<P>PROBLEM TO BE SOLVED: To provide an economical monthly calendar utilizing rear surfaces. <P>SOLUTION: When a first H-1 is turned, June is up, and a second H-2 is turned, July-December are displayed. At the end of one year, it can be re-used or discarded as combustible refuse as it is with no classification. 5 sheets are needed including a cover for printing every three months only on the front surface of one sheet. However, 3 sheets are sufficient including the cover by utilizing the front and rear surfaces of sheets in units of 3 months and sheet reduction corresponding to about 40% is possible, which leads to saving corresponding to about 40% and contributes to ecological measures. This ecologization also allows reduction of other sheet-number types. <P>COPYRIGHT: (C)2013,JPO&INPIT |
