<P>PROBLEM TO BE SOLVED: To provide a power consumption state display device capable of easily measuring and monitoring electric energy of the whole house. <P>SOLUTION: Power consumption is monitored by using a power consumption state display device 4 having a light-emitting display part 12 on which the speed of simulated rotation or simulated flow changes in response to power consumption through taking out a current variation of a power supply as a voltage variation by using a current measurement circuit, performing pulse conversion by using an A/D conversion circuit, and making each of multiple light-emitting bodies 11 sequentially flash by using a microcomputer, so that anybody can visually recognize an instantaneous power consumption state at an optional indoor spot in each business office or in each house at anytime. <P>COPYRIGHT: (C)2013,JPO&INPIT |
