Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an image communication apparatus, and in particular, a plurality of roll-shaped recording papers are loaded, and the received original image is recorded using any one of the recording paper rolls. The present invention relates to an image communication apparatus having a recording paper cutting mode for cutting recording paper for each communication.

[Prior Art] Conventionally, there is known a facsimile apparatus having a plurality of sizes of recording paper and selecting the recording paper according to a communication procedure to perform recording. For example, there is a so-called double roll type facsimile apparatus which has two recording paper rolls having different widths and uses them selectively.

Even with this type of device, when using the binary communication procedure compliant with CCITT recommendation, the maximum width of roll paper that can be recorded is notified from the receiving side to the transmitting side by a DIS (digital identification) signal, etc., like other facsimile machines. The transmission side determines the transmission image size accordingly.

Since the image size actually used by the transmitting side is declared by a DCS (digital command) signal or the like, the receiving side determines the recording paper roll to be used according to the declared size.

On the other hand, in a facsimile machine, when roll-shaped recording paper is used, there is known a technique of cutting the recording paper into a predetermined size after recording. The cutting method is a one-page cutting method and a one-communication cutting method. It has been known. In the one-page cut method, the recording paper is cut into pages such as A4 and B4, and in the one-communication cut method, the recording paper is cut after each communication.

The one-page cutting method has an advantage that a troublesome recording paper cutting operation is not required in the subsequent filing work, while the one-communication cutting method has an advantage that recording paper received by a large number of communications is not confused. . Since these advantages cannot be obtained by the mutual cutting methods, it is desirable that either method can be selected by operating the switch.

[Problems to be solved by the invention] By the way, the declaration of the maximum width of the recording paper on the receiving side by the DIS signal is not limited to the pre-communication procedure, but is naturally performed during communication if there is a change in the communication mode such as an image size change. Be done.

In the conventional device, when the DIS signal is transmitted after the communication mode is changed, the maximum recording width that can be always declared is declared regardless of the switch setting of the recording paper cutting method of 1 page cut / 1 communication cut described above. There are the following problems when the communication cut method is set.

For example, in a receiver having a double roll of A4 / A3 size, according to the conventional method, the maximum recording width, that is, A3 is declared in the pre-communication procedure.

Here, if the first page of the sender's original is A4 and the second page is A3, the sender declares that it will send the A4 original by a DCS (digital command) signal, and accordingly, the receiver's A4 original is sent. Select the roll and record the received data of one page.

Next, when moving to the second page, since the image size is changed, following the transmission of the EOM signal from the transmitting side, the DIS and DCS signals are exchanged again for the mode change. According to the conventional method, the receiving side declares the maximum recording width, that is, A3 size, by the DIS signal, so the transmitting side declares A3 as the transmission image size by the DCS signal, and the A3 original of the second page is unchanged. I will send it.

In this case, the A4 roll used on the first page cannot record A3 size, so in order to prioritize the 1-communication cutting method, the reception is abandoned or the 1-communication cut is abandoned and the A4 roll is cut once. The only option was to switch to A3 roll.

[Means for Solving Problems] In order to solve the above problems, according to the present invention, a plurality of roll-shaped recording papers are loaded, and the recording of the original image received by using one of the recording paper rolls is performed. With doing 1
In the image communication apparatus having a recording paper cutting mode for cutting the recording paper for each communication, in the recording paper cutting mode for cutting the recording paper for each communication, the plurality of the plurality of recording papers are used in the pre-communication procedure prior to the reception of the first page. Declaring the maximum width of the recording paper roll as the maximum recording width, and performing the communication procedure to determine the communication mode again on the second and subsequent pages, declare the width of the recording paper roll used on the previous page as the maximum recording width. A configuration is provided in which means for controlling the communication procedure is provided.

[Operation] According to the above configuration, when the mode of cutting the recording paper for each communication is used, the recording paper roll used for receiving the first page can always be used to perform recording until the end of the communication. Therefore, the mode of cutting the recording paper for each communication can be prioritized.

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

FIG. 1 shows the construction of a double-roll automatic switching type facsimile apparatus as an embodiment of the present invention.

In the figure, reference numerals 1 to 6 are components similar to those of a known facsimile machine. In the figure, reference numeral 1 is a main control unit composed of a microprocessor or the like for controlling the operation of the entire apparatus.

Reference numeral 2 is a reading unit configured by an image sensor or the like for reading a document.

Reference numeral 3 is a communication control unit composed of a modem for modulating / demodulating a transmission / reception signal, an NCU (network control unit) for switching lines, holding a loop, and the like. The communication control unit 3 is connected to a communication line 6 such as a telephone line and a telephone 5 for line control or communication.

Reference numeral 4 is an operation / display unit for controlling the operation of the apparatus, which is composed of a keyboard such as a numeric keypad and a display such as an LCD and an LED.

Reference numerals 7a and 7b denote recording units such as a thermal printer, which perform recording using recording paper rolls # 1 and # 2, respectively. The recording paper rolls # 1 and # 2 made of thermal paper or the like may have the same size, but in the following description, it is assumed that the recording widths are different, such as A3 and A4.

The recording units 7a and 7b may be separate bodies as shown in the drawing, but the transport unit may be a separate body for each of the recording paper rolls # 1 and # 2, and the recording head and the like may be common to each roll. Good.

Which of the recording units 7a and 7b is used can be switched via the switch 8. This switch is composed of a multiplexer or the like and switches which recording unit is connected to the input / output unit of the main control unit 1. The setting of the switch 8 is controlled by the main controller 1.

When the switch 8 is connected to the recording unit 7a side, the main control unit 1 can detect the presence or absence of the recording paper of the recording paper roll # 1 and the width of the recording paper roll # 1. Recording can be performed on roll # 1.

