Description

Detailed Description of the Invention [Industrial Application Field] The present invention reads an image of a document placed on a substantially flat surface as a two-dimensional double image, and prints the read image on an arbitrary recording medium. The present invention relates to an image copying apparatus.

[Prior Art] As conventional examples of this type of image copying apparatus, for example, apparatuses disclosed in Japanese Patent Application Laid-Open No. 62-62658, Japanese Patent Application Laid-Open No. 63-42272, and Japanese Patent Application Laid-Open No. 60-143062 are known. ing.

[Problems to be Solved by the Invention] In JP-A No. 62-62658, the reading range is fixed within the range of the frame, and when copying an image of the same size as the frame, the image The reading area and the document image position can be aligned relatively accurately. However, even if you want to copy an image that is smaller than the frame, the entire image that is the same size as the frame will be copied, and if you want to copy an image that is much smaller than the frame, that small image on the original will be copied into the frame. Alignment is difficult unless you align the document and the device so that they are placed along the
After scanning the original image, in order to check which area of the image was actually scanned and at which position, it is necessary to print the image on test paper as a trial. It is very difficult to align the image with the image.

In the apparatus disclosed in Japanese Patent Laid-Open No. 63-42272, sub-scanning is performed manually, and the copy range in the sub-scanning direction can be changed arbitrarily. However, it is difficult to align the document and recording paper with the device.

In other words, the actual image reading position and image recording position are hidden under the reading/recording section of the device, so the operator cannot see the part where reading and recording are actually performed, and the original or recorded The exact positional relationship between the paper and the device cannot be known until after the copy is made.

In the apparatus disclosed in Japanese Patent Application Laid-Open No. 60-143062, the reading position can be specified very accurately for one ordinary document. However, since the 1M document must be placed face down (upside down) on the scanning surface of the device, the positional relationship between the scanning surface and the image on the document cannot be directly seen with the reader's mouth. When it is desired to copy a portion of a document that is larger than the original surface, alignment is difficult and problems such as image protrusion and skew occur. Further, the recording medium is limited to a sheet, and it is difficult to align the recording medium and the recorded image.

Therefore, the present invention aims to facilitate alignment between a document and a device when reading an image, eliminate the need for trial recording, and facilitate alignment between a device and a recording medium when recording an image. shall be.

[Means for Solving the Problems 1] In order to solve the above-mentioned common problems and to be able to read images of any size by accurately specifying the position, 1.
In the present invention, an imaging means that can be placed on any original document and reads the original image by dividing it into pixel units; a storage means that stores information on the image read by the imaging means; Coordinate input means that can be freely arranged facing a surface and whose input surface is optically transparent; Display means that can be freely arranged facing a surface of an arbitrary recording medium and whose display surface is optically transparent; an image recording means for forming a permanent visible image on a recording medium; and said imaging means.

Storage means, coordinate input means 1 Controls the display means and the image recording means, displays on the display means the range of the area specified by the coordinate input from the coordinate input means, and reads and stores the information of the document image in the area. Visible information of the read image obtained thereby, or visible information indicating the range where the read image exists, is displayed on the display means, and the read image information is sent to the image recording means and recorded. The information is recorded at a position based on the position of the display means on the medium. Provide electronic control means;

[Effect 1] According to the present invention, the range of the image read by the imaging device is arbitrarily designated by the coordinate input device. This coordinate input means has optical transparency and is placed, for example, on top of the original so as to face it, so that the visible image on the original below can be seen through the coordinate input means. be able to. Therefore, alignment of the copying device and the document when specifying one image range can be performed extremely easily and accurately.

The image of the range specified in this way is read and stored on the storage means. Further, visible information indicating the read image or the range in which the image exists is displayed on the display means. Then, the image on the storage means is printed on an arbitrary recording medium by the image recording means. The printing position is set based on the position of the display means.

In other words, when performing a printing operation, a light-transmissive display means is placed on a recording medium, and a visible display indicating the image to be recorded or its range is displayed on it, and the recording medium underneath is visible through the display means. You can see them together. The image is then printed on the recording medium in the positional relationship visible at that time. Therefore, alignment of the recording medium and the recorded image can be performed extremely easily and accurately.

In a preferred embodiment of the present invention, the input surface of the coordinate input means and the display surface of the display means are integrally configured so that they overlap. According to this, the operability during alignment is further improved, and moreover, the device is made smaller, and the space it occupies can be minimized.

[Means for solving the problem 2] In addition to solving the above-mentioned common problem, it is possible to perform independent image processing for each small region on one image, and to accurately align those regions. In order to do this, the present invention includes an imaging means that can be placed on any document and reads the document image by dividing it into pixel units; a holding means that holds independent processing parameters for each image area;
Image processing means that performs image processing of the content specified on the holding means on the information of the image read by the imaging means; Storage means that stores the information of the image processed by the image processing means; Any manuscript or record Coordinate input means that can be freely arranged to face the surface of a medium and whose input surface is optically transparent; Display means that can be freely arranged to face the surface of an arbitrary recording medium and has one display surface that is optically transparent; An image recording means for forming a permanent visible image on an arbitrary recording medium; and controlling the image processing means, the storage means, the coordinate input means 2 display means and the image recording means, and records the coordinates from the coordinate input means. The range of the area specified by the input is displayed on the display means, the processing parameters specified for the range are set in the holding means of the image processing means, and the image information read by the imaging means is transmitted through the image processing means. Visible information of the read image obtained thereby or corridor information indicating the range in which the read image exists is displayed on the display means, and the read image information is sent to the image recording means and recorded on the recording medium. Electronic control means is provided for recording a position based on the position of the display means above.

[Effect 2] According to the present invention, the image read by the imaging means is 1
The image processing means that undergoes image processing specified by the image processing means and is stored in the storage means includes a holding means that can hold independent processing parameters for each area, and performs different image processing for each area. The area to be set in the image processing means can be arbitrarily designated by the coordinate input means.

This coordinate input means has optical transparency.

For example, it is placed on top of the original so that it faces the original.
A visible image on the document below can be seen through the coordinate input means from above. Therefore, when specifying an area for image processing, the position of the area and the image position on the document can be accurately matched.

Various data required for control and special programs that do not exist on the ROM 223 are read and written on the RAM 224 allocated to the working memory area.

The DMAC 225 performs DMA control in place of the MPU 222 when another device 1, such as a floppy disk drive 227, controls the system bus 221.
The INTC 226 also processes interrupt request signals generated by various devices and controls the interrupt operation of the MPU 222. The external interface unit 240 has a plug 2

An optical sensor 251°, a magnetic sensor 252, and switches 253 to 258 are connected to the I10 port 230.

The image reading unit 180 is equipped with an overimage module 182. As shown in FIG. 4, this imaging module 182 includes three sets of solid-state imaging units (CC:D) 18.

and are arranged two-dimensionally in the Y-axis direction.

Furthermore, R, G, and B color band-pass optical filters are provided on each light-receiving surface of the image sensor.

They are repeatedly arranged in this order: R, G, B, R... Therefore, 182c is in the X-axis and Y-axis directions.

Color information in a two-dimensional area of 341 x 341 pixels can be read. The structure of this solid-state imaging unit 182c is shown in FIG. 16, and this unit 182c is used when reading an image from a three-dimensional object or a very large original.

These three imaging units are individually controlled by a drive circuit 185 that is integrated with the imaging module 182. Two imaging units 182a and 182b
The images are read at the same time and the read image data is output simultaneously, but while these are performing the reading operation, the remaining imaging units 182c do not read the images. When performing this, two imaging units 182a and 182
The read operation of b is not performed.

As shown in FIG. 2, a zoom lens 190 is provided at a position facing the imaging module 182. The imaging module 182 is supported in a slidable manner in the Y-axis direction, and as shown in FIG.
The optical axis of the optical system including the imaging unit 182a can be positioned at either a position facing the center of the imaging unit 182a or a position facing the center of the imaging unit 182c. This positioning is switched by the operator moving a slide knob 188 provided above the imaging module 182.

The location of the imaging module 182 is determined by
Identification is performed by a reflective optical sensor 251 detecting a reflective pattern (not shown) provided on the substrate of the drive circuit 185, and the identification result is read by the MPU 222.

