PARALLEL DOUBLE-SHAFT HINGE, AND MINIATURE ELECTRONIC DEVICE POSSESSING SAME

摘要

PROBLEM TO BE SOLVED: To provide a parallel double-shaft hinge capable of synchronously rotating a first hinge shaft and a second hinge shaft without using a gear, and eliminating restriction on design of a miniature electronic device without causing looseness.;SOLUTION: This parallel double-shaft hinge includes: a bridging element installed in a connecting element; the first hinge shaft and the second hinge shaft installed in a parallel state so as to be rotatable to the bridging element and movable in the mutually separating direction, the first hinge shaft rotatably supporting any one of a first shell and a second shell, and the second hinge shaft rotatably supporting any other; a synchronous rotation communication means constituted of a first link means and a second link means arranged by interposing the bridging element between the first hinge shaft and the second hinge shaft; and an inter-axial distance adjusting means for adjusting an inter-axial distance between the first hinge shaft and the second hinge shaft in response to opening-closing operation of the first shell and the second shell by interlocking with the synchronous rotation communication means.;COPYRIGHT: (C)2013,JPO&INPIT
