Vertical folding notebook

Abstract

This product is a vertically opening folding notebook designed for recording relatively short texts, such as Buddhist scriptures like the Heart Sutra, allowing for a rhythmic reading experience while maintaining ease of use. As shown in the front view, this vertically opening folding notebook has a vertical shape with the longer side running vertically and the shorter side running horizontally. As shown in the perspective view, the vertically opening folding notebook 1 has the front cover at the top and the back cover at the bottom, with accordion-folded paper sandwiched between the front and back covers. As shown in the reference perspective view 1 showing the state of use, this vertically opening folding notebook 1 opens vertically along the shorter side. When writing characters, such as hiragana, in the vertically opening folding notebook 1, they should be written vertically along the longer side, as indicated by the circle in the reference perspective view 1 showing the state of use. When a user turns the pages of the vertical folding notebook 1, they open the front cover 2 in the direction of the arrow shown in the reference perspective diagram 1 representing the state of use, starting from the state of the vertical folding notebook 1 shown in the perspective view, and then turn the pages 4 sequentially in the direction of the arrow. By turning the pages of the vertical folding notebook 1 in this way, the user can move to the next page. When all the pages have been turned, the back of the back cover 3 will be visible. Therefore, if the back cover 3 is turned in the direction of the arrow shown in the reference perspective diagram 1 representing the state of use, the back cover 3 will be visible. This state is the vertical folding notebook 1 shown in the perspective view with its top and bottom directions reversed. From this state, the user continues to turn the back cover 3 in the direction of the arrow shown in the reference perspective diagram 1 representing the state of use. Reference perspective diagram 2 representing the state of use is a perspective cross-sectional view of the vertical folding notebook 1, showing the state with the back cover 3 open. In the reference perspective view 2, which shows the state of use, the vertical folding notebook 1 is upside down vertically, and unlike the vertical folding notebook shown in reference perspective view 1, the back cover 3, which has been flipped over to show the accordion-folded paper 4, is positioned away from the front cover 2. If you continue to flip over the paper 4 in the direction of the arrow from this state, you will eventually flip over the front cover 2. Once the front cover 2 is flipped over, it returns to the state of the vertical folding notebook shown in the perspective view. Because it is designed to be flipped over in this way, the vertical folding notebook is made to a size that can be held in one hand by the user.
