Title: Thin sheet ejector
Inventor: IWATA KOUTEI
IPC: B65H3/56
Filed: 1980-03-12
Abstract: PURPOSE: To make it possible to reliably draw out one or a given number of thin sheets at a time even if said sheets contain water by a method wherein the thin sheets piled up in a containing box are ejected on at a time and transferred onto a bed plate automatically.  
     CONSTITUTION: When an ejecting plate 15 moves forward, a shutter 18 opens and a thin sheet 11a at the bottom contacts with a jaw 15c of a step 15a. Accordingly, as the ejecting plates 15 moves forwards, the thin sheet 11a is ejected from the ejecting-side opening in the containing box 12. At this time, a subsequent thin sheet 11b also tries to move with the thin sheet 11a, owing to the contact frictional force. However, because the ejecting-side opening has an aperture smaller than the thickness of the two sheets, the thin sheet 11b is blocked. When the thin sheet 11a has been completely ejected from the containig box 12, the shutter 18 rotates counterclockwise with its own weight to return to the initial position, so that the ejecting- side opening is closed.
