One end portion of a connecting memberis connected to a first housingsuch that the connecting memberis rotatable about a first rotation axis L. The other end portion of the connecting memberis connected to a second housingsuch that the connecting memberis rotatable about a second rotation axis Lparallel to the first rotation axis L. The first and the second housingsare arranged such that when the second housingis rotated up to a predetermined intermediate position, opposite end portions of the first housingin a direction perpendicular to the first and the second rotation axes L, Lare protruded from the second housingin the said direction.

Portable device

One end portion of a connecting memberis connected to a first housingsuch that the connecting memberis rotatable about a first rotation axis Lfixed in position with respect to the first housing. The other end portion of the connecting memberis connected to a second housingsuch that the connecting memberis rotatable about a second rotation axis Lfixed in position with respect to the second housingand extending parallel to the first rotation axis L. The first housingand the second housingare located in different locations in a direction of the first and the second rotation axes L, Lsuch that a top surfaceof the first housingand an undersurfaceof the second housingare located generally on a same plane.

Portable device and hinge assembly

A hinge assembly comprising a movable memberand a fixed memberrotatably connected to each other and a coiled spring (not shown) biasing the movable membertoward the fixed member. A receiving recessis formed in an opposing surfaceof the movable memberfacing the fixed member. A spherical bodyis received in the receiving recesssuch that the spherical bodyis movable in a circumferential direction of the movable member. A first cam portionis formed in an opposing surface of the fixed memberfacing the movable member. Rotation of the movable memberin a direction of an arrow causes the cam portionto be abutted against the spherical body. The cam portionconverts a biasing force of the coiled spring into a rotational biasing force. The rotational biasing force causes the spherical bodyto be rapidly abutted against a first hitting portionof the receiving recessand thereby to generate a clicking sound.
