Abstract
In a blast mechanism for optimizing an air blast in the main scanning direction and an air blast in the sub-scanning direction so as not to affect reading accuracy of an image, a first blast path for sending air in the main scanning direction and a second blast path for sending air in the sub-scanning direction are formed inside the housing, and collection efficiencies of air filters of the blast paths are set so that the efficiency in the main scanning direction is high than that in the sub-scanning direction. The blast mechanism includes a casing, first and second blast paths in the main and sub-scanning directions disposed in the casing, and air filters disposed in the respective blast paths. The dust collection efficiencies of the air filters are set so that the filter of the first blast path is higher than the filter of the second blast path.
