Abstract

A double head stylus having light pointer includes a tube having a conductive rubber stylus on both ends thereof. A least a conductive portion electrically connected to both the conductive rubber styluses is formed to the tube. Through holding the conductive portion of the tube by hand, both the rubber styluses of the tube are capable of performing capacitive sensing on a capacitive touch panel. One of the conductive rubber styluses has an axial through hole. A light pointer having at least one light source is arranged inside the tube so that the light of the light source will project from the through hole of the conductive rubber stylus as a pointer. A battery and circuit connected between the battery and the light source are arranged inside the tube. A switch serving to control the conductivity between the light source and the battery is arranged to the tube so as to control the operation of the light pointer.

Claims

1. A double head stylus having light pointer comprising:

a tube having a conductive rubber stylus on two ends thereof;

the tube having at least a conductive portion electrically connected to the two conductive rubber styluses;

each conductive rubber stylus connected to user'"'"' s hand through the conductive portion causing a capacitive sensing on a capacitive touch panel.

2. The double head stylus having light pointer as claimed in claim 1 further comprising:

an axial hole axially formed to one the conductive rubber styluses of the tube;

at least one light source arranged inside the tube near the axial hole of the conductive rubber stylus;

the light of the light source being projected ahead through the axial hole as a pointer;

a battery arranged inside the tube;

the battery being electrically connected to the light source through a circuit to provide power to the light source;

a switch arranged to the tube;

the switch controlling the connectivity between the battery and the light source so as to control the operation of the light source;

wherein the tube has two conductive rubber styluses and at least one light source so as to have both stylus and pointer functions at the same time.

3. The double head stylus having light pointer as claimed in claim 2, wherein the light source is one of a laser diode, LED, or other optic source.

4. A double head stylus having light pointer comprising:

a tube having a pen body and a cap;
