Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrophotographic copying machine capable of image editing, and more particularly to a device for inputting an area to be edited.

[0002]

2. Description of the Related Art Recently, in addition to simply copying a manuscript,
An electronic copying machine equipped with an image editing apparatus that edits an image of a document and extracts only a part of the document image for copying has been developed. In such an electrophotographic copying machine capable of image editing, an area to be edited is designated and a predetermined process is performed on the image in the area. Therefore, a means for designating an arbitrary area of the image to be edited is needed.

As a method of inputting such a designated area, as disclosed in Japanese Patent Laid-Open No. 60-213168, a desired area on the original surface is designated by sequentially inputting coordinate values in the x and y directions. What is known is. That is, scales are provided on both sides of the document table, the coordinate values corresponding to the upper and lower limits of the designated area are read from the scale, and the read coordinate values are input from the ten-key pad.

[0004]

However, in the above method, the user has to confirm the position in the x and y directions for each vertex of the designated area and input the numerical value, which complicates the operation. Further, since it is necessary to read the numerical value once and store the numerical value and input it from the ten-key pad, an input error is likely to occur due to a reading error and a memory error.

Further, when the designated area is a polygon including oblique lines, it is difficult to input the designated area. The above publication also describes the case where the designated area is polygonal, but does not describe any specific means.

Further, when the image editing apparatus is used in combination with the main body of the copying machine whose paper, copying magnification and the like can be changed,
Since the area designated by the image editing apparatus is not associated with the sheet to be actually copied, the copy magnification, etc., there are cases in which copying is different from the user's intention.

The present invention is, firstly, in an image editing apparatus,
An object of the present invention is to make it possible to directly input a graphic corresponding to the specified area when designating an area to be edited and to easily create a polygonal graphic including diagonal lines.

A second object of the present invention is to change the designated area designated by the image editing apparatus according to the copying conditions of the copying machine body.

[0009]

In order to achieve the first object, an image editing apparatus for an electronic copying machine according to the present invention sequentially receives coordinates of a plurality of points for specifying an area to be image-edited in a document. A coordinate input board, a coordinate memory for storing the coordinates from the coordinate input board, means for forming graphic data corresponding to the area based on the coordinates stored in the coordinate memory, A graphic memory for storing graphic data, and means for exposing a portion corresponding to the designated area of the photoconductor of the copying machine main body or another portion based on the graphic data stored in the graphic memory. It is characterized by being provided.

Further, the image editing apparatus of the electronic copying machine of the present invention for achieving the second object includes a mode registration memory for storing the copying conditions of the copying machine main body together with the coordinates from the coordinate input board. A means for forming graphic data corresponding to the area based on the copy condition and the coordinates stored in the mode registration memory is provided.

[0011]

According to the first aspect of the invention, in the image editing apparatus of the electronic copying machine, the area of the original is specified by the coordinate input board on which the graphic corresponding to the specified area can be directly input. Therefore,
On the coordinate input board, the coordinates are input by sequentially pressing down the vertices of the figure corresponding to the designated area with, for example, a pen tip. Then, graphic data is formed based on the input coordinates, and by controlling the exposure means arranged in the vicinity of the photoconductor based on this graphic data, a copy in which a predetermined area of the original document is edited is obtained.

Further, according to the second aspect of the present invention, it becomes possible to read out simultaneously the designated area to be edited and the copying conditions on the copying machine side such as the magnification and the paper size. Therefore, when the copy magnification, copy paper, etc. are changed, the designated area is automatically changed in conjunction with this. For example, when a document is reduced and copied, the area designated by the editing device becomes smaller according to the reduction ratio of the copy.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The features of the present invention will be specifically described below based on embodiments with reference to the drawings.

In the present embodiment, an electronic copying machine that exposes a photosensitive member with reflected light from an original will be described as an example in which an arbitrary area of the original is extracted and edited.

In the drawing, reference numeral 1 denotes a copying machine main body, and a coordinate input / display device 2 is connected to the copying machine main body 1.

As shown in FIG. 2, the main body 1 of the copying machine is

The light reflected from the document D is reflected by the scanning mirror optical system 15a, converged by the lens 16, and further reflected by the mirror 15b to expose the photoconductor 11 to light. The electrostatic latent image formed on the photoconductor 11 by being exposed by the reflected light from the original is developed by the developing device 13, transferred to the paper P by the transfer device 14, and then fixed by the fixing device 17. It has become so.

