ABSTRACT:
A keyboard is hinged at the front end of the main body of an electronic apparatus. The keyboard swings around the hinge section to have a folding position in which it is raised upright against the front face of the main body and an operating position in which it is laid down in a virtually horizontal attitude. The keyboard incorporates a key switch circuit board on which a matrix of electrical contacts is formed, and the main body incorporates a main controller board for the electrical apparatus. A connecting printed circuit board is used to connect the signal lines of the key switch circuit board to the corresponding signal lines of the main controller board. The connecting printed circuit board is flexible, and is bent when the keyboard takes one of the folding position and operating position. Its bend is relaxed when the keyboard takes the other position.
