However, since the Pilot company has developed a wipeable ballpoint pen using special ink, it has become very popular and has become more and more popular. The wiping method of the eraser attached to this special pen is to use the principle of heat generated by the friction of the eraser to heat the ink to a certain temperature to achieve the effect of ink discoloration. However, this wiping action will often still affect the quality of the paper and leave wrinkles. In addition, if the paper quality is not ideal when wiping, ink will often get stuck in the fibers, making the wiping effect not ideal.

Detailed ways

The electronic handwriting processing device 1 provided by the utility model, as shown in FIG. 1 , is used to process the handwriting 51 formed on the writing medium 5 by the aforementioned temperature-changing and color-changing ink. At first a temperature variable element 12 will be provided, and this temperature variable element 12 is installed on the electronic handwriting processing device 1, so that the temperature variable element 12 can change the temperature under the user's operation (for example, switch 141), reaching enough to make the user The temperature-changing color-changing ink on the handwriting 51 changes from visible color to transparent, or changes from transparent state to visible color. When the temperature-changing element 12 contacts the writing medium 5, the purpose of erasing/restoring the handwriting can be achieved.

Please refer to FIG. 2 , the electronic handwriting processing device 1 includes a power supply device 11 , a temperature changing element 12 , and a power control device 14 . The power supply device 11 is a battery or other power supply, and the power supply state to the temperature variable element 12 is controlled by the power supply control device 14 including a switch 141 and other components. The temperature-changing element 12 is connected to the power supply device 11 to change the temperature by using the electric energy supplied by the power supply device 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 variable element 12 is a heating element, such as a resistance heating element, etc., it can be powered by the power supply device 1 to generate heat, so that the surface temperature of the temperature variable element 12 can reach a level that allows the touched handwriting to change from the state of visible color to transparent. , just can eliminate handwriting color by temperature-changing element 12, and reach the brush effect of electronic formula.

Because the temperature-changing color-changing ink introduced by Baile Company will become transparent when the temperature is higher than a certain temperature (such as 70 degrees Celsius), and when the low temperature is lower than a certain temperature (such as below -10 degrees Celsius), the ink will be transparent. Will restore color. In view of this characteristic, the temperature-variable element 12 can also be a cooling 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-variable element 12 . The cooling element can use a Peltier cooler, including its heat sink or fan. The current technology can make the size of the Peltier cooling sheet several millimeters (mm) square, and when a current of 0.7A is passed through, it can cause a temperature difference of more than 40 degrees Celsius. Therefore, the function of restoring handwriting can be achieved .

Since the handwriting after heating becomes transparent, it is difficult to identify its location, so as shown in Figure 3, the electronic handwriting processing device 1 can be optionally equipped with an illumination device 13, which can provide the handwriting in a transparent state after being irradiated. A light source that becomes visible to show where the ink is located. Generally, a light source with a wavelength of less than 380nm, such as an ultraviolet light emitting diode (UV light LED), can display ink marks that have been wiped, which is helpful for restoring handwriting.

As mentioned above, the temperature variable element 12 can be a heating element or a cooling element. However, for convenience in operation and comprehensive functions, as shown in FIG. 3 , the temperature variable element 12 may also include a heating element 12a and a cooling element 12b at the same time. In order to be able to switch between the two functions of heating and cooling, a function switching element 16 is arranged between the temperature changing element 12 and the power supply device 11 . The function switching element 16 can be a three-stage switching switch (off/positive connection/reverse connection), or a capacitive or optical contact sensor, etc., to control the on/off and heating/cooling of the temperature variable element 12 Toggle between functions.

As shown in Figures 4 and 5, in order to more accurately control the temperature of the temperature-varying element 12, the electronic handwriting processing device 1 can optionally configure a temperature-sensing element 15 on the temperature-varying element 12 to sense the temperature of the temperature-varying element 12 . In order to match the configuration of the temperature sensing element 15 , the power control device 14 may include a control loop 142 connected to the temperature sensing element 15 and the power device 11 . In addition, the function switching element 16 connected to the control loop can be the aforementioned switch 141 , or a capacitive or optical touch sensor and other elements. With such a configuration, the control circuit 142 can control the power output from the power supply device 11 to the temperature variable element 12 according to the states of the function switching element 16 and the temperature sensing element 15 , so as to achieve the purpose of turning on/off and controlling the temperature variable element 12 . In order to display the switched function state, a function display element 18 can be connected to the control circuit 142 . In the case where the control circuit 142 is not provided, as shown in FIG. 3 , the function display element 18 may also be connected to the function switching element 16 . The function display element 18 can be several LEDs or other elements that are sufficient to distinguish and display functional states such as on/off/heating/cooling.

As shown in FIGS. 3 and 5 , a contact element 17 can be installed on the temperature-changing element 12 to provide a better contact interface between the temperature-changing element 12 and the writing medium 5 where the handwriting 51 shown in FIG. 1 is located. The contact element 17 can be made of heat-resistant/cold-resistant material with good heat conduction, so as to facilitate the heat exchange between the temperature-changing element 12 and the surface of the writing medium 5 . The temperature sensing element 15 can also be arranged on the contact element 17 as shown in FIG. 5 in addition to being arranged directly on the temperature changing element 12 .

To sum up, the utility model uses the handwriting written by the temperature-changing element to contact the temperature-changing color ink to eliminate or restore the handwriting. It can not only replace the traditional friction-type eraser, but also solve various problems caused by the application of this eraser. The disadvantage is that it can achieve the handwriting recovery function that the traditional eraser cannot do, and it has greatly improved the use effect, function and operation convenience.