Here, in this embodiment, a scanning start sensor 18 for detecting that the scanning mirror optical system 15a has started scanning is arranged near the scanning mirror optical system 15a. Further, an LED array 19 is arranged between the exposed portion of the photoconductor 11 and the developing device 13 in the vicinity of the photoconductor 11. The LED array 19 includes the photoconductor 11

Is provided.

Next, the circuit block of the coordinate input / display device 2 will be described with reference to FIG.

In the coordinate input / display device 2, the voltage from the coordinate input board 3 is supplied to the editing CPU 6 through the A / D converter 5, and the coordinates are registered in the memory 7 connected to the editing CPU 6. It is stored in the area (point input buffer). Then, the display RAM 8 is based on the registered coordinates.
Is set, and a graphic corresponding to the graphic input to the coordinate input board 3 is displayed on the graphic display 4. A non-volatile memory is used as the above-mentioned memory 7 if necessary.

A character generator 9 for outputting a predetermined message to the graphic display 4 as needed is connected to the editing CPU 6.

Next, the control circuit on the copying machine main body 1 side will be described.

A control CPU 21 is provided in the main body 1 of the copying machine, and various motors 23 such as a drum motor, an optical system scanning motor, and a paper feed motor are provided based on signals from a registration sensor 22 for detecting the position of the paper P. Control the rotation of. Further, the copying machine main body 1 has a control CPU 21.
A control panel 24 is provided for inputting various instructions regarding copying and editing.

The output of the scanning start sensor 18 is the editing CPU.
6, the data for one line of the figure corresponding to the designated area is supplied to the LED array 19 through the serial / parallel conversion circuit 25, the latch 26 and the LED driver 27 in synchronization with the copying operation. ing.

Next, the coordinate input board 3 will be described.

The coordinate input board 3 is shown in FIGS. 4 (a) and 4 (b).
As shown in FIG. 3, the spacer 3 is made up of a plate-shaped x-layer conductive rubber 31x and a y-layer conductive rubber 31y having a predetermined resistivity.
The two conductive rubbers 31 are opposed to each other through
A predetermined voltage is applied between x and 31y. When the surface of the x-layer conductive rubber 31x is pressed in the direction of the arrow with a finger or a pen tip, the x-layer conductive rubber 31x is deformed and both conductive rubbers 31x and 31y come into contact with each other. Conductive rubber 31x, 31
Since y has a predetermined resistivity, a voltage corresponding to the contact position, that is, the input coordinate position can be obtained from the coordinate input board 3 as described later. This voltage is digitally converted by the A / D converter 5 and then input to the editing CPU 6,
Input points of x and y coordinates are automatically detected.

FIG. 5 schematically shows the circuit of the coordinate input board 3, where the x-direction resistance component of the x-layer conductive rubber 31x is indicated by R _x , and the y-direction resistance component of the y-layer conductive rubber 31y is indicated. It is indicated by R _y . A resistor 33x is connected in parallel to the x-direction resistance component R _x , and a current I is applied to one end of this parallel circuit.
Is connected to the constant current source 34. Similarly, a resistor 33y is connected in parallel to the y-direction resistance component _Ry , and one end of this parallel circuit is grounded.

It is assumed that a predetermined portion of the coordinate input board 3 is pressed down and the x-layer conductive rubber 31x and the y-layer conductive rubber 31y come into contact with each other. In the figure, this contact point is schematically shown by a switch SW. In the figure, R ₁ and R ₂ are x
A value obtained by dividing the resistance Rx of the layer conductive rubber 31x at the contact point,
R ₃ and R ₄ are values obtained by dividing the resistance Ry of the y-layer conductive rubber 31y at the contact points, and R _g is an internal resistance.

The current I from the constant current source 34 is divided into currents I ₁ and I ₂ as shown in the figure, merges at the contact point, and is then divided into currents I ₃ and I ₄ , and finally the current I. Becomes and flows into the ground potential.

As can be seen from this circuit, the currents I ₂ , I ₄
Is

[Equation 1] Becomes

Since I ₁ + I ₂ = I ₃ + I ₄ = IR ₁ + R ₂ = Rx (constant) R ₃ + R ₄ = Ry (constant), I ₂ = aR ₁ and I ₄ = bR ₃ ( a, b: constants).

That is, current I ₂ , resistance R ₁ , current I ₄
Since the resistance R ₃ and the resistance R ₃ are in a proportional relationship, the x position coordinate signal can be obtained by detecting the magnitude of the current I ₂ by the resistor 33x and the differential amplifier 35x. If the magnitude of the current I ₃ is detected by the resistor 33y and the differential amplifier 35y, the y position coordinate signal can be obtained.

