FIG. 4 is a flowchart showing partial input operations and processing steps in one embodiment.

Here, the operation of one embodiment will be described with reference to FIGS. 1 to FA4. First, the normal input procedure of the image scanner will be explained with reference to FIGS. 1 and 2. The microcomputer 21 gives motor drive commands to the X-direction motor control section 23 and the Y-direction motor control section 24, drives and controls the stepper motors 3 and 6, and moves the image scanner head 2 to the reading start position.

Here, the pointer section P provided integrally with the image scanner head 2 is positioned above the 0 point shown in FIG. Then, a drive command is given to the X-direction motor control unit 23 to drive and control the X-direction stellar/4' motor 6, and the image scanner head 2 is controlled to move at a constant speed in the dog direction (rightward in FIG. 1). Start reading. Then, the image read by the image scanner head 2 is transferred to the image control unit 2.
5 and then stored in the image storage section of the memory 27. This image reading is continued up to KA in FIG. 1, which is the end position of one line, and when the reading of one line is completed, the
When the interface section P is located at point E, a drive command is given to the Y-direction motor control section 24 to drive the Y-direction Stellar 9 motor to move the image scanner head 2 to the corresponding point.
The image scanner head 2 is controlled to move in the Y direction (downward) by a distance corresponding to the reading width, and a drive command is given to the X direction motor control unit 23 to drive the (leftward) to move the image scanner head 2 to the image reading start position of the next line. Then, the image scanner head 2 is moved in one direction (to the left) by driving the X-direction robot again to start reading the image of the next line, and the input image is stored in the image storage section 25 of the memory 27. go. By repeating such image input scanning, the pointer P provided on the image scanner head 2 moves from the bottom row reading start position (point F in Figure 1) to the reading end position (point G in Figure 1). When the reading of the bottom row image is completed, the input of the image 1-2 is completed.

At this time, the movement of the image scanner head 2 is caused by rotationally driving the stem and arm motors 3 and 6, so that the amount of rotation is changed to the amount of linear movement in the Y direction and the X direction by the drive line 4.7, respectively. It is done based on the information that is converted and given.

Next, with reference to FIGS. 1 to 4, processing operations for partial input, which is the object of the present invention, will be explained.

Now, set the scanner input pan paper, point B in Figure 1,
Consider a case where you want to input a rectangular part surrounded by point C with a broken line. Assuming that the image scanner 2 is in the position shown in FIG. 1, the operator presses SW -X4-)13. At this time, the processing steps in FIG. 4 are (-830-
831-833846-853-S j O-) Loops while the above SW -X@11 is pressed. That is, at this time, the image scanner head 2 moves to the left. The oiler presses 5W-YH15 at the same time in order to move the pointer P provided on the image scanner head 2 closer to point B in Figure 1. -8
44) is added, and the image scanner head 2 moves in the -Y direction as well as in the -X direction. Then, the fourth controller turns on and off Junji XH3, 5W-YH5 so that pointer P is placed on point B.

At this time, when Do 2 exceeds point B to the image scanner, all you have to do is turn on and off SW -12, SW -Y (4414) and bring it to point B. This operation is easy for the operator. When the pointer P reaches point B, when SW-ADDBg716 is turned on, in the step of FIG. 4, (S29-S30-S

-850...]. At this time, the content of the C address of the partial input management table P-TBL is initially "'l", and is set to 0" in processing step S50.
After inputting the starting address of point B, set address C to “O”.
Let's erase the flag. As a result, in step S49, partial input management table P-position d, @
This means that the address of point B is stored as the first address. Next, again 5W-X @ 12° sw-y (branch) 14
is turned on and off, and the pointer portion P of the image scanner head 2 is placed on point C. Now, point D in Figure 1 is (X=O,
Y=O], and when the pointer P of the image scanner head 2 is located at point D, the contents of addresses a and b of the partial input management table P-TBL are '0#, and for each step, When proceeding in the X positive direction and Y positive direction, a and b respectively
The contents of the address are incremented by +1. When the pointer P reaches point C, addresses a and b contain the X and Y address values of point C. Here S)su' -ADDg 1cho1

When f-STA 77 is pressed, the process is C3so-8

53-854).

In step S54, image input processing is performed for a portion surrounded by points B and C in the wc1 diagram (area surrounded by a broken line). At this time, since the pointer P of the image scanner head 2 is at point C, the microcomputer 21 uses the partial input management table P-TBLfld, the contents of @ address and a,
The difference between the contents of address b is taken, and Rad2 is moved to the image scanner in the X and Y directions by the difference, and the pointer of Rad2 is first positioned at point B in the image scanner. Then, an image of the designated portion (area indicated by points B and C) is input. This partial input processing is first performed by S
Notifies that W-STA 11 has been pressed. Then, the scanner control section 20 moves the image scanner head 2 to the right side of the point B, which is a rectangular area surrounded by point B (contents of addresses d and a) and point C (contents of address f and 1g) in FIG. , and input image data. Next, move the image scanner head 2 in the Y direction to the reading width of the head, move it in the X direction to the contents of address a, move the image scanner head 2 again to the right to the contents of address f, and input the image. Let's do it. The input image data is sequentially stored in the image storage section of the memory 27,
Transferred to the higher-level device. The above-mentioned operation is repeated, and the image scanner head 2? Inter part P is g
When the content of the address is exceeded, the image input ends, and the image data below the content of address g (point C in the g1 diagram) is not transferred to the host device.

In this way, the partial input specified by the movement operation of the pointer section P is performed. In this way, a partial input range can be easily specified to the image scanner while moving the dot 2 and visually observing the image on the input paper, and the specified partial input can be executed.

By having the above-mentioned partial input processing function, when you want to partially input images such as two pictures of other materials when creating materials in the image scanner input that will increase in the future, you can use point B of the partial input range, Although the address of point C changes, partial input can be made quickly with a simple operation. Furthermore, since only images within the necessary range are input, unnecessary image data is eliminated, and data transfer time is shortened.

Here, a scanning method using a serial head is taken as an example, and partial input is possible in both the X and Y directions, but a scanner method using a line head, which has a reading width equivalent to the paper width, has a reading width in the X direction. In the case of a line head, partial input only in the Y direction is possible. Further, in the above embodiment, the image scanner itself has the control unit 20,
This example shows a configuration connected to a host device, but
When the microcomputer 21 shown in FIG. 2 is constituted by a computer main body CPU, the switches 11 to 16 are keys consisting of a key gate, and the computer main body CPU directly controls the image input control flS25 and the switch control unit 26.
, X direction and Y direction motor control@23, 24, etc., and may be configured to issue instructions to move the scanner head in the X and Y directions from the key gate.

In addition, the switches 11 to 16 and the switch control unit 26 are not provided, and the head movement in the x and Control instruction command @2
It may also be configured such that the operator directly issues a partial input instruction while looking at the paper. Also, Ste.

By providing the motors 3 and 6 with movement sensors, the amount of movement in the X and Y directions can be determined.
2 to 15 become unnecessary. Even in this case, the operator looks at the paper and moves r directly to the input area of the image scanner.

Furthermore, in the above embodiment, a pointer P is provided on the image scanner head 2, and a partial input range is specified by moving the image scanner head 2. An independent pointer movement mechanism may be provided to specify a partial input range.
