Abstract

PURPOSE: To easily designate a read area and to recognize the area accurately by designating a magnification of an original and a size of a transmission document to display an original read area. CONSTITUTION: When the automatic setting mode of an original read size is set, a display operation section 9 displays a message and the operator designates the transmission size and the magnification. A CPU 8 calculates the original read size through this designation. Then the longitudinal and lateral length of the transmission size is obtained from a lookup table stored in a ROM/RAM section 10 depending on a designated routine size. Then the CPU 8 displays the read area in the unit of mm on the read size display section, then the operator accurately recognize the read area. Thus, when the original is sent with magnification, mistake in partial missing of the original is prevented and since it is not required to input a numeral for the operator, the operation is simplified.

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 capable of scaling a document read by a document reading means and transmitting it.

[0002]

2. Description of the Related Art In a conventional facsimile apparatus, scaling is performed by designating a document reading area (size) and a transmitted document size. Generally, the document reading area and the transmitted document size are designated. This has been done by the operator designating a desired size from among the preset standard sizes such as A3 and B4, or by the device automatically selecting it.

Further, although a facsimile apparatus that can specify the original reading area to an arbitrary size other than the standard size (hereinafter referred to as an irregular size) has already been adopted, in this type of facsimile apparatus, the operator inputs a numerical value. By doing so, or by using an expensive peripheral device such as a digitizer to digitize and input the coordinates, the original reading area is designated.

[0004]

However, among these conventional facsimile machines, only the standard size can be designated, but even if the variable scale can be designated, the transmission scale cannot be designated as an arbitrary value. It was

Further, in a facsimile apparatus capable of setting a non-standard size reading area, even if an arbitrary scaling factor can be designated, it is very difficult to know which area of the document is read and enlarged / reduced. However, there is a problem that, for example, when a document is enlarged and transmitted, an error occurs such that a part of the document is missing and is output to the destination.

Further, a facsimile apparatus capable of designating an unfixed-sized reading area, in which the original reading area is designated by inputting a numerical value, requires a complicated operation, while a digitizer or the like uses a large cost. There was a problem that it would cause a rise.

The present invention has been made in order to solve the above problems, and provides a facsimile apparatus capable of easily specifying a reading area of an original and accurately recognizing the specified original reading area. The purpose is to provide.

[0008]

In order to achieve the above object, a facsimile apparatus of the present invention is a document reading unit for reading a document and a transmission capable of scaling and transmitting the document read by the document reading unit. A facsimile device having means for specifying the magnification and the transmission document size by the operator, and the document reading based on the magnification and the transmission document size designated by the specifying means. The reading area determining means determines the original reading area of the means, and the reading area output means outputs the original reading area determined by the reading area determining means.

Further, the reading area output means is characterized in that the original reading area is numerically displayed on the operation panel.

The reading area output means may print and display the original reading area.

Further, it is preferable that the apparatus further comprises size detecting means for detecting the size of the original, and means for registering an irregular area which registers the original size detected by the size detecting means as an irregular area unique to the user.

[0012]

According to the facsimile apparatus of the present invention, when the operator specifies the scaling ratio and the transmission document size of the original read by the original reading means, the specified scaling ratio and the transmission document size are specified. Based on the above, the reading area determining unit determines the original reading area of the original reading unit, and the determined original reading area is displayed by the reading area output unit.

According to the second aspect of the present invention, the original reading area determined by the reading area determining means is displayed numerically on the operation panel.

According to the third aspect of the present invention, the original reading area determined by the reading area determining means is printed and displayed.

Further, according to the facsimile apparatus of the fourth aspect, the document size is detected by the size detecting means, and the detected document size is registered as an atypical area unique to the user.

FIG. 2 is a diagram showing an example of the configuration of the operation / display unit 9 shown in FIG. The operation / display unit 9 includes a read size display unit 21, a magnification display unit 23, and a transmission size display unit 26.

