Description
Technical Field
The present invention relates to a paper processing apparatus, and more particularly, to a paper processing apparatus having a platen.
Background
In modern offices, printing devices are indispensable tools, and include photocopiers, printers, scanners, office machines, and the like, among which the printer is most commonly used. Generally, a printer is connected to a computer, and a user can print an electronic document on the computer on blank paper through the printer. In order to facilitate sorting and filing, a user only needs to take out and align the printed paper sheets and bind the printed paper sheets into a book, so that the paper sheets can be prevented from being scattered in various places in a messy manner. For the user, the printer must wait for the printing operation before manually performing the binding procedure, and because the amount of data of the electronic document to be printed is different, the waiting time of the user is different, which brings about considerable trouble to the user. In view of the above, a paper processing apparatus with a binding function is proposed to solve the above problems.
A known paper processing apparatus has a paper placing platform for placing a plurality of pages of documents output from a printer or a scanner. The paper processing device performs operations such as arraying, binding and punching of a plurality of pages of documents on the paper placing platform, and then discharges the plurality of pages of documents to be positioned outside the office machine for a user to take. The multi-page documents may warp or fold in the process of falling into the paper placing platform, so that if the multi-page documents fall into the paper placing platform in sequence, the multi-page documents are affected by the documents already placed on the paper placing platform and are not orderly stacked, and the paper processing device is provided with the paper pressing device for pressing the multi-page documents flat when the multi-page documents fall into the paper placing platform, so that the multi-page documents on the paper placing platform are orderly stacked.
In the known paper processing device, the paper pressing device usually presses down the multiple pages of documents on the paper platform by the weight of the element, but if the documents with higher rigidity or higher curling degree are encountered by the gravity method, the curled documents can not be smoothly pressed, and the subsequent binding operation of the documents is directly influenced. Therefore, how to improve the above problems is the focus of attention of those skilled in the art.
