Abstract
Abstract A cleaner apparatus by which flaws or dust on the surface of a disk can be removed readily to prevent otherwise possible disorder in audio or video signals to be reproduced from the disk to allow utilization of the disk for a long interval of time is provided. The cleaner apparatus comprises an arm 1 for removably holding a disk 5 for rotation thereon, a dust or flaw removing rotary member 2 having a cylindrical peripheral face for being resiliently contacted with the surface of the disk 5, and a driving source 3 for driving the rotary member 2 to rotate around an axis of the same.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
240 words
A cleaner apparatus comprising: a casing; an arm pivotably connected at one end to said casing; holder means connected to another end of said arm and for rotatably holding a disk; a cylindrical cleaning member connected to said casing and positioned to resiliently contact a surface of the disk, said cylindrical cleaning member having a longitudinal axis spaced from, and substantially parallel to, a radial axis of the disk; driving means for rotating said cleaning member about said longitudinal axis; a cam motor positioned in said casing said cam motor having an output shaft; a cam mounted on said output shaft; a cam follower mounted on said arm and positioned in contact with said arm, said cam follower, said cam and said cleaning member cooperating with each other to cause rotation of said cleaning member to bias said cam follower and said arm against said cam, said cam motor rotating said output shaft to rotate said cam, rotation of said cam causing a force against said cam follower substantially opposite to said bias caused by said cleaning member, said cam and said cam follower cooperating to cause said force to move said cam follower and said arm to pivot about said one end of said arm connected to said casing, pivot movement of said arm moving the disk connected to said holder means in a rocking movement against said cleaning member to perform a wiping out operation on the disk.
Claim 2
Dependent Claim
240 words
A cleaner apparatus comprising: a casing; an arm pivotably connected at one end to said casing; holder means connected to another end of said arm and for rotatably holding a disk; a cylindrical cleaning member connected to said casing and positioned to resiliently contact a surface of the disk, said cylindrical cleaning member having a longitudinal axis spaced from, and substantially parallel to, a radial axis of the disk; driving means for rotating said cleaning member about said longitudinal axis; a cam motor positioned in said casing said cam motor having an output shaft; a cam mounted on said output shaft; a cam follower mounted on said arm and positioned in contact with said arm, said cam follower, said cam and said cleaning member cooperating with each other to cause rotation of said cleaning member to bias said cam follower and said arm against said cam, said cam motor rotating said output shaft to rotate said cam, rotation of said cam causing a force against said cam follower substantially opposite to said bias caused by said cleaning member, said cam and said cam follower cooperating to cause said force to move said cam follower and said arm to pivot about said one end of said arm connected to said casing, pivot movement of said arm moving the disk connected to said holder means in a rocking movement against said cleaning member to perform a wiping out operation on the disk.
Claim 3
Dependent Claim
26 words
An apparatus in accordance with claim 1, further comprising: means for pivoting said arm about an axis substantially parallel to an axial axis of the disk.
Claim 4
Dependent Claim
20 words
An apparatus in accordance with claim 1, wherein: said cleaning member is formed from a plurality of layers of cloth.
Claim 5
Dependent Claim
53 words
An apparatus in accordance with claim 3, wherein: said layers of cloth are substantially circular and have an outer periphery side, said layers of cloth being sewn from a central portion toward an outer periphery to form a fixing portion with said outer periphery side of said layers of cloth being not sewn.
Claim 6
Dependent Claim
38 words
An apparatus in accordance with claim 1, wherein: said driving means includes a shaft; said cleaning member is mounted on a pipe and said pipe is designed to be repetitively mounted on said shaft of said driving means.
Claim 7
Dependent Claim
48 words
An apparatus in accordance with claim 1, wherein: said driving means includes a shaft; said cleaning member includes a sheet mounted on a core member, said core member defining openings at axial core portions of said core member for repetitive mounting on said shaft of said driving means.
Claim 8
Dependent Claim
48 words
An apparatus in accordance with claim 1, further comprising: another cylindrical cleaning member connected to said casing and positioned to resiliently contact another surface of the disk, said another cylindrical cleaning member having a longitudinal axis spaced from, and substantially parallel to, said radial axis of the disk.
Claim 9
Dependent Claim
21 words
An apparatus in accordance with claim 1, wherein: said cleaning member includes polishing materials for polishing the surface of the disk.
Claim 10
Dependent Claim
31 words
An apparatus in accordance with claim 1, wherein: said holder means is fitted into a center opening of the disk said cleaning member is positioned eccentrically with respect to the disk.
Claim 11
Dependent Claim
31 words
An apparatus in accordance with claim 1, wherein: said driving means rotates the disk through rotation of said cleaning member and said resilient contact between said cleaning member and the disk.
Claim 12
Dependent Claim
47 words
An apparatus in accordance with claim 10, wherein: said driving means rotates said cleaning member about said longitudinal axis of said cleaning member and rotates the disk about an axial axis of said disk to remove particles from the disk in a radial direction of the disk.
Claim 13
Dependent Claim
32 words
An apparatus in accordance with claim 1, wherein: the disk is a standard optical disk and said cleaning member extends over all readable portions of the disk during rotation of the disk.
