When scanning drawing, you can scan the answer sheet with two B pencils. The answer sheets are all multiple-choice questions, scrawled with 2B pencils. There are fill-in-the-blank questions and calculation questions on the answer sheet. You don't need a pencil to draw on the answer sheet, because machine scanning is like a projector, which enlarges the test paper to the screen and then corrects it by the teacher instead of directly correcting it by the computer. Just organize and write clearly.

Extended data

fundamental/essential component

The answer sheet is generally composed of basic information column, guide rail and many information bits.

The basic information column is generally used to fill in the basic information of the user who fills in this card. The general exam includes the name and test number of the candidate. The guide rail is used for readers to confirm the direction and position of the answer sheet. The information bits occupying most positions are for users to fill in the options they choose.

After answering the question, the information on the answer sheet is recognized by the optical marking instrument, and the smearing data is input into the computer through the supporting software.

production requirement

Optical tag readers require high positioning accuracy of all the read parts on the information card, so there are many requirements for making answer sheets. It requires that the paper fiber used should be long, the paper thickness should be uniform, the stiffness should be good, the sizing degree should be high, the smoothness should be good, the thermal expansion and contraction should be uniform, and the printing overprint and the cutting accuracy of the reference edge should be high.

Only when the above conditions are met, when reading the answer sheet, readers will not block the photoelectric head due to poor papermaking raw materials and low sizing, resulting in reading errors, will not produce a large number of double sheets and paper jams during continuous reading due to uneven paper thickness, poor stiffness and smoothness, and will not be unable to read or make reading errors due to excessive paper shrinkage or low printing and cutting accuracy.
