摘要： PURPOSE:To avoid sending the erroneous data to the processor by disregarding the erroneous data in case the continuous coordinate value is read out mistakenly, thus omitting the data check at the processor. CONSTITUTION:Reading data 10 of the coordinate value read out first is stored into the 1st register 11 via reading pulse 14 which is supplied simultaneously. Then data 10 stored in register 11 is stored into the 2nd register 12 via the reading pulse which is delayed by the fixed time through delay circuits 15 and 16. The comparison is given through comparator 13 between reading data 10 of the coordinate value which is supplied continuously and reading data 10 which was read precedingly and stored into register 12. And in case the difference of the absolute values is within the fixed range, the logic product of AND gate circuit 17 is set up by the output of comparator 13 to deliver data strobe pulse 18. While in case the difference of the absolute values exceeds the fixed range, the logic product of circuit 17 is not set up. Thus the transmission of the erroneous data is inhibited to the processor.

摘要： PURPOSE:To avoid sending the reading data to the processor by deciding it as the erroneous data in case the continuous coordinate value is read mistakenly or the light pen gets out of the basement board, thus omitting the data check at the processor. CONSTITUTION:Reading data 10 of the coordinate value is stored into the 1st register 11 via reading pulse 14. And data strobe pulse 20 is transmitted to the processor via AND gate circuit 19 in the case of the first data 10. Pulse 20 is then applied to the 2nd register 12 after the delay given by delay circuit 17 in the fixed time, and the data of register 11 is stored into register 12. At the same time, control circuit 16 which controls OR gate circuit 18 with pulse 14 used for the input is provided. And then the comparison is given at comparator 13 between the continuous coordinate value stored in registers 11 and 12. And in case the difference of the absolute value is within the fixed range, the logic is set up for circuit 18 to deliver pulse 20. While in case the light pen gets out of the basement board, the logic is not set up by the output of circuit 16 to inhibit the transmission of pulse 20.
