Abstract
PURPOSE:To make unnecessary a clutch and a limit switch, by interrupting power between the brushes of a motor through the axial movement of a rotary shaft, when an antenna element is finished for the operation of extension and contraction and the wheel stops rotation. CONSTITUTION:When switches S1, S2 of a power supply circuit are connected to the position of S1U, S2U, a closed loop is formed among power supply E, brush B1, commutator 7, armature 5, brush B3 and power supply E, and a main body 1 turns forward. Thus, the torque of the main body 1 is delivered to a wheel 21 via a worm 11 and a wire driving wheel 22 turns toward the arrow. Then, when a driving wire is introduced and an antenna element A reaches a limit of extension or contraction, the wheel 21 is disable for rotation. Thus, when a rotary shaft 6 moves downward and an insulating ring 8 of the commutator 7 moves to the position of the brush B1, the conduction between the brush 1 and the commutator 7 is interrupted and the main body 1 stops for the rotation. Next, when the switches S1, S2 are switched to the contacts S1D and S2D, the element A goes downward and the main body 1 is stopped at the limit.