As shown in FIG. 4, a zooming motor (ZMOT) capable of forward and reverse rotation is mounted on the outer periphery of the cell of the zoom lens 190.
195 is mounted. This motor 195 is a servo motor, and includes a rotary encoder that generates two-phase signals for identifying the amount and direction of rotation. This motor 195 is connected to the MPU 222 via a controller/driver 196, and drives the zoom lens 190 so that it has a focal length instructed by the MPU 222.

The zoom lens 190 also includes a focusing motor 1.

This focus adjustment is a so-called autofocus method, and the MPU 222 controls the focusing motor 193 based on the image captured by the imaging module 182 to automatically adjust the position of the lens 190. The focusing motor 193 is.

It is mounted on the outer periphery of a helicoid 191 fixed to the main body 200. Further, it is a servo motor capable of forward and reverse rotation, and is equipped with a rotary encoder that generates two-phase signals for identifying the amount of rotation and the direction of rotation.

It is equipped with 94. The light intensity of this is the imaging module 1
The brightness is automatically adjusted by the MPU 222 controlling the light control circuit 195 based on the brightness of the image data captured by the light control circuit 82 .

Referring to FIG. 3, an image processing unit 280 is connected to the output terminal of the image reading unit 180. The image processing unit 280 is a hardware circuit that can perform various types of image processing in real time substantially simultaneously with image reading, and has a configuration as shown in FIG.

Referring to FIG. 6, the image processing unit 280 includes processing units for shading correction, spatial filtering, gamma correction, nine-color correction, scaling, shifting, dither processing, and trimming. Note that 289 is a multiplexer that selects data obtained from either the output of the shading correction unit 285 or the system bus 221 and applies it to the spatial filter unit 281.

Each unit constituting the image processing unit 280 is controlled by the MPU 222 via the system bus 221. Various parameters for image processing can all be changed, and the MPU 222 is configured to set them as desired. .

It is also possible to perform special image processing through software processing of the PU 222.

For example, when performing enlargement or reduction processing at a very high magnification, it is necessary to significantly increase or decrease the sub-scanning speed of the imaging section or recording section. In such cases where problems are likely to occur, using software processing that is unrelated to the scanning speed makes it possible to perform high-quality scaling processing, although the processing speed becomes slower.

Different parameters can be set at the same time, and multiple types of processing can be executed at the same time. However, each unit has only one processing circuit that actually outputs processing results. Selection of the processing circuit that actually outputs the processing result is performed by 1 selection circuits 5ELL to 5EL5. These selection circuits 5ELI-8EL5 are connected to the timing/area signal generation unit 231 via the system bus 221, and the selected state is sequentially changed in accordance with the signals outputted by the timing/area signal generation unit 231, that is, in synchronization with the scanning position. Can be switched.

The image memory 140 is a bitmap-structured read/write memory for storing image data, and has a storage capacity sufficient to store one page of images.

In the scanner mode, the image memory 140 operates as a buffer memory that temporarily stores image data read by the imaging module 182. In this case, the image data stored in the memory is then transferred via the data bus 221 and the external interface unit 240 to the external device 1, for example, the personal computer 90.

In the printer mode, the image memory 140 temporarily stores image data transferred from, for example, the personal computer 90 via the external interface unit 240. Note that the single character code and graphic vector data are written after being converted into bit image data by a predetermined conversion program.

In the copy mode, in the reading stage, the imaging module 182 operates as a buffer memory that temporarily stores read image data, and in the recording stage, it operates as a memory that outputs the stored image data.

As shown in FIG. 3, a recording unit 160 is connected to the output terminal of the image memory 140. This recording unit 160 includes an on-demand type inkjet recording element. In this example, in order to enable full color recording, Y (yellow), 9M (magenta), C (
four inkjet recording heads 161Y of cyan) and K (black).

161M, 161G and 161K are provided.

Referring to FIG. 3, the displayed/entered crab knit 100 includes:
A liquid crystal display panel 121 is provided.

This display panel 121 includes a two-dimensionally arranged liquid crystal display element group with a 512×512 pixel configuration, and can display a two-dimensional image. Each display element has 1 display driver 1
26 shows a binary change between a transparent state and an opaque state. Therefore, when all display elements are made transparent, the entire surface of the display panel 121 is transparent;
light passes through it. In other words, even a visible image on the back side of the display panel 121 can be seen through the panel 121 from the front surface thereof. Furthermore, if a visible image of some kind is displayed on a portion of the display panel 121, it can be viewed overlappingly with the visible image on the back side. In this example, the display panel 12
1 is a manuscript or a recording medium (10) as shown in FIG.
It can be placed so that it overlaps the surface of the

Information to be displayed on the display panel 121 is stored in a bitmap format display memory 127 composed of a read/write memory. In this embodiment, the 1 display panel 121 displays visible information indicating the range to be read on the document and the read image in the reading stage in the scanner mode or copy mode.

In the recording stage of printer mode or copy mode, the image to be recorded is displayed. In addition, various guidance messages and key switch marks for input operations are displayed on the 1 display panel 121.

In addition to the display panel 121, the display/input unit 1OO is integrally provided with a digitizer device that can read two-dimensional coordinates in the X and Y directions. As shown in FIG. 5, two sets of light emitting diode arrays 102° 104 and two sets of photodiode arrays 103° 105 are arranged on each of the four sides of the rectangular display panel 121.

The light emitting diode arrays 102 and 104 each have one
The photodiode arrays 103 and 105 each have 128 photodiodes arranged in a line in the Y direction and the X direction at equal intervals. The optical axes of the light emitting diode array 102 and the photodiode array 103 face each other in the X direction, and the optical axes of the light emitting diode array 104 and the photodiode array 105 face each other in the Y direction. They are facing each other. Therefore, n of the light emitting diode array 102
The light emitted from the light emitting diode at the nth position of the photodiode array 103 is received by the light emitting diode at the nth position, and the light emitted from the light emitting diode at the mth position of the first light emitting diode array 104 is received by the light emitting diode at the mth position of the photodiode array 105. If there is a light blocking object such as a finger on the display panel 121 where light is received by the photodiode at the th position, the photodiode at the position that should receive the blocked light will not be able to detect the light. In this example, the photodiode array 103 can detect the position in the X direction on the display panel 121 with a resolution of 1/+28, and the photodiode array 105 can detect the position in the Y direction on the display panel 121. The position in the direction can be detected with a resolution of 1/128. Therefore, when a finger or the like is brought close to the display panel 121, the XY position of the finger can be detected. This allows input operations.

Note that the 128 light emitting diodes are sequentially energized to a light emitting state, and only the photodiodes located at positions facing the energized light emitting diodes are identified as to whether or not they are receiving light.

As shown in FIGS. 1 and 2, the display/input unit 100, in which the digitizer device and the display panel 121 are integrated, has one end that rotates around the pivot pin 206 of the device main body 200. The main body 200 can be opened from the main body 200 and placed horizontally on the document as shown in each case, or it can be closed and folded as shown by the dashed line in FIG. You can too.

Referring to FIG. 2, a light guide 123 and an optical filter 122 are provided at positions facing the back of the unit when the display/insertion knit 100 is folded. The light guide 123 uniformly guides the light emitted by the fluorescent lamp 194 to each part of the display panel 121 to achieve clear backlight illumination. The optical filter 122 has the same pitch as the pixel pitch of the display panel 121, and has R, G, and B pixels.
Bandpass filters of each color are arranged in order in a mosaic pattern. Therefore, in the folded state of the single-display/entering crab knit 100, if three consecutive pixels on the display panel 121 are controlled as one set, R2O, 83 color combinations can be displayed for each three pixels. Can display color images.

As shown in FIG. 2, a motor rotor 211 in the shape of a bow layer is exposed on the bottom surface of the main body of the apparatus.

Although only one motor rotor 211 is shown in FIG. 2, there is actually another motor rotor 201 (see FIG. 3). One surface of these motor rotors is covered with a rubber material such as chloroprene that has a large coefficient of friction against a document or paper serving as a recording medium, and the inside thereof is made of a magnetic material.

When the center of the ball is the origin of three-dimensional coordinates, this magnetic material circles around the origin of two of the three mutually orthogonal coordinate axes (i.e., the X and Y axes). In the form of.

The positions of the circumferential surface of the ball are each magnetized in a pattern in which north poles and south poles appear alternately.

212X and 212Y are field coils provided corresponding to the motor rotor 211, and the motor rotor 211 can be rotated on the same principle as a stepping motor. 212X and 212Y drive the motor rotor 211 to rotate about the Y axis and the X axis, respectively.

