Claims

[Scope of utility model registration request]

a movable member that includes a plurality of contact pieces and rotates in conjunction with the rotating shaft of the throttle valve; and a plurality of electrical patterns that move while the contact pieces are in sliding contact, one of the contact pieces. two signal patterns formed in a substantially comb shape in which the contactable protrusions and non-contactable concave portions are alternately provided at predetermined intervals, and the convex portions and the concave portions are out of phase with each other; a signal generator including at least a ground pattern, one of which can be contacted at all times;
The control means is provided with a control means into which signals output from each of the patterns are input, and the control means is provided with an ON signal that is output from one of the signal patterns in response to contact or non-contact of the contact piece with the convex portion of the pattern. - OFF signal and two types of pulse-like signals that are output in different forms depending on the change from contact to non-contact and from non-contact to contact of the contact piece from the other signal pattern to the convex part of the pattern is input, and the OFF
A throttle characterized in that a counter is provided that performs up and down counter operations according to the combination of the signal and two types of pulse signals, and the throttle position is detected based on the signal output from the counter. Position detection device.
