In the image reading device 1O configured as described above, when the image reading device 10 is set on the document 44 to be read after completing various procedures for operation and is manually moved over the document 44, the image reading device 10 is moved in response to the movement. The transfer roller 41 rotates,
In synchronization with this, the rotation angle is detected by the encoder formed by the slit disk 40, the first photointerrupter 45, and the second photointerrupter 46, and this signal is sent to the control circuit section 5.
5 is output. At the same time, the light source 42 is also turned on, and the reflected light from the irradiated document 44 forms an image on the image sensor 51 via the lens 5o, undergoes photoelectric conversion, and is input to the control circuit section 55 as analog image data. . The control circuit unit 55 controls the image sensor 51, the first photointerrupter 45, and the second photointerrupter 46 mounted on the control board 47 and the control board 52,
A DIR signal, which is an output signal, is generated on the signal line 22, a start signal is generated on the signal line 23, an image information signal is generated on the image data signal line 24a, and a data clock is generated on the signal line 24b. generate. Further, the first switch 53 and the second switch 54 respectively output an image signal on/off signal and a reading range switching signal ("0" level when the switch is turned on, and "1" level when the switch is turned off) to the signal line 27. is generated on the signal line 26. These signal lines 22, 23, 24a, 24b, 26, 27 and a power supply line 25 that supplies power to the image reading device 10 are connected to the image reading control circuit 9 of the main control circuit via a cable 21. .

Next, the configuration and operation of the control circuit section 55 will be explained using FIG. 4. The control circuit 55 includes a binarization circuit 57, a moving direction detection circuit 58, a start signal generation circuit 59, and a data clock generation circuit 60. The analog image data output from the image sensor 51 is processed by the binarization circuit 57. After A/D conversion, it is converted into a serial digital signal and output as image data onto the signal line 24a.

The first detection signal and the second detection signal, which are two signals with a phase difference output from the first photointerrupter 45 and the second photointerrupter 46 to the signal lines 61 and 62, are output from the movement direction detection circuit 58 and the start It is input to a signal generation circuit 59 and a data clock generation circuit 60.

The moving direction detection circuit 58 generates a DIR signal indicating the moving direction of the image reading device 10 on the signal line 22 from the first detection signal and the second detection signal.

The start signal generation circuit 59 generates a start signal, which is a synchronization signal for indicating a valid period of image data for each movement unit of the image reading device 10, into a rotation angle detection signal of the encoder (specifically, a first detection signal). and the second detection signal) and output it onto the signal line 23. Therefore, although the generation cycle of the start signal depends on the moving speed of the image reading device 10, the data valid period after generation is constant.

The data clock generation circuit 60 generates a data clock, which is a transfer lock for transferring image data, on the signal line 24b from the first detection signal and the second detection signal.

5(a), (b), and (c) show the configuration and operation of the moving direction detection circuit 58. FIG. 1st
The relative positional relationship of the photointerrupter 45 and the second photointerrupter 46 is set to a certain constant value in order to obtain a first detection signal and a second detection signal having an output phase difference φS.

FIG. 5(a) shows the waveforms of the first detection signal and the second detection signal when the transfer roller 41 rotates in the normal direction. Since the first detection signal temporally leads the second detection signal by the phase φS, the state of the second detection signal is always at the "o" level at the rising edge of the first detection signal.

FIG. 5(b) shows the waveforms of the first detection signal and the second detection signal when the transfer roller 41 rotates in reverse. In this case, the first detection signal has a phase φS with respect to the second detection signal.
is delayed by a corresponding amount of time.

Therefore, the state of the second detection signal is always at the "1" level at the rising edge of the first detection signal.

FIG. 5(C) shows a moving direction detection circuit 58 configured to logically process the two detection signals shown in FIGS. 5(a) and 5(b) to detect the moving direction of the image reading device 10. It is a block diagram. With this circuit, the DIR is at the "0" level when the transfer roller 41 rotates in the forward direction, and at the rlJ level when the transfer roller 41 rotates in the reverse direction.
Generate a signal. Furthermore, the reset signal in the figure is a signal necessary for initializing the circuit.

