Automatic turn signal cancelling apparatus
First Claim
1. An automatic turn signal cancelling apparatus for a motorized cycle, comprising:
- a turning angle detector for detecting an handlebar turning angle when the motorized cycle makes a turn;
a distance detector for detecting a travel distance and producing a pulse output;
means, operatively connected with said turning angle detector and said distance detector, for accumulating the output of said turning angle detector in synchronism with the output pulse from said distance detector; and
logical arithmetic means, operatively connected with said turning angle detector and said accumulation means, for deciding upon cancellation of a turn signal on the basis of a combination of an output signal from said turning angle detector and that from said accumulation means.

Abstract
An automatic turn signal cancelling apparatus for a motorized cycle, in which a signal provided from a handlebar turning angle detector is accumulated in response to a signal provided from a travel distance detector, and the cancellation of turn signal is made on the basis of comparisons of such accumulated value and the output of the turning angle detector with respective preset values, whereby a more appropriate function of cancellation of turn signal can be achieved.
Further, by providing with a device for determining a turning angle center in accordance with signals from the turning angle detector and the travel distance detector, a more accurate function of cancellation of turn signal can be attained.
Moreover, an easier and more reliable operation is assured by providing a compact and functional operating switch assembly.
