Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a brush for calligraphy.

[Background of the invention]

When writing characters with a calligraphy brush, a method is used in which the pressure of the pen is increased in certain parts of the character, and the pressure of the pen is decreased in other parts. Takumi is said to be my deciding factor.

However, for beginners, it is extremely difficult to adjust the amount of pressure applied by the user, and even if an experienced instructor verbally instructs the beginner how to adjust the amount of pressure applied while looking at the beginner's writing, it is difficult for beginners to understand because it is intangible. This cannot be done, and it is difficult for leaders to communicate this effectively. Therefore, the inventor of the present invention has focused on the fact that if the amount of adjustment of writing pressure can be learned in some concrete form other than verbally, it will be easier to understand and improve writing skills.

[Purpose of the invention]

The present invention is intended to display the state of pen pressure with sounds, graphs, numerical values, etc. on a display device, thereby helping the user actively learn how to adjust the pen pressure, and to speed up the improvement of calligraphy writing.

[Embodiment 1] (Figures 1 and 2) A brush tip 1 is provided on a brush shaft 2 so as to be movable in the axial direction. Specifically, a sliding piece 3 having a brush tip fitting shaft part 3a at the tip and an operating rod 3b protruding from the rear end is placed in the hollow part of the brush shaft 2, and has a slight sliding stroke l. The brush tip 1 is fitted into the fitting shaft portion 3a so as to prevent it from coming out, and protrudes toward the tip of the brush shaft.
The cylindrical portion 1a constituting the cylindrical portion 1a is detachably and replaceably fitted and connected, and the rear end contact 3c of the operating rod 3b is fixed within the pen shaft 2.The conductive pressure sensitive rubber 4 constituting the pen pressure detection means is Let me come,
and a pen pressure display device provided on the pen shaft 2 on the pressure sensitive rubber 4;
That is, in this example, a sounding body 5 consisting of a buzzer is connected via a control circuit 6 whose operation will be described later.

Note that E is a power supply battery, and in this example, two batteries of 1.5V and 4.5V are used. 7 is a power switch.

Next, the operation of the above configuration will be described. (FIG. 2) When the brush tip 1 is pressed against the paper drawing, the pressure-sensitive rubber 4 is compressed, thereby decreasing the resistance value and increasing the voltage at point P.

The Tel is -1c for Schmidt, and its input is P above.
When the potential at point P reaches the threshold level, the output of Iel becomes L level and the transistor T
rl is turned ON, and thereby the sounding element 5 sounds with one battery. (Sound is small) In the above state, the potential at point Q is divided by resistors R1 and R2, so the potential is lower than point P, the input of Ie2 is at L level, and therefore the output is at H level, and transistor Tr2
is OFF.

Therefore, if you press the tip of the brush more strongly in the previous state, the voltage at point P will rise, and the potential at point Q will also rise, and when re2 reaches its threshold level, the output of C2 will become L level, and transistor Tr2 will turn ON. Therefore, the sounding element 5 sounds with the 45V of the other battery. (The sound is loud) In the figure, R1 is a resistor for dividing the pressure with the pressure sensitive rubber, and R4 is a resistor for sensitivity adjustment. Further, in the above control circuit, an example is shown in which only 281 sounds are generated for states of weak and strong pen pressure, but a multi-stage sound generation circuit may be provided to display various pen pressure states. .

Further, although the above example is shown in which the sound is output in stages, it is of course possible to output the sound in a so-called linear manner that changes sequentially.

[Example 2] (Figure 3) Example B shows an example in which a sliding variable resistor 8 is used instead of the pen pressure detection means of Example 1, that is, the pressure-sensitive rubber. The brush tip 1 is urged to protrude by a spring 9, and the change in resistance caused by pushing the brush tip against the spring 9 operates the control circuit 6 of the tip, causing the sounding body 5 to sound.

[Embodiment 3] (Figures 4 and 5) Example B shows an example in which the pen pressure detection means is configured as a contact type, and the movable side contact I is attached to the displacing operating rod 3b together with the brush tip 1.
A fixed contact 11 is provided in the moving range of this contact 10.
．． 12 are arranged in this order, and the contact between the fixed contact 11 and the movable contact 10 creates a closed circuit of 1.5 V for the battery, and the contact between the fixed contact 12 and the movable contact 10 creates a closed circuit for the battery 4.5 V.
A closed circuit is formed respectively, and two large and small tones are emitted from the sounding body 5.

[Embodiment 4] (FIGS. 6 and 7) This example shows an example in which writing pressure is displayed using an external display device 13 that is separate from the writing brush. Therefore, first of all, as shown in FIG.
．． 1-chip microcomputer 16 with transfer switch 15. A memory output driver 182 is provided with a communication element 19 (LED in this example), while the external display device 13 is a receiving device 20 containing a phototransistor as shown in FIG. Computer for data analysis 21. It consists of a CRT display 22 or a printer 23.

Therefore, the operation is performed by digitizing the resistance change from the pressure-sensitive rubber 4 caused by the pressure of the brush tip, that is, the amount of displacement, by the human/D converter 14, and transmitting the data to the microcomputer 1.
Let G input. The microcomputer 16 samples input data at fixed times and stores the results in the memory 17. After writing a character, when the transfer switch 15 of the microcomputer 16 is pressed, the data stored in the memory 17 operates the communication element 19 via the output driver 18, and the signal is converted to the external display value [13 The reception is received by the receiving device 20 of. Data from this receiving device is input to a computer 21, analyzed, and output to a display 22 or printer 23, where a graph pattern is displayed, for example, as shown in FIG.

Therefore, the teacher looks at the pattern and critiques the pen pressure, or compares it with the teacher's standard pattern to help the student understand the amount of pen pressure.

[Embodiment 5] (Fig. 9) In this example, the receiving device 20 (not shown) shown in Fig. 7 is incorporated into the pen shaft 2 equipped with the circuit device shown in Fig. 6, and the receiving device 20 (not shown) shown in Fig. 7 is installed in the pen shaft. This is an example in which the pen pressure is displayed on the liquid crystal display device 24, and in this case, the displacement is displayed as an indicator.

[Embodiment 6] (FIG. 10) In this example, the reception device 20 of the external display device shown in FIG. display 2
An example of connection to 2 is shown.

Therefore, the action is to raise the brush 25 times after finishing writing the character.
When the pen is pressed in, the transfer switch 15 provided on the brush hits the bottom of the brush holder and the computer 21 analyzes the memorized data and displays the pen pressure on the display 22.

〔Effect of the invention〕

As described above, according to the present invention, when a character is written in the usual way, the pen tip is displaced by the pen pressure, and the pen pressure detection means captures the amount of displacement, operates the activation device, and displays the display device. It displays the state of the pen pressure, so beginners can easily learn how to adjust the pen pressure, which is important when writing, and it can also help speed up your writing skills. is big.
