Title: Apparatus for tracing sheet of paper or the like
Inventor: NAKANO KAZUMI
IPC: B65H7/02
Filed: 1981-07-29
Abstract: PURPOSE:To enable sheets of paper to be traced even in the occurrence of abnormalities during conveyance by comparing conveying spacings at an inlet with that in an outlet to generate conveying number output corresponding to the result of the comparison. CONSTITUTION:Signals from sensors PS101, PS102 provided respectively at an inlet and outlet of a conveyer path with a predetermined length enter measuring circuits 22, 24 after they are shaped by amplifiers AMP101, AMP102. The measuring circuits 22, 24 comprise respectively a counter for generating conveying sequence cords indicating the conveying sequence every time said circuits detect sheets of paper, a counter for measuring on-time corresponding to the length of the sheet and a counter for measuring off-time corresponding to the conveying spacing of the sheets.

Title: Method and device for controlling printing register
Inventor: NOCHIDA HIROYUKI
IPC: B41F33/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To perform the setting of a timing and the revolution speed changing of a plate cylinder in a manner to keep a tension variation to the minimum to a slip amount by correcting a printing register slip to a printing unit on the upstream side in a specified range of the plate cylinder phase angle and/or a specified value of the plate cylinder revolution speed in a printing unit on the downstream side. SOLUTION: When a register regulator 21 receives a register mark detecting signal from a register mark detector 20, and an angle for a plate cylinder correction and an operation amount of the speed are output to a motion controller 27. A plate cylinder correction angle inputting device 24 sets a set value for the correction angle, and a plate cylinder correction speed inputting device 25 sets a set value for the correction speed, respectively for the register regulator 21. The regulator 21 corrects a printing register slip for a printing unit on the upstream side in a specified range for the plate cylinder phase angle, and at a specified value for the plate cylinder revolution speed, and sets a revolution speed variation of the plate cylinder to the printing register slip amount at a proper amount, and reduces a tension variation by the correction.  By this constitution, the correction can be performed by the optimum phase angle and revolution speed wherein the tension variation is taken under consideration.

When the scanning is executed by setting up the point 6 as the current point, the scanning arrives at a point 8 of which X and Y axes are changed and DELTAX=3 and #Y=1 are recorded by using the point 8 as the changing point. When the succeeding scanning is executed by using the point 8 as the current point, the scanning arrives at a point 9 of which X and Y axes are changed and DELTAX=-1 and DELTAY=2 are recorded by using the point 9 as the changing point. Points 10, 11 are adopted as the succeeding changing points, and finally the scanning arrives at the end point 5.
