Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a facsimile transmitter,
In particular, it relates to a document storage type facsimile transmitter.

[0002]

2. Description of the Related Art Conventionally, in this type of facsimile transmitter, an original reading section 1 for reading characters on an original as shown in FIG.
1, a code conversion unit 12 that performs an encoding process, a modem 13 that performs modulation, and a line control unit 14 that controls a communication line.

Such a conventional facsimile transmitter is
No function is provided to detect the upside down of the original.

[0004]

Since the conventional facsimile transmitter does not have the function of detecting the upside down of the original,
When the orientation of the transmitted original document is not uniform, some of the original documents are transmitted with the irregular orientation. For this reason, when filing a received document, the positions of the display of the senders are not uniform and it is not suitable to save.

An object of the present invention is to provide a facsimile transmitter having a function of detecting the upside down of a document.

[0006]

[Means for Solving the Problems] To achieve the above object
In addition, the present invention converts the content of an original into an image signal and converts the image signal into the original.
The document reading unit that outputs to the storage unit and document margin detection unit
Each time the main scanning of the original is performed, the left and right edges of the original are
The white image signal is detected as a margin and the
Output the count value of the white image signal to the document margin recording area.
The draft margin detector and the count value of the white image signal have already been read.
The count value of the white image signal of the scanned original and compare
If the size values are different, it is considered
None Document margin comparison section that outputs to the main control section, and if necessary
A main control unit that gives an alarm display instruction to the display unit,
Upside-down original only Only the original is stored based on the image signal data in the original accumulation section.
A document reversing unit that reverses the background to output an image signal is also provided.
It is.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

The facsimile transmitter of this embodiment has a document reading unit 1 for reading characters on a document, a storage unit 2 for storing the read document, a main control unit 5, and a white image signal for the left and right margins of the document. A document margin detection unit 4 for detecting as a count value, a document margin recording unit 6 for recording a white image signal as a count value, a document margin comparison unit 7 for comparing the white image signals to detect upside down, Document reversing unit 3 for reversing upside down
And a display unit 8.

Next, the operation of this embodiment will be described.

The document reading unit 1 converts the content of the document into an image signal and outputs the content of the document to the document storage unit 2 and the document margin detection unit 4. The document margin detection unit 4 detects white image signals at the left and right ends of the document as a margin each time the main scanning of the read document is performed, and the count value of the white image signals in the main scanning of all one sheet is used as the document margin recording unit 6 Notify to. The same process is performed for the second and subsequent documents, and the count value is the document margin comparison unit 7
At, the value of the document already read is compared. At this time, if the magnitude relationship between the left and right count values is different, it is regarded as an upside down original and the main controller 5 is notified.
The main control unit 5 instructs the display unit 8 to display an alarm if necessary. Further, only the upside-down inverted document is inverted to the original inversion unit 3 based on the image signal data of the original accumulation unit 2 to output an image signal.

FIG. 2 shows a concrete example of a document. The operation will be described in more detail with reference to FIG.

In the document margin detecting section 4, every time the main scanning is performed on the first document to be read, the first continuous white image signal and the last continuous white image signal are respectively left end margin and right end margin. Is detected as. The document margin recording section 6 counts the white image signals of the margins for each main scan. Also, using the method of averaging the count values within a certain range, or the method of searching for a value with a high frequency,
The summed result is set as the left margin a and the right margin b as the representative value of the first sheet.

Similar processing is performed on the second and subsequent originals to obtain a left margin c and a right margin d as representative values of the second original. Therefore, the document margin comparison unit 7 compares the value with the value of the first document. When c> d when a> b or c> d when a <b, the second original is regarded as an upside down original, and the original accumulation unit 2 determines the original based on the image data for each sub-scan. Swap the read start data and the final data.
Also, when the top and bottom of the original are inverted, the left margin of the second original is replaced with d and the right margin is replaced with c. Similar processing is performed on the third and subsequent sheets, and the count value is compared with the value on the previous page to determine the orientation of the document.

[0015]

As described above, the facsimile transmitter according to the present invention is provided with a function for detecting the left and right margins of the document contents one by one in the transmission of a plurality of documents, and when there is an upside down document. It has a configuration to prevent transmission. Therefore, in the case of a standard document in which the formats are uniformized by the use of a word processor, the manuscripts are received in a misaligned form, and the effect of reducing the time and effort in checking the manuscripts can be obtained.

Further, since the original transmitting side has a function of making the vertical direction of the original uniform, E on the receiving side
When using an electronic filing system such as WS to store image data in memory, not only is it easy to confirm on the display, but there is no need to provide a reversing function in the filing system, and document management is possible. The effect that it becomes easy is obtained.

Claims (1)

(57) [Claims] 1. A document reading unit for converting the contents of a document into an image signal and outputting the image signal to a document storage unit and a document margin detection unit, and a white image signal at the left and right ends of the document each time main scanning of the read document is performed. As the margin and outputs the count value of the white image signal in the main scanning of all the sheets to the document margin recording unit, and the count value of the white image signal counts the white image signal of the already read document. If the magnitudes of the left and right count values are different from each other compared with the value, it is regarded as an upside down original and the original margin comparison section that outputs to the main control section and the main control that issues an alarm display instruction to the display section if necessary And a document reversing unit for reversing the top and bottom based on the image signal data of the document accumulating unit to output the image signal only.
