【Example】

 [Embodiment 1] An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG. 1 is a block diagram showing a schematic circuit configuration of a facsimile machine. The facsimile machine controls a facsimile as a whole and a control unit 1 for controlling image data supply to a display unit 11 described later. A RAM 2 for holding transmission data, reception data or a telephone number, an auto dialer 3 for dialing, an NCU 4 for controlling a line 5, and a reading section 6 for optically reading the contents of a document. , A modem 7 that performs modulation / demodulation processing, a recording unit 8 that applies heat in dot units to a recording paper by a thermal head to perform recording, a ROM 9 that stores a program necessary for the operation of the control unit 1, a ten-key pad or a one-touch In addition to keys, etc., the operation panel 1 provided with a received document display mode selection key 10a, an enlargement key 10b, a rotation key 10c, and an area alignment key 10d. And a display unit 11 including a first screen 11a and a second screen 11b, including an LCD or a CRT, and a mouse 12 as a means for designating an area on the first screen 11a. Consists of

FIG. 2 is a circuit configuration diagram showing a relationship among the control unit 1, the operation panel 10, the display unit 11, and the mouse 12. The display unit 11 has a display memory 11c, and is adapted to read out the image data stored in the display memory 11c and display it on the screen. The controller 1 writes image data to the display memory 11c. That is, when the received document display mode selection key 10a of the operation panel 10 is pressed, the control unit 1 performs pixel thinning processing for one page of the received document stored in the RAM 2 and the pixel thinning is performed. The image data of the entire one-page document is written in the area corresponding to the first screen in the display memory 11c. At this time, the display unit 11 reads the contents of the display memory 11c, so that the entire one-page document is displayed on the first screen 11a.

The mouse 12 supplies movement information to the control unit 1 when the mouse 12 is moved on a desk. The control unit 1 calculates the position of the mouse cursor on the first screen 11a based on the movement information supplied from the mouse 12, and displays the mouse cursor at that position. Then, when a switch (not shown) of the mouse 12 is pressed by the operator, the mouse cursor position when it is first pressed is the upper left position of the rectangular frame, and the mouse cursor position when it is pressed next is the right of the rectangular frame. The rectangular frame specified by the lower position is recognized as the designated area X.

When the controller 1 recognizes the designated area X by operating the mouse 12 by the operator, the controller 1 reads out the image data of the designated area X from the RAM 2 to determine the degree of pixel thinning. Writing is performed in the second screen corresponding area in the display memory 11c with a small amount or without thinning out pixels. As a result, when the display unit 11 reads the contents of the display memory 11c, the entire one-page document is displayed on the first screen 11a and the enlarged image of the designated area X is displayed on the second screen 11b. Will be displayed.

According to the above configuration, the entire one-page document is displayed on the first screen 11a, and the enlarged display is performed on the second screen 11b for the area-designated portion. While responding to the demand for downsizing, it is possible to know both the whole and details of the received document contents by the display display. If the image data displayed on the first screen 11a is thinned out and has a data amount of 1/3 of the original amount, on the second screen 11b, pixel thinning is first reduced. An image composed of all the data of 3/3 is displayed without displaying the image composed of the original 2/3 of the data amount and when the enlargement key 10b of the operation panel 10 is operated. Can be displayed. Of course, a reduction key may be provided so that the reverse process can be performed.

Further, although the first screen 11a and the second screen 11b are not overlapped in this embodiment, a two-screen configuration may be adopted in which they are partially overlapped with each other. Further, as shown in FIG. 3, the area designation may be performed in units of one line so that the second screen 11b has a width corresponding to one line of image data. Furthermore, in this embodiment, two screens are displayed on one display, but two displays may be used as shown in FIG.

Further, in the present embodiment, the mouse 12 is used as the area designating means, but the ten keys of the operation panel 10 may be used as the area designating means. That is, when the received document display mode selection key 10a is pressed and the received document display mode is activated, the function mode of the ten keys is changed, and the cursor can be moved and the frame corner can be designated by the ten key operation.

Further, when the original is set in the reverse direction or is set in the horizontal direction on the transmitting side, the content displayed on the display is also displayed in the reverse direction or the horizontal direction. By operating the rotary key 10c, it is possible to display the original content in a normal state. That is, as shown in FIG. 5, when the rotary key 10c is operated, the control unit 1 rotates the image data stored in the RAM 2 clockwise or counterclockwise by 90 ° to display memory. Write to 11c. Specifically, in the case of counterclockwise rotation, the process of writing from the lower side of the leftmost line in the display memory 11c in order from the pixels on the left side of the pixel group forming the uppermost line of the original image data Should be done. In the case of clockwise rotation, the pixel group forming the uppermost line of the original image data may be written in the display memory 11c sequentially from the uppermost rightmost line in the display memory 11c. Further, for example, when the rotation key 10c is quickly operated twice, the control unit 1 determines that a 180 ° rotation request is made and rotates the image data stored in the RAM 2 by 180 ° to display the memory. 11c will be written. The 180 ° rotation may be performed by, for example, writing from the right side of the bottom line on the display memory 11c in order from the pixels on the left side of the pixel group forming the top line of the original image data. As a result, the document contents are displayed in a normal state.

The image rotation function can be applied regardless of whether the display unit 11 has a two-screen configuration, but it is excellent when the display unit 11 has a two-screen configuration. There are advantages. That is, as shown in FIG. 3, when the area designation is performed on a line-by-line basis and the second screen 11b has a width corresponding to one line, if the horizontally-written original is set sideways on the transmitting side. However, the function of the second screen 11b is not utilized at all, but when the image rotation function is also provided, the function of the second screen 11b can be utilized even if the transmission document is set in the landscape orientation. it can.

Further, when the display is configured to be vertically long according to the vertical document, the entire document may not fit on the screen due to the image rotation described above. However, the area alignment key 10d is operated. By doing so, the original on the screen is shifted vertically and horizontally so that the entire original can be viewed. In the present embodiment, only the thinning processing is shown in the enlargement / reduction, but in the case of a display capable of gradation display, as shown in FIG. It can correspond to 4 dots of the original. That is, if four gradations are possible, the number of dots can be reduced to half of the original document dot.

[0019]

[Effect of the device]

 As described above, according to the present invention, it is possible to understand both the whole and the details of the received document contents by the display display while responding to the demand for the miniaturization of the display. Even when the document is set in the orientation or the sideways orientation, the received document can be rotated by a predetermined angle such as 180 ° or 90 °, and the document content can be displayed in a normal state.
