Referring to FIG. 1 , the touch chalk 100 of the present embodiment includes a chalk body 110 and an electrical conductor 120 , and the electrical conductor 120 is disposed on the chalk body 110 . The material of the chalk body 110 includes, for example, calcium carbonate or calcium sulfate. The chalk body 110 has opposite ends 112, 113. The outer surfaces 111, such as chalk, are held between the two ends 112, 113 of the chalk body 110. The body 110 is a cylinder, and the outer surface 111 between the ends 112, 113 is a cylindrical surface for the user to hold. The electrical conductor 120 of the present embodiment includes, for example, a conductive layer 121 covering at least the outer surface 111 between the two ends of the chalk body 110. That is, the conductive layer 121 may cover both ends 112, 113 of the chalk body 110, or either end of the ends 112, 113, in addition to the outer surface 111 of the chalk body 110. FIG. 1 is an example in which the outer surface 111 is covered with a conductive layer 121. The material of the conductive layer 121 includes at least one of silver paste and graphite, but the present invention is not limited thereto. The chalk body 110 is gradually worn out by friction during writing, and the conductor 120 is also worn out as the chalk body 110 is used.

The color of the chalk body 110 can be white, yellow, red, green, blue, or other colors. Since the conductive layer 121 is coated on the outer surface 111 of the chalk body 110, the conductor 120 may include a pigment (not shown) mixed with the conductive body 120 to form a color. Conductive layer 121. The pigment selected is, for example, the same color as the chalk body 110 to facilitate the user to recognize the color of the touch chalk 100. Moreover, when using the touch chalk 100 to write on the blackboard, the worn conductive layer 121 may also be attached to the blackboard together with the worn chalk body 110 to leave a writing handwriting on the blackboard, so the selected pigment and chalk body are selected. When the colors of 110 are the same, the color of the content written by the touch chalk 100 is relatively uniform.

2 is a schematic view of a touch chalk according to another embodiment of the present invention. Referring to FIG. 2 , the touch chalk 100 a of the present embodiment is similar to the above-described touch chalk 100 . The main difference is that the conductive body 120 a of the embodiment includes, for example, a conductive powder 121 a , and the conductive powder 121 a is uniformly mixed in the chalk body 110 . The material of the conductive powder 121a includes at least one of silver paste and graphite, but the present invention is not limited thereto.

The capacitive touch sensing layer 220 is disposed on the back surface 213 of the blackboard layer 211. The capacitive touch sensing layer 220 of the present embodiment is adhered to the back surface 213 of the blackboard layer 211 via the adhesive layer 230, for example. Since the touch chalk 100 has a conductive layer 121, when the user holds the touch chalk 100 and writes on the front surface 212 of the blackboard layer 211 using the touch chalk 100, the capacitive touch sensing layer 220 senses the touch chalk 100. The conductive layer 121 generates an inductive signal, and the capacitive touch sensing layer 220 generates an electronic handwriting according to the sensing signal and corresponding to the handwriting of the front surface 212 of the blackboard layer 211.

The electronic blackboard device 200 of the present embodiment further includes a processing component 221. The processing component 221 is electrically connected to the capacitive touch sensing layer 220 of the electronic blackboard 210 for receiving the sensing signal from the capacitive touch sensing layer 220. In this embodiment, the processing component 221 can be externally connected to the computer host 222, for example. When the touch chalk 100 generates an electronic handwriting corresponding to the sensing signal on the capacitive touch sensing layer 220, the computer host 222 can synchronously display the electronic handwriting on the screen (not shown), and can store the electronic handwriting. In this way, the written content can be digitized so that the listener does not have to distract the content written on the front side 212 of the blackboard layer 211.

The electronic blackboard device 200 of the embodiment may further include an electronic eraser for wiping the handwriting of the front surface 212 of the blackboard layer 211 and the electronic handwriting described above. 4 is a schematic diagram of an electronic eraser of an electronic blackboard device according to an embodiment of the present invention. Referring to FIG. 3 and FIG. 4 , the electronic eraser 300 of the present embodiment includes a eraser body 310 and a plurality of conductive elements 320 . The present embodiment is exemplified by three conductive elements 320 disposed at intervals inside the eraser body 310 . Specifically, the eraser body 310 has a wiping surface 311 for wiping off the handwriting of the touch chalk 100 written on the front surface 212 of the blackboard layer 211 of FIG. 3, and the conductive elements 320 are, for example, parallel to the wiping surface 311 and configured. Inside the eraser body 310. When the electronic board eraser 300 is used to wipe the front surface 212 of the blackboard layer 211, the capacitive touch sensing layer 220 of FIG. 3 senses the wiping trajectory of the conductive elements 320, and since the relative positions of the conductive elements 320 are fixed, Therefore, the processing element 221 can determine that this is a wiping action, and thus removes the electronic handwriting corresponding to the wiping trajectory according to the wiping trajectory of the conductive elements 320 moving on the front side 212 of the blackboard layer 211. The wiping range can be defined differently. For example, the wiping range may be defined as a triangular range R1 formed by the line connecting the conductive elements 320, or may be a circular range R2, which is, for example, centered on the geometric center of the triangular range R1.