FIG. 6 shows the relationship between the moving direction of the image reading device 10 and the rotating direction of the transfer roller 41.

When the document 44 is moved in the forward direction as shown in the figure, the transfer roller 41 rotates in the forward direction and the DIR signal becomes the rQJ level. Furthermore, when the transfer roller 41 is moved in the opposite direction, the transfer roller 41 rotates in the opposite direction, and the DIR signal becomes the "1" level.

The output timings of the DIR signal, start signal, image data, and data clock will be explained with reference to FIGS. 7(a) to 7(d).

The start signal reads the rotational movement angle of the transfer roller 41 using an encoder, and is output as a positive pulse when a predetermined angle change occurs. Therefore, its output period T s
p depends on the moving speed of the image reading device 10 on the original 44; that is, when the moving speed is high, Tsp is short, and when the moving speed is low, Tsp is long. The image data and data clock are output only during the T1 period after the start signal is generated, and the data clock functions as a synchronization clock for transferring the image data. Time T1 is the data validity period, but this depends on the number of pixels read by the image sensor 51, - T1 = (number of image sensor pixels)
It can be expressed as × (transfer lock period). The DIR signal becomes rQJ or "1" level in synchronization with the generation of the start signal, and notifies the outside of the rotational direction of the transfer roller 41 at that time.

Next, the configuration and operation of the image reading control circuit 9 having an interface function between the image reading apparatus 10 and the main body will be explained using FIG.

The image reading control circuit 9 stores status information of the image reading control circuit 9, and the CPU 1 stores the status information of the image reading control circuit 9.
0, a second register 71 that can write control signals, and serial image data input from the image reading device 10 to the CPU.
A data conversion circuit 76 converts the data into parallel data so that it can be read.
A third register 72 that can be read by monitors the start signal and determines the valid period of image data after the start signal is generated (
a reading start detection circuit 74 that detects the T1 period) and outputs a start detection signal indicating the period on the signal line 78;
Additionally, similarly, the start signal is monitored, the moving speed of the image reading device 10 is calculated from the input cycle (the number of inputs per unit time) of the start signal, and the calculation result is compared with a preset reference speed. The image reading device 10
It is composed of a start pulse monitoring circuit 73 which detects the moving state of the motor and outputs a state signal "1" on the signal line 77 when the motor is moving, and "0" when the motor is stopped. This start pulse monitoring circuit 73 can be realized by hardware using a retriggerable multivibrator or the like, or by a CPU having software that executes the signal processing as described above. Reference numeral 75 is a counter that counts the data clock on the signal line 24b, and a data storage completion (RE) indicating that data storage has been completed (in this example, 3 bits) in the third register 72 is indicated.
Q) Generate a signal on the signal line 79 and connect the data conversion circuit 76
A latch clock signal for transferring the image data converted into serial data to the third register 72 is generated on the signal line 8o. Also, a first switch level detection circuit 85 detects the level of the image signal on/off signal on the signal line 27, which is the output signal of the first switch 53, and outputs a read prohibition signal on the signal line 82; 2 switch 5
A second switch level detection circuit 86 is provided which detects the level of the reading range switching signal on the signal line 26, which is the output signal of No. 4, and outputs a range signal on the signal line 83. The buffer 81 is a circuit that controls whether or not to input any signal among the DIR signal, start signal, and image information signal to the internal circuit of the image reading control circuit 9, and uses the control signal to prohibit reading on the signal line 82. A signal is used.

Specifically, when the first switch 53 is on, the read inhibit signal on the signal lines 8 and 2 goes to "O" level, the buffer 81 becomes inactive, and the DIR signal,
Some of the start signals and image information signals are not input, and no image reading operation is performed. Conversely, when the first switch 53 is off, the read inhibit signal on the signal line 82 is at the "1" level, the buffer 81 is activated, and an image reading operation is performed.

Next, the configuration of the first register 70 will be explained.

