Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine which can use cut sheets as receiving recording sheets.

[0002]

2. Description of the Related Art In recent years, in the era of multimedia, high resolution, high speed transmission, halftone expression, etc. are required even in facsimile machines in which image information is remarkably used.
Therefore, the amount of data to be processed is extremely large.
Among them, as a method for recording the received facsimile information on recording paper, at present, generally, roll paper for performing thermal paper recording is widely spread, but it cannot be stored for a long time due to discoloration due to heat, Also, due to the reason that the size of the recording paper is different and the price of the output device such as the laser recording system and the inkjet recording system is reduced, a facsimile machine capable of recording plain paper using cut paper has been put into practical use. There is. In addition, a high-speed facsimile etc. having an image memory for temporarily storing and accumulating image data was developed in order to increase the reading speed of the original document and the high-speed processing of the encoding processing circuit or to match the data communication speed with the communication line. Has been done.

A conventional facsimile machine will be described below. FIG. 4 is a schematic block diagram showing the configuration of a receiving unit of a conventional facsimile apparatus. 301 is an input terminal for inputting received data, 302 is a storage memory unit for storing and storing the received data, 303 is a memory control unit for controlling the storage memory unit 302, 304 is a recording unit for storing the received data of the storage memory unit 302, which will be described later. A recording control unit that sends the image to the control unit 305 and controls the recording unit 305 is a printing unit that is a printing unit that can perform plain paper recording such as a laser recording method or an inkjet recording method.

The operation of the facsimile apparatus configured as described above will be described below. First, the image data to be transmitted is one line of image data sequentially read in the main scanning direction by the image reading device having a CCD sensor or the like provided in the facsimile device, and black and white binary image data. Is the storage memory unit 302
Is accumulated in This accumulated data is, for example, CCI.
The image is encoded by the MH (Modified Huffman) encoding method described in TT recommendation T4, and the image is compressed and transmitted. Further, generally, data transmitted by a facsimile machine transmits an RTC (return to control) signal as a page break. Next, when the facsimile apparatus enters the receiving state, the received data is stored in the storage memory unit 3 from the input terminal 301.
02 is input. Here, the storage control unit 303 controls the storage memory unit 302 to store received data line by line. Here, the RTC signal is received as a delimiter for each inner page of the received data. Next, when the reception is completed, the reception data controlled by the memory control unit 303 and accumulated in the accumulation memory unit 302 is sent to the recording unit 305 line by line by the recording control unit 304, and is sequentially recorded. When detecting the RTC signal, the recording control unit 304 performs a page break process and prints on the next recording sheet. Alternatively, if the length of the recording paper attached to the facsimile machine is reached before receiving the RTC signal, a page break process is performed when the length of the recording paper is exceeded, and the received data is recorded again on the next recording paper. It

[0005]

However, in the above-mentioned conventional configuration, since the length of the original sent from the sending side is not limited, when the image data sent from the sending side exceeds the page length, a page feed is performed. However, if no information is written in the portion beyond that, a blank sheet is printed on the next recording sheet, and there is a problem that the sheet is wasted. Further, at present, in a facsimile machine which has a high processing capability as well as a high speed image reading apparatus, a high communication speed, and a high encoding speed, a printing time becomes long due to a paper feed of a blank sheet and a high speed facsimile. However, there was a problem in that it was not possible to utilize the features of the above and lacked in operability.

The present invention solves the above-mentioned conventional problems. When a cut sheet is used as the recording sheet, a blank recording sheet is prevented from being output, and a facsimile having a high printing speed and excellent operability and reliability is provided. The purpose is to provide a device.

[0007]

In order to achieve this object, a facsimile apparatus according to a first aspect of the present invention is a facsimile apparatus capable of using cut sheets as recording sheets, and is a sub-recording sheet. A recording paper length setting unit that stores the total number of lines in the scanning direction, a line number counting unit that counts the number of lines of received data that has been transmitted, and a line number and recording paper length setting unit that is obtained by the line number counting unit. If the number of lines is greater than the total number of lines by the line number comparison unit that compares the size with the total number of lines recorded in, the lines of the received data that exceed the total number of lines are all white lines. If the result of the white line detection unit that determines whether or not the white line detection unit is all white lines,
The recording control unit controls so that the received data exceeding the total number of lines is not output to the recording unit.

