PURPOSE:To facilitate the alignment of an original and a device at the time of reading an image and the alignment of the device and a recording medium at the time of recording the image by controlling a range of the image to be read by a frame body, and also, viewing it through the frame body, and displaying the information of the read image or the range in which it exists. CONSTITUTION:A range of an image to be read is adjusted by controlling the range of the image to be read by an image pickup means 182 by a frame body 205, viewing an image on an original 10 through the frame body 205, and aligning the frame body 205 and the image on the original 10. In this state, on a display means 121, information of the image which is read in by the image pickup means 182, or a range in which it exists is displayed, an operator can know in which position the read image exists, and also, a position recorded by a print operation is determined, based on a position of the frame body 205 as a reference. In such a way, the alignment of an image read-in area and an original image position and the alignment of a recording medium and a recording image can be executed simply.

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 image, and prints the read image on an arbitrary recording medium. The present invention relates to an image copying device.

[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.

[Problem M to be solved by the invention] In Japanese Patent Application Laid-Open No. 62-62658, the reading range is fixed within the range of a frame, and when copying an image of the same size as the frame, The image 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 the document and device are aligned so that they are aligned. Also,
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 Application 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 ordinary documents. However, since the FM document must be placed face down (upside down) on the reading surface of the device,
In this state, you cannot directly see the positional relationship between the scanning surface and the image on the document, and when you want to copy a part of the document that is larger than the scanning surface, the alignment may be inaccurate, causing the image to protrude, tilt, etc. This will cause inconvenience. Further, the recording medium is limited to a sheet, and it is difficult to align the recording medium and the recorded image.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is 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.

Means for Solving the Problems] In order to solve the above problems, the present invention provides an imaging means that can be placed on any document and reads the document image by decomposing it into pixel units; a frame that can be freely arranged to face the surface of the medium, regulates the range of the image read by the imaging means, and allows the image to be seen through; a storage means that stores information on the image read by the imaging means; It can be freely placed facing the surface of the original or recording medium.
Display means for displaying visible information of the read image III obtained by the imaging means or visible information indicating the range where the read image exists; Image recording means for forming a permanent visible image on any recording medium; and the imaging means and storage means 2
controlling the display means and the image recording means, sending information on the image read by the imaging means to the image recording means via the storage means, and recording it at a position on the recording medium with the position of the frame as the base; Provide electronic control means.

[Operation] According to the present invention, since the range of the image read by the imaging means is restricted by the frame, it is possible to read, for example, an image on a document facing the entire inner part of the frame. Since the image on the document can be seen through the frame, the range of the image to be read can be adjusted by aligning the frame and the image on the document.

Since the display means displays information about the image read by the imaging means or the range in which it exists, the operator can determine the position of the read image without performing a trial printing operation on recording paper. You can find out if it exists.

The position recorded in the print operation is determined based on the position of the frame, so the positional relationship between the position information displayed on the display means and the frame can be used to determine the relationship between the recording medium facing the frame and the recorded image. Positioning can be easily performed.

In a preferred embodiment of the present invention, a light-transmissive display means is used and is placed on a frame.

In this way, it is possible to set a one-to-one positional relationship between the reading range on the original, the recording range on the recording medium, and the area on the display means, and the display means on the recording medium that can be seen through the display means. The image can be printed in the exact position shown. Therefore, poles.

Positioning can be done easily and accurately.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

That is, the first function is an image reading function, which scans the image on the surface of the original (10), sequentially reads the information of the image separated into pixels, and transfers the image data to an external device ( In this example, it is output to a personal computer 90). The second function is an image recording function, which receives image data of characters and pictures input from an external device (personal computer 90 in this example) and saves the image as a permanent image on the recording medium (10).

It is possible to capture an image and read the image data. The image processing terminal device 340 placed on an arbitrary plane (1o) can be automatically driven by a drive mechanism or manually moved on the plane.

- Operates as a dimensional image sensor. The spectral sensitivity of this is approximately -1, that is, panchromatic. This unit is particularly used when reading an original image as high-density monochrome data.

