Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
54 words
A lens barrel comprising: (a) an electromagnetic drive motor mounted on a stationary portion of said lens barrel; and (b) a vibration-proof member for preventing vibrations of said motor, said vibration-proof member wrapping the outer periphery of said motor and having holding portions for fixing the lead wires for power supply to said motor.
Claim 2
Dependent Claim
54 words
A lens barrel comprising: (a) an electromagnetic drive motor mounted on a stationary portion of said lens barrel; and (b) a vibration-proof member for preventing vibrations of said motor, said vibration-proof member wrapping the outer periphery of said motor and having holding portions for fixing the lead wires for power supply to said motor.
Claim 3
Dependent Claim
48 words
A lens barrel comprising: (a) an electromagnetic drive motor; (b) a vibration-proof member for preventing vibrations of said motor, said vibration-proof member having a ring form made of an elastic material and the inner surface of said ring having grooves for holding the lead wires of said motor.
Claim 4
Dependent Claim
48 words
A lens barrel comprising: (a) an electromagnetic drive motor; (b) a vibration-proof member for preventing vibrations of said motor, said vibration-proof member having a ring form made of an elastic material and the inner surface of said ring having grooves for holding the lead wires of said motor.
Claim 5
Dependent Claim
141 words
A lens barrel comprising: (a) a stationary cylinder constituting part of said lens barrel; (b) a diaphragm device; (c) a stepping motor for driving said diaphragm device, said stepping motor comprising a stator and a rotor which are formed to a hollow core cylindrical shape with an aperture opened so as to pass an image bearing beam at the centeral portion of said rotor; and (d) a vibration-proof member for preventing vibrations of said motor, said vibration-proof member being made of a vibration absorbable material, being formed to a cylindrical shape, when said motor is fixedly mounted in the inner diameter of said stationary cylinder being positioned between said stator and said stationary cylinder so as to wrap the outer periphery of said stator, and further said cylindrical vibration-proof member having grooves for accommodation of the lead wires of said motor.
Claim 6
Dependent Claim
141 words
A lens barrel comprising: (a) a stationary cylinder constituting part of said lens barrel; (b) a diaphragm device; (c) a stepping motor for driving said diaphragm device, said stepping motor comprising a stator and a rotor which are formed to a hollow core cylindrical shape with an aperture opened so as to pass an image bearing beam at the centeral portion of said rotor; and (d) a vibration-proof member for preventing vibrations of said motor, said vibration-proof member being made of a vibration absorbable material, being formed to a cylindrical shape, when said motor is fixedly mounted in the inner diameter of said stationary cylinder being positioned between said stator and said stationary cylinder so as to wrap the outer periphery of said stator, and further said cylindrical vibration-proof member having grooves for accommodation of the lead wires of said motor.
