Abstract

The invention provides a scanning bar homing method, a scanning bar homing device and a scanner. A scanner provided by the invention comprises a scanning bar, a manuscript table and a processor, the scanner is also integrated with a near field communication (NFC) card reader and an NFC label, and the NFC card reader is embedded in the scanning bar and is used for reading radio frequency label information and sending the radio frequency label information to the processor; the NFC label is fixedly arranged in a homing area of the manuscript table; and the processor is used for judging whether the radio frequency label information is matched with the radio frequency label information of the NFC label or not after receiving the radio frequency label information sent by the NFC card reader, anddetermining that the scanning bar is successfully reset when judging that the radio frequency label information is matched with the radio frequency label information of the NFC label. According to the scanning bar homing method, the scanning bar homing device and the scanner, successful homing of the scanning bar can be realized.

Description

technical field [0001] The present application relates to the technical field of scanners, in particular to a scanning bar homing method, device and scanner. Background technique [0002] As a digital input device that captures images and converts them into computers that can be displayed, edited, stored and output, scanners have been widely used in various fields. [0003] The scanning bar of the scanner needs to return to the homing area (initial position) after the scanner is powered on or after one scan ends. 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; , it is determined that the scanning bar has been homing successfully. [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 ...