182b is 204 arranged in a row like 182a.
It includes eight image pickup element groups, and furthermore, R (red), G (green j) and B (blue) band-pass optical filters are provided in the light receiving sections of these element groups.

They are repeatedly arranged in the order of R, G, B, R...

Therefore, the three image sensors can read the color information of one pixel separated into R, G, and B, and the image sensor 182b can read the color information of 682 pixels in the X-axis direction.

182c has a group of 1024x1024 image sensors

Therefore, 182c is 341X34 in the X-axis and Y-axis directions.
Color information in a two-dimensional area of one pixel can be read. FIG. 16 shows the structure of this solid-state imaging unit 182c.

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 182e. 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.

It is a servo motor and is equipped with a rotary encoder that generates two-phase signals to identify 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.
93 are combined and the object (1o.

20) is driven to an appropriate position.

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 mounted on the outer periphery of the 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.

The optical system includes a fluorescent lamp 1 used for illuminating the original (10) and backlighting the liquid crystal display panel 121, which will be described later.
It is equipped with 94. The amount of light is automatically adjusted by the MPU 222 controlling the dimming circuit 195 based on the brightness of the image data captured by the imaging module 182.

Referring to FIG. 3, an image processing unit 280 is connected to the output terminal of the image reading unit 180. This image processing unit 280 can be used in various ways! This is a hardware circuit that can perform II image processing and Wi image reading substantially simultaneously in real time, 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.

is applied 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. All of the various image processing parameters are changeable, and are configured so that the MPU 222 can set them arbitrarily.

Therefore, in image processing that involves special image processing, parameters are set such that only shading correction is performed on the image processing unit 280 on the image data read by the imaging module 182, and nothing else is done. After storing data in the image memory 140,
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. Problems tend to occur at points. In such a case, by using software processing that is unrelated to the scanning speed, high-quality scaling processing becomes possible, although the processing speed becomes slower.

8 each include a plurality of sets of processing circuits therein. For these multiple sets of processing circuits.

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 5ELL to 5EL5 are connected to a timing/area signal generation unit 231 via a system bus 221, and the selected states are 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 five-bit read/write memory for storing one 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 to an external device, such as the personal computer 90, via the data bus 221 and the external interface unit 240.

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 character codes 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), 2M (magenta), C (
four inkjet recording heads 161Y of cyan) and K (black).

161M, 161G and 161K are provided.

Referring to FIG. 2, the recording head of each color and the partitioned booth of each color of the ink tank 165 are connected by pipes 162Y, 162M, 162C, and 162, respectively. Each inkjet recording head includes an ink ejection nozzle and a drive circuit. In addition, each recording head has 2048 recording heads arranged in one row in the X-axis direction.
Equipped with several ink ejection nozzles.

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 of 512×512 pixels, and is capable of displaying 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 something 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 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, and displays the read image in the recording stage in the printer mode or copy mode. -The image that will be recorded will be displayed.

In addition, various guidance messages and key switch marks for input operations are displayed on the display panel 121.

In addition to the display panel 121, the display/input crab knit 100 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 28 light emitting diodes arranged in a line in the Y direction and at equal intervals in the X direction. 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 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, so the light blocking object will be placed at that position. can be known to exist. In this example, the photodiode array 103 is positioned on the display panel 121 in the X direction.

The photodiode array 105 can detect the position in the Y direction on the display panel 121 with a resolution of 1/128.
It can be detected with a resolution of 12g. Therefore, the display panel 12
When a finger or the like is brought close to 1, its XY coordinates can be detected. This allows input operations.

Note that the 128 light-emitting diodes are sequentially energized by the light-emitting layer, and only the photodiodes located at positions facing the energized light-emitting diodes are present.

The presence or absence of light reception is determined.

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 about 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. It can also be done.

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, when the display/input crab knit 100 is folded, 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 ball-shaped motor rotor 211 is exposed on the bottom surface of the device body.

Although only one motor rotor 211 appears in FIG. 2, there is actually another motor rotor 201 (third
(see figure). The 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 orbits around two of the three mutually orthogonal coordinate axes (i.e., the X and Y axes). The position of the circumferential surface of the ball is N, surrounding the origin.
The poles and south poles are each magnetized in an alternating cursed pattern.

