Description

  The present invention relates to a facsimile apparatus having a memory transmission function, and more particularly to a facsimile apparatus that processes and transmits information read from a document.

Conventionally, in a facsimile machine that reads an image and transmits the contents, if the read image is blank or a blank image is included in a plurality of input images, the transmission operation is performed as it is, The recipient received the blank image as it was.
Also, if the reading unit can read double-sided originals, double-sided / single-sided / blank paper originals are mixed, but until now the transmission operation has been performed as it is, and the recipient cannot reproduce the originals on both sides. Each facsimile machine was reproduced upside down.

  In response to these circumstances, for example, in Patent Document 1, a first image reading unit that reads information on the front side of a document, a second image reading unit that reads information on the back side of the document, and the first A document synthesizing unit that synthesizes the image data read by the image reading unit and the second image reading unit as one document data, and a storage unit that stores the document data synthesized by the document synthesizing unit, An electronic filing device having means for excluding blank page information from the information on the back side of the document when the document data is synthesized is disclosed. In Patent Document 2, external image input means for inputting image data, determination means for determining whether or not the input image data is a blank image, and whether to perform image output according to the determination result of the determination means A selection means for selecting the image and an external image output means for outputting an image based on the selection by the selection means. When the input image data is a blank image, the external output may not be performed. An image forming apparatus that is possible is disclosed. However, all of these are registered by deleting a blank page, but there is a problem that there is no control such as transmission, operator selection, and reverse side data conversion.

  Further, in Patent Document 3, the front side reading sensor 12 and the back side reading sensor 14 for reading images from both sides of a document are separated by a distance between the reading position A of the front side reading sensor 12 and the reading position B of the back side reading sensor 14. Separate by L. Then, in the single-sided reading mode, based on the image data read by the surface reading sensor 12 while the leading edge of the document moves from the reading position A to the reading position B, it is detected whether there is an image on the surface of the document. If an image is detected, the image reading by the back surface reading sensor 14 is stopped. Further, there is disclosed a double-sided reading device that allows an operator to check the set state when the front side of a document is white and an image is detected on the back side and when both sides of the document are blank. However, there is a problem that the contents are simply read on both sides and there is no data processing after reading.

  Further, in Patent Document 4, in a facsimile apparatus capable of double-sided reading and double-sided recording, the receiver has a means for notifying the transmitter of the presence / absence of the double-sided recording function and a desirable transmission method of backside information, Discloses a facsimile apparatus having means for notifying a receiver of whether or not double-sided reading is performed and a method of transmitting information on the back side. However, in the case of a two-sided original with a mixture of blank pages, the information on the front and back of the original may be related, and the selection can be easily set by the operator. There is a problem that it is only doing.

The facsimile apparatus of the present invention is further characterized in that when copying or transmitting, the display unit displays the number of pages to be copied or transmitted, the number of deleted pages, and the number of read pages. .

By the means for solving the above, in the facsimile apparatus of the present invention, when copying and transmitting both sides of a document by copying and transmitting, if the read document has a black rate less than a predetermined value, a blank page is copied or transmitted. Can be excluded.
Further, in the above-described reading unit, transmission of a blank page can be omitted when the receiving side does not have a double-sided printing function.
Furthermore, since the above-described reading unit transmits the data obtained by reading the reverse side upside down, the reception side can be prevented from receiving upside down.

The best mode for carrying out the present invention will be described below with reference to the drawings. Note that it is easy for a person skilled in the art to make other embodiments by changing or correcting the present invention within the scope of the claims, and these changes and modifications are included in the scope of the claims. The following description is an example of the best mode of the present invention, and does not limit the scope of the claims.
FIG. 1 is a schematic view showing an external configuration of a duplex scanning facsimile apparatus.
The facsimile apparatus 10 includes a document table 3 on which a document to be transmitted is placed, a document feeding unit 4 that conveys the document to a reading unit 5, a reading unit 5 that reads a document, and a document that has been read. And a paper discharge tray 7 that receives the transmitted original and forms an image, and a paper discharge tray 6 that discharges the image. Further, the liquid crystal display unit 9 displays various kinds of information such as transmission / reception destinations, and the user performs the main operation of the facsimile apparatus 10 with the operation unit 8 arranged in the vicinity thereof.
In the present invention, a storage device is provided in the facsimile apparatus 10, and data is stored in a storage medium detachable from the facsimile apparatus 10. As the storage medium, an optical recording medium is preferably used from the viewpoint of capacity and storage. The optical recording medium is capable of storing data of 10,000 sheets or more of A4 size paper even with a CD-R, and is fully compatible. However, in consideration of convenience, a rewritable type such as CD-RW, DVD + RW, or DVD-RW is preferable.

FIG. 2 is a block diagram for explaining the control in the facsimile apparatus of the present invention. The operation during reception / transmission will be described below.
When the facsimile apparatus 10 receives a facsimile via the modem 14 and the NCU 15, the data is temporarily stored in the memory 11 and stored in a storage medium 19 set in the storage apparatus. At this time, the data is converted and stored in a file format compatible with other digital devices, for example, TIF format so that the data can be reproduced and edited by other digital devices such as a personal computer. Further, when a file to be stored and stored in the storage medium 19 is created, the received time is stored and saved as the file creation time. Thereby, for example, “facsimile received from Mr. A one year ago” and the like can be easily searched and browsed anywhere, and the use of facsimile data can be expanded. Whether the printout is necessary can be determined by the user, and when the printout is performed, the writing unit 18 prints on the paper.

