<p>PROBLEM TO BE SOLVED: To obtain a method which can prevent cellular phones from naturally slipping off even when they are inverted while facilitating the viewing of a display screen by allowing the wearing thereof on a waist belt or the like free from hampering sitting while enabling concurrent application thereof on arms with a simple operation of loading thereof into or unloading thereof from a housing case. SOLUTION: In the natural slip-off prevention method wherein the housing case is linked to an accessory strap of a telephone set with a loading/unloading type link device, as shown in Fig. 1, the link device 2 is mounted on a surface part of the housing case 1 and the accessory strap 3 of the telephone set is made additionally stretchable to mount a mating means 4 at the tip thereof. As shown in Fig. 3, the housing case 1 is so formed as to get the upper end part thereof on the side of the screen exposed when the telephone set is mounted. Otherwise, it may be a slender insertion ring with both ends of the telephone set exposed. The housing case is applied on the waist belt in a laterally insertable fashion or on the arm belt in a vertically insertable fashion to be used for daily carrying goods properly in a vertical or horizontal way. Moreover, it mat be rotatable on the belts.</p> |
