File automatic entrance and exit device and method for double side scanning using the device

Abstract

The present invention relates to a device for document automatically entering and exiting and a method using the device to scan documents in two-sides; the device comprises an input tray, an exit tray, a scanning module, a first steering group, a second steering group, first to fourth paths, and an exit path. During double-sided scanning, documents can be sent to the scanning module through the first path to scan the first side; then the documents can be sent by the second path to the first steering group, and can be sent back to the first path consequently by the third path via the inversion of the first steering group, and can be scanned for second time by the scanning module; and then the documents can be sent to the second steering group along the fourth path, and next, under the help of the second steering group, the documents can be sent along the exit path to the first steering group, and then can be sent to the exit tray to finish the double-sided canning; via the paths and a first leading unit, the present invention can not cause repeated paths no matter how the documents are on the way of one-sided canning and double-sided canning, thereby avoiding paper blocking, solving the problem of ordering paper as well as shortening the canning path and time.

Description

technical field [0001] The present invention relates to a document automatic input / exit device and a method for using the device for double-sided scanning of documents, in particular to a document double-sided scanning applicable to a photocopier, which can shorten the document scanning path and The utility model relates to an automatic file in / out device capable of solving the problem of document page sorting, and a method for scanning documents on both sides by using the device. Background technique [0002] Please refer to FIG. 1, which is a schematic side view of a structure, which is a small-sized document input / output device 1 for an image forming device of US Patent No. 5,784,680, which includes a document placement tray 11, a scanning mold Group 12, a paper output tray 13 and a path switching element 14, and the path from the file placement tray 11 to the scanning module 12 is a first path 101, and the path from the scanning module 12 to the paper output tray 13 is a...

Problems solved by technology

[0009] However, the disadvantage of the automatic in / out device 2 of this document is that the separation of the driving side roller 25 from the central roller 23 must be done through an additional and more complicated gear mechanism. Or the transmission mechanism can be completed, resulting in complex structure and increased cost

[0010] It can be seen from this that the above-mentioned existing automatic file entry / exit device and the method for double-sided scanning of files obviously still have some disadvantages in terms of product structure, scanning method and use. Inconvenience and defects, and urgently need to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
