FIGS. 1A and 1B are perspective views, showing acapacitive stylus 1 according to an embodiment of the present invention. In this preferred embodiment, thecapacitive stylus 1 is used as an inputting device of a touch sensitive device (not shown), such as a mobile phone, a tablet personal computer, or the likes. The touch sensitive device may include a touch screen or include in-cell photo sensors, so that the touch events and touch positions of the user can be detected. In an embodiment of the present invention, the touch sensitive device includes, but is not limited to, a capacitive touch screen. - Referring to
FIGS. 1A and 1B , thecapacitive stylus 1 comprises apen 10 and adetachable eraser 12. The front end of thepen 10 includes atip 101 and thepen 10 itself can function as a typical capacitive stylus, i.e., writing on a screen of the touch sensitive device via thetip 101 and emitting a signal via thetip 101 or via other electrodes, so that the touch sensitive device receives the signal and performs one or more operations according to the signal. In addition, the rear end of thepen 10 has afirst connector 102, the front end (first end) of theeraser 12 has afirst connector 122, and the rear end (second end) of theeraser 12 has anemitting electrode 121. When thefirst connector 102 of thepen 10 combines with thefirst connector 122 of theeraser 12, and the second end (rear end) of theeraser 12 is compressed, e.g., compressed against the screen of the touch sensitive device, then thecapacitive stylus 1 will emit an erasing signal via theemitting electrode 121. Such that the touch sensitive device will receive the erasing signal and perform the erasing operation, e.g., erasing the handwriting within a predetermined area around theemitting electrode 121. -

Referring toFIGS. 1A and 2 , thepen 10 of thecapacitive stylus 1 may comprise acontrol circuit 103 and abattery 104, which provides electricity to thecontrol circuit 103. In addition, thedetachable eraser 12 of thecapacitive stylus 1 may comprise anerasing circuit 123 and an emittingelectrode 121. When thefirst connector 102 of thepen 10 combines with thefirst connector 122 of theeraser 12, theerasing circuit 123 will electrically connect with thecontrol circuit 103 of thepen 10. At this situation, if the user compresses the second end theeraser 12 against the screen of the touch sensitive device, then thecapacitive stylus 1 will emit an erasing signal via theemitting electrode 121. Such that the touch sensitive device will receive the erasing signal and perform the erasing operation, e.g., erasing the handwriting within a predetermined area. Notice that thebattery 104 within thepen 10 provides the electricity needed for emitting the erasing signal. -
FIGS. 3A and 3B illustrate aneraser 12 according to an embodiment of the present invention. Referring toFIGS. 3A and 3B , the first end of theeraser 12 may include afirst connector 122, and the second end of theeraser 12 may include asecond connector 125. In addition, aswitch 126 may be arranged within theeraser 12 and arranged near to thesecond connector 125. The mentioned emitting electrode 121 (not shown) may be arranged at thesecond connector 125 or may be arranged within theeraser 12. Referring toFIG. 1 ,FIG. 2 , andFIG. 3A , when thefirst connector 102 of thepen 10 combines with thefirst connector 122 of theeraser 12, the erasingcircuit 123 will electrically connect with thecontrol circuit 103 of thepen 10. Thesecond connector 125 may be omitted in another embodiment of the present invention. - Referring to
FIG. 3B , the erasingcircuit 123 of theeraser 12 may comprise, but is not limited to, an inductance L, a diode D1, a firs resistance R1, an emittingelectrode 121, a second resistance R2, a first field-effect transistor F1, and a second field-effect transistor F2. The first end of the inductance L connects with power supply VCC, and the second end of inductance L connects with the first end of the diodes D1 and the drain of the first field-effect transistor F1. Typically the power supply VCC is an external power and the power is provided by thebattery 104. The power supply VCC could be an independent power supply and is arranged within theeraser 12 in another embodiment of the present invention. In addition, the second end of the diode D1 connects with the first end of the first resistance R1, and the second end of the first resistance R1 connects with the emittingelectrode 121. When thefirst connector 102 of thepen 10 combines with thefirst connector 122 of theeraser 12, the gate of the first field-effect transistor F1 connects with thecontrol circuit 103 and the gate of the second field-effect transistor F2 connects with thecontrol circuit 103. The source of the first field-effect transistor F1 is grounded. Thecontrol circuit 103 may comprise a micro control unit.

FIG. 3A andFIG. 3B , when the second end of theeraser 12 is compressed, e.g., thesecond connector 125 being pressed against the screen of the touch sensitive device, then thesecond connector 125 is moving inwardly, so that aplug 1250 or ablock 1250 of thesecond connector 125 collides with theswitch 126 and results in theswitch 126 being switched to an ON position. By doing so, theswitch 126 electrically connects with thecontrol circuit 103, and thecontrol circuit 103 employs the emittingelectrode 121 to emit an erasing signal. The touch sensitive device receives the erasing signal and performs the erasing operation. - Because both the
pen 10 and theeraser 10 can emit signals to the touch sensitive device, the touch sensitive device needs to recognize the signal is emitted from which one device. Generally, the two types of signals can be design to have different frequency, modulation, emitting period, and/or different information transmitted in a digital manner, so that the touch sensitive device can recognize that the received signal is emitted from thepen 10 or emitted from theeraser 12. And then the touch sensitive device transmits the received signal or information to a controller to perform writing, erasing, or other operations corresponding to the received signal or information. - In the embodiment of
FIG. 3B , the erasingcircuit 123 merely comprises a signal outputting circuit (L, D1, R1, R2, F1, F2, and 121) for emitting the erasing signal. In another embodiment of the present invention, the erasingcircuit 123 may further comprise a signal inputting circuit for receiving signals from the touch sensitive device via the emittingelectrode 121. - In addition, in another embodiment of the present invention, the erasing
circuit 123 merely comprises the emittingelectrode 121, and the other components of the signal outputting circuit (L, D1, R1, R2, F1, and F2) are arranged at thecontrol circuit 103 of thepen 10. Further, in another embodiment of the present invention, the erasing signal is not actuate by theswitch 126, i.e., theswitch 126 being omitted. Instead of using theswitch 126, the erasing signal is continuously emitting from the emittingelectrode 121 when thefirst connector 102 of thepen 10 combines with thefirst connector 122 of theeraser 12. -
FIG. 4 is a block diagram showing aneraser 12 of thecapacitive stylus 1 according to another embodiment of the present invention. The erasingcircuit 123 of theeraser 12 has the same components as shown inFIG. 3B and further comprises an independent micro control unit MCU and an independent power supply VCC. Therefore, in this embodiment theeraser 12 itself can emit the erasing signal even if theeraser 12 is not combined with thepen 10. - The shape of the
first connector 122 of theeraser 12 and thefirst connector 102 of thepen 10 are not limited and may have other configurations.FIGS. 5A and 5B are perspective views showing a capacitive stylus according to another embodiment of the present invention. In this embodiment, thefirst connector 122 of theeraser 12 includes a recess, and thefirst connector 102 of thepen 10 has a plug fitting for the recess of thefirst connector 122.
