<p><P>PROBLEM TO BE SOLVED: To provide a cord reel capable of automatically adjusting the variation of an output voltage due to voltage drop or the like that occurs at the output side end of a long cord so as to be a target voltage. <P>SOLUTION: For the cord reel 10, a shaft member 19 passes through an axial center of a hollow cylindrical reel 11 whose both ends are sealed with left and right side plates 13 and 14, both ends of the shaft member 19 are freely rotatably supported by a base 23, and a stabilized power supply unit 40 is housed inside the cylindrical reel 11. The stabilized power supply unit 40 is attached to left and right attaching plates 16 and 17 made of stainless steel inside the cylindrical reel 11, and is disposed in the state of being magnetically interrupted from the outside, and the characteristic is appropriately demonstrated without being obstructed by an external magnetic field. Thus, the voltage drop or the like of an AC power source which has occurred at the end of the long cord is corrected by the stabilized power supply unit 40, and an appropriate output voltage suited to a predetermined target voltage value is supplied at all times. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
