    摘要: A drive transmission mechanism of a sheet transportation apparatus of the present invention comprises an upstream transportation roller gear and a planet gear for transmitting a first driving force from a driving source to the upstream transportation roller gear, and a release mechanism for preventing the upstream transportation roller gear and the planet gear from engaging with each other. The release mechanism prevents the engagement of the planet gear and the upstream transportation roller gear when the driven gear is driven to reversely rotate by a second driving force. The release mechanism prevents the engagement by moving a release member before the planet gear and the driven gear engage with each other. The release mechanism moves the release member by the driven gear being reversely rotated by the second driving force which is a driving force other than the driving source. This makes it possible to realize a drive transmission mechanism of a sheet transportation apparatus comprising a release mechanism capable of releasing the engagement of the driven gear and the drive gear for transmitting the driving force from the driving source to the driven gear, without the need of reversely rotating the driving source or the fear of impairing the driving force from the driving source.

    摘要: ADF includes a pickup roller, an arm, a regulatory member, a drive motor and a control section. The pickup roller is supported at shaft thereof by the arm swung between a lowered position and a raised position. The drive motor supplies a driving force for the swing to the arm. The regulatory member constrains the arm from moving upward across the raised position. The control section sets a setting-speed of the drive motor to a first speed by which much importance is attached to the reduction of driving noise of the drive motor when a first driving factor causing the arm to move from the neighborhood of the raised position occurs, and sets the setting-speed to a second speed by which much importance is attached to the reduction of contact noise with the regulatory member when a second driving factor causing the arm to move from the lowered position occurs.
