Ⅱ “机读卡”是谁发明的
根据网路资料查阅得知中国自80年代从英国引进“微机读卡”技术之后，为客观题的阅卷专，提属供了一个非常实用，快速，有力的解决方案。“微机读卡机器”和卡片也更新换代很快，机读技术现在已经发展成为利用红外线感应炭（石墨）技术！读卡机只对黑色敏感 所以卡上红色绿色的部分读卡机实际是认不出来的卡上原本印有黑色的条块 来帮助读卡机确认卡的方向与位置 铅笔在卡上的填涂的黑块和印好的黑块共同组成了一个只有黑与白的图像 其原理与二进制的"0""1"近似 读卡机扫描后与预先存储的答案生成的图像进行比较 相符的部分就是得分 不符的就是错误。
Ⅲ 答题卡是谁发明的
机读卡，一种简单的光学字符识别(OCR)技术。读卡机只对黑色敏感， 所以卡上红色专绿色的部分读卡机实际是认属不出来的，卡上原本印有黑色的条块 来帮助读卡机确认卡的方向与位置 ，铅笔在卡上的填涂的黑块和印好的黑块共同组成了一个只有黑与白的图像。 其原理与二进制的 0 1 近似，读卡机扫描后与预先存储的答案生成的图像进行比较 相符的部分就是得分， 不符的就是错误。 侧面有一条黑白相间的道，叫导引道。 然后用光电元件测量光通量，再通过数字处理，就可以得出分数。这样速度快而且准。 光电读卡机的工作原理是通过机器光电头对信息的识别来录入有关信息自动判断正误。
