Abstract
1379280 Slide projectors EASTMAN KODAK CO 28 Sept 1972 [30 Sept 1971] 44831/72 Heading G2A After projection at a gate 2, slides 30 are fed into a chamber 4 to form a stack 32 which builds up obliquely to the direction of the path along which the slides enter the chamber, the slides joining the top of the stack until it reaches a certain size whereupon the next slide to enter the chamber is deflected to pass alongside the stack 32 to an extension 8. As shown, a flange 15 is pivoted into the slide path in synchronism with slide changing. If the stack is not full slides fall on to the top of the stack before flange 15 is pivoted. If the stack is full the next slide rests vertically thereon and then is deflected by flange 15 into the extension 8. In Figs. 5, 6 (not shown) a lever (24) is also pivoted in synchronism with slide changing in order to eject slides from the extension 8.
