PURPOSE:To generate an interruption speedily or slowly in accordance with a moving distance by using a table storing the relations of a lever moving angle of a joy stick, a moving distance and an interruption generating interval to process these variables. CONSTITUTION:Values obtained by A/D converting 2, 3 the X and Y directional changed variables of potentiometers R1, R2 which correspond to the moving angle of the lever of the joy stick 1 are selected by a switch SW1 as an address of a memory 4. The memory 4 is provided with conversion tables T1, T2 storing the relations of the lever moving angles, moving distances and interruption generation intervals. A larger direction out of X and Y directions of the table T2 is selected and A/D converted and the frequency corresponding to the digital value is generated 11 to control a sequence control circuit 17. The output of the table T1 is read out, and only when the lever is moved, an interruption signal RST is outputted from an interruption signal generating circuit 13 through an interface circuit 13. The circuit 13 generates the signal PST slowly at the small lever moving distance or speedily at the large lever moving distance in accordance with the control of the circuit 17. |
