Abstract

A selector pen for touch screen includes a barrel, a light emitter mounted in the barrel, a switch connected to a rear end of the barrel for turning on or off the light emitter, and a transparent head connected to a front end of the barrel. When a user needs to use a touch screen in a dim environment, he or she may operate the switch for the light emitter to emit light that passes through the transparent head to illuminate a space surrounding the selector pen and thereby enables the user to easily select function options on the touch screen with the selector pen.

Claims

1. A selector pen for touch screen, comprising a barrel, a light-emitting means mounted in said barrel, a switch connected to a rear end of said barrel for turning on or off said light-emitting means, and a transparent head connected to a front end of said barrel, whereby light emitted from said light-emitting means passes through said transparent head to illuminate a space surrounding said selector pen.

2. The selector pen for touch screen as claimed in claim 1, wherein said switch is a turn switch.

3. The selector pen for touch screen as claimed in claim 1, wherein said switch is a push switch.

4. The selector pen for touch screen as claimed in claim 1, wherein said light-emitting means includes a circuit board and a battery.

5. The selector pen for touch screen as claimed in claim 4, wherein said circuit board is provided at an end with means for electrically connecting said circuit board to positive and negative electrodes of said battery, and at another end with a light-emitting diode.

6. The selector pen for touch screen as claimed in claim 4, wherein said circuit board includes a voltage booster circuit to enable stable emission of light from a special light-emitting diode.

7. The selector pen for touch screen as claimed in claim 5, wherein said means for electrically connecting said circuit board to said battery include a big and a small spring connectable to said positive and said negative electrodes, respectively, of said battery.
