Abstract: The electronic device includes a first casing, a second casing, and a connecting member engaging with the first casing to allow the first casing to turn about a first axis of rotation, and engaging with the second casing to allow the second casing to turn about a second axis of rotation. When a turning angle is 0 or 360 degrees, a distance between the first and second axes of rotation equals to the sum of a half of the sum of the thicknesses of the first and second casings and a clearance between the first and second casings, and the first axis of rotation is arranged at a position shifted from the center of the first casing in a reference direction to the second casing side, by a half of a value calculated by subtracting the thickness of the first casing from the thickness of a first casing-side connecting portion.

Abstract: The mobile terminal device of the present invention includes at least one hinge and a first enclosure and second enclosure that are openably/closably connected by way of the hinge. The distances between the center of the hinge and the non-opposing surface of each of the first enclosure and second enclosure are equal. When the first and second enclosures in a closed state are rotated by the angle formed by the two normal lines drawn from the center of the hinge to the non-opposing surface of each of the first enclosure and second enclosure, the portions at which the non-opposing surfaces intersect the hinge-side side surfaces of the first enclosure and second enclosure match. The diameter of the hinge is equal to or less than the total length of the distances between the center of the hinge and the non-opposing surface of each of the first enclosure and second enclosure.

Abstract: A coupling device for coupling a first casing and a second casing in a movable manner, comprising a first coupling member provided at the first casing, a second coupling member provided at the second casing, and coupled to the first coupling member in such a way that the first casing and the second casing move relative to each other, and a cleaning mechanism that cleans a clearance between the first casing and the second casing or the second coupling member. The cleaning mechanism has a wiper blade that moves in the clearance with movement of the casings, air injection means that injects air to the clearance, and/or a hinge cover that is displaceable within the clearance.

Abstract: With a waterproof structure for the space between a first case and a diaphragm doubling as a display panel provided facing the first case, a first resilient member is integrally formed at a surface of the diaphragm facing the first case, and the first resilient member is press-fitted into a groove formed in a surface of the first case facing the diaphragm side.

Abstract: A waterproof structure for a casing has a first casing, a second casing to be put together with the first casing, and a waterproof member formed of an elastic material to prevent water from penetrating between the first casing and the second casing. The second casing has a recess. The waterproof member has a peripheral part which, when fitted into the recess, prevents penetration of water. The peripheral part is provided at the periphery of the waterproof member, which is laid out all around space between the first casing and the second casing. A projection engages with a dent. A restriction part of the first casing, provided at a position facing the peripheral part and protruding toward the second casing, prevents the peripheral part from coming out.

Abstract: A connector of the present invention comprises a jack socket with a plurality of first terminals disposed at a cylindrical inner wall at predetermined intervals in a depth direction, a plug with a plurality of second terminals disposed at an outer wall thereof, constituting a plurality of electrical contacts by individually making contact with each of the first terminals in a state of insertion into the jack socket, and ring-shaped elastic seal members that seal each of the electrical contacts when the plug is inserted in the jack socket.

Abstract: A first turning member is formed in a bottomed cylindrical shape. A pivot is convexly formed on the bottom of the first turning member, and a packing is wound around the first turning member. A boss is convexly formed on one surface of a second turning member, and a packing is wound around the boss. A pivot opening is formed in the other surface of the second turning member. The boss is inserted into the first turning member. The pivot is inserted into a ring-shaped waterproof member and a plain washer. The waterproof member surrounds the pivot opening. The waterproof member is sandwiched between the bottom of the first turning member and the end surface of the boss.
