PURPOSE:To improve reliability by removing the mis-operation of an operator or an error in a signal generation processing system, by taking the logical product of storage under selection and an auxiliary code storage part, and informing it to the operator. CONSTITUTION:By operating either selection designating switches 221-224 in a selection command part 22 by the operator, corresponding flip-flop out of flip-flops 181-184 in the auxiliary code storage part 18 is latched by a selection designating signal, and also, the selection designating signal is stored in an under selection storage part 20. The latched output of the auxiliary storage part 18 is inputted to AND gates 211-214 in an AND part 21, and also, a corresponding selection designating signal is inputted from the under selection storage part 20, and the AND gates 211-214 issue output signals by taking the logical product of input condition, and a corresponding selection display lamp out of the lamps 171-174 in a selection display part 17 is lit. Therefore, the operator M can decide whether a selected content is correct or not by the display state of the selection display lamps 171-174.
