PURPOSE:To eliminate the extra bottles and to eliminate the blank paper when binding a book, by setting a concentration detection sensor to a relaying tray, storing the blank paper into a bin of the preceding copy or into the next bin and at the same time displaying the storage of the blank paper. CONSTITUTION:A relaying tray 9 sores temporarily the sheet with which the 1st surface is recorded. A concentration detection sensor 15 is set between the tray 9 and a transcription part 5. The piled paper fed on the tray 9 is divided into each sheet through a paper loosening process. In this case, the blank paper is detected by the sensor 15. The detected blank paper is stored into a bin containing the preceding normal copy or into the next bin by means of the paper detection sensors 13g, 13j, 13m, etc. This storage of the blank paper is displayed by the light emitting diodes 18a-18t. As a result, the extra bins are excluded for the blank paper. Furthermore the blank paper can be excluded when binding the paper into a book. |
