<p>PROBLEM TO BE SOLVED: To supply and feed sheet stably by supporting a sheet loading means in a horizontal condition in such a manner that it can be inclined freely, regulating the direction of width of sheet, and raising sheet up to a position where sheet can be supplied and fed by an energizing means to regulate a rise amount of the sheet loading means. SOLUTION: An intermediate plate 312 as an envelope loading plate which becomes a sheet loading means is supported by a spring 311 which becomes an energizing means fixed on a bottom plate 306 in a spring receive part 312a in such a manner that the intermediate plate 312 and the spring 311 move vertically and integrally and is energized upward at all times. A guide groove 310 is provided in a side regulation plate 309, and a recessed part 314 provided in the intermediate plate 312 is engaged with the guide groove 310 so that the intermediate plate 312 can travel in the vertical direction for the side regulation plate 309 in order to constitute an oscillation support means which supports the intermediate plate 312 which is the sheet loading means in a horizontal condition in such a manner that it can be inclined freely. A claw 315 which becomes a rise regulation means on more downstream side in the direction of sheet supply and feed than the spring 311 is provided in an upper end part of the side regulation plate 309.</p> |
