Abstract

PURPOSE:To prevent mischief and enhance the degree of design performance due to omission of decoration screws, by allowing the inner side of a face plate to bear swingable latchs, which are detained with a pawl at the side of a case to restrain swings of the face plate. CONSTITUTION:A locking mechanism 10 is disengaged, and a hinged door 9 is opened. When an operational lever 22 is pulled to the right, a plurality of latches 15 swing against the action of a tensile spring to disengage detention of their hook parts with pawl members, and thus a face plate 4 is allowed to swing. Then the latches 15 are put in contact with a stopper 17 and located through the recovering action of the tensile spring. If this face plate 4 is pushed by hand to a case 2, the tips of a plurality of latches 15 contact a plurality of pawl members, and then hook parts are detained with pawl members 12 to generate fast fixation of the face plate 4 to the case 2. As the latches 15 to restrain swings of the face plate 4 are installed on the inner side of the face plate 4 which is visible, use of any screw seat and decoration screws can be omitted.
