Paper-blocking assembly and paper processing device using the same

A paper-blocking assembly for a paper processing device, comprising:

• a paper holder for holding paper;
• a shaft;
• a restriction portion disposed on the shaft, when the shaft rotating, the restriction portion moving between a first position and a second position and the shaft driving a paper feeding portion of the paper processing device;
• and
• a paper blocking portion comprising a paper blocking plate, the paper blocking portion rotatorily coupling to the paper processing device;
• wherein when the restriction portion is in the first position, the restriction portion abuts the paper blocking plate to make the paper blocking plate in a paper blocking position, and when the restriction portion is in the second position, the restriction portion is away from the paper blocking plate to cause the paper blocking plate in a paper feeding position and the paper feeding portion feeds the paper.
