Description

Picture and text digitizer paper feed mechanism

Technical field

The utility model relates to graphics context collection device in a kind of camera work, more particularly, relates to the conveying mechanism of a kind of paper media wherein.

Background technology

At present, equipment in high speed, paper media digitized processing field extensive use in batches is the high speed scanner of band automatic paper feeder, it has two types, a kind of is the CCD type, utilize CCD/CMOS as sensitive component, carry out linear scan, by a series of lens, speculum imaging, so can produce color error ratio and optical aberration, generally need carry out colour correction by scanning software, released the technology that multirow CCD scans simultaneously in recent years, be applied in the high speed scanner, but cost had improved thereupon; Another kind is a CIS contact scanner, adopts and presses nearly original copy mode to scan, and scanning accuracy is lower, its light source uses the LED light-emitting diode, this light source is all poor on photochromic and the uniformity, and colour gamut is narrow than CCD, and the color of acquisition is abundant not as CCD's.These two kinds of scanners are all in conjunction with the ADF automatic paper feeder, the high speed paper feed.Because the restriction of scanner operation principle, raising speed are simultaneously, increased the cost of scanner greatly, cause holding at high price of high speed scanner, and necessary online use, the storage underaction.Chinese patent ZL200720093864.8 discloses a kind of picture and text digitizer new product, and performance is good, clear picture, and color error ratio is little, optical aberration is little, and information storage is flexible, and price is low, and is easy to operate, shortcoming is manually to send picture and text paper, puts one by one, and speed is slow, and efficient is low.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of picture and text digitizer paper feed mechanism is provided.

ZL200720093864.8 picture and text digitizer is that optics one-time imaging and CCD/CMOS sensitive component are combined, and it is fast to have an image taking speed, and off line is used, the storage flexible characteristic.The technical solution of the utility model is on the basis of existing picture and text digitizer, combines the automatic paper feed of ADF system, with automatic paper feed system and imaging switch gearing, realizes the digitized processing of High-Speed Automatic batch paper media by position transducer.

A kind of picture and text digitizer paper feed mechanism, comprise optical imaging system, the CCD/CMOS assembly, the paper feed pallet, the paper delivery pallet, guidance panel, it is characterized in that paper feed pallet place is connected with the ADF automatic paper feeder, is provided with position transducer in casing, when the CCD/CMOS of imaging system assembly power supply, after the startup, set the switch of paper web on the push panel, paper is got in the action of ADF document feeder, Volume paper, paper feed, paper is to position transducer, position transducer sends signal to data processing module, the data processing module output signal, and camera lens is opened, take pictures, the shooting action is finished, the data processing module output signal, the work of ADF paper delivery device, printing paper enters the paper delivery pallet; Described position transducer can be an optoelectronic switch, can be mechanical type position travel switch; The position transducer installation position can be by A3, A4, the different big small breadth settings of B5, and the switch on guidance panel is set, set result's contact point signal, deliver to data processing module,, start camera and relevant position transducer by the signal of data processing module.

Advantage of the present utility model is, keeping the ZL200720093864.8 clear picture, storing under the situation of flexible advantage, increased ADF autofeed mechanism, give full play to the advantage of picture and text digitizer fast imaging, cost is low in addition again, be the strong competitor of high speed scanner, advantageous substitute.This picture and text numeralization collecting device, for the foundation of digital library, popularization, a kind of good instrument that provides is provided, it is institute's tanka volume of museum, exhibition hall's class, the collection of allusion quotation volume, a kind of good instrument that duplicates, it can become the quick means of information, information gathering, simultaneously, the technological progress for bibliogony, newpapers and periodicals, magazine printing industry has good impetus, this product has good market prospects.
