Abstract

PURPOSE:To eliminate waste of space above a developing machine and to reduce the size of a copying machine itself by arranging a toner box in a proper place except the main structure of the copying machine. CONSTITUTION:A toner in a toner box 1 is conveyed with a normally rotating auger 6 through a toner conveying pipe 3 toward the upper part of a developing device 6. It is dispersed and fed into the machine 2 through a slit 8 with a dispenser roll 4 arranged in a roll case 5 above the machine 2. At that time, the toner which does not reach the slit 8 but advances farther than it through the end of the pipe 3 is reversely conveyed with a reversely rotating auger 7 toward the toner box 1, and it is conveyed toward the slit 8 with the roll 4 while it is reversely conveyed, and dispersed and fed into the machine 2.

があった。(Prior Art) A toner replenishing device for a developing machine in a conventional copying machine has a roll for uniformly distributing and replenishing toner to the developing machine, and the roll has approximately the same length in the axial direction. The toner box is generally connected to the upper part of the developing machine. Therefore, the upper part of the developing machine is occupied by the toner box, resulting in wasted space, and this waste becomes even greater in the case of a large-sized machine.

０．４程度とする。In these figures, a toner box 1 is placed at a suitable location outside the copying machine mechanism (not shown), and a toner conveying tube 3 is placed from the toner box 1 to the upper part K of the developing machine 2. A portion of the toner conveying tube 3 located above the developing device 2 is connected to the developing device 21C via a roll case 5 containing a dispenser roll 4, while a forward rotation auger is provided inside the toner conveying tube 3. 6 and a reverse rotation auger 7 are arranged in parallel, and the rotation speed of the forward rotation auger 61C and the reverse rotation auger 7 is determined by a drive mechanism (not shown). are set in a somewhat random manner. The proportion varies slightly depending on the amount of toner used and the fluidity of the toner, but it ranges from 1:09 to 1:
It should be about 0.4.

。The toner stored in the toner box 1 is conveyed through the toner conveying tube 3 toward the upper part of the developing device 2 by the forward rotation auger 6. Then, it is dispersed and replenished into the developing machine 2 via the slit 8 by a dispenser roll 4 disposed in a roll case 5 at the upper part of the developing machine 2 . At this time, the toner that has not reached the sleeve 8 and has been conveyed to the inner part of the toner conveying tube 3 is conveyed backwards toward the toner box 1 by the reverse rotation auger 7. While being fed, the toner is conveyed by the dispenser roll 4 to the slit 8, from where it is dispersed and replenished into the developing machine 2.

た効果を有する。(Effects of the Invention) The present invention is configured and used as described in 5 above, and by arranging the toner box l at a suitable location outside the copying machine mechanism, the space that conventionally occurs above the developing machine 2 can be saved. It is possible to reduce the size of the copying machine itself by eliminating unnecessary waste.
Alternatively, it is possible to use this location as a location for other devices of the copying machine, and also toner can be directed from the toner box 1 located outside the copying machine mechanism to the upper part of the developing machine 2. When conveying the toner, the toner is transferred to the developing machine 2.
When replenishing the toner inside, the rotational speed ratio of the forward rotation auger 6 and the reverse rotation auger disposed inside the toner conveying tube 3 is set so that the rotation speed of the reverse rotation auger 7 is slightly lower than that of the forward rotation auger 6. Therefore, there is no possibility that a large amount of toner is replenished on the side of the toner box, or that the inner part of the toner conveying tube 3 is clogged, and uniform replenishment can be achieved at all times.
