Title:
MOVEMENT DETECTION DEVICE AND MOVEMENT DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/219736
Kind Code:
A1
Abstract:
[Problem] To prevent fraud in which a pair of members are moved from an origin position while applying another detected part so as to prevent the detection of the movement of the pair of members from the origin position. [Solution] In a movement detection device 10 according to the present disclosure, a first unit 11 has five magnetic sensors 13, whereas a second unit 30 has three permanent magnets 32. As a result, when a double sliding window 100 is fully closed and the first unit 11 and the second unit 30 face each other, three magnetic sensors 13 detect the permanent magnets 32 and outputs a detection signal whereas two magnetic sensors 13 do not detect the permanent magnets 32 and do not output a detection signal. A control unit 14 determines whether or not the double sliding window 100 is fully closed on the basis of the combination of the magnetic sensors 13 that are detecting the permanent magnets 32 and the magnetic sensors 13 that are not detecting the permanent magnets 32.