The reduction of the coordinate input board 3 can be detected by comparing the potential at the connection point between the constant current source 34 and the resistor 33x with a predetermined reference value REF by the comparator 36. it can. The output of the comparator 36 is supplied to the editing CPU 6 as a pen down signal (see FIG. 1).

The coordinate input board 3 has a length of 3 m, for example.
m (x direction) x 3 mm (y direction) pitch and 3 mm
It is a board having a size of 297 mm × 432 mm which substantially corresponds to the size of the document D as shown in FIG.

When the hatched portion of the document D is input as the designated area, the pen-down signal is generated by sequentially pressing the portions corresponding to the vertices of the designated area of the coordinate input board 3 as described above. The signal of the designated coordinates supplied to the editing CPU 6 is analog-to-digital converted by the A / D converter 5 and given to the editing CPU 6 through an input port (not shown) and stored in a predetermined area of the memory 7. (See FIG. 1). The coordinate input board 3 is shown in FIG.
The origin is in the upper left corner, and the y coordinate increases toward the right and the x coordinate increases toward the bottom.

As described above, the editing CPU 6 which stores the coordinates of the pressed point indicates that the graphic input has been completed by pressing the registration key provided on the control panel 24 provided on the copying machine main body 1. When the registration signal shown is input, a polygon is created by enclosing each point with a straight line in the following process. Then, the inside or outside surrounded by this polygon is controlled as an area in which a copy area can be formed, and the editing device is controlled.

The coordinates input from the coordinate input board 3 are
The data is stored in the coordinate registration area of the memory 7 by the editing CPU 6 as shown in Table 1. Here, consider the case where the first and second figures are input as the designated area.

[0039]

[Table 1] To simplify the explanation, consider the case where a triangle ABC as shown in FIG. 7 is input.

First, when the position of the point A is designated by the coordinate input board 3, the coordinates (x ₁ , y ₁ ) of the point A are stored in the memory 7 as shown in Table 1. The maximum value of the x coordinate is 99, and the maximum value of the y coordinate is 144. Next, when the point B is input, the coordinates (x ₂ , y ₂ ) are stored at the position next to the coordinates of the point A as shown in Table 1. Similarly, when the point C is input, the coordinates (x ₃ , y ₃ ) are stored.

When a registration signal is input from the control panel 24 of the copying machine body 1 in this state, the number of vertices is registered at the head of the coordinate registration area of the memory 7 as shown in Table 1.

Based on the coordinates of each of these points and the number of vertices, a straight line including a diagonal line is drawn by the algorithm described below to create a figure.

The drawing algorithm will be described with reference to FIG. In addition, in the figure, all points are assumed to be in a positional relationship of 90 ° with each other at a pitch of 3 mm.

Step: In order to connect the point A and the point B with a straight line, the space is divided into four equal parts to the upper right, the lower right, the upper left and the lower left based on the position of the point A, and the position of the point B is at which position. Or decide the vector.

Step: Next, the coordinate position is advanced in the direction of 45 ° according to the algorithm shown in Table 2.

[0046]

[Table 2] In the case of the example shown in FIG. 8, since the point B exists in the upper right direction with respect to the point A, the x coordinate may be decreased by 1 and the y coordinate may be increased by 1. That is, the new coordinates are at the upper right of point A in FIG. This coordinate is a temporary point A '(x ₁ ', y ₁ ')
And Next, the slopes of the tentative point A ′ and the line segment AA ′ of the point A are compared with the slopes of the line segment AB, and the coordinates of the next point A ₁ (x ₁₁ , y ₁₁ ) are obtained based on the following conditions. .

(A) | Slope of line segment AB |> | Line segment AA '
Of the gradient | of A ₁ = (x ₁₁ , y ₁₁ ) = (x ₁ '-1, y ₁ ′) = (x
₁ −2, y ₁ +1) (b) | When the inclination of the line segment AB | <| the inclination of the line segment AA ′ | A ₁ = (x ₁₁ , y ₁₁ ) = (x ₁ '+ 1, y ₁ ' ) = (X
₁ , y ₁ +1) (c) | When the inclination of line segment AB | = | the inclination of line segment AA ′ |, A ₁ = (x ₁₁ , y ₁₁ ) = (x ₁ ′, y ₁ ′) = ( x ₁ +
1, y ₁ +1) Since the example of FIG. 8 corresponds to the case of (a), A ₁ = (x ₁ −2, y ₁ +1).

Process: Similarly, point A ₂ (x _12, y ₁₂ )
Ask for.

