摘要

PURPOSE: A mat for game using a reed switch and magnetic core is provided to accurately detect input position through a physical locus. CONSTITUTION: A mat for game comprises: a board having a plurality of reed switchs; a sensor(10) with a magnetic core which opens and closes the reed switch; and a controller(20) which recognizes the position of reed switch and transfers position information to the executing device.