However, 212X and 212Y cannot drive the motor rotor at the same time, and one of them selectively drives the motor rotor. Therefore, one image processing terminal bag M340 has two
When energizing 12X, it moves in the X-axis direction, and when energizing 212Y, it moves in the Y-axis direction.

As shown in FIG. 3, the other motor rotor 201 is similarly provided with two field coils 202X and 202Y. In addition, field coils 202X, 202Y
, 212X and 212Y.

The parts that come into contact with each motor rotor are coated with a material with a low coefficient of friction, such as tetrafluoroethylene.The area around the motor rotor 211 is coated with its amount of rotation in the X direction (rotation around the Y axis). , and rotation in the Y direction (X
Two-phase magnetic rotary encoders 213X and 213Y that can detect the amount of rotation around the axis are provided. This allows the amount and direction of rotation in each axial direction to be determined. Similarly, two-phase magnetic rotary encoders 203X and 203Y are provided around the motor rotor 201, which can detect the amount of rotation in the X direction and the amount of rotation in the Y direction, respectively.

The signals output by these encoders are used to detect the amount of movement of the image processing terminal device 340 relative to the document or recording medium, and to stabilize drive control when moving it by driving the motor rotor. Ru. The driving of the motor rotors 201 and 211 is controlled by the MPU 222 via the main drive unit 214. Note that these two sets of motors are normally driven to rotate in the same direction and direction, so when driving them.

The image processing terminal device 340 does not make any rotational movement and always moves linearly in the X direction or the Y direction.

The buttons 1 of the switches 253 to 258 shown in FIG. 3 are exposed at the top of the main body of the device as shown in FIG. The states of these switches can be set by the MPU 222 as needed.

Next, the configuration and operation of the single image processing unit 280 will be explained in more detail.

Referring to FIG. 12, the configuration of one set of filters of the spatial filter unit 281 is shown in FIG.

Input data is input to the terminal Din, and processed data is output to the terminal D out. In FIG. 12, π is a multiplier, aij is a coefficient register, Dij is pixel data, and i and j are the X coordinate and ym of a pixel, respectively.
In this example, the range is 1 to 9. Therefore, the content of the calculation is shown in the sixth-order equation (1), which outputs the result of processing a two-dimensional pixel group of 81 pixels.

1) Each of the 81 coefficient registers aij is an 8-bit latch, and the coefficients it holds are
21, the lMPU 222 can be arbitrarily set. By changing the coefficients, the characteristics of this filter can be set arbitrarily. In this example, as shown in Figure 6,
Since a plurality of filters are provided in parallel in the spatial filter unit 281, each filter can be set to have characteristics suitable for smoothing, edge enhancement (improvement of blur), etc. It is possible to obtain processing results simultaneously. However, among these processing results, only one selected by the selection circuit 5ELI at that time is actually input to the next-stage gamma correction unit 282.

The selection state of the selection circuit 5ELI can be switched in correspondence with the scanning position, and the characteristics of the filter used at a pre-specified position can be switched while reading one image. Therefore, when reading one image, instructions to the 0 selection circuit 5ELL, which enables operations such as smoothing one part of the same image and sharpening the other part, are sent to the timing/area signal generation unit. 231 outputs.

Gamma correction unit 282 also includes multiple sets of correction circuits. Gamma correction is traditionally known as
It changes the image density, for example, making the background part of the image white or making it high key. The characteristics of each of the plurality of correction circuits can be arbitrarily set by the MPU 222. One output selected by one selection circuit 5EL2 from among the plurality of sets of correction circuits is output to the color correction unit 283 at the next stage.

The selection state of the selection circuit 5EL2 can be switched in correspondence with the scanning position, similarly to the aforementioned 5ELL.

The configuration of one set of correction circuits of the color correction unit 283 is as follows.
Referring to FIG. 13, the input data is R, G.
and B are applied to terminals D1*D2 and D3, respectively, and the processing results are separated for each color and applied to four sets of terminals Dol to Do4. In Figure 13,
π is a multiplier, Σ is an adder, and akij and bki are coefficient registers. The contents of coefficient register akij are
21, the MPU 222 can set an arbitrary value.

Further, a plurality of sets of coefficient register matrices are provided, and it is possible to dynamically select which one of them will be used for the actual correction calculation. For example, you can output part of the input image data in full color as it is, convert another part to monochrome, convert red to blue, or change a specific density part of a monochrome document to a specific color. Processing such as pseudo color conversion is possible.

One set of circuits of the variable magnification unit 284 has a configuration in which two circuits shown in FIG. 14 are connected in series. The first circuit performs magnification in the main scanning direction (X direction), and the primary circuit performs magnification in the sub-scanning direction (Y direction). Alternatively, unnecessary pixels caused by reduction are thinned out.

In FIG. 14, π indicates a multiplier and Σ indicates an adder.

The input image data is sequentially divided into Dixl, Di
x2 , Dix3 , Dix4 (x is 1 of the 3 types of input
), the value of the coefficient register selected is asl
, as2. ag3. When aa4 (s is 16 selection types), the content of the process is as shown in equation (2) below.

Do= Σ asj X D ixj ”(
2) The shift unit 186 moves the position of the read image in the X direction or the Y direction.

The dither processing unit 288 is a circuit that converts 8-bit input gradation data into binary data including pseudo halftone information, and in this example, a plurality of circuits are provided in parallel. Conversion parameters can be set independently for each circuit. Any one processing result is 1 selection circuit 5
It is selected at EL5 and applied to the next stage trimming unit 287.

In addition, the trimming unit 287 blanks the input data (converts it to data equivalent to white) for the designated area, and outputs a signal indicating the division of the area from the timing/area signal generation unit 231.

In FIG. 10, the timing/area signal generation unit 231
Referring first to FIG. 10, which shows the structure of the circuit and the timings of its main signals in FIGS. 7, 8, and 9.

An oscillator OSC generates a basic clock CLKO. This basic clock becomes the source for generating other signals.

Signal CLKBR is for monochrome and color imaging unit 1.
82a and 182b are used as signals indicating the timing of each pixel when image data is shifted in the X direction (main scanning direction) pixel by pixel and read out, and four recording heads 161K.

161C, 161M, and 161Y are used as clock pulses indicating the timing of each pixel when performing a recording operation. Furthermore, CLKBR is also used as a clock that indicates the timing of pixels when a monochrome image is processed by the image processing unit 280. CLKCR is a clock that indicates the timing of one unit when output data from the imaging unit 182b that outputs a color image is written into the image memory 140, and has a frequency that is ⅓ of CLKBR.

LSYNC is a main scanning synchronization signal that outputs one pulse for every l main scanning line. During one period of LSYNC, 2048 or more pulses of CLKBR appear. H.G.
ATE is a main scanning gate signal, and the period when this signal is H indicates the effective period of main scanning.
2048 R pulses appear.

RVGATE is a gate signal in the sub-scanning direction of the reading scan of the imaging module 182, and during the period when it is H, it becomes L.
The number of SYNC pulses appears the same as the number of pixels in the sub-scanning direction. This time is tay.

It is changed according to the reading scan length in the sub-scanning direction, and this change is performed by the MPU 222 adjusting the numerical value set in the gate signal generator VGG.

VBVGATH, 1llcVGATE and VMVGAT
r! , respectively.

161G, 161M and 161Y in the recording head 161
This is a signal that regulates the recordable period.

These four signals are mutually tl and tl, as shown in FIG.
t2. The phase is shifted by t3. This is because the four recording heads are arranged at positions shifted from each other in the sub-scanning direction, and the amount of positional shift and phase shift tl, t
2. t3 correspond to each other.

From the image memory 140 to the recording head 161K.

The image data of each color applied to 161G, 161M, and 161Y is controlled in synchronization with the respective gate signals. That is, the ink ejection of C, M, and Y inks starts delayed by time tl, t2, and t3, respectively, compared to the K ink. Therefore, on a recording medium on which an image is printed, C, M, and Y inks can be recorded in an overlapping manner at the same position.

Counter XC1 counts pulses generated for each pixel to generate scanning position information in the X-axis direction, and counter YCI
The synchronization signal LSYNC is counted to generate scanning position information in the Y-axis direction.

The area memory AM identifies various areas specified by the operator, and when the scanning position is in a predetermined area, each selection circuit 5ELL to 5ELL in the image processing unit 280
5EL5. Also, a selection signal is applied to the trimming unit 287.

Area memory AM is as shown in FIG.

