Faulty bookbinding due to sheet-size, etc. setting errors when bundle-collated inner-leaf sheets and coversheets they are bound with are placed in respective trays is stopped before it occurs. In an inner-leaf tray and a coversheet tray: (1) sheet sensors are disposed, and when both detect sheet presence, the inner-leaf sheets are transported to an adhesive-application location, and (2) sheet-side detection sensors or (3) sheet length and width detection sensors are disposed, and in either case when from the detection information predetermined encased booklet formation is impossible, device startup is halted. Width detectors are disposed in the inner-leaf and coversheet trays for detecting opposing sides of sheets stacked therein, and a controller is configured to convey into the device interior inner-leaf sheets from the inner-leaf tray when predetermined encased booklet formation is possible with the inner-leaf sheets and coversheets.
