Description

TECHNICAL FIELD The present invention relates to a facsimile device that temporarily stores read image information in an image memory.

[Prior Art] In recent years, facsimile machines 5 have been put into practical use that have effective functions such as one-time specified transmission and sequential broadcast transmission to multiple destinations.

The image information created by scanning the original to be sent is stored in a large-capacity image memory, and at a set time, the stored image information is sent to a specified destination, or multiple destinations are called in sequence, each time. The stored image information is being sent to the destination.

, 5 Usually, in such a facsimile machine, a plurality of pieces of image information are often stored in the image memory.
When an operator wants to check the image information that he or she has accumulated, he or she specifies the image information and outputs a copy to a recording device such as a plotter of a facsimile machine.

For this reason, conventionally, there has been an inconvenience in that recording paper is wasted in order to confirm input image information.

In addition, in the case of a seventh card in which only a part of the inputted image information is specified and transmitted, the distance from the leading edge of the image information is inputted to specify the portion to be transmitted.

Therefore, it is not possible to check the image information actually transmitted, which causes anxiety to the operator.

In particular, 1. If the transmission portion is incorrectly specified, the same image information must be transmitted again in response to a notification from the destination, resulting in the inconvenience of a lot of waste.

[Purpose] The present invention has been made in order to solve the above-mentioned disadvantages of the prior art, and an object of the present invention is to provide a facsimile device that can easily confirm the image information stored in the image memory. do.

[Structure] In order to achieve this object, the present invention includes a matrix-like liquid crystal display, and displays image information in a reduced form on this liquid crystal display.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a facsimile machine according to an embodiment of the present invention.

In the figure, a system control section 1 manages and controls the operation of the entire facsimile machine.

It is composed of a microcomputer system and is equipped with a large-capacity image memory 2. The operation section 3 includes
Various operation keys are provided so that the operator can operate this facsimile machine as desired, and various responses such as messages from the facsimile machine to the operator are transmitted through a large number of liquid crystal display elements arranged in a matrix ( For example, by the liquid crystal display device 4 arranged in a matrix of 64 (vertical) and 256 (horizontal).

Displayed as graphic characters or images.

Display data for this liquid crystal display device 4 is stored in a display data buffer 5 by the system control unit 1. Then, the liquid crystal display element of the liquid crystal display device 4 corresponding to the contents of the display data buffer 5 is driven by the liquid crystal driving section 6, so that a display is performed by the liquid crystal display device 4.

The scanner 7 scans the transmitted original at a predetermined resolution (for example, 8 tod h in the main scanning direction and 1 m in 7.7 lines in the sub-scanning direction).
) and converts each pixel into a black and white image signal, the output of which is stored in the image memory 2. Further, the plotter 8 records and outputs an image on recording paper at the same resolution as the scanner 7.

The communication control section 9 executes facsimile transmission according to a predetermined transmission control procedure, and transmits a facsimile to a transmission line network (for example, a public telephone line) via a modem 10 and a network control device 11 that modulates the transmitted signal and demodulates the received signal. network). *In addition, the encoder decoding unit 1□□2 encodes the image information to be transmitted using a predetermined method and converts the amount of information into a
□ At the same time, the encoded received image information is restored to the original image information.

Figure 2 shows the operation display section 2 of this facsimile machine.
0, the operation display section 20 is provided with the above-mentioned operation section 3 and liquid crystal display device 4.

In the figure, a liquid crystal display device 4 is disposed at an appropriate position on the operation display section 20 that is easily visible.

There is also a numeric keypad 21 for inputting the destination telephone number, designated sending time, number of copies, file number, etc. Telephone number key 22 for fixing the telephone number input mode.
Clear key 23 for clearing data entered from the numeric keypad 21. Start key 24 for starting transmission operations, copying operations, etc. Stop key 25 for stopping the operation of the facsimile machine, Mode key 26 for setting various other operation modes. Cursor movement keys 2F and 28 for moving the cursor (described later) that indicates the range of the transmission part, Set *-29 for confirming the position specified by the cursor, and Solving the position set using the Set key 29. Cancel keys 30 are provided at appropriate positions.

Now, when an operator stores transmitted originals in one or more configurations, the operator first sets the transmitted originals on the scanner, operates the image storage key of the mode key 26, etc. to set the original storage mode, and then presses the start key 24. Turn on to instruct the start of accumulation. Further, after operating the telephone number key 22 to set the telephone number input mode, the user operates the numeric keypad z1 to input the telephone number or abbreviated number of the destination, thereby inputting destination information. Furthermore, after operating the time designation key of the mode key 26 to set the transmission time input mode, the user operates the numeric keypad 21 to input the designated transmission time.

