<p>A device for automatically reproducing the contents of a book in sound is disclosed. The device reliably senses an opened page without requiring a manual operation of a user during a page sensing operation. The device is also designed to stably and closely hold the book (30) on a bookstand (10) without allowing the book (30) to undesirably move on the bookstand (10), and to allow the sheets ST1 to ST12 of the book (30) to come into close contact with each other, thus being less likely to create an operational error while sensing an opened page. In the device, the page sensing means (700) consists of a plurality of magnets M1 to M12, each of which is set in each sheet of the book (30), and a plurality of Hall sensors HS1 to HS12 set on the top surface of the bookstand (10) so as to output voltage signals due to a Hall effect when the sensors are affected by the magnetic fields of the associated magnets. The book holding unit is provided on both the top surface of the bookstand (10) and the back cover of the book (30) for preventing the book (30) from being undesirably removed from a designated position on the bookstand (10). The sheet attracting unit is provided on the sheets of the book (30) and the top surface of the bookstand (10) for preventing the sheets from being undesirably opened and preventing the back cover of the book (30) from coming off the top surface of the bookstand (10), and preventing a malfunction of the Hall sensors.</p> |
