Automatic examination question correcting and marking device

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 identifies test questions on test question paper for automatic correction and performs mark leaving correction on the test question paper according to an automatic correction result; the test question correcting and mark-leaving mechanism comprises a correcting pen mark-leaving assembly, the correcting pen mark-leaving assembly comprises a correcting pen, an X-axis driving component, a Y-axis driving component and a Z-axis driving component, and the correcting pen is driven by the X-axis driving component, the Y-axis driving component and the Z-axis driving component jointly to conduct mark-leaving correcting on test question paper. The test question correcting and mark leaving mechanism of the test question automatic correcting and mark leaving device can achieve automatic correcting of test questions, and mark leaving correcting is conducted on test question paper according to the automatic correcting result through the correcting pen mark leaving assembly; the correction pen mark-leaving assembly drives a correction pen to move in the space through an X-axis driving part, a Y-axis driving part and a Z-axis driving part, the mark-leaving correction effect of manual correction is simulated, and the correction pen mark-leaving assembly is more real.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a device for automatically correcting and leaving marks for test questions. Background technique [0002] School education, as the main way of learning scientific and cultural knowledge, in order to help students master the knowledge, homework and exam paper practice are essential.