The reading size display section 21 uses the size of the original reading area designated by the operator (hereinafter referred to as the original reading size) or the transmission size and magnification (variation ratio) designated by the operator by a method described later. This is an area for displaying the required document reading size. The document reading size is designated by the reading size designation button 22. In the present embodiment, it is possible to specify a standard size such as A5, B5, A4, B4, A3, etc., and the operator automatically sets the original reading size by specifying the transmission size and the magnification. It is also possible (automatic setting mode). Further, as will be described later, the operator can previously register the irregular size so that the reading area of any size other than the regular size can be designated in the same manner as the regular size.

The magnification display section 23 is an area for displaying a magnification (variation ratio) designated by the operator or a magnification obtained from the transmission size and the document reading size designated by the operator.

FIG. 3 is a flow chart showing the procedure for setting the original reading size, the magnification and the transmission size during facsimile transmission. The program for executing this flowchart is the ROM / RAM unit 1 in the FAX board 300.
It is stored in 0 and is executed by the CPU 8.

First, the CPU 8 determines whether or not the automatic setting mode is designated as the method for setting the document reading size (step S31). If this answer is YES,
A message for the operator is displayed on the display / operation unit 9 to allow the operator to specify the transmission size and the magnification (step S32). When the transmission size and magnification are specified, CP
U8 calculates the document reading size by the following formula based on the designated transmission size and magnification (step S3).
3).

(Reading size vertical mm) = (transmission size vertical mm) / (magnification) …… (1) (reading size horizontal mm) = (transmission size horizontal mm) / (magnification) …… (2 ) Here, the vertical and horizontal lengths of the transmission size are determined in step S
According to the standard size specified by the operator in 32, R
It is obtained from a look-up table stored in the OM / RAM unit 10.

Then, the CPU 8 displays the calculated document reading size in the unit of mm on the reading size display section 21 shown in FIG. 2 as a numerical value (step S34), and ends this processing. This numerical value indicates the distance from the reference point for placing the document on the document table to the readable position, that is, the document reading area. By thus indicating the reading area of the document with numerical values, the operator can accurately recognize the readable area. Therefore, for example, when a document is enlarged and transmitted, it is possible to prevent a mistake such that a part of the transmitted document is lost and transmitted. Further, since the operator does not need to input the numerical value by himself / herself, the facsimile transmission operation can be simplified.

On the other hand, when it is determined in step S31 that the automatic setting mode is not designated, the CPU
Step 8 determines whether or not the operation performed by the operator after the operation of specifying the document reading size is the operation of specifying the magnification (step S35). The answer in step S35 is YES.
In this case, since the values of the original reading size and the magnification have already been designated, the CPU 8 calculates the transmission size based on these values (step S36). The transmission size is a value that can cover at least the size obtained from (read size) × (magnification), that is, A
Among standard sizes such as 4, A5, etc., (transmission size vertical mm) ≥ (reading size vertical mm) x (magnification) ... (3) (transmission size horizontal mm) ≥ (reading size horizontal mm) x (magnification ) ... The minimum standard size that satisfies (4) is required. Then, the obtained transmission size is displayed on the transmission size display unit 26 shown in FIG. 2 (step S37), and this processing operation is ended.

When the answer to step S35 is NO, that is, when the operation performed by the operator after the manuscript reading size designating operation is the operation for designating the transmission size, the designated manuscript reading is performed. Based on the values of the size and the transmission size, the CPU 8 calculates the magnification by the following formula (step S38).

(Magnification) = (Transmission size) / (Read size) (5) Then, the CPU 8 displays the obtained value on the magnification display unit 23 shown in FIG. 2 (step S39). , This processing operation ends.

FIG. 4 is a flow chart showing an operation procedure for calculating the document reading size and printing out the document reading area indicated by the document reading size. The program for executing this flowchart is FAX board 3
Stored in the ROM / RAM section 10 in
It is executed by U8.

First, the document reading size is calculated by the following equations (1 ') and (2') based on the set magnification and transmission size (step S41). In this step, since the document reading size is obtained in pixel units, the lookup table for extracting the numerical value used as the transmission size is the one described in pixel units.

