An opening and closing unit which satisfies required functions of an opening and closing unit and is able to more smoothly bend/unfold a terminal, link parts are slidable with rotation relative to an attaching member. Link parts are slidable with rotation relative to an attaching member. Central parts are provided between the link members and the link parts, with one end portion thereof being slidable relative to the link members with rotation, and other end portion thereof being slidable relative to the link parts with rotation. The friction generating portions are provided between an attaching part and central parts, and apply a resistance force against a rotation of the central members relative to the attaching part. The friction generating portions are provided between an attaching part and central parts, and apply a resistance force against a rotation of the central parts relative to the attaching part.

Opening and closing device and terminal device

To provide an opening and closing device which can eliminate the torque fluctuations and ensure a secure unlocking, the opening and closing device based on biaxial hinge ensures that, when the second casing is opened from the close position to the initial opened position, and the stopper plate rotates relative to the first hinge shaft up to the initial opened position, the hinge shaft switcher switches from restraints to the rotation of the first hinge shaft to those to the rotation of the second hinge shaft, thus fixes the stopper plate at the initial opened position. The opening torque of the second casing is merely the sum of the torsion torque of the torsion spring and the friction torque of the first free stop tilting mechanism, and not subject to torque fluctuations. Therefore, the second casing can be securely opened.

A biaxial hinge has a first hinge portion which includes a first A hinge shaft, a second A hinge shaft, and a first radial direction coupling unit for coupling the first A hinge shaft and the second A hinge shaft. The biaxial hinge also has a second hinge portion which includes a first B hinge shaft and a second B hinge shaft, and a second radial direction coupling unit for coupling the first B hinge shaft and the second B hinge shaft. The biaxial hinge also has an axial direction coupling unit.

In order to provide a biaxial hinge and terminal device which ensure that a first and a second casings can open and close 360 degrees relative to each other, as well as enable a keyboard portion and rubber feet to sink relative to the upper surface of the first casing, from a predetermined opening/closing angle, the biaxial hinge comprises a biaxial hinge portion and an actuating mechanism for actuating operating mechanism(s) working on keyboard and rubber feet. Further, the actuating mechanism comprises a cam part moving in association with the movement of the biaxial hinge portion and together with opening/closing operations of the first and the second casings, and a slide part of which an end contacts with the cam part. The slide part is further provided on the attaching plate attached to the first and the second hinge shafts so as to start moving from a predetermined opening/closing angle.

To provide a biaxial hinge which enables an opening/closing movement of terminal, such as notebook PC, from 0&#xb0; up to 180&#xb0; or more, which ensures the opening/closing movement starting from a stable stopping position available at any opening/closing angle, a second hinge shaft attached to a second casing and a second hinge shaft attached to a second casing are connected to each other via a joint member and provided so as to be rotatable relative to each other, and a selective rotation restricting device is provided between the both hinge shafts. The selective rotation restricting device is so structured that it allows the both hinge shafts to rotate, when the first casing and the second casing are in a closed state, and it restricts one of the first hinge shaft and the second hinge shaft in rotation, when the other hinge shaft rotates relative to the one hinge shaft.

Biaxial hinge

A slide hinge for a small-sized information terminal having a first casing with keyboard and a relatively slid second casing with display. The slide hinge has a linear slide between the first and second casings, and a turning mechanism for a turning operation of the casings. The slide has a first guide groove provided on an undersurface of the second casing, a guide pin engaged with the first groove and attached to an upper surface of the first casing. The turning mechanism has a rotary hinge on an upper surface of one side of the first casing, a turning member rotatably attached to the rotary hinge in a horizontal direction, and a second pin attached to a free end of the turning member and engaged with a second groove provided on the undersurface of the second casing in cross direction of the first guide groove.

Slide hinge for small-sized information terminal

A slide hinge is provided for a small-sized information terminal composed of a first casing and a second casing. The slide hinge functions to relatively and automatically slide the first casing and the second casing from predetermined slide positions. The slide hinge is provided between a first casing provided with a keyboard portion and a second casing provided with a display portion so that the two casings are relatively slid. The slide hinge includes a linear slide assembly provided between the first casing and the second casing and a turning assembly being configured to generate rotation torque from a predetermined turning angle so that the first casing and the second casing automatically and relatively slide in an opening direction and/or a closing direction depending on the slide position thereof.

A hinge device comprises: an attachment member attached on an apparatus body side; a supporting member pivotally supported by the attachment member through hinge pins; a document press-contacting plate attached to the supporting member; compression springs elastically provided between the supporting member side and the attachment member in such a manner that the supporting member is enforced to pivot in a direction that the document press-contacting plate is opened; a damper set inside the compression springs and provided between the attachment member side and the free end side of the supporting member so that an abrupt pivoting at and from a predetermined angle measured from the supporting member is buffered. This hinge device allows an adjustment of the elastic force of the compression springs without changing the operation angle of the damper, by attaching an adjustment plate on the damper movably in an axial direction, and by elastically providing the compression springs between the adjustment plate and either of the supporting member side or the attachment member side.
