A control housing is provided which encases a control board. The housing has a cover and a backing which are fixed together to secure the control board within the housing. The control board includes a plurality of switches, and the housing includes a plurality of corresponding buttons to activate the switches. The cover includes a cover surface having at least one button hole in register with the control board switch; operating insignia integrally formed on the cover surface adjacent the button hole; and a membrane which closes said button hole to form a button surface. The insignia is exposed through the membrane to be exposed and visible. The membrane is fused to the cover, thereby providing a housing which is sealed to substantially prevent gases, liquids or solids from entering the housing.

A key mechanism for actuating a circuit board includes a housing whereon an opening is formed, a key button installed inside the opening of the housing, and a waterproof structure installed between the key button and the circuit board for preventing fluid from leaking into the circuit board via an interface of the housing and the key button. A space is formed between the waterproof structure and the key button for containing the fluid leaking from the interface of the housing and the key button. The space is lower than the interface of the housing and the key button.

A sealed dome switch assembly is provided to allow air to flow between the interior and the exterior of the dome switch during the collapse and recovery of the resilient dome shell. The sealed dome switch assembly comprises at least one vent leading between the interior space and the exterior space of the sealed dome switch, wherein the vent is covered by a membrane that is permeable to air and resilient to liquid (e.g. water) and small particles (e.g. dirt). A vent may also be used to network the interiors of a plurality of sealed dome switches to at least one exterior entranceway that is covered by the membrane.

A button assembly applied on an electronic device is provided. An electronic device includes a housing and a button assembly. The housing defines two through holes and includes a first latching member. The button assembly includes a button body and a sealing frame. The button body includes two keycaps and a waterproof layer. Each of the keycaps extends through one of the through holes and is external to the housing. The waterproof layer is made of elastic waterproof material. The sealing frame includes a second latching member and is fixed to the housing. The waterproof layer corresponding to the first latching member and the second latching member is deformed, which creates waterproof seal.

A transmissive key sheet using translucent resin, which is capable of effective illumination while ensuring the thinness of the entire key sheet as well as suppressing a decrease in light transmission, input keys using the transmissive key sheet, and electronic equipment with the input keys. A transmissive key sheet of input keys comprises a first key sheet unit and a second key sheet unit, the opposite side of the first key sheet unit from key tops and the opposite side of the second key sheet unit from pressure applicators being bonded together with a translucent adhesive. The key tops made of translucent resin are molded integral with a translucent resin film having letters on its under surface to provide the first key sheet unit. The pressure applicators made of translucent resin are molded integral with a translucent resin film to provide the second key sheet unit. The light from a light source on a substrate illuminates keys so that the letters printed on the under surface of the translucent resin film become visible form outside. The pressing of each key top presses a corresponding key switch through the pressure applicator, and the key switch is concavely curved to make a contact with an electrode on the substrate. Thus, key input is provided.

A keyboard comprising a plurality of transparent keys. In use, the keyboard is attached to a device such as a mobile device, to overlie a display screen of the device. One or more images displayed on the display screen are made visible to a user through the keys, which may be pressed by a user. User input is determined by identifying a pressed key, and the image or part thereof visible through the key when pressed.

An object of the present invention is to provide a keyboard input device that has a key arrangement similar as an ordinary keyboard, and that can securely protects key tops when folding. The present invention is characterized as follows. A keyboard unit is divided into a first keyboard unit and a second keyboard unit so as to be foldable, the first keyboard unit is pivotably supported by the second keyboard unit so as to pivot about a position slightly inside from an end of a coupling side of the second keyboard unit, a cover for covering an area from the end of the coupling side of the second keyboard unit when the first keyboard unit and the second keyboard unit are superimposed is slidably attached to the first keyboard unit, and an end plate for covering the end of the coupling side of the second keyboard unit and the first keyboard unit when the first keyboard unit and the second keyboard unit are superimposed is pivotably coupled between the cover and the second keyboard unit.

Apparatus for detecting the opening and closing angle which is easy to switch, is reliable, is capable of positively preventing howling from occurring, can be reduced in size and weight, and uses no special components. The apparatus comprises a first and second hinge portions belonging to a first and second housings, respectively, for pivotal linking said first housing to said second housing. The first hinge portion has on the lateral side a curved surface in a rotational direction of said first housing and comprises a given number of parallel electrodes extending in a rotational direction of said first housing on said convex curved surface. The curved surface portion is disposed in the second housing; the second housing includes therein terminals in pressure contact with said electrodes or the curved surface; the terminals are in contact or non-contact with corresponding electrodes at different predetermined angles depending on the rotation of the first housing.

A waterproof structure with a simple structure and a good assemble workability is provided. A recess portion is formed on a side of an inner casing, and a through hole is formed at the bottom of the recess portion. The through hole runs to a housing recess portion, and a dome switch opposes to the through hole in the inner casing. A protrusion of a cup member is inserted into the through hole from the outside of the inner casing. A protrusive portion protruding from the bottom surface of a push button is inserted into the opening of the cup member. A rubber sheet which couples the push button is sandwiched between the inner casing and a top cover and a back cover.

A switch unit is provided, which includes: an operative body being swingingly operably provided; a pair of first switch portions being abuttable on respective end portions of the operative body when the operative body is swingingly operated so as to output signals to raise and lower, respectively, a window glass; a pair of second switch portions arranged apart from a line connecting the pair of first switch portions and nearer a longitudinal middle portion of the operative body than the first switch portions and being abuttable on the operative body when the operative body is swingingly operated so as to output signals to raise and lower, respectively, the window glass; and a pair of supporting portions arranged opposite to the pair of second switch portions with respect to the line, wherein the supporting portions abut on respective portions of the operative body when the first switch portions abut on the respective end portions of the operative body.

A wearable computing, input, and display device is disclosed. One embodiment of the invention includes a band wrappable around a wrist of a user, one or more input mechanisms, a display mechanism, and a computing mechanism. The input mechanisms are attached to the band and have recessed and extended positions. In the recessed position, the input mechanisms are positioned under the wrist of the user. In the extended position, the input mechanisms are substantially positioned at the user's fingertips. The display mechanism is attached to the band such that it is over the wrist of the user, whereas the computing mechanism is attached to the band and operably coupled to the input and display mechanisms. In an alternate embodiment, the display mechanism is additionally rotatable from a flat position to a raised position, and vice-versa, where the raised position is user controlled for optimal viewing by the user.
