Patent ID: 7429039

Claim:
A hinge device for pivotably joining a main body of an equipment and one end of a movable member to enable the movable member to move between a face-down position and an upright position, the hinge device comprising: a fixed section that is fixed on the main body of the equipment; a support section that supports the movable member; a support-section-side pivot shaft that is disposed in the support section and extends along a direction orthogonal to a movement-locus plane where the movable member passes; and a fixed-section-side pivot shaft that is disposed in the fixed section and extends along the orthogonal direction, wherein the fixed section is provided with a fixed-section-side guide hole that engages with the support-section-side pivot shaft and guides the support-section-side pivot shaft in a direction departing from the main body as the movable member moves from the face-down position to the upright position, and wherein the support section is provided with a support-section-side guide hole that engages with the fixed-section-side pivot shaft at a position displaced toward one end of the movable member in relation to an engagement position between the support-section-side pivot shaft and the fixed-section-side guide hole, the support-section-side guide hole guiding the fixed-section-side pivot shaft to approach the support-section-side pivot shaft as the movable member moves from the face-down position to the upright position.
