Abstract

PURPOSE:To set a transmission mode (such as fine, standard) by each page in correspondence to the fineness of the discription of an original at the time of facsimile transmission. CONSTITUTION:The transmission original is checked and a mode setting part 6 sets 'standard', 'fine' or the like for each page. Data from the mode setting part 6 is transferred to a setting mode memory part 7 by way of a control part 10. The signal of a page from the original reading part 1 is inputted to a reading density control part 8 by way of the control part, the setting mode corresponding to a page number is discriminated by data from the setting mode memory part and the control signal of a corresponding reading density is read from a storage part 5 so as to control the reading density, etc., of the original reading part. After being transferred to a line memory 2, data at each line from the original reading part is converted into a necessary facsimile signal by a FAX signal converting part 3 and transmitted from an output part 4 through a telephone line, etc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine in which an image quality mode can be set for each page during transmission.

[0002]

2. Description of the Related Art Some facsimile machines are provided with a function capable of switching between fine and standard modes depending on the original to be sent. For example, in the case of an original clearly written in large characters, the standard mode is used. If you select, and the original is sent at the standard speed, and if the original is a drawing with intricate lines, if you select Fine mode, it will take longer to send, but fine lines will be clearly printed at the destination. There are things you can do like this. However, for example, if the original to be sent has pages of large characters and drawings with intricate lines, and if you want to send the drawings in a clear state, you must send all pages in fine mode. Therefore, there is a problem that the transmission time is extra, although it is not necessary for the page portion of the large character.

[0003]

If there are pages in the transmission document that can be transmitted in the standard mode and pages that are desired to be transmitted in the fine mode, such a problem can be solved if the transmission mode can be switched for each page. In view of such a point, the present invention provides a function capable of switching the transmission mode to standard or fine for each page of a document, and setting the transmission mode for each page according to the state of the transmission document to provide facsimile transmission. To do.

[0004]

In order to solve the above-mentioned problems, the present invention solves the above-mentioned problems by using a document reading section for reading a document, an output section for transmitting data from the document reading section via a required communication line, and a reading density. A storage unit that stores control signals and the like, a reading density control unit that controls the reading density of the document reading unit, a mode setting unit that sets the document reading density for each page, and a setting mode that stores data from the mode setting unit A memory unit, the document reading unit, the output unit, the storage unit, the reading density control unit, and a control unit for controlling the mode setting unit and the setting mode memory unit, which are set according to a page signal from the document reading unit. The corresponding page setting mode is read from the mode memory unit, the read density control signal corresponding to the setting mode is read from the storage unit, and the original reading density is read through the reading density control unit. There is provided a facsimile quality selection scheme to control by di.

[0005]

In the facsimile image quality selection system according to the present invention, since it is configured as described above, the state of each page of the transmission original, that is, whether the page is described in clear characters or detailed characters are described. If the required transmission operation is performed after setting the standard mode or the fine mode one page at a time according to the set page, the transmission original will be printed page by page in the set mode. It is read and sent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an image quality selection system for a facsimile according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram of a main part of an embodiment of a facsimile image quality selection system according to the present invention. In the figure, reference numeral 1 denotes a document reading unit which reads a document mounted on a facsimile apparatus line by line and outputs binary data of "0" and "1". A line memory 2 records data from the document reading unit 1 for each reading line. Reference numeral 3 is a FAX signal converter which converts the data transferred from the line memory 2 into a desired facsimile signal. 4 is an output unit, which is FA
The signal from the X signal converter 3 is sent out via a required communication line. A storage unit 5 stores a control signal for reading density of a document and the like. A mode setting unit 6 sets "standard" or "fine" mode for each page of the transmission document. A setting mode storage unit 7 stores data from the mode setting unit 6. Reference numeral 8 denotes a reading density control unit, which uses the data read from the setting mode storage unit 7 to determine the setting mode corresponding to the number of pages of the transmission original from the original reading unit 1 and sets the reading density of the original reading unit 1 as standard. Or control finely. Reference numeral 9 denotes a paper feed control unit, which is the reading density control unit 8
In response to the control of the reading density of, the paper feeding speed of the document is controlled. A control unit 10 controls each of the above units.

Next, the operation of the facsimile image quality selection system according to the present invention will be described. When mounting a transmission document on a facsimile machine, first check the description density of the document one page at a time and send in standard mode (for example, 1 mm = density of 3.85 lines per millimeter) and fine mode (for example, 1 mm). Identify the pages to send with a density of 7.7 lines per). Then, the mode setting unit 6 sets the standard mode or the fine mode page by page. For this setting, press the "Setting key" →
Press "1" (page number) → press "mode key" /
Do not (when pressing once, switch between standard and fine) → Press the "Setting key" → "2" (page number)
Press →→ ...

By operating the mode setting unit 6, the modes set in page order are displayed in the display window of the mode setting unit 6 as shown in the example of FIG. Alternatively, when only one page is displayed in the display window, the display of the next page is scrolled each time one page is set. The data from the mode setting unit 6 is transferred to the setting mode memory unit 7 via the control unit 10 and recorded every time the setting is performed. It should be noted that this recording is cleared at the end of transmission of the document.

Next, after making various settings necessary for transmission, that is, inputting the telephone number of the transmission destination, setting the density of the original, etc., the originals are arranged in page order and mounted at predetermined positions, and the transmission key is pressed. To do. As a result, the transmission originals loaded via the paper feed control unit 9 are sucked one by one, and a signal of the number of pages (page number) output from the original reading unit 1 in response to the suction of the originals is sent to the control unit 10. It is input to the reading density control unit 8 via Then, the setting mode memory unit 7 is controlled via the control unit 10.
The data of the mode recorded in is read and input to the reading density control unit 8, and the mode corresponding to the page number input from the document reading unit 1 is determined. Then, the control signal of the read density corresponding to the mode is discriminated from the data read from the storage unit 5 via the control unit 10, and the read density of the document reading unit 1 or the like is controlled based on this discrimination. Further, based on the signal from the reading density control unit 7, the paper feeding control unit 9 appropriately controls the paper feeding speed of the transmission original.

Binary data from the document reading unit 1 is recorded line by line in the line memory 2 according to the reading.
It is required to be sequentially read out and input to the FAX signal conversion unit 3 to be subjected to data compression processing of continuous white pixels by the MH method (one-dimensional encoding method) or the like, and then transmitted through a telephone line or the like. Is temporarily stored in a buffer memory or the like, and then sent to the destination via the output unit 4.

[0011]

As described above, according to the image quality selection method of the facsimile according to the present invention, there are a plurality of pages of originals to be transmitted, and it is a page that can be transmitted in the standard mode and a page that should be transmitted in the fine mode. When and are mixed, the transmission mode can be set for each page. Therefore, for example, if there is a drawing in which only one page is drawn with fine lines in the manuscript of clearly written characters, only the page of this drawing is transmitted in the fine mode, and other pages are standard. Since pages can be transmitted in the mode, the transmission time is not lengthened and a page requiring fine transmission can be transmitted with fine data.
