LIGHT PEN
First Claim
1. A light pen comprising:
- a case;
a light source disposed in the case for emitting light;
a pen-nib structure movably disposed through an end of the case, an opening being formed on the pen-nib structure;
a first lens device movably disposed between the light source and the pen-nib structure for guiding the light emitted by the light source to the opening;
an elastic piece connected to the first lens device for engaging with the pen-nib structure to fix a position of the pen-nib structure relative to the first lens device;
a hollow knob rotatably sheathing the first lens device; and
a linkage pipe sheathing a side of the first lens device and connected to the hollow knob, the linkage pipe being used for driving the elastic piece to move away from the pen-nib structure when the hollow knob rotates to a first position relative to the first lens device so that the pen-nib structure is capable of moving relative to the case and for being separate from the elastic piece when the hollow knob rotates to a second position so as to cause the elastic piece to engage with the pen-nib structure.

Abstract
A light pen includes a case, a light source, a pen-nib structure, a first lens device, an elastic piece, a hollow knob, and a linkage pipe. The pen-nib structure is disposed through the case. The first lens device is disposed between the light source and the pen-nib structure. The elastic piece is connected to the first lens device. The hollow knob rotatably sheathes the first lens device. The linkage pipe sheathes the first lens device and is connected to the hollow knob for driving the elastic piece to move away from the pen-nib structure when the hollow knob rotates to a first position, so that the pen-nib structure can move relative to the case. The linkage pipe is further used for being separate from the elastic piece when the hollow knob rotates to a second position, so that the elastic piece can be engaged with the pen-nib structure.
