Patent ID: 7988144

Claim:
A mailpiece selector device for separating mailpieces one-by-one from a stack of mailpieces and for transporting them downstream, wherein said mailpiece selector device comprises: a first guide followed by a second guide, the first guide having a downstream end; and a plurality of opposite selector rollers cooperating with said first and second guides to select said mailpieces one-by-one and to transport them downstream, said first guide being adapted to pivot about a first pivot axis in opposition to first resilient return means, said second guide being adapted to pivot about a second pivot axis in opposition to second resilient return means, and said second pivot axis being offset upstream relative to said first pivot axis, and said first and second guides having drive means adapted to automatically pivot said second guide with said first guide when said downstream end of said first guide pivots a distance above a predetermined mailpiece thickness range, wherein said drive means comprise at least one bearing surface secured to or integral with said first guide and facing at a predetermined distance at least one abutment on said second guide, so that, as a mailpiece having a thickness in said predetermined mailpiece thickness range passes through, said first guide pivoting causes said second guide to pivot.
