PURPOSE:To obtain a register mark measuring apparatus which has a low cost, can automate a measuring operation and in which a measured result is corresponded to a sheet size. CONSTITUTION:A register mark measuring apparatus comprises mark detecting means 7 for photoelectrically detecting presence or absence of a register mark 2 printed on a sheet 1, moving means for moving the means 7 arbitrarily in an X direction/Y direction of a table surface 3 of an operation stand, position detecting means for detecting a moved amount of the means 7 by the moving means and detecting a position of the means 7, and calculating means for calculating a position of the mark 2 on the sheet based on positional information by the position detecting means. |
