Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
74 words
A vibration absorption apparatus for an object driven in reciprocating motion comprising: an endless belt; moving means connected to said endless belt, said object being connected to said endless belt for driven motion by said moving means over one path of reciprocation; and a counterweight member connected to said endless belt for driven motion in a direction opposite to said object over another path of reciprocation parallel to said one path of said object.
Claim 2
Dependent Claim
74 words
A vibration absorption apparatus for an object driven in reciprocating motion comprising: an endless belt; moving means connected to said endless belt, said object being connected to said endless belt for driven motion by said moving means over one path of reciprocation; and a counterweight member connected to said endless belt for driven motion in a direction opposite to said object over another path of reciprocation parallel to said one path of said object.
Claim 3
Dependent Claim
30 words
A vibration absorption apparatus as in claim 1, wherein the mass of said counterweight member is substantially equal to or smaller than the mass of said object to be reciprocated.
Claim 4
Dependent Claim
29 words
A vibration absorption apparatus as in claim 1, wherein the movement speed of said counterweight member is substantially equal to the movement speed of said object to be reciprocated.
Claim 5
Dependent Claim
28 words
A vibration absorption apparatus as in claim 1, wherein means for moving said counterweight member is the same as the means for moving said object to be reciprocated.
Claim 6
Dependent Claim
38 words
A vibration absorption apparatus as in claim 1, wherein said object to be reciprocated is a carriage which carries thereon a reading head and record for use in facsimile apparatus, and said counterweight member is a balance weight.
Claim 7
Dependent Claim
86 words
A reading and recording apparatus for a facsimile machine comprising: a read head and a record head mounted on a carriage for reciprocating motion; and endless belt; moving means connected to said endless belt, said carriage being connected to said endless belt for driven motion by said moving means over one path of reciprocation; and a counterweight member connected to said endless belt for driven motion in a direction opposite to said carriage over another path of reciprocation parallel to said one path of said carriage.
Claim 8
Dependent Claim
86 words
A reading and recording apparatus for a facsimile machine comprising: a read head and a record head mounted on a carriage for reciprocating motion; and endless belt; moving means connected to said endless belt, said carriage being connected to said endless belt for driven motion by said moving means over one path of reciprocation; and a counterweight member connected to said endless belt for driven motion in a direction opposite to said carriage over another path of reciprocation parallel to said one path of said carriage.
Claim 9
Dependent Claim
49 words
A reading and recording apparatus as in claim 6 wherein said read head has read elements aligned in one direction normal to the direction of reciprocation of the carriage, and said record head has recording styli aligned in another direction normal to the direction of reciprocation of the carriage.
