Abstract
The invention relates to a high-speed sheet document image computer input device which is a mechanical and electrical device for inputting sheet documents (including but not limited to examination answer sheets) into a computer at high speed. The high-speed sheet document image computer input device is composed of a paper feed part, a lighting circuit, a camera head and a capture software, wherein, the paper feed part utilizes a motor to drive a pickup roller to continuously moving paper out by a transmission mechanism; the lighting circuit assists the camera head to obtain a satisfied image. The computer capture software utilizes the image recognition technology to judge the time that the former piece of paper is fully moved out and the later piece of paper is not moved by monitoring the movement of the paper by the camera head, the later page of document is captured, and the image is saved in a document folder of the computer in real time, thereby realizing the continuous scanning of sheet documents.
Description
Technical field
The present invention is that a kind of page document (including but not limited to test answer sheet) that will fall apart is input at a high speed the electromechanical equipment of computer, with respect to scanner speed, improve approximately 20 times of (scanner speed one page A4 paper approximately 10 seconds, one page A4 paper of the present invention approximately 0.5 second), can automatically deposit continuously the document electronic image in computer file, be particularly useful for college entrance examination, in examine the occasion of extensive collective computer marking.
Background technology
At present, known scanning device is scanner, consists of upper cover, document board, optical imagery part, photoelectric conversion section, mechanical driving part.Optical imagery is partly scanner " eyes ", is used for obtaining the optical information of original copy reflection.For the light of assurance image reflection is enough strong, provide required light source by a cold cathode fluorescent lamp.The fluorescent tube temperature of operation after a period of time of just having started working raise gradually by low, before and after causing, the scanning effect has gap, a lot of scanner specifications all say that scanner can reach more satisfactory effect in work after 10～30 minutes, and the pre-hot standby of starting shooting is to obtain the helpless selection of scanner ideal effect.Another problem of scanner is that CCD does mechanical movement back and forth, affects sweep speed and useful life.Although autoamtic paper feeding type High Speed Document scanner is arranged now, and its sweep speed is 20ppm-160ppm, day output 1500-6000 page, day output in the price more than ten thousand all more than 100,000 yuan.
Summary of the invention
Scanner needs preheating, sweep speed is slow, useful life is short and the expensive deficiency of autoamtic paper feeding type High Speed Document scanner in order to solve, the invention provides a kind of mode of the imaging of taking pictures continuously fast, utilize camera (or digital camera) to catch image, can greatly improve sweep speed and useful life, not need preheating can reach stable effect.According to preresearch estimates, product price of the present invention, about below 20,000 yuan, has obvious competitive advantage on price.
The technical solution adopted for the present invention to solve the technical problems is: effectively utilize lever principle to make the platen constant pressure of paper-sheets rolling wheel, than routine, use the platen effect stability of spring.Specific embodiments is: balance pivot is fixed on the original copy platen, and lever one end is paper-sheets rolling wheel fixedly, and the other end is adjustable weight, and motor is fixed on lever, utilizes the deadweight platen of paper-sheets rolling wheel, rotating shaft and transmission device.Utilize motor to drive the continuous paper feed of paper-sheets rolling wheel by transmission device.Computer software monitors that paper moves, and uses image recognition technology, in preceding sheet, has removed then a piece of paper fully and has captured the next page document when not yet moving, and deposited in real time the computer documents folder in, realizes the continuous sweep of loose page document.
The invention has the beneficial effects as follows, utilize camera (or digital camera) to catch image, can greatly improve sweep speed and useful life, utilize lever to make the platen constant pressure of paper-sheets rolling wheel make the paper feed effect stability phenomenon of paper (in the time of can not the producing paper feed with), in addition, simple in structure, do not need preheating, with low cost be advantage of the present invention place.
