Description
Technical field
The present invention relates to a kind of conveying-type scanning means, in particular to a kind of conveying-type scanning with the eliminating machine that trembles
Device.
Background technique
In traditional automatic sheet feeder, file is usually conveyed using idler wheel by scanning window, for being located at scanning
The scan module of beneath window scans the image of file.The scanning quality of document image and the depth of field of scan module are related.Scape
It is deep more big, allow to convey in file may not necessarily it is completely smooth in scanning window, the depth of field is smaller, do not allow to convey
In file far from scanning window.
When file passes through scanning window, is fallen in the field depth of scan module to effectively control file, there is one kind
Traditional scanner is using idler wheel come contact scanning window.When file not yet passes scanning window, idler wheel and scanning window
Sliding friction is done, when file passes through scanning window, idler wheel and file make rolling friction, and file makees sliding with scanning window and rubs
It wipes.In the case, the abrasion loss of idler wheel and the abrasion loss of scanning window are all quite big, are easy to influence scanning quality.Moreover, working as
When file thickness thickens, file may be not easily accessible among idler wheel and scanning window, and be unable to complete conveying program.Therefore, existing
There is technology for being usually as much as possible to push away file using elastic force in the depth of field of scan module by the document control in conveying
Toward scanning window.Whether file is suppressed using plate or idler wheel, since the contact area of plate and file is too big, all can not
Really make to be attached on scanning window completely by the file of scanning area.Especially the case where using contact type image sensing module
Under, scanning quality is easier to be affected, and traditional plate or idler wheel are also just unable to satisfy the demand of user.
Alternatively, some scanning windows be no glass and in hollow out state.At this point, with idler wheel generate friction component just at
For scan module.Therefore, existing way accelerates the abrasion of idler wheel and scanning window or scan module, and then influences subsequent
Image scanning quality.
Furthermore in the defeated scanners of the prior art, file is easy to collide transparent platform and output channel and generate
It trembles to influence scanning quality, and when the end of file is detached from comber and conveying roller, tremble (shock) can be generated,
Because scanning continues carrying out, image scanning quality can be further influenced.
Summary of the invention
Therefore, it is an object of the present invention to provide a kind of conveying-type scanning means with the eliminating machine that trembles, effectively
It solves the problems, such as to tremble brought.
In order to achieve the above object, the present invention provides a kind of conveying-type scanning means, comprising channel, conveying mechanism, compacting idler wheel,
Elastic slice and scan module.Conveying mechanism conveying original copy passes through channel.Compacting idler wheel and elastic slice are respectively arranged at the two sides in channel,
It suppresses idler wheel and suppresses original copy toward elastic slice.Scan module is set to the downstream of compacting idler wheel and elastic slice, and executes image to original copy
Scanning.
Therefore, a piece of elastic slice is arranged in conveying-type scanning means provided by the embodiment of the present invention in the channel, matches combined pressure
Idler wheel processed suppresses original copy, so that original copy not will receive (shock) influence of trembling, and scape when scan image during the scanning process
It is deep to maintain certain value, it is maintained scanning quality of the gained picture.
For above content of the invention can be clearer and more comprehensible, convenient embodiment is cited below particularly, and cooperate appended attached
Figure is described in detail below.