A ₂ = (x _12, y ₁₂ ) = (x ₁ -4, y ₁ +2) Step: The above-mentioned operation is repeated to obtain point A
₃ , A ₄ and A ₅ are sequentially obtained, and when they overlap with the point B, the line drawing process for one side is ended.

Points A, A ₁ , A ₂ ... A ₅ are displayed by setting corresponding bits in the memory space of the display RAM 8 of 99 × 144 bits (1.782 kbytes) shown in FIG. It is stored in the RAM 8 for use.

Step: Similarly, the line segment BC is obtained. At this time, the algorithm when the vector in Table 2 is at the lower right is applied. Further, the above conditions (a) and (b) are
Since the condition is for the case where the vector is upward, when the vector is for downward as in the line segment BC, the above condition (a),
The condition in which the direction of the inequality sign in (b) is reversed is used.

Step: In the case of the line segment CA, since x ₁ = x ₃ , the horizontal line may be drawn.

As described above, the memory space shown in FIG.
A figure composed of a set of dots is formed as shown in FIG.

Further, in the memory space of the display RAM 8, all dots inside the figure surrounded by the line (triangle in this case) are set, and the figure surrounded by the line is filled. That is, this is the figure of the copy area to be obtained.

Since the memory space shown in FIG. 9 corresponds to the graphic display unit 4, the graphic display unit 4 displays the area input from the coordinate input board 3.

When the copying operation of the copying machine main body 1 is started by an instruction from the control panel 24, the output of the scanning start sensor 18 is supplied to the editing CPU 6 (see FIGS. 1 and 2). Then, the scanning mirror optical system 15
In synchronization with the scanning of the document D by a, the data for one line of the contents of the display RAM 8 is supplied to the serial-parallel conversion circuit 25 provided in the copying machine main body 1 as 99-bit serial data by the editing CPU 6. It The serial data is converted into 99-bit parallel data by the serial-parallel conversion circuit 25,
99 L's via the latch 26 and LED driver 27
It is supplied to an LED array 19 having an ED. That is, the LED array 19 is driven line by line according to the contents of the display RAM 8, and each LED of the LED array 19 blinks according to a designated area to expose a predetermined portion of the photoconductor.

Therefore, for example, if the LEDs other than the portion corresponding to the designated area are turned on, the photoconductor 11 (see FIG. 2) corresponding to the portion is exposed and the electrostatic latent image of the document other than the designated area is exposed. Disappears and only the designated area of the original is copied.

Thus, in this embodiment, the document D
The coordinate input board 3 having a size substantially corresponding to the size of the coordinate input board 3 is provided, and the designated area can be directly input as a figure from the coordinate input board 3 by pressing down the coordinate input board 3 with a fingertip or a pen tip. The operability is much better than that of inputting numerical values, and input errors are reduced. Also,
Since it is possible to specify both x and y coordinates at once,
The number of operations is reduced. Furthermore, it becomes possible to specify a region and create a figure even with a polygon including a diagonal line.

Further, since the input designated area can be displayed on the graphic display 4, the operability can be further improved by inputting while watching this display.

In particular, when a polygon is inputted, the number of points to be inputted becomes very large. However, according to the present embodiment, these points can be inputted in a short time, and the copying time as a whole. Can be shortened.

The coordinate input board 3 of the above embodiment is used.
Was using the resistance component of the conductive rubber,
The present invention is not limited to this, and any figure that can directly input a graphic corresponding to the designated area with a certain degree of resolution may be used. For example, one using a plurality of electrode panels, one using a piezoelectric element, or one using an electromagnetic induction method may be used.

The straight line drawing algorithm is not limited to the one described above.

For example, as shown in FIG. 10, the equation y = ax + b for the inclination of the line segment AB may be obtained, the x coordinate may be sequentially entered, and the line segment may be rounded off to obtain the line segment. In this case, in contrast to the original figure shown by the broken line, the figure actually obtained is shown by the solid line.

Furthermore, the figure may be formed by obtaining the coordinates only inside the line segment. However, in this case, only a graphic having a small area is formed with respect to the original graphic, and it is difficult to clearly identify the boundary because of a visual problem.

The input method may be line input instead of point input in which points are input point by point. That is, a ruler may be placed between two points and the pen point may be continuously moved along the ruler to continuously input the coordinates between the two target points.

Next, a case where the image editing apparatus according to the present invention is applied to an electronic copying machine having a memory function will be considered.

The memory function in the electronic copying machine is to register information necessary for copying such as magnification and paper size in advance, and to call it when necessary. Further, the image editing apparatus connected to the electronic copying machine can also store the designation of the copyable area as described above.

