Abstract: A sheet pressing apparatus includes a cam, lever, sheet press member, and first and second compression coil springs. The cam has a cam surface and is supported rotatably. The lever supports a cam follower that abuts against the cam surface and is pivoted by rotation of the cam. The sheet press member is movably supported by the lever and moves between a sheet press position to press a stacked sheet and a retreat position retreated from the sheet press position in accordance with swing motion of the lever. The first and second compression coil springs are arranged between the lever and a support, and bias the lever to bring the cam follower into tight contact with the cam surface. The second compression coil spring has a biasing force larger than that of the first compression coil spring. When the sheet press member is located at the sheet press position, only the first compression coil spring biases the cam follower with respect to the cam surface.
