OPERATOR DEVICE FOR ELECTRONIC MUSICAL INSTRUMENT

摘要

A switch is constituted by a movable conductive portion and a pair of fixed conductive portions. The fixed conductive portions are arranged on a substrate, and are each constituted by at least one strip member. A first main conductive pattern and a second main conductive pattern are arranged on the substrate in correspondence with the fixed conductive portions. The movable conductive portion electrically shorts the pair of fixed conductive portions upon coming into contact with both of them. The strip members that constitute the fixed conductive portions each have a first end portion and a second end portion in the extending direction, and the end portions are electrically connected to the corresponding main conductive patterns.

1. An operator device for an electronic musical instrument, the operator device comprising:
a substrate; a first fixed conductive portion and a second fixed conductive portion that are arranged on the substrate and make up a pair of electrodes; a first main conductive pattern and a second main conductive pattern that are arranged on the substrate, have a higher conductivity than the first and second fixed conductive portions, and respectively correspond to the first fixed conductive portion and the second fixed conductive portion; and a movable conductive portion that is configured to move by an operation performed on the operator, and electrically shorts the first fixed conductive portion and the second fixed conductive portion upon coming into contact with both of them, wherein the first fixed conductive portion and the second fixed conductive portion are each constituted by at least one strip member, and the strip member constituting the first fixed conductive portion and the strip member constituting the second fixed conductive portion are aligned in parallel and in an alternating manner, and at least two end portions of the strip member constituting the first fixed conductive portion are electrically connected to the first main conductive pattern, and at least two end portions of the strip member constituting the second fixed conductive portion are electrically connected to the second main conductive pattern.
