Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image editing device, and more particularly, to an image editing device that can create an image by framing the boundary of a designated area.

[Prior Art] Conventionally, editing devices have been provided that are used by being connected to a copying machine.

The editing device has, for example, a board called a tablet, and a manuscript is placed on the tablet in a specified manner υ1, and the coordinates of the arbitrary point are inputted by suppressing the arbitrary point or the like. Note that on the copying machine side, editing copying such as erasing and trimming is executed based on the input coordinate data and the designated editing mode.

Further, as a copying machine, there is a copying machine having a special image forming mode in which copying of an original image is not performed. this is,
This is a mode in which an image of an arbitrary pattern input by the editing device is created in place of normal copying of an original image, and is used, for example, for composite copying.

111 Problems to be Solved by Invention C] In recent years, when copying a document, there has been a desire to frame a predetermined area of the document to make it stand out.

Such a frame may be created by, for example, using the editing device to continuously write line segments corresponding to the frame portion on the tablet surface (for example, by pressing the line segments using a light pen or the like provided with the editing device). ) is possible.

However, it is a troublesome method to continuously press and write line segments corresponding to the frame portions on the tablet surface. This is because tablets were originally developed with the assumption of specifying coordinate points (points), and are not necessarily suitable for writing continuous line segments.

In addition, considering that the area for which a frame is desired is generally rectangular and specifying the rectangular area is sufficient by specifying two coordinate points,
Drawing line segments is a wasteful method.

The present invention has been devised in view of the above circumstances, and provides an editing device that can easily frame any area.

[Means and operations for solving the problems] The present invention is an editing Vt position that allows for specifying a frame in an arbitrary area.

That is, the present invention includes a means for electro-optically writing image information on the photoreceptor and a means for erasing the charge in an area where image formation is not required, and a static image formed on the photoreceptor. I Developing a latent image and transferring it onto paper II! An image editing device connectable to an image forming device having a special image forming mode that does not write an electrostatic latent image based on the image information, the image editing device comprising coordinate input means for specifying and inputting the coordinates of an arbitrary point. , a frame mode key that commands the image creation mode setting of the boundary pattern of an arbitrary area, and the area is specified by multiple input coordinates, and
If the frame mode key is detected by human input, the charge on the photoconductor corresponding to the portion other than the boundary pattern of the specified area is erased, and the setting of the special image forming mode is changed to the image forming device. and till 'la means for instructing the boundary pattern to be imaged.

A supplementary explanation is given below.

(1) Imaging device used with this editing device An imaging device that has a mode (special imaging mode) that allows image creation of any pattern based on signals transferred from the editing device without copying the original. used about. An arbitrary pattern can be imaged by using, for example, a light emitting element placed close to a photoreceptor.
This is achieved by erasing the charge in areas where image formation is unnecessary.

As image information, it is assumed that not only a reflected light image obtained by exposing and scanning a document but also, for example, a laser beam modulated by a signal obtained by charging and converting the document by a TI image element.

(2> Coordinate input means, for example, press an arbitrary point on the board called a tablet,
It may be configured to generate an electrical signal whose level etc. is determined depending on the position of the arbitrary point, or a coordinate designation method by inputting Wi value data may be adopted.

Note that the method of determining coordinates by pressing the tablet includes, for example, the resistance conversion method or 1! There are magnetic induction methods, etc.

(3) It doesn't matter whether the remote key is a dedicated key or a dual-purpose key. Further, the area can be specified by, for example, specifying the coordinates of two points (two points at both ends of the diagonal line).

(4) Control means? ! A signal for setting a frame remote is generated on condition of area designation by designating a losing coordinate point and frame t-manpower. Framing mode is a mode in which only the boundary pattern of a designated area is imaged.

When the frame mode is set in the image forming device, the charge on the photoconductor corresponding to the area other than the frame area is erased, and image forming operation that does not involve original copying becomes possible. Image formation of the frame portion is realized.

[Example] The present invention will be described below with reference to specific examples shown in the drawings.

In the embodiment described below, the coordinates, and thus the area, are specified by pressing a desired point on the tablet, and the framing mode setting command is issued by using the framing key 904.

(Description of the copying machine body) First, the mechanical configuration of the copying machine and the principle of copying will be explained.

FIG. 1 is a schematic diagram showing the configuration of a copying machine main body to which the apparatus of this embodiment is connected.

