CHAPTER 3 EXPOSURE SYSTEM c. Moving the Copyboard Forward When the copyboard has moved in reverse and is positioned as shown in Figure 3- 105B, the start position cam pushes down the copyboard position sensor lever. When SL2 goes ON in this position, the forward/reverse switching mechanism moves to the position shown in the figure, causing the forward/reverse switching mechanism to engage with the forward gear; as a result, the forward gear rotates in the direction of the arrow, moving the copyboard forward.
