Abstract: A sheet conveying apparatus includes a conveying mechanism and a control unit. The conveying mechanism is configured to pick up and convey a sheet every first time interval T and includes a sound source which produces a plurality of element sounds attendant on conveying the sheet. The control unit is configured to control the conveying mechanism so that the element sounds are caused at times determined based on a second time interval. The second time interval is acquired by dividing the first time interval T by a division number n which is an integer of two or more.

Abstract: A sheet conveyance device includes: a first conveyance member configured to convey a sheet in a first direction; a second conveyance member configured to convey the sheet in a second direction; a guide disposed between the first conveyance member and the second conveyance member, the guide having a curved face configured to guide the sheet conveyed from the first conveyance member to the second conveyance member; and an adjustment member disposed at an inner position of the curvature of the curved face of the guide, the adjustment member being configured to swing to contact with a curved inner face of the sheet guided by the guide in accordance with a contact force applied by the sheet.

Abstract: In a sheet conveying mechanism, a first bulging space and a second bulging space are provided on a downstream side and an upstream side, respectively, of a conveying path. The second bulging space has a length L1 along the conveying path. The conveying path between the first and second bunging spaces is defined to have a length L2. The lengths L1 and L2 are set to satisfy a predetermined relationship with a frequency of noise propagating through the conveying path. The sheet conveying mechanism can inexpensively reduce noise generated inside the conveying path during sheet conveyance without hindering the conveyance of the sheet.