A facsimile apparatus according to a second aspect of the present invention is the facsimile apparatus according to the first aspect, which includes a noise removal processing section for performing image processing such as noise removal, and when the number of lines of received data is larger than the total number of lines. The configuration is such that noise removal processing is performed on received data that exceeds the number of lines.

Here, by including a document size detection circuit including a photo interrupter and the like, the document size of the recording paper is detected, and the recording paper length setting unit is an automatic setting unit capable of automatically setting the number of lines by the recording paper. A line number adjustment unit that can be variably set within the recordable range of the recording paper is provided.
As a result, convenience can be improved, for example, A4 size can be received on B4 recording paper.
An image quality mode detection unit for detecting whether the image quality selection mode according to the setting of the operation panel is the standard mode or the fine mode is provided. This makes it possible to correct the total number of lines in the recording paper length setting unit.

[0010]

With this configuration, the number of lines of the received data is counted by the line number counting section, and the line number is compared by the maximum total number of lines that can be printed out in the sub-scanning direction of the recording sheet set in the recording sheet length setting section. It is possible to determine whether the number of lines of data received by the unit exceeds the total number of lines that can be printed out, and the white line detection unit determines whether the received data that exceeds the total number of lines are all white lines.
When the result of the white line detection unit is all white lines, the recording control unit controls not to output the received data which is the white data exceeding the total number of lines, so that the output of useless blank recording paper is prevented. be able to. As a result, the paper feeding time of the recording unit can be omitted, so that the printing speed can be increased and comfortable operability can be obtained. Further, by setting the longest total number of lines that can be printed out in the sub-scanning direction of the recording paper in the recording paper length setting section, it is possible to set and record the A4 size even when using the B4 recording paper, for example. Since the recording adjustment of A4 size can be performed on the recording paper of B4, the convenience can be improved. Furthermore, a noise removal processing unit that performs image processing such as noise removal is provided,
If at least the number of lines of the received data is larger than the total number of lines, noise removal processing can be performed on the received data that exceeds the total number of lines to remove black spots and the like existing in the received data due to dirt, etc. It is possible to prevent the output of clear blank recording paper.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A facsimile apparatus according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic block diagram showing the structure of a receiving section of a facsimile apparatus according to an embodiment of the present invention.
Reference numeral 301 is an input terminal, and 305 is a recording unit. They are,
Since it is similar to the conventional example, the same reference numerals are given and the description thereof is omitted. The difference from the conventional example is that the following configuration is provided. That is, in FIG. 1, 101 is a storage memory unit that stores received data and temporarily stores the received data during printing processing, 102 is a memory control unit that controls the storage memory unit 101, and 103 is currently installed. A recording paper length setting unit in which the total number of lines of the recording paper length is set, 104 is a line number counting unit that counts the number of lines of received data stored in the storage memory unit 101, and 105 is counted by the line number counting unit 104. The line number comparing unit that compares the number of lines of the received data with the recording paper length for one page set by the recording paper length setting unit 103, and 106 determines whether each line of the received data is all white data. The white line detecting unit 107 detects the white line detecting unit 106, and when the received data of the portion exceeding the total number of lines of the recording paper length is all white data, The received data exceeds the total number of lines of the recording sheet length portion is a recording control unit that performs control so as not to output to the recording unit 305. Further, a noise removal processing unit (not shown) for performing image processing such as noise removal is provided, and if at least the number of lines of the received data being printed is larger than the total number of lines, the received data exceeding the total number of lines is received. On the other hand, noise removal processing is performed to remove black spots and the like that are present due to dirt on the received data.

The operation of the facsimile apparatus configured as described above will be described with reference to FIG. FIG. 2 is a flow chart showing the processing of the received data of the facsimile apparatus according to the embodiment of the present invention, and FIG. 3 shows the processing when the received data of the facsimile apparatus according to the embodiment of the present invention exceeds the recording paper length. It is a flowchart. In FIG. 2 and FIG. 3, first, when the facsimile apparatus enters the state of receiving facsimile data, the received data is sequentially stored in the storage memory unit 101 from the input terminal 301 (step S1). Here, the storage memory unit 101 is controlled by the memory control unit 102, the received data is stored for each line in the main scanning direction, and is repeated until the reception is completed (step S2). In the present embodiment, it is assumed that the received data is coded by the MH coding method or the like and image-compressed. In addition, the received data is assumed to include an RTC (return to control) signal as a delimiter for each page.

