Abstract

PURPOSE:To provide a pen input processor which is capable of absorbing the jiggle of a pen which occurs when a graphic and frame information are designated. CONSTITUTION:In a pen input processor where a graphic and frame information are designated by the input to the input tablet of a pen and an instruction to move the graphic and frame information, etc., is imparted by pulling up a pen point designated from the input tablet, the jiggle of a pen which occurs when the graphic and frame information are designated is absorbed because instructions to neglect a moving distance and to move the graphic and frame information, etc., are imparted (step S8) when the moving distance is within a fixed range by deciding the size of the moving distance (step 37) when the pen moves from the falling position of the pen to the pulling up position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pen input processing device, and more particularly to a processing device using a pen as an input means, and more particularly to a word processor and a graphic data creating device.

[0002]

2. Description of the Related Art Conventionally, in this type of processing apparatus, when a figure or a frame is designated by a pen by the conventional designation method, the pen is shaken at the same time as the pen down for designating the figure or the frame, and a drag ( Move operation) is entered, and figures and frames move slightly.

This is because it is not considered that it is very difficult to simultaneously make a pen-down point and a pen-up point in a point designation operation with a pen.

For example, assume a case where a shaded circle of a graphic is desired to be changed to a dotted line (FIG. 3-1). In this case, it is common to first specify a circle with a pen (Fig. 3-2) and then change the type of shading (Fig. 3-3) by specifying a function or icon (Fig. 3-2). 4). However, in the conventional operating environment, when the circle was specified with the pen, the pen often moved and the circle moved from its original position (FIGS. 3-5 to 3-6).

[0005]

As described above, in the conventional processing apparatus, when a figure or a frame is designated by the pen, a drag occurs due to the movement of the pen simultaneously with the designation, and the figure or the frame is moved. There was a problem.

The present invention has been made in consideration of such circumstances, and according to the present invention, the blurring of the pen generated when designating a figure or a frame is absorbed, and the figure moves when only the figure is desired to be designated. It is an object of the present invention to provide a pen input processing device that prevents the user from doing so and can easily perform a graphic designation operation.

[0007]

According to the first aspect of the present invention, a figure or frame information is designated by inputting with a pen input tablet, and the designated pen tip is pulled up from the input tablet to draw the figure or frame information. In a pen input processing device that gives an instruction to move frame information, etc., when the pen moves from a position where the pen is dropped to a position where the pen is pulled up, a determination unit that determines the magnitude of the movement distance and the movement distance are The pen input processing device is composed of processing means for giving an instruction to move the figure or frame information while ignoring the movement distance when it is within a certain range.

[0008]

According to the present invention, a pen for designating a figure or frame information by inputting to the input tablet with the pen and giving an instruction to move the figure or frame information by pulling up the designated pen tip from the input tablet. In the input processing device,
When the pen moves from the dropping position of the pen to the pulling position, by judging the size of the moving distance,
If the movement distance is within a certain range, the movement distance is ignored, and an instruction to move the figure or frame information is given, so that the blurring of the pen that occurs when designating the figure or frame information is avoided. It can be absorbed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. The present invention is not limited to this.

FIG. 1 is a block diagram showing a device configuration of an embodiment of the present invention. 1 is a central processing unit (CPU) that executes programs, and 2 is an RA that stores various data
M, 3 is a ROM for storing a control program, 4 is a printer controller, 5 is a printer, 6 is an IC card, 7 is an IC card interface, 8 is a floppy disk (FD), 9 is an FD contra, 10 is a keyboard, 11
Is a key interface, 12 is a pen, 13 is a pen interface, 14 is a display device, and 15 is a display controller. The IC card 6 and the FD 8 are controlled by the IC card interface 7 and the FD controller 9, respectively, and data can be loaded / saved. The key interface 11 is the keyboard 1
The key pressed with 0 is discriminated and converted into the corresponding data. In addition, the pen interface 13 is a pen 12
The type of event (event) and the coordinates on the screen pressed by the pen are discriminated and converted into the type of event such as pen down / pen up / drag and the coordinate data on the screen.

When a figure or frame is designated by the pen, a pen down event (pressing of the pen) occurs from the pen interface 13 and is transmitted to the application program on the ROM 3 or the RAM 2 via the CPU 1. In the application program, if the event that occurred is a pen down, it is compared with the coordinate data of the graphic on the RAM 2 to determine which graphic is down, and the corresponding graphic data is displayed to the effect that it is currently being edited.
Further, when an event of dragging (the pen has moved) is input from the pen interface following pen down, the event is transmitted to the application program, and the application program determines whether to enable the dragging event according to the flow of FIG. If the movement range is small (for example, 3 dots or less), the drag event is ignored.

The operation of the pen input processing apparatus of the present invention will be described below with reference to FIG. The processing flow is step S1.
The pen interface 13 determines whether the pen 12 is moved up or down or the tip of the pen 12 is moved (dragped) on the display device 14 serving as an input tablet. If there is any, go to the next step.

In step S2, the pen interface 13 determines whether the drag is a drag. If the pen 12 is down now, since it is not a drag, the determination in step S2 is NO, and step S3 is selected. In the present invention, if it is determined in step S3 that there is a pen-down, the flag passes "1" in step S4 and the flag "1" to "enable drag neglect operation" is set in step S5. This flag stands in RAM2. At the same time, the pen-down coordinates are also detected, and R
It is stored in AM2. These processes are performed in step S5.

Next, at step S6, since the flag "1" has already been set and the flag "1" has been set all the time, it is judged that the drag operation should be ignored. As a result, in step S7, the number of dots moved by the pen dragging from the coordinates of the pen down in the RAM 2 is obtained. Then, in step S8, the RAM2
The number of moving dots is a predetermined number of dots (for example, 3 dots)
If it is smaller, the drag operation will be ignored.

However, tentatively, in step S8, the RAM
If the number of dots moved by the pen dragging from the coordinates pen-downed in 2 is larger than a predetermined number of dots (for example, 3 dots), ignoring the drag operation is invalid and the flag is " It becomes 0 ", and the operation to ignore the drag is not performed thereafter. Then, the movement process based on the instruction of the pen 12 in that case is performed.

If the pen 12 is now moved up in step S3, the determination in step S3 is NO, and step S11 is selected. In the present invention, if it is determined in step S3 that there is pen-up, the flag passes through step S11, and the "invalidate drag neglect operation" flag is set to "0" in step S12. This flag is cleared in RAM2. At the same time, the coordinates at the time of pen-up are also detected and stored in the RAM 2. Then, an instruction such as a movement process corresponding to pen down and pen up is given.

[0017]

According to the present invention, when a pen is used as an input means to designate a figure or frame by pen down and move them by dragging, the pen down is required when only the figure or frame is desired to be specified. The effect of facilitating the operation of designating a figure or frame can be achieved by ignoring the drag that always occurs due to the movement of the pen.
