Book support for keeping book open

A book support, comprising:

• a stand (120) having a predetermined length in a width direction of a book spine, and being configured to support the book spine in such a manner that the book spine does not rotate in a process of turning pages of the book;
• and
• a pin-shaped pressure rod (140) of which one end is coupled with the stand (120), the pressure rod being configured to be spaced in a predetermined gap from the stand (120) in a length direction of the book spine, so as to allow the pressure rod (140) to be sandwiched between open pages of the book with pressing the book spine, and to have a thickness to inhibit turned pages of the book from returning back to original positions thereof when the pages have been turned in a state that the pressure rod (140) is sandwiched between the pages,
• wherein when the stand (120) is put on a floor in a state that certain pages of the book are opened and the pressure rod (140) is sandwiched between the open pages of the book, the stand (120) is supported by the floor in the process of turning the pages, inhibiting rotation of the book spine and also maintaining the turned pages as they are turned, thereby enabling a reader to read the book while turning the pages in a state that the pressure rod (140) is positioned between the open pages of the book.
