A keyboard (110) comprises a base board (116), keys (112), pitfalls (120) and a mode control mechanism (118). The keys (112) include cups (1124), and the mode control mechanism (118) may switch the keyboard (110) especially the key cups (1124) between different modes. In case that the keyboard (110) is not in use, these cups (1124) can be received in the pitfalls (120) to reduce the profile of the keyboard (110). In case that the keyboard (110) is to be used, the keys (112) may be raised up and arranged on the base board (116) in order to enable long keystroke and provide good typing experience.

An electronic device case is shown and described. The device has a protective base member and a protective flap member. The protective base member has an exterior base surface and an interior base surface with a recess disposed in the interior base surface. The recess removably receives an electronic device. The protective flap member has an exterior flap surface and an interior flap surface. A display screen and at least one speaker are disposed in the interior flap surface of the protective flap member. The protective flap member is pivotally affixed to the protective base member and the protective base member and the protective flap member selectively move between an open and a closed orientation. The closed orientation is defined by the interior flap surface of the protective flap member resting against the interior base surface of the protective base member.

A keycap detachably provided on a guide mechanism of a key switch includes a cap main body having a front face pressed at the time of key input and a rear face on the opposite side to the front face; and a first engaging projection and a second engaging projection, both of which protrude from the rear face of the cap main body with a gap therebetween so that an engaging portion of the guide mechanism is detachably engaged into the gap. At least a part of an area around the first engaging projection and the second engaging projection in the cap main body has a thin part thinner than other parts of the cap main body. As a result, the falling off of the keycap can be prevented.

A portable device (e.g., a wireless device such as a cell phone) is provided with a flexible keyboard and a flexible display screen. Such flexible components may be stored in the housing of the portable device when not in use. The flexible display screen and flexible keyboard may be expanded from the housing when the flexible components are utilized by a user. Non-flexible display and input components may be provided on the exterior of the portable device such that the device may be used, in some form, while the flexible components are stored. In one embodiment, a portion of the flexible display (or flexible keyboard) may be utilized when the flexible display (or flexible keyboard) is stored in said first housing.

An electronic device including a body, an input module, and an engaging mechanism is provided. The input module is movably disposed at the body and adapted to move along an axial direction. The engaging mechanism includes a first engaging portion and a second engaging portion. The first engaging portion is connected to the input module. The second engaging portion is movably connected to the body and is adapted to move with a traction of gravity. When the axial direction has a first angle with respect to a direction of gravity, the second engaging portion is away from the first engaging portion so that the input module is adapted to move along the axial direction. When the axial direction has a second angle with respect to the direction of gravity, the second engaging portion is engaged with the first engaging portion to limit the movement of the input module in the axial direction, and the first angle is greater than the second angle.

A keyboard assembly is provided. The keyboard assembly includes an enclosure for protecting the keyboard and other components associated therewith. The enclosure is configured to engage with one or more bracket or bracket assembly, thereby providing a mounting system for supporting the enclosure. By engaging the enclosure with the bracket, the position of the keyboard can be controlled and maintained. By disengaging the enclosure from the bracket, the bracket can be moved and/or the enclosure can be engaged with a different bracket, thereby satisfying different requirements and/or preferences associated with the location of the keyboard.

A rollable and flexible input device includes a drum, a reel received in the drum, an input device body connected to the reel, and a battery. The reel is rotated relative to the drum so that the input device body is in a rolled-up state or a stretched state. The reel defines a battery cavity, and the battery is disposed in the battery cavity.

A mobile, versatile, transparent, double-sided data input device is described. The data input device includes a programmable, virtual keyboard with ergonomic benefits. The data input device includes a double-sided transparent touchscreen which provides keyed input and/or trackpad input to a separate computing device such as a mainframe computer, desktop computer, laptop, tablet, netbook, notebook, personal digital assistant (PDA), gaming console, e-reader, smartphone, or smartwatch by way of a wired or wireless connection, and includes control devices, such as a remote controller for gaming and/or control of one or more vehicles.

According to one embodiment, a keyboard PC includes a processor, a foldable keyboard, a housing, and an output terminal. The foldable keyboard comprises a first keyboard part and a second keyboard part. The housing that encloses the processor comprises a first housing part and a second housing part. The first housing part comprises the first keyboard part. The second housing part comprises the second keyboard part. The first housing part and the second housing part are configured to be opened or closed relative to one another by folding the housing. The output terminal supplies an image signal output from the processor to a display device.

An electronic device including a body, an input module, and an engaging mechanism is provided. The input module is movably disposed at the body and adapted to move along an axial direction. The engaging mechanism includes a first engaging portion and a second engaging portion. The first engaging portion is connected to the input module. The second engaging portion is movably connected to the body. When the axial direction has a first angle with respect to a direction of gravity, the second engaging portion is away from the first engaging portion so that the input module is adapted to move along the axial direction. When the axial direction has a second angle with respect to the direction of gravity, the second engaging portion is engaged with the first engaging portion to limit the movement of the input module in the axial direction, and the first angle is greater than the second angle.
