To provide a means for preventing deformation of a roller by conveying a tray.

A composite machine 10 includes: a conveyance path 65 by which recording paper is conveyed; a media tray 71 of flat plate shape, on which the conveyance path 65 can pass; a discharge roller 62 and a spur 63; rollers 66 and 67 for tray with diameter smaller than the discharge roller 62, prepared in the same rotary shaft 61 with the discharge roller 62; and a recording part 24. The media tray 71 is protrusions 78 and 79 projecting from a lower surface 77 only for dimension D1 which is larger than the difference between radius R1 of a discharge roller 62 and radius R2 of rollers 66 and 67 for trays, and extended along the longitudinal direction 106 at positions corresponding to the rollers 66 and 67 for trays in the lower surface 77.