When this switch is connected to the recording section 7b, the main control section 1 detects the presence or absence and the width of the recording sheet roll # 2, and performs recording on the recording sheet roll # 2 using the recording section 7b. be able to.

The structures of the recording units 7a and 7b are the same as those of the conventional apparatus, and the mechanism for detecting the presence / absence of recording paper and the width is composed of a photo sensor or the like.

The recorded recording paper recorded by the recording units 7a and 7b is cut by a cutter 10 driven by a solenoid or the like before being discharged to the outside of the apparatus.

The cutting method for cutting the recorded recording paper is 1
Either the page cut method or the one-communication cut method can be used. The switching of the recording paper cutting mode is performed by the cut mode switching switch 9. The cutting of the recording paper by the cutter 10 is controlled by the main controller 1 according to the setting of the cut mode changeover switch 9.

The main control unit 1 is provided with ROM 11 and ROM 12 for storing control programs and various variables. In particular
It is assumed that the RAM 12 stores at least which recording paper roll was used for recording the previous page.

In the above configuration, the binary procedure based on CCITT Recommendation T30 is used as the communication procedure. Therefore,
The width of the recording paper used is DI as shown in the previous example.
It is determined by the exchange of procedure signals such as S and DCS signals.

FIG. 2 is a flowchart of a recording width determination process to be declared by the DIS signal when the above facsimile apparatus receives an image. The illustrated routine is stored in the main control unit ROM11 together with the main program, and is used by branching from the main program when necessary.

According to CCITT Recommendation T30, the maximum width of receivable data is declared as the recording width in the facsimile information field of the DIS signal. However, whether or not reception is possible is defined by an independent bit. Therefore, when at least one roll is recordable, the recording paper width declared by the DIS signal can be determined by the procedure of FIG.

First, if the recording paper roll # 1 is not recordable in step S1, recording can be performed only by the recording paper roll # 2. Therefore, the process proceeds to step S8 and the width of the recording paper roll # 2 is declared as the maximum recording width. .

Similarly, if recording paper roll # 2 is not recordable in step S2, recording paper roll # 1 is recorded in step S6.
Declares the width of as the maximum recording width. The determination as to whether or not recording is possible in steps S1 and S2 is performed by detecting the presence or absence of recording paper with a photosensor or the like. At this time, the main control unit 1 controls the switch 8 to take in necessary information from the recording units 7a and 7b.

On the other hand, when both recording paper rolls # 1 and # 2 are recordable, the process proceeds to step S3, and it is determined which side the cut mode changeover switch 9 is connected to. Here, when the setting of the cut mode changeover switch 9 is the one-page cut mode, the process proceeds to step S7, and the larger one of the recording paper rolls # 1 and # 2 is declared as the maximum recording width.

In the 1-communication cut mode, the process proceeds to step S4, and it is determined whether the determined recording width declaration of the DIS signal relates to the first page (that is, whether it is a pre-procedure). If it is the first page, the process proceeds to step S7 similarly to the above, and the larger one of the recording paper rolls # 1 and # 2 is declared as the maximum recording width.

If the recording width declaration is made when the communication mode is changed on the second and subsequent pages, the process proceeds to step S5, and the contents of the RAM 12 are checked to determine which recording paper roll received the previous page. If the recording paper roll received on the first page is roll # 1, the process proceeds to step S6 and the maximum recording width is set to the width of recording paper roll # 1. If the recording paper roll used for the first page is roll # 2, the process proceeds to step S8 and the maximum recording width is set to the width of recording paper roll # 2.

As explained above, DI is set in the 1-page cut mode.
The same control as before is performed by always declaring the maximum recording width by the S signal.

On the other hand, in the 1-communication cut mode, the maximum recording width is declared by the recording paper roll loaded by the DIS signal in the pre-procedure prior to receiving the first page. Further, since the image size is changed on the second and subsequent pages, when performing the procedure again, the width of the roll used on the previous page is declared by the DIS signal. Therefore, if the 1-communication cut mode is set, the recording paper roll of the same size is continuously used from the first page. There is no need to interrupt communication.

If the sending device contains an original that is larger than the recording paper size that is consistently used in the middle of the page, the image of the original is reduced by the transmitting device in the same way as the conventional procedure. Sent through. That is, according to the present embodiment, the transmission side device does not need to perform any special processing, and may have the same configuration as the conventional one.

As described above, according to the present embodiment, the one-communication cut mode can be realized without any problem even in the double-roll automatic switching type facsimile apparatus.

In the above, in any case, if one communication cut method is set, the setting is given the highest priority, but
The priority may be changed as needed.

For example, the original width information of a new page is added to the EOM signal when changing the transmission mode, and then transmitted, and the receiver side records even in the 1-communication cut mode when the size of the recording paper needs to be replaced. Cut the paper, DIS
The maximum recording width may be declared by the signal.

[Effects of the Invention] As is apparent from the above, according to the present invention, a plurality of roll-shaped recording papers are loaded, the received original image is recorded by using one of the recording paper rolls, and the communication is performed for each communication. In an image communication apparatus having a recording paper cutting mode for cutting the recording paper, in the recording paper cutting mode for cutting the recording paper for each communication, the plurality of recording paper rolls are used during a pre-communication procedure prior to receiving the first page. When the communication procedure for declaring the maximum recording width of the above as the maximum recording width and determining the communication mode again in the second and subsequent pages is received, the width of the recording paper roll used on the previous page is declared as the maximum recording width. Since a configuration for controlling the recording paper is used, when the recording paper cutting mode is used for each communication, the recording paper roll used for receiving the first page is always used. Since the recording can be performed until the end of the communication, even in a device using a plurality of recording paper rolls, the mode of cutting the recording paper for each communication can be given priority without any problem.
