8 is an original feed port for sending the original into the main body 2, and the original 4 is placed on the original platen 3 and is subjected to an operation such as copying, or the original 1144 is transferred by driving a feeder (not shown). The data can be fed into the host device body 2 from the feeding lower, and after being subjected to processing such as copying inside, can be discharged from the feeding port 8.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional image processing apparatus, when an attempt is made to specify coordinates for a thick bound document made of wood or the like, the digitizer 1 to the indicator pen 6 Since the distance between the two points is too great, input is impossible, and coordinate values with large errors can only be obtained.

In addition, since editing and other processes are performed based on the reference position 5 on the document table 3, when the document 4 is placed on the document table 3 or during work after being placed, it may deviate from the reference position 5. In addition, when specifying a plurality of areas, it is difficult to confirm the specified range, which is another problem.

The purpose of the present invention is to focus on the above-mentioned conventional problems, and to solve the problems, it is possible to accurately manually perform specified position coordinates or areas even on thick originals such as those made of wood.
Another object of the present invention is to provide an image processing device that can confirm a specified area.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a coordinate indicating means for indicating positional coordinates on a document image, and a region or position coordinates indicated by the indicating means can be input. An image processing apparatus that performs predetermined processing on area or position coordinates manually entered by the coordinate input means, the image processing apparatus comprising a transparent coordinate input means superimposed on the upper surface of the original image. The present invention is characterized in that it is possible to specify the area or position coordinates on the document image using the coordinate specifying means through the transparent coordinate input means.

C Effect] According to the present invention, since the transparent coordinate input board is kept close to the top surface of the document while maintaining parallelism with the surface of the document,
By simply specifying the coordinates or area on the document via the coordinate input board by the coordinate specifying means, the coordinates or area can be accurately input.

Further, even in the case where a plurality of areas are specified by using a transmissive display on the document table, erroneous operations such as double specification can be prevented by clearly indicating these areas.

[Examples] Examples of the present invention will be described below in detail and specifically based on the drawings.

FIG. 1 shows one embodiment of the present invention, where 11 is a coordinate input board (digitizer), and the digitizer 11 may be of any type, such as a resistive film type or an electrostatic coupling type, but it is transparent. A flexible material such as glass is used as the substrate, and in the case of this example, the client
．． 1-12371Q) is used. That is, the elastic wave digitizer is designed to detect the coordinates of a position indicated by the pointing pen 6 from the delay in the arrival time of the elastic wave, and a transparent material such as glass is used as the propagation body of the digitizer.

The transparent digitizer 1 is placed so as to overlap the original 4 placed on the original platen 8 from above, and the area can be specified while visually viewing the original 4 below through the overlapping transparent digitizer 11. Editing operations such as editing, correction, and addition can be performed using the pointing pen 6. Furthermore, in this example, a pair of FIGS. 3A and 3B are provided at one edge of the transparent digitizer 11 so that the document 4 may be in the form of a thick book as shown in FIG. A hinge member 12 as shown in the figure is attached, and this hinge member 1
2 supports the digitizer 11 itself vertically and allows the digitizer 11 to rotate around its pin 12A. 12B is a spring that supports the vertical hinge 12C of the hinge member 12 so as to be able to move up and down.

Thus, regardless of the thickness of the document 4, the transparent digitizer 11 is kept parallel to the document table 3, ie, flat, via the hinge member 12, and the document 4 is placed in the reference position or in the horizontal direction.
There is no misalignment between the digitizer and the digitizer 11.

FIG. 4 shows a second embodiment of the invention. In the first embodiment described above, it is necessary to set the original fA 4 at the reference position of the transparent digitizer 11, but in this second embodiment, the transparent digitizer 11 is set in the two horizontal directions of the X-axis and the y-axis. It should be movable. That is, 21 is a guide rail in the X-axis direction, 22 is a guide rail in the y-axis direction, 23 is a movable support member that supports the transparent digitizer 11 so as to be movable along the guide rail 22, and 24 is a movable support member that supports the guide rail 22 in the guide rail 21. 25 is a guide fixing member fixing both ends of the guide rail 21.

