PURPOSE:To drive an oscillating circuit as required only, by inserting a contact of a hold switch operated by a signal of an AND circuit to a power supply circuit of a radio circuit. CONSTITUTION:An acceleration sensor 1 outputs a voltage proportional to the acceleration. When the output of the acceleration sensor exceeds a threshold value of a discriminator 2, the output of the discriminator 2 is at H level, a timer 3 is converted into an L level and a hold switch 6 is operated by an output signal of an AND circuit 4, the contact 7 inserts the power supply circuit 9 of a radio circuit 8 and an automatic oscillation radio is driven. |
