Abstract

PURPOSE:To contrive to miniaturize a coordinate detector by inputting a coordinate from a digitizer in designating a coodinate input and using a coordinate input area for the operating section to apply mode designation in designating the mode input. CONSTITUTION:In inputting a coordinate, an original is placed upward to a corner indicated by the arrow 5 printed on a coordinate detection region 3. In depressing a desired part of the original by a stylus pen 2, the X, Y coordinate from the home position of the original is inputted to a copying device (not shown). Moreover, in designating the mode input by an input mode changeover switch 4, when one of each mode is depressed by using the stylus pen 2, the mode designation is inputted to the microprocessor unit of the copying device main body. Thus, a coordinate position detection element 7 has only to have nearly the same size as the coordinate position detection region A and no other operation area is required, then the digitizer is minimized.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an image area specifying device, and more specifically, for example, an image area specifying device for specifying an image area of a document to be copied and forming only an image of that area on transfer paper. The present invention relates to an image area specifying device, that is, a digitizer, for use in a copying machine capable of printing.

<Prior Art> In recent years, copying apparatuses that are equipped with various new functions and are designed to be multifunctional have come into use.

One of the new features is a multiple copy function. In this method, multiple originals are copied onto one side of a single sheet of transfer paper. For example, assume that there are two originals, one of which has an image in a corresponding part, and the other original with an image in a different part. First, if you copy one image onto transfer paper and then copy the other image onto the same side of the transfer paper, you will get 2
Multiple copies are completed by copying the original images on the same side of one sheet of transfer paper. Such copying could also be performed with conventional copying machines. That is, the transfer paper that has been ejected from the device after the first copy has been completed is made to correspond to the second copy,
It may be fed into the copying machine again using a manual feed mechanism or the like. In contrast, in recent copying machines, when multiple copying is selected on the operation panel, transfer paper is automatically circulated within the copying machine, and multiple copies can be performed by replacing multiple originals. Additionally, by arranging multiple originals (for example, two originals) on the original table of the copying machine, multiple copying can be automatically performed by selecting multiple copying without having to replace the originals. ing.

Another new feature is the multicolor copying function.

This uses a color (for example, red, blue, etc.) developer instead of the usual black developer, thereby making it possible to obtain a colored copy image. One method is to replace the black developer in the copying machine with a color developer, but
In recent copying apparatuses, a plurality of color developing units in addition to a black developing unit are stored in the apparatus in advance, and color images can be automatically obtained by selecting color copying on the operation panel.

By combining the multiple copying function and the multicolor copying function described above, it is possible to further increase the functionality. in this case,
If you select multiple copying or color copying, you can automatically obtain colored images of multiple originals on the same side of one sheet of transfer paper. Further, depending on the selection method, it is possible to obtain a multiplexed or multicolor image by making the image of one original document black and the image of another original document colored.

In addition, one new function is the area specification function (or
There is also a coordinate position detection function). This is a method of extracting and copying only the image of a necessary area from one original image. The conventional method is to first mark a desired image area with an X.

When the Y-coordinate dimension is measured and the value is input on the operation panel, the light emitting element array installed near the photoconductor that forms the image emits light partially and in chronological order in response to the signal, and the photoconductor This method erases electrostatic latent images in unnecessary areas on the body, thereby obtaining images of the necessary areas.

Recently, areas have been specified using coordinate position detection elements (so-called digitizers). This has a position detection element (such as a sheet resistor) built into a board that is the same size as the original, and when pressed from the outside it detects the position (X).

Y coordinate) can be detected. Using this,
If you place the document on the digitizer and press the desired image area, that area will be automatically detected, eliminating the need to measure and input the required area as described above, and it can be done visually and easily. This is very convenient, and the area specification function can now be used effectively.

However, the conventional digitizers described above require a coordinate position detection element surface that is small (or smaller) than the document size that can be copied by the copying device used, and in addition to the above, it is necessary to read input coordinates and specify Modes such as whether or not to display the area in the image, or when using a copying machine with multiple color developing devices, what color to paint the specified part or what color to paint the outside of the designated area. An operating section was required for input.As copying machines become more multi-functional, the number of these modes increases as the number of other colors and the number of specified areas increases. There is.

For this reason, the operation parts of coordinate position detection devices are gradually becoming larger.Therefore, in conventional coordinate position detection devices, the surface of the coordinate position detection element is at least the same size as the document size that can be copied. Since the area of the operation section for inputting and the like is the same size as both, the size of the coordinate position detecting device is increased.

FIG. 2 is a schematic diagram of a conventional coordinate position detection device. The area shown in the figure is the coordinate position detection area, and an operation unit with mode keys is provided on the front side thereof. Therefore, the coordinate position detection device is shown to be larger by the dimension indicated by X in the figure.

