<p>PROBLEM TO BE SOLVED: To obtain an image forming device capable of double-sided printing to which a paper supply cassette is detachably attached and where a paper supply unit is increased without increasing ground area from an initial state at all by providing the paper supply unit increased in a state where a basic image forming device is laminated and mounted thereon. SOLUTION: A printer main body 21 is provided with a face-down stacker 30 on its upper surface and a housing space part 31 on its lower surface side. The space part 31 is formed between leg parts 32 and 33 projected downward from the right and left sides of the main body 21, and ordinarily the paper supply cassette 22 is inserted from a front aperture 35 and attached in the space part 31 so that it can be drawn out. A paper carrying unit 23 is provided with a paper carrying roller for carrying paper to the inside for the purpose of the printing of a back surface, and has the same outside shape as the cassette 22. By pulling out the cassette 22 and attaching the paper carrying unit 23 instead of the cassette 22, double-sided printing can be performed in addition to single-sided printing.</p> |