Next, the facsimile machine performs a recording operation which is a printing process. Here, the total number of lines A, which is the recording paper length corresponding to the longest printable range in the sub-operation direction of the currently installed recording paper, is set in the recording paper length setting unit 103 (step S3). Next, substitute 0 for the number of lines N,
Initialization is performed (step S4). Next, the received data is taken out. First, the line number counting unit 104
Thus, the number of lines N from the start of recording the received data on each recording sheet is counted (step S5). Next, the received data stored in the storage memory unit 101 is sequentially taken out line by line as line data (step S6). The extracted line data is demodulated and sent to the recording unit 305 by the recording control unit 107 and recorded (step S7).
Here, it is confirmed whether or not all the received data have been completed (step S8). If all the received data is completed, the recording paper is output by paper feeding and the printing process is completed. If not, it is further confirmed whether or not there is an RTC signal indicating the end of one page which is the page end. Yes (step S9). If there is an RTC signal indicating the page end, the process returns to step S4, and recording of a page is newly started. In step S9, if there is no RTC signal, the line number comparing unit 105 compares the line number N of the received data with the total line number A corresponding to the recording sheet length set in the recording sheet length setting unit 103, and determines the number of lines. It is determined whether N exceeds the recording paper length A (step S10). If not exceeded, the process returns to step S5, and the line data of the received data is repeatedly recorded. However, in step S10, when the number N of lines of received data exceeds the recording paper length A, for example, when A4 recording paper is set on the receiving side, the received data with a length exceeding A4 size is sent. If so, the received data in the storage memory unit 101 is further extracted (step S11), and the white line detection unit 106 determines whether or not the line data for one line is all white data (step S1).
2). As a result, if the line data is all white, then it is determined whether all the received data have ended (step S14). Here, if all the received data has been completed, the printing process is completed. If not, next, it is confirmed whether or not there is an RTC signal which is the page end (step S15). If there is no RTC signal, the process returns to step 11 to sequentially fetch line data and repeatedly determine whether or not the line data is all white line data. At this time, the line data is not sent to the recording control unit 107 and remains in the storage memory unit 101. In step S12, if the line data is not white, the storage memory unit 101
At step S13, the received data is set again so that the received data can be extracted from the line data that exceeds the recording paper length A by one line (step S13). Next, when the RTC signal is detected in step S15, the process returns to step S4, and proceeds to the recording process for the next page. That is, the RTC that is the page end
When all the lines are all-white data when the determination is completed up to the signal, recording of the page is omitted. If not, line data is sequentially taken out from the storage memory unit 101 in which all the pages are temporarily stored and is recorded on the next recording paper. After that, in either case, the process moves to the next page process, all the received data are repeatedly read, and the process ends.

As described above, according to this embodiment, when the recording sheet is a cut sheet, the data sent from the transmitting side is longer than the receiving side recording sheet length and exceeds the recording sheet length. If no data is written in the part, if there is an all-white page in the data of the received data, the process ends without recording that page. As a result, it is possible to prevent useless blank sheets from being output in the facsimile machine on the receiving side.

[0016]

As described above, the present invention is a facsimile apparatus that can use cut sheets as recording sheets, and includes a recording sheet length setting unit that stores the total number of lines of the recording sheets in the sub-scanning direction. A line count unit that counts the number of lines of the received data that has been transmitted, and a line count comparison that compares the number of lines obtained by the line count unit with the total number of lines recorded in the recording paper length setting unit. If the number of lines is larger than the total number of lines by the line number comparison unit, the white line detection unit that determines whether all the lines of the received data that exceed the total number of lines are white lines, and the white line detection unit When the result is all white lines, a recording control unit that controls not to output the received data exceeding the total number of lines to the recording unit is provided, and thus it is possible to prevent the output of useless blank recording paper. Can, it is possible to realize a superior facsimile apparatus to resource conservation. Further, since the paper feeding time can be omitted, the printing speed can be increased, and the facsimile device having excellent operability can be realized.
