Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pen-type pointing device used in combination with an information terminal device having a coordinate position detecting device such as a tablet and a color display device such as a color LCD.

[0002]

2. Description of the Related Art There is a coordinate position detecting device such as a touch panel or a tablet as a device for directly inputting the coordinate position of a figure to a computer, which is used in combination with an input pen which a user holds and operates. In particular, the tablet has high position detection accuracy, and since the input pen can be operated with a fingertip, it is suitable for detailed operations such as drawing. A color display device with a pen input function has also been proposed in which a tablet and a flat color display panel such as a color LCD are combined to input a color figure or the like as if drawing directly (Japanese Patent Laid-Open No. 4-177518). Hereinafter referred to as Document 1).

When drawing a color figure with an input pen, it is necessary to select in advance which color to use. As this selection method, as described in the section of the prior art of Document 1, a method of arranging a color selection switch corresponding to each color on the tablet side and operating the color selection switch corresponding to the color to be used with an input pen is used. is there. However, in this method, the drawing space on the tablet is reduced by the space for arranging the color selection switch. In addition, if a selection palette is opened only when selecting a color like a commercially available drawing program, it will be difficult for a beginner to understand the color selecting operation.

Therefore, in Document 1, an input pen having a color selection function is proposed in order to solve such a problem. Specifically, a color selection switch corresponding to each color is arranged on the input pen side, and when the user operates one of the color selection switches, the color data corresponding to that switch is transferred from the input pen to the tablet side through the signal line. I am trying to notify you.

On the other hand, as another technique in which the function can be selected on the input pen side, there is a pen-type pointing device described in Japanese Patent Application No. 3-97947 (hereinafter referred to as Document 2). In this device, a rotary type changeover switch, a display unit, and a selection switch are mounted on the pen side, and one of a plurality of functions prepared in advance can be selected by rotating the changeover switch. The name of the currently selected function can be displayed on the display in real time. It is stated that the selected function can be executed by operating the selection switch. Reference 2 does not mention the color selection function, but it can be applied to color selection. In this case, one of a plurality of colors prepared in advance is selected by rotating the changeover switch, the name of the selected color is displayed on the display unit, and when the selection switch is operated,
The selected color will be valid.

[0006]

Although an input pen having a color selection function has been proposed in the past as described above, there are still problems to be solved.

The first problem is that it is impossible to know what kind of color the selected color actually is, by drawing it. There is no problem with popular colors such as black, red, blue, and green, but in the case of special colors, it is difficult to imagine the actual color from the name of the color.

The second problem, which is related to the first problem, is that it is difficult to intuitively grasp what kind of color the currently selected color was. For example, in Reference 1, since the user needs to remember which color was selected immediately before, when the user stands up for some reason and resumes work after resuming work, he forgets the color selected immediately before. If you do, you cannot check it without drawing it. Further, when the technology described in Document 2 is applied to the color selection function, it is possible to know which color is selected by the name of the color displayed on the display unit, but in the case of a special color, the name of the color is used. It is difficult to imagine the actual color.

The present invention has been proposed in view of such circumstances, and an object thereof is to provide a pen-type pointing device capable of intuitively recognizing what kind of color the selected color actually is. Especially.

[0010]

Specifically, it has a switch for selecting a color, a means for coloring a part of the pen with the selected color, and a means for notifying the external device of the selected color. Here, the external device is an information terminal device including a coordinate position detecting device and a color display device that displays an image at the position detected by the coordinate position detecting device. In this way, since the part of the pen shines in the selected color, the user can intuitively recognize what kind of color it is.

Further, the above-mentioned two switches are provided, and the color to be developed each time one of the switches is turned on and the color to be notified are changed in a predetermined order, and the color to be produced each time the other switch is turned on. The color to be notified may be changed in the opposite direction to the predetermined order. As a specific configuration for realizing this, a counter that counts up each time one of the switches is turned on and counts down each time the other switch is turned on, and color information according to the count value of the counter are provided. A color selector including a color information table to be output, a color generator that develops a color according to the color information output from the color selector, and the color information output from the color selector is notified to the external device. There is a configuration including a communication device.

The color selection switch 2 is a manual switch for selecting in advance the display color of the image to be pen-inputted to the information terminal device 8, and is composed of at least one switch. The output of the color selection switch 2 is guided to the color selector 3 by the signal line 10.

