A medium conveying apparatus includes a housing in which a paper feeding port is provided, a paper feeding roller configured to convey paper through the paper feeding port, a drive shaft to which the paper feeding roller is attached, the drive shaft extending in a Y direction intersecting a conveying direction of the paper, and an elastic roller attached to the drive shaft and configured to prevent sound occurring on the inside of the housing from leaking to the outside of the housing through the paper feeding port. The elastic roller comes into contact with the paper conveyed by the paper feeding roller and removes electric charges of the paper.

A paper feed apparatus includes a paper feeding roller and a separating pad for separating paper one by one and feeding the paper. This separating pad is supported by a separating pad holder to be abutted onto the paper feeding roller with a predetermined pressure. Furthermore, the separating pad holder is provided with a weight member in a loosely-fitted state.

An adhesive tape dispenser (1) includes a handle (2), a receiving apparatus (33) with a bearing (3) for an adhesive tape roll (100), an application apparatus (38) with an application roller (4), and a rotation-resistant fixed friction bridge (5) with a bridge sliding surface (6) and a deflection bead (26), wherein the adhesive tape dispenser (1) is adapted and arranged such that, during unwinding, an adhesive tape portion (103) of an adhesive tape roll (100) present on the bearing slides or is slidable over the bridge sliding surface (6), before the adhesive tape portion meets the application apparatus (38).

A sheet conveying device includes a conveyor, a sound collector, an operation unit, and circuitry. The conveyor conveys a sheet in a sheet conveyance direction. The sound collector collects sound produced by conveying the sheet by the conveyor. The operation unit outputs information of a conveyance of the sheet. The circuitry is to cause the sound collector to collect the sound, detect a factor of an abnormal conveyance produced by conveying the sheet based on the sound collected by the sound collector, locate a position of the factor of the abnormal conveyance of the sheet in response to a detection of the factor of the abnormal conveyance of the sheet, and output, to the operation unit, the position of the factor of the abnormal conveyance of the sheet.

Sheet media jams are detected along a media transport path by one or more vibration sensors that capture mechanical movements of components along the path that interact with the sheet media for driving or guiding the sheet media along the transport path. The detected vibrations during the advancing of the sheets are analyzed for distinguishing between detected vibrations associated with normal handling of the sheets and detected vibrations associated with abnormal handling of the sheets. An error condition can be signaled to a control system in response to distinguishing the detected vibrations associated with the abnormal handling of the sheets.

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.

A medium discharge unit that discharges a medium subjected to recording by a recording unit, a placement unit at which the medium discharged by the medium discharge unit is placed, the placement unit being inclined with a downstream side in a discharge direction in which the medium is discharged being positioned, in a vertical direction, above an upstream side in the discharge direction, an air blowing unit that blows air from above toward the medium discharged from the medium discharge unit, and a control unit that controls the air blowing unit are included. The control unit can attenuate air blowing by the air blowing unit, based on information of an interval between a preceding medium and a following medium that are to be discharged from a discharge position of the medium discharge unit to the placement unit, when the preceding medium is discharged from the discharge position.