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, the image processing terminal device 340
3. When energizing 212X, move in the X-axis direction, and when energizing 212Y, move 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 are coated with a material having a low coefficient of friction such as tetrafluoroethylene at the portions that come into contact with the motor rotor.

Around the motor rotor 211, the amount of rotation in the X direction (rotation around the Y axis) and the amount of rotation in the X 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 X 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 these, the image processing terminal device 340 does not generate any rotational movement and always rotates in the X direction or direction. Move linearly in the X direction.

The buttons of switches 253 to 258 shown in FIG.

As shown in FIG. 1, it is exposed at the top of the Sa body. The states of these switches are as required.

MPU 222 reads via I10 boat 230.

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

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

Input data is input to the terminal Din, and processed data is output to the terminal Dout. In FIG. 12, π is a multiplier, aiJ is a coefficient register, DiJ is pixel data, and i and j correspond to the x and y coordinates of a pixel, respectively, and in this example are in the range of 1 to 9. . Therefore, the results of arithmetic processing of a two-dimensional pixel group of 81 pixels are output. The content of the calculation is shown in the following equation (1).

Dout = Σ(aij x Dij)...
(1) Each of the 81 coefficient registers aij is an 8-bit latch, and the coefficients held therein can be arbitrarily set by the MPU 222 via the system bus 221. By changing the coefficients, the characteristics of this filter can be set arbitrarily. In this example, as shown in FIG. 6, the spatial filter unit 281 is provided with a plurality of filters in parallel, so each filter is used for smoothing, edge enhancement (blur improvement), etc. ; Suitable characteristics can be set, and different processing results can be obtained at the same time. However, among those processing results, the actual gamma correction unit 28
2 is limited to only one selected by the selection circuit 5ELL at that time.

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, part of the same image is smoothed and the other part is sharpened. This operation becomes possible. The timing/area signal generation unit 231 outputs an instruction to the selection circuit 5ELL.

The gamma correction unit 282 should also include multiple sets of correction circuits. As is conventionally known, gamma correction is a method of changing image density, for example, making the background part of an 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. Out of the plurality of sets of correction circuits, one output selected by the selection circuit 5EL2 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, similar to the aforementioned 5ELI.

The configuration of one set of correction circuits of the color correction unit 283 is as follows.
As shown in the figure. Referring to FIG. 13, the input data is R, G.
and B are separated into terminals D 1 v D
2 and D3, and the results of the processing appear on four sets of terminals Do1 to Do4, separated by color. In FIG. 13, π is a multiplier, Σ is an adder, akij and bk
i is a coefficient register. The contents of the coefficient register akij can be set to any value by the MPU 222 via the bus 221.

Furthermore, a plurality of sets of coefficient register matrices are arranged, and it is possible to dynamically select which one of them is 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 original 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 next circuit performs magnification in the sub-scanning direction (Y direction). The circuit shown in FIG. 14 performs interpolation of pixels caused by enlargement or thinning out of unnecessary pixels caused by reduction.

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

The input image data follows in chronological order.

Dixl , Dix2 , Dix3 , Dix4 (
x is one of the three types of input), the value of the coefficient register selected is asl, as2. as3. as4 (
s is 16 selection types), the content of the process is as shown in equation (2) below.

Do= Σ Bsj 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 of the processing results is selected by the selection circuit 5
It is selected at EL5 and applied to the next stage trimming unit 287.

Further, the trimming unit 287 outputs a signal from the timing/area signal generation unit 231 that indicates the division of the area and blanks the input data (converts it to data equivalent to white) for the specified area.

In FIG. 10, the timing/area signal generation unit 231
Fig. 7, Fig. 8, and Fig. 9 show the timing of its main signals. First, refer to FIG. 1O.

An oscillator osc generates a basic clock CLKOtt.

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 each 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 during which this signal is H indicates the effective period of main scanning. During that period, CLKB
2048 R pulses appear.

RVGATE is a gate signal in the sub-scanning direction of the image pickup module/L/182 (7) reading scan, and while it is at H, LSYNC pulses appear in the same number 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.

