Abstract

A pen with a scanner pen head and a twist switch comprised of a writing pen, an upper penholder section, a twist switch and a light emission device; a chamber containing three gradations in the upper penholder section to receive penetration of a guide pin from a plunger in the upper penholder section with the lower end of the plunger linked to the upper end of the writing pen so to control the plunger to rise to retract or to descend to expose a refill for writing purpose.

Claims

1. A pen with a scanner pen head and a twist switch, comprised of a writing pen, an upper penholder section, a twist switch and a light emission device;

wherein,

the writing pen containing a retractable refill for writing purpose and a polygonal hole being provided in its upper end;

the upper penholder section accommodating the twist switch and the light emission device;

the twist switch comprised of a chamber provided in the upper end of the upper penholder section to accommodate a plurality of cells, a trough being provided in the side wall of the chamber to contain an L-shape conductor extending to the upper end of the upper penholder section and where below the chamber;

a proper spacing being provided between the bottom of the conductor and the bottom of the cells;

a plunger inserted into the upper penholder section having on its side wall to protrude a channel containing three gradations extending at a certain slot;

a polygonal pillar being adapted to the lower end of the plunger to control the L-shape conductor to rise or to descend to contact or disengage from the cells; and

the light emission device having two conductor pins provided at its lower end;

characterized by that the upper penholder section being inserted into the upper end of the writing pen;

the polygonal pillar at the lower end of the plunger in the upper penholder being inserted into the polygonal hole in the upper end of where the upper penholder section being inserted into the writing pen;

the plunger being driven by twisting the writing pen;

the light emission device being mounted in the upper end of the upper penholder section for one pin at the bottom of the light emission device to contact the conductor with another pin pressing against the positive electrode of the cell.

2. A pen with a scanner pen head and a twist switch as claimed in claim 1, wherein, the writing pen related to a hollow tube having in its upper portion provided in smaller diameter to receive insertion by the upper penholder where adapted with the polygonal hole;

a conic tip provided at its lower end; and

the conic containing a coil for a refill to penetrate through and become retractable into and out of the conic tip.

3. A pen with a scanner pen head and a twist switch as claimed in claim 1, wherein, the upper penholder section is comprised of an outer sleeve, a hollow upper penholder and a cap;

a caulking trough being provided in the upper end of the outer sleeve;

a clip being provided on one side of the upper penholder, a circular cap provided to the upper end of the upper penholder to secure the-light emission device in position;

the upper penholder inserted into the outer sleeve for the root of the clip to be merely inserted into caulking trough; and

the upper penholder accommodating the twist switch.

4. A pen with a scanner pen head and a twist switch as claimed in claim 3, wherein, a conic convergence light mask is provided inside the front of the cap to converge the light source.

5. A pen with a scanner pen head and a twist switch as claimed in claim 1, wherein, a nipple is provided at the bottom of the L-shape conductor in the twist switch to be conducted when contacting the bottom of the cells.

6. A pen with a scanner pen head and a twist switch as claimed in claim 1, wherein, the light emission device related to a transparent or opaque bulb or LED.

7. A pen with a scanner pen head and a twist switch as claimed in claim 1, wherein, the upper end of the light emission device is made in conic to define a scanner pen point, also functioning as a flashlight when conducted by contacting the cells.

8. A pen with a scanner pen head and a twist switch as claimed in claim 1, wherein, two pins are provided to the lower end of the light emission device with one pin being folded to extend to the other side to contact the L-shape conductor while the other pin being vertical;

and the light emission device being adapted in the upper end of the upper pen holder to contact the upper side of the cells.
