[Effect of device]

 The book, which is opened and placed on the book stand 12 of the present invention described above, is stable without lateral displacement because the protruding spine of the book is recessed into the groove 5. Further, the flipping of the opened page can be reliably stopped by the protrusions 2 and 2 and the protrusion shafts 8 and 8.

When the top-side flip-stops 9a, 9b, 9c slide up or down to stop the sliding, the top-side turn-stops 9a, 9b, 9c stay at the stopped position. Therefore, when placing a book on the book stand 12, raise the crease stop A on the top side to a position where the notch D can be hooked up and tilt it sideways, like the conventional crepe stop A on the heaven side. When D is hooked on the upper end of the side plate of the groove 5 and placed high, and when the fold-over stop A on the top side is lowered, raise the fold-out stop A on the top side upright and remove the notch D from the upper end of the groove 5. There is no need to lower it. Also, since the back of the book does not press each part of the top-side cleats 9a, 9b, 9c, the vertical movement of the top-side cleats 9a, 9b, 9c is smoother than the conventional top-side cleats A. , Do not rub the back of the book with the fold-up stoppers 9a, 9b, 9c on the top side.

The top-side cleats 9b and 9c of the embodiment are different from the top-side cleats 9a in that the convex-shaped member 1 has the advantage of the conventional clerk B's top-side cleats A. Lean upwards to turn over the page of the book, tilt the front part of the convex-shaped member 1 forward, and stop the turn-up on the top side. The function of turning over the pages of the book placed on the book stand B is added without turning up and down the flip-out stop A on the top side. In addition, when a book that does not turn open pages is placed, the convex member 1 is tilted upward and the projections 2 and 2 are retracted upward and backward to add a function to make it easier to turn the pages of the book. ing.
