Abstract
An upper case 5 is pivotable with respect to a case 2 by attachment with two frames 37. A sheet-supply tray 6 is pivotably mounted on the upper case 5. The sheet-supply tray 6 has a pair of left and right guides 35, 35 at a position near a sheet-supply port 13. The guides 35, 35 have a pair of separation ribs 42, 42 that define therebelow a sheet-supply pathway and thereabove a sheet discharge pathway. A synthetic resin hollow frame 40 with an integral slide rib 41 is fixed to the case 2. The slide rib 41 is formed with an outwardly curving surface 41a that is eccentric with an imaginary circle around a pivot shaft 38 of the upper case 5, wherein the free end of the slide rib 41 is farther from the shaft 38 than the fixed end. A horizontally protruding pin is fixed on one of the frames 37, and so pivots following the imaginary circle around the shaft 38. When the upper case 5 is pivoted wide open, the pin 39 pressingly slides against the outwardly curving surface 41a of the slide rib 41, until the pin 39 reaches near the free end of the outwardly curving surface 41a, where the pin 39 is held in a desired opened position.
