<p>PROBLEM TO BE SOLVED: To easily project an antenna section from a container by providing a lock section that can be moved to a lock position at which projection of the antenna section from the container is prevented or to a permissible position at which projection of the antenna section from the container is permitted and an operation section to an antenna system. SOLUTION: Engagement between a lock section 128 and a recessed part 127 is released by depressing an operation button 115 in a direction (clockwise direction) so as to enter a groove 113 of a stator section 102 against an energizing force of a coil spring 114. Thus, a 1st antenna section 117 and a 2nd antenna section 118 are projected from the container 118 with an energizing force of coil springs 120, 121, resulting in being projected from a portable telephone set. Then the 1st antenna section 117 and the 2nd antenna section 118 can easily be projected from the portable telephone set by conducting a simple operation that is depression of the operation button 115. When the operation button 115 is released while the antenna sections 117, 118 are projected from the container 119, the lock section 118 locks the antenna sections 117, 118.</p> |
