To highly accurately determine matching and mismatching of sealed matters by enhancing thickness measuring accuracy of each of individual forms by minimizing errors of thickness measuring in a sealing and enveloping device.
A barcode 62 of at least a first form of a multiple pieces lot is read by a BCR 13, the multiple pieces lots are superposed on each other to the number of pieces constituted by dividing the multiple pieces lot by a predetermined pieces based on barcode information (at least total number of sheets information), and are accumulated in a detected unit accumulating section 15 as a detecting unit form group 64, the thickness of the detecting unit form group 64 is detected by a first thickness detecting section 17, the detecting unit form group 64 are superposed till forming multiple pieces lot form group 65 of the multiple pieces lot based on the total number of sheet information and are accumulated in the multiple pieces lot accumulating section 19, the thickness information of each of multiple pieces lot is held in a control section, it is determined whether the multiple pieces lot form group 65 is normal by comparing the held thickness information and the total thickness detecting value of the thickness detecting values of the respective detecting unit form groups 64.
