Bookbinding apparatus adhesive applicator accurately, briefly controls adhesive temperature to a set value by selecting, in accordance with adhesive initial temperature, one of a plurality of temperature-controller heating modes defining different supply powers and supply durations for supplying power to an adhesive-container heater to control its heating temperature. A sensor detects the temperature of the adhesive in the container at applicator start-up, or on restarting a post-standby applicator. In accordance with the detected temperature, one of the heating modes is selected to heat the adhesive. The applicator warm-up time is thus set in response to the state of the adhesive: If solidified, the adhesive is heated and melted in a maximum supply-power, supply-duration mode; if low-temperature liquefied, it is heated and melted in a second-magnitude supply-power, supply-duration mode; and if the adhesive temperature is high, it is heated and melted in a minimal supply-power, supply-duration mode.

Hot-melt adhesive temperature control method, applicator therefor, and bookbinding apparatus

The present invention provides an adhesive application apparatus that forms a uniform application layer when applying an adhesive to a sheet bundle for a various a length or a width of the sheet bundle. The apparatus includes an applying operation controlling device including a reference value storing device for previously setting and storing a preset reference value of an application length and/or an application width of the sheet bundle, a size recognizing device for identifying an application length and/or an application width of the adhesive applied to the sheet bundle, and an application region comparing device for comparing an identified value of the application length and/or the application width of the adhesive applied to the sheet bundle from the size recognizing device with a preset reference value of the application length and/or the application width of the sheet bundle from the reference value storing device.

Adhesive application apparatus and bookbinding apparatus

Bookbinding-unit adhesive application device that does not interrupt the unit to replenish adhesive when consecutively applying adhesive to sheet bundles, and can shorten the time the system is interrupted. An adhesive storage container () that stores adhesive; an applicator roller () rotatably disposed in the adhesive storage container (); an adhesive supplier () that refills hot-melt adhesive to the adhesive storage container (); heater () that melts the adhesive in the adhesive storage container (); and refill volume controller () that controls the amount of refill adhesive of the adhesive supplier () are provided. The refill volume controller () is configured to set the adhesive refill volume based on information from adhesive detector () disposed in the adhesive storage container (); and remaining sheets determiner () that determines the number of sheets to coat for the sheet bundles to be coated with adhesive.

Adhesive applicator and bookbinder in bookbinding apparatus, and image-forming system associated therewith

In a document feeder, a length of a discharge path from a reading position to a discharge position is longer than a length of a supply path from a feeding position to the reading position. An idling discharge position is disposed, where the distance with the discharge position through the discharge path is shorter than a distance between the feeding position and the reading speed switching position. A control device controls driving of registration rollers, conveyor rollers and discharge rollers simultaneously when a trailing edge of an original reaches the discharge idling position of the discharge path by the discharge rollers while the discharge rollers is stopped. The document feeder efficiently supplies originals sequentially to the reading position, stably reads the image of the original without discharging a previous original during a reading, and aligns and stores the originals in a discharge stacker.

Document feeder for efficiently supplying originals and storing originals in a discharge stacker after reading

First document/image data is printed onto a sequence of sheets that includes sheets of a given size, and sheet(s) of a size that in at least one dimension is larger than the sheets of the given size. At the same time the first document/image data is being printed, second document/image data, i.e., foldout data, is printed onto the outer margin, i.e., a foldout portion, of the sheet(s) of the larger size. The larger-size, foldout sheet(s) is then folded so as to be creased near its overlap with the given-size sheets, and is collated into the sequence of the given-size sheets to form a bundle that is then bound. Thereafter trimming to size the non-bound edge(s) of the bundle slices away the crease in the foldout sheet, leaving the foldout cut-away as an insert tucked into the booklet.
