The present disclosure provides an input device including a housing, a keyboard assembly, and a first light source. The housing comprises a body and a plurality of sidewalls. The plurality of sidewalls is disposed along the body, forming an accommodating space. The keyboard assembly is disposed in the accommodating space. The first light source is disposed in the body. The light emitted from the first light source emits from the plurality of sidewalls, creating a glowing effect on the periphery of the keyboard assembly. By configuring computer using modes corresponding to the light emitting states, it is possible for users to intuitively discriminate the using patterns.

A keyboard backlight module includes a light guide plate, a reflector, a light-emitting device and a first microstructure. The light guide plate has an output surface, a light guide pattern and a bottom surface disposed on an opposite side of the output surface. The light guide pattern is arranged on at least one of the bottom surface and the output surface. The reflector has a reflecting surface facing the bottom surface. The light-emitting device is disposed on one side of the light guide plate and configured to provide an incident light to the reflecting surface. The first microstructure is disposed on the reflecting surface, at least partially overlaps with the light guide pattern, and is configured to transform the incident light into a first reflected light.

A key structure, including a keycap, a scissor component, an elastomer, an optical switch, a shading portion, and a circuit board, is provided. The scissor component is formed of a first and a second supporter. The circuit board has two first and two second limiting units. The keycap has two third and two fourth limiting units. The first supporter is rotatably or slidably connected to the first and the third limiting units. The second supporter is rotatably or slidably connected to the second and the fourth limiting units. The keycap is disposed on the circuit board through the scissor component. The elastomer is interposed between the circuit board and the keycap. The optical switch includes an emitter and a receiver. The shading portion is disposed on the first or the second supporter to block a light signal transmitted between the emitter and the receiver.

A key structure includes a keycap, a connection assembly, engaging members, and a base plate. The connection assembly disposed between the base plate and the keycap is movably connected to the keycap and the engaging members, so that the keycap and the connection assembly engaged with the engaging members are positioned on the base plate. The base plate includes engaging protrusions protruding from an upper surface, so that the engaging members are bonded to the base plate through the engaging protrusions. Each engaging protrusion is located between two openings of the base plate, connects the two openings, or is disposed corresponding to the openings. Each engaging member covers one or more engaging protrusions through injection molding, and is fixed to the base plate. The engaging members are respectively disposed on the openings, fill the openings, or completely cover the engaging protrusions.

A key structure and a keyboard using the same are disclosed. The key structure includes a bottom plate, a keycap, a lifting mechanism, a backlight module, a fixer and a fixing portion. The lifting mechanism pivotally connects the bottom plate and the keycap. The backlight module is disposed on the bottom plate and is provided with a through hole, a first surface and a second surface opposite to the first surface. The through hole is extended to the second surface from the first surface. The fixer presses the first surface. The fixing portion presses the fixer on the bottom plate.

A membrane keyboard structure and a conductive method thereof allows a first surrounding portion of a first flexible circuit layer to be deformed to pass through an through hole to be in direct contact and conduction with a second surrounding portion temporarily when it is pressed through the coordination of a first flexible sheet body, first flexible circuit layer configured on the first flexible sheet body, spacer layer positioned on one side of the first flexible sheet body adjacent to the first flexible circuit layer, second flexible sheet body configured on one side of the spacer away from the first flexible circuit layer and second flexible circuit layer configured on one side of the second flexible sheet body adjacent to the spacer layer. Whereby, the present invention can achieve the contact and conduction anywhere to make the use thereof easier and more convenient.

A key structure includes a movable element, an elastic element, a light-emitting element and a pressure sensing element. The pressure sensing element is arranged between the elastic element and the light-emitting element. The elastic element is disposed on the movable element. The light-emitting element emits a light beam. The light beam is transmitted through the pressure sensing element and projected to the movable element to illuminate the key structure. While the key structure is depressed, the elastic element is pushed by the movable element. The pressure sensing element is pushed by the elastic element according to different magnitudes of the depressing force. Consequently, the key structure generates different pressure sensing signals.

A multicolor illumination keyboard includes a light-emitting element, a color filter and plural keys. The plural keys are located above the light-emitting element. The color filter is arranged between the plural keys and the light-emitting element. After a source light emitted by the light-emitting element passes through the color filter, plural color lights are generated. The plural color lights are outputted from the plural keys. Consequently, the plural keys are illuminated in a multicolor manner.
