Abstract: A keyswitch structure includes a keycap having a vertical connection member and a vertical-horizontal-translation mechanism, a baseplate having a vertical connection member, a slidable part having a vertical-horizontal-translation mechanism, and a restoring member. The vertical connection members are engaged for constraining the keycap to move relative to the baseplate substantially along a Z axis. The vertical-horizontal-translation mechanisms are engaged, so that the slidable part can perform a motion in response to a movement of the keycap toward the baseplate along the Z axis upon a pressing operation. The motion includes a displacement in a first direction. When the pressing operation is discontinued, a horizontal restoring force by the restoring member enables the slidable part to perform a motion that includes a displacement in a second direction to move the keycap away from the baseplate along the Z axis. The second direction is opposite to the first direction.

Abstract: A holding apparatus engages with an information input device, particularly a foldable keyboard, for supporting portable electronic devices such as pocket PC, Palm PC, PDA, mobile phone and the like. The holding apparatus includes a receiving dock which has connector spindles pivotally engaged with the input device and a slot. A bracket is provided to slide in the slot at a first position to flatly fold on the input device to facilitate carrying when not in use. The bracket may be slid in the slot at a second position and be unfolded at a selected angle against the input device for the receiving dock to support the portable electronic device when in use.
