Abstract

PURPOSE:To change the thickness of a display line corresponding to the pen pressure of a input pen tip by providing a mechanism detecting the movement of pin chip in 3 stages. CONSTITUTION:In applying coordinate input while the pin tip 6 of an input pen 5 is depressed onto an digitizer 7, the pen tip 6 is moved in the inside of the pen in response to the pressing force. Since switches 1, 2 are provided in the pen along a moving direction, the switch 1 is turned on with pen-up, when the pen is depressed strongly, the switch 2 is turned on and when the pen is deprssed weakely, both the switches 1, 2 are turned off. Thus, when both the switches 1, 2 are turned off, a fine line is drawn and when the switch 2 is turned on, a thick line is drawn by activating a data processing circuit 9 and the result is outputted to a picture memory 10.

Description

[Detailed Description of the Invention] [Summary] A data input pen and input device for inputting data when reading and displaying, for example, handwritten characters, figures, etc. By changing the thickness of display lines using an input device, it is possible to display images that are close to natural.

[Industrial application field]

The present invention relates to an input pen and an input device, and it is possible to reduce the error between an input image and an output image when controlling line display when performing handwriting input, and to display a more natural image. It was requested.

[Conventional technology]

The configurations of conventional input pens and input devices are shown in FIGS. 6 and 7.

In the figure, 1.2 is a switch, 3 is a contact, 4 is a spring, and 5 is a main body.

Conventionally, in the configuration shown in FIG. 6, pen pressure is applied during input, and when the contact point 3 is released from the switch 1, pen down is detected and a line is displayed on the display device.

On the other hand, in the configuration shown in FIG. 7, when the contact point 3 contacts the switch 2 due to the pen pressure during input, pen down is detected and a line is displayed on the display device.

[Problem that the invention seeks to solve]

When using a pen with such a configuration, as shown in Figure 6, the pen is considered to be in a down state until the writing pressure becomes low and the contact point 3 contacts the switch 2. When "cutting out" lines, the lines are displayed longer than necessary, as shown in FIG. 8(A). For the type shown in Figure 7, the moment the pen pressure becomes low, the contact point 3
is removed from switch 2, so it is considered that the state has shifted to the pen amplifier state. Further, the period from when pen pressure is applied until the contact point 3 contacts the switch 2 is considered to be a pen-up state. Therefore, the beginning and end of the input line are
), there was a defect that it was displayed as being missing.

Further, in the configurations shown in FIGS. 6 and 7, since the pen pressure cannot be detected, it is not possible to process thin lines, thick lines, etc. according to the pen pressure.

[Means for solving problems]

As shown in FIG. 1, the present invention provides switches 1.
2 is provided to detect the writing pressure of the pen tip 6 in three stages as shown in FIG.

This process performs thin line display processing.

[Effect]

As shown in the flowchart in Figure 3 (writing pressure is applied to the pen tip 6, the contact 3 releases the switch 1, and the switches 1 and 2 become as shown in Figure 2! 32), the data processing unit 9 issues a thin line display command and the thin line is When the display is performed and the contact point 3 comes into contact with the switch 2 to enter state 3 in FIG. 2, a bold line display command is issued from the data processing section 9 to display the thick line.

As described above, in the present invention, by detecting the pen pressure with the input pen 5 and controlling it with the data processing section of the handwriting input device, an image faithful to the input image can be displayed as shown in FIG. 4.

〔Example〕

Embodiments of the present invention will be described in detail using screens.

FIG. 5 is a diagram showing an embodiment of the present invention, and in FIG.
1 and 2 are switches, 3 is a contact, 4 is a spring, 5 is an input pen, 6 is a pen tip, 7 is a digitizer, 8 is a digitizer control circuit, 9 is a data processing circuit, 10 is an image memory, 11
is a CRT.

12 indicates a printer, and 13 and 14 indicate signal lines, respectively.

In Fig. 5, two switches are installed along the moving direction of the contact point 3 inside the input pen 5, as shown in Fig. 2. It is configured to be able to output a standard signal, and further to be provided with a data processing circuit 9 that changes the thickness of the line depending on the signal.

With this configuration, when the input pen 5 starts inputting, pressure is applied to the pen tip 6 of the input pen 5 to press the paper surface, and the switch 1 is released from the contact point 3.
In the data processing circuit 8, a signal from the digitizer control circuit 8 that detects a point on the coordinates of the digitizer 7 is processed as a thin line, inputted to the image memory 10, and displayed on the CRTll.

When the input is continued and writing pressure is applied to the pen tip 6, the contact point 3 and the switch 2 come into contact, and the data processing circuit 9 sends the signal from the digitizer control circuit 8 to the thick line processed image memory 10 and displays it on the CRT II.

The contents displayed on the CRT in this way can also be printed out from the printer.

〔Effect of the invention〕

When the input pen 5 is configured as shown in FIG. 1, when pressure is applied to the pen tip 6, the contact 3 releases the switch 1, so that the display starts immediately, and when the switch 2 and the contact 3 are in contact, If there is no pen pressure when writing, the contact 3 will be released from the switch 2, but because of the presence of the switch 1, the line being input will not be interrupted and will be displayed. Also switch 1, 2
Since the data from the digitizer can be divided into thick lines and thin lines by the signal output from the digitizer, a display similar to the input image as shown in FIG. 4 can be performed.
