Cause estimation device, cause estimation output method and paper leaf handling system

摘要

The cause estimation device (3) includes a collection unit (21A), a learning unit (21B), and an estimation unit (21C). The collecting unit collects state data for each unit in the ATM (2) that handles banknotes. The learning unit generates a learning model for estimating the cause related to the error or the error sign for each unit with respect to the error or the error sign of the ATM based on the state data. When an error or an error sign is detected from the state data, the estimation unit estimates the cause for each unit based on the learning model, and notifies the management device (4) of the cause that is the estimation result. When the management device receives the cause from the cause estimation device, the management device notifies the worker terminal (6) and the maintenance company terminal (5) of the recovery procedure corresponding to the cause. It is possible to prevent the ATM service from deteriorating due to the extension of the restoration period.
