Both side edge parts in the other end part of the cleaning element are fixed to the outer peripheral surface of the roller. The both side edge parts in the other end part of the cleaning element are located on the outside of their region that is to face to possibly largest paper. | 02-05-2015 |
20150246557 | CONVEYOR DEVICE AND INKJET RECORDING DEVICE INCLUDING CONVEYOR DEVICE - A conveyor device is arranged to face a recording head. The conveyor device includes a conveyance belt and a suction section. The conveyance belt conveys a recording medium. The suction section includes a guide member that supports the recording medium through the conveyance belt. The suction section sucks the recording medium through a plurality of first holes passing through the guide member and a plurality of second holes passing through the conveyance belt to attach the recording medium to the conveyance belt. None of the first holes are formed in a first region of the guide member. The first region is a region where a partial region pertaining to a feeding member overlaps with a head facing region facing the recording head. | 09-03-2015 |
20150273876 | CONVEYOR DEVICE AND INKJET RECORDING APPARATUS - A conveyor device is installed opposite to a recording head in a recording apparatus. The conveyor device includes a conveyor belt and a suction section. The conveyor belt conveys a recording medium. The suction section includes a guide member having first through holes within a first region and second through holes outside of the first region. The guide member has a surface that is located opposite to the recording head with the conveyor belt therebetween and that has first grooves and second grooves therein. The first region includes at least a head facing region located directly opposite to the recording head. The first through holes are located inside of the first grooves. Each of the first grooves is shorter than the recording head. The second through holes are located inside of the second grooves. The suction section sucks on the recording medium through the conveyor belt and the guide member. | 10-01-2015 |
