Abstract:
1. An image reading device comprising: a main unit; a scanning unit located above the main unit and configured to move relative to the main unit between a first base position and a first moved position, and scan an original sheet; a conveyance unit located above the scanning unit and comprising a tray and a cover member, and being formed with a first opening and a second opening, the conveyance unit configured to convey the original sheet along one of a first conveying path and a second conveying path, the first conveying path extending from the tray to the first opening, and the second conveying path extending from the tray to the second opening, the conveyance unit configured to move relative to the scanning unit between a second base position and a second moved position, the cover member configured to move between a third base position at which the cover member covers the second opening and a third moved position at which the cover member does not cover the second opening; a first detector configured to detect a first state and a second state, the first state including one of a case (a) where the scanning unit is at the first base position, the conveyance unit is at the second base position, and the cover member is at the third base position, and a case (b) where the scanning unit is at the first base position and the conveyance unit is at the second moved position, and the second state including one of a case (c) where the scanning unit is at the first base position, the conveyance unit is at the second base position, and the cover member is at the third moved position, and a case (d) where the scanning unit is at the first moved position; and a second detector configured to detect a third state in which the scanning unit is at the first base position, and the conveyance unit is at the second base position, and a fourth state including one of a case (e) where the scanning unit is at the first moved position, and a case (f) where the conveyance unit is at the second moved position, wherein the conveyance unit is configured to convey the original sheet along the first conveying path when the first detector detects the first state and the second detector detects the third state, and to convey the original sheet along the second conveying path when the first detector detects the second state and the second detector detects the third state.