However, it is inconvenient because it does not have a function of storing both of them at the same time, that is, a function of storing the magnification, the paper size and the designation of the copyable area. For example, in copying work, it is necessary to select the magnification and the paper after calling the edit designation area. Further, in the case of copying with variable magnification, there is a problem that if the designation of the copyable area is left as it is, the intended copy area and the area actually copied will be different.

A second invention for solving such a problem will be described below with reference to embodiments.

The second embodiment of the present invention described below prevents the occurrence of unintended copying (miscopy) by making it possible to simultaneously register and call the magnification and paper size and the copyable area. .

FIG. 11 is a front view of the control panel used in this embodiment. The control panel corresponds to the reference numeral 24 in FIG.

On the control panel 24, the numeric keypad 4
1 to 50, edit key 51, mode program key 52,
A start key 53 is provided.

The ten keys 41 to 45 also function as function selection switches for selecting the editing functions of extraction, deletion, coloring, movement, and zoom, and the ten keys 46 to 50 also function as mode selection switches. Extraction copies only the designated area of the original, deletion deletes the designated area of the original, and coloring applies copying to the designated area of the original in a two-color copying machine. Further, the movement moves the position of the designated area, and the zoom changes the range of the designated area in a similar manner.

The mode program key 52 in the control panel 24, the ten keys 46 to 50 as a mode selection switch, and the start key 53 are keys necessary for storing the necessary information shown in Table 3 in the memory 7.

[0075]

[Table 3] The procedure of registration and call will be described with reference to FIG.

Step: The registration mode is entered by pressing the start key 53 after pressing the mode program key 52.

Process: Control panel 2 in this state
Magnification, paper size, and editing position are input by a predetermined key provided on the reference numeral 4 and the coordinate input board 3.

Step: When any one of ten keys 46 to 50 is pressed, the mode, that is, the copy condition including the editing position information is registered. Here, the modes are modes 1 to 5
There are 5 types of different copying conditions, and 5 different copying conditions are stored in the memory 7
You can register at.

Step: To call up the registered copy conditions, press the mode program key 52 and press the numeric keypad 46.
Pressing any one of .about.50 (corresponding to modes 1 to 5) calls the registered mode.

A state in which the actual copying condition data is stored in the memory will be described with reference to FIG.

Now, assume that the triangle ABC is registered by the editing device. However, the triangle registered at this time is an approximation of a figure in dot units as indicated by the broken line.
The original at this time is assumed to be A3 portrait size.
When registering a setting for reducing this to 50% and copying it on A5 portrait paper, the copy condition is set in a predetermined area in the memory 7 as shown in Table 4. In this embodiment, the memory 7
A non-volatile one is used. Table 5 shows the types of paper sizes.

[0082]

[Table 4]

[Table 5] At this time, the coordinates A ₅₀ B ₅₀ C ₅₀ after magnification conversion are stored instead of storing the coordinates themselves of the vertices of the triangle ABC. Therefore, the graphic display 4 displays the reduced triangle A ₅₀ B ₅₀ C ₅₀ . That is, since the designated area corresponding to the size after being scaled is displayed, the relationship between the paper to be copied (A5 portrait paper in this case) and the designated area can be intuitively understood. Therefore, there is no inconvenience such as a miscopy in which an area different from the intended area is copied. Further, since it is not necessary to check the relationship between the designated area, the magnification, and the paper size each time, the copy operation time is shortened.

In each of the above embodiments, the document D
Although the description has been given by taking the case where the image is edited in the electronic copying machine which is exposed by the reflected light from the example, it can be used for the editing in the apparatus such as the facsimile and the digital copying machine.

[0084]

As described above, according to the first invention of the present application, in the image editing apparatus of the electronic copying machine, the area of the original is specified by the coordinate input board on which the graphic corresponding to the specified area can be directly input. Then, graphic data is formed based on the input coordinates, and the graphic data is used to control the lighting of a light-emitting element array or the like arranged in the vicinity of the photoconductor to copy a specified area of the document with a predetermined edit. Is obtained.

Therefore, it is not necessary to input the coordinates of the designated area with each numerical value, and the coordinates can be inputted by sequentially pressing down the vertices of the figure corresponding to the designated area with the pen tip or the like on the coordinate input board. Therefore, it becomes extremely easy to specify the area to be edited, the efficiency of the editing work can be improved, and erroneous operations can be reduced.

Further, in the second invention of the present application, the designated area to be edited and the copying conditions on the copying machine side such as the magnification and the paper size are stored at the same time. The specified area changes automatically in conjunction with this. Therefore, copying against the user's intention is not performed.
