PURPOSE:To detect correctly the number of banknotes in an automatic cash dispenser by inputting at least one reference signal to a detecting means in place of the output signal from a thickness detecting sensor and testing the operation thereof. CONSTITUTION:A CPU11 feeds first a control signal C1 to operate a relay 151 which inputs a high level reference voltage V to a thickness detecting circuit 13. The circuit is decided to be normal if an output signal S1 is a 1 level in this stage. If the circuit is normal, a control signal C2 is fed to operate a relay 152 which inputs a low level reference voltage V to the circuit 13. The circuit is decided to be normal if an output signal S2 is a 1 level in this stage. If the circuit is normal, a control signal C3 is fed to operate a relay 153 which inputs the output signal from a sensor 18 to the circuit 13 to execute ordinary thickness detection. The circuit 13 feeds the results of the respective signals via a latching circuit 19 to the CPU11. |
