Estimating the term…

Abstract

A ball pen includes an electronic watch embedded in an inner jacket fixed within a pen cap, wherein the pen cap may be depressed to push ball point outwards for writing use and at the same time, electrically contact a circuit of the electronic watch for shifting the normal operation such as hour and minute indication to another operation such as month-and-date indication.

Claims2

Dependent claims

A ball pen combined with electronic watch comprising:

a hollow pen cap, an inner jacket fixed within said pen cap, an electronic watch embedded in said inner jacket, an outer spring backing the lower portion of said inner jacket, a resilient conductor formed with two resilient conducting plates each terminated with a hook and tensioned under said outer spring, a shifting stabilizer clamped by said resilient conductor and formed with several lengthy extensions therein, and formed with two holes for said hooks of said resilient conductor extending therethrough, a connector connected with the lower portion of said shifting stabilizer, a lower penholder fixed under said connector, an innermost spring positioned and tensioned under said electronic watch, a contacting bolt positioned under said innermost spring and formed on its lower portion with a setting wheel having a following gear, said setting wheel having contacting surfaces a driving rod inserted in the lower hollow portion of said inner jacket and formed with a driving gear on its lower portion to reciprocatively move within said shifting stabilizer and movably drive said following gear, an inner refill tube positioned under said setting wheel and a power cell fixed between said electronic watch and an uppermost cover by a spiral spring inserted under said uppermost cover;
the improvement which comprises:
an electronic watch having a printed circuit board, which is formed with a first contactor on the top end of said watch to contact one electrode of said power cell;
a second contactor formed as a resilient plate connected to said inner jacket to electrically contact said pen cap, said uppermost cover, said spiral spring and another electrode of power cell for normal time indication;
a third contactor extending from said printed circuit board to an end slightly separated from a resilient plate formed on said inner jacket and being internally connected to a re-set pin of an integrated circuit of said printed circuit board;
and a fourth contactor positioned under said electronic watch to electrically contact said innermost spring, whereby, when depressing said pen cap to lower said driving rod, said driving gear will force said following gear along the length extensions formed in said shifting stabilizer to be held at the lowest end of said lengthy extensions to extend said inner refill tube with ball point for writing use and at the same time, the hooks of said resilient conductor extending through the holes of said shifting stabilizer electrically contact the contacting surfaces of said setting wheel, said contacting bolt, said innermost spring and said fourth contactor of printed circuit board to close an electric circuit through said first contactor, said power cell, said spiral spring, said uppermost cover, said pen cap, said inner jacket, said outer spring, said resilient conductor so as to shift the normal operation of said electronic watch to another operation.
