Patent ID: 8375854

Claim:
A sheet process apparatus comprising: a first cylinder which receives a sheet from an upstream transport cylinder and holds the sheet; a second cylinder which is disposed to oppose said first cylinder and prints/coats the sheet held by said first cylinder; a third cylinder which is disposed to oppose said first cylinder and supplies ink/varnish to a circumferential surface of said first cylinder; first driving means for adjusting a gap amount between said first cylinder and said upstream transport cylinder, second driving means for adjusting a position of said second cylinder with respect to said first cylinder; third driving means for adjusting a position of said third cylinder with respect to said first cylinder; thickness input means for inputting a thickness of the sheet; and control means for controlling said first driving means, said second driving means, and said third driving means in accordance with the sheet thickness from said thickness input means, gap amount input means for inputting the gap amount between said first cylinder and said upstream transport cylinder, wherein said control means further controls said first driving means in accordance with the gap amount from said gap amount input means; wherein said control means controls said first driving means in accordance with the gap amount based on the sheet thickness from said sheet thickness input means, to set a position of said first cylinder at a reference position, and controls said first driving means in accordance with the gap amount adjusted by said gap amount input means, thereby finely adjusting the position of said first cylinder.
