In the field of education, examinations, as an important way to evaluate students' academic performance, have always been an important part of school education. There are many problems with the traditional way of marking papers. It is not only time-consuming and labor-intensive, but also prone to human errors. In order to solve this problem, a simple and practical technological concept "marking paper scanner" came to mind. Its main components include scanners, image recognition technology and scoring systems. The scanner is the core part of the entire device. It can quickly and efficiently convert paper test papers into electronic documents. The scanner should have the characteristics of high definition, high speed and high precision, and be able to accurately capture every detail on the test paper. The scanner should also have functions such as automatic paper feeding and double-sided scanning to improve work efficiency.

[0003] However, it still has some shortcomings. For example, when using the test paper marking scanner, the test paper often gets stuck, causing the test paper to be damaged. When the damage is more serious, the test paper cannot be recognized and removed, resulting in the inability to record the test results. The jamming phenomenon can also easily cause the scanner to be damaged and need repair, thereby delaying the test paper marking time. These phenomena are usually caused by uneven test papers, curled edges, wrinkles, etc.

[0004] To solve the above problems, this application proposes an English test paper marking scanner. Utility Model Content
