Sheet Conveyance Apparatus Ensuring Reduced Damage of Stopper

摘要

A sheet conveyance apparatus includes a sheet conveyance path, a sheet feeding member, a driving mechanism, a stopper, an interlocking portion, a cover member, and an evacuation mechanism. The stopper is configured to change a posture between a projection posture and an evacuation posture. The projection posture is configured to project into the sheet conveyance path so as to prevent the sheet to be loaded on a sheet loading portion from abutting on the sheet feeding member. The evacuation posture is configured to evacuate the stopper from the sheet conveyance path. The evacuation mechanism is configured to: change the stopper to have the evacuation posture, or to be in a posture changeable state where the stopper changes from the projection posture to the evacuation posture by application of external force, in conjunction with a change of the cover member from a closed state to the open state.

1. A sheet conveyance apparatus, comprising:
a housing; a sheet loading portion arranged at the housing, a sheet being to be loaded on the sheet loading portion; a sheet conveyance path that extends from the sheet loading portion in the housing, the sheet being to be conveyed in a predetermined conveyance direction through the sheet conveyance path; a sheet feeding member arranged at an inlet side of the sheet conveyance path, the sheet feeding member being configured to convey the sheet by being rotated; a driving mechanism configured to rotate the sheet feeding member; a stopper configured to change a posture between a projection posture and an evacuation posture at an upstream with respect to the sheet feeding member in the conveyance direction, the projection posture being configured to project into the sheet conveyance path so as to prevent the sheet to be loaded on the sheet loading portion from abutting on the sheet feeding member, the evacuation posture being configured to evacuate the stopper from the sheet conveyance path; an interlocking portion configured to fix the stopper to the projection posture or the evacuation posture in conjunction with the rotation of the sheet feeding member; a cover member that supports the sheet feeding member and the stopper, the cover member being openable/closable to the housing, the cover member in an open state opens the sheet conveyance path to an outside of the housing; and an evacuation mechanism configured to:
change the stopper to have the evacuation posture, orto be in a posture changeable state where the stopper changes from the projection posture to the evacuation posture by application of external force,in conjunction with a change of the cover member from a closed state to the open state.
