2nd folding control

A. Conveyance/folding switching control
The switching between conveyance and folding is made by moving the 2nd folding roller /1. This switching is
made when the eccentric cam is driven by the 2nd folding release motor (M15).
After the 2nd folding conveyance sensor (PS53) turns ON, the paper is conveyed by a specified number of
steps. While the paper is being conveyed, the 2nd folding roller gears /1 [1] and /2 [4] rotate in the same direc-
tion since these 2 gears are interlocked each other through the idle gear [2].
After conveying the paper by the prescribed number of steps, M15 rotates until it gets to a specified number of
steps. This rotates the eccentric cam [5] to allow the idle gear arm [3] to separate the idle gear [2] from the 2nd
folding roller gears /1 [1] and /2 [4]. At the same time, when M14 starts up, the cam provided on the inside of the
2nd roller gear /2 [4] rotates to allow the 2nd roller /1 [1] and 2nd roller /2 to contact each other closely to rotate
the 2nd roller /1.
The phases of the 2nd folding roller gears /1 [1] and the 2nd folding roller gears /2 [3] are not aligned in the
depth direction. Therefore, they do not engage with each other after the idle gear [2] has been separated.
