Abstract
Apparatus for separating and removing a sheet from a stack of such sheets is provided with a reciprocating pushing member engaging the trailing edge of the lowermost sheet in the stack to push the same into contact with transport means capable of engaging the leading edge of the sheet for further transportation thereof. The pushing member has a pushing surface extending perpendicular to the surface supporting the stack and with a lower edge which, in the operative position of the pushing member, is substantially at the level of the stack supporting surface. The apparatus is particularly suitable for feeding film sheets from a cassette at a relatively high rate.
Claims1
An apparatus for separating and removing a sheet from a stack of sheets which comprises:
- support means for supporting said stack of sheets about longitudinal edges thereof;
- and
- pushing means for engaging the lowermost sheet in said stack reciprocating in a direction of transport between a point at which the lowermost sheet contacts a pushing surface of said pushing means at the rear of said stack for the transport of said lowermost sheet to a point of further transport of said sheet, said pushing means being comprised of a block-shaped member having an upper surface inclined downwardly to the direction of transport and having a groove formed in said upper surface transverse to said direction of transports, said groove having a difference in height between a front and rear edge thereof thereby forming said pushing surface, said pushing means being provided with at least one pin extending at right angles to said upper surface and disposed in a guide in a reciprocating drive member arranged for controlled reciprocating movement, said pin being spring-biased upwardly relative to said reciprocating drive member.
