PURPOSE:To obtain a prioritized digital signal output by a simple combination of modules and to improve reliability by exluding signals from a maximum digital signal to a minimum one from an object to be sequentially sorted and designating the object. CONSTITUTION:Plural digital signals 100 input to a digital signal sorting-out circuit 1. Among them the digital signal 101 showing the minimum is outputted, and simultaneously a minimum display signal 102 corresponding to the signal 101 is outputted. The minimum display signal 102 is impressed on a control circuit 2, from which a control signal 103 holding the value of the signal 102 is outputted. The signal 103 reaches the digital signal sorting-out circuit 1, inputs a control terminal corresponding to the minimum display signal 102, and is held as the impression signal of a terminal in the digital signal sorting-out circuit 1 until a next signal to be sorted out comes in. Then the digital signal 101 showing the maximum and the minimum display signal 102 are outputted in a similar manner, and continuously the digital signal showing the maximum is outputted, whereby the prioritizing action of the inputted digital signals is completed.
