The invention provides a paper counting machine. According to the embodiment of the invention, the paper counting machine comprises: a roll-out portion, which is used for paper rolling out; a transmitting portion, which is used for transmitting a piece of paper from the roll-out portion; a data read-out portion for identification, which uses at least one sensor arranged at the transmission portion to read data for identification; an identification portion, which is used for identifying the paper based on the read data for identification; an accumulation portion, which is used for accumulating the paper transmitted by the transmitting portion; a driving portion, which is used for driving the roll-out portion and the transmitting portion; and a controlling portion, which is used for controlling the driving portion based on the identification data from the identification portion. Under the circumstances that a first piece of paper transmitted by the transmitting portion meets a specified requirement, when the first piece of paper is accumulated in the accumulation portion and at least one portion of a second piece of paper following the first piece of paper is kept in the transmitting portion, the controlling portion stops the driving portion; and after the driving portion is stopped, the controlling portion enables the driving portion to move again, thereby continuously carrying out paper counting processing.