The color selector 3 is a circuit for selecting a color according to the operation of the color selection switch 2 by the user from a plurality of preset colors, and communicates with the color generator 4 through the signal line 11. It is connected to the container 5 by a signal line 12. When a certain color is selected, the color selector 3 instructs the communication device 5 through the signal line 12 that the information terminal device 8 should be notified of the selected color, and also indicates that the color should be developed. It is instructed to the instrument 4 through the signal line 11.

The color generator 4 is a portion that causes a part of the input pen to emit light in the color designated by the color selector 3. Which part of the input pen is colored is arbitrary and may be any part that can be recognized by the user.

The communication device 5 is a circuit for notifying the information terminal device 8 of the color instructed by the color selector 3. The communicator 5 and the information terminal device 8 may be wired by a cable or the like, or may be wirelessly connected. In the case of wireless connection, the communication device 5 converts the color data into a wireless signal or an infrared signal and transmits the wireless signal or the infrared signal to the information terminal device 8. For wired connection,
The communication device 5 transmits the color data to the information terminal device 8 via a cable or the like. In the case of wired connection, a cable for power supply is drawn between the input pen 1 and the information terminal device 8 in addition to the cable for signal transmission, and is supplied from the information terminal device 8 through the power supply cable instead of the power supply 6. It is also possible to adopt a configuration in which the generated electric power is supplied to each unit through the power supply line 9. In this case, the power switch 7 may be omitted.

When the input pen 1 according to the present embodiment configured as described above is used, a color can be selected on the pen side, and a part of the pen shines in the selected color. It is possible to intuitively recognize whether the color is like that.

Next, the information terminal device 8 will be described.
The information terminal device 8 includes a coordinate position detection device that detects a coordinate position designated by the input pen 1, a color display device, and a processing device that executes a drawing program that displays a color image at the detected coordinate position.

The communication unit 808 receives the color data notified from the communication device 5 of the input pen 1 and stores it in the color data storage area in the RAM 804. When the communication unit 808 is connected to the communication device 5 by wire, the communication unit 808 receives color data from the communication unit 5 via a cable or the like, and overwrites the color data storage area of the RAM 804. In the case of wireless connection, the color data obtained by decoding the wireless signal or infrared signal received from the communication device 5 is overwritten in the color data storage area of the RAM 804.

The information terminal device 8 generally operates as follows in relation to the input pen 1. When the pen tip of the input pen 1 contacts the tablet 810 and moves on the surface thereof, the tablet 810 sequentially outputs coordinate data corresponding to each contact position, and this coordinate data is input to the CPU 801 through the tablet controller 806.

Further, the color selector 301 connected to the LCD controller 403 by the signal line 11 by the microswitch 104c and the signal line 10, the color selector 301 is connected by the signal line 12, and the transmission antenna 105 is connected by the signal line 502. The wireless communication device 501 connected by the power supply 6 and the power supply 6 for supplying power to each part through the power switch 7 and the power line 9.
And are housed in the housing 102. The power supply 6 can be taken out by separating the upper housing 102-1 and the lower housing 102-2, and can be replaced or charged with a new one. In addition,
Transmission antenna 105, signal line 502, and wireless communication device 5
01 constitutes the communication device 5.

Referring to FIG. 5, the color selector 301 inputs a counter 302 connected to the microswitch 104c through the signal line 10 and a count value of the counter 302, and outputs color information corresponding to the count value to the signal line. The color information table 303 is sent to the LCD controller 403 through 11 and is sent to the wireless communication device 501 through the signal line 12. The counter 302 is initialized to a count value of 1 when the power is turned on, and thereafter, every time the microswitch 104c is turned on once, 2, 3, ...
Then, when the micro switch 104c is turned on in the state of the count value of 5, the cyclic counter returns to the count value of 1 again.

Referring to FIG. 6, the color information table 303.
Holds color information for each count value from 1 to 5. It should be noted that FIG. 6 additionally shows setting colors corresponding to each color information. In the case of FIG. 6, the set color is black when the count value is 1, red when 2, counts green when 3, counts blue when 4, counts white when 5, and each color information is red information, green information, It is specified by the combination of blue information.

The wireless communication device 501 is composed of an amplifier, a modulator, etc., converts the color information transmitted from the color selector 301 through the signal line 12 into a wireless signal, and transmits it from the transmitting antenna 105 to the information terminal device 8. Send. When receiving the color information, the communication unit 808 on the information terminal device 8 side overwrites the color data storage area of the RAM 804 as described above. The drawing program recognizes the current set color from the color information held in the color data storage area.

