ABSTRACT:
An automatic removal device of a classifying apparatus has a control circuit which includes a first detector to effect detection as to whether postal matter stacked in a stacking section provided with a removal mechanism is in a removal ready state before a full stack state, and a second detector, which effects detection as to whether the postal matter stacked in the stacking section is in the full stack state. When an empty transport section is brought to a position corresponding to the stacking section during a period from the detection of the removal ready state of the stacked matter in the stacking section before the full stack state to the detection of the full stacked state, or after the detection of the full stack state, these states being detected by the respective switches, the control circuit provides a control signal to a driving device for driving the removal mechanism of the stacking section, whereby the stacked matter in the stacking section is transferred onto the empty transport section.