It has an address of AO''An, and is a read/write memory in which 1 word located at one address is configured as 64 bits, and its contents are stored in the system bus 221.
The MPU 222 can be arbitrarily rewritten via the MPU 222. Each word consists of the upper 12-bit portion du (duo
-dun) #middle 12-bit part d m (d m
O” d m n ) and the lower 40 bits d
fi (dIlo-dρn), the du memory is allocated to position data in the sub-scanning direction, the dm memory is allocated to position data in the main scanning direction, and the dfi memory is allocated to selection signal data. . Furthermore, d
40 bits of Q are selected by selection circuits 5ELL, 5EL2, 5E.
6 bits are allocated to each of L3, 5EL4 and 5EL5, and the remaining 10 bits are allocated to the trimming unit 28.
It is assigned to 7.

In other words, 12 bits are assigned to each data indicating the position of the processing area in the X direction and Y direction, so
It is possible to set 4096x4096 types of positions as processing areas, and even when one position is assigned to one pixel, it is twice the reading width (number of pixels) of the imaging unit 182a, so a relatively large image can be obtained. You can also specify any area on it.

Also, 1 selection circuit 5ELL, 5EL2, 5EL3゜5EL
Since 6 bits are assigned to each of 4 and 5EL5, each of these can make 32 selections.

Note that the data of each word written to area memory AM is as follows:
They are arranged in order at addresses AO to An so that the value of the position of the area specified by them gradually increases.

Address to read data from area memory AM (80~
An) is specified by two counters XC2, YO2 which function as address pointers. counter xc
2. After the contents of YO2 are first cleared, the value of XC2 is a comparison result between the value read from dm of area memory AM (X-direction area position) and the scanning position in the X-direction @CP2. When they match, the value of YO2 is counted up, and the value of YO2 is counted up when the comparison result of the comparator CPI between the value read from du of the area memory AM (Y direction area position!!) and the Y direction scan position matches. As a result, the address specification of area memory AM is updated.In other words, the contents of area memory AM are
From O to An, they are read out in order as the image reading scan progresses. Every time the area memory read address changes,! Since the data output to the l selection circuits 5FLL-8EL5 and the trimming unit 2-87 change, the contents of one image processing are changed.

Therefore, if the sub-scanning position and main-scanning position of the position where the image processing contents change are written in order in du and dm of the area memory, the pointer will be updated every time the scanning position reaches the image processing change position. data for new image processing is read out, and the content of the processing is automatically changed.

FIG. 17 shows an outline of the operation of the MPU 222.

The operation will be described below with reference to FIG. 17.

Power is constantly supplied to the MPU 222, and the program is in a suspended state (step PL) so that the program can be executed at any time.
), which is referred to here as a halt state, means that the MPU 222 is in a halt state.

By manual operation, the operator can display and input crab knit 1.
00 is opened from the closed state shown by the dashed line in FIG. . In response to this interrupt signal, interrupt controller 226 generates an interrupt signal to MPU 222. When the MPU 222 receives an interrupt signal in the halt state, the halt state is automatically released and the MPU 222 automatically shifts to the run state.

When the MPU 222 enters a run state, that is, a state in which a program is executed, it first enters standby processing (P2).

In order to shift the MPU 222 in the run state to the stop state, the 1 display/input crab unit 100 should be closed to the state shown by the dashed line in FIG. 2. In that case, the magnetic sensor 251 issues an interrupt signal to the interrupt controller 226, and Interrupt controller 226 responsively applies an interrupt signal to MPU 222 . Thereby, the MPU 222 executes a predetermined interrupt service program, executes a halt command therein, and transitions to a halt state.

Note that if the display/entering unit 100 is closed while the button of the switch 258 is held down, transition to the halt state is prohibited. In the case of 5:, the display/entering crab knit 100 can be used as a color display.

In standby processing (P2), the status of the entire device is monitored,
Performs processing such as transitioning to a canceled state.

In step P3, it is checked whether image data exists on the image memory 140. If it exists, the next step P4 is executed. That is, the image memory 140
The above image data is displayed on the display panel 121. Specifically, image data is written onto the display memory 127. However, since the pixel resolution of the display panel 121 and the pixel size of the image to be displayed do not correspond one-to-one, the data on the image memory 140 is written. 6 display memory 12 to be written to display memory 127 after thinning out a predetermined number of pixels
The image data written on the LCD drive 12
6 is automatically displayed on the display panel 121.

Note that the operation of writing the image data on the image memory 140 to the display memory 127 is actually performed using the DMA controller 225 in order to shorten processing time.

In step P5, various types of guidance information required in the standby state are displayed on the display panel 121.

The content of the display screen on the display panel 121 at the time when step P5 is completed is, for example, as shown in FIG. 18 when there is image data on the image memory 140, and when there is no image data, for example, The result will be as shown in Figure 19.

In FIG. 18 and FIG. 19, 121d to 121h indicated by square marks respectively indicate/input crab knit 10
For example, by touching each position with a finger, the digitizer device reads that an input has been made at that position. When the MPU 222 detects this input, it executes the function of the key switch assigned to that position.

This type of key switch formed on the display/input unit 100 will be referred to as a soft key in this specification.

In FIG. 19, reference numeral 121b indicates an image displayed on the panel, and reference numeral 121a indicates a rectangular frame indicating a range in which valid image data exists.

Fig. 20 shows the display/entering crab knit 10 with the image displayed.
0 is placed on a recording medium (lO) on which a pattern 10c is printed, and the display/input crab knit 100 is shown viewed from above. Referring to FIG. 20, the pattern 10c of the recording medium located below the display/entering crab knit 100
can be seen through the display panel 121, overlapping the display on the panel.

Arrow 121 displayed on display panel 121 in FIG.
The ay mark indicates that only a portion of the image data existing on the image memory 140 is actually displayed on the display panel 121, and that the remaining displayable image exists in the direction of the arrow. In the example of FIG. 20, there are still images to be displayed at the bottom of the display screen.

In the state shown in FIG. 20, in order to view the contents of the remaining image information, connect this image processing terminal device to the recording medium or original (10
) and move the device downwards. In this case, since the apparatus moves while the motor rotors 201, 211 are in contact with the recording medium or the surface of the document, the motor rotors 201, 211 rotate as the apparatus moves. The rotation of these motor rotors is detected by the rotary encoders 203X, 203Y, 213X, and 213Y, so the direction and amount of movement of the device are determined by M.
The PU 222 can know this.

When the MPU 222 detects movement of the device, it controls the data in the display memory 127 according to the amount of movement, and scrolls the image 121b displayed on the display panel 121 in the opposite direction to the movement direction of the device. Then, the contents of the remaining undisplayed image data are displayed in the area on the display panel in which the image can be newly displayed.

Figure 21 shows the appearance of the display panel after moving the device a little towards the bottom of the screen from the state shown in Figure 20.
Referring to FIG. 21, since the entire device has moved downward, the pattern 10c that exists below the device and can be seen through the display panel has moved upward relative to the screen.
The frame 121a and the image 121b displayed on the screen 1 have also all moved toward the top of the screen.

What should be noted here is that the positional relationship between the frame 121a, the image 121b, and the pattern 10c displayed on the 1 display panel 121 has not changed between FIG. 20 and FIG. 21. In other words, even if the image processing terminal device is moved, the positional relationship between the printed image that can be seen through the display panel and the displayed image on the display panel does not change. Even if the image is considerably larger than the actual size, by displaying only a portion of the actual size image on the display panel 121 and updating the displayed image area while moving the device, the entire large image can be recorded. It is possible to accurately confirm whether or not the print image (toe) on the medium is aligned.

If the positions are not correct, you can lift one image processing terminal device off the surface of the recording medium and move it relative to the surface of the paper. In this case, even if the device is moved, the two motors will not rotate. Since none of the children 201 and 211 rotate, the MPU 222 does not scroll the displayed content, and the positional relationship between the printed image (10c) on the recording medium and the image on the display panel 121 can be changed. Although it is possible to move the processing terminal device manually,
As mentioned above, since the motor rotor can be driven, the device can also be driven by itself. Note that although we have explained the vertical direction (Y-axis direction) of the display panel here,
The display image is similarly scrolled in the left-right direction (X-axis direction) as the device moves.

This image processing terminal device is broadly classified into a scanner mode, a printer mode, and a copy mode, and these modes can be selectively used.

