Theory of Operation Ver2.0 Sep.2006
B. Tri-folding control
(1) Operation
After the initial operation, the 1st folding blade [8] is at the standby position /1 [5]. In the actuator [7], the 1st fold-
ing blade home sensor /2 (PS21) [3] turns ON and the 1st folding blade home sensor /1 (PS20) [6] turns OFF.
When the paper [9] is conveyed to the folding section and the 1st folding blade motor (M18) is rotated [2], the
crank [4] rotates 90° to project the 1st folding blade to the paper and push the paper [12] between the folding
roller /1 [10] and /2 [11] with its edge. At the time, the actuator also rotates 90° so that PS21 [3] and PS20 [6]
turns OFF and ON respectively.
M18 keeps rotating in the same direction [13], and then the crank [4] stops when it reaches at the standby posi-
tion /2 [1] (PS20 turns OFF) where is 180° opposite from the standby position /1. In the 1st folding operation for
the subsequent set, M18 rotates in the reverse direction [14] and the crank [4] also rotates 180° in the reverse
direction to conduct the 1st folding operation.
The 2nd folding operation is operated as in the 1st folding operation.
