Abstract: A bookbinding apparatus for producing a booklet by coating an adhesive onto a back side of a bundle of sheets and by pasting a book cover onto the back side of the bundle of sheets, comprises: an oblique cutout portion forming section to form a cutout on an edge of each sheet of the bundle of sheets in such a way that an oblique cutout portion is formed along the width of the back side of the bundle of sheets; a sheet bundle accommodating section to accommodate the bundle of sheets on which the oblique cutout portion is formed; a coating section to coat an adhesive on the back side of the bundle of sheets accommodated in the sheet bundle accommodating section; and a bookbinding section to paste a book cover on the adhesive-coated back side of the bundle of sheets so as to produce the booklet.

Abstract: A clip binder for holding paper which does not require damaging the material to be held within the clips. The clip binder has a front cover, a binder spine, a back cover and a pair of clips mounted on each end of the binder spine. The clips have a clip spine and two retainer walls which together define the jaws within which the paper is inserted. The clips are positioned perpendicularly to the binder spine such that the jaws face each other and are at right angles to the binder spine. The height of the retainer walls are constructed low so that the papers can be easily leafed through and without and fold back problems. In an alternative embodiment, the clips are slidably mounted to the binder spine. In yet another embodiment, the clips are rotatably mounted to the binder spine.

Abstract: A re-usable examination booklet for the administration of written tests includes overlaid question sheets bound together with the unbound edge of each sheet overlapping the underlying sheet. An answer sheet may be inserted in the booklet beneath the question sheets. Answer areas on the answer sheet are arranged in columns extending along the unbound edges of the question sheets to locate the answer areas in close proximity to the corresponding questions on the question sheets. A modified booklet includes question sheets having openings arranged in columns extending along their unbound edges so that the selected answers can be marked through the openings onto the answer areas of the answer sheet.
