PURPOSE:To discriminate noise easily, reduce cost and improve reliability of an automatic machine by providing an interrupt pulse oscillator that shifts a receiving element, a storing element of input signal and a signal periodically in the storing element. CONSTITUTION:Input signals are received by a receiving element 1 and stored by a storing element 2, and at the same time, shifted in the element 2 through an interrupt pulse oscillator 3. That is, input signals n1-nm are received the element 1 and stored in LSB (Bit 0) of designated address of the element 2. Input signals stored in the element 2 are shifted to the left by the oscillator 3 at all times. For instance, supposing that period of interruption is 10ms, it can be judged at high probability that input signals held the level of 1 during 20-30ms when all of bits 1, 2, 3 are 1, and can be distinguished easily from noise signals inputted in edge-like form. As noise can be discriminated easily by software, cost can be lowered reducing material expenses etc., and at the same time, reliability of an automatic machine can be enhanced. |
