An automatic paper feed device is provided, including (1) a placement unit in which paper is placed, (2) a separation and transport mechanism that separates paper placed in the placement unit and transports paper placed in the placement unit in a transport direction, and (3) a cover member that has a paper insertion opening in a nearly rectangular shape, the paper insertion opening having a longitudinal direction perpendicular to both a transport direction of the paper and a thickness direction of the paper. The paper insertion opening includes a first end opening portion, a second end opening portion, and a center opening portion. The center opening portion is located in a position corresponding to the separation and transport mechanism. The first end opening portion is disposed on one side of the center opening portion in the longitudinal direction of the paper insertion opening, and the second end opening portion is disposed on the other side of the center opening portion in the longitudinal direction of the paper insertion opening. The cover member covers the separation and transport mechanism. The paper insertion opening connects the placement unit with the separation and transport mechanism. The separation and transport mechanism is provided in a position corresponding to a nearly central location of the longitudinal direction of the paper insertion opening from the perspective of a head on view of the paper insertion opening. The first and second end opening portions are each larger in size than the central opening portion.