Problems to be Solved by the Present Invention> As mentioned above, in the conventional coordinate position detection device, it is necessary to have an area for the operation section in addition to the coordinate position detection surface, which leads to an increase in the size of the entire device. Ta. Furthermore, as coordinate position detection devices and copying devices that work with them become more multi-functional, the operation parts of the coordinate position detection devices may become more complex and larger, leading to further increases in the size of the coordinate position detection devices. There was a risk.

<Object of the Invention> The present invention solves the drawbacks of the conventional coordinate position detection device (hereinafter referred to as a digitizer) as described above, and provides a compact, space-saving, and reliable device that does not require an area for an operation section. The purpose is to provide a highly efficient and inexpensive digitizer.

In order to achieve the above purpose, the digitizer has only one switch outside the coordinate input canister for switching between coordinate input and mode input, so that when coordinate input is specified, is characterized in that when coordinates are input from a digitizer and a mode input is specified, the coordinate input canister can serve as an operation unit for specifying the mode, etc.

<Example> The present invention will be explained below based on the illustrated embodiments.

FIG. 1 shows an embodiment of a coordinate position detection device to which the present invention is applied. 1 is a digitizer according to the present invention, and a plane indicated by 3 is a coordinate position detection area. When inputting coordinates using the present invention, a document is placed facing upward at a corner indicated by an arrow 5 printed on the coordinate position detection area 3. Next, if you press the desired part on the document with the stylus pen 2,
The X-Y coordinates from the reference position of the original are input to a copying machine (not shown).

4 in the figure is a seesaw switch, which is an input mode changeover switch for switching between coordinate input and mode input. Further, the part indicated by 6 is an operation pattern printed on the coordinate position detection area, and when one part of each mode is pressed with the stylus pen 2 when mode input is specified with the input mode changeover switch 4, A microprocessor unit (not shown) in the main body of the copying apparatus is configured so that the mode designation is inputted in advance.

Third. FIG. 4 is a longitudinal sectional view of a conventional digitizer. What is shown in FIG. 3 is a digitizer that uses a part of the coordinate position detection element 7 to specify the mode, and in addition to the coordinate position detection area A, it also detects the coordinate position in area C for mode input. The presence of element 7 led to an increase in the size of the digitizer. FIG. 4 is a cross-sectional view of a digitizer in which mode input is performed using another detection switch 8. As shown in FIG.

In this case, the coordinate position detection element 7 has a size corresponding to the coordinate position detection area A, but in addition to this, the size of the area of the mode switches 8 arranged in the longitudinal direction corresponding to the types of modes and the substrate holding them etc. There was a need for sanity. In addition, in the case of this method, not only the size of the device but also the mode switch 8 is required for each type of mode, which leads to a decrease in the reliability of the device and an increase in cost.

FIG. 5 is a longitudinal sectional view of this embodiment. According to this configuration, the coordinate position detection element 7 has approximately the same size as the coordinate position detection area A, and no other area for an operation section is required, so that the digitizer can be made smaller. In addition, in Fig. 1, an example is shown in which the input mode changeover switch 4 is provided on the digitizer body, but this switch is attached to the stylus pen 2.
It can also be installed on the handle. Needless to say, the digitizer itself can be further downsized.

FIG. 6 is an example of input program processing according to FIG.
It is included in the memory ROM in the processor CPU shown in the figure. The switch 4 is connected to one of the CPU's input terminals, and the sensitive surface input of the digitizer-1 by the stylus pen is dynamically connected to the other inputs. The signal for this dynamic scanning is a group of time difference pulses D periodically outputted from the CPU, and the points input by forming a matrix K with this pulse correspond to each dot position on the sensitive surface of the board.

For example, assume a 6×16 matrix. In the flowchart of FIG. 6, after turning on the power of the digitizer, switch 4
When you insert the LED (L +
~L3) lights up to enable coordinate input, and when the stylus pen is touched on the board surface, the CPU reads the position coordinates corresponding to the dot at the touch position via matrix K,
The X and Y coordinate data is transferred from the data bus to the RA in the CPU.
Store in M. Next, when switch 4 is turned off, the previous LED
turns off and mode input is enabled, and if you touch pattern 6 of mode input on the same sensitive surface as coordinate input with the stylus pen, no matter where you touch within that mode pattern, for example, the same data of mode 1 will be stored in the RAM in the CPU. However, even if you touch it again, it will not be input unless you give a clear command (touch C to clear).

Thereafter, the CPU outputs data for image editing (trimming, masking, movement, etc.) based on the mode data from the data bus DB.

Effect> As described above, according to the present invention, the size of the main body of the coordinate position detection device can be made almost the same size as the coordinate position detection area, and the size of the device can be reduced and the associated cost savings can be reduced. pricing,
Lighter weight can be achieved. In addition, it has the effect of improving the reliability of the entire device and further reducing the cost of the device because it does not require any sensing elements other than the coordinate position sensing element and the input mode changeover switch, which are related to the type of mode. be.
