Form an opening to drop the stored toner,
A shutter formed by an elastic sheet inside the toner cartridge to open and close the opening is slidably provided along the curved surface, and a part of the shutter is held inside the toner cartridge. An operating member having a holding portion is provided so as to be able to move up and down, the operating member is provided with a projecting portion that projects to the outside of the toner cartridge, and the toner container is provided with a receiving portion that supports the lower surface of the projecting portion. A locking body including a leg that contacts the cartridge and a claw that engages the protruding portion is rotatably attached to the toner container, and the claw is in a state where the leg contacts the side surface of the toner cartridge. The part is adapted to be engaged with the protruding part.

飛散を防止する。As a result, since the opening of the toner cartridge is formed on the curved surface, the shutter formed by the elastic sheet is elastically curved and slides to maintain the airtightness when the opening is closed. When the toner cartridge is inserted through the upper opening of the toner container, the lower surface of the projecting portion is supported by the receiving portion, so that the actuating member rises relative to the toner cartridge and pulls up the shutter to open the opening. Therefore,
The toner in the toner cartridge drops into the toner container. When the toner cartridge is pulled up from the toner container, the upper surface of the protruding portion of the actuating body is pressed by the claw portion of the locking body.Therefore, as the toner cartridge is pulled up, the shutter performs the closing operation, closing the opening and closing To prevent the scattering of.

いる。Embodiment An embodiment of the present invention will be described with reference to the drawings. A toner container 1 and a toner cartridge 2 having an upper surface opening are provided. Pins 3 are provided upright on both sides of one end of the toner cartridge 2 and a notch 4 having an upper opening for holding the pins 3 rotatably is formed in the toner container 1. Two curved surfaces 5 and a bank 6 located between these curved surfaces 5 are formed in parallel on the bottom surface of the toner cartridge 2 and a plurality of openings 7 are formed in each curved surface 5. Has been done. The actuating member 8 provided in the toner cartridge 2 has a horizontally elongated member 9 having a T-shaped cross section, the lower part of which is protruded from a slit 6a formed in the bank portion 6 to the outside, and the opening 7 is provided. It comprises a horizontally long holding portion 11 for fixing the covering shutter 10 to the member 9. An inclined surface 11a is formed on the upper surface of the holding portion 11 so as to gradually incline downward toward the outside. The shutter 10 is formed of a sheet of mylar or the like having elasticity. At both ends of the member 9, vertically long windows formed on both side surfaces of the toner cartridge 2
A protrusion 13 protruding from 12 is formed. The inner surface of the window 12 is closed by a rubber plate 15 in which a vertically long cut 14 is formed.

る。Further, as is apparent from FIG. 6, an inclined surface 24 is formed at the edge of the opening 7 along the curved direction of the curved surface 5 so as to be inclined in a direction in which the opening area of the opening 7 is gradually increased as it goes upward. ing. Further, on both inner side surfaces of the toner cartridge 2 are formed grooves 25 along the inner peripheral surface. These grooves
25, both side edges of the shutter 10 are slidably held.

より、トナーカートリツジ２のトナー26がトナー容器１
に補給される。In such a structure, as shown in FIG. 1 and FIG. 3, the shutter 10 has an effect of restoring to a flat state by its elasticity and adheres to the edge of the opening 7 to keep the opening 7 airtight. Next, the pin 3 of the toner cartridge 2 is cut out 4
When the toner cartridge 2 is inserted into the toner container 1, the toner cartridge 2 is rotated around the pin 3 as a fulcrum and inserted into the toner container 1.
When the actuating member 8 moves upward relative to the toner cartridge 1 by receiving an upward force from the engaging member 21,
The leg 22 is pressed by the bottom of the bank 6 of the toner cartridge 2 to rotate, and the claw 23 is engaged with the upper surface of the protrusion 13. This state is as shown in FIGS. 2 and 4, and the upward movement of the actuating body 8 causes the shutter 10 to be pulled upward and guided by the groove 25 to slide on the curved surface 5 to open the opening 7. To do. As a result, the toner 26 of the toner cartridge 2 is transferred to the toner container 1.
Will be replenished.

また、トナー容器１からトナーカートリツジ２を引き上

口７を閉塞する。When the toner cartridge 2 is pulled up from the toner container 1, the pawl portion 23 of the locking body 21 presses the upper surface of the projecting portion 13 until the leg portion 22 of the locking body 21 separates from the bottom surface of the bank portion 6, thereby operating. The body 8 is lowered relative to the toner cartridge 2. Therefore, the shutter 10 slides on the curved surface 5 to close the opening 7.

無駄なく落下させることができる。As described above, since the toner cartridge 2 is automatically opened and closed when the toner cartridge 2 is attached to and detached from the toner container 1,
The toner 26 can be easily replenished, the toner 26 does not spill, and the hands are not soiled, which is hygienic. Further, since the shutter 10 straddles the two curved surfaces 5 and the central portion is held by the actuation body 8, assuming that the movement amount of the actuation body 8 is 1, the shutter 10 shows 1 movement on each side and 2 movements on both sides. Shows the movement of. Therefore, the opening 7 for the movement of the actuating body 8
Therefore, the toner 26 inside the toner cartridge 2 can be efficiently transferred to the toner container 1 by increasing the opening ratio of the toner cartridge 2. At this time, since the inclined surface 11a is formed on the upper surface of the holding portion 11 and the inclined surface 24 is formed on the edge of the opening 7 along the curved direction of the curved surface 5, the toner 26 in the toner cartridge 2 is removed. It can be dropped without waste.

有する。As described above, the present invention is provided with the toner container having the upper surface opening and the toner cartridge inserted into the toner container.
A curved surface is formed on the bottom surface of the toner cartridge, an opening for dropping the toner stored in the toner cartridge is formed on the curved surface, and the toner cartridge is formed by an elastic sheet inside the toner cartridge. A shutter that opens and closes an opening is slidably provided along the curved surface, and an operating body having a holding portion that holds a part of the shutter is provided inside the toner cartridge so as to be vertically movable. Is provided with a protrusion protruding outside the toner cartridge, a receiving portion for supporting the lower surface of the protrusion is formed in the toner container, and a leg that abuts the toner cartridge and a claw portion that engages with the protrusion. Is attached to the toner container rotatably, and the claw portion is engaged with the protruding portion in a state where the leg is in contact with the side surface of the toner cartridge. Since so as to, since the opening of the toner car Toritsuji is formed on the curved surface, can be a shutter formed by a sheet having elasticity is brought into close contact with the edge of the opening to maintain the airtightness at the opening closed,
Further, when the toner cartridge is inserted from the opening of the upper surface of the toner container, the lower surface of the protruding portion is supported by the receiving portion, so that the actuating body is relatively raised with respect to the toner cartridge and the shutter is pulled up to automatically open the opening. The toner inside the toner cartridge can be dropped into the toner container by further opening it, and by providing the toner container with a retractable locking body having a claw portion that engages with the upper surface of the protrusion,
When the toner cartridge is pulled up from the toner container, the claws of the locking body hold down the upper surface of the projecting portion of the actuating member, and the closing operation of the shutter can be reliably performed.
