Therefore, the present invention will be described in detail with reference to FIGS. 1-5.

First, Figures 1 and 2 will be described in Figure 1 is a schematic diagram of the present invention for counting the number of bills, showing the structure of a portable counter and a table counter, Figure 2 is a sensing rod needle 4 and the cartridge (18) ) Is a partial enlarged cross-sectional view of the state in which the sensing rod needle 4 is cut to form the step 17 to suppress sliding friction sound and to increase the fall impact amount when a drop impact sound is generated. In the upper portion, a connection port 7 for transmitting the impact sound low frequency signal to the table counter is provided. Secondly, referring to FIG. 3, FIG. 3 is an operation state diagram when counting the number of pieces of paper. The upper edge of the stack of bills spread out in a fan shape forms the step 17 of the sensing needle needle 4 of the sensing needle needle 4 Move the handheld counter to the inclined side while pressing it in the opposite direction of travel.

At this time, the sensing rod needle 4 proceeds while sliding on the banknote surface, and when falling by the thickness, a drop impact sound coming into contact with the bill is generated and the portable counter increases the coefficient by one each time the drop impact sound is generated by the first display panel unit ( 5) or to transmit the low-frequency shock sound signal to the table counter through the first wire connector (8).
