Since a banknote quality inspection machine handles a large volume of cash, it is used in an environment that is always monitored and that cannot be entered or exited freely. For this reason, it is a device that is rarely seen by the general public. However, it needs to have a good design and to achieve the highest levels of inspection performance, reducing the stress of the operator’s environment as it is used for the inspection and bundling of banknotes. Toshiba’s goal with this unit was to provide a design that would satisfy the device’s professional operators, enabling ease of use, ease of maintenance, and stress-free use.