As a result, the system control unit 1 operates the scanner 7 to read the image of the transmitted document, and stores the obtained image signal in the image memory 2.

At the same time, the system control section 1 forms a file number for managing the accumulated image information, displays the file number on the liquid crystal display device 4, and notifies the operator. Furthermore, the system control unit 1 stores the file number in association with management information including input destination information, designated transmission time, size of the transmitted document, number of sheets of the transmitted document, and the like.

Thereafter, by specifying this file number, the operator can arbitrarily access the image information corresponding to the transmitted document.

Now, when the image display key of the mode key 26 is operated to set the image display mode, and the numeric keypad 21 is operated to input the file number of the transmitted document to be displayed, the system control unit 1 operates as shown in FIG. The image of the designated transmission document is displayed in a reduced size on a predetermined portion of the liquid crystal display device 4 by executing the document display processing routine as described above.

That is, first, the input file number is referred to and the management information having the file number is retrieved and processed 10.
1), the size of the specified transmission document is input from the management information and the size of the transmission document is detected (process 102).
).

Next, an image display area is set based on the detected document size (process 103).

For example, if the document to be sent is A4 size and portrait, the display area is set so that its longitudinal direction is fully displayed in the width direction of the liquid crystal display device 4. Also, if the sent original is A
In the case of a 5-size horizontal display, the settings are made so that the transverse direction is fully displayed in the transverse direction of the liquid crystal display device 4, and a sufficient amount of other display area can be secured. These display areas are uniquely determined by the document size.
It is also possible to set the settings corresponding to each document size in advance and store them.

Then, a reduction ratio corresponding to the document size is set (processing 104). In this processing 104, the vertical and horizontal reduction ratios are set so that the image of the transmitted original can be properly displayed in the display area set in processing '103. For example.

The original to be sent is A4 size, portrait, and the LCD display 4 is 64 in height and 256 in width.
In this case, the reduction ratio in the horizontal direction is 1138 and the reduction ratio in the vertical direction is 1736. Further, this reduction rate is uniquely determined by the size of the transmitted document, and can be set and stored in accordance with each document size.

Then, the system control unit 1 executes a reduction process 105 to reduce the image information to the set reduction ratio, and stores the display data obtained by the reduction in the display data buffer 5. At the same time, image information of 38 horizontal dots and 36 vertical dots is sequentially extracted as one dot of display data.

The number of black and white pixels in the extracted image information is counted, and the display state of the dots of the display data is set to the pixel state with the larger count value.

Next, the system display unit 1 operates the liquid crystal drive unit 6 to
The data stored in the display data buffer 5 is displayed on the liquid crystal display device 4 (process 106), whereby the display area 4a of the liquid crystal display device 4 is displayed as shown in FIG.
The image of the sent original is displayed.

In this way, the operator can confirm the transmitted document.

Now, suppose that the operator wishes to transmit only part of the transmission document. In this case, with the image of the transmission document displayed on the liquid crystal display device 4 as described above, press the edit key of the mode key 26. operate. As a result, a cursor CI is displayed in the display area 4b of the liquid crystal display device 4 to indicate the area of the image to be transmitted.

C2 is displayed.

The cursors CI and C2 can be moved to any position using the cursor movement keys 27 and 28.
To confirm the position, operate the set key 29, and to cancel the position, operate the cancel key 30. This allows the cursors CI and C2 to be set at arbitrary positions, and as a result, the area of the image to be transmitted can be set arbitrarily. Note that similar area setting is possible even when one or three or more cursors are used.

Further, the system control unit 1 stores the image area set in this way in correspondence with the transmission document, and when the transmission time of the transmission document comes, only that image area is sent to the destination as the transmission image. Send.

In this way, only a part of the transmission document can be transmitted, and since the transmission part can be visually confirmed, there is no error in the part to be transmitted, and highly reliable image transmission is possible.

Furthermore, the transmission operation by this facsimile machine.

The detailed operations of the receiving operation and the copying operation are almost the same as those of the conventional device, and are not directly related to the present invention, so a description thereof will be omitted.

Further, the size, reduction ratio, etc. of the liquid crystal display device 4 in the above-described embodiments are not limited to those described above.

[Effects] As explained above, according to the present invention, a matrix-like liquid crystal display is provided, and the image information is displayed in a reduced size on this liquid crystal display, so that the image information stored in the image memory can be easily displayed. You get the advantage of being able to check.
