PURPOSE:To always obtain a signal having pulse width of an equal interval, by constituting so that width of each electric conductor in the sliding direction of a comb-line electric conductor pattern is narrower than an interval of the electric conductors. CONSTITUTION:A contact state of a sliding brush and a comb-line pattern is shown in the figure. As shown in the figure, electric conductor width (a) of the comb-line pattern has been made narrower than its interval (b), therefore, an on- time and an off-time in case of sliding the brush becomes almost equal, by which it is possible to always obtain a signal having pulse width of an equal interval. |