W[1VGAT[E, WCVGATE and lIIMV
GAT[E is for the recording head 161 and 161, respectively.
This is a signal that regulates the recordable period of G, 161M, and 161Y.

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, ink ejection of C, M, and Y inks starts delayed by tl, t2, and 13 hours, respectively, compared to 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.

The counter XCI counts pulses generated for each pixel to generate X@force direction scanning position information, and the counter Y01
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 has AO to
It is a read/write memory in which one word located at one address is composed of 64 bits, and its contents are transmitted via the system 11 bus 221.
The MPU 22.2 can be arbitrarily rewritten. Each word consists of the upper 12 bits du (duo~dun
), the middle 12-bit part d m (d m O=
d m n ) and the lower 40 bit part dρ (d
ρO−dΩn), 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 dQ memory is allocated to selection signal data. Furthermore, 40 bits of dQ are selected by selection circuits 5ELL, 5EL2, 5EL3, 5EL.
Six bits are allocated to each of 4 and 5EL5, and the remaining 10 bits are allocated to trimming unit 287.

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 it is possible to set relatively large images. 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.

In addition, the data of each lard 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 (AO~
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 the result of the comparison between the value read from dm of area memory AM (X-direction area position) and the scanning position in the X-direction by comparator 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 scanning position match. , thereby updating the address designation of area memory AM.

That is, the contents of the area memory AM are read out in order from addresses AO to An as the image reading scan progresses. Every time the read address of the area memory is switched, the data output to the 1 selection circuits 5ELL to 5EL5 and the trimming unit 287 is changed, so the content of image processing is 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 an aborted state (step PI) so that it 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, it is sufficient to close the 1 display/input crab knit 100 to the state shown by the dashed line in FIG. In that case, the magnetic sensor 251 issues an interrupt signal to the interrupt controller 226, and the interrupt controller 226 applies an interrupt signal to the MPU 222 in response. 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 1 display/enter crab knit 100 is closed while the button of the switch 258 is pressed, transition to the halt state is prohibited. In this case.

Display/Enter 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 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 transferred to the display memory after thinning out a predetermined number of pixels. Write to 127. Display memory 1
The image data written on 27 is transferred to LCD drive 1.
26 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 contents of the display screen on the display panel 121 at the end of step P5 are, 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, it becomes as shown in FIG.

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 (10) 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 under the display/input crab knit lOO
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 2. In this example, there are still more 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 the movement of the device, it controls the data in the display memory 127 according to the amount of movement, scrolls the image 121b displayed on the display panel 121 toward the opposite side of the direction of movement of the device, The contents of the remaining undisplayed image data are displayed in the area on the display panel that has become newly capable of displaying images.

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, and the display panel 12
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 and image 121b displayed on the display panel 121 and the pattern 10c 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 original 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 displayed. It is possible to accurately check whether the print image (10c) on the recording medium is aligned with the print image (10c).

If the positions are not correct, it is sufficient to lift the W image processing terminal device from 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 Since the rotors 201 and 211 do not 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 image processing terminal device manually.

As mentioned above, since the motor rotor can be driven, it is also possible to make the device run on its own.

Although the explanation has been given here regarding the vertical direction (Y-axis direction) of the display panel, the displayed image is similarly scrolled in the horizontal 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, the process proceeds to step pH, step Pi.
At step t, print specifications and data of the image to be printed are received. The received data is then written to the image memory 140. When the data reception and writing to the memory are completed, the next step P12 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 characters are received as code information, the font memory 232 is used to convert the image data into The bit pattern of the character corresponding to is expanded 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 PI3, the bit pattern image data existing on the image memory 140 is written into the display memory 127. This writing is performed at high speed using DMA.

At the end of step P13, the display on the display panel 121 becomes, for example, as shown in FIG. 19 or 20 described above. 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.

One image is displayed on the display panel 121 in the 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 1 display screen is pressed.
Waits for an input operation to be performed on .

If there is an input, the process advances to the next step 16.

