Claims
- 1. An electronic watch with a calculation function comprising:
- (a) a timepiece circuit having a reference oscillation source, a frequency divider and a time display driving circuit;
- (b) a computation circuit for performing the calculation function having a computation display driving circuit;
- (c) a display device connected to said time display driving circuit and said computation display driving circuit for displaying a time and a calculation solution;
- (d) an external operating member controlling said timepiece circuit and said computation circuit;
- (e) an outer casing comprising a case and a band;
- (f) an integral flexible hinge connecting said case and said band such that said case is integral with said band;
- (g) a conductive patterned film sheet integrally located within said flexible hinge, said case and the band;
- (h) a power supply source supplying energy through said conductive patterned film sheet to said timepiece circuit and said computation circuit; and
- (i) the electronic watch wherein said flexible hinge, said band and said case are comprised of an integral portion of a high molecular weight polymer which has a narrow region located between said case and said band which flexes and functions as said flexible hinge.
- 2. The electronic watch as claimed in claim 1 wherein further said band is provided with operation keys delivering a timepiece signal and a computation signal.
- 3. The electronic watch as claimed in claim 2 wherein said conductive patterned film sheet electrically connects said display device and said operation keys.
- 4. The electronic watch as claimed in claims 1 or 3 wherein the high molecular weight polymer is polypropylene.