As shown in the figure, the copying machine includes an optical system 5 (51 to 55) that exposes and scans a document and transmits an image, and an image forming unit 6 that reproduces the transmitted image on copy paper by an electrophotographic process.
(61 to 69), a paper feed/discharge system 7 (71 to 76) for supplying copy paper and fixing a copy image, and a glass document table 8.

(a) Optical System The optical system 5 is composed of a light source (not shown), a mirror 51, and a drive mechanism, and moves back and forth along the lower surface of the document table 8, and scans the surface of the document for exposure during forward movement. In other words, the reflected light from the original is
After being reflected by mirrors 51, 52, and 53, the light passes through a lens (transforming lens block) 55, is further reflected by a mirror 54, reaches a photosensitive drum 61, and forms an image on the surface of the drum 61. The mirrors 51, 52, and 53 are driven in conjunction with the same exposure scanning motor M3. The moving speed of the mirror 51 is relative to the circumferential speed V of the photoreceptor drum 61.
LtV/n (n:?I magnification), and the mirrors 52 and 53 are v/2n in order to keep the optical path length constant. On the other hand, the mirror 54 and the lens 55 are driven in tandem by a magnification setting motor M4. Here, the lens 55 moves on the optical axis to change the copying magnification, and the mirror 5
4 moves and swings to correct the imaging point.

(b) Image forming section 6 The image forming section 6 includes a photosensitive drum 6 that can be rotated in the direction of the arrow.
1, a main eraser lamp 62 disposed around the drum 61, a sub-charging charger 63, a sub-eraser lamp 64, a main charging charge ve5, a developing device 66, a transfer charger 67, a copy paper separation charger 68, It has a blade type cleaning device 69. Also, the main charger 65 and the developing device t! 66
An image plane erase unit (eraser) 4, which will be described later, is arranged in close proximity to the photoreceptor drum 61 between the two.

In addition, in this copying machine, the position of the inter-image eraser 4 is closer to the main V-shaft 65 than the image exposure.
The developing bag may be closer to 66.

A photoreceptor layer is formed on the surface of the drum 61, and the photoreceptor layer is sensitized and charged by passing through the eraser lamp 62.64 and the charger 63.65, and the photoreceptor layer is sensitized by passing through the eraser lamp 62, 64 and the charger 63, 65. An electrostatic latent image is formed upon slit (image) exposure.

Note that in the framing mode, an electrostatic latent image is not formed by exposure from the optical system, and the charge in the erase area (area other than the boundary pattern part of the designated area) is removed by the inter-image eraser 4. . This realizes image formation of the framed portion.

Toner is attached to the formed electrostatic latent image in the developing device f66, and the attached toner is supplied to the copy paper (via the timing roller 73 of the paper feed/discharge system 7) in the transfer charger 67. (transferred onto)

(C) Paper supply and discharge system 7 The paper supply and discharge system 7 consists of a paper upper cassette 71 and a lower paper cassette 72.
, a pair of delivery rollers 711.721 for each cassette,
Conveyance roller pair 712,713, timing roller pair 73
, a conveyor belt 74, a constant W device 75, a pair of discharge rollers 76, etc., and these are driven by a main motor M1.

Note that the toner image transferred to the paper is thermocompressed between rollers of the fixing device 75.

(Description of the inter-image erase unit 4) FIG. 2 is a perspective view of the inter-image erase unit 4 arranged close to the photosensitive drum 61.

As shown in the figure, the inter-image erase unit 4 has 64 LEs.
LED with D light emitting elements (5mm pitch) arranged in a row
The photosensitive drum 61 is equipped with an array 40 and selectively causes any LED element to emit light with a predetermined amount of light.
This removes the charge (or lowers the potential) in the corresponding area above and prevents toner development in the area.

(Description of editor 900) FIG. 3 shows an editor (editing device) 90 according to this embodiment.
FIG. In this embodiment, the editor 900 is placed on the document table 8 of the copying machine as shown in FIG.

As illustrated, the editor 900 includes a tablet 910,
keys 901 to 907.

The tablet 910 has a large number of resistance wires (not shown) arranged at approximately 1 ms intervals in the X-axis direction and the Y-axis direction, and by pressing an arbitrary point on the tablet to short-circuit it, the arbitrary point can be connected. The resistance value determined by the X and Y coordinates of the sensor is detected as a voltage level. Therefore, any point on the document (for example, the coordinate point that defines the area to be framed)
If you want to input as X and Y coordinate data, you can place the original on the tablet 910 and press the arbitrary point. Further, a coordinate scale 911 is written on the tablet 910 as a guide for specifying the arbitrary point.