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

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 in the Y-axis direction along the surface of the recording medium, and the recording axis of the black recording head 161 moves to the top position of the displayed image before the device moves ( In Fig. 20, the upper part of 121a with broken line)
Position it so that it aligns with the 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 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, 161C, 161M, and 161Y, and a constant speed running command in the Y direction to the main drive unit 214, respectively. Output via bus 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
, 161G, 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 the recording of one line is completed, the image processing terminal device moves by one pixel in the sub-scanning direction and starts recording the next one line.

During this recording operation, the image to be recorded is displayed on the 1 display panel 121, and the displayed content 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 position recorded at that time on the five images.

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, applied scan specification data 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. For example, it executes setting of various processing parameters of the image processing unit 280, setting of area memory contents of the timing/area signal generation unit 231, and the like.

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. If the simplest scan specification is set, in which the entire range of the display surface of the display panel 121 is read, the positions of the images to be read on the document are set in m so that they fall within the display surface of the display panel. All you have to do is match it up.

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 the display panel match.

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 a document (10) 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 shows that the reading range is expanding further to the right (X direction) than the display range, and 121ay indicates that the reading range is further expanding in the direction below the display range ( This indicates that the reading range is expanding in the Y direction). Further, 121g is a mark indicating 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, tone of density gradation, two tones, image displacement, dither pattern, etc. with respect to other areas. These image processes are performed in real time by the image processing unit 280 at the time of image reading.

There are cases where a scan specification is set in which the reading range is arbitrarily designated.6 In that case, the MPU 222
223 as fixed area shape data, and a pattern existing as user-defined area shape data on the RAM 224.

It is displayed on the display panel 121. In that case 5 for example the second
A screen like the one shown in Figure 7 will be displayed.

In FIG. 27, 12Li, 121j, 121k, and 121Q are fixed area-shaped patterns, and 121n is a user-defined area-shaped pattern. 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. Note that when specifying an area such as 121 m, 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, 1, for example, by moving the fingertip so as to draw a locus of a required 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 area set in this way can be registered in the RAM 224 as a user-defined area shape and used again later.

Regarding the area shape pattern soft key, if another key 121e is inputted before performing the second input operation, the picked up area pattern is rotated by 15 degrees.

For example, the area shape pattern 121b is the pattern 121
After picking up 12, press soft key 121e to 6.
Input operations.

Obtained by rotating 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 that will be set when the 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 input range of the display/input unit lOO, 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 pt is input in the state shown in FIG. 19a.

That is, the user touches the position of Pl 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 moves from the point pi to the line segment indicating the range of the area toward the unyielding half area. Marks 121ax +121ay are drawn.

After that, when the operator moves the image processing terminal while keeping it in contact with the document, both sides are displayed, for example, as shown in FIG. 29b. Note that 10a in FIG. 29b is a printed pattern on the original. Next, when point P2 shown in FIG. 29c is input, the display on one screen changes as shown in FIG.
y 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, the position of the image processing terminal device is returned to the initial state, the screen shown in FIG. 29a is displayed, and in this state, two points P3+P4 are manually entered. Next, move the device again and select one point P5 on the screen shown in Figure 29c.
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 121s 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 1 display panel 121. When this screen is displayed, the image processing content within the designated area can be interactively selected. After this operation, the user can return to the original screen state by inputting a screen return soft key displayed on that screen. If the soft key for starting reading is input, the reading operation can immediately proceed to the next step P26.

Note that ji! is inside the area to be trimmed. It is also possible to set a special area for IF image processing.

In step P25, the software waits for an input operation on the soft key 121h, and if there is an input, the process proceeds to step P26.

In step P26, the image is actually read according to the scan specifications set in the processes up to that point. What is important here is that no positional deviation occurs between the designated reading position and the position of the image that is actually read.

Specifically, when no special reading area is specified, the inner part of the display/input unit's display/input area and the area on the document that was facing during alignment. When it is important to read the image and a reading area is specified, the image of the area of document 1 that is opposite to the rectangular frame indicating the reading range displayed on the screen during alignment is read. This is important, and if there is a special area designated for further cropping or image processing in the scanning area, the image of the area on the document that is facing the frame indicating the range of that area, It is to perform trimming and image processing without causing positional deviation.

