Abstract
The invention discloses a paper separating device. The paper separating device comprises a paper feeding roller, a friction roller, a connecting piece and a buffer structure. The friction roller is arranged opposite to the paper feeding roller; a gap is formed between the friction roller and the paper feeding roller; and the paper feeding roller drives files to pass through the gap. The connecting piece has a first end and a second end; and the friction roller is mounted at the first end. The buffer structure is connected to the second end of the connecting piece, and comprises an elastic component and a damping, wherein the damping coats the elastic component. After the files are conveyed to pass through the gap, the friction roller is suffered from the resistance provided by the damping through the connecting piece to buffer the impact force on the paper feeding roller. The invention further provides a transaction machine, wherein the transaction machine comprises a main body and the paper separating device. The main body comprises a paper inlet and a casing; and the paper separating device is arranged in the paper inlet, and is connected with the casing.
