５はピンチローラを示す。Embodiment An embodiment of the present invention will be described in detail with reference to the drawings shown in FIG. For example, the paper 2 that has been transported at a speed V O is fed by a transport roll 3 . The main body 1 consists of a plurality of conveyor belts, for example three conveyor belts 6, wound between a pair of rolls 4 and 5, and a positioning belt 7, for example two conveyor belts, provided between these conveyor belts 6. The belt 7 is wound between a drive roll 9 and a driven roll 10, which are rotated by a drive source 8 such as a stepping motor, and is rotated in the same direction as the conveyor belt 6 at a speed V G that is slower than the above-mentioned speed V O. It is becoming more and more like this. Further, on the upper surface of each positioning bolt 7, a gate 11 having a concave groove 11a into which the leading edge of the paper 2 enters is protruded from the paper introduction side, and a sliding plate is provided above each conveyor belt 6 in parallel with the gate 11. 12 are provided. The sliding plate 12 is curved upward in an arc shape at the end on the paper input side, so that the leading edge of the paper 2 can easily enter between each conveyor belt 6 and the sliding plate 12, and the upper surface of each sliding plate 12 A plurality of support rods 12a are protruded from the support rods 12a, and the upper ends of these support rods 12a are supported by a frame 13 on the copying machine side so as to be movable up and down.
In addition, each support rod 12a has a sliding plate 12 and a frame 1.
Compression springs 14 are provided between the conveyor belts 3 and 3, and these compression springs 14 lightly press each sliding plate 12 against the upper surface of the conveyor belt 6. Note that 1 in the figure
5 indicates a pinch roller.

る。Effects of the Invention As described in detail above, in this invention, since the sliding plate 12 is provided above the conveyor belt 6, even if the sheet 2 fed by the conveyor roll 3 is thin, the gate of the positioning belt 7 Since the sliding plate 12 prevents the sheet 2 from buckling by contacting the sheet 11, it is possible to prevent the sheet 2 from buckling and causing a paper jam. Further, since the conveying force of the conveying roll 3 can be increased, even thick sheets of paper 2 can be reliably fed until they contact the gate 11, so that thick sheets of paper 2 can be positioned with high precision.
