Morphology
The meaning 'a device that projects images from above' is directly derivable from combining 'overhead' (positioned above) with 'projector' (a device that projects visual content). This noun compound follows standard compositional patterns and would be understandable to a B1 learner who knows both constituent words.
Etymology
Overhead projector comes from a simple picture: the projector shines the picture of a clear sheet up and overhead the people in the room onto a screen. That's why the phrase means the device used in classrooms or meetings to show pages to a group.
