Description of the Invention: [Technical Field] The present invention provides a cam link paper blocking mechanism, and more particularly to a paper bar blocking mechanism for a transaction machine. [Prior Art] Even though the technology of communication-related industries is highly developed, although the concept of paperless operation is common, the transmission of information is inevitably required to be expressed through paper. After all, paper still has many irreplaceable Advantages, such as easy to carry and easy to modify and circulate. In general, the transaction machine has the function of printing. However, in the trend of communication products, the multi-function machine with scanning, printing, faxing and copying functions has been derived. Widely used in various fields of society, such as corporate companies, government agencies, academic institutions and even individuals, multi-function machines can meet the needs of processing large amounts of information and having to use a large amount of paper. However, in the printing work of a large amount of paper, how to keep the paper feeding process smooth without causing paper jam is one of the problems that the multifunction machine needs to overcome.
