Abstract

Improved apparatus for viewing of slides, provided with a device for advancing and centering films slides and especially for a film including pairs of stereoscopic frames, characterized in that it includes a tooth (18) for the film intended to engage by elastic stress a centering hole of a row of holes (16) formed in the film for centering; curved means (70-72) including a ramp profile (106) and an elastically susceptible portion (102) which is manually controlled to drive an active stroke against the reaction of an opposing spring, during which active stroke the tooth is raised first of the ramp and then a film feed transmission is actuated until the tooth which in the meantime slips from the ramp a subsequent hole (16) of the film; said transmission including a unidirectional coupling, that is, a free wheel, and allowing said portion to yield, with the return, returning the cursors the state of providing an additional active stroke.
