3rd folding control

A. Conveyance/folding switching control
The switching between conveyance and folding is made by moving the 3rd folding roller /1. This switching is
made when the eccentric cam is driven by the 3rd folding release motor (M16).
After the 3rd folding conveyance sensor (PS54) turns ON, the paper is conveyed by a specified number of steps.
While the paper is being conveyed, the 3rd folding roller gears /1 [1] and /2 [4] rotate in the same direction since
these 2 gears are interlocked each other through the idle gear [2].
After conveying the paper by the prescribed number of steps, M16 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 3rd
folding roller gears /1 [1] and /2 [4]. At the same time, when M16 starts up, the cam provided on the inside of the
3rd roller gear /2 [4] rotates to allow the 3rd roller /1 [1] and 3rd roller /2 to contact each other closely to
rotate the 3rd roller /1. The plases of the 3rd folding roller gears /1 [1] and the 3rd folding roller gears /2 [3] are
not aligned in the depth direction. Therefore, they do not engage with each other the idle gear [2] has been sep-
arated.