Next, the operation of the input pen 101 of this precondition example will be described. When the user turns on the power switch 7, the counter 302 of the color selector 301 is initialized to the count value 1, and the LCD controller 40 is read from the color information table 303.
3 and the wireless communication device 501, color information (RGB) = (00
0) is notified. The LCD controller 403 controls the color LCD 401 according to this color information, and makes the color of the display surface, that is, the coloring surface 103 on the head of the input pen 1, black. On the other hand, the wireless communication device 501 uses color information (RGB).
Since = (000) is transmitted to the information terminal device 8 by a wireless signal, the setting color on the information terminal device 8 side is also black.

After that, the user selects the color selection switch lever 1
When the micro switch 104c is turned on by pushing 04 once, the counter 302 of the color selector 301 counts up to 2 and the color information table 30
3 to LCD controller 403 and wireless communication device 50
1 is notified of color information (RGB) = (100). LC
The D controller 403 follows the color LC according to this color information.
By controlling D401, the coloring surface 103 on the head of the input pen 1 is colored red. In addition, the wireless communication device 501
Transmits color information (RGB) = (100) to the information terminal device 8 by a wireless signal, and the set color on the information terminal device 8 side is also red. Similarly, each time the user operates the color selection switch lever 104, the color of the color-developing surface 103 changes to green, blue,
White, black, red, ... Change, and the set color on the information terminal device 8 side changes accordingly.

In the above description, 5 of black, red, green, blue and white are used.
Although the types of colors have been set, there are a total of eight types of color information based on red information, green information, and blue information represented by 1 and 0, respectively, so that a maximum of eight types of colors can be set. Further, by using a color LCD capable of finely adjusting the brightness of red, green, and blue, it is possible to set more than eight colors. For example, when the brightness can be adjusted in 16 steps, the color information (RGB) can be set to a maximum of 16 × 16 × 16 colors from (000) to (161616). In Figure 7, black, red, pale red, purple,
An example of the color information table 303 when setting 10 types of blue, cyan, yellow, yellow-green, green, and white is shown. Here, the numerical values corresponding to red information, green information, and blue information indicate that the larger the value, the greater the degree of light emission. For example, a value of 15 indicates the highest degree of light emission, a value of 7 indicates that the light intensity is about half, and a value of 0 indicates that no light is emitted.

In the above-described precondition example, since the selected color is cyclically changed each time the color selection switch lever 104 is operated, one cycle is required to select the immediately preceding color. Therefore, if the number of selectable colors increases, it takes time to select a desired color. In the following, two premise examples will be described in which a desired color can be quickly selected even when the number of selectable colors is increased.

Referring to FIG. 8, an input pen 110 according to the second premise example has a color selection switch lever 104 and a color selection switch lever 11 near an upper portion of a pen-shaped casing 102.
This is different from the first premise example in that two color selection switch levers 1 are provided. As shown in FIG. 9, the newly provided color selection switch lever 111 is, like the color selection switch lever 104, rotatably supported about a shaft 111a and automatically biased by a spring 111b. It is a resettable lever. Further, a micro switch 111c which is turned on and off by this lever is provided. The output of the micro switch 111c is the signal line 10
It is input to the color selector 310 through a. Color selector 31
As shown in FIG. 10, a reversible counter of 0 is used as the counter 311, and counts up by 1 each time the microswitch 104c turns on and counts down by 1 each time the microswitch 111c turns on.
Other configurations are similar to those of the first premise example.

According to this precondition example, every time one of the color selection switch levers 104 is operated, for example, in the configuration using the color information table 303 of FIG. 7, black → red → pale red → purple → blue. → Cyan → Yellow → Yellow green → Green → White → Black, and every time the other color selection switch lever 111 is operated, in the opposite direction to the above, black → White → Green → Yellow green → Yellow → Cyan → Blue → purple → pale red → red → black changes. As a result, a desired color can be quickly selected even when the number of selectable colors is increased.

Referring to FIG. 11, the input pen 120 according to the third precondition is first precondition in that a slide switch 121 having a knob 121a near the top of the pen-shaped housing 102 is provided Is different from. As shown in FIG. 12, the knob 121a of the slide switch 121 is connected to the sliding contact 122a of the variable resistor 122 provided in the housing 102, and the variable resistor 122a
The voltage of the power supply 6 is applied to the color selector 320 through the power supply line 9, and the voltage corresponding to the position of the sliding contact 122a is supplied to the color selector 320 through the signal line 10. As shown in FIG. 13, the color selector 320 has an A / D converter 321 that converts an analog voltage applied through the signal line 10 into a digital value, instead of the counter 302 shown in FIG. This A
The output value of the / D converter 321 is output to the color information table 303 as a count value. Other configurations are similar to those of the first premise example.

