Title: Sheet conveying device and image forming device
Inventor: KOMINATO TAKANARI
IPC: B65H5/22
Filed: 1993-08-19
Abstract: PURPOSE:To absorb a shock when a sheet enters a nip on the lower course of a sheet conveyer, without using plural sheet conveying devices, by bending the sheet conveying surface in the direction the sheet is attracted. CONSTITUTION:A sheet 3 an image on a sensitive drum 1 is copied in a copy printer (a) is delivered to the left side following the rotation of the sensitive drum 1. The sheet is attracted to a sheet belt 8 rotating by the operation of a fan 9, conveyed downward along a sheet guide 18 being made in a projecting form, and then, the front edge of the sheet 3 enters the nip (b) of the fixing devices 10 and 11, and the sheet 3 is conveyed by the rotations of the fixing roller 10 and the pressure roller 11. As a result, even though there are a shock when the sheet enters the fixing part, a difference in speed between the transfer part and the fixing part, and a difference in generating line direction between the transfer part and the fixing part, when the rear end of the sheet 3 is still being transferred in the transfer part (a), a loop in a projecting form generated at the lower side of the sheet 3 absorbs those influences, and an adverse effect on the transfer image can be avoided.

Filed: 1988-09-12
Abstract: PURPOSE: To produce signatures forming no crease after folded along an intended fold line by providing many U-shaped perforations where the signatures are alternately placed the other way along or near the fold line. CONSTITUTION: A perforating tool 6 conducts perforation on multilayered signatures 9 so that the signature 9 has many U-shaped perforations 35, 40 and 41 alternately placed the other way along or near the fold line 36. However, because a web 39 does not exist between the bottom cuts 35.1 and 35.2 widely perforated by perforating teeth 24.1 and 26.1, the fold line 36 has a slit-shaped perforation with double length there. Therefore, almost no crease is formed when signature perforated with the perforating tool is folded along the fold line.
