Problems solved by technology

[0002] There are two types of scanners: flatbed and automatic feeding. The flatbed can only scan a single sheet, which is less efficient and is suitable for a small number of scans. The automatic feeding is more convenient, but often there will be multiple sheets of paper. If If the scanner does not stop in time, there will be a paper jam, which may seriously damage the paper

Abstract

The invention discloses a circuit control device for a scanner. The circuit control device comprises a control unit used for controlling the whole scanner, a lamp tube used for irradiating light to a document to be scanned, an image sensor used for collecting the document to be scanned of a user, an analog-digital converter used for converting a received image to a digital signal, a storage unit used for temporarily storing data, a motor, a drive unit used for driving the motor to drive, an ultrasonic unit used for detecting whether more sheets of paper is fed and an electrostatic protection unit used for preventing static electricity from being overlarge to destroy the device, wherein the drive unit, the analog-digital converter, the storage unit, the ultrasonic unit, the lamp tube and the electrostatic protection unit are all connected to the control unit; the other end of the analog-digital converter is connected to the image sensor, and the other end of the drive unit is connected to the motor. According to the circuit control device, by adopting the ultrasonic unit used for detecting whether more sheets of paper is fed, when more sheets of paper is fed, the scanner automatically stops to prompt the user to feed the paper again, so that the paper jam condition due to feed of more sheets of paper is avoided.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a scanner circuit control device. Background technique [0002] There are two types of scanners: flatbed and automatic feeding. The flatbed can only scan a single sheet, which is less efficient and is suitable for a small number of scans. The automatic feeding is more convenient, but often there will be multiple sheets of paper. If If the scanner does not stop in time, paper jams may occur, which may seriously damage the paper. Contents of the invention [0003] The purpose of the present invention is to provide a scanner that automatically stops when multiple sheets of paper are fed, and prompts the user to reload the paper. [0004] The present invention is achieved through the following technical solutions: a control unit that controls the entire scanner, a lamp tube for irradiating light to the document to be scanned, an image sensor for collecting the document to be s...
