Summary:PURPOSE: A hand luggage like a timepiece including a piezoelectric converter to input data manually is provided, which prevents a piezoelectric sensor from being damaged. CONSTITUTION: The timepiece(1) includes a display device(16) displaying more than one data and an upper part including a clock glass(14) covering the display device, and a case(2) formed on a bottom confined by a rear cover(6) placed below the display device. And a piezoelectric converter(32) generating a voltage when a mechanical pressure is applied is installed on the upper part. The voltage generated by the piezoelectric converter is applied to the first electronic circuit generating a logic signal in response to the applied pressure, and the electronic circuit is arranged in the case. The piezoelectric converter is arranged on a bottom of the case and is combined with the case strongly.
