<p>PURPOSE:To impart a handle operating sense to an operator in a joy stick device for operation of a simulator or the like. CONSTITUTION:The lower edge part of a handle 20 of a joy stick device is fixed through shaft to a supporting point pin bracket 12 fixed to a supporting stand 10 so as to be swinging, and the handle 20 is held by a pair of coil springs 27 at a neutral position. On the other hand, a reciprocating type hydraulic cylinder 35 is engaged with the middle part of a lever 22 of the handle 20, and each top end of piston rods 36a of the both sides of the hydraulic cylinder 35 is fixed to the supporting stand 10. Then, at the time of the inclining operation of the handle 20 by the operator, a resistance due to the compression of oil in the hydraulic cylinder is generated, and the handle operating sense can be imparted to the operator by the resistance. And also, the both sides of the hydraulic cylinder 35 are connected by a by-pass pipe line having a diaphragm valve in the middle, and the optimal operating sense can be imparted to the operator by the adjustment of the extent of diaphragm of the diaphragm valve.</p> |
