How do the so-called non-flicker editors work? Do they have a different film head design than Sansei Koki seems to have supplied for most ordinary viewers?

They use prism mechanism.

So every frame will overlap with the next frame resulting non flicker picture.

But beware, as far as I am concerned all GOKO non flicker editors, due to this prism, do not have strong light on screen. Picture also not as sharp as the ordinary editors.

Let me see if I understand this, then: using a rotating prism that can "see" more than one frame at a time, light from at least one frame always fills the screen, right? Depending on how many sides the prism has, it would show bits of a frame or two on either side of the frame centred on the gate.

I suppose this would imply that the both condenser lens and gate are larger than for a four-sided rotary prism viewer, too, since adjacent frames need to be illuminated at the same time. Is the gate also curved? Or would that be only for high-end projectors?

I think your understanding is quite right.

In short, the changing pictures between frames is done by (sort of) fade-in/fade-out process instead of one in/one out that most projector/editor does (which resulting flickers, hence we call them flickers picture [Wink] ). Only if you go further to more technical things, I could not explain as I am a very layman.
