to simultaneously receive the following image information from different sources, and it is suitable for use as a facsimile device connected to this kind of line network having multiple channels, and it is easy to manage output images. Even during simultaneous reception, images received from each channel will not be mixed up on the paper output tray.

Further, since only one output unit and the like is required as a facsimile machine, it can be manufactured at low cost, and has the advantage of being able to provide multiple functions at low cost.
