Title:
POWER GENERATION METHOD AND DOOR OPENING/CLOSING NOTICE APPARATUS USING THE SAME
Document Type and Number:
Japanese Patent JP2015126654
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power generation method which generates an induction current in a coil by using reciprocating-motion of external energy and a device which lights up with the electric energy.SOLUTION: A door opening/closing notice apparatus 40 can sense opening/closing of a door 1 in advance by attaching to the door 1 to operate a device which forms a movement part by attaching an elastic object such as a tension spring to a magnet for generating an induction current to a coil, forms a stationary part by fixing a magnet or the like for giving suction force to the magnet of the movement part, moves the tension spring or the like so as to separate the magnet of the movement part getting close due to the suction force from the magnet of the stationary part, and acquires instantaneous electricity flowing in the coil by immediately moving the magnet of the movement part at the moment when contractive force of the tension spring or the like exceeds the suction force of both magnets, or acquires electricity by immediately moving the magnet of the movement part with the suction force of both magnets by making both magnets close to each other and a light emission diode 3 or the like which lights up with the electricity.
