Diagnosis data for respective portions of an apparatus are collected from respective sensors provided on the apparatus at the respective portions thereof and stored in a memory for each of the respective portions. These diagnosis data are the amount of change with time and frequency of occurrence of abnormal operation. The amount of change with time is yielded from the number of treatments for a detection object of each sensor, while the frequency of occurrence of abnormal operations is provided as a ratio of the number of anbormal operations detected by the respective sensors to the number of treatments by the particular object or part involved. The resulting diagnosis data is compared with a predetermined reference value, and when the diagnosis data exceeds the reference value, a prediction alarm flag indicative of a prediction of necessary maintencance to prevent trouble from occuring is added to the diagnosis data and stored in the memory.

Self-diagnosis method for a bank note depositing and dispensing machine

An automatic money depositing apparatus includes a customer access panel having a receiver slot for receiving moneys deposited by a customer and a return slot for returning moneys deposited by the customer; a separator/feeder for separating and feeding the moneys one by one which have been received through the receiver slot; a discriminator for checking whether the moneys fed by the separator/feeder are true or false and identifying the demoninations of the moneys; wherein the separator/feeder and the discriminator are disposed behind the customer access panel. A temporary storage unit for temporarily storing true and false moneys separately is located adjacent to the return slot. A money container stores the true moneys delivered from the temporary storage unit. Input keys are operated by the customer to indicate approval or nonapproval of a money deposit made by the customer through the receiver slot. A control unit is responsive to operation of the input keys indicative of a nonapproval of the money deposit for opening the return slot to allow the customer to remove the moneys directly from the temporary storage unit. When trouble occurs prior to operation of the input keys, the receiver and return slots are opened to give the customer access to the moneys in the apparatus. The return slot is openable to different degrees dependent on whether only the false moneys or all of the deposited moneys are to be removed from the temporary storage unit.
