Problems solved by technology

[0004] When the above method is used to return the scanning strip, due to the internal dirt of the scanner or the unclear calibration pattern, etc., when the scanning strip returns to its position, the calibration pattern cannot be scanned or the scanned stain is mistaken for the calibration pattern, resulting in The scanning bar cannot be successfully returned to the original position

Abstract

The present application provides a method, device and scanner for homing a scan bar. The scanner provided by this application includes a scanning bar, a manuscript table and a processor, and the scanner is further integrated with a near field communication NFC card reader and an NFC tag, wherein the NFC card reader is embedded in the scanning bar NFC tag is used to read the radio frequency tag information and send the radio frequency tag information to the processor; the NFC tag is fixedly arranged in the homing area of ​​the manuscript table; the processor is used to receive After receiving the radio frequency tag information sent by the NFC card reader, determine whether the radio frequency tag information matches the radio frequency tag information of the NFC tag, and when determining that the radio frequency tag information matches the radio frequency tag information of the NFC tag, Make sure the scan bar is successfully homing. The scanning bar homing method, device and scanner provided by the present application can realize the successful homing of the scanning bar.

Description

technical field [0001] The present application relates to the technical field of scanners, and in particular, to a method, device and scanner for returning a scanning bar. Background technique [0002] Scanners have been widely used in various fields as a digital input device that captures images and converts them into digital input devices that can be displayed, edited, stored and output by a computer. [0003] The scanning bar of the scanner needs to return to the home area (initial position) after the scanner is powered on or after a scan is completed. At present, the commonly used scanning bar homing method is: setting a calibration pattern (for example, the calibration pattern is a black dot) in the homing area of ​​the platen; , then it is determined that the scan bar is successfully reset. [0004] When the above method is used to return the scanning bar, due to the internal dirt of the scanner or the unclear calibration pattern, when the scanning bar is returned to...
