Claim:
1. A sheet conveying apparatus comprising: a rotation axis rotatable in a predetermined rotating direction, and including a first portion to be engaged that is integrally rotated with the rotation axis, and a second portion to be engaged that is integrally rotated with the rotation axis; a first rotating member including a first sheet abutting portion that is configured to abut on a conveyed sheet and a first engaging portion that is engaged with the first portion to be engaged, and rotatably provided on the rotation axis, the rotation axis being rotated in the predetermined rotating direction in a state where the first engaging portion and the first portion to be engaged are engaged, by the first rotating member being rotated in the predetermined rotating direction, by the first sheet abutting portion being pressed by the conveyed sheet; a second rotating member including a second sheet abutting portion that is configured to abut on the conveyed sheet and a second engaging portion that is engaged with the second portion to be engaged, and rotatably provided on the rotation axis, the rotation axis being rotated in the predetermined rotating direction in a state where the second engaging portion and the second portion to be engaged are engaged, by the second rotating member being rotated in the predetermined rotating direction, by the second sheet abutting portion being pressed to the conveyed sheet; a detector that is configured to detect that the sheet has passed through a sheet conveying path, according to movement of the first rotating member or the second rotating member; a positioning unit that is configured to position the rotation axis to a stop position by rotating the rotation axis in the predetermined rotating direction; a first force applying member that is configured to apply a force to the first rotating member to cause the first rotating member to be rotated in the predetermined rotating direction; and a second force applying member that is configured to apply a force to the second rotating member to cause the second rotating member to be rotated in the predetermined rotating direction, wherein in a case that the second rotating member engages with the second portion, the second rotating member rotates together with the first rotating member, and in a case that the second rotating member contacts with the conveyed sheet in a status that the rotation axis and the first rotating member are stopped by the positioning unit, contact status of the second rotating member with the conveyed sheet is cancelled as the conveyed sheet passes the second rotating member and the second rotating member rotates independently from the first rotating member by the second force applying member.
