DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 is a pen input device for inputting with a pen on a tablet arranged corresponding to a display section for displaying various information and images, wherein the pen has a light emitting means. The light emitting means emits light corresponding to the color of the pen input selected on the tablet. With this configuration, the input color can be confirmed with the pen in hand without looking at the menu on the display screen.

According to a second aspect of the present invention, in the first aspect of the present invention, there is provided a pen input device for changing a light emission amount of a light emitting means in accordance with a line width of a pen input selected on a tablet. You can check the line width of the input with your pen without looking at the menu on the display screen.

According to a third aspect of the present invention, in the first aspect of the present invention, there is provided a pen input device for changing a light emitting period of a light emitting means in accordance with a broken line interval of a pen input selected on a tablet. The user can check the interval between broken lines with the pen in hand without looking at the menu on the display screen.

(Embodiment 1) FIG. 1 is a conceptual diagram of a pen input device according to Embodiment 1 of the present invention, and FIG. 2 is a block diagram showing a configuration of the pen.

As shown in FIG. 1, a menu for selecting a pen input function is displayed on a display screen 1 integrated with a tablet. In this menu, 2a is a menu for selecting the line width of the pen to be input, 2b is a menu for selecting the color of the pen to be input, 2c is a menu for selecting the interval between broken lines of the pen to be input, and 2d is the direction of the arrow (the direction of the arrow). Is a menu for selecting. Using the pen 3, the user selects a pen color, line width, broken line interval, etc. from a menu on the display screen 1 and performs pen input on the actual display screen 1.

In FIG. 2, a pen 3 has a red LED 4a, a green LED 4b, and a blue LED 4c as light emitting means.
And an LED control unit 5 for controlling the light emission, a detection head 7 for detecting a signal for calculating coordinates from the electrostatically coupled tablet, and noise removal and amplification for the signal detected by the detection head 7. A detection signal processing unit 6, a signal processed by the detection signal processing unit 6, a signal for controlling the LED control unit 5, and an interface unit 8 for interfacing a power supply and a ground with a main control unit (not shown);
It is composed of

The operation of the pen input device according to the present embodiment configured as described above will be described. First, a signal for calculating coordinates is generated from the tablet. Next, this is detected by the detection head 7, noise removal and amplification are performed on the signal detected by the detection signal processing unit 6, sent to the main control unit via the interface unit 8, and transmitted to the main control unit. The coordinates where the pen is placed are calculated based on the leverage signal. The main control unit repeats the same operation to calculate the coordinates of the trajectory of the pen 3, and at the same time updates the display content based on the calculated coordinates to perform pen input.

On the other hand, when the color of the pen input is to be set (here, it is set to red), the pen 3 is moved to the column of R shown in the menu 2b on the display screen 1 and clicked here. Here, the clicked coordinates are calculated by the tablet and the main control unit integrated with the display screen 1. The main control unit knows that the calculated coordinates are the coordinates for setting the input color of the pen to red, so that the R column is changed to a display indicating that the selected color is selected.
The input pen 3 has an LED via the interface unit 8.
A command to control the emission of the red LED is issued to the control unit 5. Based on this, the LED control unit 5 causes the red LED to emit light. Here, the electrostatic coupling method has been described as a tablet, but a pressure-sensitive method, an electromagnetic induction method,
An ultrasonic surface acoustic wave system or the like may be used.

As described above, in the pen input device according to the present embodiment, when the color of the pen to be input is set, not only the setting is displayed on the display screen 1 but also the pen 3 is set. Since the color is emitted, the color of the pen to be input can be easily confirmed just by looking at the pen.

(Embodiment 2) FIG. 3 is a diagram showing the relationship between the line width of an input pen and the LED light emission luminance according to Embodiment 2 of the present invention. Note that the configuration and basic operation of the pen input device are the same as those in the first embodiment, and thus are omitted here.
Set the line width of the pen to be entered (the pen color is red)
The operation will be described.

First, the pen 3 is moved to the column 2a in the menu on the display screen 1 and clicked here to select the line width of the pen to be input. The main control unit knows that the clicked coordinates are the coordinates for setting the line width of the pen to be input. Therefore, the column of 2a is changed to a display indicating the selected line width, and the pen 3 A control command is issued to the LED control unit 5 via the interface unit 8 to emit the red LED at a luminance corresponding to the line width of the selected input pen shown in FIG. Based on this, the LED control unit 5 causes the red LED to emit light at a predetermined luminance.

As described above, in the pen input device of this embodiment, when the line width of the pen to be input is set, not only the set line width is displayed on the display screen 1 but also the pen 3 is displayed. The brightness corresponding to the set line width, for example, if the line width is thick, the light will be brighter, and if the line width is thin, the light will be emitted darker. You can check.

(Embodiment 3) FIG. 4 is a diagram showing a relationship between the interval between broken lines of a pen and the LED lighting frequency according to Embodiment 3 of the present invention. Since the configuration and basic operation of the pen input device are the same as those in the first embodiment, they are omitted here, and the operation of setting the interval between broken lines of the pen to be input (the color of the pen is red) will be described. .

First, the input pen 3 is moved to the column 2c in the menu on the display screen 1 and clicked here to select the interval between broken lines of the pen to be input. The main control unit knows that the clicked coordinates are the coordinates for setting the broken line interval of the pen to be input. Therefore, the column 2c is changed to display indicating the selected broken line interval, and the pen 3 is displayed. A control command for emitting a red LED at a frequency corresponding to the interval between the dashed lines of the selected pen shown in FIG.
Based on this, the LED control unit 5 causes the red LED to emit light at a predetermined frequency.

As described above, in the pen input device according to the present embodiment, when the interval between the broken lines of the pen to be input is set, not only the set interval of the broken line is displayed on the display screen 1 but also the pen 3 is displayed. Frequency corresponding to the set broken line interval,
That is, when the input is a solid line, the LED is controlled to be ON (light emission) and OFF (extinction) in accordance with the DC and further according to the interval between the broken lines, so that the interval between the broken lines of the pen to be input can be easily confirmed just by looking at the pen. .

[0023]

As described above, according to the present invention, the color of the pen to be input can be confirmed not only on the display screen to be set but also with the pen. You can check the color. According to the present invention, not only on the display screen for setting the check of the thickness of the pen input, but also with the input pen, it is possible to check the thickness of the pen to input naturally without discomfort for the person performing the pen input. I can do it.

Furthermore, according to the present invention, not only on the display screen for setting the confirmation of the interval between the broken lines of the pen input but also with the input pen, the interval between the broken lines of the pen can be naturally input to the person who performs the pen input without any discomfort. Can be confirmed.
