A two-axis hinge unit is provided with a first rotating shaft that rotates so as to open in the vertical direction from a folded state with a first casing and a second casing overlapping and a second rotating shaft that rotates so as to open in the horizontal direction from a folded state with the first casing and the second casing overlapping, and is provided with a restriction member positioned between the first rotating shaft and the second rotating shaft that, when one of the rotating shafts is in a predetermined rotational position, is pressed by this one rotating shaft and engages with the other rotating shaft, thereby restricting rotation of that other rotating shaft.

Two-axis hinge and mobile device

A hinge apparatus of the present invention comprises a first rotational shaft which rotates a first casing and a second casing relative to each other from a state where the first and second casings are folded down, and opens the first and second casings in a vertical direction, a second rotational shaft which rotates the first casing and the second casing relative to each other in a horizontal direction, a coupling member which couples the first rotational shaft and the second rotational shaft together, with an end portion of the first rotational shaft being overlapped with an end portion of the second rotational shaft, and an engagement member which allows either one rotational shaft of the first rotational shaft and the second rotational shaft to engage with the other rotational shaft, thereby restricting a rotation of the other rotational shaft when the one rotational shaft rotates.
