An image-forming apparatus 1 has a paper cassette 3b therein. The paper cassette is installed into the apparatus along a guide channel 46 attached to a housing frame 45 of the apparatus. A housing 44 of the apparatus has a left side surface forming front and rear opening structures 9 at a lower portion. A hold 48 is provided on an inner-upper portion of the opening structure. The paper cassette has a left-side exterior portion 50 forming a recess 51 at a position facing the opening structure. A space 52 is prepared next to the recess without impairing the original function of the paper cassette. When moving the apparatus, a worker inserts his hand into the opening structures, touching the holds with his palms and flexes his fingers in the spaces, thereby firmly gripping the holds with his hand and lifting the printing apparatus in his arms.
