Abstract

Abstract An assembly of electronic apparatus housed in a case is assembled so that a pair of opposed panels associated with the case are integrally connected through a circuit board. Pillar-like portions having guide grooves and engaging shoulders associated therewith are projectingly provided on each of the panels. The circuit board is formed with engaging portions which are inserted into the guide grooves and which come into abutment with the engaging shoulders for removal engagement. The pillar-like portions are subjected to elastic distortion as the engaging portions are inserted into the guide grooves. The pillar positions resiliently return to their original state and bring the engaging shoulders into abutment with the engaging portions.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 189 words
An assembly having electronic apparatus housed in a case having openings at both ends, comprising; a pair of panels having a configuration corresponding to the configuration of said case openings, each panel having four pillar-like portions which are projectionly provided one on each of the four corners of the panel surface; said each pillar-like portion having a guide groove and an engaging shoulder; circuit boards, composed as a part of said electronic apparatus, integrally connecting said panels, each circuit board having engaging portions at four corners which are engagedly inserted into said pillar guide grooves and which come into abutment with said engaging shoulders for engagement; said pillar-like portions being subjected to elastic distortion as said engaging portions are inserted into said guide grooves and resiliently returing to their original state to bring said engaging shoulders into abutment with said engaging portions when said engaging portions are fully inserted into said guide grooves; and said circuit boards and panels are inserted and housed in said case, whereby said panels cover said case openings and provide surfaces for mounting display panels, controls and/or external terminals of said electronic apparatus, respectively.
Claim 2
Dependent Claim 189 words
An assembly having electronic apparatus housed in a case having openings at both ends, comprising; a pair of panels having a configuration corresponding to the configuration of said case openings, each panel having four pillar-like portions which are projectionly provided one on each of the four corners of the panel surface; said each pillar-like portion having a guide groove and an engaging shoulder; circuit boards, composed as a part of said electronic apparatus, integrally connecting said panels, each circuit board having engaging portions at four corners which are engagedly inserted into said pillar guide grooves and which come into abutment with said engaging shoulders for engagement; said pillar-like portions being subjected to elastic distortion as said engaging portions are inserted into said guide grooves and resiliently returing to their original state to bring said engaging shoulders into abutment with said engaging portions when said engaging portions are fully inserted into said guide grooves; and said circuit boards and panels are inserted and housed in said case, whereby said panels cover said case openings and provide surfaces for mounting display panels, controls and/or external terminals of said electronic apparatus, respectively.
Claim 3
Dependent Claim 29 words
An assembly according to claim 1 wherein said guide groove of each of said pillar-like portions is a crossed guide groove provided along the length of said pillar-like portions.
Claim 4
Dependent Claim 33 words
An assembly according to claim 1 wherein said engaging shoulder of said pillar-like portions formed on one of said pair of panels is formed by cutting a base portion of said pillar-like portions.
Claim 5
Dependent Claim 33 words
An assembly according to claim 1 wherein said engaging shoulder of said pillar-like portions formed on one of said pair of panels comprises a window in the guide groove of each pillar-like portion.
Claim 6
Dependent Claim 67 words
An assembly according to claim 1 wherein said engaging portions of said circuit boards have a width set somewhat larger than the spacing between opposing guide grooves of each of said pillar-like portions, and four corners of said circuit boards are cut into a tapered configuration in an inserting direction and have a stepped portion engaged by said engaging shoulder in the state where insertion is completed.
Claim 7
Dependent Claim 51 words
An assembly according to claim 1 wherein one side of one of said pair of panels has a first engaging portion, said case being formed with a second engaging portion complemental to said first engaging portion, and said first and second engaging portions being brought into springing engagement with each other.
