INPUT OPERATION DEVICE

WIPO Patent Application WO/2005/101437

A1

An input operation device capable of detecting an input operation in the lateral direction and multiple stages of input operations in the longitudinal direction with less number of switching elements. Front, left, rear, and right side switches (141) to (144) are opposed, from the lower side, to the center front part (131), right front part (132), center rear part (133), and left rear part (134) of an input operation member (120) swingable in the longitudinal and lateral directions and energized to the center position. When the input operation member (120) is tilted leftward, the left side switch (144) is turned on, tilted rightward, the right side switch (142) is turned on, tilted forward, the front side switch (141) is turned on and then the right side switch (142) is turned on, and tilted backward, the rear side switch (143) is turned on and then the left side switch (144) is turned on. Despite the fact that the number of the switching elements is only four, two stages of input operations in the lateral and longitudinal directions can be detected.
