One of Yoshitune Iitsuka's latest patents is a mechanism for engaging portable equipment against a belt clip. This innovative system features a flange-like protrusion on the portable equipment that locks into an engaging part of the belt clip. The design allows for both fitting and removing the portable equipment to be simplified. The flange is constructed from a disc and an annular frame, with inwardly directed protrusions that have slant surfaces. The engaging plate of the belt clip includes a frame and a front plate with a U-shaped recess. The cantilever beam of the engaging plate is defined by a slit, with a claw at the extremity end that also has a slant surface.
