ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to a pen, and more particularly to a dual-purpose pen which can be used as a general ballpoint pen for writing or a pen to press keys on a notebook computer or the like.
2. Description of Related Art
A pen is used to press keys on a notebook computer, electric calculator or the like, which are too small to be individually pressed by a user's finger. A conventional pen to press keys is unable to be used for writing. If the user wants to write something, he or she must look for an instrument for writing.
Therefore, an objective of the present invention is to provide a dual-purpose pen to mitigate and/or obviate the aforementioned problem.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide a dual-purpose pen which can be used for writing or pressing small keys on a notebook computer or the like.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
