Abstract
PURPOSE: To enable to discriminate the moving direcion of an article correctly by discriminating the moving direction of the article into or out of at least two detectors therebetween when moving between the detectors and producing a discrimination signal when the direction of the article become coincident.
CONSTITUTION: At least two set of detector outputs a1, a2 are applied to a moving direction discriminator 21 to discriminate to store the positive or negative direction of the moving article A into detector sensing area. The positive or negative direction of the article A is discriminated and stored similarly by a moving direction discriminating circuit 27. Further, when the article is moved out of the sensing area via the signals a1, a2, one pulse 3 is produced from a pulse generator 33 to reset at 34 the discriminators 21, 22 by the pulse. The pulse e and the moving direction discriminated result are supplied to a gate circuit 40 to produce positive or negative direction discrimination signals p, n when both direction becomes coincident. Thus, it can correctly discriminate the moving direction of the article of any passing pattern. The number of the moving articles can also be counted by counting the circuit 40.