In the standby state described above, when a switch button (including soft keys) of the apparatus is operated or a predetermined operation request signal is input from the externally connected personal computer 90, the apparatus shifts to the various modes described above. Identification of this mode is performed in step P6 of FIG.

If a print request command is received from the personal computer 90, proceed to step pH.
Now, receive the print specifications and data of the image to be printed. The received data is stored in image memory 1.
40. When data reception and writing to the memory are completed, the next step PL2 is executed.

In step P12, the image data is converted into data in a form that can be recorded by the recording head 161 according to the print specifications. For example, since a character is received as code information, the font memory 232 is used to develop the bit pattern of the character corresponding to the character code, and the result is stored on the image memory 140. Note that the received data and the image data developed into a bit pattern are stored in mutually different address areas on the image memory 140. Therefore, the code data is also saved as is.

In step P13, the image data of the bit pattern existing on the image memory 140 is written into the display memory 127. This writing is executed at high speed using DMA.

At the end of step P13, the display on the display panel 121 becomes as shown in FIG. 19 or FIG. 20 described above, for example. In this case, the screen includes five soft keys 121d,
121e, 121f, 121g and 121h are displayed.

Step P14 shows the operator's operation. Here, if the six images for which the images and the recording medium are aligned are too large to fit on the screen, the operator selects one image processing terminal device as described above. By moving the
By scrolling the displayed image, it is possible to check whether each part of the entire image is aligned with each part of the recording medium. The image is displayed on the display panel 121 in its actual size at the time of recording. However, since the pixel density of the display panel is coarser than the pixel density during recording, the quality of the displayed image is slightly inferior to that of the recorded image.

In step P15, soft key 121h on the display screen is pressed.
Waits for an input operation to be performed on .

If there is an input, the process proceeds to the first step 16.

In step 16, printing is actually performed on the recording medium. What is important here is to accurately record the image as aligned in step 14, that is, so that the display position of the image on the display panel 121 matches the position of the recording medium located below.

In step 16, the MPU 222 first controls the main drive unit 214 to drive the motor rotors 201 and 2.
11 to move the entire image processing terminal device along the surface of the recording medium in the Y-axis direction. Then, the recording axis of the black recording head 161 is positioned so that it coincides with the leading edge position of the displayed image (in the case of 201m, the upper broken line portion of 121a) before the apparatus moves. Positioning in this case is performed by controlling so that the distance from the position of the recording head 161 to the leading edge position of the displayed image on the display panel matches the moving distance detected by the rotary encoder.

When the positioning is completed, the MPU 222 issues a data output command to the image memory 140, a recording start command to the recording heads 161, 161G, 161M, and 161Y, and a constant speed running command in the Y direction to the main drive unit 214. Each is output via the driver 221.

If the X direction is called the main scanning direction and the Y direction is called the sub-scanning direction, the motor rotors 201 and 211 cause the device to run at a constant speed in the sub-scanning direction. In addition, the recording head 161
, 161C, 161M.

161Y each includes 2048 nozzles arranged in the main scanning direction. Therefore, each print head can print a two-dimensional image with a 2048Xn pixel configuration for each color.

Recording is performed for each main scanning line, and for each line,
Recording for each of the 2048 pixels is performed serially. When recording of one line is completed.

The image processing terminal device moves by one pixel in the sub-scanning direction and proceeds to recording the next one line.

During this recording operation, the image to be recorded is displayed on the 1 display panel 121, and the content of the 1 display changes as the device moves.
It is displayed in the same way as in step P14. However, in this case, the display position is scrolled according to the currently recorded position on one image.

In step P17, since the print operation has been completed, a completion status is sent to the external personal computer 90.

When a scan request command is received from the personal computer 90, the process first proceeds to step P21.
At 21, data of scan specifications to be applied is received. This data is then written onto image memory 140.

In the next step P22, the received scan specification data is decoded and processing is performed according to the data. Execute content settings, etc.

In step P23, the same process as in step P13 described above is executed.

The simplest scanning specification is when the entire range of the display surface of the display panel 121 is read. In that case, the display on the display panel 121 will be as shown in FIG. Also, trimming a variable circular area (reading only the inside of that area)
In the case of a scan specification including a request for 1, a screen as shown in FIG. 23, for example, is displayed. In the example of FIG. 23, the image of the portion inside the circular broken line mark 121a indicating the range of the area is extracted and read. Note that 121bl and 121b2 are soft keys for instructing to reduce and enlarge the diameter of the mark 121a, respectively.

Step P24 shows the operator's operation, in which the operator aligns the device and the document,
Set the reading area. The entire range of the display surface of the display panel 121 is read. If a simple scan specification is set for I&, it is sufficient to simply align them so that the image desired to be read on the document falls within the display surface of the display panel.

If your scan specifications include cropping specific areas or designating special areas that require special image processing, the portion of the image on the document that corresponds to that area may be It is necessary to perform more fine alignment so that the actual size area display marks indicating the processing area displayed on one display panel coincide.

Further, the scan specifications may include a request for the operator to specify an area. In that case, it is necessary to input the coordinates and specify the area using the digitizer of the image processing terminal device. Further, the scan specifications may include only the basic shape of the area as information about the area. In that case, since the basic shape is displayed on the display panel 121, it is necessary to transform it using soft keys and specify the area.

If the scan specification is variable circular cropping,
For example, it becomes as shown in FIG. In this example, sentence 10a
The apparatus is shown placed on an original (lO) on which an elliptical pattern 10b is printed. Here, for example, if you want to enlarge the size of the trimming, you can perform an input operation (touch) on the soft key 121b associated with the enlargement operation.As shown in FIG. The size of the circular dashed line shown is enlarged.

The alignment between the document and the image processing terminal device can be performed by moving the device over the document, as in step P14 described above.

The reading range specified in the scan specifications is displayed on the display panel 121.
If the reading area is larger than the display range, that is, if the entire reading area does not fit within the display panel 121, a display as shown in FIG. 26, for example, appears. Here, the arrow display 121a indicates the reading range, 121ax indicates that the reading range is expanding further to the right (X direction) than the display range, and 121ay indicates that the display range is further below the display range ( This indicates that the reading range is expanding in the Y direction). Further, 121s is a mark indicating the range of a designated area within the reading range (121a) where more special image processing is to be performed. 121syl and 121sy2 indicate that the range of the area does not fit on the display. Here, special image processing means changing, for example, sharpness, nine tone tones of density gradation, image displacement, dither pattern, etc. for other areas. These image processes are performed in real time by one image processing unit 280 at the time of image reading.

Scan specifications may be set in which the reading range is arbitrarily specified. In that case, the MPU 222 stores the ROM in advance.
223 as fixed area shape data, and the RAM 224 as user defined area shape data.

It is displayed on the display panel 121. In that case, for example, the second
A screen like the one shown in Figure 7 will be displayed.

In FIG. 27, 121i, 121j, 121k
and 121 Q is a fixed region shape pattern, and 12
in indicates a pattern of a user-defined area shape. These display patterns indicate the range of the target area when performing trimming or special image processing.

Furthermore, soft keys are formed at the positions of each display pattern.

When one input operation is performed on these soft keys, an area pattern at that position is picked up, and when the second input operation is performed, the area is fixed in a similar shape to that position. 121m shows the result after picking up one area pattern 121n and setting the position and shape. In addition.

When specifying an area such as 121m, an input mode for directly specifying the area may be used instead of using the basic area shape displayed on the screen as a menu. That is, for example, by moving the fingertip so as to draw a locus of a desired area pattern while keeping the fingertip within the reading area of the digitizer, the area is set on the part of the locus. The shape of the region set in this way can be registered in the RAM 224 as a user-defined region shape and used again later.

Regarding the area shape pattern soft key, if you input another key 121e before performing the second input operation, the area pattern you picked up will rotate 15 degrees.
For example, the area shape pattern 121b is the pattern 121
After picking up Q, input operation is performed on the soft key 121e six times, and the result is obtained by rotating the soft key 121e by 90 degrees.

In addition, when inputting two points without picking up any area shape pattern, set the two points as diagonals.
A rectangular area is set. 121a in FIG. 27 is 12
It shows the range of the area set when two points 1apl and 121ap2 are input.

When predetermined inputs are made regarding these areas, the results are immediately calculated by the MPU 222. And MPU22
2 sets various image processing parameters for the image processing unit 280 and also sets the contents of the area memory in the timing/area signal generation unit 231. Once all these settings are completed, image reading can be started at any time. can.