Keys 901 to 907 are, in order, an erase key, a trimming key, a marking key, a frame key, an addition key, a clear key, and a registration key. The erase key is a key that commands a full erase within a designated area, and the trimming key is a key that commands a full erase outside a designated area. The marking key is a key that commands a special image forming mode (a mode in which pattern image formation is performed only by turning on and off the LED elements of the eraser 4 based on handwritten input signals sent from the editor without performing exposure using the optical system). It is. Further, the frame add key is a key for instructing image creation of a boundary pattern of a specified area, and the add key is a key for instructing data addition to registered editing data. The clear key is a key for clearing input editing data, and the registration key is a key for instructing the start of editing copying.

(Description of Iltll 1 part) FIG. 4 is an explanatory diagram of the configuration of the υll 11 part of the copying machine and the editor.

As shown in the figure, the 1llJ8 section includes a first CPU 21 that controls the main operations of the copying machine, and a second CPU 22 that controls the editor 900 and the eraser 4.

The first CPU 21 receives a key group 207 via a decoder 206.
and is connected to the display section 208. It is also connected to drivers such as the main motor M1, the main motor M2, the clutch of the timing roller 73, the automatic paper feed clutch, the electrification charger 65, and the transfer charger 67.

The first CPU 21 controls the main operations of the copying machine, such as driving the image forming section 6 and paper feed/delivery system 7, and adjusting temperature, in accordance with key manual input or sensor input.

The second CPU 22 inputs coordinate data from the editor 900 via the A/D converter 930.

In addition, signals from various keys 901 to 907 of the editor 900 are input. Furthermore, in response to a command from the first CPU 21 and a signal from the editor 900, the eraser 4
The light emission of each LED element i and II is individually controlled.

Controls the on-off of r (64).

In addition, each LED element (LED(1) to L[D(64))
Ha, i'IWAl! It is driven by the pressure VCC.

FIG. 6 is a diagram of a pit map memory used for on-off control of the LED element of the eraser 4, and FIG. 7 is a time chart illustrating the data output timing from the pit map memory.

As shown in the diagram, the pit map is 64bit x 88Lin.
1 bit corresponds to an image area of 5 mm x 5 mm. FIG. 6 is an example of trimming, where "1" indicates "rLED element off" and "0" indicates rL
"ED element on" respectively.

In addition, bitmap data starts to be read out at the falling edge of the image area signal, and each line has a total of 8 bitmap data.
Eight lines of data are read out at a predetermined timing (timing when the image on the photoreceptor reaches 5 mrrll). As a result, special image formation (marking, framing, etc.) based on pit map data is realized.

[Operation explanation] The operation of the apparatus of this embodiment will be explained below.

FIG. 8 is a flowchart showing control of the second CPtJ.

The 20th P U starts processing, for example, by turning on the power, and first performs initial settings of memory, registers, flags, etc. (8102>. Next, sets a routine timer that defines the time for one routine. 5104) ), then executes input processing from operation keys, sensors, etc. (8106:
(details later).

At 8108, the first
The determination is made based on the signal sent from the CPU.

If copying is not in progress, execute the analysis process of the input data from the editor 900 (8120; details will be described later), turn off all LEDs of the eraser 4 (S122), clear the line counter to 0 (8124), and clear the line counter to 0 (8116). Proceed to. Note that the line counter is a counter used for on-off control of the eraser 4 (elimination of marking, framing, etc.).

If it is determined in step 8108 that "copying" is in progress, the mode is edit mode (erase, trim, etc.).
(marking, framing, mode) (S

See FIG. 7; under the condition (8112>, corresponding to the fact that the image area of the photoreceptor and the eraser 4 are facing each other)
On-off of each LED element of eraser 4iIIJw
(S114: Details will be described later). This control is executed in synchronization with the image forming operation of the copying machine, thereby realizing editing image forming.

Thereafter, when the routine timer hit in 8104 ends (8116), the process returns to 5104.

FIG. 9 shows details of the 8106 (input processing) 70.
-It is diyat.

First, signals from each of the keys 901 to 907, the tablet 910, and other CPUs are input and stored in the memory (8202).

