PURPOSE:To make it possible to miniaturize a timepiece on the whole by making a keyboard part independent of a reverse cover structure. CONSTITUTION:Key button 1 is fixed being sandwiched between keyboard 2 and keyboard-fixed frame 3 arranged while flank 2a and reverse surface 2b of keyboard 2 are covered entirely. Keyboard-fixed frame 3 between flank 2a of keyboard 2 and body 4 is provided with horizontal interference to fix keyboard 2 to body 4. The lower part of key button 1 of keyboard-fixed frame 3 is formed in a hollow cone shape and under it, projection 3b is provided. This projection 3b pushes up conductive plate 6b of movement 6 to supply circuit substrate 6a with an electric input. |