Even if the area is larger than the inputtable range of the display/input unit 100, the image can be read by specifying the area with the image processing terminal device.

The operation in that case will be explained.

First, one point p1 is input in the state shown in FIG. 19a.

That is, the user touches the pl position with, for example, a fingertip.

In that case, the MPU 222 identifies whether the point pt belongs to the left, right, upper or lower side of the center of the display panel, and marks a line segment indicating the range of the area from the point p1 toward the half area to which it does not belong. 121ax.

Draw 121ay.

After that, when the operator moves the image processing terminal while keeping it in contact with the original, a screen like that shown in FIG. 29b, for example, is displayed. Note that 10a in Fig. 29b is the printed pattern on the manuscript.6 Next, when point p2 shown in Fig. 29c is input,
The display on the screen changes as shown in FIG.
ay appears.

If it is desired to perform special image processing on a specific area within the reading area set in this manner, the following operation is further performed. First, return the position of the image processing terminal device to its initial state and display the screen shown in Fig. 29a, and in that state, input the two points P3*P4. In the screen shown in , point p5
Enter. As a result, as shown in FIG. 29d, a rectangular frame 121S indicating the range of the set area is displayed.

The content of the image processing within the area indicated by this frame 121g is as follows:
The operator can make any selection by operating the soft key 121g. That is, when 121g is input, the previous display is erased, and a partial image processing content selection screen (not shown) is displayed on the display panel 121.This screen is displayed. When you are in the screen, you can interactively select the image processing content within the specified area.After this operation, you can return to the original screen state by entering the screen return softkey displayed on that screen. By inputting the soft key for starting reading, the user can immediately proceed to the next reading operation in step P26.

Note that it is also possible to set a special area for @ image processing inside the area to be trimmed.

In step P25, the process waits for the soft key 121h to be input. If there is an input, the process first proceeds to step P26.

In step P26, the image is actually read according to the scan specifications set in the previous processes.What is important here is that there is no positional deviation between the specified reading position and the position of the image that is actually read. should not occur.

Specifically, when no special reading area is specified, the image of the area on the document that is facing the inner part of the display/input range of the display/input unit 100 at the time of alignment is read. is important, and when a reading area is specified, it is important to read the image of the area on the document that is opposite to the rectangular frame indicating the reading area displayed on the screen during alignment. , if there is a special area designated for further cropping or image processing in the scanning area, a positional shift may occur with respect to the image of the area on the document that was facing the frame indicating the range of that area. This means performing cropping and image processing without the need for image processing.

In this embodiment, when aligning, the printed image on the document and the display such as a frame indicating the area on the display panel 121 appear to overlap, so the alignment is accurate and the image is actually read from that point on. Unless there is a slip between the device and the document, there is no risk of misalignment.

If the size of the set reading area is equal to or smaller than the size of the display panel 121.

The MPU 222 includes an imaging unit 182a and a lens 190.
A movement amount is given to the main drive unit 214 such that the conjugate point of the main drive unit 214 moves to the position of the edge of one display panel 121 in the sub-scanning direction (above 121 in FIG. 18).

Also, the size of the set reading area is different from the display panel 12.
1, the MPU 222 determines that the conjugate point between the imaging unit 182a and the lens 190 is at the edge of the frame (26th
The amount of movement that would move to the position (12fax) in the figure,
to the main drive unit 214.

The main drive unit 214 includes the motor rotor 201
, 211 and is controlled so that the amount of rotation detected by the rotary encoder matches the specified amount of movement, thereby positioning the device at a predetermined position.

After this alignment is completed, the main drive unit 214
applies a completion signal to the MPU 222, the MPU 222
Inputs an imaging start command to the imaging drive circuit 185, a processing start command to the image processing unit 280, and an image memory 1.
Data input command to 40.

A constant speed running command in the Y direction is applied to the main drive unit 214 via the system bus 221, respectively.

If the X direction is called the main scanning direction and the Y direction is called the sub-scanning direction, the motor rotors 201 and 211 cause the device to run at a constant speed in the sub-scanning direction. Also, the imaging unit 182
The element group at each pixel position a and 182b has 2048 pixels lined up in the main scanning direction. Therefore, by moving the device by n pixels by sub-scanning, a two-dimensional image of 2048Xn pixels can be read during that time.

Image reading is performed every l line of main scanning in synchronization with signal LSYNC, and in each line, pixel synchronization signal CLKBR
2048 pixels are sequentially read in synchronization with . The read data is subjected to image processing by the image processing unit 280, and then transferred to and written into the image memory 140.

The image memory 140 has a variable bit configuration of words in units of access, and for monochrome image data, one word is 8 bits, R, G.

For B color image data, l word 24 bits,
For C, M, and Y color image data, one word has a structure of 32 bits.

The process of step P26 is continued until the sub-scanning end position is reached and images in all the reading areas are read. Further, during this reading operation, various areas displayed on the display panel 121 are scrolled as the device performs sub-scanning. Furthermore, the contents of the read image are sequentially displayed in real time on the display panel 121 starting from the line for which image processing and writing to the image memory have been completed.6 Therefore, wait until scanning of all reading ranges is completed. The operator can immediately view and confirm the reading result of the part of the image for which reading has been completed. If the desired result is not obtained, the reading can be stopped by operating a switch.

Next, some examples of operations related to image reading will be described.

In the example of FIG. 27, the frame 12 indicating the range of each processing area
The trimming range is set by 1a, 121b, and 121m. In this state, soft key 121h
When an input operation is performed, image reading starts. As a result, the screen shown in FIG. 28 is displayed. Comparing FIG. 27 and FIG. 28, frames 121a, 121b, 121
It can be seen that only the range specified by each of m was extracted as valid image data. Note that the frame 121a.

The information 121b and 121m is stored in the RAM 224 and separated from the image data on the image memory 140.

In the example of FIG. 30a, a frame 121a indicating the range of the processing area
The processing content is specified to perform a predetermined color conversion in the section. In addition, in FIG. 30a, 10b, lOc,
lOd and 10x are images printed on the original (10), and are visible through the display panel. Chapter 30a
When an input operation is performed on the soft key 121h in the state shown in the figure, image reading is started, and as a result, the screen shown in FIG. 30b is displayed. The read image 121bl shown in FIG. 30b has a different color from the image 10b on the original.

In the example of FIG. 31a, an arbitrary designation command is received from the personal computer 90, and the operator makes settings to perform different image processing on a plurality of arbitrary regions.

Specifically, in the frame 121a indicating the area, the gamma correction unit 282 is set to low key, in the frame 121b, the color correction unit 183 is set to perform color conversion, and in the frame 121m, the spatial filter unit 281 is set to perform line thinning processing, and other parts are set to perform standard image processing. When an input operation is performed on the soft key 121h in the state shown in FIG. 31a, image reading is started, and as a result, the
The screen shown in the figure will be displayed.

In the explanation so far, the movement of the image processing terminal device during image reading and printing operations is performed by magnetically driving the motor rotors 201 and 211.

We have explained the case where the device is self-propelled, but since such self-propulsion consumes a large amount of power, it is recommended that the image processing terminal device uses a battery as a power source and cannot obtain power from the host computer. In some situations, the available time of the device is severely limited.

Therefore, if it is desired to reduce power consumption, the device is configured so that it can stop moving by itself and can be moved manually by the operator. In that case, information indicating the position and direction of movement is displayed on the display panel 121.

In step P27, since the image reading operation has been completed, a completion status is sent to the external personal computer (host computer) 90.

When the operator presses the button of the switch 255, the system enters the file mode and proceeds to step P31. In this step, a menu screen is displayed on the display panel 121 in order to wait for the operator's instructions regarding file operations. This menu screen displays images from disk 80 to image memory 1.
Information for selecting whether to transfer image data to the image memory 140 or to transfer data from the image memory 140 to the disk 80 is included.

In step P32, the operator inputs the file name and the like.

In step P33, the presence or absence of an input operation on the two soft keys (save and load) displayed on the display panel 121 is checked, and if there is an input to save, the process advances to step P34.

If there is a load input, the process advances to step P35.

In step P34, the image data on the image memory 140 is transferred to the disk 80 and stored therein. This step also includes processing to compress the data.

In step P35, the image data stored on the disk 80 is transferred onto the image memory 140. The compressed data is written to the image memory 140 after data decompression processing is performed.

