PROBLEM TO BE SOLVED: To provide a double-shaft hinge capable of opening or closing bit-by-bit the first casing and the second casing of terminal equipment alternatively over a range from 0 degree to 360 degrees under regularity and capable of holding them under a stable stopped state under an optional opening or closing angle. ! SOLUTION: A first hinge shaft 10 fixed to the first casing side and a second hinge shaft 12 fixed to the second casing side are connected in parallel to each other at least by a first connecting member 14 and a second connecting member 37 and rotatably arranged to each other, both first selective rotation regulation means 22 and second selective rotation regulation means 23 for selectively rotating the first hinge shaft 10 and the second hinge shaft 12 are arranged between the first hinge shaft 10 and the second hinge shaft 12, the first casing and the second casing can be opened or closed alternatively in order by these first selective rotation regulation means 22 and second sele |
