Patent attributes
An information processing apparatus includes a first case and a second case. A connection assembly connects the first case to the second case such that the cases are rotatable about a shaft member disposed in the connection assembly. The connection assembly includes a first link member attached at one end to the first case and at another end to a second link member included in the second case, and a spring assembly attached at one end to the second link member and at another end to the second case. A torque is generated by the connection assembly relative to the shaft member in a direction corresponding to one or more of a closed state and an open state. The torque is generated in the direction corresponding to the closed state when respective front surfaces of the cases are separated by less than a predetermined polar angle.
