본 발명은 입학시험을 비롯하여 각종 시험 답안지로 사용되고 있는 오엠알카아드의 정밀판독장치에 관한 것으로 보다 구체적인 특징은 판독장치를 정밀하게 만들어서 카아드상에 정답표기가 잘못되었다는 것을 알았을 때 먼저 표기한 표기란의 잉크면적보다 더 넓은 면적으로 잉크를 칠해 정답을 표기하므로써 표기의 자동정정이 가능하고 이로 인해 수험자가 보다 적은 부담으로 시험에 임하여 만족스런 실력발휘가 가능케한 것이다.The present invention relates to the precision reading device of Om al-Qaad used for various test answer sheets including the entrance examination, and more specifically, the notation mark marked first when the correct answer marking is made on the card by making the reading device precise By correcting the answer by marking the ink with a larger area than that of the ink, the automatic correction of the marking is possible, which allows the examinee to perform satisfactorily with the test with less burden.
종래의 오엠알카아드 판독기는 해답표기용 4개의 공란중 어느 한곳에만 잉크칠을 해야하므로 잘못 표기한 사실을 발견한다해도 이를 정정하기가 매우 까다로워 많은 부담을 가져야 하는 불편이 있었다.Since the conventional Om al-Qaard reader has to ink only one of the four blanks for answer marking, it is very difficult to correct it even if it finds a mislabeling fact and has a lot of inconvenience.
본 발명은 위와 같은 종래의 결점을 시정하여 정밀한 판독이 가능케한 것인바 이를 보다 상세히 설명하면 다음과 같다.The present invention is to correct the above-described drawbacks to enable precise reading bar as described in more detail as follows.
투광기(가)와 수직으로 위치한 광전류검출기(나)사이에 오엠알카아드(라)를 횡삽하여 수광부에 감지된 광전류차이가 전압차이로 나타나게 부호별로 연결시킨 오엠알카아드 장치에 있어서 1차적으로 광전류검출기(나)에 의하여 검출된 전압을 세분하여 오퍼엠프(바)로 입력하고 비교회로를 농해 선택된 전압신호가 AND게이트(아)로 출력되어 기존콤퓨터(자)에 연결되게 한 장치이다.The photocurrent detector is primarily used in an OEM al-Qard device in which OM al-Qaard (D) is interposed between the transmitter (A) and the photocurrent detector (B) positioned vertically so that the photo-current difference sensed by the light-receiving unit is connected by a code. It is a device that divides the voltage detected by (b), inputs it to the offer amplifier (bar), concentrates the comparison circuit, and outputs the selected voltage signal to the AND gate (a) to be connected to an existing computer (child).
이와 같이 된 본 발명은 오엠알카아드(라)에 배열된 정답표기공란 정답을 표시함에 있어서 처음은 잉크면적이 적게하고 검산후에 확인하는 과정에서 잉크면적을 더 키우는 방법으로 표기를 할 수 있고 처음 표기가 잘못되었을 경우는 다른 정답란에 정답표기를 하면서 먼저 표기한 부호의 잉크면접보다 넓게만 표기하면 정답표기가 되기 때문에 오엠알카아드 작성에 별다른 부담을 느끼지 않아도 되는 장점이 있고 본 발명과 같은 장치를 통해 오엠알카아드를 판독하므로써 투광기에서 투사된 빛이 광전류검출기(나)에 수신되어 전압차이로 나타나는 신호는 잉크표기면적의 차이에 따라 모두 다르게 나타나지만 잉크면적을 가장 넓게 칠한 부호의 전압이 가장 크게 나타나서 이것이 비교회로를 통해 전압이 높은 쪽으로 출력이 나오고 AND 게이트(아)의 출력을 유도하게 되므로 해답을 이곳저곳에 표기했다 하여도 가장 크게 칠한 부분의 부호가 해답표시 의사로 나타나서 정밀한 판독이 가능케하고 수험자가 안심하고 오엠알카아드를 작성할 수 있도록 되는 이점이 있는 것이다.In the present invention as described above, in displaying the correct answer blanks arranged in the Om al-Qaard (D), the ink area may be initially marked with a method of increasing the ink area in the process of confirming that the ink area is small and after checking. If is wrong, the correct answer is written in the other correct answer column, and only if the wider than the ink interview of the first written mark is the correct answer because there is an advantage that you do not have to feel much burden in writing Om al-Qaard and through the same device as the present invention By reading OM alkaad, the light projected by the emitter is received by the photocurrent detector (b) and the signals appearing as voltage difference are all different according to the difference of ink surface area, but the voltage of the sign with the largest ink area is shown. Through the comparison circuit, the output goes to the higher side and the AND gate Since the output is derived, even though the answers are marked here and there, the sign of the largest painted part is shown as the intention to display the answer, which enables the precise reading and allows the examinee to write Om al-Qard with confidence.