The DIR bit is set or reset depending on the level of the DIR signal. Specifically, the image reading device 1
When the moving direction of 0 is the forward direction/reverse direction, the transfer roller 41
rotates forward/reversely, the DIR signal indicates "0 level"/"Level", and at this time the DIR bit is rOJ/r
It becomes lJ. This data can be read by the CPU, and the CPU can know the rotational direction of the transfer roller 41 and the movement direction of the image reading device 10 by reading the DIR bit data. Also, C.P.
The DIR bit data read by the UI is stored in the DIR flag area 109 in the program memory 2. The status bit is set or reset depending on the level of the status signal on signal line 77. Specifically, when the moving speed of the image reading device 10 is smaller than a predetermined value, that is, close to a stopped state, the value is "0", and when the moving speed is higher, the value is "1". And this data is CPU1
By reading the status bit data, the CPU can know the movement status of the image reading device 10. Start detection bit is signal line 7
It is set or reset according to the level of the start detection signal on 8. Specifically, it is "0" during the valid period (T1) of the image data and data clock, and is "1" during the other periods.

The CPUI can thereby know the validity period of the image information signal. The REQ bit is connected to the REQ bit on signal line 79.
Set or reset depending on the signal level.

The REQ signal converts the serially received image data to the number of bits in the third register 72 (8 bits in this example).
When data is extracted according to the data, it functions as a completion signal for the extraction. Specifically, it becomes "1" when the setting of the data to be read by the CPUI is completed in the third register 72, and it becomes "0" from the time when the CPUI reads the data until the next new read data is set.
”. The range bit is set or reset depending on the level of the range signal on signal line 83. Specifically, when the second switch 54, which has the function of indicating an area where image reading is not required when pressed, is on, the reading range switching signal becomes rQJ level, and this is transmitted to the range bit as a range signal. Further, when the second switch 54 is off, the reading range switching signal becomes "1" level, and the range bit becomes "1". At this time, the CPUI reads the range bits via the pass line 20 to
It is possible to know whether the image reading device 10 is in the image reading area or in the image reading unnecessary area at that time.

The second register 71 is a register that can be written to by the CPUI. The initial bit of the second register 71 outputs an initial signal onto the signal line 84 when data is written by the CPU '1. This initial signal is input to the start pulse monitoring circuit 73, the reading start detection circuit 74, the counter 75, and the data conversion circuit 76, and instructs the initialization of each circuit.

The third register 72 is a register readable by the CPUI, and functions to store the image data converted by the data conversion circuit 76 and interrupt the image data to the CPUI.

9(a) to (C) show the direction of displayed characters on the liquid crystal display device 8 that displays image data read by the image reading device 10, and the data arrangement of the image processing work memory 4 and the display work memory 6. It shows the mutual relationship between FIG. 9(a) shows the direction of characters displayed on the liquid crystal display device 8, and FIG. 9(b) shows the direction of characters displayed on the liquid crystal display device 8.

(C) shows in which arrangement data should be written to each memory in order to display the display shown in FIG. 9(a). Each memory array is defined with the flow from left to right and from top to bottom in the display as a forward direction, and the direction opposite thereto as a reverse direction. Here, the CPU 1 is the image reading device 10
The image data transferred from the image processing section 4 is stored in the image processing work memory 4, and is also transferred to the display work memory 6 for execution of display processing. The data transferred to the display work memory 6 is displayed on the liquid crystal display device 8 by the display operation of the liquid crystal controller 7.

Next, among the programs executed by the CPUI, an image reading processing program that includes the features of the present invention and is stored in the program memory 2 will be described with reference to FIG.

The image reading processing program is executed by inputting a function selection from the keyboard 15, stores the image data read by the image reading device 10 in the image processing work memory 4, and at the same time writes the data in the display memory 6. The screen is displayed on the liquid crystal display device 8.

Processes 90 to 95 represent pre-processing for the image reading operation. Processing 90 is carried out by the image reading control circuit 9
This initializes the internal circuitry of the second register 71 by writing data into the second register 71 and setting the start pulse monitoring circuit 73, read start detection circuit 74, counter 75, and data conversion circuit 76 to their initial states.

