Description
- This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 98119361 filed in Taiwan, R.O.C. on Jun. 10, 2009, the entire contents of which are hereby incorporated by reference.
- The present invention relates to a supporting plate, and more particularly to a supporting plate for an automatic document feeder and a paper output mechanism using the supporting plate.
- Accompanying the progress of technology, business machines corresponding to computer peripherals such as printers, scanners, facsimile machines have proved so useful in increasing information processing efficiency, that they have become extremely popular. Furthermore, accompanying the technological development of one machine with multiple function, more and more business machines are provided with functions such as facsimile, scanning, photo-offset and printing; not only ensuring that the business machines have the capability to process multiple document types, but allowing the volume of such machines to be reduced. In addition, the assembly procedures thereof are simple, connecting them with a telephone line, a network cable and power cord, and they can then be used by collocating with a computer, all of which contributes positively to their popularity.
- A comprehensive survey of business machines such as printers, photocopiers, scanners and facsimile machines reveals that they are all equipped with an automatic document feeder (ADF) into which paper can be fed sheet by sheet. When a double faced scan or photocopy is processed, the conventional automatic document feeder drives a motor which rotates causing paper to reverse direction and be pulled back after the scanning or photocopy of the first face of the paper is completed, and the scanning or photocopy operation procedures of the second face thereof are then processed. When a double faced scan or photocopy of multiple sheets of paper is carried out, paper will be output onto a paper output tray along the supporting plate of the conventional automatic document feeder after the operation procedures of the first paper are completed. Thereafter, the scanning or photocopy operation procedures of the second paper are carried out.
- However, when the motor is driven so that it rotates, cause the paper to reverse direction and be pulled back, the action can easily cause the previous output paper to be pulled back together with the current sheet, causing the paper to be stuck such that the scan or photocopy cannot continue.
- To improve a paper output mechanism for an automatic document feeder and prevent pull-back happening after paper is output, the present invention is proposed. The present invention proposes a supporting plate for an automatic document feeder, installed with a plurality of paper feeding rollers corresponding to a plurality of transmission wheels, adapted to deliver documents to a paper output tray, where the supporting plate includes: a plate body, including a plurality of accepting holes used for accepting a plurality of paper feeding rollers, where the plurality of paper feeding rollers and the plurality of transmission wheel drive documents to move along a paper output direction toward the paper output tray, and a plurality of supporting portions, disposed on sides of the plurality of accepting holes along the paper output direction and used for supporting the document, ensures that each document forms a curved body while being moved.
- The present invention also proposes a paper output mechanism for an automatic document feeder, including: a paper output tray; a plurality of transmission wheels; a plurality of paper feeding rollers disposed correspondingly to the plurality of transmission wheels; a plate body, including a plurality of accepting holes used for accepting a plurality of paper feeding rollers, where the plurality of paper feeding rollers and the plurality of transmission wheels drive documents to move along a paper output direction toward the paper output tray, and a plurality of supporting portions, disposed on sides of the plurality of accepting holes along the paper output direction and used for supporting the document, ensuring that each document forms a curved body while being moved.
- Accordingly, the top end of the supporting portion is higher than the top end of the paper feeding roller; furthermore, the supporting portion includes a first end and a second end corresponding to each other, and the height of the second end is higher than the height of the first end.
- The present invention disposes the plurality of supporting portions arranged distantly on the plate body, and forms a supported document to be a curved body while being output so that the output document becomes stiffer in order to cause the document to drop at a place of the paper output tray further away from the plate body while being output; this not only prevents output documents from being stacked together on the paper output tray in a disorderly manner, but also solves the problem of the pull-back of the output paper found in a conventional paper output mechanism.
- The present invention can be more fully understood by reference to the following description and accompanying drawings, in which:
-
FIG. 1 is a schematic view, showing an outlook of a first preferred embodiment according to the present invention; -
FIG. 2 is a partly enlarged view, showing a portion A inFIG. 1 ; -
