PURPOSE:To retrieve a desired picture automatically without any error by discriminating the classifications of marks on a recording sheet and inputting the retrieval number of the classification of the desired picture, and then comparing the discrimination result with the input retrieval number. CONSTITUTION:The size of marks on a film is detected by mark sensors 25-28 and then stored in FF circuits 40-42, whose output are applied in combination to the 1st-3rd counters 45-47. Further, intermediate item and small item numbers of picture from input equipment 60 are stored in the 1st-3rd registers 50- 52 according to the operation of switches 61-63, and the outputs of the registers 50 and 52 are supplied to the 1st-3rd comparing circuits 55-57. The outputs of the counters 45-47 are supplied to the circuits 55-57, which compare the mark size from the counters 45-47 with the retrieval numbers inputted from the registers 50-52; when the classification number coincides with the mark size, a classified count signal which corresponds to the desired picture is supplied to a control circuit 60 to prevent malfunction. |
