Abstract
A medium-suction apparatus includes a conveyer to convey a medium in a conveyance direction, a first suction unit to perform suction operation on the medium to attract the medium to the conveyer, and a second suction unit to perform the suction operation on the medium to attract the medium to the conveyer. The second suction unit being disposed next to the first suction unit in a width direction perpendicular to the conveyance direction. The second suction unit starts the suction operation after the first suction unit starts the suction operation.
Claims19
A medium-suction apparatus comprising:
- a conveyer to convey a medium in a predetermined conveyance direction;
- a first suction unit to perform a first suction operation on the medium to attract the medium to the conveyer;
- a second suction unit to perform a second suction operation on the medium to attract the medium to the conveyer, the second suction unit being disposed next to the first suction unit in a width direction perpendicular to the conveyance direction;
- and
- a controller to control the first suction unit to start to perform the first suction operation on the medium at a first timing and to control the second suction unit to start to perform the second suction operation on the medium at a second timing, which is a predetermined amount of time, registered by the controller, after the first timing at which the first suction unit starts performing the first suction operation on the medium.
A medium-suction apparatus comprising:
