Abstract

PURPOSE:To obtain an unmagnification picture without random reduction by divisionally outputting picture data to plural recording media by a recording part in the case of the size of recording media smaller than the size of picture data stored in a storage means. CONSTITUTION:In the case of picture reception, a maximum size of recording media which can be set to a recording part 6 is declared as the recording medium size of an equipment itself against the transmission side to receive pictures, and received picture data is stored in the storage means (a picture memory 4). In the case of recording of stored reception picture data, picture data is divisionally outputted to plural recording media by the recording part 6 when the size of recording mediums set to the recording part 6 is smaller than the miximum size. Consequently, picture data is divisionally outputted without reduction in the case of agency reception even if recording media whose size is smaller than that of reception pictures are set at the time of recording output. Thus, the degradation in picture quality is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image communication device, and particularly to an image communication device having a recording section using recording media of multiple sizes and a storage means for storing received image data. .

[Prior Art] In image communication devices such as facsimile machines, A4 size is set as a standard document and recording paper size. However, in reality, devices that can use larger-sized originals and recording paper, such as B4-sized documents, are also being manufactured. Therefore, when the transmitted original is B4 and the received recording paper size is A4, a technique is also used in which the receiving side reduces and records the image.

On the other hand, a facsimile device or the like is provided with a memory for storing received image data, and even when no recording paper is loaded in the recording section of the device, reception is performed and the received image data is stored in the image memory. Devices having a so-called proxy reception function are known. In such a device, if the recording section of the device is capable of loading recording paper of multiple sizes such as A4 or B4, when performing proxy reception, which size of recording paper is used during recording? Since it is uncertain whether the recording paper width will be the smallest size for the transmitter, for example, in the case of B4 and A4,
Devices that declare four sizes are known.

[Problems to be Solved by the Invention] In the device described above, if an 84-width document is used on the sending side, the image data is converted to A4-sized paper on the sending side by declaring A4-sized recording paper. Because it will be reduced,
There is a problem in that even if B4 size recording paper is loaded during recording, it is not possible to obtain a B4 size received image at the same size. If the characters on the document are particularly small, reducing the size may make it difficult to read.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a recording section capable of mounting recording media of a plurality of sizes, and a storage means for storing received image data. In an image communication device, when performing image reception, the sending side declares the largest size storage medium that can be attached to the recording unit as its own recording medium size, receives the image, and stores the received image data in the storage unit. and when recording the stored received image data, if the size of the recording medium loaded in the recording section is smaller than the size of the image data stored in the storage means, the image data is stored in a plurality of A configuration was adopted in which the output is divided into recording media.

[Function] According to the above configuration, even if the recording medium of the recording unit is smaller than the size of the transmitted original image, the image is not automatically reduced, and an image of the same size can be obtained.

[Example] The present invention will be described in detail below based on an example shown in one drawing.

Figure 1 shows the configuration of a facsimile machine as an example of an image communication device employing the present invention.The configuration shown in the figure is a control system in which each part necessary for operation is configured from a microprocessor, etc., as in a conventional facsimile machine. It is controlled by the department.

In the figure, the symbol l indicates NCU (network control unit)
A modem 2 is connected to the NCUI, which controls connection of a predetermined communication line NW such as a telephone line and maintains a loop. - The modem 2 performs modulation and demodulation operations based on a modulation and demodulation method based on CCITT recommendations, and has the same configuration as publicly known. Input/output signals of the modem 2 are connected to an address and data bus of a control section 7 composed of a microprocessor or the like.

The following members are connected to these buses.

Reference numeral 4 denotes a memory for storing received images or original image data to be transmitted, and is composed of a RAM or the like.

The decoding unit 3 converts image data of a predetermined encoding method such as the MH or MR method into black and white binary image data.

The line memories 5a and 5b store image data one line at a time during the recording/outputting operation described in t1. The line memories 5a and 5b are composed of the same RAM as the image memory 4. Image data to be recorded alternately is read line by line into these line memories 5a and 5b as in the normal case.

The recording unit 6 records the received black and white image data in dots using a dot printer such as a thermal printer. It is assumed that two types of recording paper, B4 and A4, can be loaded into the recording section 6.

The recording section 6 is provided with a sensor 8 including a photo sensor or the like that detects whether recording paper is loaded, and a sensor 9 that detects the width of the loaded recording paper. The outputs of these sensors 8, 9 are connected to the aforementioned bus.

The control section 7 controls the operations of each section described above according to a program stored in the ROM 7a, and causes communication operations to be performed.

FIG. 2 shows the flow of the control program stored in the ROM 7a.

The reception operation in the configuration of FIG. 1 will be explained below with reference to FIG.

In step Sl in FIG. 2, by checking the output of the recording paper sensor 8, it is determined whether recording paper is loaded in the recording section 6. If recording paper is loaded, the process moves to step 514, and a normal receiving operation is performed in which the received image data is sequentially recorded.

