Slide projector for ring-shaped magazines - has section with a slotted cylindrical wall and transparency insertion device

摘要

The slide projector is one wherein the housing defines an annular chamber surrounding a hollow inverted cup-shaped housing section and serving to receive a ring-shaped magazine which is centered by the cup-shaped section. The cylindrical wall of the section has a vertical slot and the section shields and normally receives one arm of a slide changing mechanism which can be moved radially of a properly inserted magazine along a horizontal path to pass through the slot and expel a photographic transparency from that compartment of the magazine which registers with the slot. This enters a slide gate which is located between the projector lens and the projection lamp.
