If the user wants to read the next page after reading all the sentences of the open page, repeating the above-described process, the user can continue reading by turning the right bookcase to the left.

When the user wants to turn the left bookshelf to the right, the user inputs a signal to rotate the rotational track 181 in a counterclockwise direction, and detects it by the detection unit 151 and applies it to the controller 153. Accordingly, the control unit 153 drives the motor 186 in the opposite direction as in the above description, whereby the rotation trajectory 181 rotates in the counterclockwise direction. At this time, the elastic contact mechanism 110 passes through the front of the book holder 120 and contacts the surface of the left bookshelf BP to turn over the left bookshelf BP to the right, and the pusher mechanism 170 on the left that follows the right side is right. Push the back of the bookcase (BP) to the right. In addition, the locking jaw 190 installed on the upper rotational track 181 operates the bookcase pressing holes 140 installed on the right edge. The rest of the process is the same as that described above, but in the opposite direction. This process can be used to return the right bookcase to the right when it is exceeded by more than one bookcase to the left. The opposite is also true.
