Abstract
PURPOSE: To detect locking with a single sensor and simplify installation and wiring by attaching an inner force sense resistor that changes its resistance value in accordance with load to a fixing portion that receives the load of a moving portion such as a sliding door or the like that is caused by locking. CONSTITUTION: An inner force sense resistor 10 formed of a flexible, durable, very thin pressure sensitive film that is formed on a polymer face by screen printing is attached to a sash fixing portion 12 which a sash moving portion 11 contacts when closed, so that it may sense load occurring solely when locking is effected when the moving portion 11 is closed. Locking is detected by detecting the resistance value variation characteristics in accordance with the state of the sash through leads 13 and 13 led out from the inner force sense resistor 10 and discriminating clearly the open state or closed state from locking by a sudden decline in resistance value during locking.
