タイトルまたは説明

An Optical Mark Reader is simply a machine that takes sheet paper and records whether marks appear on the paper in predefined areas. OMR machines are not scanners in the sense that they do not form an image of the sheets that pass through .Instead, the OMR device simply detects whether predefined areas are blank or have been marked. The fact that OMRs don’t form an image differentiates them from desktop scanners that are often used to scan photos or documents. OMRs have the capacity to read sheets at a very high rate. The OMR machines can be used at somewhere large amounts of data entry, statistics and analysis is required. The model we have can read about *5~*0 sheets per minute. The slip’s width can be ranged between *9mm/3.*1in and **0mm/8.*7in.