Next, the case of copy mode will be explained. There are two types of copy modes. One is a mode that uses one image processing terminal device, and the other is a back-to-back mode that uses two image processing terminal devices. When the wired interfaces 242 of two image processing terminal devices are connected to each other by a cable, this is identified by the program in the ROM 223.

Back-to-back mode is automatically activated.

The copy mode is roughly divided into three steps: setting a reading mode, executing a reading operation, and executing a recording (print) operation. However, in back-to-back mode, one side performs the reading operation and the other side performs the printing operation at the same time.In pack-to-back mode, one side performs the scanner mode and the other side performs the printing operation simultaneously.
The other mode is almost the same as the printer mode, so its explanation will be omitted. The normal copy mode will be explained below.

When the button of the switch 254 is pressed, the process proceeds to step P41. In this step, a menu screen for copy mode setting is displayed on display panel 121. This screen is shown in Figure 11a.

In Fig. 11a, 121cl is sharpness adjustment;
121g is gradation adjustment, 121c is color adjustment, 121g is magnification adjustment, and 121j is position adjustment (shift).

121 indicates soft keys respectively assigned to area processing settings.

For example, when an input operation is performed on the soft key 121k, operations such as trimming as shown in FIG. 27, specification of a processing area, and setting of image processing contents can be performed.

Regarding the input of a specific area, referring to FIG. 31, when the soft key 121e is input after inputting the area, selectable processing for each image processing step, for example, high contrast, low contrast, high key, is selected in the gamma correction processing step. , a selection menu appears in the form of a low key, allowing input in association with the area.

For example, when the soft key 121e is input, the gradation setting screen shown in FIG. 11b is displayed, and by touching the touch marks 121adj+, 121adj-, and 121adja, an arbitrary characteristic 121adj can be set from the standard characteristic 121st. can. 121i is a soft key for returning to the original screen (FIG. 11a); 111b is a soft key for starting image reading;

Step P42 represents an input operation by the operator using the menu screen.

In step P43, the copy specifications set in P42 are computed and developed, processing parameters are set in the image processing unit 280, and when there is trimming or area processing, data is written to the area memory of the timing/area signal generation unit 231. It's crowded.

Step P51 is performed by pressing the soft key 12 on the screen shown in FIG. 31a.
This step is executed when 1h is touched, and a reading operation is executed in the same manner as step P26 described above. The image data read every main scan is ii! The image processing unit 280 processes the image, converts it into recording data, and stores it in the image memory 140. At the same time, data suitable for display is also calculated by the MPTJ 222 and written into the display memory 127.

Step P61 is a process of executing a print operation. Here, for example, the screen shown in FIG. 22 is cursed. This screen has been read and image processed according to the specifications set in step P41, and a read image 121a corresponding to the image data existing on the image memory 140 and a plurality of soft keys are displayed on the display panel 121. be.

One of these softkeys is Key 1 to start recording.
21h, and if this is touched, image data is immediately sent from the image memory 140 to the recording head 160 and a printing operation is executed. That is, substantially the same image displayed on one display panel 121 is recorded on the recording medium directly below the display position. Again, one important thing is that what the operator sees on the display means is recorded as a permanent visible image on the recording medium.

Therefore, for example, if there is a preprint such as ruled lines on the recording medium, it is possible to appropriately align the recording position. The position is to lift the loading device from the recording medium,
Adjustable by releasing and moving.

Furthermore, even if the recording range is larger than the display panel 121, by moving the recording medium and the device without separating them, the screen will scroll, allowing you to check whether the recorded image is extending out or the recording position is biased before recording. .

The remaining soft keys on the new screen are keys for re-image processing, and if these keys are touched, a menu screen for re-image processing will appear. Re-image processing is
- The image data in the image memory 140 that has been read is subjected to image processing again. For example, when an image as intended by the operator does not appear on the display panel 121, or when an image is read from a document.

If you want to obtain multiple recorded images that have undergone slightly different transformations (image processing), use JMii! Since there is no need to repeatedly read the ii image, the image data on the image memory 140 is reused, processed again by the image processing unit, and the processing result is output as a recorded image.

The menu screen for re-image processing is the same as the menu screen in step P41. That is, sharpness adjustment,
Fluff tone adjustment, density adjustment, single color adjustment, magnification adjustment, trimming, etc. can be set by the operator. The re-image processing specifications set here are arithmetic processed by the MPU 222, and then processing parameters are set in the image processing unit 280, and when there is a trimming area setting, it is stored in the area memory of the timing/area signal generation unit 231. After writing the data, the DMA controller 22
5, a predetermined address in the image memory 140 is set as the transfer source address, and the address of the multiplexer 289 of the image processing unit 280 is set as the transfer destination address, and DMA data transfer is executed. As a result, the image data is subjected to image processing again, and the display panel 12
1 will be displayed again on top.

In the above embodiment, a light-transmissive liquid crystal display was used as a display means so that the displayed image and the image on the document or recording medium could be seen to overlap, but the reading range and recording range may vary depending on the display/input range, for example. If the area is limited to an area that approximately matches the outline of the crab unit 1°O, it is relatively easy to distinguish between the range of the image to be processed and the original or recording medium, even if the display/input crab unit 100 is not made transparent. It can be aligned to In that case, as the display means, for example, an opaque EL display device may be used. If the EL display device is used, color display becomes possible.

Next, a modified example will be described.

FIG. 32 shows the external appearance of the image processing terminal device in the second embodiment, and FIG. 33 shows the internal structure of the device in FIG. 32. Similarly, FIGS. Indicates an image processing terminal device.

FIGS. 37 and 38 show an image processing terminal device according to the fourth embodiment, and FIG.
FIG. 2 shows a block diagram of a device configuration that is substantially common in the embodiments of FIG.

First, the second. Regarding the third and fourth embodiments, differences from the above-described first embodiment will be briefly explained.

(1) Image reading, 9-image display, 9-image recording color functions,
A three-dimensional object imaging function, an autofocus function, and a floppy disk drive are omitted.

(2) A digitizer device for inputting coordinates was constructed by arranging a large number of pressure-sensitive electrical contacts within a flexible, transparent film. Further, as a display device, a light-transmitting liquid crystal display panel formed in the form of a flexible film is used.

(3) The motor of the main body of the apparatus containing the image sensor and recording means can only be driven in the Y direction (sub-scanning direction).

(4) The range of image reading and image recording is limited to the coordinate input range of the digitizer (same as the display range of the display panel) when the motor automatically drives the sub-scan.

(5) The display means does not move with respect to the original or the recording medium, so images, etc. are not scrolled on the display screen.

(6) Use an LED array to illuminate the original.

(7) The image sensor is only a one-dimensional COD.

Next, the second. The configuration common to the third and fourth embodiments will be described with reference to FIG. 34. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals.

The image of the document illuminated by the LED array 394 is read by the imaging unit 382. The imaging unit 382 is C
It is a solid-state imaging device using OD.

It has light receiving elements for 2048 pixels in the X direction.

The image data output from this imaging unit 382 is
The signal is applied to image memory 140B. The image memory 140B is composed of a card-type read/write memory (RAM) with a built-in backup power supply, and is detachable from the main body of the image processing terminal device.

When performing a recording operation, the data on the image memory 140B is sent to the recording unit 361, and an image is printed on a predetermined recording medium. The recording unit 361 is
It is equipped with an on-demand inkjet recording head. Recording should be done in one color.

The display panel 321 (521, 721) has a structure in which a liquid crystal material is sealed between two flexible transparent resin films on which transparent electrodes are deposited in a grid pattern.
It has a display resolution of 12 x 512 pixels, and can be controlled to be transparent or opaque on a pixel-by-pixel basis.

On this display panel, the range of the document to be read and the read image are displayed at the reading stage in the scanner mode or copy mode. Furthermore, in the recording stage of the printer mode or copy mode, the image to be recorded is displayed. Furthermore, various guidance messages and soft key marks are displayed.

The digitizer unit 300 (500, 700) consists of two flexible transparent resin films on which transparent electrodes are vapor-deposited in a grid pattern, which are pasted together with the grids perpendicular to each other, and a thin transparent insulating film is sandwiched between them. It was glued together. By pressing with a fingertip or the like, the opposing electrodes on the two films come into contact and become electrically conductive. The coordinates can be identified by detecting whether any of the many electrodes is conductive.

