Description

Electronic handwriting processing device

The present invention relates to a handwriting processing apparatus, and more particularly to a device for performing a process of eliminating/restoring a handwriting formed by a temperature-changing color-changing ink.

The current electronic eraser is mostly used to wipe the rubber with a motor rotation or vibration, and can only be used for pencil wiping. However, since the company developed the wipeable ballpoint pen using special inks, it has become popular and popular. The wiping method of the eraser attached to the special pen is the principle of rubbing the heat by the eraser, so that the ink is heated to a temperature greater than a certain temperature to achieve the discoloration effect of the ink. However, the wiping action often affects the quality of the paper, leaving wrinkles. In addition, if the paper quality is not ideal when wiping, there is often ink stuck in the fiber, so that the wiping effect is not ideal. In addition, the ink after wiping is also difficult to recover with an eraser.

Since the ink uses a temperature-changing color ink, when the temperature is higher than a certain temperature (for example, 70 degrees C), the ink becomes transparent. In this kind of ink, when the temperature is lower than a certain temperature (such as below -10 degrees), the ink will return to color. Using this feature, the present invention provides an electronic handwriting elimination/recovery device that replaces the traditional friction heat generation with temperature-changing electronic component processing, and uses the temperature-changing component to touch the handwriting to change the color of the handwriting, and not only allows the visible handwriting to be It becomes transparent by heating, and it is also possible to use a cooling element to change the already transparent handwriting back to a state of visible color. Such device Includes battery; temperature change element, which can be a resistance heater or peltier cooler, or both; power and / or function switching switch or contact sensor, can have heating and cooling Alternatively, only heating or cooling alone can be used to achieve different switching purposes by using a squeezing and temperature changing element. In addition, the temperature sensing component can be selectively configured, which can be the temperature changing component itself; and the control circuit can transmit the power source to the temperature changing component according to the state of the switch and the temperature sensing component; and the illumination device can emit ultraviolet light to be restored during the cooling operation. Handwriting. Therefore, the electronic handwriting processing device provided by the creation can not only replace the function of the traditional friction type brush eraser, but also expand the handwriting recovery function.

The electronic handwriting processing apparatus 1 provided by the present invention, as shown in Fig. 1, is for processing the handwriting 51 formed on the writing medium 5 by the above-described temperature-changing color-changing ink. First, a temperature change element 12 is provided. The temperature change element 12 is mounted on the electronic handwriting processing device 1 so that the temperature change element 12 can be changed in temperature under the user's operation (for example, the changeover switch 141). The temperature-changing color-changing ink on the handwriting 51 changes from visible to transparent, or from a transparent state to a visible color. By touching the temperature change element 12 to the writing medium 5, the purpose of handwriting elimination/recovery can be achieved.

Referring to FIG. 2, the electronic handwriting processing device 1 includes a power supply device 11 and a temperature change. Element 12, and power control device 14. The power supply device 11 is a battery or other power source, and the power supply control device 14 including an element such as the switch 141 controls the power supply state to the temperature change element 12. The temperature change element 12 is connected to the power supply unit 11 to change the temperature by the electric power supplied from the power supply unit 11, and is used to contact the handwriting 51 as shown in Fig. 1 to change the color of the handwriting from one color state to another color state. If the temperature change element 12 is a heating element, such as a resistive heating element, etc., it can be heated by the power supply device 1 to generate heat, so that the surface temperature of the temperature change element 12 can be changed to a state in which the touched hand is changed from a visible color state to a transparent state. The color change element 12 can be used to eliminate the color of the handwriting, and the electronic brush effect can be achieved.

Because of the temperature-changing color-changing ink introduced by Baile, when the temperature is higher than a certain temperature (such as 70 degrees C), it will become transparent, and when the temperature is lower than a certain temperature (such as below -10 degrees), the ink will be Will restore the color. For such a characteristic, the temperature change element 12 can also be a refrigeration element, so that the ink handwriting that has become transparent can be restored to the original visible color by the cooling effect of the temperature change element 12. The cooling element may be a peltier cooler containing a heat sink or a fan or the like. The current technology can make the size of the Peltier cooling fins a few millimeters (mm) square, and when the current of 0.7A is applied, the temperature difference of 40 degrees Celsius or more can be caused, so that the function of restoring handwriting can be achieved. .

Since the handwriting after being heated becomes transparent and it is difficult to identify the position thereof, as shown in FIG. 3, the electronic handwriting processing apparatus 1 can be selectively provided with the illumination device 13, which provides a handwriting that can be transparently illuminated. It becomes a visible light source to show where the handwriting is located. Generally, a light source having a wavelength of less than 380 nm, such as a UV light LED, can display a scratched ink mark to help restore the handwriting.

As previously mentioned, the temperature change element 12 can be a heating element or a refrigeration element. however, For operational convenience and functional comprehensive requirements, as shown in FIG. 3, the temperature change element 12 may also include the heating element 12a and the cooling element 12b. In order to be able to switch between heating and cooling functions, a function switching element 16 is arranged between the temperature change element 12 and the power supply unit 11. The function switching element 16 can be a three-stage switching switch (closed/positive/reverse), or a capacitive or optical contact sensor to control the on/off and heating/cooling of the temperature change element 12. Switching between functions.

In order to cooperate with the configuration of the temperature sensing element 15, the power control device 14 may include a control circuit 142 that connects the temperature sensing element 15 and the power supply unit 11. In addition, the function switching element 16 connected to the control circuit may be the aforementioned switch 141, or a capacitive or optical contact sensor or the like. Under such a configuration, the control loop 142 can control the amount of power supplied to the temperature change element 12 by the power supply unit 11 according to the state of the function switching element 16 and the temperature sensing element 15, thereby achieving the purpose of turning on/off and controlling the temperature change element 12. In order to display the switched functional state, a functional display element 18 can be coupled to control loop 142. In the case where the control loop 142 is not disposed, as shown in FIG. 3, the function display element 18 may be connected to the function switching element 16. The functional display element 18 can be a number of LEDs or other components that are sufficient to distinguish between functional states such as on/off/heating/cooling.

As shown in Figures 3 and 5, the contact element 17 can be mounted on the temperature change element 12 to provide a preferred contact interface between the temperature change element 12 and the writing medium 5 in which the handwriting 51 shown in Figure 1 is located. . The contact member 17 can be made of a heat-resistant/cold-resistant, heat-conducting material to facilitate heat exchange between the temperature change element 12 and the surface of the writing medium 5. The temperature sensing element 15 may be disposed on the contact element 17 as shown in FIG. 5, in addition to being directly disposed on the temperature change element 12.

In summary, the creation uses the handwriting element of the variable temperature element to contact the temperature-changing color-changing ink, thereby eliminating or restoring the handwriting, which not only replaces the traditional friction-type brush eraser, but also solves various disadvantages caused by the application of the pen-brush. It can achieve the handwriting recovery function that the traditional pen erase can't do, and it has greatly improved in terms of use effect, function and operation convenience.
