PURPOSE:To set and change coordinates simply by providing a memory device, the first memory controlling device, a coordinate input controlling device, a discriminating device and the second memory controlling device. CONSTITUTION:At a point of time when inputting of necessary number of coordinates is completed, a point of the highest ranking out of points stored in a memory device 63 as coordinate input state is set to the state of coordinate not inputted state by the first memory controlling device 66, and the point is made to the state of coordinate input possible. When new coordinate inputting is made, it is accepted as coordinate of a point of highest ranking out of points set to the state of coordinate not inputted. Accepted point is made to coordinate input state judging that a point of next ranking is in coordinate input state by a judging device 65.

Thus, operation for changing coordinate value and setting of areas can be simplified.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an area setting device, and more specifically,
The present invention relates to an area setting device that can set a desired area by setting the coordinates of two points in a diagonal direction.

<Prior Art> There has been a strong demand for multifunctionality in image forming devices such as copying machines, and in order to satisfy this demand, image formation is performed only within a set range for the image signal obtained. Some devices have been provided that have editing functions such as operations for performing image forming operations (hereinafter referred to as trimming) and operations for not performing image forming operations only within a set range (hereinafter referred to as masking).

In such an image forming apparatus, it is essential to set an area for editing processing, and an area setting device for setting the area is installed.

Then, in the area setting device, a document is set under a cover having a grid pattern and an indicator indicating coordinate values in mutually orthogonal directions, and a mode such as trimming, masking, etc. is selected by performing a key operation. Then, while operating the coordinate designation key and the X key, use the numeric keypad to enter a numerical value corresponding to the setting range related to the Accordingly, a configuration is adopted in which a desired area can be set by inputting a numerical value corresponding to the setting range related to the Y-axis (see Japanese Patent Laid-Open No. 58-43480). Also, if you want to change the coordinates of a point that has already been set and input, first operate the coordinate conversion key, then input the new coordinates by operating the X key, Y key, or numeric keypad. The configuration allows settings to be input (see the above publication).

<Problems to be Solved by the Invention> With the area setting device having the above configuration, it is possible to set a desired area or change an area once set by sequentially performing the necessary key operations. Yes, but
There is a problem in that the key operations are complicated, making it extremely difficult for an inexperienced operator to perform the operations, and increasing the risk of setting or changing coordinates by mistake. In particular, when changing the coordinates, there is a problem in that coordinates that do not need to be changed are changed, resulting in a completely unexpected image being formed.

This invention was made in view of the above problems,
It is an object of the present invention to provide a region setting device that allows coordinates to be easily set and changed by the same key operation.

<Means for Solving the Problems> To achieve the above object, the area setting device of the present invention includes a storage means, a first storage control means, a coordinate input control means, a determination means, and a second storage control means. and storage control means.

The storage means selectively stores a coordinate input state and a coordinate non-input state in correspondence with each point that can be input, and the first storage control means stores the coordinate input state at the end of coordinate input. The first point among all the points in the area where is stored is
The points in the ranking are stored as coordinates not input, and the coordinate input control means accepts only the key input for the highest ranking point among the points stored as coordinates not input. The means determines that a point next to the point stored as a coordinate-uninput state is stored as a coordinate input state, and the second storage control means receives a determination signal from the determination means. □ When the coordinates of a point that is stored as an input state is input, or when it is confirmed that no new coordinates will be input for the point, the point is stored as a coordinate input state. At the same time, the next ranked point is stored as a state in which coordinates have not been input.

Function> If the area setting device has the above configuration, if the coordinates of a point are set by key operation, the coordinate input control means will allow the coordinate input control means to input the coordinates of the point stored in the storage means in a state where the coordinates have not been input. The coordinates of all the necessary points can be set by accepting the coordinates of the point with the highest rank among them, storing the point in the storage means as a coordinate input state, and repeating the above operation one after another.

Then, when you have finished inputting the required number of coordinates, the first
The storage control means sets the highest ranked point among the points stored as coordinate input states in the storage means into a coordinate non-input state, thereby making the point into a coordinate input enabled state.

After that, if you enter new coordinates, they will be accepted as the coordinates of the point with the highest rank among the points set in the coordinate-uninput state, and the next-ranked point will be in the coordinate input state. By determining that there is, the accepted point is placed in a coordinate input state, and the next ranked point is placed in a coordinate uninputted state, and the next ranked point is placed in a state where new coordinates can be accepted. . Also, instead of inputting new coordinates, even when it is confirmed that no new coordinates will be input, the point will be set to the coordinate input state, and
It is possible to set the coordinates of the next ranked point to a state where no coordinates have been input.

