Automatic aligning device for recording sheets

Abstract

Abstract PURPOSE:To accomplish alignment of recording sheets with simple configuration by contacting and separating intermittently a follower roller with/from the drive roller to transport the sheets, and thereby allowing the sheets to receive a combination force oriented in the direction of alignment. CONSTITUTION:If a recording sheet 8 skews, a force of the A direction is generated along one of the diagonals of the sheet. On the other hand, the driving means including a follower roller 6 generates a force of B direction and applies it to the recording sheet 8. The force C as combination of these two is applied to the sheet 8 so as to drive it into alignment. Thus at the time of alignment of sheets 8 a drive roller 5 is rotated in a certain direction at a specific speed, and a cam 15 is rotated by motor 16. The cam 15 swings the above-mentioned follower roller 6 oscillatively through a working shaft 14 and follower roller shaft 13 and thereby contacts and separates the follower roller 6 intermittently with/from the drive roller 5. Thus the recording sheets 8 are driven intermittently, and the above-mentioned combination force C is applied to put the sheets 8 into alignment in the standard position.
