To realize a machine for turning over pages which can surely perform the operation of turning over pages by simplifying the operation of turning over pages and its control means.

A reading desk includes a tool for turning over pages, in which tilt-supporting device is attached to the pole stood in the vicinity of the top side of the openable face binding groove of a book, allowing the tilt-supporting device to support a small vertical type motor in a rightward tilting position or a leftward tilting position, the motor is set in a clockwise rotation direction or a counter-clockwise rotation direction in each support position, an arm reaching the midway of the openable face is pivotably supported like a cantilever on the output side above the motor, and a rubber piece having a high elasticity and a large friction coefficient with a paper sheet to be turned over is tilted at the tip end of the arm, a bar letter-shaped string member is horizontally provided in an intersecting manner below the midway of the arm, and an arcuate semi-circle reaching the top side margin part of the operable face from the opposite ends of the member is tilted. A slope of a wedge-shaped piece is projectingly provided above the inter-connection between the rotating channel of the rubber piece and the top of the operable face.
