A paper-like material processing apparatus, comprising: an insert port into which a plurality of paper-like materials can be inserted in a batch; a take-out portion to take out the paper-like materials inserted into the insert port one by one; a conveying path to convey the paper-like materials taken out from the take-out portion; a detector to detect information of the paper-like materials conveyed on the conveying path; first and second stackers (51, 52) to selectively stack the paper-like materials conveyed on the conveying path on the basis of the detection results by the detector; a distributor to distribute the paper-like materials conveyed on the conveying path to either of the first and second stackers (51, 52) on the basis of the detection results by the detector; a single banding portion to band the paper-like materials stacked in the first and second stackers (51, 52); and a conveying mechanism to receive the paper-like materials and convey the paper-like materials to the single banding portion when the number of stacked paper-like materials in the first and second stackers (51, 52) reaches a predetermined number; characterised by a controller to stop taking-out of the paper-like materials by the take-out portion during the conveying operation by the conveying mechanism and to restart taking-out of the paper-like materials by the take-out portion earlier than a stackable time of the paper-like materials into the first and second stackers (51, 52) in correspondence with an end of the banding operation by the single banding portion by a time required to take out the paper-like materials by the take-out portion and convey the paper-like materials to the first and second stackers (51, 52). an insert port into which a plurality of paper-like materials can be inserted in a batch; a take-out portion to take out the paper-like materials inserted into the insert port one by one; a conveying path to convey the paper-like materials taken out from the take-out portion; a detector to detect information of the paper-like materials conveyed on the conveying path; first and second stackers (51, 52) to selectively stack the paper-like materials conveyed on the conveying path on the basis of the detection results by the detector; a distributor to distribute the paper-like materials conveyed on the conveying path to either of the first and second stackers (51, 52) on the basis of the detection results by the detector; a single banding portion to band the paper-like materials stacked in the first and second stackers (51, 52); and a conveying mechanism to receive the paper-like materials and convey the paper-like materials to the single banding portion when the number of stacked paper-like materials in the first and second stackers (51, 52) reaches a predetermined number; characterised by a controller to stop taking-out of the paper-like materials by the take-out portion during the conveying operation by the conveying mechanism and to restart taking-out of the paper-like materials by the take-out portion earlier than a stackable time of the paper-like materials into the first and second stackers (51, 52) in correspondence with an end of the banding operation by the single banding portion by a time required to take out the paper-like materials by the take-out portion and convey the paper-like materials to the first and second stackers (51, 52).
