This sheet feeding device (1) is provided with a cassette (10), a size detection unit (60), and a mounting detection unit (30). The size detection unit (60) detects the size of a sheet loaded on the cassette (10). The size detection unit includes an interlocking member (61) and a switch unit (81). The interlocking member (61) includes a plurality of members for size detection (64) and moves in response to the sliding of a restricting member (11). The switch unit (81) detects the position of the restricting member (11) on the basis of the state of a switch (82) that detects the members for size detection (64). The mounting detection unit (30) includes a member for mounting detection (31) and a mounting detecting member (41). The mounting detecting member (41) detects the member for mounting detection (31) in response to the mounting of the cassette (10). In response to detection of the mounting of the cassette (10) by the mounting detection unit (30), a control unit (70) detects the size of the sheet on the basis of the state of the switch unit (81). |
