Key operating device of key board
专利汇可以提供Key operating device of key board专利检索，专利查询，专利分析的服务。并且PURPOSE: To facilitate key operation and to lighten the fatigue of fingers, by working a plurality of keys mounted to a key board by means of a joy-stick device in place of operation pushed by fingers.
CONSTITUTION: When pushing an upper end 22 of a first handle 24 in the arrow head D direction, a key 165 is pushed because a nose 23 projects against the force of the elasticity of a spring 52. In this case, each contact portion 30L, 30R, 30F, 30B is under conditions that each contact portion does not push corresponding any key 164, 166, 162, 168. When the pushing of the first handle 21 is removed and the second handle 24 is brought down in the arrow head L direction, a bowl body 27 slides on a bowl body receiver 33 of a bottom 31, a semispherical body 26 turns along an inner circumferential surface of a semispherical body receiver 42 of an upper plate 32 and the contact portion 30L pushes the key 164. When bringing down the handle 24 in the arrow head R direction, the contact portion 30R pushes the key 166; when in the F direction, the key 162; when in the B direction, the key 168. This device is effective for video game apparatuses.