<Example> Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.

The signal from the numeric keypad (55) and the signal from the coordinate input key (57) are applied to the storage unit (61) that stores the coordinates of each point through the coordinate input control unit (62), and then the coordinate input control unit (62) is applied to the storage unit (61) that stores the coordinates of each point. A signal from the input key (57) is applied to a storage section (63) that stores the state of each point divided into a coordinate input state and a coordinate non-input state. In addition, the storage section (63)
The information indicating the status of each point from the coordinate data is applied to the determination unit (65) under the control of the readout control unit (64) to which the signal from the coordinate data call key (51) is applied. The signal from the oyster (57) is
), the discrimination signal from the discrimination section (65) is applied to the first storage control section (66), and the discrimination signal from the discrimination section (65) and the signal from the coordinate implantation key (57) are applied. The voltage is applied to the second storage control unit (67), the first storage control unit (66),

is applied to.

With the configuration shown in F below, at the beginning of the area setting operation, first operate the editing operation state selection key (50) and then operate the editing mode selection key (54) to select a mode such as trimming or masking. In the selected state,
Operate the numeric keypad (55) so that the value displayed on the coordinate value display (53) becomes the desired value, then press the coordinate entry key (
57), you can set the coordinate value of one of the points in the first order (in this case, for example, X direction input x 1-1 will be displayed), and then press the numeric keypad (57) again.
5) and the coordinate input key (57), it is possible to set the other coordinate value of the above point. In this case, for example, Y direction input Y1-1 is displayed. ). At this point, a signal from the coordinate input key (57) changes the part corresponding to the point in the storage section (63) to indicate the coordinate input state.

Thereafter, by repeating the above operations, the coordinates of the points in the diagonal direction of all the areas to be set can be set. Then, when the coordinates of all points are set, the storage section (
63) is changed so that it does not indicate the state of coordinates entering the floor.

Furthermore, even after setting the coordinates of all the necessary points as described above, if you wish to change the set values, you can first operate the coordinate data call key (51), and then Among the points whose coordinates have not been input in (63), the coordinate values of the point with the highest level are read out from the storage unit (61) and displayed on the coordinate value display (53), and the coordinates of one of the points are The corresponding coordinate input status indicator (
52) is turned on.

Therefore, in this state, by operating the numeric keypad (55) and the coordinate input key (57), new coordinate values can be input in place of the original coordinate values in the storage section (
61).

Further, for points whose coordinate values do not need to be changed, it is sufficient to operate the coordinate input key (57) again, and the next ranked point is displayed as a changeable point.

FIG. 3 is a diagram showing an embodiment of the storage section (63).
It is composed of a bit memory, and the coordinate input state is distinguished as 1111, and the coordinate non-input state is O''.Then, from the lowest to the lowest, the X coordinate, Y coordinate of the first point in the first area, etc. - The coordinates are made to correspond to the X and Y coordinates of the second point in the second area, and only the point corresponding to the bit indicating the lowest "0" state is allowed to input coordinates.

Therefore, to display a point whose coordinates can be input, the coordinate input status indicator (52) indicating the point corresponding to the lowest bit of the bits indicating "O" in the storage section (63) blinks. At the same time, the coordinate input status indicator (52) indicating the point corresponding to the bit indicating the 1111+ status is lit continuously, and the coordinate value indicator (53) is caused to blink to display the coordinate value of the point. This is done by

In addition, when inputting coordinates, it is determined whether the bit next to the bit indicating the lowest "0" state is in the "0" state, and if it is in the 110 II state, the coordinate input operation is executed. 111 I
If it is in the + state, it is changed to the "0" state after the coordinate input operation is performed. In this case, the input coordinate values are written in the storage section (61) regardless of the above state.

A to E in the same figure show the storage unit (63
), and each time a setting input is performed, the bit states are changed to "1" and "1" in order from the lowest bit.

Furthermore, if you wish to change the coordinate values after inputting the coordinate values for the required point, by operating the coordinate data call key (51), as shown in FIG. II OI+
Since the state is changed, new coordinate values can be set by performing necessary key operations. Then, in the state where the new coordinate values have been set, as shown in G in the same figure, the lowest bit is changed to the "1" state, and the next bit is changed to "゛O゛'O゛'. The state can be a state in which the coordinate value corresponding to this bit can be input.

<Effects of the Invention> As described above, the present invention allows setting coordinate values to be sequentially set without any special operations by storing each settable point in a coordinate input state or a coordinate non-input state. Furthermore, once the set coordinate values are recalled, the coordinate values can be easily changed by simply inputting the new set values, simplifying the operation for setting the area. It has the unique effect of being able to
