A medium conveying apparatus includes a plurality of feed rollers, each feed roller rotating independently at a respective speed to feed a medium, a first sensor located on a downstream side of the plurality of feed rollers in a medium conveying direction and also in a central part in a direction perpendicular to the medium conveying direction, to detect the medium, a second sensor and a third sensor located on both sides of the first sensor in the direction perpendicular to the medium conveying direction, to respectively detect the medium, and a processor to change the speed of one of the plurality of feed rollers at least until the first sensor detects the medium when any of the second sensor or the third sensor detects the medium and the first sensor does not detect the medium within a predetermined time.

A sheet conveying apparatus including: a locking member having an abutment surface abutting a sheet to correct skew feed of the sheet; a holding member configured to hold the locking member to rotate from a waiting position when the locking member is pushed by the sheet; a roller pair configured to nip the sheet abutting the abutment surface; a first urging portion configured to urge the holding member to the waiting position; a movable support portion configured to support the locking member in a manner that the locking member is located a retracted position where the locking member contacts a surface of the sheet and allows the sheet to pass; and a second urging portion configured to urge the locking member to a position where the abutment surface abuts a succeeding sheet.

An apparatus for aligning notes of value along a transport path has a note reader with a scanning line with areas detection areas there along. The scanning areas are arranged along a line orthogonally with respect to a central axis of the transport path. A first and at least one second transport elements serve to transport the note along the transport path in at least one transport direction. The transport elements each contact the note in a contact area. At least one aligning apparatus is used for aligning the note, which is arranged between the first and second transport elements and forms a section of the transport path. The note reader detects the trailing edge of the note in a first scanning area and in a second scanning area.