In this embodiment, at the time of positioning, the printed image of the document "2" and the display such as a frame indicating the area on the display panel 121 appear to overlap, so the positioning is accurate, and from that point on, the image is actually read. Unless there is a slip between the device and the document, there is no risk of misalignment.

When the size of the set reading area is equal to or smaller than the size of the display panel l21, the MPU 222 determines that the conjugate point between the imaging unit 182a and the lens 190 is
The edge of the display panel 121 in the sub-scanning direction (121 in FIG.
A movement amount is given to the main drive unit 214 to move it to the position (above).

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
A movement amount is given to the main drive unit 214 to move it to the position 121 a x) in the figure.

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 designated movement 1jJffi, 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 11 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 of a and 182b has 2048 pixels 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 for each main scanning line in synchronization with the signal LSYNC, and one pixel interperiod signal CLKBR is used for each line.
2048 pixels are sequentially read in synchronization with . The read data is subjected to image processing by one 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, 1 word is 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. Further, 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. Therefore, without waiting for the scanning of the entire reading range to be completed, it is possible to read only a portion of the image that has been scanned.

The operator can immediately view and confirm the reading results. 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 La, 121b, and 121m. In this condition.

When an input operation is performed on the soft key 121h, image reading is started. As a result, the screen shown in FIG. 28 will be displayed. Comparing FIG. 27 and FIG. 28, the frame 121a
, 121b, and 121m are extracted as valid image data. Note that the frame 121a.

The information 121b and 121m is stored in the RΔM 224 and is 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, 10c,
10d 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 100 alobs on the original.

In the example shown in FIG. 31a, an arbitrary designated command is received from the personal computer 90, and the operator sets different image processing to be performed 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, reading of one image is started, and as a result, the
The screen shown in Figure b is 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 to make the device move by itself. When self-propelled, power consumption is large.

In a situation where an image processing terminal device uses a battery as a power source and cannot obtain power from a host computer, the usable time of the device is greatly limited.

Therefore, if it is desired to reduce power consumption, the device 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 file mode is entered and the process proceeds to step P31. In this step, a menu screen is displayed on the display panel 121 to wait for instructions from the operator regarding file operations. This menu screen displays images from disk 80 to image memory 1.
Information for selecting whether to transfer the image data to the image memory 140 or to transfer the 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 is checked for the two soft keys (save and load) displayed on the display panel 121, and if there is an input to save, the process advances to step P34, and the input to load is input. If there is, 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 +40 after data decompression processing.

Next, the case of copy mode will be explained. There are two types of copy modes. One is a mode in which one image processing terminal device is used, and the other is a back-to-back mode in which two image processing terminal devices are used. When the wired interfaces 242 of two image processing terminal devices are connected to each other with a cable, it is
, and 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 the back-to-back mode, one side performs the reading operation and the other side simultaneously performs the printing operation. In back-to-back mode, one side is in scanner mode,
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, 121d is sharpness adjustment, 1
21e 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, the processing that can be selected for each step of the image processor, for example, in the gamma correction processing step, high contrast, low contrast, A selection menu appears in the form of high keys and low keys, 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 the gradation can be set to any characteristic 121adj from the standard characteristic 121st by touching the touch marks 121adj+, 121adj-, and 121adjs. can. 1211 is a soft key for returning to the original screen (FIG. 11a); 121b 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 1 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 in each main scan is processed by the image processing unit 28
0, the image is processed, converted into recording data, and stored in the image memory 140. At the same time, the MPU 222 calculates data suitable for one display, and the display memory 127
written to.

Step P61 is a process for executing a print operation, and for example, a screen shown in FIG. 22 appears. 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 as the image displayed on the display panel 121 is recorded on the recording medium directly below the display position. Again, what is important is that what is seen by the operator on the display means is recorded as a permanently visible image on the recording medium.

