When attaching to the main body of the copying machine, as shown in Fig. 4, adjust the height of the hinge 23 that pivots on the rear side up and down with a spacer, and also adjust the position of the magnet catch 24 on the front side up and down. It was necessary to adjust the distance between the conveying section 31 and the contact glass 22 so that the stoppers 39 provided on the upper side of the conveying section 31 in the front, rear, left, and right directions evenly contacted the upper surface of the contact glass 22. This adjustment needs to be done for each machine and is tedious, and if the adjustment is insufficient, the endless belt 34 may hit unevenly and the document may be fed diagonally onto the contact glass, or the document may not be fed enough. This causes the inconvenience of jamming.

トッパ１０が設けられている。To explain in more detail, in the conveyance section, one endless wide belt l is stretched around rollers 2.3 that are pivotally supported by the front side plate 11 and the rear side plate 12 of the conveyance section, and the lower running part is
It is pressed downward by a plurality of pressure rollers 4 supported by bearings provided on a pressure plate 6 extended between J and the rear side plate 12. A compression spring 7 is interposed between the pressure plate 6 and the arm 8, and the pressure plate 6 is biased downward with respect to the arm 8. Inside the compression spring 7 is provided a stud 13 whose upper end is fixed to the arm 8 and whose lower end passes through a loose hole drilled in the pressure plate 6 and has an enlarged head at its lower end, so that the pressure plate 6 and The conveyance unit, which consists of front and rear side plates 11 and 12 fixed to this, rollers 2 and 3 that are pivotally supported on this, endless wide belt 1 that is wound around this, and pressure roller 4, is attached to the ADF main body only in the vertical direction. The enlarged head of the stud 13 prevents the transport section from moving out of the arm 8. Stoppers 10 projecting downward from the pressure plate are provided at a total of four locations on the left and right sides of the front and rear of the pressure plate 6, respectively.

安定した原稿搬送性を得ることができる。Therefore, if the amount of protrusion of the stopper IO is set in advance to a length that provides a predetermined distance between the transport section and the contact glass, even if the copying machine and the ADF are replaced, there is no need to make adjustments and the transport section will always be maintained. A predetermined value is obtained for the distance between the contact glass and the contact glass, and a constant pressure is applied by the pressure roller 4.
Stable document conveyance can be obtained.
