Abstract: A keyboard includes plural keys, a base plate and a backlight module. Each key includes a keycap and a sliding element. The keycap includes a first protrusion part. The sliding element includes a second protrusion part. The first protrusion part has a first slant surface. The second protrusion part has a second slant surface. The first slant surface and the second slant surface are in parallel with each other. When the keycap is depressed and moved toward the base plate, the first slant surface is moved along the second slant surface to push the sliding element to be moved relative to the base plate in a horizontal direction. Consequently, a light beam transmitted through the base plate is further transmitted through the sliding element and outputted from the keycap, or the light beam transmitted through the base plate is blocked by the sliding element.

Abstract: A key structure includes a base plate, a switch circuit board, a keycap, and an enclosure frame. The keycap includes a magnetic element. The magnetic element is disposed on an edge part of the keycap. The enclosure frame includes a magnetic coating layer. The magnetic coating layer is formed on an edge part of the enclosure frame and disposed over the magnetic element. When the keycap is depressed, the keycap is moved to trigger the switch circuit board, so that the switch circuit board generates a key signal. When the keycap is no longer depressed, the keycap is moved toward the magnetic coating layer in response to the magnetic force. The key structure can be normally operated without the need of installing an elastic rubbery element.

Abstract: A circuit layer manufacturing method is applied to a portable computer. The portable computer includes a front bezel, a display module, and a back cover. The front bezel is connected to the back cover for containing the display module. The front bezel includes a metal portion. The metal portion has a flat region corresponding to a side of the back cover. The circuit layer manufacturing method includes forming at least one control circuit layer assembly on the flat region, grounding the control circuit layer assembly to the flat region, and forming a protection layer on the control circuit layer assembly. The control circuit layer assembly includes an insulation layer and a control circuit layer. The control circuit layer is electrically connected to the display module. The insulation layer is formed between the control circuit layer and the flat region for being alternately stacked with the control circuit layer.
