FIG. 19 is a flowchart showing a control procedure of deposit counting integration control (integration mode). As shown in this figure, in the deposit counting accumulation control, the lift motor 6 is driven in the second direction, the cam 7 (lift blade 411) is moved to the accumulation position (S1901), and then accumulation is started ( S1902). When the intermediate passage sensor 312 detects the leading edge of the banknote P (S1903), the butterfly solenoid 310 is turned on (S1905) after 175-step conveyance (S1904), and then the intermediate passage sensor 312 detects the trailing edge of the banknote P (S1906). ), The butterfly solenoid 310 is turned OFF (S1908) at the time of 35-step conveyance (S1907), and the stacking process of one bill is terminated (S1909). Thereafter, the counting process is executed (S1910), and the end of feeding is determined (S1911). If it is determined that the feeding is continued, it is determined whether or not the butterfly position sensor 308d is in the transmission state (S1912). If the butterfly position sensor 308d is in the transmissive state, the process directly returns to step S1903 to continue the accumulation process, but if the butterfly position sensor 308d is in the non-transmissive state, the lift motor 6 continues until the transmissive state is reached. Is lowered by a predetermined stroke (S1913), and the process returns to step S1903.

Is driven in the second direction, and while the cam 7 (lift blade 411) is moved to the return position (S2104), the feeding sensor 306 determines whether the banknote P is fed out (S2105). In this state, the lift motor 6 is driven upward (S2106) for a predetermined time (20 ms) while judging whether the detection signal of the feeding sensor 306 has changed within a predetermined time (20 ms), but the lift blade 411 is returned. If the feeding does not start even when the position is reached (S2107), the lifting motor 6 is moved to the lowest position (S2108), and then the feeding process is repeated up to twice (S2109). On the other hand, when the bill P starts to run out, the separation solenoid 311 is turned on (S2112) when the intermediate passage sensor 312 detects the leading edge of the fed bill P (S2110) and transports 15 steps (S2111). When the intermediate passage sensor 312 detects the trailing edge of the fed banknote P (S2113), the counting process is performed (S2114). Thereafter, it is determined whether or not the return count end recognition control is in the end recognition state (S2115). If the determination is YES (Yes), the return count processing end routine is executed (S2116) to end the return count feed-out control. To do. On the other hand, if the above determination is NO (No), the separation solenoid 311 is turned off (S2118) after 70-step conveyance (S2117), and the process returns to step S2105 to continue the return feeding process.