For coordinate identification, scanning circuits 302, 304 and detection circuits 303 and 305 are provided for the X and Y axis electrode groups, respectively. Scanning circuits 302, 304 and detection circuit 30
3, 305 is data of detected coordinate values controlled by the detection control circuit 306.

The data is transferred to the MPU 222 via the system bus 221.

Next, a second embodiment will be described with reference to FIGS. 32 and 33.

The digitizer unit 300 and the display panel 321 are stacked in the thickness direction and are integrally configured. 33rd [
A drive shaft of an electric motor (not shown) is coupled to the shaft 412 shown in FIG. A spool 411 is fixed to the outer periphery of the shaft 412, and one end of the digitizer unit 300 and the display panel 321 are fixed to the spool 411. Both the digitizer unit 300 and the display panel 321 are flexible and are wound around the outer periphery of the spool 411 when it rotates.

In this embodiment, when performing sub-scanning in the Y-axis direction,
It is necessary for the operator to fix one end 300a of the digitizer with a finger or the like. With one end 300a fixed (for example, pressed against the bottom surface with a finger), clockwise in FIG. 33,
When the spool 411 is rotated, the digitizer 300 is wound up.

The main body 400 of the apparatus is driven in the sub-scan direction toward the right.

Also, with one end 300a fixed, the device main body 400
You can also move it to the left side manually. That is, in this example, sub-scanning in the right direction is automatically performed, and sub-scanning in the left direction is performed manually. Note that if the digitizer unit 300 and the display panel 321 have appropriate buckling strength, manual scanning becomes possible even when sub-scanning to the right.

Even when sub-scanning is performed in the Y-axis direction, if one end 300a is fixed, the digitizer unit 300 and display panel 321 will not move relative to the document or recording medium placed below, and the device body will not move. Only 400 move. Since the apparatus main body 400 is equipped with a reading optical system and a recording system, by sub-scanning them, it is possible to perform sub-scanning of one image reading and image recording.

In this embodiment, the image of the document placed in contact with the lower surface of the apparatus main body 400 is illuminated by the LED array 394, guided to the light receiving surface of the imaging unit 382 via the SELFOC lens array 390, and read. .

Two magnetic sensors 451 are provided near the entrance and exit of the digitizer 300 in the device main body 400 at positions facing the digitizer 300, and a magnetic coating 300 is provided on the portion of the digitizer 300 facing the magnetic sensors 451.
b is formed.

Therefore, when the digitizer 300 moves, the magnetic sensor 4
51 detects the movement of the magnetic coating 300b and detects the amount and direction of movement of the digitizer. In addition, near the entrance and exit of the digitizer, there is a reflective optical sensor 452.
is placed. This sensor 452 distinguishes between the reflective portion 300c (FIG. 32) provided near the right end of the digitizer and the other portions, and identifies whether or not the digitizer 300 is completely rolled up.

Next, a third embodiment will be described with reference to FIGS. 35 and 36.

The digitizer unit 500 and the display panel 321 are stacked in their thickness direction and are integrally configured. The shaft 412 shown in FIG. 36 is coupled to the drive shaft of an electric motor (not shown) fixed to the main body 400 of the device. A main drive roll 611 made of a rubber material with a large friction coefficient is concentrically fixed to this shaft 412. This main drive roll 6
11 is.

A part of the outer periphery is exposed on the lower surface of the apparatus main body 600, and the drive roll 618 is in contact with another part of the outer periphery to be frictionally coupled. Furthermore, a pinch roll 619 is provided at a position facing the drive roll 618.

Therefore, due to the weight of the device main body 600, the main drive roll 6
11 comes into contact with a document or recording medium placed on the bottom surface of the device, and when the electric motor is driven, the main drive roll 611 rotates, and the device main body 600 moves over the document or recording medium in the sub-scanning direction (Y direction). ). Further, an assembly of the digitizer 500 and the display panel 521 is sandwiched between the drive roll 618 and the vinyl roll 619 and engaged with them. Therefore, when the main drive roll 611 rotates, the drive roll 618 rotates accordingly, and the digitizer 500 and display panel 521 move relative to the apparatus main body 600.

The moving direction of the device main body 600 and the moving direction of the digitizer 500 are opposite to each other, and their moving speeds are the same. Therefore, for example, when the main body of the apparatus moves to the right, the digitizer 500 moves to the left with respect to the main body of the apparatus 600. The digitizer and display panel do not work.

Similar to the second embodiment, the amount and direction of movement of the digitizer 500 are detected by the magnetic sensor 451. A magnetic coating 500b is formed on the surface of the digitizer 500 facing the magnetic sensor 451. Further, the optical sensor 452 detects the reference stop position of the digitizer 600. A reflecting section 600a is provided at the right end of the digitizer 600 at a position facing the optical sensor 452.

In this example, since a flexible display panel 521 and a digitizer drive roll 618 are provided, there is no fear of buckling, and sub-scanning can be performed manually in either the left or right direction. Note that the main drive roll 611 and the drive roll 61
8 have the same diameter.

Next, a fourth embodiment will be described with reference to FIGS. 37 and 38.

The digitizer 700 and the display panel 721 are integrally constructed by overlapping in their thickness direction. The shaft 412 shown in FIG. 38 is coupled to the drive shaft of an electric motor (not shown) fixed to the body of the device. A main drive roll 811 made of a rubber material with a large friction coefficient is concentrically fixed to this shaft 412. A part of the outer periphery of the main drive roll 811 is exposed on the lower surface of the apparatus main body, and a drive roll 818 is in contact with another part of the outer periphery to be frictionally coupled. The main drive roll 811 and the drive roll 818 have the same diameter. Furthermore, a pinch roll 819 is provided at a position facing the drive roll 818.

An assembly of digitizer 700 and display panel 721 is sandwiched between drive roll 818 and vinyl roll 819 and engaged with them. Further, in the vicinity thereof, guide members 816a, 816b and an idler roll Q17a are provided in order to restrict the movement path of the assembly of the digitizer 700 and the display panel 721.

817b is provided.

This embodiment operates similarly to the third embodiment, except that guide members 816a, 816b and idler roll 817a,
817b is the part of the digitizer and display panel that protrudes from the main body of the device to the right.

It is placed close to the document or recording medium placed on the bottom surface of the device. Therefore, when aligning the surface of the digitizer and display panel with the surface of the document or recording medium below, the third
This embodiment has the advantage that parallax is less likely to occur than the embodiment shown in FIG.

In the above embodiment, before recording the Wi image,
Display the image to be recorded on the display panel.

Although the image is aligned with the recording medium, for example, instead of the image to be recorded, it is possible to display visible information such as its outline on the display panel that simply indicates the range of the image. Similarly, alignment can be easily performed. In that case, the number of pixels required for the display panel is reduced. There is an advantage.

[Effects] As described above, according to the invention set forth in claim 1, the range of the image read by the imaging device is arbitrarily designated by the coordinate input device. This coordinate input means has optical transparency, and! Since it is placed, for example, on top of the document so as to face it, the visible image on the document below can be seen through it from above the coordinate input means. Therefore, alignment of the copying device and the document when specifying one image range can be performed extremely easily and accurately. The image of the range specified in this way is read and stored on the storage means. Further, visible information indicating the read image or the range in which the image exists is displayed on the display means. and,
Images on storage means.

The image is printed on any recording medium by the image recording means. The printing position is set based on the position of the display means. In other words, when performing a printing operation, a light-transmissive display means is placed on a recording medium, and a visible display indicating the image to be recorded or its range is displayed on it, and the recording medium underneath is visible through the display means. You can see them together.

Then, an image is printed on the recording medium as visible as possible at that time, so that the alignment of the recording medium and the recorded image can be performed extremely easily and accurately.

Further, according to the invention as claimed in claim 2, since the input surface of the coordinate input means and the display surface of the display means are integrally constructed in such a manner that they overlap, the operability during positioning is further improved. is smaller and the space it occupies can be minimized.

Furthermore, according to the third aspect of the invention, the image read by the imaging means undergoes image processing specified by the image processing means and is stored in the storage means.0 The image processing means performs independent processing for each area. It is equipped with a holding means that can hold parameters, and can perform different image processing for each area.

The area set in the image processing means can be arbitrarily specified using the coordinate input means. This means of inputting coordinates.

It has a light-transmitting property and is placed, for example, on top of the original so as to face it, so that a visible image on the original below can be seen through it from above the coordinate input means. Therefore, when specifying an area for RLI image processing, it is possible to accurately match the position of the area with the image position on the document.