According to this premise example, the slide switch 12
If the knob 121a of No. 1 is slid in one direction, for example, in the configuration using the color information table 303 of FIG. 7, black → red → pale red → purple → blue → cyan → yellow → yellow green → green →
If it changes from white to black and slides in the other direction, it changes in the opposite direction to black → white → green → yellow green → yellow → cyan → blue → purple → pale red → red → black. As a result, a desired color can be quickly selected even when the number of selectable colors is increased.

Although the slide switch 121 is used in the precondition example, a rotary switch may be used. In this case, the sliding terminal 122a of the variable resistor 122 is configured to interlock with the rotation of the rotary switch.

In each of the above-described preconditions , the coloring surface 103 is provided on the head of the input pen, but it is also possible to color the other portions of the input pen. For example, as shown in FIG. 14, the pen tip portion of the pen-shaped housing 102 is processed into a polyhedron, and the color LCD 131 is attached to each surface, whereby the pen tip portion can be used as a coloring surface. Also, as shown in FIG.
By sticking the color LCD 132 on one side or both sides of the color selection switch lever 104, the color selection switch lever 104 can be used as a coloring surface.

Next, the pen mold according to the first embodiment of the present invention.
The pointing device will be described. Each before on more than
In Hisage example, although using a color LCD color development device 4, the first
In this embodiment, red LED, green LED and blue LED are used.
It FIG. 16 shows an example of the structure of the color former in that case. FIG.
Referring to, the color generator 410 includes a red LED 411 and a green L
The red LED 411 and the green LED according to the red information, the green information, and the blue information in the color information transmitted from the color selector 3 through the signal line 11 and three types of LEDs of the ED 412 and the blue LED 413.
A color control circuit 414 for controlling the light intensity of the ED 412 and the blue LED 413, a translucent body 415 attached to the color surface of the input pen, and LEDs 411, 412, 413.
And an optical system 416 that guides the emitted light of (1) to the semitransparent body 415. The optical system 416 includes one or a plurality of optical fibers 417 each having one end connected to the semitransparent body 415 and each L
Light emitted from the EDs 411, 412, and 413 is sent to the optical fiber 41
7 and the optical lens 418 which is incident on the other end.

In the precondition example using the color information table 303 of FIG. 6 described above, the color control circuit 414 turns on the corresponding LED when the color information is 1, and turns off the corresponding LED when the color information is 0. . For example, color information (RG
When B) is red (100), only the red LED 411 is turned on. Then, only the red light emitted from the red LED 411 is transmitted through the optical system 416 to the translucent body 415.
, And the translucent body 415 glows red. When the color information (RGB) is white (111), all LEDs are
Light up. Then, the red, green, and blue lights are emitted by the optical system 4.
16 and the translucent body 415 are color-mixed, and the translucent body 415 glows white. Of course, it can be applied to the above-described precondition example using the color information table 303 of FIG.
In that case, the degree of light of the corresponding LED is controlled according to the numerical value of the color information. For example, if the color information (RGB) is (1
5,8,8) the light intensity of the red LED 411 is maximized and the green LED 412 and the blue LED 4 are light red.
13 shines about half of that.

When all the red, green, and blue LEDs are turned off, the translucent body 415 does not emit any color, so that the color of the object behind the translucent body 415 is semi-visible to the user's eyes. It is recognized as the color of the transparent body 415. Therefore, the translucent body 41
If a black film or the like is put on the back of 5, a black display is possible. FIG. 17 shows a configuration example of the semitransparent body 415 in that case. FIG. 17A is an external perspective view showing a configuration suitable for the case where the head of the input pen or the switch portion is used as the coloring surface, and the black film 4 is provided on the back surface of the flat translucent body 415.
19 is attached. Further, FIG. 17B is a cross-sectional view showing a state in which the outer shape of the semitransparent body 415 is processed into the shape of a pen tip, the inside is hollow, and the black film 419 is attached. To make the back surface of the translucent body 415 black, any method such as painting the back surface in black can be used in addition to attaching a black film .
