<p>PURPOSE:To automatically clean an adhering stain to be removed by providing a pressure air injection port in the vicinity of a light detecting sensor. CONSTITUTION:A main unit provides in its inside light detecting sensor parts 16a to 16f detecting a note to pass through, injection ports 17a to 17f for injecting pressure air to a light detecting sensor in the vicinity of a position opposed facing to each sensor and a pressure air injection control mechanism part 17 for feeding pressure air to each injection port. In- or out-money transactions are started, when a motor part is turned on, the pressure air injection control mechanism part 17 operates, and generating air following rotation of a fan when it rotates, the fan generates the pressure air to be injected cleaning the light detecting sensor parts 16a to 16f along the pressure air injection ports 17a to 17f throttled in a nozzle shape.</p> |
