摘要： A ribbon protector is attached to a ribbon cartridge to prevent an ink ribbon from being soiled. The ribbon protector includes mounting portions, a protecting portion, and a paper guide. The ribbon protector is mounted to the ribbon cartridge by means of the mounting portions. The protecting section opposes an ink ribbon such that the ink ribbon is between the protecting section and the ribbon cartridge when the mounting portions have been mounted to the ribbon cartridge. The paper guide projects from the protecting section to incline toward the ribbon cartridge. The mounting portion may have a first base portion continuous to the protector and the paper guide has a second base portion continuous to the protecting section. The first base portion is thicker than other portions of the first projecting portion and the second base portion is thicker than other portions of the mounting portion.

摘要： Washer media are disposed in an air inlet and an air outlet of a water spray chamber. A basic unit is formed by first stage nozzles from which spraying water that reaches the inlet washer media is sprayed in the reverse direction to an air flow; a water storage tank for receiving spraying water, located in the lower position of the water spray chamber; and a circulating water supply system that circulates the circulating water in the water storage tank to the first stage nozzles. Second stage nozzles from which spraying water directed against the outlet washer media is sprayed in the forward direction to the air flow are disposed in approximately the same positions as the first stage nozzles. There is also provided a supplementary water supply system for supplying supplementary water to the second stage nozzles.
