PURPOSE:To produce a sure alarming effect by a method wherein a bell switch is turned ON to start an alarming when a set time is reached and an alarm timepiece rolls within a specified range sounding. CONSTITUTION:When a timepiece A is placed on a flat surface, a ballast wheel 5 is always forced to be at the lowest position by the dead load thereof and a running wheel 53 is meshed with a gear of a running rail 2 so that the ongoing front or rear of the body of the ballast wheel 3 is guided onto a top surface of a guide rail 3 abutting it on the side lower surface thereof. Then, when a set time is reached, a bell switch is turned ON to generate an alarm sound and at the same time, an electrical signal controls the turning ON or OFF of a microswitch 63c through a meter relay 12. Hence, when the switch 63c is turned ON at a set time, an electric circuit is closed to drive a motor 61a on the circuit and a wheel 53 is turned through a transmitting section. Then, the wheel 53 rolls on a rail 2 being meshed therewith and the ballast wheel 5 moves with a guide moving object being guided by the rail 3. Thus, with the shifting of the center of gravity, a case 1 rolls on the rail 2 in a curve. |
