Title:
INFORMATION INPUT DEVICE
Document Type and Number:
Japanese Patent JPS60256881
Kind Code:
A
Abstract:
PURPOSE:To detect and process accurately the input information despite its variation of two times by outputting the new input information after correcting it to be equal to the present information in case the difference is detected between the preceding information and the present information as well as the present information and the new input information, respectively. CONSTITUTION:The information issued from a transmission device 1 is supplied to an input device 2 at a prescribed short time interval. A correction circuit 6 in the device 2 performs comparison among the present information B of the 1st memory circuit 4, the preceding information C of the 2nd memory circuit 5 and the new input information A respectively. If bits are different between the information C and B and information B and A, the bits of the information A is corrected so that they are equal to those of the information B. Then the information A is outputted. At the same time, the information B is rewritten to the information A and sent to a processor 3. The circuit 6 rewrites the bits of the information A in the form of those of the information B in case the result of comparison among three types of information is quite unique.