Next, the state of the stylus pen switch is determined (S20
4). The stylus pen is a pen used when specifying coordinates by pressing the tablet of the editor 900, and when the pen is pressed, the pen switch is turned on.

If the stylus pen switch is on, input the X and Y coordinate data corresponding to the position pressed by the pen and store it in memory (S206.82
08>.

On the other hand, if the stylus bend switch is in the off state,
Clearing S-input data (8210) Parts 1 and 2 of FIG. 10 are 70-item showing the details of 5120 (input data analysis).

First, the human power of the clear key is determined (8302), and if the clear key is on, the memory for edited image creation data is cleared (8304).

If the clear key is in the off state in S302, the mode setting flag is determined (8306). This flag is a flag indicating whether or not the setting of the editing image creation type (erase, trimming, marking, frame removal) has been completed (
83461).

If the settings have been completed, the process advances to 8308 and the state of the additional key is determined.

If the additional key is off (8308) and the edit mode flag is set (8316), the edit data processing Jl!
(input data analysis processing) has been completed,
Return to main routine.

If the additional key is on (8308), the edit mode flag is lowered (8310) and the process advances to 5312.

Note that the "raw mode flag" is a flag that is set when the registration key is turned on and the editing data is expanded to the pit map memory, making it possible to create an image for editing (831).

At 5312, the state of the stylus pen switch is determined.

If the pen switch is on, the above 8206.52
The coordinate data input in step 08 is stored in the editing area buffer (S314).

5312 to turn off the stylus pen switch.
Proceeding to steps 318 to 5322, the registration process is executed.

If the mode setting flag is down in 8306, the process proceeds to 5330 and subsequent steps to determine and set the type of editing image creation mode.

That is, the trimming key (8330), the erase key (S
334), frame key (8338), marking key (
8342) and set a flag according to the result (S332.3336.5340).
．． 5344).

Thereafter, the mode setting flag is set (8346) and the process returns to the main routine.

FIG. 11 is a flowchart showing details of the 8114 (eraser 111160).

First, the latch output flag is determined (8402). This flag is a flag indicating the presence or absence of a latch pulse output that defines the output of pit map data (data for one line) for eraser control.

If the latch output flag is set (8402), it is assumed that the latch pulse has not been output and the process returns to the main routine.

If the latch output flag is down (S402), the line counter is incremented 5404), pit map data corresponding to the value of the line counter is output 8412), and then the latch output flag is set (3410).

In addition, if the line counter value exceeds 88, (84
06) Since the image area has ended, output data that lights up all LEDs of eraser 4 8408)
, and then sets a latch output flag (8410).

FIG. 12 is a flowchart showing a timer interrupt &lJm for outputting the latch pulse. Note that the timer value is set to the output interval of the latch pulse.

First, the contents of the register are saved (3502), and the latch output flag is determined (8504).

If the flag is set (850/l; 8410
) and outputs a latch pulse (8506). The pulse outputs eraser control data to the driver. After that, lower the latch output flag 85
08), the saved contents are restored to the register t! (
8510), return to the interrupt routine.

FIG. 13 is a flowchart showing control by the first CPU.

First, perform initial settings 8702), set a routine timer that defines the time for one routine 5704), and execute input processing and display processing (8706.8708).
.

Next, if copying is in progress at 8710, the process necessary for the copying operation is executed (5712), the routine timer waits for completion (8724), and the process returns to step 5704.

If copying is not in progress at step 5710, determine the copy start flag (8714).

If the copy start flag is down in step 5714, the process advances to step 5724.

If the copy start flag is set in 5714 and the frame mode or marking mode is set (8716, 8718), the exposure lamp is turned off (S720) and the original image is created. prevent.

If neither the framing mode nor the marking mode is selected, the exposure lamp is turned on (8722) in preparation for copying the original image.

The apparatus of this embodiment operates as described above.

Although the above embodiment does not specifically mention the color of the frame, by changing the toner color of the printer or using a copier capable of color copying,
It is possible to frame in any desired color.

Further, although the above embodiments do not refer to composite copying, composite copying of a frame and an original image is also possible according to the present invention.

[Effect 1] As described above, the present invention is an editing II that allows frame designation with simple operations.

As described in detail in the embodiments, according to the present invention, it is possible to frame any area with a relatively simple operation of specifying coordinates and manually pressing the frame key, improving usability.
