Claims

[Claims for Utility Model Registration] A display device that displays characters, figures, etc. on the surface of a cathode ray tube, and a mounting surface for attaching the display device to the upper end;
A boss having a threaded portion on the inner circumferential surface at the center of the lower surface of this mounting surface, an upper fixing base having a side plate facing across the boss and having an arcuate lower side, and corresponding to the shape of the lower side of the side plate. and a lower fixing base having an elongated hole in the bottom surface of the recess that engages with the boss, and the boss of the upper fixing base is engaged with the elongated hole of the lower fixing base. At the same time, both side plates are fitted into the recesses, and both fixing bases are fixed by fastening the mounting screws to the bosses from the bottom side of the lower fixing base through the retaining plates.When the display is moved, the boss of the upper fixing base In the variable elevation angle mechanism for a display device, in which the display device is moved in the longitudinal direction within the elongated hole of the lower fixing base, the side plate slides along the recessed surface, and the display device is fixed by the fixing means at an arbitrary elevation angle that is easy for the operator to see. A steel plate is attached to the outer surface of the side plate of the upper fixed base, and a magnet is embedded in the inner surface of the recess of the lower fixed base that faces the iron plate, and the magnet moves within the recess due to the attraction force between the iron plate and the magnet. A variable elevation angle mechanism for a display device, characterized by using a fixing means for fixing a side plate.
