Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
126 words
An electronic clock movement structure comprising: gear train combination in which sets of gear trains are held among plural supporting plates at predetermined distances; a lower case holding said gear train combination; a circuit base plate arranged to be attached to said lower case and said supporting plates; resilient contact plates facingly arranged to conductive portions of said circuit base plate; an upper case fixed to said lower case and including pressing portions which engage with said contact plates; and said electronic clock movement structure being characterized in that attachment of said upper case to said lower case applies pressure to said contact plates to electrically connect said contact plates with said circuit base plate and holdingly attach said gear train combination to said lower case.
Claim 2
Dependent Claim
126 words
An electronic clock movement structure comprising: gear train combination in which sets of gear trains are held among plural supporting plates at predetermined distances; a lower case holding said gear train combination; a circuit base plate arranged to be attached to said lower case and said supporting plates; resilient contact plates facingly arranged to conductive portions of said circuit base plate; an upper case fixed to said lower case and including pressing portions which engage with said contact plates; and said electronic clock movement structure being characterized in that attachment of said upper case to said lower case applies pressure to said contact plates to electrically connect said contact plates with said circuit base plate and holdingly attach said gear train combination to said lower case.
Claim 3
Dependent Claim
70 words
The electronic check movement structure according to claim 1, wherein said contact plates include fixing portions which are interposed to be fixed between said circuit base plate and said upper case, arms resiliently extending from said fixing portions and contact tongues provided in the end of said arms which are pressingly in contact with the said conductive portions on said circuit base plate by resilient force of said contact plates.
Claim 4
Dependent Claim
72 words
The electronic clock movement structure according to claim 1 or 2, wherein said circuit base plate attaches to one supporting plate, sets of gear train are supported between two supporting plates, another supporting plate attaches to said lower case, the other sets of gear train are supported between said another supporting plate and said gear train combination is held by means of pressing to fix said upper case to said lower case.
