Automatic test question correcting and mark leaving device and control method thereof

Abstract

The invention discloses an automatic test question correcting and mark leaving device which comprises a test question correcting and mark leaving mechanism which collects and recognizes test questions on test question paper for automatic correction and performs mark leaving printing on the test question paper according to an automatic correction result; the test question correcting and mark leaving mechanism comprises an array type seal assembly and a seal driving assembly, the array type seal assembly comprises a plurality of seal single bodies which can be independently driven to move in the preset direction, and the seal single bodies move downwards to conduct mark leaving printing on the test question paper; the seal driving assembly comprises electromagnets in one-to-one correspondence with the seal single bodies, and each seal single body is provided with a permanent magnet. According to the test question automatic correcting and mark leaving device, the electromagnet is controlled to be powered on to generate the electromagnetic field, and the permanent magnet on the seal single body is subjected to the magnetic force effect in the electromagnetic field to drive the seal single body to move in the preset direction.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a device for automatically correcting test questions and leaving marks and a control method thereof.
