Abstract: A paper processing device includes a casing and a paper pressing mechanism. The casing includes a paper placement platform. The paper placement platform is extended externally from the casing so as to support the plural papers. The paper pressing mechanism includes a pressing bar, a driving mechanism and a linking mechanism. The pressing bar includes a pressing structure. The linking mechanism is connected between the driving mechanism and the pressing bar. While the linking mechanism is driven by the driving mechanism, the pressing bar is moved with the linking mechanism and rotated relative to the paper placement platform, so that the pressing structure is moved from an initial position to a target position. When the pressing structure is moved to the target position and contacted with the plural papers, a guiding channel is defined between the pressing structure and the paper placement platform.

Abstract: A printing device includes a sheet placement plate, an ejection roller module and an ejection control module. The ejection roller module is located near the sheet placement plate to eject at least one paper sheet. The ejection control module is connected with the ejection roller module. The ejection roller module is selectively in a released state or an ejection state under control of the ejection control module. When the ejection roller module is in the released state, the at least one paper sheet is transferred to the sheet placement plate through the ejection roller module. The ejection roller module is in the ejection state, the at least one paper sheet is outputted by the ejection roller module.

Abstract: A paper processing device includes a casing, a transfer roller assembly and a paper pressing mechanism. The casing includes a paper placement platform. The plural papers from a printing device are transferred to the paper placement platform by the transfer roller assembly. The paper pressing mechanism is located under the casing. The paper pressing mechanism includes a support frame, a pressing bar, a driving mechanism and a linking mechanism. The pressing bar includes a protrusion block. The protrusion block is penetrated through an opening of the casing. The protrusion block and the paper placement platform face each other. The linking mechanism is connected between the driving mechanism and the pressing bar. While the linking mechanism is driven by the driving mechanism, the pressing bar is moved linearly relative to the support frame, and the protrusion block is moved from an initial position to a target position.
