PURPOSE:To elevate the station selective accuracy by setting to an acute angle the angle which is made by the moving direction of one horizontal moving plate which moves horizontally butting against one butt part at the time when the station selective member slides, and the sliding direction of the station selective member. CONSTITUTION:When the push-button 9 is pushed, the arm 1 goes forward against the spring 19 through the link piece 8, and at first butts against the tilted edge 14a opposed to the other butt part 3a. And the horizontal moving plate 13a moves horizontally to the left, the other horizontal moving plate 13b moves horizontally to the right through the rotary piece 17, and the tilted edge 14b provided on it is forcibly butted against the butt part 3b opposed to it. When both the butt parts 3a and 3b have butted against the opposed tilted edges 14a, 14b, it is obstructed that the arm 1 goes forward, and the variable tuning element is varied in accordance with the horizontal moving displacement extent of the horizontal moving plates 13a, 13b, which is decided corresponding to the rotary angle of the specified member 4, by which it is attained to select a station. |
