1st folding control

A. Conveyance/folding switching control
The switching between conveyance and folding is made by moving the 1st folding roller /1. This switching is
made when the eccentric cam is driven by the 1st folding release motor (M14).
After the 1st folding conveyance sensor (PS51) turns ON, the paper is conveyed by a specified number of steps.
While the paper is being conveyed, the 1st 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, M14 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 1st
folding roller gears /1 [1] and /2 [4]. At the same time, when M14 starts up, the cam provided on the inside of the
1st roller gear /2 [4] rotates to allow the 1st roller /1 and 1st roller /2 to contact each other closely to rotate 1st
roller /1. get the gears engaged.
The phases of the 1st folding roller gears /1 [1] and the 1st 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.
