Abstract

PURPOSE: To make the press plate stoppable in the specified angle of inclination and make the opening and closing operations of the press plate smooth by pressing the trough parts of a cam turning together with the press plate by the elastic force of a spring to the roller and stopping the press plate in that turning position.
CONSTITUTION: When a press plate 1 is turned with the horizontal shaft 4 provided to a support shaft 7 as an axis by way of a hinge member 2, a cam 9 provided with holes 9e, 9a of areas larger than the sectional areas of the shafts 4, 8 also turns integrally and the trough part 9c or 9d of the cam 9 contacts the roller 14 of the shaft 7, and this causes the cam 9 to be pressed to the roller 14 by the elastic force of a spring 18 to increase the friction force of the cam 9 and roller 14, as a result of which the press plate 1 in which the moment of rotation is generated by gravity is surely stopped. This constitution permits the sure stopping of the original press- contacting press plate in the desired plural turning positions according to the troughs formed in the cam and permits the smooth opening and closing of the press plate.
