Machine-read card free input system

Abstract

The invention relates to an examination tool, in particular to a machine-read card free input system which comprises an answer keyboard, a data storage module, a data analysis module and a data output terminal. Letters or digits on option keys and fragenumber keys of every two adjacent examination positions are arranged in different orders. Transparent organic glass plates the sizes of which are equal to the size of a plane of a liquid crystal display or key are adhered to the surfaces of each option key, each fragenumber key and the microdisplay liquid crystal display. The answer keyboard is connected with the data storage module which is connected with the data output terminal and the data analysis module, and the data analysis module is connected with the data output terminal. The invention saves the examination time and the examination cost caused by the manufacture of machine-read cards and the use of pencils and erasers, and can effectively prevent cheating.

Description

technical field [0001] The invention relates to an examination tool, in particular to a machine-free card-reading input system. Background technique [0002] In the existing various examinations in my country, for the convenience of examination paper scoring, the answering questions for multiple choice questions usually adopt the mode of filling and filling machine to read cards. Since the identification device of the machine-readable card has high requirements on the blackness, shape, and pencil material of the machine-readable card options, in order to ensure that the machine-readable card is not misread, candidates are always careful when filling in. If you make a mistake, you need to use an eraser, so the filling machine takes up a lot of time for candidates to read the card, which is undoubtedly a waste of time. At the same time, for each exam, the total production cost of the machine-readable card and the consumption of pencils and erasers are also a considerable expe...

Since the identification device of the machine-readable card has high requirements on the blackness, shape, and pencil material of the machine-readable card options, in order to ensure that the machine-readable card is not misread, candidates are always careful when filling in. If you make a mistake, you need to use an eraser, so the filling machine takes up a lot of time for candidates to read the card, which is undoubtedly a waste of time

At the same time, for each exam, the total production cost of the machine-readable card and the consumption of pencils and erasers are also a considerable expense.
