Title:
DEVICE FOR DETERMINING POSITION OF MOBILE STRUCTURE
Document Type and Number:
Japanese Patent JP2709871
Kind Code:
B2
Abstract:
PURPOSE: To make it possible to determine an absolute position of a mobile structure along a track by providing an electric switching means, an actuator means and circuit means and making the circuit means give a voltage signal having a magnitude proportional to a distance between an end part of a resistance means and a switching means.
CONSTITUTION: A sash position detecting means comprising a switching system 80 is provided adjacently to a sash door, and an actuator 94 is supported on the sash door and preferably is urged by a spring. When the sash door is moved, the actuator 94 is moved along the switching system 80 and a contact point between a resistance layer 84 and a conductor layer 88 is formed and is detected by a single electric circuit. A voltage proportional to a distance between a connection end of the resistance layer 84 and the contact point by the actuator 94 provided on another sash door in a track is generated. By this method, installation becomes easy, signals are generated by using a minimal number of parts and an excellent contribution to cost efficiency improvement in manufacturing phase can be realized.
