PROBLEM TO BE SOLVED: To miniaturize a keyboard constitution.SOLUTION: A pressing constitution of a thin keyboard is constituted by a circuit board 1 having a plurality of trigger parts 11 respectively triggered to generate keyboard signals and a frame 2. The frame is integrally formed with an outer frame 21 laid on the circuit board and having a plurality of storage areas installed so as to correspond to the respective trigger parts, a plurality of inner frames 22 and a plurality of key tops 23 installed in the storage area so as to respectively correspond to one of the trigger parts. The space between the outer frame and the key top is connected by each inner frame. Each inner frame includes at least two first connection parts 221 connected to the outer frame and at least two second connection parts 223 connected to the key top and continuously includes support parts 222 which constitute a process of transition of the key top to the trigger part with generation of elastic deformation between each first connection part and each second connection part.SELECTED DRAWING: Figure 2 |
