Feature of the present utility model is that also the described micro computer main circuit board that includes microprocessor, storer, clock circuit and each interface circuit is fixed on the hull outside intralamellar part, and its digital demonstration and keyboard are fixed on housing interior plate outside.

The utility model shows by the counting circuit of the counting part number to putting banknote, and exports corresponding count signal by this counting circuit, through counting interface circuit, exports microcomputer circuit to.Under the control of set working routine, by operation keyboard, can finish various settlement function, and show with number by microcomputer circuit, such as show the amount of money number of meter banknote number correspondence; Show the bale of the other banknote of various volumes, number and folded number; Carrying out the branch family handles; Show the amount that has received; Show all amount of money values that received each user; Show the amount of money value that every user receives respectively; Finish the manual amendment and manually search.Described various demonstration all can be by printer interface by printer prints, and connects with microcomputer.

The utlity model has following advantage.

1, the utility model organically combines paper money counter of the prior art and microcomputer circuit by each interface circuit, thereby can finish various clearing work in counting.Use the utility model, can simplify Bank Clerk personnel's working routine greatly, alleviate its labour intensity.

2, the utility model is in the counting circuit of its counting part, adopt integrated component, adopt the paper money counter counting circuit of discrete component compared to prior art, the element number reduces to about ten from about 45, not only on circuit structure, simplify greatly, and its functional reliability is improved.

3, the utility model makes it have remote communications capability owing to adopt level shifting circuit in microcomputer interface circuit.

4, the utility model keeps the contour structures of paper money counter in the prior art, only sets up operation keyboard and digital the demonstration in its housing interior plate outside.The whole instrument profile is simple, and the inner structure compactness is easy to use flexible.
