Electronic apparatus and hinge device

An electronic apparatus comprising:

• a first chassis;
• a second chassis adjacent to the first chassis;
• a first display provided on an upper surface of the first chassis;
• a second display provided on an upper surface of the second chassis;
• and
• a hinge device that connects the first chassis and the second chassis so as to be relatively rotatable at least from a folded form in which the first chassis and the second chassis are laminated to overlap in a surface normal direction to a flat plate form in which the first chassis and the second chassis are arranged in a direction perpendicular to the surface normal direction,
• wherein the hinge device comprises:
• a first bracket comprising a first fixing plate fixed to the first chassis;
• a second bracket comprising a second fixing plate fixed to the second chassis;
• a first hinge block that supports a first upper hinge shaft and a first lower hinge shaft arranged vertically between adjacent end surfaces of the first chassis and the second chassis in the flat plate form;
• and
• a second hinge block that is arranged side by side with the first hinge block in an axial direction of the first upper hinge shaft and the first lower hinge shaft, and supports a second upper hinge shaft and a second lower hinge shaft arranged vertically between the adjacent end surfaces in the flat plate form,
• wherein in the flat plate form, the first upper hinge shaft and the second upper hinge shaft are coaxial,
• wherein in the flat plate form, the first lower hinge shaft and the second lower hinge shaft are coaxial,
• wherein the first bracket further comprises:
• a first lower arm connected to the first lower hinge shaft to be connected rotatably relative to the first hinge block;
• and
• a first upper arm connected to the second upper hinge shaft to be connected rotatably relative to the second hinge block, and
• wherein the second bracket further comprises:
• a second upper arm connected to the first upper hinge shaft to be connected rotatably relative to the first hinge block;
• and
• a second lower arm connected to the second lower hinge shaft to be connected rotatably relative to the second hinge block.
