<p><P>PROBLEM TO BE SOLVED: To provide a form paper conveyance device having a plurality of form paper conveyance means for conveying form paper and using a stepping motor to drive the form paper conveyance means at a downstream side which is capable of preventing the desynchronization of the stepping motor, and preventing paper jam. <P>SOLUTION: The paper conveyance device is provided with a first form paper conveyance means (a first conveyance means), a second form paper conveyance means (a second conveyance means) C2<SB>1</SB>, provided at the downstream side of the conveyance direction for the first form paper conveyance means, a first driving means for driving the first conveyance means, a second driving means M2 for driving the second conveyance means C2<SB>1</SB>and an acceleration sensor S3 as a vibration detection means for detecting vibration generated at the second driving means M2. When the fist conveyance means and the second conveyance means C2<SB>1</SB>convey the same form paper at the same time, a driving speed of the first driving means is controlled based on the information of vibration detected by the acceleration sensor S3 when the rear end of the form paper to be conveyed passes through the first conveyance means. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
