Abstract:
1. An electronic device, comprising: a first casing; a second casing having a display; a hinge mechanism having: the first recess is open on at least one of a front side and a rear side in the axial-component receiving section, and the second casing is rotated about the inverting axial-component relative to the first casing, and the axial-component is moved into or out of the recess through the side on which the first recess is open, the second recess is open only on the same side as a side on which the first recess of is open, among a front side and a rear side of the second recess, and the second casing is rotated about the inverting axial-component relative to the first casing, and the axial-component is moved into or out of the first recess through the side on which the recess is open, and in each of the first axial-component receiving section and the second axial-component receiving section, the other of the front side and the rear side of the first recess forms an axial-component stop wall that prevents passing of the axial-component; a projecting component that projects from a casing with the axial-component, among the first casing and the second casing, having the axial-component provided therein, that fits into the second recess in the normally opened position, and that fits into the first recess in the inversely opened position; and an elastic component used for changing an amount of projection of the projecting component from the casing with the axial-component, wherein the axial-component passes on the side on which the recess is open, and the projecting component is pushed by the axial-component stop wall according to a rotation of the second casing to contact the elastic component, and an amount of projection of the projecting component is thus reduced to allow the projecting component to pass by the axial-component stop wall, in the course of switching between the normally opened position and the inversely opened position.
