Cheque processing device

1. A cheque processing device, comprising:

a base,

a frame located at the top face of the base and forming a U-shaped paper passage, and

multiple sets of conveying roller assemblies and multiple processing mechanisms provided along the U-shaped paper passage,

wherein one end of the U-shaped paper passage is an inlet and the other end is an outlet,

wherein the frame comprises a fixed frame body, and a first movable frame body and a second movable frame body which are on the outside of the fixed frame body, only the first movable frame body and the second movable frame body forming the U-shaped paper passage together with the fixed frame body, the first movable frame body and the second movable frame body being directly pivotable on the base to open and close with respect to the fixed frame body,

wherein at least some of the multiple sets of conveying roller assemblies and the multiple processing mechanisms are in an exposed state when the first movable frame body and/or the second movable frame body is/are opened with respect to the fixed frame body,

wherein the first movable frame body is approximately L-shaped as a whole when seen from above and extends along a first side and a second side of the fixed frame body, and the second movable frame body is approximately I-shaped as a whole when seen from above and extends along a third side of the fixed frame body, wherein the first side, the second side and the third side of the fixed frame body are connected end to end orderly and U-shaped,

wherein a straight channel of the U-shaped paper passage is formed between the second movable frame body and the fixed frame body,

wherein when the first movable frame body and the second movable frame body are closed with respect to the fixed frame body, the first movable frame body and the second movable frame body are spaced apart by a set distance to form a straight inlet paper passage there between, and

wherein the straight inlet paper passage merges with the straight channel of the U-shaped paper passage.

2. The cheque processing device according to claim 1 , wherein the pivoting position of the first movable frame body is close to the inlet of the U-shaped paper passage, and the pivoting position of the second movable frame body is close to the inlet of the straight channel.

3. The cheque processing device according to claim 1 , wherein a scanning mechanism is provided in the straight channel, and the scanning mechanism comprises a first scanning module configured to scan an image on a first face of a cheque and a second scanning module configured to scan an image on a second face of the cheque.

4. The cheque processing device according to claim 1 , wherein a reading magnetic mechanism and a printing mechanism are provided between the inlet of the U-shaped paper passage and the straight channel orderly.

5. The cheque processing device according to claim 1 , wherein the processing mechanisms and the conveying roller assemblies located at the first side and/or the second side of the fixed frame body are all provided on the fixed frame body and/or the base.

6. The cheque processing device according to claim 1 , further comprising a paper pick-up mechanism provided at the inlet of the U-shaped paper passage, wherein the paper pick-up mechanism comprises a paper-fetching roller, a movable platen, and an elastic element configured to bias the platen to the paper-fetching roller.

7. The cheque processing device according to claim 6 , further comprising a paper-separating mechanism located downstream of the paper pick-up mechanism, wherein the paper-separating mechanism comprises a paper-separating roller and a paper-pressing member.

8. The cheque processing device according to claim 1 , further comprising a third frame body forming an accommodating groove between the outlet of the U-shaped paper passage and the fixed frame body, wherein a stop lever is provided at a gap of the accommodating groove.
