In the present invention, a rear coverof a display part is made of at least a resin material, and a rear coverof an operation part is made of a metal material. Respective plane portions of a front caseof the display part and a front caseof the operation part are made mainly of a metal material, and at least hinge partsand, which are formed on the front caseof the display part and the front caseof the operation part, are made of a resin material.

A front case at a display section side of frame shape is formed of metal material having strength and a bathtub-shaped draw frame formed by drawing metal plate is fixed at the external side of the front case at the display section side by heat adhesive to be integral with the front case at the display section side. Two L-shaped frames formed by bending metal plate materials are fixed at the internal side of the front case at the display section side by two heat adhesives to be integral with the front case at the display section side. The front case at the display section side, the two L-shaped frames, and the bathtub-shaped draw frame are integral with each other to have sandwich structure.

An upper case of the display section includes a first connecting portion having a cylindrical hole, into which an inner cylinder of a dummy hinge composed of two cylindrical portions having the same axis and different diameters is inserted rotatably, wherein the first connecting portion protrudes from an end of the upper case. An upper case of the keybutton section includes a second connecting portion located, along a hinge axis, on the center side of the first connecting portion, and having a cylindrical hole into which an outer cylindrical portion of the dummy hinge is inserted unrotatably, wherein the second connecting portion protrudes from an end of the upper case. The hinge structure comprises a stopper for fixing the dummy hinge, which can be inserted as the dummy hinge is buried in the cylindrical hole, with the inner cylindrical portion inserted into the cylindrical hole of the first connecting portion.

A structure for mounting a slide knob included in, e.g., a portable apparatus is disclosed. The structure of the present invention allows a slide knob to be mounted to the apparatus without resorting to screws and therefore reduces the number of assembling steps and the number of parts.

Slide knob mounting structure

To anchor a chain clip to the casing of a radio pager, a generally C-shaped plastically deformable metal fitting has its opposite ends rotatably fitted in a hole formed in the casing. The metal fitting is fully received in a recess also formed in the casing when rotated about the hole to a position substantially flush with the surface of the casing. When the chain clip is used, the metal fitting is pulled out of the recess, and then the chain clip is anchored to the fitting.
