<p><P>PROBLEM TO BE SOLVED: To provide a light emission control system capable of making a light emitting part of a slave unit emit light even if the slave unit like a portable light emitting device is moved from a prescribed position set by a control device. <P>SOLUTION: The light emission control system is composed of a control device 12, a master device 14 connected to the control device 12, having a loop antenna 16, and a plurality of slave units 22(1) to 22(n) having a slave unit antenna 18 and light emitting part 20(1) to 20(n) respectively communicating with the master device 14 through the magnetic flux 30 emitted from the loop antenna 16. When a light emission treating command generated at the control device 12 is transmitted to the slave units 22(1) to 22(n) through the loop antenna 16 and the magnetic flux 30, respective slave units 22(1) to 22(n) located within a service area of the loop antenna 16 makes the light emitting part 20(1) to 20(n) emit light depending on the light emission treating command. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
