Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
15 words
A developing device as in claim 1 wherein said tray is semicircular in transverse cross-section.
Claim 2
Dependent Claim
43 words
A developing device as in claim 2 wherein said agitating and moving means comprise a plurality of vanes mounted for rotation about an axis parallel to the length of the tray in the direction of movement of the sheets introduced into the tray.
Claim 3
Dependent Claim
72 words
A developing device as in claim 3 wherein each of said vanes has a front end portion which is bent in a direction substantially opposite to and forming an angle with the direction of rotation of the vane, whereby a wedge-shaped space gradually diverging in the direction of rotation of the vane is formed between the front end portion of each vane and the inner curved wall surface of the developing tray.
Claim 4
Dependent Claim
58 words
A developing device as in claim 4 including means for causing rotation of the vanes in the direction of movement of the sheet introduced into the tray at the time a sheet is introduced into the tray and for stopping the rotation of the vanes when the sheet introduced into the tray is extracted by said extracting means.
Claim 5
Dependent Claim
29 words
A developing device as in claim 5 wherein said extracting means include vibrating brush means for removing, from the extracted sheet, powder developing agent that may have adhered thereto.
Claim 6
Dependent Claim
47 words
A developing device as in claim 6 wherein the vibrating brush means includes a pair of converging hair brushes flanking the path of a developed sheet extracted from the tray, a pair of roller-sponge brush units, and means for vibrating the hair brushes and the sponge brushes.
Claim 7
Dependent Claim
46 words
A developing device as in claim 5 wherein the extracting means includes brushes for removing powder which may have adhered to the extracted sheet, and including means for vibrating the brushes and for transmitting vibrations to the tray for facilitating agitation of the developing agent therein.
Claim 8
Dependent Claim
154 words
A developing device using powder developing agent and comprising a developing tray holding a quantity of said developing agent and having a trough-shaped bottom wall which is smoothly curved in transverse section, means adjacent one end of said curved bottom wall for introducing a sheet into the tray, and means for agitating the powder developing agent in the tray and for moving the sheet from the end of the curved bottom wall at which it is introduced into the tray toward the other end of said bottom wall, said agitating and moving means being out of direct contact with the moving sheet but acting thereon through the agitated developing agent, said agitating and moving means comprising a plurality of vanes and means for mounting the vanes for rotation about an axis which is within the curvature of said curved bottom wall and in the direction of movement of the sheet introduced into the tray.
Claim 9
Dependent Claim
75 words
A developing device as in claim 9 wherein each of said vanes has a front end portion which is bent in a direction substantially opposite to and forming an angle of less than 180* with the direction of rotation of the vane, whereby a wedge-shaped space gradually diverging in the direction of rotation of the vane is formed between the front end portioN of each vane and the curved wall surface of the developing tray.
Claim 10
Dependent Claim
44 words
A developing device as in claim 10 including means for causing said rotation of the vanes in response to the introduction of a sheet into the tray and for stopping said rotation of the vanes in response to a sheet leaving the developing tray.
Claim 11
Dependent Claim
24 words
A device as in claim 9 including means adjacent the other end of said curved bottom wall for extracting a sheet from the tray.