At the time of transmission, when a paper document is transmitted, the reading unit 17 reads the document, temporarily stores the data in the memory 11, and stores and saves the data in the storage medium 19 set in the storage device. At this time, similarly to the time of reception, the transmission time is stored and saved in a file format compatible with other digital devices.
Further, when the facsimile apparatus 10 has a one-touch dial function and information such as a transmission / reception destination name and a facsimile number is registered in the one-touch dial, the file name is automatically saved as the one-touch dial registered name and the serial number. This makes it easier to search for the other party during transmission.

  FIG. 3 is a diagram showing the situation of reading a double-sided document over time, and is a schematic diagram showing a paper path. In (a), a document set on a document table for reading a document is separated and conveyed by the separation unit in the document feeding unit 4. In (b), the surface of the conveyed document is read at a position of a reading sensor (for example, an image sensor) in the reading unit 5. Thereafter, as shown in (c), after the front side is read, the original is rotated once to read the back side. Next, as shown in (d), the sheet is conveyed from the reverse position to the conveyance roller, and is conveyed to the reading sensor position by the conveyance roller. At this time, as shown in (e), since the upper and lower upper sides of the front surface are rear ends, the rear surface is read from the rear end. Thereafter, as shown in (d), the paper is discharged and the second and subsequent originals are similarly read.

  FIG. 4 is a diagram illustrating data conversion in which the upper and lower sides of the data read on the back surface are exchanged. When there are n pieces of back side data in the main scanning direction and m pieces in the sub scanning direction, the nth data of the mth data is moved to the first of the first data. The (n−1) th data of the mth data is moved to the second of the first data. The same operation is repeated for all m-th data (n). Next, the nth data of the (m−1) th data is moved to the first of the second data. (M-1) The (n-1) th data of the second data is moved to the second of the second data. The same operation is repeated for all (m−1) th data (n). (M-2) Data is rearranged in the same manner for the data after the first. The rearranged data is stored in the storage medium 19.

  When copying and transmitting a document by reading the front and back surfaces of the document, image data of the read document is once stored in the storage medium 19 in the facsimile apparatus 10 from the reading unit 5 before copying or transmission. The stored data is converted into binary data and compressed, and the black rate (amount of black data) written on the document can be calculated from the data size of the image data. If the black ratio of the document read by the reading unit 5 is less than or equal to a predetermined value, if there is no data on the side, it is determined that the page is blank, and the page data is deleted. Repeat these operations on multiple scanned originals, and copy or send only pages with image information to be copied or sent, so that unnecessary blank pages are excluded from being copied or sent. Thus, processing is performed so that unnecessary copying and transmission are not performed.

Further, when the above-described reading unit 5 detects a blank page, it displays that there is a blank page on the display unit of the reading unit 5 and controls whether the blank page is to be copied or transmitted. This makes it possible for the operator to select whether or not to make a copy or transmission target for blank page processing. For example, “There was a blank page. Do you want to send a blank page?” Is displayed on the liquid crystal display unit 9 and the operator presses the “yes” and “no” buttons on the operation unit 8 to confirm the operator's will. It became possible to confirm.
Further, in the reading unit 5 described above, the read data is stored in the storage medium 19, and when the read data is transmitted, whether or not the receiving-side printing device supports double-sided printing is determined by a transmission communication protocol. Confirm that if you do not support double-sided printing, even if you send a blank page, it will only output the blank page wastefully. As a result, it is possible to prevent the receiving side from making a useless output and shorten the transmission time.

Further, in the reading unit 5 described above, data obtained by reading the front and back surfaces of a plurality of documents is stored in the storage medium 19 on the first front surface, back surface, second surface, back surface. . . And saved. Reading is performed by reading the front surface of the first sheet, reversing with the reverse roller, scanning the back surface of the first sheet, scanning the front surface of the second sheet, reversing with the reversing roller, and reading the back surface of the second sheet. . . A document set on the document table 3 is read. As described above, the upper surface of the first sheet is read upside down with respect to the reading of the first sheet. If this data is transmitted as it is, the back side is upside down compared to the front side. From the stored data, the back side data is rearranged by data conversion and stored in the storage medium 19.
By transmitting the data read on the front side and the data converted on the back side, the receiving side can receive the data with a constant vertical relation regardless of the front side or the back side.

In addition, in the above-described reading unit 5, whether the data read on the back side is upside down or transmitted as it is is transmitted to the liquid crystal display unit 9 of the facsimile apparatus 10 at the time of transmission. And by selecting “yes” “no” on the operation unit 8, it is possible to select whether or not to convert the read data.
Also, the reading unit 5 reads the front and back data, reverses the back data from the read data by data conversion, deletes the blank page, and starts the transmission operation.

Further, when copying or transmitting in the reading unit 5 described above, the number of read pages of the read data is counted and displayed. Similarly, the number of pages determined to be blank is counted and displayed on the liquid crystal display unit 9. Similarly, the number of pages to be transmitted is displayed on the liquid crystal display unit 9. For example,
"10 sheets read"
"3 blank sheets"
"Number of transmissions: 7"
By displaying, it is possible to clarify the number of transmissions to the operator. This may be printed as an image.

It is an example which shows the external appearance of a facsimile machine, (a) The perspective view from the front direction, (b) The perspective view from the back direction. It is a block diagram for demonstrating control in the facsimile apparatus of this invention. It is a block diagram for demonstrating control in the facsimile apparatus of this invention. It is the schematic which shows the paper path of the reading part which reads the back surface by rotating the original once after reading the front surface. It is a figure which shows conversion of the data which replaces the upper and lower sides of the data read on the back surface.
