BOOKLET HAVING CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a connection structure for booklets which can connect the booklets to one another in a closed stack state and can suppress cost of manufacture.SOLUTION: A notch 5 is vertically formed in a front cover sheet 3 of each booklet 1 thereby forming a slit 7. Further, a notch 5 is formed in a back cover sheet 9 thereby forming an insertion extention piece 11. The insertion extention piece 11 is inserted in the slit 7 and is extended, thereby connecting the booklets 1. The insertion extension piece 11 is configured from an insertion part 13 and an extension part 15. The extension parts 15 are so formed on both sides of a stem of the insertion part 13 as to be able of being folded. A position of the slit 7 and a position of a width 17 of the stem of the insertion part 13 are overlapped at a same position in a stack state of the booklets 1 for the purpose of connection of the booklets 1.
