US4348103A — Cleaning apparatus for photosensitive member of e…

Claim 1

Independent Claim 132 words

A cleaning apparatus for a photosensitive member of an electrophotographic machine, comprising a cleaning brush disposed to be movable into contact with or away from a photosensitive member which is adapted to carry an electrostatic latent image thereon, the brush being disposed to be maintained in contact with said photosensitive member while rotating to remove therefrom unnecessary developing toner which attaches to the photosensitive member; trap means for collecting unnecessary developing toner removed by the cleaning brush; a striker rod disposed in abutment against the cleaning brush and to be rotatable for removing developing toner from the brush; and drive means for causing an angular movement of the striker rod through a given angle in association with the movement of the cleaning brush into contact with or away from the photosensitive member.

Claim 2

Dependent Claim 132 words

A cleaning apparatus for a photosensitive member of an electrophotographic machine, comprising a cleaning brush disposed to be movable into contact with or away from a photosensitive member which is adapted to carry an electrostatic latent image thereon, the brush being disposed to be maintained in contact with said photosensitive member while rotating to remove therefrom unnecessary developing toner which attaches to the photosensitive member; trap means for collecting unnecessary developing toner removed by the cleaning brush; a striker rod disposed in abutment against the cleaning brush and to be rotatable for removing developing toner from the brush; and drive means for causing an angular movement of the striker rod through a given angle in association with the movement of the cleaning brush into contact with or away from the photosensitive member.

Claim 3

Dependent Claim 71 words

A cleaning apparatus according to claim 1 further including means for normally maintaining the cleaning brush in contact with the photosensitive member and for moving the cleaning brush away therefrom when a multiple copy is to be produced from an electrostatic latent image formed on the photosensitive member, and for returning the cleaning brush to its original position for contact with the photosensitive member upon completion of the multiple copy operation.

Claim 4

Dependent Claim 47 words

A cleaning apparatus according to claim 1 in which the cleaning brush includes a rotary shaft, the opposite ends of which are carried by a pair of rockable arms so as to be movable into contact with or away from the photosensitive member as the arms rock.

Claim 5

Dependent Claim 31 words

A cleaning apparatus according to claim 1 in which the striker rod is rotatably mounted on a stationary member and is disposed on the path of rotation of the cleaning brush.

Claim 6

Dependent Claim 101 words

A cleaning apparatus according to claim 3 in which the drive means associated with the striker rod comprises a ratchet wheel fixedly mounted on one end of the striker rod, and a feed pawl mounted on one of the rockable arms associated with the cleaning brush and actuated by movement of said rockable arm, the movement of the feed pawl causing an angular movement of the ratchet wheel in one direction to cause an angular movement of the striker rod as one of the rockable arms rocks to move the cleaning brush away from or into contact with the photosensitive member.

Claim 7

Dependent Claim 145 words

A cleaning apparatus for a photosensitive member of an electrophotographic machine, comprising: a cleaning brush mounted for movement relative to a photosensitive member which is adapted to carry an electrostatic latent image thereon, said cleaning brush being disposed to be maintained in contact with said photosensitive member while the latter is rotating to remove therefrom unnecessary developing toner which attaches to the photosensitive member; trap means for collecting unnecessary developing toner removed by the cleaning brush; a striker rod mounted in contact with said cleaning brush and mounted for rotation for removing developing toner from said brush; drive means for moving said cleaning brush relative to said photosensitive member; and means responsive to said drive means and the movement of said cleaning brush for causing an angular movement of the striker rod through a given angle in association with the movement of said cleaning brush.

Claim 8

Dependent Claim 145 words

A cleaning apparatus for a photosensitive member of an electrophotographic machine, comprising: a cleaning brush mounted for movement relative to a photosensitive member which is adapted to carry an electrostatic latent image thereon, said cleaning brush being disposed to be maintained in contact with said photosensitive member while the latter is rotating to remove therefrom unnecessary developing toner which attaches to the photosensitive member; trap means for collecting unnecessary developing toner removed by the cleaning brush; a striker rod mounted in contact with said cleaning brush and mounted for rotation for removing developing toner from said brush; drive means for moving said cleaning brush relative to said photosensitive member; and means responsive to said drive means and the movement of said cleaning brush for causing an angular movement of the striker rod through a given angle in association with the movement of said cleaning brush.