Process 91 is to have the operator input the direction of the read image from the keyboard 15. For example, if the read image is in the vertical direction with respect to the display screen, specify vertical reading, and if the read image is in the horizontal direction, input the horizontal direction. Specify direction reading. When vertical reading is specified, the CPUI stores data in the image processing work memory 4 and the display memory 6 in a vertical direction with respect to the display screen, and horizontal reading is also specified. and the CPUI store data in the image processing work memory 4 and the display memory 6 in a direction horizontal to the display screen.

Process 92 detects the start of the image reading operation, and continues to be executed while the start detection bit of the first register 70 is "1", and moves to process 93 when the detection bit becomes "O". .

Process 93 detects the moving direction of image reading device 10, and is specifically executed by reading and rechecking the DIR bit of first register 70. As a result, D.I.
If the R bit is rQJ, the process goes to process 94, and if it is "1", the process goes to process 95.

Process 94 is executed when the DIR bit is rQJ in process 93, and resets (=O) the DIR flag area 109 on the program memory 2 to remember that the moving direction of the image reading device 10 is the forward direction. .

Process 95 is executed when the DIR bit is "1" in process 93, and resets the I0R flag area 109 (=1) to store that the moving direction of the image reading device 10 is the reverse direction.

The actual image reading operation is performed in steps 96 to 103. In process 96, the REQ bit of the first register 70 is checked, and the image is transferred from the data conversion circuit 76, which converts the image data serially inputted from the image reading device 0 into parallel read data, to the third register 72. Determine whether the data transfer is complete. REQ
While the bit is "O", the process 96 continues to be executed, and the RE
The process moves to the next process 97 only when the Q bit becomes "1".

In process 97, the image data stored in the third register 72 is transferred to the internal register (
(not shown).

In process 98, the image data taken into the internal register in process 97 is stored in the image processing work memory 4. When storing, the operator presses the keyboard 1 in process 91.
The direction of the read image designated from step 5 and the DIR flag set in step 94 or step 95 are referenced. When the direction of the read image is specified as vertical in process 91, when the DIR flag is "O", data is stored in the image processing work memory 4 in the upper or lower position relative to the display screen.
= from bottom to bottom; when the DIR flag is "1", storage is from bottom to top. In addition, when the direction of the read image is specified as horizontal, and the DIR flag is rQJ, data is stored in the image processing work memory 4 from left to right with respect to the display screen, and the DIR flag is set to "1". When , storage is from right to left.

In process 99, similarly to process 98, in process 97 the CPU
The image data imported into the internal register of the display memory 6
Store in. When storing, the direction of the read image specified by the operator using the keyboard 15 in process 91 and the DIR flag set in process 94 or process 95 are referred to.

When the direction of the read image is specified as vertical in process 91 and the DIR flag is rQJ, the display memory 6
Data is stored in the display screen from top to bottom, DIR
When the flag is "1", storage is performed from bottom to top. In addition, when the direction of the read image is specified as horizontal, D
When the IR flag is rQJ, data is stored in the display memory 6 from left to right with respect to the display screen, until the DIR flag is "1".
”, it is stored from right to left. Due to this storage, screen display is also performed at any time.

In process 100, the image reading device 1 after starting the reading operation
The operation stop point of 0 is detected with reference to the status bit of the first register 70. If the status bit is rQJ, it is assumed that the moving speed of the image reading device 10 is close to O and the image reading device 10 is in a stopped state, and the process proceeds to step 101. If the status bit is "1", the image reading device 10 is moving at a speed higher than a certain value, and the process moves to process 103 for determining whether to continue the reading operation.

Process 101 is executed when a stop point is detected in process 100, and the position information of the stop point with respect to the display screen is written into the image processing work memory 4.

In process 102, positional information of the stopping point with respect to the display screen is written into the display memory 6. The position information of the stopping point stored in the memory in process 101 and process 102 is processed in process 106.
Alternatively, it is referred to in process 107 and used for image data processing.

Process 103 is to determine whether a series of image data reading operations have been completed, and the processes from process 96 to process 103 are repeated a predetermined number of times, which is set corresponding to the reading length inputted in advance from the keyboard 15. If the execution is completed, the process moves to process 104, and if the execution is not completed, the process moves to process 96.

