Abstract

PURPOSE:To prevent toner from leaking out by fitting shutters which are united through a connection part inside and outside a storage part and a cartridge, and opening and closing them associatively. CONSTITUTION:This mechanism has 1st shutters 1a and 1b which cover the opening part of the storage part 4 for toner 7 integrally across the connection part from the inside and outside and a 2nd shutter 2 which is provided on the side of a cartridge 5 to cover the opening part of the cartridge 5 and is opened and closed at a toner supply position associatively with the 1st shutters 1a and 1b. Consequently, neither the toner 7 in the storage part 4 nor the toner 7 in the cartridge 5 leaks out and neither the outside of the storage part 4 nor the outside of the cartridge 5 is stained, so the hand never becomes dirty.

The newly attached toner 7 moves together with the shutter 1a. However, since the gaps are filled with each sealing material 6, no leakage occurs. However, every time the toner replenishment shutter is opened and closed two or three times, some of the toner 7 leaks out even though it is blocked by the shutters 1a and 2 and the gaps are filled with each sealant 6. It starts to leak, and it sticks to the outside of the storage section 4 and the cartridge 5, and even your hands. 7 will not be omitted).

外側やカートリッジ５の外側を汚すことはない。At the same time, the previously adhered toner 7 in the storage section 4 and the newly adhered toner 7 move together with the movement of the toner supply shutter. Further, a portion of the toner 7 in the cartridge 5 also adheres to the shutter 2 and moves together with the shutter 2. However, the toner 7 is prevented from entering the outside of the shutter 1b (the side in contact with the connection part 1c) at the connection part IC, and the gaps are filled with each sealing material 6. If the seal material 6 between the shutter 1b and the storage section 4 were to open and close over and over again, the seal material 6 between the shutter 1b and the storage section 4 would Even if the toner 7 deteriorates and leaks to the outside of the shutter 1b, the storage section 4
Due to the sealing material 6 between the toner replenishing shutter and the shutter 1a, and because the connecting portion 1c comes into contact with the storage portion 4 when the toner replenishing shutter is fully opened, there is no gap, thereby preventing the toner from adhering to the inside of the shutter 1a. Also, the toner 7 is placed on the shutter 1a.
Even if it adheres, the amount is very small and will not stain the outside of the storage section 4 or the outside of the cartridge 5.
