Abstract
A sheet feeding mechanism is described in which the sheets in a batch of sheets are sorted into different output stackers. The sheet feeding mechanism includes a buffer store for receiving and temporarily holding a batch of sheets while a predetermined batch value is verified, and a batch verifier responsive to the passage of each sheet along a given path for comparing a measured batch value with a reference value to derive an error signal. The sheets are extracted from the store one by one and a sheet sorting mechanism sorts the sheets into different output stackers. The sorting mechanism includes means responsive to the output of the verifier for segregating the sheets of the batch extracted from the store whenever the error exceeds a predetermined value.

A sheet feeding mechanism in which the sheets in a batch of sheets are to be sorted into different output stackers, comprising means for advancing the sheets along a given path, a buffer store for receiving and temporarily holding a batch of sheets fed along the path while a predetermined batch value is verified, a batch verifier responsive to the passage of each sheet along the path for comparing a measured batch value with a reference value to derive an error signal, means for extracting the sheets one by one from the store, and a sheet sorting mechanism for sorting the sheets extracted from the store into different output stackers, the sorting mechanism including means responsive to the output of the verifier for segregating the sheets of a batch extracted from the store whenever the error exceeds a predetermined value.
A sheet feeding mechanism in which the sheets in a batch of sheets are to be sorted into different output stackers, comprising means for advancing the sheets along a given path, a buffer store for receiving and temporarily holding a batch of sheets fed along the path while the number of sheets in each batch is verified, means for sensing the passage of each sheet along the path to derive a signal representing the number of sheets in each batch, a batch verifier for comparing the measured number of sheets in each batch with a reference value to derive an error signal, means for extracting the sheets one by one from the store, and a sheet sorting mechanism for sorting the sheets extracted from the store into different output stackers, the sorting mechanism including means responsive to the output of the verifier for segregating the sheets of a batch extracted from the store whenever the measured number of sheets in the batch differs from the reference value.
