PROBLEM TO BE SOLVED: To easily grasp whether a support member for fall prevention is attached without turning on power when a center of gravity of an entire device is higher than a predetermined level due to mounting of a recording medium supply unit on an image recording part body.SOLUTION: An extension paper feed unit 80 has a movement member 94 movable in a vertical direction. When a plurality of paper feed units 80 are layered on a device body 101, a lower end part 94b of the movement member 94 of the lowest extension paper feed unit 80 is housed in a second recessed part 92 of a stabilizer 190 to be normally mounted only when the stabilizer 190 is mounted on the lowest extension paper feed unit 80. When another extension paper feed unit 80 is layered on the device body 101, the extension paper feed unit 80 is normally mounted because an upper end part 94a of the movement member 94 is housed in a first recessed part 91 of the device body 101 even though the stabilizer 190 is not mounted on the extension paper feed unit 80. |