(Reading size length) = (transmission size length) / (magnification) …… (1 ′) (reading size horizontal) = (transmission size width) / (magnification) ………… (2 ′) Next Then, the address on the raw image page memory 12 corresponding to the original reading area indicated by the calculated original reading size is calculated (step S42), and the pattern image extracted from the pattern generator 18 is written to the address (step S43). ). The calculation of the address in step S42 is performed by outputting a 400 dpi image.

When the writing of the pattern is completed, the CPU
The printer 8 outputs the image written in the raw image page memory 12 from the printer unit 6 in accordance with the normal print output sequence (step S44), and ends this processing.

FIG. 5 is a diagram showing an example of the original reading area printed out in step S44. In the figure, an outer frame 53 shows the maximum readable area of a document table (not shown) on which a document to be transmitted is placed, and a shaded area 52 shows the document reading area set by the above-described method. Also,
Reference numeral 51 indicates a document alignment mark, and when a document is placed with a similar mark provided on the document table as a reference position, the image data in the shaded area 52 is read.
By printing out the original reading area in this manner, the original reading area can be accurately recognized.

FIG. 6 is a flow chart for explaining the operation procedure for pre-registering the irregular size so that the operator can designate the reading area of the irregular size in the same manner as the regular size. The program for executing this flowchart is the ROM / RAM unit 1 in the FAX board 300.
It is stored in 0 and is executed by the CPU 8.

When the operator places an original of an irregular size on the original table and then operates an operation button (not shown), the irregular area setting mode is selected (step S
61), the CPU 8 drives the scanner unit 2 to perform scanning in the main scanning direction (step S62), and detects the length of the document in the main scanning direction based on the signal level output from the scanner unit 2 (step S62). S63). Specifically, the portion where the signal level from the scanner unit 2 is equal to or less than the threshold value is regarded as the original portion, and the length of the portion is set as the length in the main scanning direction.

Next, it is determined whether or not the length in the main scanning direction detected in step S63 is greater than or equal to the maximum value (initial value = 0) of the length in the main scanning direction detected so far (step S63). S64), when the answer is YES, the value detected in step S63 is set as the maximum value in the main scanning direction in the ROM / R.
It is stored in the AM unit 10 (step S65). If the answer to step S64 is NO, the process proceeds to step S66 without performing step S65.

At step S66, the step S63 is performed.
It is determined whether or not the length in the main scanning direction detected in step 10 is 10 mm or less. If it is not 10 mm or less, it is considered that an original image still exists on the next operation line in the sub scanning direction. Is moved to the next line, and steps S62 to S66 are repeated. When it is determined that the length in the main scanning direction is 10 mm or less, the document is considered to end at this line, and the length in the sub scanning direction at that position is set as the maximum value in the sub scanning direction.
It is stored in the / RAM unit 10 (step S67).

Then, the CPU 8 displays the stored main scanning direction length and sub scanning direction length in the read size display area 21 shown in FIG. 2, and indicates that the irregular area indicated by this size is registered. Let the operator confirm (step S6)
8).

After that, when the irregular size registered as the original reading size is designated, it can be selected / designated by pressing the reading size designation button 22 in FIG. 2 as in the case of designating the standard size. Becomes

As described above, according to this embodiment,
Since the original reading area calculated when setting the original reading size / transmission size and magnification is displayed as a numerical value in the reading size display unit 21 in mm, the operator can accurately recognize the readable area. Will be able to. Therefore, for example, when a document is enlarged and transmitted, it is possible to prevent a mistake such that a part of the transmitted document is lost and transmitted. Further, since the operator does not need to input the numerical value by himself / herself, the facsimile transmission operation can be simplified.

Further, since the calculated original reading area is printed out from the printer unit 6, the operator can recognize the original reading area more accurately.

Further, since the irregular area is read by the scanner unit 2 and the read area is registered as the original reading area, the complexity of designating the irregular area with a numerical value is eliminated and the operability is improved. Can be planned. Also,
Since the numerical value for setting the irregular size area is calculated and automatically registered, even when scaling and transmitting an irregular size original, the operator is much It is possible to specify the scaling with a simple operation.
