A transport apparatus comprising: an apparatus body; an opening and closing unit attached to the apparatus body so as to be openable and closable between a closed position where an upper surface of the apparatus body is covered and an open position where the upper surface of the apparatus body is exposed, the opening and closing unit including, inside the opening and closing unit, a transport path along which a target material is transported; a transport path member that has a transport path surface constituting a part of the transport path, is rotatably supported by the opening and closing unit at one end portion side of the transport path member, and is configured such that the transport path is opened when the other end portion side of the transport path member moves downward from the opening and closing unit, wherein the one end portion side of the transport path member is on a downstream side of the other end portion side of the transport path member relative to a transport direction in which the target material is transported; and a hook portion that is rotatably attached to the other end portion side of the transport path member, wherein the hook portion is formed in a hook shape having a tip portion protruding toward the downstream side, wherein in a hooked state in which the tip portion of the hook portion is hooked on a hooked portion of the opening and closing unit, the hook portion is configured to hold the transport path member in a closed state of the transport path based on a force applied toward a first rotation direction along which the hook portion is hooked to the hooked portion, and characterized in that when the opening and closing unit is moved from the open position to the closed position in a non-hooked state in which the hook portion is not hooked on the hooked portion, the tip portion comes into contact with the hooked portion while the transport path member is pushed upward by the upper surface of the apparatus body, thereby rotating the hook portion in a second rotation direction opposite to the first rotation direction. an apparatus body; an opening and closing unit attached to the apparatus body so as to be openable and closable between a closed position where an upper surface of the apparatus body is covered and an open position where the upper surface of the apparatus body is exposed, the opening and closing unit including, inside the opening and closing unit, a transport path along which a target material is transported; a transport path member that has a transport path surface constituting a part of the transport path, is rotatably supported by the opening and closing unit at one end portion side of the transport path member, and is configured such that the transport path is opened when the other end portion side of the transport path member moves downward from the opening and closing unit, wherein the one end portion side of the transport path member is on a downstream side of the other end portion side of the transport path member relative to a transport direction in which the target material is transported; and a hook portion that is rotatably attached to the other end portion side of the transport path member, wherein the hook portion is formed in a hook shape having a tip portion protruding toward the downstream side, wherein in a hooked state in which the tip portion of the hook portion is hooked on a hooked portion of the opening and closing unit, the hook portion is configured to hold the transport path member in a closed state of the transport path based on a force applied toward a first rotation direction along which the hook portion is hooked to the hooked portion, and characterized in that when the opening and closing unit is moved from the open position to the closed position in a non-hooked state in which the hook portion is not hooked on the hooked portion, the tip portion comes into contact with the hooked portion while the transport path member is pushed upward by the upper surface of the apparatus body, thereby rotating the hook portion in a second rotation direction opposite to the first rotation direction.
