The light transmission plate has first and second side surfaces, and an outer reflective layer coated on the second side surface. A portion of light rays emitted from the light-emitting component and into the light transmission plate pass through the outer reflective layer, and the remainder of the light rays are reflected by the outer reflective layer.

Abstract: A key device for a keyboard includes a circuit board, a keycap located over the circuit board, a supporting plate disposed under the circuit board, a first stabilizing member, a second stabilizing member and two supporting members. The supporting plate includes two first mounting seats cooperatively defining a rotating axis extending in a first direction. Each of the first stabilizing member and the second stabilizing member is made of a plastic material, slidably engages the keycap, and is rotatably mounted to the first mounting seats. When the keycap is pressed toward the supporting plate, the first stabilizing member and the second stabilizing member rotate relative to the supporting plate about the rotating axis.

Abstract: A thin keyboard apparatus includes a base plate and a supporting unit. The base plate has a plate body which is formed with four retaining openings and four retaining members. Each retaining opening is bordered by a peripheral edge which has first and second edge sections extending along two different and intersecting directions. Each retaining member has an upper wall, a first connecting wall interconnecting the upper wall and the first edge section, a second connecting wall interconnecting the upper wall and the second edge section, and a broken hole dividing the first edge section from the second edge section. The supporting unit is slidably pivoted to the retaining members.

Abstract: A touchpad press device includes a support unit having two first sides interconnecting between two second sides, and first engaging members proximate to the second sides. A touch unit with a touch switch is disposed above the support unit, and a transmission unit is disposed between the support unit and the touch unit. The transmission unit includes peripheral plates, each of which is disposed above one of the second sides and has second engaging members, and a pressing plate to trigger the touch switch. When one of the peripheral plates is pressed downward through the touch unit, the other peripheral plate turns upward so that the second engaging members thereof engage the respective first engaging members to limit the other peripheral plate from moving further upward.

Abstract: A pressing device includes a base board, an upper board unit that is disposed over the base board, and an intermediate unit that is disposed between the base board and the upper board unit. The upper board unit includes a panel, a circuit board, and a tact switch. The intermediate unit includes a middle portion that corresponds in position to the tact switch, a surrounding frame member, and a plurality of interconnecting board members. When the upper board unit is pressed, at least one of the interconnecting board members is deformed, and the middle portion is driven to convert the tact switch from an initial state to a triggered state.

Abstract: A pressing device for a touchpad includes a base unit, an upper board unit, and an intermediate unit. The upper board unit includes a trigger switch aligned with the abutment portion of the base unit. The intermediate unit has a surrounding frame member, two positioning members, two connecting members, and a actuating member that are interconnected by a plurality of linking ribs. When the upper board is pressed at a position above one of the surrounding frame member and the connecting members, one of the connecting members is moved relative to the actuating member by virtue of the linking ribs, and the actuating member provides a force to convert the trigger switch from an initial state to a triggered state.
