ABSTRACT:
A button, having two end portions along a particular direction that can be selectively depressed, is supported by a support member. Pins are formed on the support member at locations corresponding to the respective two end portions of the button, the axes of the pins being perpendicular to the direction of depressing of the button. Elongate apertures are formed on the button in locations corresponding to the respective pins, the elongate apertures configured to have the pins slidably fitted therein and having their lengthwise directions generally parallel to the direction of depressing. A biasing unit is further provided to bias the button in a direction opposite to the direction of depressing. When the button is in a neutral condition, the button is biased by the biasing unit so that the pins are located respectively on one side of the elongate apertures. When one of the two end portions of the button is depressed, the button swings against the biasing force of the biasing unit using the pin located on the other of the two end portions of the button as the supporting point.
