Abstract
An optical sensor for detecting the presence or absence of sheet products in a moveable device has a fixed light source, a fixed light detector spaced from the fixed light source, and a light transfer device fixedly connected to the moveable device for directing light from the fixed light source to the light detector as the moveable device passes by the fixed light source. Also disclosed is a device for transferring and moving sheet products and a method for detecting sheet products by an optical sensor having the steps of inserting a first sheet product into a first moveable device, aligning the first moveable device with a fixed light source and a fixed light detector, and transmitting light from the fixed light source across an opening of the first moveable device.
