  • Patent number: 4122981
    Abstract: A toner dispensing device for use in a developing apparatus of an electrophotographic copying machine. The device includes a toner tank mounted on the developing apparatus, a horizontal slit formed at a lower portion of the toner tank, a toner supplying plate which is adapted to reciprocate through the slit for supplying toner at constantly uniform rates from a plurality of openings formed in the same plate, and a stabilizing plate pivotally disposed in the toner tank for dividing the toner tank into upper and lower portions. When the toner supplying plate strikes in its return motion against the stabilizing plate, a predetermined amount of toner is supplied from the upper portion into the lower portion through openings formed in the stabilizing plate for maintaining a predetermined amount of toner in the lower portion at a uniform density.

  • Patent number: 4113374
    Abstract: The present invention is an electrophotographic copying apparatus which includes a group of switches disposed along the path of the copy paper. These switches are so arranged as to control the functions of corona charging, exposure and aligning the forward edge of the image formed on the photoreceptor with the leading edge of the copy paper, while the starting of the transfer device and the function of the copy paper separation device are controlled through a control cam which is driven by actuating signals produced by one of these switches. Since the developing and transfer functions are arranged to be suspended by a drum cam rotating as one unit with the photoreceptor drum, the possibility of copy paper jamming is decreased to a large extent through reduction of the number of switches employed, while undesirable developing and transfer at the slot portion or seam portion of the photoreceptor are advantageously eliminated.

  • Patent number: 4065120
    Abstract: Slidably and pivotally mounted means for stripping copey paper from one or both rolls of a fuser assembly in a photocopying machine. Spring means urging the stripping means into contact with a roll is normally countered by a component of frictional force exerted by the roll on the stripping means, thereby avoiding exertion of undue pressure on the roll. If copy paper becomes adhered to and cannot be detached in a normal manner from the roll, the stripping means is moved to a position in which the tip portion thereof no longer contacts the roll, thereby avoiding damage to the roll and stripping means.