Therefore, for example, if the recording medium has a preprint such as ruled lines in advance, the recording position can be appropriately aligned. The position is to lift the table 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 menu screen are keys for re-image processing, and when these keys are touched, a menu screen for re-image processing appears. 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), it is not necessary to read the original image repeatedly, so you can reuse the image data on the image memory 140 and read it again. processed by the image processing unit,
Output the processing results 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 2
Gradation adjustment, density adjustment, nine-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, timing and
Data is written to the area memory of the area signal generation unit 231. Thereafter, the DMA controller 225 inputs a predetermined address in the image memory 140 as the transfer source address and the image processing unit +-28 as the transfer destination address.
The addresses of the 0 multiplexers 289 are respectively set to execute DMA data transfer. As a result, one image data is subjected to image processing again and displayed on the display panel 121 again.

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 overlapped with each other. 100, it is possible to relatively easily align the image range to be processed with the document or recording medium without making the display/input unit 100 transparent. I can do it. In that case, for example, an opaque EL display device may be used as the display means. If an 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 shown in FIG. 32. Similarly, FIGS. 35 and 36 show the image processing terminal device in the third embodiment, and FIGS. 37 and 38 show the fourth embodiment.
1 shows an image processing terminal device according to an embodiment of the present invention. Also the 34th
The figure shows a block diagram of a device configuration that is substantially common in the second, third, and fourth embodiments.

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

(1) Each color function of image reading, 2-image display, 2-image recording,
The V&image function of the three-dimensional object, the autofocus function and the floppy disk drive are omitted.

(2) A digitizer device for inputting coordinates is constructed by arranging a large number of pressure-sensitive electrical contacts within a flexible and transparent film l-. Further, as a display device, a light-transmissive liquid crystal display panel formed in the shape 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 relative to the original or the recording medium. Therefore, images and the like 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 CCD.

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, and is equipped with 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 is done in monochrome.

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, with a thin transparent insulating film sandwiched between them. It is glued with. 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 controlled by a detection control circuit 306, and data of detected coordinate values is transmitted via the system bus 221.
It is transferred to the MPU 222.

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. A drive shaft of an electric motor (not shown) is coupled to the shaft 412 shown in FIG. 33. 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 this 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, and the main body 400 of the apparatus is driven in the sub-scan direction toward the right. In addition, with one end 300a fixed,
The device main body 400 can also be moved to the left side by manual operation. 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. Further, a reflective optical sensor 452 is arranged near the entrance and exit of the digitizer. 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 rubber material with a large coefficient of friction is concentrically fixed to this shaft 412. This main drive roll 611 has a part of its outer periphery exposed on the lower surface of the apparatus main body 600, and a drive roll 618 on the other part of the outer periphery.
are in contact and are frictionally connected. In addition, the drive roll 618
A pinch roll 619 is provided at a position facing the.

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, the assembly of the digitizer 500 and the display panel 521 is sandwiched between the drive roll 618 and the pinch 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 driving 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 618
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.

The assembly of the digitizer 700 and the display panel 721 is sandwiched between the drive roll 818 and the pinch roll 819 and engaged with them. Further, in the vicinity thereof, guide members 816a, 816b and an idler roll 817a 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, the portions of the digitizer and display panel protruding from the apparatus main body to the right are placed close to the document or recording medium placed on the bottom surface of the apparatus. Therefore, this embodiment has the advantage that parallax is less likely to occur in alignment between the surface of the digitizer and the display panel and the surface of the document or recording medium underneath than in the third embodiment.

In the above embodiment, before recording an image, the image to be recorded is displayed on the display panel and the image is aligned with the recording medium. Even if you change the display panel to simply display visible information such as its outline indicating its range,
Similarly, alignment can be easily performed. In that case, the number of pixels required for the display panel will be reduced.
There is an advantage.

[Effects] As described above, according to the present invention, the range of the image to be read by the imaging means is regulated by the frame, so 1. For example, an image on a document facing the entire inner part of the frame cannot be read. Can be done. Since the image on the document can be seen through the frame, the range of the image to be read can be adjusted by aligning the frame and the image on the document.

Since the display means displays information about the image read by the imaging means or the range in which it exists, the operator can determine the position of the read image without performing a trial printing operation on recording paper. You can find out if it exists.

The position recorded in the print operation is determined based on the position of the frame, so the positional relationship between the position information displayed on the display means and the frame can be used to determine the relationship between the recording medium facing the frame and the recorded image. Positioning can be easily performed.
