Apparatuses and systems that include a keyboard baseplate including a concave structure with a logic substrate housed therein are disclosed. One apparatus includes a keyboard baseplate including a concave structure formed thereon and a lower surface having a side. The apparatus further includes a logic substrate provided on the side of the lower surface of the baseplate and housed within the concave structure. The logic substrate is configured to receive an analog signal generated by a sensor and convert the analog signal to a digital signal.

Keyboard baseplates including a concave structure for housing a logic substrate

A keyboard device is provided with a base plate configured by arranging a plurality of plate members, a plurality of keytops vertically movably supported on the upper surface side of the base plate, a frame attached to the upper surface side of the base plate and having a plurality of hole portions into which the keytops are vertically movably inserted, and a fastening tool provided at a position overlapping with a plate boundary portion formed between the facing end surfaces of the plate members adjacent to each other and simultaneously fastening the adjacent plate members to the frame.

Keyboard device and electronic apparatus

A keyboard device is provided with a base plate, a plurality of key tops, a membrane sheet, and a frame. The frame has a frame portion interposed between the key tops adjacent to each other and partitions each key top in a vertically movable state by the formation of a gap between the side surface of the frame portion and the side surface of the key top. The base plate has a notch portion at a position at least overlapping with a portion under the gap.

An input device includes a base plate and a push button rotatably provided on a top surface of the base plate. The base plate has a bearing part protruding from the top surface. The push button has an operation surface part receiving a push down operation and a positioning part rotatably supported by the bearing part. The positioning part positions the push button in the plate thickness direction of the bearing part by an abutting part abutting on a first face of the bearing part and a pushing part resiliently biased toward and pushing a second face of the bearing part.
