Beschreibung
Zusammenfassung:	A paper-type detection device (1) comprises a sensor unit (10), a storage unit (20) and a control unit (30). The sensor unit (10) is used for detecting a transmission state of a paper (100) according to a fixed clock period, and carrying out binaryzation on detected signals to indicate the presence-absence state of the paper (100). The storage unit (20) is used for acquiring the signals detected by the sensor unit (10), acquiring paper (100) information in the signals, and storing the paper (100) information in sequence. The control unit (30) comprises a first state counter and a second state counter. The control unit (30) controls the two state counters for carrying out zero clearing and starting operations for counting in conjunction with the sensor unit (10), in order to eliminate the interference in a predetermined threshold value, so as to eliminate the interference brought by the paper (100) in a poor state and make sure that the information recording sequence of paper (100) is consistent with the transmission sequence of the paper (100). Also disclosed is a paper-type detection method.
