Abstract
A scanning device on which an automatic paper supply machine can be arranged is disclosed. Light from at least one light source reflects from a plurality of glasses to one image receiving unit. The reflecting glass comprises at least one changeable reflecting glass which can switch between the two positions. One scans the first position of the manuscript in platform type and the other scans the second position of the manuscript in paper feeding type. When the scanner scans in paper feeding type, an image receiving unit adjusts the place to move in a certain displacement so that the total length of the optical path is adjusted and the route thereof is changed. The size, weight and cost of the scanner can be reduced effectively.
Description
The relevant a kind of scanister of the utility model, particularly a kind of scanister of installing automatic sheet feeder, it switches via a light path, can carry out the paper feed type scanning of platform-type scanning or automatic sheet feeder.
The principle of scanner mainly is to utilize optical devices, with light beam steering through lens imaging, and utilize a charge coupled cell (CCD converter) to convert the light signal of imaging to digital signal that the brain of can powering is handled, but because the light path of its imaging institute palpus has certain-length at least, if light path is a straight line, then may make the volume of optical path device become very big, but excessive volume and present electronic product are towards gently, thin, short, little trend is disagreed, therefore, the optical path device of current scanline device, generally be to utilize several pieces catoptrons under the constant principle of optical path length, the light that enters optical path device inside is done reflection for several times, the volume of scanner can effectively be reduced.Therefore, in optical path device, its number of mirrors, size and position corresponding mutually, configuration thereof will directly determine the volume and the weight of this optical path device, the also size of the overall weight of remote effect scanner and volume.
In the existing scanner, generally be to carry out individual scanning, when need carry out many scannings, then operation is more loaded down with trivial details, also more time-consuming, so can install an automatic sheet feeder additional in the existing scanner, so that paper feed type scanning to be provided, exempt personnel's stand-by period, can improve scan efficiency.
See also Figure 1A, it is the synoptic diagram of the optical devices of existing platform scanner device.Definition has one first scanning area 11 on the plat form type scanning apparatus 10, it is provided with platform-type mode and scans an original copy 40, plat form type scanning apparatus 10 includes: a light source 30, the original copy 40 that can provide the light directive to be positioned at scanning area 11 is to carry out platform-type scanning.
One first load bearing seat 60, which is provided with one first catoptron (M1), one second load bearing seat 70, which is provided with one second catoptron (M2) and one the 3rd catoptron (M3), light source 30 is combined on first load bearing seat 60, and with its interlock, first catoptron (M1), second catoptron (M2) and the 3rd catoptron (M3) can be accepted to penetrate the light that comes and with its reflection by original copy 20.When scanning in platform-type mode, first load bearing seat 60 and second load bearing seat 70 drive with a drive unit 50, move between first scanning area 11 with 2: 1 speed linearities.
An image pickup unit 80 can be accepted to reflect the light that comes, and be converted into electric signal corresponding to second load bearing seat 70.Wherein image pickup unit 80 includes: a camera lens 81 can receive the light that its reflection is transmitted, and be gathered in its focus place; And a charge coupled cell 82, be located at the focus place of camera lens 81, and can receive the light that camera lens 81 is assembled, convert the digital signal that the brain of can powering is handled to.
When scanning in platform-type mode, wherein the course of light by light source 30 through original copy 40, M1, M2, M3 to image pickup unit 80.
