An image reading device includes a reading unit configured to read an image of a medium conveyed in a conveyance direction through a conveyance path, and a cleaning unit configured to clean a cleaning object in the conveyance path with an airflow. The cleaning unit includes a foreign matter moving unit configured to cause an airflow to flow in the conveyance path in a direction from one end to the other end that intersects the conveyance direction to move a foreign matter located at the cleaning object from the one end to the other end, and a first storage unit located at the other end of the conveyance path and configured to receive and store the foreign matter moved by the airflow in the direction from the one end to the other end.

A method of cleaning a tape and reel carrier tape by unspooling a tape and reel carrier tape from a first reel and onto a second reel. As the tape and reel carrier tape travels from the first reel to the second reel, the method includes passing the tape and reel carrier tape through an inner chamber of a contaminant removal apparatus, and removing contaminants from the tape and reel carrier tape by circulating air within an inner chamber of the contaminant removal apparatus.

A dust removal device capable of normally dedusting a surface of a sheet-shaped object having an edge portion of a shape with protruding parts continuously arranged at predetermined intervals along the longitudinal direction, that is, a dust removal device discharging a gas to a surface of a sheet-shaped object 100 from a discharge outlet while drawing in the gas above the surface of the sheet-shaped object 100 through a suction inlet, the discharge outlet including a first discharge outlet 30 for discharging the gas to portions of the sheet-shaped object 100 other than the edge portion and a second discharge outlet 35 for discharging the gas to the edge portion 100b of the sheet-shaped object 10, and the suction inlet including a first suction inlet (31, 32) for drawing in the gas above the surface of the portions of the sheet-shaped object 100 other than the edge portion 100b and a second suction inlet (33, 34) for drawing in the gas of the surface of the edge portion 100b of the sheet-shaped object 100.

A vacuum system is provided for cleaning an object (e.g., web and sheet cleaning). The system includes an air manifold with an inlet flange configured to receive contaminants and air. One or more shutters can be mounted to the inlet flange and arranged to adjust a size of an air inlet of the inlet flange. This is accomplished by arranging one or more shutters at one or more locations along the length of the inlet flange. Thus, a position of the shutters along the inlet regulates airflow into the air manifold, thereby providing a desired amount of exhaust at a desired location along the inlet. In operation, the air manifold is configured to draw air through the intake flange.

A vacuum system is provided for cleaning an object. The system includes an air manifold with a damper coupling attached a given end. The damper coupling is arranged within one of a plurality of outlets, the damper coupling receives a damper. Thus, a position and/or orientation of the damper may be adjusted by the damper coupling within the various outlets. In operation, the air manifold is configured to draw air from an intake flange, removing dust and air from the object being cleaned, which is exhausted to a vacuum system via the one or more outlets and dampers.

Provided is a coating film removing equipment that is a device including: a cleaning tank; a supply device configured to supply a cleaning liquid to the cleaning tank; a conveyance device configured to convey a coated film in a longitudinal direction of the coated film such that the coated film passes through the cleaning tank; a suction box that is disposed in the cleaning tank and surrounds a part of a conveyance path of the coated film with a gap through which a film can pass; a removing mechanism disposed in the suction box, the removing mechanism being configured to remove a coating film from the coated film; and a discharge device for discharging the cleaning liquid and the removed coating film from the suction box to an outside of the cleaning tank.
