Abstract

PURPOSE:To transfer sheets regularly constantly and prevent a diagonal transfer by performing sliding of a pair of guide members smoothly and secure positioning and fixing an interval corresponding to the size of the sheet material. CONSTITUTION:After a pair of guide members 6 are positioned, documents P are set on a slide regulation member 15 between the guide members 6. The documents P are transferred into a processing part 3 one by one and are discharged to a paper part 4 after a predetermined process is applied. Even if a side edge of the documents P rubs a side plate 8 while the paper P is discharged, or the documents P are vibrated or inclined for any reason, the slide regulation member 15 is assembled in a recess part 9, so that side plate 8 is engaged in a cut 16. This engagement prevents an interval L5 between the guide members 6 from being enlarged. The paper P is therefore transferred normally into the processing part 3 normally, thereby a diagonal transfer will not occur.

(Effects of the Invention) Since the present invention is configured as described above, it is possible to smoothly slide the pair of guide members before the slide regulating member is assembled. In addition, by meshing the holding means of the pair of guide members with the size reference means of the slide regulating member, the distance between the pair of guide members can be accurately positioned and fixed according to the size of the sheet material, so that the distance between the pair of guide members can be accurately positioned and fixed. Even if the side edge of the sheet material rubs against the guide member due to the conveying force, or if the sheet material vibrates or tilts for some reason, the distance between the pair of guide members will not change (increase). Therefore, the sheet material is always conveyed regularly and diagonal conveyance does not occur.
