Abstract
An apparatus for conveying sheet-like recording carriers, such as paper, cards or envelopes without adjusting for their relative thicknesses is disclosed. In the conveying path of a sheet from a supply stack to a driven platen, a baffle plate and a deflecting surface are disposed as a separating device. The deflecting surface causes a pressure on the edge of the baffle plate to be exerted against the conveyed sheet due to the deflection by the deflecting surface. As a result, a sheet moving along beneath the conveyed sheet will abut with its forward edge against the surface of the baffle plate and is detained until the previously conveyed sheet vacates the baffle plate.
Claims9
An apparatus having means for successively removing sheet-like recording carriers from a supply stack and for conveying the carriers into a predetermined path, means for biasing the stack so that the carrier at one end of the stack is urged into engagement with the removing and conveying means and stop means engageable with the forward edge of the supply stack relative to the path, the combination of means for assuring successive conveyance of the carriers one-by-one in the predetermined path, comprising:
- a first element disposed along the path beyond the stop means on the opposite side of the path from the removing and conveying means, said element having an edge engageable and transversable by a carrier traveling along the path and having a surface facing the stack and extending from said element edge away from the path at an inclination toward the stack;
- and
- a second element disposed along the path and on the same side thereof as the removing and conveying means, said second element having a surface disposed along the path beyond said first element, said surface being engageable by a carrier and inclined in the direction of movement thereof to deflect the carrier and hold it against said edge of said first element;
- whereby if two carriers are removed at once from the stack and traverse the stop means, the forward edge of the second carrier will abut said surface of said first element and be prevented from passing over said edge thereof by the first carrier until the latter becomes free from engagement with the removing and conveying means.
