AI Technical Summary
Conventional paper notebooks are limited in their ability to store documents without distorting the binding and are cumbersome when carrying multiple items, with documents often slipping out, and date checking is difficult.
A strong paper accordion band is integrated into the notebook spine, with processed envelopes glued to its pages, allowing documents to be stored in an unfolded state, accommodating increased storage capacity and preventing binding distortion.
The solution enables efficient storage of documents in an open state, accommodating more items without distorting the notebook binding, and facilitating easy date recording and retrieval.

Abstract
Description
[Technical Field]
[0001] This invention relates to a bellows notebook with a customizable envelope, which allows you to write the date and details of the process on the relevant page of the notebook when you receive mail or documents, and then you can customise the empty envelope (hereafter referred to as a customised envelope) on that page, allowing you to freely place documents in it. The envelope can also be stored open, which has the advantage of making it easy to see and take out. [Background technology]
[0002] Until now, when I received mail or other items, I would write down how to handle them in a notebook, and then file away any documents on that page, and later find that page, check it, and take any necessary action. However, because notebooks are not originally intended to be stored by pinching or folding, if documents are simply bound in, the pages will swell, putting strain on the notebook's stitched binding and causing it to become distorted, which places a limit on how much can be bound in. [Prior art documents]
[0003] [Patent Document 1] At the end of 2022, the Japan Patent Office conducted a survey of "accordion envelopes" and found about 85 examples, but could not find any "similar" or "applicable" items. Summary of the Invention [Problem to be solved by the invention]
[0004] Conventional paper notebooks were primarily used for writing, and at most, they could only hold a few documents in them. If you tried to fit too many mail or documents in them, the binding would become distorted, they were difficult to carry around, and documents would slip out, so there were limitations to them. Furthermore, there were many cases where it became difficult to check the date, etc. The present invention was invented to solve these problems. [Means for solving the problem]
[0005] A strong paper accordion band (3) is set inside the spine (2) of this notebook, and the left side of each page (4) is glued to it in a strip shape. Envelopes or the like are recycled and processed and glued in strips to the accordion band (3) of the page (hereinafter referred to as processed envelopes (large, medium)), so that documents can be stored in an unfolded state in the processed envelopes (large, medium). The modified envelope post-attached accordion notebook is configured as described above. [Effects of the Invention]
[0006] By using this invention, when receiving a lot of mail, documents, etc. on a daily basis, the date and necessary information can be written on the pages of the accordion notebook behind this processed envelope, and documents that need to be kept can be stored in an open state in the processed envelopes (large and small) (7, 8) installed in the lower half, and even if the sandwiched part swells, it can accommodate the storage amount.

[0008] Hereinafter, an embodiment of the present invention will be described. (a) Attach the accordion band (3) to the body (1) just inside the spine (2) by connecting the front cover (5) and back cover (6). (b) Spread out the accordion band (3) and attach all of the pages (4). Then, similarly, glue the processed envelope (7 or 8) onto the bottom left corner of the page (4). (c) Cut the large envelope (Diagram 5) in half diagonally and glue the left edge of each of the top and bottom sheets to the page. For other envelopes, such as inner envelopes (Diagram 6), lay them horizontally and cut open the top, reusing the envelope in the same way. [Explanation of symbols]
