Classifying apparatus with automatic removal device

Claim 1

A classifying apparatus with automatic removal device comprising: (a) means for reading out classifying information provided on matter such as sheets to be classified; (b) a plurality of stacking sections arranged in a plurality of rows extending one above another each provided with a take-out mechanism; (c) means for distributing the matter to be classified to said plurality of stacking sections according to classifying information from said reading means; (d) a transport section driven to successive positions corresponding to said respective stacking sections and receiving the distributedly stacked matter from said stacking section; (e) means for detecting whether the distributedly stacked matter in said stacking section is in a removal ready state before a full state or in the full stack state; (f) control means for providing a control signal when the empty transport section is brought to a position corresponding to said stacking section during a period from the detection of the removal ready state of the stacked matter in said stacking section before the full stack state to the detection of the full stack state, or after the detection of the full stack state, these states being detected by said detecting means; and (g) driving means operatively connected to said control means to receive said control signal therefrom, said driving means for driving the removal mechanism of said stacking section in response to the control signal from said control means such that said stacked matter is transferred onto said empty transport section.
