The bill printing machine comprises a detecting mechanism; the detecting mechanism comprises a first conveying roller, a second conveying roller, a first ejector rod, a second ejector rod and a circuit; the first ejector rod is elastically mounted on the side surface of the first conveying roller;the second ejector rod is elastically mounted on the side surface of the first conveying roller; the end, far from the first conveying roller, of the first ejector rod can be contacted with the end,far from the second conveying roller, of the second ejector rod; the diameters of the first printing roller, the second printing roller, the first conveying roller and the second conveying roller areconsistent; an indicating lamp is arranged in the circuit; an electric conducting first connecting block is arranged at the end, far from the first conveying roller, of the first ejector rod; an electric conducting second connecting block is arranged at the end, far from the second conveying roller, of the second ejector rod; and the first connecting block can be contacted with the second connecting block. The bill printing machine can perform punching positioning on multiple layers of bills before merging to improve the bill processing precision.

Description

technical field [0001] The invention belongs to the field of printing, and in particular relates to a bill printing machine. Background technique [0002] Invoices and other bills are business vouchers issued and received by units and individuals commonly used in our daily life when buying and selling goods, providing or receiving services, and engaging in other business activities. The invoice has continuity and uniqueness. Invoice printing is a rigorous and high-tech work. In general invoice processing, it is necessary to punch holes on the edge of the invoice. The punched invoice is easy to place when in use. In small printers, the printer can position the holes on the invoice, and it can be loaded in a stack on the receipt printer and continuously fed for uninterrupted printing. [0003] When making multi-layer invoices, the punching operation is generally performed after stacking several layers of invoices, and then uniformly punch holes. When the position is adjusted...

Problems solved by technology

[0003] When making multi-layer invoices, the punching operation is generally performed after stacking several layers of invoices, and then uniformly punch holes. When the position is adjusted and combined holes are processed, the position of the invoice after punching can no longer be adjusted, which reduces the processing quality and precision of the entire invoice, and the holes on each invoice cannot be adjusted during the printing process of the invoice. play a positioning role
