Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a facsimile machine such as an Internet facsimile machine, and to a transmission method for transmitting images scanned by the facsimile machine.  
           [0003]    2. Description of the Related Art  
           [0004]    The Internet facsimile machine can transmit and receive Internet facsimiles using an electronic mail format. The Internet facsimile machine can also transmit or receive G3 facsimiles. The Internet facsimile machine scans original images, and transmits the scanned images as G3 facsimile data or the like, or as an attached file of an electronic mail. In such a facsimile machine, when scanning and transmitting the original image, if a paper width in a first scanned direction is the width of the short side of a piece of A4 paper, the facsimile machine is generally set to rotate the paper width by 90 degrees at transmission, and to transmit the original document as a landscape original which has a width of A3 sized paper, and which the image is longer widthwise than lengthwise.  
         SUMMARY OF THE INVENTION  
         [0005]    An advantage of the present invention is to reduce the communication time for a facsimile transmission, and to transmit images in easily viewable form for an electronic mail transmission.  
           [0006]    A facsimile machine of the present invention includes a facsimile communication unit, and an Internet facsimile communication unit. In addition, the facsimile machine includes a setting unit which sets to transmit a scanned image by rotating the image by 90 degrees. When there is a setting set by the setting unit, the facsimile communication unit transmits the scanned image by rotating the image by 90 degrees. In addition, the Internet facsimile communication unit transmits the scanned image without rotating the image by 90 degrees regardless of the setting. When the short side of the scanned original is in a first scan direction, it is preferable for the facsimile communication unit to rotate the scanned image by 90 degrees.  
           [0007]    A transmission method of the scanned image of the present invention is used in the facsimile machine which includes an image scanning unit, a facsimile communication unit, and an Internet facsimile communication unit. The transmission method includes accepting a setting to transmit the scanned image by rotating the image by 90 degrees. In addition, the transmission method includes transmitting the scanned image by rotating the image by 90 degrees in case of the facsimile transmission and when the short side of the scanned original is in the first scan direction. The transmission method includes transmitting the scanned image without rotating the image regardless of the setting of the Internet facsimile transmission.  
           [0008]    According to the present invention, even when the setting of the facsimile machine is to transmit facsimile data by rotating the facsimile data by 90 degrees, in the case of the transmission using the electronic mail format, the scanned image can be transmitted using the same format without being rotated. Therefore, in the case of the facsimile, a communication time and a communication expense can be saved. In addition, in the case of the electronic mail, the received data is easily viewable and convenient for a recipient. Moreover, when the paper width in the first scan direction is the short side, by rotating the facsimile data 90 degrees at the facsimile transmission, an output side can output the data from a long side of the output paper. As a result, the recipient can receive and output the data within a short period of time, and it is convenient for the recipient.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0014]    [0014]FIG. 1 through FIG. 5 illustrate an embodiment of the present invention. FIG. 1 illustrates an environment where an Internet facsimile machine  1  of the embodiment is used. Reference number  2  is a Local Area Network (LAN), and  3  is a mail server. In the drawing, the mail server  3  is shown as a separate machine from the Internet facsimile machine  1 . However, the Internet facsimile machine  1  can serve as the mail server  3 . Reference numbers  4  through  6  are communication terminals such as personal computers. Specifically, the communication terminals are a communication terminal of an administrator of the LAN  2 , or the communication terminal of a general user.  
         [0015]    The Internet facsimile machine  1  is connected to a G3 facsimile machine  8  via a public switched telephone network or the like. In addition, the Internet facsimile machine  1  is connected to the Internet  11  via a router  10 . The G3 facsimile machine  8  is an example of a conventional facsimile machine, and can be a G4 facsimile machine or the like. A communication terminal  12  is the communication terminal which is connected to the Internet  11 , and which is a destination of a transmission from the Internet facsimile machine  1 . As described above, the Internet facsimile machine  1  carries out a transmission and a reception of the Internet facsimile by using an electronic mail. In addition, the Internet facsimile machine  1  is connected to the G3 facsimile machine or the like via the public switched telephone network.  
         [0016]    [0016]FIG. 2 shows a configuration of the Internet facsimile machine  1 . In the drawing, reference number  20  is a main control unit,  22  is a network control unit (NCU), and  24  is a modem. The NCU  22  establishes a connection with the public switched telephone network or the like, and the modem  24  carries out a communication for the facsimile transmission and reception. An image memory  26  stores facsimile data or the like as image data. A Random Access Memory (RAM)  28  stores data or the like in a working state. A Read Only Memory (ROM)  30  stores control program or the like.  
         [0017]    A display unit  32  carries out display to the user by a Light Emitting Diode (LED), a Liquid Crystal Display (LCD) or the like. From an operation unit  34 , the user inputs a destination address or the like such as an electronic mail address or a facsimile number from a keyboard or the like. In addition, from the operation unit  34 , the user carries out an instruction for operation by a touch panel on the LCD. A rotational transmission setting unit  36  is a unit for setting to carry out the facsimile transmission by rotating the original image by 90 degrees from the touch panel or the like on the LCD. Normally, the 90 degree rotation and the transmission of the scanned original is set to ON. A scanning unit  38  scans the original image and reads image data. A paper size detecting unit  40  detects the paper size when reading the original image. A printing unit  42  prints the received image or the image read by the scanning unit  38  onto a recording paper.  