In processes 104 to 108, processes 96 to 10
3. In the image reading operation, a data confirmation process is executed to finally classify the image data stored in the image processing work memory 4 and the display memory 6 into necessary data and unnecessary data.

Processing 104 selects the data confirmation processing mode from the keyboard 1.
The operator is allowed to make a selection based on the input from 5. There are two data confirmation processing modes: a manual mode in which the operator operates the keyboard while looking at the display screen, and an automatic mode in which the CPU 1 automatically performs the processing according to a predetermined algorithm.

In process 105, branch processing to the data confirmation processing mode specified in process 104 is performed. If the manual mode is specified, the process moves to process 106, and if the automatic mode is specified, the process moves to process 107.

Processes 106, 108, and 110 indicate execution processes in the data confirmation process manual mode, and are shown in FIGS.
This will be explained with reference to (e). FIG. 10(a) shows an example of a read image. In process 91, the read image direction is set to the horizontal direction, and in process 93, the image reading device 10
It is assumed that the direction of movement (direction of the arrow in FIG. 10(a)) is detected as the forward direction. FIG. 10(b) shows the moving speed of the image reading device 10, which is moving while performing a reading operation, in association with FIG. 10(a). Time TO9Tl, T2. At T3, the moving speed is approximately O, and the status bits at that point are shown in Figure 10 (C
), it is at the "0" level, and in other sections it is at the "1" level.

In process 106, the read data is displayed on the screen, and the stopping point detected in process 100 and stored in the image processing work memory 4 and display memory 6 is displayed on the liquid crystal display device 8 as a boundary line of the image block. An example of the screen is shown in FIG. 10(d).

The border line divides the display screen into a first block 120, a second block 120, and a second block 120.
The first block 121 and the third block 122 are divided into three parts.

In process 108, the operator is asked whether data is necessary for each block divided and displayed in process 106. The operator selects and instructs from the keyboard 15 whether the read image data is to be ultimately retained as information processing data or discarded as unnecessary data in units of blocks, according to the operation instructions on the screen. In the example of Figure 10, the first
The block 120 and the second block 121 are selected as unnecessary data, and the third block 122 is selected as necessary data.

Process 110 is a process in which the operator confirms the result of process 108, and blocks selected as unnecessary data are displayed in reverse video to prevent operational errors.

Process 107 is for executing an automatic mode of data confirmation processing, and in this example, the final block is automatically selected as confirmation data using an algorithm previously stored in the program memory 2. Other automatic determination algorithms include a method of determining the block with the longest block boundary interval, and a method of displaying the read image data on the screen while moving the image reading device 10 in a certain direction, turning around at a certain point and then moving in the opposite direction. There is a method to determine the part corresponding to the distance traveled. In this case, the change in the moving direction of the image reading device 10 can be realized by detecting the DIR bit of the first register 70.

Processing 111 extracts the image data determined by the data determination processing manual mode and the data determination processing automatic mode as data for information processing, and also extracts the image data determined by the data determination processing manual mode and the data determination processing automatic mode as data for information processing.
) is displayed on the screen.

As described in detail above, according to this embodiment, the amount of movement of the image reading device per unit time is monitored, and the boundary line of the image data is read at a point where the amount of movement is smaller than a predetermined standard. By doing so, the operator can easily designate the cutting position while checking the displayed image data to cut out any part of the image data, thereby improving the operability.

Furthermore, according to this embodiment, the process of determining the read image data can be automatically executed using a predetermined algorithm as necessary, improving the operability of the operator when cutting out the necessary part of the image. The effects that lead to this are significant.

Furthermore, by automatically detecting the moving direction of the image reading device 10, it is possible to match the read image and the displayed image even when reading operations are performed in any direction (forward or reverse direction).

Another effect of this embodiment is that the finalization process for image data divided into blocks by boundary lines is performed interactively while checking the displayed image in manual mode, thereby combining two images located at separate positions. You can also make edits such as changing the opponent's position.

[Effects of the Invention] As described above, according to the present invention, image data is automatically classified by moving and stopping the image reading device during a reading operation, so the operator only needs to input an instruction to select the classification. Image data obtained by photoelectrically converting a desired image area can be obtained with a simple operation.
