Abstract
A sheet conveying device includes a primary sheet guide including a bending portion to bend a sheet while the sheet slides over the bending portion to change a sheet conveyance direction and a secondary sheet guide disposed opposite the primary sheet guide with an interval between the primary sheet guide and the secondary sheet guide. A noise attenuator intakes and attenuates slide noise generated by the bending portion while the sheet slides over the bending portion. The noise attenuator includes a resonant cavity disposed opposite an outer face of one of the primary sheet guide and the secondary sheet guide. A sound inlet is disposed in proximity to the bending portion and intakes the slide noise generated by the bending portion. A sound guide communicates with the sound inlet and the resonant cavity to guide the slide noise from the sound inlet to the resonant cavity.
