A roller is rotatably provided in an arm that is swingable relative to a main body of an apparatus, and is connected to a tension spring using a wire of a roller shaft. A roller guide portion that guides the roller is provided in a sheet feeding cassette. The roller is guided along a guiding member of the roller guide portion in accordance with insertion of the sheet feeding cassette into the main body of the apparatus. When the roller is guided along the guiding member, an elastic force of the tension spring is accumulated. The sheet feeding cassette is pulled to a mounting position when the roller is guided along the guiding member. The sheet feeding cassette is pushed out also when the roller is guided along the guiding member.
