These are both sides of the roller sensor. Can someone confirm what kind is it? Is it ir diode and phototransistor? What would the diagram be for this circuit/switch?
thanks a lot!

The one labeled "PT" is likely the phototransistors, and the side labled "IR" is likely the infrared LEDs.

 

Also, this dude's project page has a picture of the schematic symbol.