On the other hand, the transparent digitizer 11 is provided with a cursor line 13 that indicates a reference position 5 when inputting coordinates. Therefore,
For example, when specifying an editing area from the manuscript, first place the manuscript 4 at an arbitrary position on the manuscript table 3 with only the X-axis direction and the y-axis direction aligned in the same manner as in the first embodiment. Next, the transparent digitizer 11 is moved 8 times in the X@force direction and the yLith direction with respect to the document 4 by the above-mentioned moving means. Then, the coordinates may be input while the cursor line 13 indicating the reference position 5 and one corner of the document 4 are aligned.

Note that 14 is a signal line.

FIG. 5 shows a third embodiment of the invention. In this example, in addition to the eight movements of the transparent digitizer 11 in the X-axis direction and the y-axis direction, the digitizer 11 can be rotated on a horizontal plane. X @ and y for each edge! There is no need to match i[h. Here, reference numeral 26 is a socket type connecting member provided on the movable support member 23, supporting the digitizer 11 so as to be swingable in the I-plane direction, and allowing the digitizer 11 to be freely attached and detached.

FIG. 6 shows a fourth embodiment of the invention. In this example, a rotary encoder 30 is incorporated into each of the movable support members 23 and 24 of the apparatus shown in FIG. 4 or 5. Although FIG. 6 shows a state in which the encoder 30 is incorporated into the movable support member 24 in the X-axis direction, the movable support member 23 in the Y-axis direction also has a similar configuration. In this way, by incorporating the encoder 30, it is possible to detect the amount of movement of the moving member 24 in the X-axis direction and the amount of movement of the moving member 23 in the y-axis direction. The coordinates of the intersection point of the cursor line 13 in the y-axis direction can be calculated, and by using this reference point coordinate value as an offset value for each coordinate, the coordinate values detected by the digitizer 11 can be converted into actual coordinate values. . Note that such calculations may be performed by a microprocessor attached to the digitizer, or may be performed by a processor on the device main body 2 side.

FIG. 7 shows a procedure for calculating input coordinate values according to the fourth embodiment described above. First, after initialization is performed in step S1, offset values X of the reference point in the X-axis direction and the y-axis direction are determined in step S2. f and y. f is detected via the encoder 30, and in the next step S3, the indicated coordinate values xd and yd on the digitizer 11 are read, and the process further advances to step S4 to detect the above-mentioned X.

The actual coordinate value X from f and Xd, and y. f and y.

The actual coordinate value y is calculated from the coordinate value y, and these coordinate values X and y are output to the host device 2 side in step S5.

FIG. 8 shows a fifth embodiment of the invention. In this example, a transparent digitizer 11 is integrated with a transmissive display. Therefore, the document is viewed through the transmissive display 40 integrated with the transparent digitizer 11, and if the range A-A' is specified on the digitizer 11 using the specifying pen 6, the display 40 An area 41 (indicated by diagonal lines) corresponding to the range is displayed. Note that 42 is the display 40 due to the previous specification of the range A-A'.
Indicates the area displayed above.

Even if you specify multiple areas one after another in this way, all of the information is displayed as is on the display 40, which prevents erroneous operations such as double specification, and allows you to check the information on the manuscript that is involved in editing work. Since everything can be displayed in an orderly manner on the display 40, it is possible to provide an image processing device that is easy for the operator to use. Further, if the host device 2 is capable of digital processing such as an LBP, it is also possible to display additional information such as characters and figures in a specified range. Furthermore, messages, menus, etc. from the host device 2 are displayed on the display 40,
It is also possible to perform the operation using the pointing pen 6. The above-mentioned transmissive display 40 may be of any type as long as it is a translucent display such as a translucent liquid crystal display.

In the embodiments described above, the host device is a copying machine, but the present invention is not limited to copying machines, but is applicable to various types of image processing such as facsimiles and image data processing devices. Needless to say, it can be applied to devices.

[Effects of the Invention] As described above, according to the present invention, a transparent coordinate input device is superimposed on the top surface of a document, and a coordinate indicating means such as an indicator pen is used to input information on the document via a coordinate manual device. Since it is now possible to specify coordinates or areas, it is possible to specify coordinates accurately regardless of the thickness of the document, even if the document is made of thick material such as wood. It has become possible.
