Abstract

Abstract An apparatus for classifying sheet-like written material by transporting a series of sheet-like written pieces one by one of a passageway and collecting them in those of the pockets provided therein which correspond to the classification codes indicated on the surface of sheet-like written pieces characterized in that the apparatus comprises a device for supplying data designating the pockets in which particular sheet-like written pieces are to be collected; a device for furnishing data on the current position of the written pieces traveling on the passageway; a memory device consisting of a plurality of sections to be stored with data designating the pockets associated with the written pieces transported on the passageway and data on the current position of said written pieces, a device for replacing first or already stored data on the current position of the written pieces by second or fresh data on their subsequent positions being obtained by further transit; and a device for comparing the stored pocket-designating data with fresh data on the subsequent position of the written pieces and, when a prescribed coincidence is detected to exist between both data, collecting particular written pieces in properly designated pockets.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 132 words
AN APPARATUS FOR CLASSIFYING SHEET-LIKE WRITTEN MATERIAL BY TRANSPORTING A SERIES OF SHEET-LIKE WRITTEN PIECES ONE BY ONE ON A PASSAGEWAY AND COLLECTING THEM IN POCKETS PROVIDED THEREIN WHICH CORRESPOND RESPECTIVELY TO A CLASSIFICATION CODE INDICATED ON THE SURFACE OF A SHEET-LIKE WRITTEN PIECE, CHARACTERIZED IN THAT THE APPARATUS COMPRISES MEANS FOR SUPPLYING DATA DESIGNATING THE POCKET IN WHICH A PARTICULAR SHEET-LIKE WRITTEN PIECE TRAVELLING ON THE PASSAGEWAY IS TO BE COLLECTED, MEANS FOR. SUPPLYING A CURRENT POSITION OF A SHEET-LIKE WRITTEN PIECE WHICH MEANS INCLUDES A PLURALITY OF DETECTORS EACH CORRESPONDING TO EACH OF THE POCKETS AND DISPOSED ALONG THE PASSAGEWAY OF THE TRAVELING WRITTEN PIECE AND SUPPLIES DATA ON ITS CURRENT POSITION, A MEMORY DEVICE CONSISTING OF AT LEAST AS MANY STORING SECTIONS AS WRITTEN PIECES JOINTLY TRAVELLING ON THE

Claim 3
Dependent Claim 52 words
A written material-classifying apparatus according to claim 1 wherein the means for supplying pocket-designating data includes a unit for reading out the classification data indicated on the surface of a written piece and a first code converter for converting the readout classification code into a logical code signal designating a prescribed pocket.
Claim 4
Dependent Claim 65 words
A written material-classifying the apparatus according to claim 1, wherein the means for supplying data on the current position of a traveling written piece includes a detector for generating a detection signal when the written piece shuts off a light path of the detector and a second code converter for converting the detection signal into a logical code signal denoting the position of the detector.
Claim 5
Dependent Claim 67 words
A written material-classifying apparatus according to claim 1, wherein the sections of the memory device are each stored with pocket-designating data and a busy signal indicating whether or not the section is actually used with a traveling written piece and, after the written piece is received in the designated pocket, having the already stored data cleared ready to be supplied with fresh data on another traveling piece.
Claim 6
Dependent Claim 58 words
A written material-classifying apparatus according to claim 1, wherein the written material passageway consists of a main course and a plurality of branch courses each having a plurality of pockets arranged therein, and the pocket-designating data and data on the current position of a traveling written piece respectively include data on the specified one of said branch courses.
