Abstract: PURPOSE:To stably and uniformly perform the electrostatic coating of developer toner by providing plural balls containing partially soft magnetic materials, and constraining the plural balls by a magnetic field formed by the magnetic material. CONSTITUTION:A charge powdering device 42 is comprised of a pair of magnets 45 rotatably by a driving device arranged at two planes in the longitudinal direction of a toner case, and a large number of large and small balls 46 held rotatably by the magnetic field formed by the pair of magnets 45. The surface of the ball 46 is coated with a material containing th soft magnetic material, for example, ferrite, an amorphous material, etc., in the inside and easy to be charged in polarity opposite to that of the developer toner 44 that is a material arranged at a different terminal in a charge string.

Title: Contact type image reader
Inventor: SAOTOME SUMITOSHI
IPC: H04N1/00
Filed: 1989-06-23
Abstract: PURPOSE:To carry even an original in which the paper quality and bendability of the original are weak by making the rotating speed of a bristle brush roller one- to two-fold to the rotating speed of an original carrying roller in a facsimile, a copying machine, etc. CONSTITUTION:First, an original 7 is set. When a paper detecting sensor 6 is operated, carrying and driving rollers 3 and 3', carrying follower rollers 4 and 4', a core metal 9 and a bristle brush 8 start the rotations. The original 7 is led in by the carrying driving roller 3 and carrying follower roller 4, the original 7 is brought into close contact on the glass surface of a reader 2 by the bristle brush 8, an image is read, and the original 7 is discharged to a paper discharge tray 5 by the carrying driving and roller 3' and carrying roller 4'. When the bristle brush 8 is rotated at the time of read, since the bristle head rises up by a centrifugal force, a rigidity is remarkably increased in comparison with a still time, and the original 7 can be brought into close contact onto the glass surface of the reader 2. The rotating speed of the bristle brush 8 is made one- to two-fold to the rotating circumferential speed of the carrying driving roller 3. Thus, even when a waved original comes, the fear of the generation of wrinkles can be eliminated by a press contact.

Title: Blade supporting device of focal-plane shutter for camera
Inventor: NEMOTO ICHIRO
IPC: G03B9/36
Filed: 1993-06-30
Abstract: PURPOSE:To prevent light shielding property from being deteriorated before and after an exposure action by making a distance between the axial supporting part of an arm and the coupling part of a slit forming blade with the arm shorter than a distance between an optional point in a shutter aperture and the axial supporting part of an arm. CONSTITUTION:An open shutter blade group 3 is constituted of the slit forming blade 3a and covering blades 3b-3d and respectively pivotally supported by the arms 9 and 10 so as to be freely turned. The arm 9 is freely turnably fitted to a substrate 1 through a pin 1b and the arm 10 is freely turnably fitted to the substrate 1 through a pin 1c. The pin 1c is positioned at a place where the distance between the pin 1c and the optional point in the shutter aperture 1a is longer than the distance R to the center of an axial supporting pin by which the blade 3a is coupled and supported by the arm 10. Therefore, since the moving locus of the axial supporting pin is not passed through the aperture 1a when the exposure action is executed, the blade 3a is suppressed from being vibrated in the optical axis direction of a shutter.
