Abstract
The invention can increase the induced voltage by arranging two adjacent frequency generating coils serially, and also suppress the variation of the induced voltage by omitting the teeth pattern of the frequency generating coils at the opposite position of the section where the coil pattern is not provided due to the driving circuit elements. In addition, the driving circuit elements are mounted on both inner and outer sides of the coil pattern on a single PCB and the expensive dual pattern PCB or any additional PCB is not required, so that the manufacturing cost is reduced and the assembling process becomes easier.