         [0018]    Reference number  44  is a LAN interface, and the Internet facsimile communication is carried out under an electronic mail format or the like by using the LAN interface  44 . The Internet facsimile machine  1  is connected to the personal computers  4 ˜ 6  of FIG. 1 or various terminals  46  or the like via the LAN  2 . The Internet facsimile machine  1  also functions as a network scanner or a network printer. For this reason, the Internet facsimile machine  1  works as a facsimile machine or a copy machine, and also functions as a network printer or a network scanner.  
         [0019]    [0019]FIG. 3 shows an example of the scanning of an original image at the Internet facsimile machine  1 , and transmitting the image when carrying out the facsimile transmission. For example, the G3 facsimile machine  8  of FIG. 1 is a receiving device. The rotation of the scanned image is set at the Internet facsimile machine  1 . At scanning, when the short side of the A4 sized paper on a platen glass  50  is in the first scan direction, the direction of the paper is rotated by 90 degrees when outputting. Then, the original is transmitted as a landscape image which the first scan direction is the short side of A3 sized paper and the second scan direction is the short side of A4 sized paper, and the receiving device outputs the image as a landscape image having a size of A4 sized paper. When the paper of the scanned original is smaller than A4 sized paper, for example, when the scanned original is on A5 sized paper, the scanned original can be rotated 90 degrees, and can be transmitted as an image having a width of that of a piece of A4 sized paper in the first scan direction, and the receiving device can output the received image as an image having a size of A5 sized paper. When the scanned original is B5 sized paper, the scanned original image can be rotated by 90 degrees, and can be transmitted as an image of B4 width in the first scan direction, and the receiving device can output the received image as an image having a size of B5 sized paper. Further, in the case of the image being on B4 or A3 sized paper, even when the rotational transmission is set, the image is not rotated and transmitted in the scanned direction.  
         [0020]    [0020]FIG. 4 shows an example of scanning of the original image at the Internet facsimile machine  1 , and outputting the image at a receiving device when transmitting the scanned image by an electronic mail. The receiving device is, for example, the communication terminal  12  which is connected to the Internet  11  in FIG. 1. When scanning the original document, the A4 sized document is placed on the platen glass  50  such that the short side faces the first scan direction. Even in the case the rotational transmission of the scanned image is set, when transmitting the image data under the electronic mail format, the Internet facsimile machine  1  does not execute a rotational processing of the scanned image, and transmits the scanned image by applying a header to an electronic mail. The recipient can display the image data of the received electronic mail on the display or the like, or can print out the image data. At this time, the original image is not rotated, and the image data facing the same direction as the original document can be obtained.  
         [0021]    An operation of the embodiment will be described with reference to FIG. 5. The user inputs the electronic mail address or the facsimile number of the receiving device of the scanned document from the operation unit of the Internet facsimile machine (step  1 ). Then, the original image is scanned by the scanning unit (step  2 ). The scanned image data is stored into the ROM or the like. The paper size is detected at scanning or when the document is set by the scanning unit. When the rotational transmission is not set (step  3 ), the scanned image data is transmitted by facsimile without being rotated. Alternatively, when the electronic mail address is input as the destination, the image data is attached to the electronic mail, and transmitted as it is (step  4 ).  
         [0022]    Next, it is determined whether the size of the original document in the first scan direction is the width of the short side of the A4 size paper or smaller (step  5 ). In the case the paper is A4 sized or smaller, and the paper is set such that the short side is scanned in the first scan direction, and the rotation transmission can be carried out. When the paper is a size exceeding the short side of the A4 sized paper, the image is transmitted without being rotated (step  4 ).  
         [0023]    When the electronic mail address is input, and transmitting the image by the electronic mail (step  6 ), regardless of the setting of the rotational transmission, the scanned image is attached to the header or the like of the electronic mail, and transmitted without being rotated (step  7 ). When the facsimile number is input, the original image is rotated by 90 degrees, and the image is transmitted by the facsimile. At this time, if the original image is rotated by 90 degrees, the image is transmitted by the facsimile as a landscape image which the long side of A4 sized paper is output in a width (short side) direction of A3 sized paper.  
         [0024]    According to the present embodiment, even in the case of the Internet facsimile machine which is set to transmit the original by rotating by 90 degrees, it is distinguished by whether the transmission is the facsimile transmission or the electronic mail transmission. When transmitting by the electronic mail, the scanned image is transmitted without being rotated. As a result, in the case of the facsimile transmission, the communication time or the communication expense can be saved, and in the case of the electronic mail, the recipient of the electronic mail can receive the original under an easily viewable form.
