AI Technical Summary
Technical Problem
Existing document conveying devices suffer from abnormal noise generation due to paper dust rubbing against the separation roller or separation pad when paper dust is caught between them during non-sandwiched periods.
Method used
The sheet transport device incorporates a separation pad with higher hardness than the separation roller, knurled for improved grip, and vibration damping members to suppress vibrations and noise.
Benefits of technology
This configuration effectively reduces abnormal noise by minimizing vibrations between the separation roller and pad, ensuring smooth operation and preventing double feeding.

Abstract
The purpose is to suppress abnormal noises caused by paper dust being rubbed against the separation rollers and separation pads. [Solution] The sheet transport device comprises a feed roller that feeds sheets from a paper tray in a predetermined transport direction Z, a separation pad 48 provided downstream of the feed roller in the transport direction Z, a separation pad holder 50 that holds the separation pad 48, a transport guide member 39A that guides the transport of the sheets and supports the separation pad holder 50, a separation roller that holds the sheets fed by the feed roller between itself and the separation pad 48 and transports them in the transport direction Z, a first vibration damping member 61 provided between the separation pad 48 and the separation pad holder 50, and a second vibration damping member 62 provided between the separation pad holder 50 and the transport guide member 39A.
