PURPOSE:To prevent the breakdown of the IC and the wrong time of the watch and at the same time realizing the reduction of the number of component parts as well as a small size of the watch, by using the conductive component of the electronic circuit inside the case for the shielding means to the static electricity outside the case. CONSTITUTION:The voltage of battery 10 is applied to electronic circuit 6 and the razor motor via lead plate 9, coil spring 17 and pattern electrode 7 each. As a result, the motor turns to operate the razor's edge, and at the same time the watch elements within circuit 6 operate. And the voltage is applied to the electrode of upper glass 3 of the liquid crystal panel via rubber 16 to display the time. Parts 9a-9b of plate 9 encloses circuit 6, and circuit 6 uses the voltage of plate 9 for the earth potential. As a result, the static electricity generated in case 1 is discharged between case 1 and plate 9 to prevent the evil effect to circuit 6. |
