Abstract

PURPOSE:To use a stylus pen in the same use as that of a writing tool where 2 types of writing means are unified by providing the touch detecting parts at plural areas including the stylus pen point. CONSTITUTION:A stylus pen 1 includes the touch detecting parts 1c and 1d, and the ON/OFF signals of these parts 1c and 1d are transmitted to a signal generating part 1b. The part 1b produces a signal to show the touched one of both parts 1c and 1d, and this produced signal is sent to a touch signal receiving part 2a of a handwritten input device main body part 2 through a touch signal transmitting part 1a. When a handwritten input operation is carried out at a pen point touch detecting part 1c, a control part 2c processes the input as the one that is carried out by an eraser when the handwritten input operation is carried out a head touch detecting part 1d respectively. In such constitution, the pen 1 can be used in such a way as that applied when a handwriting operation is carried out on the paper by means of a pencil having an eraser at its head.

can perform more processing. However, even in this case, the handwriting result is displayed only when the tip of the stylus pen touches the tablet, and it does not work when touching the tablet with other parts of the stylus pen. There have been problems such as the stylus pen not being able to be used in the same way as a writing instrument that combines two or more types of writing means, such as a pen whose thickness can be changed.

This invention was made to solve the above-mentioned problems, and it allows the selection of pen/eraser and pen thickness from the stylus pen side, as well as a pencil with an eraser and a pen that can change the thickness. To provide a handwriting input device that allows a stylus pen to be used in the same way as a conventional writing instrument having two or more types of writing means.

[Means for Solving the Problems] A handwriting input device according to the present invention attaches touch detection sections to a stylus pen at a plurality of parts including the pen tip, and sends a signal indicating which touch detection section is detecting a touch. The signal generating means to be generated is attached to a stylus pen, and (1) the control section of the main body of the handwriting input device is provided with a function of processing according to the type of signal.

[Operation] The stylus pen according to the present invention has a plurality of touch detection sections, and the ON/OFF signals of these touch detection sections are transmitted to the signal generation section within the stylus pen, and the signal generation section determines which touch detection section is touched. A touch signal transmitter in the stylus pen transmits the generated signal to a touch signal receiver in the main body of the handwriting input device. The control section of the main body of the handwriting input device performs processing depending on the type of this signal.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
In the figure, +1) is the stylus pen, (2) is the main body of the handwriting input device, (1c) is the touch detection unit that is attached to the tip of the stylus pen (1) and detects whether the pen tip has been touched. Touch detection unit flb attached to the head of the stylus pen (1) and detecting whether the head has been touched
(1a) is a signal generation unit that generates different signals depending on ON/OFF signals from the touch detection unit (lc) and the touch detection unit (ld), and (1a) is a touch signal transmission unit that transmits the signal generated by the signal generation unit (lc). (2a) is the touch signal transmitting part of the stylus pen (1) [
A touch signal receiving unit (2) that receives the signal transmitted by 1al

Next, the operation will be explained.

The user presses the tablet (
2b) When inputting handwriting on the top, the evening/Sochi detection section (IC) is turned on by touch and transmits an ON signal to the signal generation section flb). The signal generating section (1b) generates a signal including this information by turning ON the signal from the touch detecting section (IC) of the pen tip and turning OFF the signal from the touch detecting section (1d) of the head. For example, if this signal is expressed in 2 bits, a signal of "lO" is generated in this case. Evening/Sochi signal transmitter (lal is the signal generator [1
This signal “lO” generated by b) is sent to the touch signal receiving unit (
2a).

On the other hand, the tablet (2b) detects the coordinates touched by the user. The control unit (2C) includes a touch signal receiving unit (
Based on the received signal "16" of 2a), it is determined that the user is inputting handwriting with the tip of the stylus pen, and the display unit (2d) uses the coordinates detected by the tablet (2b) to display the result of handwriting with the pen. to be displayed.

Further, when the user performs handwriting input on the tablet (2b) using the head of the stylus pen (1), the touch detection unit (ld) is turned on and an ON signal is sent to the signal generation unit (lb). introduce. In the signal generation unit (lb), the signal from the touch detection unit (IC) of the pen tip is turned OFF, and the signal from the touch detection unit (ldl) of the head is turned ON, so that a signal containing this information is generated as, for example, “01”. The touch signal transmitter (1a) transmits the signal "01" generated by the signal generator (lb) to the touch signal receiver (2a).

On the other hand, the tablet (2b) detects the user's touch coordinates. The control unit (2c) includes a touch signal receiving unit (2a).
It is determined that the user is inputting handwriting with the head of the stylus pen based on the reception signal "01" of the tablet (
The coordinates detected by step 2b) are displayed on the display unit (2d) as a handwritten result using an eraser, for example.

In this way, when the user performs handwriting input with the tip of the pen, the control unit (2c) processes it as input using the pen, and when the user performs handwriting input with the head of the pen, it is processed as input using the pen. For example, as an input using an eraser, the control unit (2c)

Treatment can be performed depending on the location.

As described above, in the above embodiment, handwriting input is possible using a stylus pen that has a plurality of touch detection sections and transmits a signal indicating which of the eight touch detection sections has been touched, and a reception section that receives signals from the stylus pen. A handwriting input device has been described that includes a tablet, a control unit that processes signals received by the reception unit and coordinate data detected by the tablet, and a display unit that displays the results processed by the control unit.

In the above embodiment, the stylus pen [1] is shown as having touch detection means attached to two places at the tip and head of the pen, but of course more touch detection means may be provided. For example, in Figure 2, a touch detection part is attached to the head of a stylus pen [1], and a touch detection part (21) for a thick lead and a touch detection part for a thin lead are attached to the tip of the pen. (22) can be attached, and input results using an eraser and pens of two different thicknesses can be displayed on the display section (2d) depending on the area touched on the tablet (2b). The signals generated in this case are, for example, as follows.

Touch detection part for thick lead...10 Touch detection part for thin lead...11 Touch detection part on Ben's head...
・・01 None touched・・No generation or 00 Also,
The stylus pen (1) shown in Section 3 has a
A touch detection unit (mf311) for the black line, a touch detection unit (32) for the red line, and a touch detection unit (33) for the ll' line are attached as touch detection units, and either touch detection unit is attached to the head of the pen. It is equipped with a knock-type mechanism that selects the pen tip, closes it, and sends it out. In addition, it is not a knock-type mechanism,
A rotary mechanism may be used to select the pen tip. Furthermore, FIG. 4 shows touch detection sections (4
This shows an example in which 1) and (42) are installed.

Further, FIG. 5 shows an example in which a single stylus pen is constructed by stacking small pens each having a touch detection section attached to their tips.

Further, there are various methods for the tablet (2b), such as an electrostatic induction method, an electromagnetic transfer method, and a resistive film method, but the handwriting input device of the present invention can be realized regardless of the tablet method. However, in the electrostatic induction method and electromagnetic transfer method, the stylus pen sends a signal for the tablet to detect the coordinates, so these methods have a function that sends the signal for coordinate detection to each touch detection part of the stylus pen. It is necessary to have

[Effect of the invention 1 As described above, according to the present invention, the stylus pen has a plurality of touch pressure detection sections, and the detection signals from the touch detection sections enable various processing to be performed in the main body of the handwriting input device.
