<p><P>PROBLEM TO BE SOLVED: To provide a cord reel capable of easily adjusting decline of a power supply voltage at an output side end of a long cord. <P>SOLUTION: The cord reel 10 has a hollow cylindrical reel 11 whose both ends are sealed with left and right side plates 13 and 14 respectively. A left shaft part 17 of a shaft member is fixed to the left side plate 13, and a right shaft part 18 is fixed to the right side plate 14. A transformer 24 is supported by being held by fixing members 21 and 22 fixed to the inner ends of the left and right shaft parts 17 and 18. The right shaft part 18 which passes through the right side plate 14 is freely rotatably supported by a base. Since the left and right shaft parts 17 and 18 and the fixing members 21 and 22 are made of stainless steel which is a non-magnetic material, The space between the transformer 24 and the cylindrical reel 11 are magnetically interrupted, the transformer 24 is not affected by an external magnetic field, and power supply voltage drop by the cord 37 is appropriately corrected. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
