Title:
REGULATOR FOR POSITION OF PRE-REGISTER OF SHEET PRINTER
Document Type and Number:
Japanese Patent JPS6447543
Kind Code:
A
Abstract:

PURPOSE: To obtain movement at the desired positions of register marks accurately and quickly by inputting a pitch between the register marks on the operation side and reverse-operation side of a printing paper and movement to an input section.

CONSTITUTION: A setting means 6 for an input section 1 displays a pitch lbetween a register mark 4 on the operation side 3 of printing paper 2 and a register mark 5 on the anti-operation side 3', a setting means 7 indicates the movement (m) of the register mark 4 on the operation side 3, and a setting means 8 designates the movement (n) of the register mark 5 on the reverse- operation side 3'. Ink 9 inputs these numeric values to a central processing unit 10. A movement amount calculating arithmetic sections 10C at both ends of a pre-register shaft for the device 10 compute movement X, Y at both ends of the pre-register shaft 11 by the pitch l between both register marks 4, 5, the movement (m) of the register mark 4 and the movement (n) of the register mark 5 and the length L of the pre-register shaft 11. A working-quantity arithmetic section 10d respectively turns motors 12a, 13a for drivers 12, 13 on the basis of the movements X, Y being computed.
