For this reason, when an impact is applied to the sheet conveying device due to dropping of the sheet conveying device or the like when a product including the sheet conveying device is transported, the tray unit or the cover unit may be detached from the casing.

  An object of the present invention is to provide a sheet conveying apparatus that can prevent the opening / closing member from being detached from the casing during transportation or the like.

  In order to achieve the above object, a sheet conveying apparatus according to one aspect of the present invention includes a housing and a rotating edge extending in a predetermined direction, and is parallel to the rotating edge with respect to the housing. An opening / closing member provided so as to be openable and closable around a rotation axis, configured to place a sheet in an opened state, and configured to cover a part of the housing in a closed state. ing. And the said housing | casing is provided so that it can contact | abut to the said rotation edge, and is provided with the control part which controls the movement of the said opening / closing member of the closed state in the said predetermined direction.

  According to this configuration, the opening / closing member includes the rotating end edge extending in the predetermined direction. The opening / closing member is provided so as to be openable and closable around a rotation axis parallel to the rotation edge with respect to the housing. The sheet can be placed on the opening / closing member in a state where the opening / closing member is opened. In addition, a part of the housing is covered by the opening / closing member in a state where the opening / closing member is closed.

  The housing is provided with a restricting portion. The restriction portion restricts movement of the closed opening / closing member in a predetermined direction.

  For this reason, even when an impact is applied to the sheet conveying apparatus in a state where the opening / closing member is closed, the movement of the opening / closing member in a predetermined direction is restricted, so that the opening / closing member can be prevented from being detached from the casing.

  The restricting portion may be formed in a plate shape extending from the housing in a direction orthogonal to the rotation axis. The opening / closing member has a first facing portion that faces the restriction portion from one side in a predetermined direction when the opening / closing member is closed, and a predetermined direction with respect to the restriction portion when the opening / closing member is closed. And a second facing portion facing from the other side opposite to the other side.

  The movement of the opening / closing member to one side in the predetermined direction is restricted by the second facing portion coming into contact with the restriction portion. Further, the movement of the opening / closing member to the other side in the predetermined direction is restricted by the first facing portion coming into contact with the restriction portion. As a result, the movement of the opening / closing member to one side and the other side in the predetermined direction is restricted.

The opening / closing member has a notch. The notch has a concave shape that opens to the protruding portion side when the opening / closing member is closed.

  Then, in a state where the opening / closing member is closed, the protruding portion enters the cutout portion. As a result, both side surfaces of the notch in the predetermined direction face the protrusion from the predetermined direction, and movement of the opening / closing member in the predetermined direction is restricted.

  For this reason, even when an impact is applied to the sheet conveying apparatus in a state where the opening / closing member is closed, the movement of the opening / closing member in a predetermined direction is restricted, so that the opening / closing member can be prevented from being detached from the casing.

  The sheet conveying device preferably includes a pair of side covers facing the opening / closing member from both sides in a predetermined direction.

  The pair of side covers can also restrict movement of the opening / closing member in a predetermined direction. As a result, it is possible to further prevent the opening / closing member from being detached from the housing.
