An upper case and a lower case are fixed without using screws so that assemblage workability is improved. An electric appliance can be divided into plastic upper case, metal-plate-made lower case, and logic package having print substrates. As a result, the electric appliance is easy to make.

Electric appliance, its assembling method, and its housing structure

An upper case 1 and a lower case 2 are fixed by no screw, so that assemblage workability is improved. An electric appliance can be divided into plastic upper case 1, metal-plate-made lower case 2, and logic package 9 having print substrates. As a result, the electric appliance is easy to waste.

An electric appliance includes a case, an accommodation portion for accommodating a liquid crystal indicator, and upper and lower protrusions respectively arranged above and below an opening provided on stepped portion not arranged on the front face portion of the accommodation portion. The liquid crystal indicator engages with the upper protrusion and mounts on the lower protrusion such that the liquid crystal indicator is positioned adjacent to the stepped portion and is visible through the opening.

A housing structure of an electric appliance has an upper case and a lower case. The upper case is provided with a plurality of logic holding portions arranged on inner sides of left and right side face portions of the upper case. An interior one of the logic holding portions has a protrusion engagement portion which is defined by a slant face and a front face of the interior holding portion. The lower case is provided with a lower case side engagement portion which engages releasibly with the protrusion engagement portion. The lower case side engagement portion has a resilient half portion in a half support which is formed on a bottom face of the lower case and on which an extrusion portion that engages releasibly with the protrusion engagement portion and a threaded hole for a screw are formed. The housing structure is disassembled by screwing the screw into the threaded hole so that the screw's end portion contacts slidably with the slant face of the interior logic holding portion so as to move the resilient half portion downwardly away from the upper case to thereby release the engagement of the extrusion portion from the protrusion portion.
