Title:
POWER GENERATOR
Document Type and Number:
Japanese Patent JP2015130731
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power generator used for various kinds of electronic apparatuses and operating devices etc. for remote-operating, which have a magnetic circuit constitution capable of reducing the size.SOLUTION: The power generator has a magnetic circuit constitution includes: a first member 71 having a U-like shape including a first permanent magnet 75, which allows a magnetic flux to flow; and a second member 82 having a U-like shape including a second permanent magnet 85, which allows a magnetic flux to flow, which are disposed at the front position and at the rear position relative to a center yoke 40 with a coil 60. The magnetic circuit constitution also includes: a third member 93 disposed at the outer left position, which allows a magnetic flux to flow; and a fourth member 94 disposed at the outer right position, which allows a magnetic flux to flow. With this, the power generator can be shaped to be thinner in a slide direction in which an electromotive force is obtained from the coil 60 according to a slide movement of the first member 71 and the second member 82 in a right and left direction.
