Claims

[Scope of utility model registration request]

(1) An operating section for turning on/off a power switch in a transmitter/receiver etc. equipped with an antenna element and switching an extension degree designation switch for causing the above-mentioned tentenna element to extend to one full extension or one specific intermediate extension, and from this operating section. a control signal forming section that forms a predetermined control signal according to a signal of the antenna element; a reversible motor that causes the antenna element to expand and contract; a motor drive section that rotates the reversible motor forward or reverse; a pulse train forming unit that forms a pulse train based on the rotation of the drive motor; a target value setting unit that sets a target value signal based on a control signal from the control signal forming unit; and counting the pulse train formed by the pulse train forming unit. and a comparison/judgment means for comparing the target value signal and the count value signal and giving commands for forward rotation, reverse rotation, and stop to the motor drive section based on the comparison result. a calculation control unit that operates based on a signal from the operation unit and a response signal from the calculation control unit, activates the calculation control unit during the expansion/contraction operation of the antenna element, and activates the calculation control unit after the expansion/contraction operation of the antenna element is performed. An electric antenna expansion/contraction control device, comprising: a power supply section that supplies power to the arithmetic and control section so as to deactivate the arithmetic and control section.

(2) The electric antenna expansion/contraction control device according to claim (1), wherein the arithmetic control section is a microprocessor comprising a one-chip LSI.
