Multifunctional digital machine and correction positioning method for scanning device thereof

Abstract

The invention provides a multifunctional digital machine and a correction positioning method for a scanning device thereof. The correction positioning method comprises the following steps of: monitoring the movement of the scanning device; judging the position of the scanning device; recording a variable according to the position of the scanning device, wherein the variable may be a first numerical value or a second numerical value, and the first and second numerical values represent that the scanning device is positioned in a first area and a second area of a scanning platform respectively; determining the first moving direction of the scanning device according to the variable; controlling the scanning device to perform first moving scanning towards the first moving direction; judging whether the scanning device passes by the correction positioning structure or not in the first moving scanning; and when the scanning device passes by the correction positioning structure, controlling the scanning device to return to a standby position. By the method, time required by the correction positioning of the scanning device can be shortened; in addition, noises produced by the impact of the scanning device on a first terminal and a second terminal of the scanning platform can be avoided, gears of a motor can be prevented from being abraded, and the service life of the multifunctional digital machine can be prolonged.

Description

technical field [0001] The invention relates to a calibration and positioning method of a multifunctional business machine and its scanning device, in particular to a calibration and positioning method of a multifunctional business machine and its scanning device which can avoid loss and reduce noise. Background technique [0002] Generally speaking, in order to ensure that the scanning device can completely scan images such as documents and photos, the multifunctional business machine must first perform calibration and positioning of the scanning device when it is turned on. [0003] see Figure 1A and cooperate Figure 1B , which is a structural schematic diagram of a known multifunctional business machine and a flow chart of calibration and positioning of a scanning device. Such as Figure 1A As shown, the known multifunctional business machine 1 includes a scanning platform 10 and a scanning device 11. The two opposite ends of the scanning platform 10 have a first termi...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a calibration and positioning method for a multifunctional business machine and its scanning device, which defines a reference line on the scanning platform of the multifunctional business machine, so that the scanning platform can be divided into the first area and the second area by the reference line. Two areas, and record different variables according to the position of the scanning device relative to the scanning platform as the first area or the second area, so that the control device can determine the first moving direction of the scanning device according to the recorded variable, so as to shorten the calibration The time required for positioning the scanning device, thereby avoiding the problem of lengthy time for correcting the positioning of the scanning device in the known technology; in addition, the present invention can further stop the scanning device from moving and scanning when the correcting positioning structure is detected, or by controlling the positioning of the scanning device Move the stroke to prevent the scanning device from hitting the first and second terminals of the scanning platform, thereby overcoming the noise problem of the known technology and avoiding the wear and tear of the motor
