A data input and/or operator control system, particularly a keypad, also a POS keypad, having a lower portion and an upper portion and also at least one printed circuit board and at least one retaining plate. Inside, one or more protective mat(s) made of an elastic material is/are preferably adhesively bonded to the printed circuit board. In this protective mat, the components of the printed circuit board are recessed to as small an extent as possible and air ducts are incorporated in order to ensure that the keys are ventilated in relation to one another.

The invention provides a touch device and an input module. The touch device includes a cover plate, a circuit board, a restoration element, a bracket, at least one conductive pad, and a buffer layer. The circuit board is disposed on one side of the cover plate and has a first surface facing the cover plate, a second surface opposite to the first surface, and at least one conductive switch disposed on the second surface. The bracket is disposed on the second surface of the circuit board. The restoration element is disposed on the second surface, and the conductive pad is disposed on the bracket and located between the bracket and the circuit board. The conductive pad and the restoration element are separately disposed, and the conductive pad corresponds to the conductive switch. The buffer layer is disposed between the second surface and the restoration element.

The invention provides a light guide structure, adapted to be disposed under a baseplate of a keyboard module. The light guide structure includes: a light guide plate, a mask layer and a reflective layer. The light guide plate includes a first surface, a second surface opposite to the first surface, and a first opening running through the first and second surfaces. The mask layer is located between the baseplate and the light guide plate, and includes a second opening corresponding to the first opening. The reflective layer includes a first part and a second part connected to each other, wherein the first part is disposed on the second surface of the light guide plate, and the second part runs through the first opening and is disposed on a lower surface of the baseplate. The invention further provides a light-emitting keyboard device.

Embodiments provide a keyboard device having high versatility and high waterproof performance and an electronic device having the keyboard device. A keyboard device has a base plate having a plurality of attachment holes through which a plurality of hook members provided in a body chassis of an electronic device can be passed or with which the plurality of hook members can be engaged in the lower surface, a reflection sheet, which is a sheet-like member covering the lower surface of the base plate, and a plurality of keytops provided on the upper surface of the base plate, in which the reflection sheet is provided with cut lines cut in the thickness direction at positions overlapping with the attachment holes in the vertical direction.

A data entry and/or operating system, particularly a keyboard, also a POS keyboard, includes a lower part and an upper part as well as at least one circuit board and at least one retainer plate, the retainer plate lying on the lower part. One or more bushings are integrated for the purpose of connecting the circuit board to the retainer plate. The upper part is formed from a rubber mat having keys, and the stability of the keyboard is assured by the circuit board, bushing and metal retainer sheet. The lower part is connected to the upper part in a sealed manner.
