Problems solved by technology

[0002] At present, in the process of correcting homework in schools, the answers are often mixed up, especially in the correction of objective questions, it is easy to make mistakes. Although there are objective question answer card scanners, the correction speed has been improved a lot. When the scanner is expensive, use The number of times is not much, which is easy to cause waste. In addition, in some rural schools, there is no such equipment. Another disadvantage of the scanner is that students must paint neatly within the range. limitation

Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings. Such as figure 1 As shown, a correction ruler includes a ruler plate 1 and a numerical value. At least ten rows of holes 2 are arranged on the ruler plate 1, and a shield 3 is pasted on each row of holes 2. The shape of the shield 3 is suitable for the shape of the holes 2. Matching, the holes 2 are evenly arranged on the ruler plate 1.

[0009] Find a ruler board 1, make the size of the ruler board 1 the same as the size of the answer sheet, overlap the ruler board 1 and the answer sheet, and then mark the overlapped position, after marking, the square hole 2 can be drawn out with an instrument, and when correcting , paste a square mask 3 on the correct answer option, put the ruler board 1 on the answer sheet, if you do not see other alteration options, it is correct, if there are other answers, it is an error, and make a mark on the square hole 2 red mark.

Abstract

The invention discloses a correction ruler comprising a ruler plate and numerical values, wherein at least ten rows of holes are formed on the ruler plate, masks with shapes matched with that of the holes are pasted on each row of holes, and the holes are averagely formed on the ruler plate. By adopting the correction ruler with the structure, the ruler plate is designed to have the same size as an answer sheet, the parts of the ruler plate coinciding with options are hollowed to form holes, and at least ten rows of holes are formed on the ruler plate. The correction ruler improves the correction efficiency and reduces the correction cost, and a student needs not to be too normalized in answering, and only needs to answer in an answer range, thus saving the answer time of the student.