On the other hand, if no recording paper is loaded in the recording section 6, the proxy reception processing from step S2 onwards is performed, that is, a pre-communication procedure based on a predetermined method is performed in step S2.

For example, in the G3 facsimile system, various communication conditions are set by exchanging initial identification signals, and the communication speed is determined by training. In the 03 procedure, a DIS (digital identification) signal is sent to the sending side to declare the conditions on the receiving side. In this case, the maximum recording paper width is set to S4, and this 34 width is declared to the sending side. At the same time, the size of the image to be received is memorized by checking the procedure signal on the transmitting side.

In the following step S3, an image signal is received from the transmitting side. The received image signals are decoded by the decoding section 3 and sequentially stored in the one-image memory 4. However, in order to save the capacity of the image memory, the encoded data may be stored as is and decoded during recording.

When all the image signals are received, a predetermined post-communication procedure is performed in step S4, and the process moves to step S5. Step S5
Now, it is determined whether all reception has been completed. If there is a zero-order document to be received, the process returns to step S2 and the above process is repeated.

If step S5 is affirmative, move to step S6,
By checking the output of the recording paper sensor 8, it is determined whether recording paper is loaded in the recording section 6. If the recording paper is not loaded, the process moves to step S7, and it is determined whether or not there is an incoming call.If there is an incoming call, the process returns to step S2, and if there is no incoming call, the process repeats the receiving operation, then the process goes to step S6. return.

When the recording paper is loaded into the recording section 6, the loop of steps S6 and S7 is exited, and the process moves to step S8.

In step S8, the size of the loaded recording paper is detected by the sensor 9.
In the case of this embodiment, the recording paper size that can be loaded is S4. There are two types of A4 paper, and if the recording paper is S4, the process moves to step 310, and if it is A4, the process moves to step S9.

In step SIO, the loaded recording paper is S4, and equal output can be performed no matter what kind of image data is stored in the image memory 4. Therefore, one page of the received image data is recorded and outputted by the recording unit 6. let When the recording output of one page is completed, the process moves to step S13.

On the other hand, in step S9, it is checked whether the image size stored in the image memory 4 is S4 or A4. If the size of the received image data is S4, the process moves to step Sll, and if it is A4, the process moves to step 510. When moving from step S9 to step SlO, an A4 original image is recorded on A4 recording paper.

When proceeding to step 311, if the recording paper size is A
This is a case where the image data received in step 4 is S4. In this case, in this embodiment, the image of one page is divided into halves and output without reducing the image.

Here, the image data is divided into left and right parts and recorded over two pages.

That is, in step S11, the left half of the image in S4 is recorded and output, and in the subsequent step S12, the right half is recorded and output. The process of extracting only the left half or only the right half can be performed by manipulating the read address of the image memory 4. When performing recording output, the line memories 5a and 5b
are used alternately.

When Steps SlO to Step 312 are completed, the process moves to Step 513, and it is determined whether or not the previous page of image data stored in the image memory 4 has been output. If the output of the previous page has not been completed, the process returns to step S8 and the above operation is repeated.

According to the above configuration, when performing proxy reception, the image is not reduced in size but divided into a plurality of pages and recorded and output, so there is no problem that the image data becomes illegible.・Of course, the effect of proxy reception itself is not impaired, in that even if recording paper is not loaded, there is no chance of reception being missed.

In the above configuration, if the received image is larger than the loaded recording paper, split output is automatically selected, but what is the largest size of the received image data stored in the memory? It is also possible to display the presence of the image using a display or the like so that the operator can select an appropriate recording paper size according to the image size.

Also, when performing proxy reception, the recording paper size declared to the sending side may be the most recently loaded recording paper size instead of the largest possible size. If the received and stored image data is larger than the recording paper, it may be possible to perform divided output.

Furthermore, it may be possible to select whether to perform one-divided output or to reduce and output as before.

Furthermore, in the above example, the recording paper size is B4. Although two A4 sizes are illustrated, the same technique can be applied to devices using more sizes than this. It is also possible to use materials other than paper as the recording medium. It is also possible to declare the maximum width (A3) to be communicated, rather than the maximum width that can be stored.For example, even with an A4 receiver, it is possible to receive at the same size as A3.

[Effects of the Invention] As is clear from the above description, according to the present invention, an image communication system having a recording section capable of mounting recording media of a plurality of sizes and a storage means for storing received/received image data. When the device receives an image, the sending side declares the largest size recording medium that can be attached to the recording unit as its own recording medium size, receives the image, and stores the received image data in the storage means. In addition, when recording the stored received image data, if the size of the recording medium loaded in the recording unit is smaller than the maximum size, a configuration is adopted in which the recording unit divides and outputs one image data to a plurality of recording media. Therefore, when performing proxy reception, even if a recording medium with a size smaller than the received image is installed at the time of recording output, the image data is divided into multiple parts and output without performing reduction output. This has the excellent effect of preventing deterioration of image quality.
