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.
