The belt driving device of the present invention has left and right frames (5, 15) which upper ends are connected by a slide bed (16), an endless belt (20) being latched by a head pulley (21) which is disposed on a head end of frames (5, 15) and a tail pulley (21) disposed on a tail end thereof, and an actuator unit (12) of the belt detachably mounted on the frame under side. A drive pulley (30) is disposed in the actuator unit (12) and is supported by a frame body with a rubber spring so as to contact with an outer surface on the return side belt and inner pulleys (23, 24) are disposed on the frame under side at the actuator unit attaching position so as to contact with the return side belt inner surface. The drive pulley (30) is always pressed and energized to the inner pulley side by the rubber spring and the belt supported between the inner pulley and the drive pulley (30) is friction actuated by pressing the drive pulley from the belt outside. The take-up device can be eliminated from the device by pressing the drive pulley to the belt side.
